  • Trouble getting SSL to work with django + nginx + wsgi

    - by Kevin
    I've followed a couple of examples for Django + nginx + wsgi + ssl, but I can't get them to work. I simply get an error in my browser than I can't connect. I'm running two websites off the host. The config files are identical except for the ip addresses, server names, and directories. When neither use SSL, they work fine. When I try to listen on 443 with one of them, I can't connect to either. My config files are below, and any suggestions would be appreciated. server{ listen xxx.xxx.xxx.xxx:80; server_name sub.domain.com; access_log /home/django/logs/nginx_customerdb_http_access.log; error_log /home/django/logs/nginx_customerdb_http_error.log; location / { proxy_pass http://127.0.0.1:8080; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffers 32 4k; } location /site_media/ { alias /home/django/customerdb_site_media/; } location /admin-media/ { alias /home/django/django_admin_media/; } } server{ listen xxx.xxx.xxx.xxx:443; server_name sub.domain.com; access_log /home/django/logs/nginx_customerdb_http_access.log; error_log /home/django/logs/nginx_customerdb_http_error.log; ssl on; ssl_certificate sub.domain.com.crt; ssl_certificate_key sub.domain.com.key; ssl_prefer_server_ciphers on; location / { proxy_pass http://127.0.0.1:8080; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Protocol https; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffers 32 4k; } location /site_media/ { alias /home/django/customerdb_site_media/; } location /admin-media/ { alias /home/django/django_admin_media/; } } <VirtualHost *:8080> ServerName xxx.xxx.xxx.xxx ServerAlias xxx.xxx.xxx.xxx LogLevel warn ErrorLog /home/django/logs/apache_customerdb_error.log CustomLog /home/django/logs/apache_customerdb_access.log combined WSGIScriptAlias / /home/django/customerdb/apache/django.wsgi WSGIDaemonProcess customerdb_wsgi processes=4 threads=5 WSGIProcessGroup customerdb_wsgi SetEnvIf X-Forwarded-Protocol "^https$" HTTPS=on </VirtualHost> UDPATE: the existence of two sites (on separate IPs) on the host is the issue. if i delete the other site, the setting above mostly work. doing so also brings up another issue: chrome doesn't accept the site as secure saying that some content is not encrypted.

  • How to setup stunnel so that gmail can use my own smtp server to send messages.

    - by igorhvr
    I am trying to setup gmail to send messages using my own smtp server. I am doing this by using stunnel over a non-ssl enabled server. I am able to use my own smtp client with ssl enabled just fine to my server. Unfortunately, however, gmail seems to be unable to connect to my stunnel port. Gmail seems to be simply closing the connection right after it is established - I get a "SSL socket closed on SSL_read" on my server logs. On gmail, I get a "We are having trouble authenticating with your other mail service. Please try changing your SSL settings. If you continue to experience difficulties, please contact your other email provider for further instructions." message. Any help / tips on figuring this out will be appreciated. My certificate is self-signed - could this perhaps be related to the problem I am experiencing? I pasted the entire SSL session (logs from my server) below. 2011.01.02 16:56:20 LOG7[20897:3082491584]: Service ssmtp accepted FD=0 from 209.85.210.171:46858 2011.01.02 16:56:20 LOG7[20897:3082267504]: Service ssmtp started 2011.01.02 16:56:20 LOG7[20897:3082267504]: FD=0 in non-blocking mode 2011.01.02 16:56:20 LOG7[20897:3082267504]: Option TCP_NODELAY set on local socket 2011.01.02 16:56:20 LOG7[20897:3082267504]: Waiting for a libwrap process 2011.01.02 16:56:20 LOG7[20897:3082267504]: Acquired libwrap process #0 2011.01.02 16:56:20 LOG7[20897:3082267504]: Releasing libwrap process #0 2011.01.02 16:56:20 LOG7[20897:3082267504]: Released libwrap process #0 2011.01.02 16:56:20 LOG7[20897:3082267504]: Service ssmtp permitted by libwrap from 209.85.210.171:46858 2011.01.02 16:56:20 LOG5[20897:3082267504]: Service ssmtp accepted connection from 209.85.210.171:46858 2011.01.02 16:56:20 LOG7[20897:3082267504]: FD=1 in non-blocking mode 2011.01.02 16:56:20 LOG6[20897:3082267504]: connect_blocking: connecting 127.0.0.1:25 2011.01.02 16:56:20 LOG7[20897:3082267504]: connect_blocking: s_poll_wait 127.0.0.1:25: waiting 10 seconds 2011.01.02 16:56:20 LOG5[20897:3082267504]: connect_blocking: connected 127.0.0.1:25 2011.01.02 16:56:20 LOG5[20897:3082267504]: Service ssmtp connected remote server from 127.0.0.1:3701 2011.01.02 16:56:20 LOG7[20897:3082267504]: Remote FD=1 initialized 2011.01.02 16:56:20 LOG7[20897:3082267504]: Option TCP_NODELAY set on remote socket 2011.01.02 16:56:20 LOG5[20897:3082267504]: Negotiations for smtp (server side) started 2011.01.02 16:56:20 LOG7[20897:3082267504]: RFC 2487 not detected 2011.01.02 16:56:20 LOG5[20897:3082267504]: Protocol negotiations succeeded 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): before/accept initialization 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 read client hello A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 write server hello A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 write certificate A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 write certificate request A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 flush data 2011.01.02 16:56:20 LOG5[20897:3082267504]: CRL: verification passed 2011.01.02 16:56:20 LOG5[20897:3082267504]: VERIFY OK: depth=2, /C=US/O=Equifax/OU=Equifax Secure Certificate Authority 2011.01.02 16:56:20 LOG5[20897:3082267504]: CRL: verification passed 2011.01.02 16:56:20 LOG5[20897:3082267504]: VERIFY OK: depth=1, /C=US/O=Google Inc/CN=Google Internet Authority 2011.01.02 16:56:20 LOG5[20897:3082267504]: CRL: verification passed 2011.01.02 16:56:20 LOG5[20897:3082267504]: VERIFY OK: depth=0, /C=US/ST=California/L=Mountain View/O=Google Inc/CN=smtp.gmail.com 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 read client certificate A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 read client key exchange A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 read certificate verify A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 read finished A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 write change cipher spec A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 write finished A 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL state (accept): SSLv3 flush data 2011.01.02 16:56:20 LOG7[20897:3082267504]: 1 items in the session cache 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 client connects (SSL_connect()) 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 client connects that finished 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 client renegotiations requested 2011.01.02 16:56:20 LOG7[20897:3082267504]: 1 server connects (SSL_accept()) 2011.01.02 16:56:20 LOG7[20897:3082267504]: 1 server connects that finished 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 server renegotiations requested 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 session cache hits 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 external session cache hits 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 session cache misses 2011.01.02 16:56:20 LOG7[20897:3082267504]: 0 session cache timeouts 2011.01.02 16:56:20 LOG6[20897:3082267504]: SSL accepted: new session negotiated 2011.01.02 16:56:20 LOG6[20897:3082267504]: Negotiated ciphers: RC4-MD5 SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 2011.01.02 16:56:20 LOG7[20897:3082267504]: SSL socket closed on SSL_read 2011.01.02 16:56:20 LOG7[20897:3082267504]: Socket write shutdown 2011.01.02 16:56:20 LOG5[20897:3082267504]: Connection closed: 167 bytes sent to SSL, 37 bytes sent to socket 2011.01.02 16:56:20 LOG7[20897:3082267504]: Service ssmtp finished (0 left)

  • Forwarding rsyslog to syslog-ng, with FQDN and facility separation

    - by Joshua Miller
    I'm attempting to configure my rsyslog clients to forward messages to my syslog-ng log repository systems. Forwarding messages works "out of the box", but my clients are logging short names, not FQDNs. As a result the messages on the syslog repo use short names as well, which is a problem because one can't determine which system the message originated from easily. My clients get their names through DHCP / DNS. I've tried a number of solutions trying to get this working, but without success. I'm using rsyslog 4.6.2 and syslog-ng 3.2.5. I've tried setting $PreserveFQDN on as the first directive in /etc/rsyslog.conf (and restarting rsyslog of course). It seems to have no effect. hostname --fqdn on the client returns the proper FQDN, so the problem isn't whether the system can actually figure out its own FQDN. $LocalHostName <fqdn> looked promising, but this directive isn't available in my version of rsyslog (Available since 4.7.4+, 5.7.3+, 6.1.3+). Upgrading isn't an option at the moment. Configuring the syslog-ng server to populate names based on reverse lookups via DNS isn't an option. There are complexities with reverse DNS and the public cloud. Specifying for the forwarder to use a custom template seems like a viable option at first glance. I can specify the following, which causes local logging to begin using the FQDN on the syslog-ng repo. $template MyTemplate, "%timestamp% <FQDN> %syslogtag%%msg%" $ActionForwardDefaultTemplate MyTemplate However, when I put this in place syslog-ng seems to be unable to categorize messages by facility or priority. Messages come in as FQDN, but everything is put in to user.log. When I don't use the custom template, messages are properly categorized under facility and priority, but with the short name. So, in summary, if I manually trick rsyslog into including the FQDN, priority and facility becomes lost details to syslog-ng. How can I get rsyslog to do FQDN logging which works properly going to a syslog-ng repository? rsyslog client config: $ModLoad imuxsock.so # provides support for local system logging (e.g. via logger command) $ModLoad imklog.so # provides kernel logging support (previously done by rklogd) $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg * uucp,news.crit /var/log/spooler local7.* /var/log/boot.log $WorkDirectory /var/spool/rsyslog # where to place spool files $ActionQueueFileName fwdRule1 # unique name prefix for spool files $ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible) $ActionQueueSaveOnShutdown on # save messages to disk on shutdown $ActionQueueType LinkedList # run asynchronously $ActionResumeRetryCount -1 # infinite retries if host is down *.* @syslog-ng1.example.com *.* @syslog-ng2.example.com syslog-ng configuration (abridged for brevity): options { flush_lines (0); time_reopen (10); log_fifo_size (1000); long_hostnames (off); use_dns (no); use_fqdn (yes); create_dirs (no); keep_hostname (yes); }; source src { unix-stream("/dev/log"); internal(); udp(ip(0.0.0.0) port(514)); }; destination per_host_destination { file( "/var/log/syslog-ng/devices/$HOST/$FACILITY.log" owner("root") group("root") perm(0644) dir_owner(root) dir_group(root) dir_perm(0775) create_dirs(yes)); }; log { source(src); destination(per_facility_destination); };

  • Ubuntu 14.04, OpenLDAP TLS problems

    So i have set up an openldap server using this guide here. It worked fine. But as i want to use sssd i also need TLS to be working for ldap.

  • RAID controller dropping the wrong drive

    - by bramp
    I've been having an issue with 3ware 9500S-8 RAID 10, and I have contracted their tech support, but I wanted to hear the serverfault community's recommendations. Firstly, all my data is backuped and secure, so I don't mind blowing my RAID away if I have to. But let me describe the problem I've been seeing. A month ago, disk 6 dropped out of the RAID. It is mirrored with disk 7, so I wasn't that bothered. I went to the data centre and replaced it. When I got back to the office, I noticed that disk 6 will still not in the RAID, and in fact the controller was show the name of the old drive still. A week later I went back and replace the drive again, thinking I might have swapped in a bad drive. Still the same problem. I decided to reboot the machine, to see if that would "force" the controller into seeing the new drive. It did, and a rebuild started to happen (from disk 7). Eventually both drives were showing as good. A week later, the MySQL database has flagged the database is corrupt, and is unable to repair it. I don't know what has gone wrong, but I suspected this 6-7 pair. At this point I noticed that the RAID had constantly been verifying itself, over and over. Regardless of this I began to rebuild the database, which took about 19 hours. It's a big database. Near the end of the repair, the RAID controller told me it had dropped disk 7, and that some data was most likely corrupted. I contacted LSI tech support, and they very promptly started to help me. I mentioned that drive 7 had been dropped. They suspect that drive 7 was always at fault, and drive 6 had always been good. I want to know how often a RAID controller would drop the wrong drive (in this case dropping drive 6 a month ago, instead of 7). I foolishly didn't run smartctl on the drives before I started swapping them out. I just assumed the RAID controller knew what it was talking about. I think my plan of action is to replace drive 7, rebuild the array from scratch, double check smartctl on ALL the disks, and then start restoring my data again. I would appreciate anyone's input on what the correct procedure for swapping drives is, and how often failures like this happen. If anyone would like more information then I'd be happy to provide it. thanks in advance. Oh some more information. I'm running CentOS 5.3, with two RAID arrays, a simple RAID 1 for the OS, and RAID 10 for the database. Both arrays are on different controllers. The RAID 10 is made of 10 identical ST3640323AS drives, until I swapped in a SAMSUNG HD103SJ last month.

  • stunnel crashing

    - by Jay
    I'm trying to use stunnel to secure a legacy application's communications. I can't seem to get it setup and working. Can anyone provide any hints where I'm going wrong? Here's what I'm trying to accomplish: A windows service on a client machine connects to a server on port 7000 using TCP. I'd like to encrypt the communication between client and server. Here's what I've tried: Created a new server that accepts ssl connections on port 7443. Got a certificate for the server and installed it. That seems to work with my test setup. Installed stunnel on my windows machine (version 7.43 from the distribution archive file). Installed libssl32.dll and libeay32.dll in the same directory as stunnel.exe ( from the openssl-0.9.8h-1 binary distribution).

  • Pushing DNSSEC updates with offline keys

    - by eggyal
    In a non-professional capacity, I look after the DNS of some 18 domains: mostly personal/vanity domains for immediate family. I outsource the whole shebang to an inexpensive managed hosting provider with a web interface through which I manage the zones; since the provider also offers DNSSEC, I have successfully deployed that too. These domains are so unimportant that an attack targetted against them seems much less likely than a general compromise of my provider's systems, at which point the records of all their customers might be changed to misdirect traffic (perhaps with extremely long TTLs). DNSSEC could protect against such an attack, but only if the zone's private keys are not held by the hosting provider. So, I wonder: how can one keep DNSSEC private keys offline yet still transfer signed zones to an outsourced DNS host? The most obvious answer (to me, at least) is to run one's own shadow/hidden master (from which the provider can slave) and then copy offline-signed zonefiles to the master as required. The problem is that the only machine I (want to*) control is my personal laptop, which usually connects from a typical home ADSL (behind NAT over a dynamically-assigned IP address). Having them slave from that (e.g. with a very long Expiry time on the zone for periods when my laptop is offline/unavailable) would not only require a Dynamic DNS record from which they can slave (if indeed they can slave from a named host rather than a static IP address), but would also involve me running a DNS server on my laptop and opening both it and my home network up to the incoming zone transfer requests: not ideal. I would prefer a much more push-oriented design, whereby my laptop initiates transfer of offline-signed zonefiles/updates to the provider's servers. I looked into whether nsupdate could fit the bill: documentation is a little sketchy, but my testing (with BIND 9.7) suggests it can indeed update DNSSEC zones, but only where the server holds the keys to perform the zone signing; I have not found a way to have it take an update including the relevant RRSIG/NSEC/etc. records and have the server accept them. Is this a supported use-case? If not, I suspect the only solutions which could fit the bill will involve non-DNS-based transfer of the zone updates and would welcome recommendations that are supported by (hopefully inexpensive) hosting providers: SFTP/SCP? rsync? RDBMS replication? Proprietary API? Finally, what would be the practical implications of such a setup? Key rotation is jumping out at me as being an obvious difficulty, especially if my laptop is offline for extended periods. But the zones are extremely stable, so perhaps I could get away with long-lived ZSKs**...? * Whilst I could run a shadow/hidden master on e.g. an outsourced VPS, I dislike the overhead of having to secure / manage / monitor / maintain yet another system; not to mention the additional financial costs of so doing. ** Okay, this would enable a concerted attacker to replay outdated records—but the risk and impact of such are both tolerable in the case of these domains.

  • Squid - Logging to MySQL without empty rows/skipped records?

    - by Lee Ward
    I'm trying to figure out how to make Squid proxy log to MySQL. I know ACL order is pretty important but I'm not sure if I understand exactly what ACLs are or do, it's difficult to explain, but hopefully you'll see where I'm going with this as you read! I have created the lines to make Squid interact with a helper in squid.conf as follows: external_acl_type mysql_log %LOGIN %SRC %PROTO %URI php /etc/squid3/custom/mysql_lg.php acl ex_log external mysql_log http_access allow ex_log The external ACL helper (mysql_lg.php) is a PHP script and is as follows: error_reporting(0); if (! defined(STDIN)) { define("STDIN", fopen("php://stdin", "r")); } $res = mysql_connect('localhost', 'squid', 'testsquidpw'); $dbres = mysql_select_db('squid', $res); while (!feof(STDIN)) { $line = trim(fgets(STDIN)); $fields = explode(' ', $line); $user = rawurldecode($fields[0]); $cli_ip = rawurldecode($fields[1]); $protocol = rawurldecode($fields[2]); $uri = rawurldecode($fields[3]); $q = "INSERT INTO logs (id, user, cli_ip, protocol, url) VALUES ('', '".$user."', '".$cli_ip."', '".$protocol."', '".$uri."');"; mysql_query($q) or die (mysql_error()); if ($fault) { fwrite(STDOUT, "ERR\n"); }; fwrite(STDOUT, "OK\n"); } The configuration I have right now looks like this: ## Authentication Handler auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 30 auth_param negotiate program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param negotiate children 5 # Allow squid to update log external_acl_type mysql_log %LOGIN %SRC %PROTO %URI php /etc/squid3/custom/mysql_lg.php acl ex_log external mysql_log http_access allow ex_log acl localnet src 172.16.45.0/24 acl AuthorizedUsers proxy_auth REQUIRED acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl CONNECT method CONNECT acl blockeddomain url_regex "/etc/squid3/bl.acl" http_access deny blockeddomain deny_info ERR_BAD_GENERAL blockeddomain # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # Allow the internal network access to this proxy http_access allow localnet # Allow authorized users access to this proxy http_access allow AuthorizedUsers # FINAL RULE - Deny all other access to this proxy http_access deny all From testing, the closer to the bottom I place the logging lines the less it logs. Oftentimes, it even places empty rows in to the MySQL table. The file-based logs in /var/log/squid3/access.log are correct but many of the rows in the access logs are missing from the MySQL logs. I can't help but think it's down to the order I'm putting lines in because I want to log everything to MySQL, unauthenticated requests, blocked requests, which category blocked a specific request. The reason I want this in MySQL is because I'm trying to have everything managed via a custom web-based frontend and want to avoid using any shell commands and access to system log files if I can help it. The end result is to make it as easy as possible to maintain without keeping staff waiting on the phone whilst I add a new rule and reload the server! Hopefully someone can help me out here because this is very much a learning experience for me and I'm pretty stumped. Many thanks in advance for any help!

  • IPv6: Should I have private addresses?

    - by AlReece45
    Right now, we have a rack of servers. Every server right now has at least 2 IP addresses, one for the public interface, another for the private. The servers that have SSL websites on them have more IP addresses. We also have virtual servers, that are configured similarly. Private Network The private range is currently just used for backups and monitoring. Its a gigabit port, the interface usage does not usually get very high. There are other technologies we're considering using that would use this port: iSCSI (implementations usually recommends dedicating an interface to it, which would be yet another IP network), VPN to get access to the private range (something I'd rather avoid) dedicated database servers LDAP centralized configuration (like puppet) centralized logging We don't have any private addresses in our DNS records (only public addresses). For our servers to utilize the correct IP address for the right interface (and not hard code the IP address) probably requires setting up a private DNS server (So now we add 2 different dns entries to 2 different systems). Public Network Our public range has a variety of services include web, email, and ftp. There is a hardware firewall between our network and the "public" network. We have (relatively secure) method to instruct the firewall to open and close administrative access (web interfaces, ssh, etc) for our current IP address. With either solution discussed, the host-based firewalls will be configured as well. The public network currently runs at a dedicated 20Mbps link. There are a couple of legacy servers with fast-ethernet ports, but they are scheduled for decommissioning. All of the other production boxes have at least 2 Gigabit Ethernet ports. The more traffic-heavy servers have 4-6 available (none is using more than the 2 Gigabit ports right now). IPv6 I want to get an IPv6 prefix from our ISP. So at least every "server" has at least one IPv6 interface. We'll still need to keep the IPv4 addressees up and available for legacy clients (web servers and email at the very least). We have two IP networks right now. Adding the public IPv6 address would make it three. Just use IPv6? I'm thinking about just dumping the private IPv4 range and using the IPv6 range as the primary means of all communications. If an interface starts reaching its capacity, utilize the newly free interfaces to create a trunk. It has the advantage that if either the public or private traffic needs to exceed 1Gbps. The traffic for each interface is already analyzed on a regular basis to predict future bandwidth use. In the rare instances where bandwidth unexpected peaks: utilize QoS to ensure traffic (like our limited SSH access) is prioritized correctly so the problem can be corrected (if possible, our WAN is the bottleneck right now). It also has the advantage of not needing to make an entry for every private address. We may have private DNS (or just LDAP), but it'll be much more limited in scope with less entries to duplicate. Summary I'm trying to make this network as "simple" as possible. At the same time, I want to make sure its reliable, upgradeable, scalable, and (eventually) redundant. Having one IPv6 network, and a legacy IPv4 network seems to be the best solution to me. Regarding using assigned IPv6 addresses for both networks, sharing the available bandwidth on one (more trunked if needed): Are there any technical disadvantages (limitations, buffers, scalability)? Are there any other security considerations (asides from firewalls mentioned above) to consider? Are there regulations or other security requirements (like PCI-DSS) that this doesn't meet? Is there typical software for setting up a Linux network that doesn't have IPv6 support yet? (logging, ldap, puppet) Some other thing I didn't consider?

  • I am starting to think that Prevx.com isnt a legit site...but heres my long-winded question

    - by cop1152
    I apologize in advance for the long-winded post. I posted it all because I believe its informative and may be useful. Also, I posted my question at the end. Moments ago I was RDC to a file server in my home (from inside my home). I had opened Firefox and Googled for a manufacturers website. Immediately after clicking the link, Firefox abruptly closed. This seemed odd to me to so I checked the running processes and discovered d.exe, e.exe, and f.exe running. I Googled these processes on a different machine and found them belonging to a key-logger/screen-capturer/trojan called defender.exe, which according to the Prevx lives in c:\documents and settings\user\local settings\temp. (Prevx link http://www.prevx.com/filenames/147352809685142526-X1/DEFENDER32.EXE.html) Simultaneously, an obviously-spoofed Windows Firewall popup appeared on the server asking me to click ‘yes’ to update Windows Firewall. At this time I ended all rogue processes, emptied the temp folder, removed defender.exe from startup, and checked my registry and a few other locations. Before deleting Defender.exe I noted that it was created moments ago, just before Firefox crashed. I believe that I was ‘almost’ infected with this malware. I believe that it needed me to click the phony popup in order to complete infection because it wasn’t allowed to execute processes from the temp folder. After cleaning the machine, I restarted it and have been monitoring it for over an hour. I am debating on whether or not to restore the Windows partition (a separate physical drive from the data) or to just watch it for awhle. I should mention that, because of the specs on this machine, I do not run antivirus software, but I know it well and inspect it regularly. It is a very old Compaq with a 400mhz processer and 512mb of ram. I have a static IP and the server is in the DMZ running an FTP client and some HTTP server software. All files transferred to and stored on this machine are scanned for malware before transferring. Usually the machine only runs 19 processes and performs pretty well for its intended purpose. I posted the story so that you could be aware of a possible new piece of malware and how it acts, but I also have a question or two. First, over the last few months I have noticed that PREVX is listed at the top of most of my Google searches when researching malware, especially for new or obscure malware…and they always want you to purchase something. I don’t think they are one of the top AV companies, so it seems odd that they are always the top Google result. Does anyone have any experience with any of their products? Also, what sites do you rely on for malware researching? Recently, I have found it difficult to find good info because of HijackThis-logs and other deadend info cluttering up my searches. And lastly, besides antivirus, third-party firewall, etc, what settings would you use to lock down a machine to make it more secure in instances where a stubborn admin like myself refuses to run AV? Thanks.

  • Setting environment variables in OS X

    - by Percival Ulysses
    Despite the warning that questions that can be answered are preferred, this question is more a request for comments. I apologize for this, but I feel that it is valuable nonetheless. The problem to set up environment variables such that they are available for GUI applications has been around since the dawn of Mac OS X. The solution with ~/.MacOSX/environment.plist never satisfied me because it was not reliable, and bash style globbing wasn't available. Another solution is the use of Login Hooks with a suitable shell script, but these are deprecated. The Apple approved way for such functionality as provided by login hooks is the use of Launch Agents. I provided a launch agent that is located in /Library/LaunchAgents/: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>user.conf.launchd</string> <key>Program</key> <string>/Users/Shared/conflaunchd.sh</string> <key>ProgramArguments</key> <array> <string>~/.conf.launchd</string> </array> <key>EnableGlobbing</key> <true/> <key>RunAtLoad</key> <true/> <key>LimitLoadToSessionType</key> <array> <string>Aqua</string> <string>StandardIO</string> </array> </dict> </plist> The real work is done in the shell script /Users/Shared/conflaunchd.sh, which reads ~/.conf.launchd and feeds it to launchctl: #! /bin/bash #filename="$1" filename="$HOME/.conf.launchd" if [ ! -r "$filename" ]; then exit fi eval $(/usr/libexec/path_helper -s) while read line; do # skip lines that only contain whitespace or a comment if [ ! -n "$line" -o `expr "$line" : '#'` -gt 0 ]; then continue; fi eval launchctl $line done <"$filename" exit 0 Notice the call of path_helper to get PATH set up right. Finally, ~/.conf.launchd looks like that setenv PATH ~/Applications:"${PATH}" setenv TEXINPUTS .:~/Documents/texmf//: setenv BIBINPUTS .:~/Documents/texmf/bibtex//: setenv BSTINPUTS .:~/Documents/texmf/bibtex//: # Locale setenv LANG en_US.UTF-8 These are launchctl commands, see its manpage for further information. Works fine for me (I should mention that I'm still a Snow Leopard guy), GUI applications such as texstudio can see my local texmf tree. Things that can be improved: The shell script has a #filename="$1" in it. This is not accidental, as the file name should be feeded to the script by the launch agent as an argument, but that doesn't work. It is possible to put the script in the launch agent itsself. I am not sure how secure this solution is, as it uses eval with user provided strings. It should be mentioned that Apple intended a somewhat similar approach by putting stuff in ~/launchd.conf, but it is currently unsupported as to this date and OS (see the manpage of launchd.conf). I guess that things like globbing would not work as they do in this proposal. Finally, I would mention the sources I used as information on Launch Agents, but StackExchange doesn't let me [1], [2], [3]. Again, I am sorry that this is not a real question, I still hope it is useful.

  • Network config / gear question

    - by mcgee1234
    I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

  • Using FFmpeg in c#?

    - by daniel
    So i know its a fairly big challenge but i want to write a basic movie player/converter in c# using the FFmpeg library. However the first obstacle i need to overcome is wrapping the FFmpeg library in c#. I downloaded ffmpeg but couldn't compile it on windows, so i downloaded a precompiled version for me. Ok awesome. Then i started looking for c# wrappers. I have looked around and have found a few wrappers such as SharpFFmpeg (http://sourceforge.net/projects/sharpffmpeg/) and ffmpeg-sharp (http://code.google.com/p/ffmpeg-sharp/). First of all i wanted to use ffmpeg-sharp as its LGPL and SharpFFmpeg is GPL. However it had quite a few compile errors. Turns out it was written for the mono compiler, i tried compiling it with mon but couldn't figure out how. I then started to manually fix the compiler errors myself, but came across a few scary ones and thought i'd better leave those alone. So i gave up on ffmpeg-sharp. Then i looked at SharpFFmpeg and it looks like what i want, all the functions P/Invoked for me. However its GPL? Both the AVCodec.cs and AVFormat.cs files look like ports of avcodec.c and avformat.c which i reckon i could port myself? Then not have to worry about licencing. But i wan't to get this right before i go ahead and start coding. Should I: Write my own c++ library for interacting with ffmpeg, then have my c# program talk to the c++ library in order to play/convert videos etc. OR Port avcodec.h and avformat.h (is that all i need?) to c# by using a whole lot of DllImports and write it entirely in c#? First of all consider that i'm not great at c++ as i rarely use it but i know enough to get around. The reason i'm thinking #1 might be the better option is that most FFmpeg tutorials are in c++ and i'd also have more control over memory management that if i was to do it in c#. What do you think? Also would you happen to have any usefull links (perhaps a tutorial) for using FFmpeg? EDIT: spelling mistakes

  • C# remote web request certificate error

    - by Ben
    Hi. I am currently integrating a payment gateway into an application. Following a successful transaction the remote payment gateway posts details of the transaction back to my application (ITN). It posts to a HttpHandler that is used to read and validate the data. Part of the validation performed is a POST made by the handler to a validation service provided by the payment gateway. This effectively posts some of the original form values received back to the payment gateway to ensure they are valid. The url that I am posting back to is: "https://sandbox.payfast.co.za/eng/query/validate" and the code I am using: /// <summary> /// Posts the data back to the payment processor to validate the data received /// </summary> public static bool ValidateITNRequestData(NameValueCollection formVariables) { bool isValid = true; try { using (WebClient client = new WebClient()) { string validateUrl = (UseSandBox) ? SandboxValidateUrl : LiveValidateUrl; byte[] responseArray = client.UploadValues(validateUrl, "POST", formVariables); // get the resposne and replace the line breaks with spaces string result = Encoding.ASCII.GetString(responseArray); result = result.Replace("\r\n", " ").Replace("\r", "").Replace("\n", " "); if (result == null || !result.StartsWith("VALID")) { isValid = false; LogManager.InsertLog(LogTypeEnum.OrderError, "PayFast ITN validation failed", "The validation response was not valid."); } } } catch (Exception ex) { LogManager.InsertLog(LogTypeEnum.Unknown, "Unable to validate ITN data. Unknown exception", ex); isValid = false; } return isValid; } However, on calling WebClient.UploadValues the following exception is raised: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception) at For the sake of brevity I haven't listed the full call stack (I can do if anyone thinks it will help). The remote certificate does appear to be valid. To get around the problem I did try adding a new RemoteCertificateValidationCallback that always returned true but just ended up getting the following exception: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.ServicePointManager.set_ServerCertificateValidationCallback(RemoteCertificateValidationCallback value) at NopSolutions.NopCommerce.Payment.Methods.PayFast.PayFastPaymentProcessor.ValidateITNRequestData(NameValueCollection formVariables) The action that failed was: Demand The type of the first permission that failed was: System.Security.Permissions.SecurityPermission The Zone of the assembly that failed was: MyComputer So I am not sure this will work in medium trust? Any help would be much appreciated. Thanks Ben

  • java 7 upgrade and hibernate annotation processor error

    - by Bill Turner
    I am getting the following warning, which seems to be triggering a subsequent warning and an error. I have been googling like mad, though have not found anything that makes it clear what it is I should do to resolve this. This issue occurs when I execute an Ant build. I am trying to migrate our project to Java 7. I have changed all the source='1.6' and target="1.6" to 1.7. I did find this related article: Forward compatible Java 6 annotation processor and SupportedSourceVersion It seems to indicate that I should build the Hibernate annotation processor jar myself, compiling it with with 1.7. It does not seem I should be required to do so. The latest version of the class in question (in hibernate-validator-annotation-processor-5.0.1.Final.jar) has been compiled with 1.6. Since the code in said class refers to SourceVersion.latestSupported(), and the 1.6 of that returns only RELEASE_6, there does not seem to be a generally available solution. Here is the warning: [javac] warning: Supported source version 'RELEASE_6' from annotation processor 'org.hibernate.validator.ap.ConstraintValidationProcessor' less than -source '1.7' And, here are the subsequent warnings/error.

  • Android Packaging Problem: resources.ap_ does not exist

    - by Galip
    I am trying to fix a problem in Eclipse for like 3 hours and I haven't made any progress. Tomorrow is the customer coming to look at my app, and I have no time left. This is really frustrating! This morning when I was coding and I wanted to run my app on my device Eclipse crashed all of a sudden. 'aapt.exe has stopped working' After this Eclipse wasn't starting anymore. It froze at the splash image. I looked on the internet and tried different solutions like going back to Java SE 6 update 20, changing .ini file etc. in the end reinstalling Eclipse did the job. Shortly after that the 'aapt.exe has stopped working' returned. I found a solution by changing my projects target. 1.5, 1.6, 2.2 doesn't matter, as long as it's different than the one before. Now I get the Error generating final archive: java.io.FileNotFoundException: C:\xxx\bin\resources.ap_ does not exist error. I tried clean but that doesn't work. Deleting and automatically regenarting R.java also didn't work. I ran the same code in Netbeans with the Android plugin and there it gives me the 'aapt.exe has stopped working' again :( Please guys, how can I fix this? Edit: I think I may have found the reason. These are the error lines in the console: org.xmlpull.v1.XmlPullParserException: Binary XML file line #3: <bitmap> requires a valid src attribute at android.graphics.drawable.BitmapDrawable.inflate(BitmapDrawable.java:341) at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:779) at android.graphics.drawable.Drawable.createFromXml(Drawable.java:720) at com.android.layoutlib.bridge.ResourceHelper.getDrawable(ResourceHelper.java:150) at com.android.layoutlib.bridge.BridgeTypedArray.getDrawable(BridgeTypedArray.java:668) at android.view.View.<init>(View.java:1846) at android.view.View.<init>(View.java:1795) at android.view.ViewGroup.<init>(ViewGroup.java:282) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) [2011-01-17 16:37:20 - gegevens.xml] Unable to resolve drawable "com.android.layoutlib.utils.ResourceValue@267e33de" in attribute "background" The file it's talking about is 'bg.png'.

  • PHP SimpleXML recursive function to list children and attibutes

    - by Phill Pafford
    I need some help on the SimpleXML calls for a recursive function that lists the elements name and attributes. Making a XML config file system but each script will have it's own config file as well as a new naming convention. So what I need is an easy way to map out all the elements that have attributes, so like in example 1 I need a simple way to call all the processes but I don't know how to do this without hard coding the elements name is the function call. Is there a way to recursively call a function to match a child element name? I did see the xpath functionality but I don't see how to use this for attributes. Any ideas? Also does the XML in the examples look correct? can I structure my XML like this? Example 1: <application> <processes> <process id="123" name="run batch A" /> <process id="122" name="run batch B" /> <process id="129" name="run batch C" /> </processes> <connections> <databases> <database usr="test" pss="test" hst="test" dbn="test" /> </databases> <shells> <ssh usr="test" pss="test" hst="test-2" /> <ssh usr="test" pss="test" hst="test-1" /> </shells> </connections> </application> Example 2: <config> <queues> <queue id="1" name="test" /> <queue id="2" name="production" /> <queue id="3" name="error" /> </queues> </config> Pseudo code: // Would return matching process id getProcess($process_id) { return the process attributes as array that are in the XML } // Would return matching DBN (database name) getDatabase($database_name) { return the database attributes as array that are in the XML } // Would return matching SSH Host getSSHHost($ssh_host) { return the ssh attributes as array that are in the XML } // Would return matching SSH User getSSHUser($ssh_user) { return the ssh attributes as array that are in the XML } // Would return matching Queue getQueue($queue_id) { return the queue attributes as array that are in the XML } EDIT: Can I pass two parms? on the first method you have suggested @Gordon public function findProcessById($id, $name) { $attr = false; $el = $this->xml->xpath("//process[@id='$id']"); // How do I also filter by the name? if($el && count($el) === 1) { $attr = (array) $el[0]->attributes(); $attr = $attr['@attributes']; } return $attr; }

  • [AS3/C#] Byte encryption ( DES-CBC zero pad )

    - by mark_dj
    Hi there, Currently writing my own AMF TcpSocketServer. Everything works good so far i can send and recieve objects and i use some serialization/deserialization code. Now i started working on the encryption code and i am not so familiar with this stuff. I work with bytes , is DES-CBC a good way to encrypt this stuff? Or are there other more performant/secure ways to send my data? Note that performance is a must :). When i call: ReadAmf3Object with the decrypter specified i get an: InvalidOperationException thrown by my ReadAmf3Object function when i read out the first byte the Amf3TypeCode isn't specified ( they range from 0 to 16 i believe (Bool, String, Int, DateTime, etc) ). I got Typecodes varying from 97 to 254? Anyone knows whats going wrong? I think it has something to do with the encryption part. Since the deserializer works fine w/o the encryption. I am using the right padding/mode/key? I used: http://code.google.com/p/as3crypto/ as as3 encryption/decryption library. And i wrote an Async tcp server with some abuse of the threadpool ;) Anyway here some code: C# crypter initalization code System.Security.Cryptography.DESCryptoServiceProvider crypter = new DESCryptoServiceProvider(); crypter.Padding = PaddingMode.Zeros; crypter.Mode = CipherMode.CBC; crypter.Key = Encoding.ASCII.GetBytes("TESTTEST"); AS3 private static var _KEY:ByteArray = Hex.toArray(Hex.fromString("TESTTEST")); private static var _TYPE:String = "des-cbc"; public static function encrypt(array:ByteArray):ByteArray { var pad:IPad = new NullPad; var mode:ICipher = Crypto.getCipher(_TYPE, _KEY, pad); pad.setBlockSize(mode.getBlockSize()); mode.encrypt(array); return array; } public static function decrypt(array:ByteArray):ByteArray { var pad:IPad = new NullPad; var mode:ICipher = Crypto.getCipher(_TYPE, _KEY, pad); pad.setBlockSize(mode.getBlockSize()); mode.decrypt(array); return array; } C# read/unserialize/decrypt code public override object Read(int length) { object d; using (MemoryStream stream = new MemoryStream()) { stream.Write(this._readBuffer, 0, length); stream.Position = 0; if (this.Decrypter != null) { using (CryptoStream c = new CryptoStream(stream, this.Decrypter, CryptoStreamMode.Read)) using (AmfReader reader = new AmfReader(c)) { d = reader.ReadAmf3Object(); } } else { using (AmfReader reader = new AmfReader(stream)) { d = reader.ReadAmf3Object(); } } } return d; }

  • Access Violation Using memcpy or Assignment to an Array in a Struct

    - by Synetech inc.
    Hi, I wrote a program last night that worked just fine but when I refactored it today to make it more extensible, I ended up with a problem. The original version had a hard-coded array of bytes. After some processing, some bytes were written into the array and then some more processing was done. To avoid hard-coding the pattern, I put the array in a structure so that I could add some related data and create an array of them. However now, I cannot write to the array in the structure. Here’s a pseudo-code example: main() { char pattern[]="\x32\x33\x12\x13\xba\xbb"; PrintData(pattern); pattern[2]='\x65'; PrintData(pattern); } That one works but this one does not: struct ENTRY { char* pattern; int somenum; }; main() { ENTRY Entries[] = { {"\x32\x33\x12\x13\xba\xbb\x9a\xbc", 44} , {"\x12\x34\x56\x78", 555} }; PrintData(Entries[0].pattern); Entries[0].pattern[2]='\x65'; //0xC0000005 exception!!! :( PrintData(Entries[0].pattern); } The second version causes an access violation exception on the assignment. I’m sure it’s because the second version allocates memory differently, but I’m starting to get a headache trying to figure out what’s what or how to get fix this. (I’m currently working around it by dynamically allocating a buffer of the same size as the pattern array, copying the pattern to the new buffer, making the changes to the buffer, using the buffer in the place of the pattern array, and then trying to remember to free the—temporary—buffer.) (Specifically, the original version cast the pattern array—+offset—to a DWORD* and assigned a DWORD constant to it to overwrite the four target bytes. The new version cannot do that since the length of the source is unknown—may not be four bytes—so it uses memcpy instead. I’ve checked and re-checked and have made sure that the pointers to memcpy are correct, but I still get an access violation. I use memcpy instead of str(n)cpy because I am using plain chars (as an array of bytes), not Unicode chars and ignoring the null-terminator. Using an assignment as above causes the same problem.) Any ideas? Thanks a lot.

  • WPF-Prism CanExecute method not being called

    - by nareshbhatia
    I am coding a simple login UserControl with two TextBoxes (Username and Password) and a Login button. I want the Login button to be enabled only when the username and password fields are filled in. I am using Prism and MVVM. The LoginViewModel contains a property called LoginCommand that is bound to the Login button. I have a CanLoginExecute() method in my ViewModel but it fires only when the application comes up and then never again. So the Login button is never enabled. What am I missing? Here's my xaml: <TextBox x:Name="username" Text="{Binding Path=Username, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" /> <TextBox x:Name="password" Text="{Binding Path=Password, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" /> <Button Content="Login" cmnd:Click.Command="{Binding LoginCommand}" /> Here's my ViewModel class LoginViewModel : IDataErrorInfo, INotifyPropertyChanged { public LoginViewModel() { this.LoginCommand = new DelegateCommand<object>( this.LoginExecute, this.CanLoginExecute); } private Boolean CanLoginExecute(object dummyObject) { return (string.IsNullOrEmpty(Username) || string.IsNullOrEmpty(Password)) ? false : true; } private void LoginExecute(object dummyObject) { if (CheckCredentials(Username, Password)) { .... } } #region IDataErrorInfo Members public string Error { get { throw new NotImplementedException(); } } public string this[string columnName] { get { string result = null; if (columnName == "Username") { if (string.IsNullOrEmpty(Username)) result = "Please enter a username"; } else if (columnName == "Password") { if (string.IsNullOrEmpty(Password)) result = "Please enter a password"; } return result; } } #endregion // IDataErrorInfo Members #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; void OnPropertyChanged(string propertyName) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } #endregion // INotifyPropertyChanged Members #region Properties private String _username; public String Username { get { return _username; } set { if (value == _username) return; _username = value; this.OnPropertyChanged("Username"); } } private String _password; public String Password { get { return _password; } set { if (value == _password) return; _password = value; this.OnPropertyChanged("Password"); } } public ICommand LoginCommand { get; private set; } #endregion // Properties }

  • Single Sign On for a Web App

    - by Jeremy Goodell
    I have been trying to understand how this problem is solved for over a month now. I really need to come up with a general approach that works -- I'm basically the only resource who can do it. I have a theory, but I'm just not sure it's the easiest (or correct) approach and I haven't been able to find any information to support my ideas. Here's the scenario: 1) You have a complex web application that offers secure content on a subscription basis. 2) Users are required to log in to your application with user name and password. 3) You sell to large corporations, which already have a corporate authentication technology (for example, Active Directory). 4) You would like to integrate with the corporate authentication mechanism to allow their users to log onto your Web App without having to enter their user name and password. Now, any solution you come up with will have to provide a mechanism for: adding new users removing users changing user information allowing users to log in Ideally, all these would happen "automagically" when the corporate customer made the corresponding changes to their own authentication. Now, I have a theory that the way to do this (at least for Active Directory) would be for me to write a client-side app that integrates with the customer's Active Directory to track the targeted changes, and then communicate those changes to my Web App. I think that if this communication were done via Web Services offered by my web app, then it would maintain an unhackable level of security, which would obviously be a requirement for these corporate customers. I've found some information about a Microsoft product called Active Directory Federation Service (ADFS) which may or may not be the right approach for me. It seems to be a bit bulky and have some requirements that might not work for all customers. For other existing ID scenarios (like Athens and Shibboleth), I don't think a client application is necessary. It's probably just a matter of tying into the existing ID services. I would appreciate any advice anyone has on anything I've mentioned here. In particular, if you can tell me if my theory is correct about providing a client-side app that communicates with server-side Web Services, or if I'm totally going in the wrong direction. Also, if you could point me at any web sites or articles that explain how to do this, I'd really appreciate it. My research has not turned up much so far. Finally, if you could let me know of any Web applications that currently offer this service (particularly as tied to a corporate Active Directory), I would be very grateful. I am wondering if other B2B Web app's like salesforce.com, or hoovers.com offer a similar service for their corporate customers. I hate being in the dark and would greatly appreciate any light you can shed ... Jeremy

  • Send User-Agent through CONNECT and POST with WinHTTP?

    - by Duncan Bayne
    I'm trying to POST to a secure site using WinHttp, and running into a problem where the User-Agent header isn't being sent along with the CONNECT. I am using a lightly-modified code sample from MSDN: HINTERNET hHttpSession = NULL; HINTERNET hConnect = NULL; HINTERNET hRequest = NULL; WINHTTP_AUTOPROXY_OPTIONS AutoProxyOptions; WINHTTP_PROXY_INFO ProxyInfo; DWORD cbProxyInfoSize = sizeof(ProxyInfo); ZeroMemory( &AutoProxyOptions, sizeof(AutoProxyOptions) ); ZeroMemory( &ProxyInfo, sizeof(ProxyInfo) ); hHttpSession = WinHttpOpen(L"WinHTTP AutoProxy Sample/1.0", WINHTTP_ACCESS_TYPE_NO_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0); if(!hHttpSession) goto Exit; hConnect = WinHttpConnect( hHttpSession, L"server.com", INTERNET_DEFAULT_HTTPS_PORT, 0 ); if( !hConnect ) goto Exit; hRequest = WinHttpOpenRequest(hConnect, L"POST", L"/resource", NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE ); if( !hRequest ) goto Exit; WINHTTP_PROXY_INFO proxyInfo; proxyInfo.dwAccessType = WINHTTP_ACCESS_TYPE_NAMED_PROXY; proxyInfo.lpszProxy = L"192.168.1.2:3199"; proxyInfo.lpszProxyBypass = L""; WinHttpSetOption(hHttpSession, WINHTTP_OPTION_PROXY, &proxyInfo, sizeof(proxyInfo)); WinHttpSetCredentials(hRequest, WINHTTP_AUTH_TARGET_PROXY, WINHTTP_AUTH_SCHEME_BASIC, L"proxyuser", L"proxypass", NULL); if( !WinHttpSendRequest(hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, "content", 7, 7, 0)) { goto Exit; } if(!WinHttpReceiveResponse(hRequest, NULL)) goto Exit; /* handle result */ Exit: if( ProxyInfo.lpszProxy != NULL ) GlobalFree(ProxyInfo.lpszProxy); if( ProxyInfo.lpszProxyBypass != NULL ) GlobalFree( ProxyInfo.lpszProxyBypass ); if( hRequest != NULL ) WinHttpCloseHandle( hRequest ); if( hConnect != NULL ) WinHttpCloseHandle( hConnect ); if( hHttpSession != NULL ) WinHttpCloseHandle( hHttpSession ); What this does is connect to my server through an authenticated proxy at 192.168.1.2:3199, and make a POST. This works, but when I examine the proxy logs the User-Agent string ("WinHTTP AutoProxy Sample/1.0") is not being sent as part of the CONNECT. It is however sent as part of the POST. Could someone please tell me how I can change this code to have the User-Agent header sent during both the CONNECT and POST? Edited to add: we are observing this problem only on Windows 7. If we run the same code on a Windows Vista box, we can see the User-Agent header being sent on CONNECT.

  • Log4r : logger inheritance, yaml configuration, alternatives ?

    - by devlearn
    Hello, I'm pretty new to ruby environments and I was looking for a nice logging framework to use it my ruby and rails applications. In my previous experiences I have successfully used log4j and log4p (the perl port) and was expecting the same level of usability (and maturity) with log4r. However I must say that there are a number of things that are not clear at all in the log4r framework. 1 Logger Inheritance The logger inheritance does not seem to be managed at all ! If I declare a logger named 'myapp' and then try to get a logger name 'myapp::engine', the lookup will end with a NameError. I would expect that the framework returns the root logger according to the naming scheme and to use the 'myapp' logger. Q1 : Of course I can work around this and manage the names by myself with a lookup method, however is there a cleaner way to do this without any extra coding ? 2 YAML configuration Second thing that confuses me is the yaml configuration. On the log4r site there are literally no information about this system, the doc links forward to missing pages, so all the info I can find about is contained in the examples directory of the gem. I was pretty confused with the fact that the yaml configuration must contain the pre_config section, and that I need to define my own levels. If I remove the pre_config secion, or replace all the “custom” levels by the standard ones ( debug, info, warn, fatal ) , the example will throw the following error : log4r/yamlconfigurator.rb:68:in `decode_yaml': Log level must be in 0..7 (ArgumentError) So there seems to be no way of using a simple file where we only declare the loggers and appenders for the framework. Q2 : I realy think that I missed something and that must be a way of providing a simple yaml conf file. Do you have any examples of such an usage ? 3 Variables substitution in XML file Q3 : The Yaml configuration system seems to provide such a feature however I was unable to find a similar feature with XML files. Any ideas ? 4 Alternatives ? I must say that I'm very disappointed by the feature level and the maturity of log4r compared to the log4j and other log4j ports. I run into this framework with a solid background of logging APIs in other languages and find myself working around in all kinds just to make 'basic things' running in a “real world application”. By that I mean a complex application composed of several gems, console/scripting apps, and a rails web front end where the configuration must be mutualized and where we make intensive usage of namespaces and inheritance. I've run several searches in order to find something more suitable or mature, but did not find anything similar. Q4 : Do you guys know any (serious) alternatives to log4r framework that could be used in a enterprise class app ? Thanks reading all of this ! I'd really appreciate any pointers, Kind Regards,

  • surfaceview + glsurfaceview + framelayout

    - by pohtzeyun
    Hi, I'm new at this (java and opengl) so please bear with me if the answer to the question is simple. :) I'm trying to get a camera preview screen with the ability to display 3d objects simultaneously. Having gone through the samples at the api demos, I thought combining the code for the the examples at the api demo would suffice. But somehow its not working. The forces me to shut down upon startup and the error is mentioned as null pointer exception. Could someone share with me where did I go wrong and how to proceed from there. How I did the combination for the code is as shown below: myoverview.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <android.opengl.GLSurfaceView android:id="@+id/cubes" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <SurfaceView android:id="@+id/camera" android:layout_width="fill_parent" android:layout_height="fill_parent"/> </FrameLayout> myoverview.java import android.app.Activity; import android.os.Bundle; import android.view.SurfaceView; import android.view.Window; public class MyOverView extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Hide the window title. requestWindowFeature(Window.FEATURE_NO_TITLE); // camera view as the background SurfaceView cameraView = (SurfaceView) findViewById(R.id.camera); cameraView = new CameraView(this); // visual of both cubes GLSurfaceView cubesView = (GLSurfaceView) findViewById(R.id.cubes); cubesView = new GLSurfaceView(this); cubesView.setRenderer(new CubeRenderer(false)); // set view setContentView(R.layout.myoverview); } } GLSurfaceView.java import android.content.Context; class GLSurfaceView extends android.opengl.GLSurfaceView { public GLSurfaceView(Context context) { super(context); } } NOTE : I didnt list the rest of the files as they are just copies of the api demos. The cameraView refers to the camerapreview.java example and the CubeRenderer refers to the CubeRenderer.java and Cube.java example. Any help would be appreciated as I've been stuck at this for a couple of days :p Thanks Sorry, didnt realise that the coding was out of place due to formatting mistakes. :p
