  • Generate TFTP Content on the fly?

    - by andyortlieb
    I know this isn't the purpose of TFTP, but I'm working in an environment where a lot of different types of devices pull provisioning info from a TFTP server. What I'm developing is a provisioning system that tracks and maintains device configurations, and I would like to have the requested files generated on the fly, much like you could do with any web application. Yes some of these devices can support HTTP for provisioning, but not all of them do, and we want things to be consistent. Are there any TFTP daemons that can provide something analogous to CGI?

  • OpenVPN on ec2 bridged mode connects but no Ping, DNS or forwarding

    - by michael
    I am trying to use OpenVPN to access the internet over a secure connection. I have openVPN configured and running on Amazon EC2 in bridge mode with client certs. I can successfully connect from the client, but I cannot get access to the internet or ping anything from the client I checked the following and everything seems to shows a successful connection between the vpn client/server and UDP traffic on 1194 [server] sudo tcpdump -i eth0 udp port 1194 (shows UDP traffic after establishing connection) [server] sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT all -- anywhere anywhere Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination [server] sudo iptables -L -t nat Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- ip-W-X-Y-0.us-west-1.compute.internal/24 anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination [server] openvpn.log Wed Oct 19 03:11:26 2011 localhost/a.b.c.d:61905 [localhost] Inactivity timeout (--ping-restart), restarting Wed Oct 19 03:11:26 2011 localhost/a.b.c.d:61905 SIGUSR1[soft,ping-restart] received, client-instance restarting Wed Oct 19 03:41:31 2011 MULTI: multi_create_instance called Wed Oct 19 03:41:31 2011 a.b.c.d:57889 Re-using SSL/TLS context Wed Oct 19 03:41:31 2011 a.b.c.d:57889 LZO compression initialized Wed Oct 19 03:41:31 2011 a.b.c.d:57889 Control Channel MTU parms [ L:1574 D:166 EF:66 EB:0 ET:0 EL:0 ] Wed Oct 19 03:41:31 2011 a.b.c.d:57889 Data Channel MTU parms [ L:1574 D:1450 EF:42 EB:135 ET:32 EL:0 AF:3/1 ] Wed Oct 19 03:41:31 2011 a.b.c.d:57889 Local Options hash (VER=V4): '360696c5' Wed Oct 19 03:41:31 2011 a.b.c.d:57889 Expected Remote Options hash (VER=V4): '13a273ba' Wed Oct 19 03:41:31 2011 a.b.c.d:57889 TLS: Initial packet from [AF_INET]a.b.c.d:57889, sid=dd886604 ab6ebb38 Wed Oct 19 03:41:35 2011 a.b.c.d:57889 VERIFY OK: depth=1, /C=US/ST=CA/L=SanFrancisco/O=EXAMPLE/CN=EXAMPLE_CA/[email protected] Wed Oct 19 03:41:35 2011 a.b.c.d:57889 VERIFY OK: depth=0, /C=US/ST=CA/L=SanFrancisco/O=EXAMPLE/CN=localhost/[email protected] Wed Oct 19 03:41:37 2011 a.b.c.d:57889 Data Channel Encrypt: Cipher 'BF-CBC' initialized with 128 bit key Wed Oct 19 03:41:37 2011 a.b.c.d:57889 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Wed Oct 19 03:41:37 2011 a.b.c.d:57889 Data Channel Decrypt: Cipher 'BF-CBC' initialized with 128 bit key Wed Oct 19 03:41:37 2011 a.b.c.d:57889 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Wed Oct 19 03:41:37 2011 a.b.c.d:57889 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 1024 bit RSA Wed Oct 19 03:41:37 2011 a.b.c.d:57889 [localhost] Peer Connection Initiated with [AF_INET]a.b.c.d:57889 Wed Oct 19 03:41:39 2011 localhost/a.b.c.d:57889 PUSH: Received control message: 'PUSH_REQUEST' Wed Oct 19 03:41:39 2011 localhost/a.b.c.d:57889 SENT CONTROL [localhost]: 'PUSH_REPLY,redirect-gateway def1 bypass-dhcp,route-gateway W.X.Y.Z,ping 10,ping-restart 120,ifconfig W.X.Y.Z 255.255.255.0' (status=1) Wed Oct 19 03:41:40 2011 localhost/a.b.c.d:57889 MULTI: Learn: (IPV6) -> localhost/a.b.c.d:57889 [client] tracert google.com Tracing route to google.com [74.125.71.104] over a maximum of 30 hops: 1 347 ms 349 ms 348 ms PC [w.X.Y.Z] 2 * * * Request timed out.

  • Video Card needs additional mounting support

    - by Sean
    We are creating a fairly decent system with crossfire. The issue we are having is apparently the video cards are physically to heavy to be supported purely by the motherboard and case mounts. Whenever we have the case horizontal everything works fine however when we bring the case upright the computer stops working. Relevant Info: Video Cards (2) - Sapphire 5870 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102856) MotherBoard - Asus M4A79T Deluxe Case - CoolerMaster 922 HAF To me it looks as if an additional support bracket that could hold up the end of the card would be required (included with the viideo cards!!!) Does anyone have any experience with this.

  • Snort: not logging anything

    - by ethrbunny
    My site seems to be the target of quite a bit of probing over the last few months. In an attempt to get a better handle on this I installed SNORT on one of the machines that has external exposure. Something must not be installed correctly as I see lots of probing in /var/log/messages but snort isn't logging anything. System: CentOS 6.2 (32 bit) Snort: (latest build and rules) Snort configured from this v excellent site: http://nachum234.no-ip.org/security/snort/001-snort-installation-on-centos-6-2/ snort running as daemon: /usr/local/bin/snort -d -D -i bond0 -u snort -g snort -c /etc/snort.d/snort.conf -l /var/log/snort The snort.log file is empty despite hundreds (or more) failed login attempts from individual IP addresses. Maybe Im missing the purpose of SNORT? I was hoping it would log this sort of info.

  • Is there a Windows equivalent of Unix 'CPU steal time'?

    - by Steffen Opel
    In order to assess performance monitoring accuracy on virtualization platforms, the CPU steal time has become an increasingly relevant metric - see EC2 monitoring: the case of stolen CPU for an instructive summary in the context of Amazon EC2 and IBM's paper on CPU time accounting for a more in-depth technical explanation (including illustrations) of the concept: Steal time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor. Accordingly, it is exposed in most related Unix/Linux monitoring tools nowadays - see e.g. columns %steal or st in sar or top: st -- Steal Time The amount of CPU 'stolen' from this virtual machine by the hypervisor for other tasks (such as running another virtual machine). I've been unable to figure out how to capture the same metric on Windows though, is this possible already? (Ideally for the Windows 2008 Server R2 AMIs on EC2 and via a respective Windows Performance Counters of course.)

  • How to create a very simple external FastCGI configuration in apache?

    - by Thiado de Arruda
    I have an externally started FastCGI application that listens on socket '/tmp/foo.sock' and a directory of static files in '/srv/static'. Apache has all needed permissions on the socket and the directories. What I need : All requests starting with '/static' should be handled by apache using the contents of '/srv/static'. All other requests should be handled by the FastCGI application. Here is my current virtual host configuration: <VirtualHost *:80> ServerAdmin [email protected] ServerName www.foo.com ServerAlias foo.com Alias /static /srv/static FastCgiExternalServer /* -socket /tmp/foo.sock ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /var/log/apache2/access.log combined </VirtualHost> Even though this seems simple, its giving me quite the headache. According to http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html#FastCgiExternalServer the first parameter to 'FastCgiExternalServer' should be a 'filename' that when matched will cause apache to delegate the request to the external FastCGI app. What am I missing here?

  • Virtualbox two networks slow

    - by Petr Marek
    I am running an Ubuntu server guest on Win 7 guest, and am running a webrick server (RoR dev). If I have just a host-only network, everything works fine and the browser response is instant. However, if I add a second network (NAT), so that the server can connect to the internet (for various updates etc.), the host-to-guest access gets really slow. I can't use the bridge connection. I am using the port 3000 (RoR Webrick server) and connecting to the guest via internet browser on this port (eg http://192.168.56.102:3000). Any idea, what could be causing this? If I ping the IP from host console, I get < 0ms. Here are the settings (relevant info is in english; Povoleno vše is Everything is allowed):

  • Long file path returning 404 for "hello.htm"

    - by Adam Kane
    Hello, I have a long file path that works on my server, but a simliar path returns a 404 error when it is on my clients (IIS6) server (http://ddmat.com/). Here's the functioning file path on my server: http://www.forgefx.com/projects/ddmat/install/Application Files/McCurdys_1_0_0_0/Content/FBX/CCAE1B33/Roof-sectionB-02.fbm/hello.htm My guesses: Maybe the file path is too long? Maybe the ".fbm" in the directory path is invalid? Sorry for the vauge problem description. Please let me know what additional info I can provide that'd be helpful. Update: The problem happens even in short paths, with no spaces: http://www.myserver/test.folder/hell.htm Thanks, Adam

  • ERROR 0x8007007A when trying to schedule a task

    - by Paul Hollingsworth
    I am getting the error "The data area passed to a system call is too small. (Exception from HRESULT: 0x8007007A)" when trying to create a scheduled task on a particular windows machine. The problem description is identical to that described in this Microsoft KB article I followed their steps to resolve: Stopped the task scheduler service (right-clicked "Task Scheduler" in the Services window from Control Panel and selected "Stop"). Restarted the task scheduler service Waited 15 minutes tried to schedule the task. But the error is persisting. To give more context of how we are creating these scheduled tasks, they are actually generated automatically from a configuration script (we run the script each time we wish to make a change). Each time this happens, it deletes all of the existing tasks and creates new ones. I don't know what else to try.... but surely there is some way to "reset" the task scheduler... How can I stop this error from happening.

  • LDAP query on linux against AD returns groups with no members

    - by SethG
    I am using LDAP+kerberos to authenticate against Active Directory on Windows 2003 R2. My krb5.conf and ldap.conf appear to be correct (according to pretty much every sample I found on the 'net). I can login to the host with both password and ssh keys. When I run getent passwd, all my ldap user accounts are listed with all the important attributes. When I run getent group, all the ldap groups and their gid's are listed, but no group members. If I run ldapsearch and filter on any group, the members are all listed with the "member" attribute. So the data is there for the taking, it's just not being parsed properly. It would appear that I simply am using an incorrect mapping in ldap.conf, but I can't see it. I've tried several variations and all give the same result. Here is my current ldap.conf: host <ad-host1-ip> <ad-host2-ip> base dc=my,dc=full,dc=dn uri ldap://<ad-host1> ldap://<ad-host2> ldap_version 3 binddn <mybinddn> bindpw <mybindpw> scope sub bind_policy hard nss_reconnect_tries 3 nss_reconnect_sleeptime 1 nss_reconnect_maxsleeptime 8 nss_reconnect_maxconntries 3 nss_map_objectclass posixAccount User nss_map_objectclass posixGroup Group nss_map_attribute uid sAMAccountName nss_map_attribute gidNumber msSFU30GidNumber nss_map_attribute uidNumber msSFU30UidNumber nss_map_attribute cn cn nss_map_attribute gecos displayName nss_map_attribute homeDirectory msSFU30HomeDirectory nss_map_attribute loginShell msSFU30LoginShell nss_map_attribute uniqueMember member pam_filter objectcategory=User pam_login_attribute sAMAccountName pam_member_attribute member pam_password ad Here's the kicker: this config works 100% fine on a different linux box with a different distro. It does not work on the distro I am planning on switching to. I have installed from source the versions of pam_ldap and nss_ldap on the new box to match the old box, which fixed another problem I was having with this setup. Other relevant info is the original AD box was Windows 2003. It's mirror died a horrible hardware death so I'm trying to add two more 2003-R2 servers to the mirror tree and ultimately drop the old 2003 box. The new R2 boxes appear to have joined the DC forest properly. What do I need to do to get groups working? I've exhausted all the resources I could find and need a different angle. Any input is appreciated. Status update, 7/31/09 I have managed to tweak my config file to get full info from the AD and performance is nice and snappy. I replaced the back-rev'd copies of pam_ldap and nss_ldap with the current ones for the distro I'm using, so it's back to a standard out-of-the-box install. Here's my current config: host <ad-host1-ip> <ad-host2-ip> base dc=my,dc=full,dc=dn uri ldap://<ad-host1> ldap://<ad-host2> ldap_version 3 binddn <mybinddn> bindpw <mybindpw> scope sub bind_policy soft nss_reconnect_tries 3 nss_reconnect_sleeptime 1 nss_reconnect_maxsleeptime 8 nss_reconnect_maxconntries 3 nss_connect_policy oneshot referrals no nss_map_objectclass posixAccount User nss_map_objectclass posixGroup Group nss_map_attribute uid sAMAccountName nss_map_attribute gidNumber msSFU30GidNumber nss_map_attribute uidNumber msSFU30UidNumber nss_map_attribute cn cn nss_map_attribute gecos displayName nss_map_attribute homeDirectory msSFU30HomeDirectory nss_map_attribute loginShell msSFU30LoginShell nss_map_attribute uniqueMember member pam_filter objectcategory=CN=Person,CN=Schema,CN=Configuration,DC=w2k,DC=cis,DC=ksu,DC=edu pam_login_attribute sAMAccountName pam_member_attribute member pam_password ad ssl off tls_checkpeer no sasl_secprops maxssf=0 The remaining problem now is when you run the groups command, not all subscribed groups are listed. Some are (one or two), but not all. Group memberships are still honored, such as file and printer access. getent group foo still shows that the user is a member of group foo. So it appears to be a presentation bug, and does not interfere with normal operation. It also appears that some (I have not determined exactly how many) group searches do not resolve correctly, even though the group is listed. eg, when you run "getent group bar", nothing is returned, but if you run "getent group|grep bar" or "getent group|grep <bar_gid>" you can see that it indeed listed and your group name and gid are correct. This still seems like an LDAP search or mapping error, but I can't figure out what it is. I'm a heckuva lot closer than earlier in the week, but I'd really like to get this last detail ironed out.

  • IPv6 local address in hosts file

    - by Dan
    I have set up a local domain on my Apache server. Then I added the following line in my /etc/hosts file ::1 exampledomain.local After I trying to navigate to it, (I tried Firefox and Chromium) I got a server not found error. Then I tried ping6 and it worked: dan@danny:~$ ping6 exampledomain.local PING exampledomain.local(exampledomain.local) 56 data bytes 64 bytes from exampledomain.local: icmp_seq=1 ttl=64 time=0.032 ms If I replace ::1 with 127.0.0.1 in my hosts file, it works fine. I'm not sure if this is relevant but this is my Virtual Host configuration in Apache2: <VirtualHost *:80> ServerAlias exampledomain.local DocumentRoot /home/dan/sites/exampledomain <Directory /home/dan/sites/exampledomain> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/exampledomain-error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

  • Can Linux file permissions be fooled?

    - by puk
    I came across this example today and I wondered how reliable Linux file permissions are for hiding information $ mkdir fooledYa $ mkdir fooledYa/ohReally $ chmod 0300 fooledYa/ $ cd fooledYa/ $ ls >>> ls: cannot open directory .: Permission denied $ cd ohReally $ ls -ld . >>> drwxrwxr-x 2 user user 4096 2012-05-30 17:42 . Now I am not a Linux OS expert, so I have no doubt that someone out there will explain to me that this is perfectly logical from the OS's point of view. However, my question still stands, is it possible to fool, not hack, the OS into letting you view files/inode info which you are not supposed to? What if I had issued the command chmod 0000 fooledYa, could an experienced programmer find some round about way to read a file such as fooledYa/ohReally/foo.txt?

  • Tomcat cookies not working via my ProxyPass VirtualHost

    - by John
    Hi there. I'm having some issues with getting cookies to work when using a ProxyPass to redirect traffic on port 80 to a web-application hosted via Tomcat. My motivation for enabling cookies is to get rid of the "jsessionid=" parameter that is appended to the URLs. I've enabled cookies in my context.xml in META-INF/ for my web application. When I access the webapplication via http://url:8080/webapp it works as expected, the jsessionid parameter is not visible in the URL, instead it's stored in a cookie. When accessing my website via an apache2 virtualhost the cookies doesn't seem to work because now "jsessionid" is being appended to the URLs. How can I solve this issue? Here's my VHost configuration: <VirtualHost *:80 ServerName somedomain.no ServerAlias www.somedomain.no <Proxy * Order deny,allow Allow from all </Proxy ProxyPreserveHost Off ProxyPass / http://localhost:8080/webapp/ ProxyPassReverse / http://localhost:8080/webapp/ ErrorLog /var/log/apache2/somedomain.no.error.log CustomLog /var/log/apache2/somedomain.no.access.log combined </VirtualHost

  • How to open ports on modem for better torrent performance

    - by Mehper C. Palavuzlar
    I've been using utorrent to download and upload torrents for a long time. Recently someone told me that I need to open port(s) for utorrent from my modem settings for better downloading and uploading performance. Is it true? If yes, how can I do that? My utorrent version: 2.0 and the port used for incoming connections: 61829. My modem: Yaksu S200 ADSL router modem and I can reach its settings via web interface. I looked at the settings but they seem a bit complicated to me. Other info you may need to know: I have dynamic IP. I'm using Win7 x64.

  • Linux - Only first virtual interface can ping external gateway

    - by husvar
    I created 3 virtual interfaces with different mac addresses all linked to the same physical interface. I see that they successfully arp for the gw and they can ping (the request is coming in the packet capture in wireshark). However the ping utility does not count the responses. Does anyone knows the issue? I am running Ubuntu 14.04 in a VmWare. root@ubuntu:~# ip link sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether 00:0c:29:bc:fc:8b brd ff:ff:ff:ff:ff:ff root@ubuntu:~# ip addr sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:bc:fc:8b brd ff:ff:ff:ff:ff:ff inet6 fe80::20c:29ff:febc:fc8b/64 scope link valid_lft forever preferred_lft forever root@ubuntu:~# ip route sh root@ubuntu:~# ip link add link eth0 eth0.1 addr 00:00:00:00:00:11 type macvlan root@ubuntu:~# ip link add link eth0 eth0.2 addr 00:00:00:00:00:22 type macvlan root@ubuntu:~# ip link add link eth0 eth0.3 addr 00:00:00:00:00:33 type macvlan root@ubuntu:~# ip -4 link sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether 00:0c:29:bc:fc:8b brd ff:ff:ff:ff:ff:ff 18: eth0.1@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/ether 00:00:00:00:00:11 brd ff:ff:ff:ff:ff:ff 19: eth0.2@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/ether 00:00:00:00:00:22 brd ff:ff:ff:ff:ff:ff 20: eth0.3@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/ether 00:00:00:00:00:33 brd ff:ff:ff:ff:ff:ff root@ubuntu:~# ip -4 addr sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever root@ubuntu:~# ip -4 route sh root@ubuntu:~# dhclient -v eth0.1 Internet Systems Consortium DHCP Client 4.2.4 Copyright 2004-2012 Internet Systems Consortium.

  • Can VMWare Workstation 7.x and Sun VirtualBox 3.1.x co-exist on the same Windows7 64bit HOST togethe

    - by Heston T. Holtmann
    BACKGROUND INFO: My Old Workstation Host: 32bit Ubuntu 9.04 running Sun Virtual Box 3.x hosting Windows-XP VM Guest for Windows Software app development (VS2008, etc) My New Workstation Host: 64bit Windows7 running VMWare Workstation 7 to host 32bit Ubuntu 9.10 for linux project work. NEEDS: I need to get my original Sun-VBox Windows-XP Guest running on my new Windows7 Workstation either imported into VMWare or running on the Windows version of Sun-Virtual box (I have the VM-Guest Backed up and copied to the new computer data drive. PROBLEM: I don't need to run VM's from Both Virtual-Machine Software packages at the same time... but I do need to run some older Virtual-Machines from Sun-Virtualbox on the same 64bit Windows7 host until I can migrate those VM's to VMWare. Before switching from Linux HOST to Windows HOST, I ensured to export the VirtualBox VM to an OVF "appliance" with intentions of importing into VMWare Workstation 7.. but VMWare gives me an error stating it can't import it QUESTION: Will installing Sun Virtual Box bash or interfere with my VMWare installtion?

  • How can I rewrite / redirect URL's in Glassfish V3?

    - by Jin Liew
    Hi, I'd like to simplify the URL's to access a Glassfish V3 application by removing file extensions and otherwise shortening URL's. I've already set my application as the default application, so that there is no need to include the context root in the URL. I'd like to: * Remove file extensions * Shorten the URL to files deep in the folder structure I'd like to do this using pattern matching rather than on a per file basis (Site is small at the moment but will change frequently and grow). Some examples of what I'd like to do: * foo.com/bar.html - foo.com/bar * foo.com/folder1/folder2/bar2.html - foo.com/bar2 Any help would be greatly appreciated. Thanks. Cheers, Jin

  • Cannot Access IIS Website Locally Using www

    - by Reafidy
    I have small website hosted on our WS 2008 R2 server using IIS 7. I can access our website from anywhere in the world using: www.ourwebsite.co.nz But from any local computer on our internal network I can only access the website using: http://ourwebsite.co.nz Our employees are constantly asking why they cant just use www.ourwebsite.co.nz I'm not sure what info to provide. I presume that because the wesbite correctly functions from outside the local network that I have correctly setup our Web DNS A records at our domain host. And the problem may lie with our local DNS configuration.
