• IPTables masquerading with one NIC

  - by Tuinslak

  Hi, I am running an OpenVPN server with only one NIC. This is my current layout: public.ip > Cisco firewall > lan.ip > OpenVPN server lan.ip = 192.168.22.70 The Cisco firewall forwards the requests to the oVPN server, thus so far everything works and clients are able to connect. However, all clients connected should be able to access 3 networks: lan1: 192.168.200.0 (vpn lan) > tun0 lan2: 192.168.110.0 (office lan) > eth1 (gw 192.168.22.1) lan3: 192.168.22.0 (server lan) > eth1 (broadcast network) So tun0 is mapped to eth1. Iptables output: # iptables-save # Generated by iptables-save v1.4.2 on Wed Feb 16 14:14:20 2011 *filter :INPUT ACCEPT [327:26098] :FORWARD DROP [305:31700] :OUTPUT ACCEPT [291:27378] -A INPUT -i lo -j ACCEPT -A INPUT -i tun0 -j ACCEPT -A INPUT -i ! tun0 -p udp -m udp --dport 67 -j REJECT --reject-with icmp-port-unreachable -A INPUT -i ! tun0 -p udp -m udp --dport 53 -j REJECT --reject-with icmp-port-unreachable -A FORWARD -d 192.168.200.0/24 -i tun0 -j DROP -A FORWARD -s 192.168.200.0/24 -i tun0 -j ACCEPT -A FORWARD -d 192.168.200.0/24 -i eth1 -j ACCEPT COMMIT # Completed on Wed Feb 16 14:14:20 2011 # Generated by iptables-save v1.4.2 on Wed Feb 16 14:14:20 2011 *nat :PREROUTING ACCEPT [302:26000] :POSTROUTING ACCEPT [3:377] :OUTPUT ACCEPT [49:3885] -A POSTROUTING -o eth1 -j MASQUERADE COMMIT # Completed on Wed Feb 16 14:14:20 2011 Yet, clients are unable to ping any ip (including 192.168.200.1, which is the oVPN's IP) When the machine was directly connected to the internet, with 2 NICs, it was quite simply solved with masquerading and adding static routes in the oVPN client's config. However, as masquerading won't accept virtual interfaces (eth0:0, etc) I am unable to get masquerading to work again (and I'm not even sure whether I need virtual interfaces). Thanks.

• JMX Monitoring of GlassFish Servers

  - by tjquinn

  Did you ever wonder what this message in your GlassFish server.log file means? JMXStartupService has started JMXConnector on JMXService URL service:jmx:rmi://192.168.2.102:8686/jndi/rmi://192.168.2.102:8686/jmxrmi It means you can monitor any GlassFish server process, remotely or locally, using any standard Java Management Extensions (JMX) client.  Examples: jconsole or jvisualvm.   Copy the part of the log message that starts with "service:" into the Add JMX Connection dialog of jvisualvm:  or into the New Connection dialog of jconsole: (The full string is truncated in the on-screen display, but if you copied from the server.log and pasted into the form it should all be there.) The examples above are for a DAS, and your host will probably be different.   The server.log files for other GlassFish servers (instances) will have similar log entries giving the JMX connection string to use for those processes.  Look for the host and/or port to be different. Note a few things about security: Here we've assumed you are using the default admin username and password.  If you are not, just enter a valid admin username and password for your installation.  Once connected, you have normal access to all the JVM statistics and controls. You can use JMX clients that support MBeans to view the GlassFish configuration.  When you connect to the DAS, you can also change that configuration, but you can only view configuration when you connect to an instance. To use a JMX client on one system to connect to a GlassFish server running on another system, you need to enable secure admin if you have not already done so: asadmin change-admin-password (respond to the prompts) asadmin enable-secure-admin asadmin restart-domain (as prompted in the output from enable-secure-admin)

• Windows/Samba connection error

  - by Gomibushi

  I have a Linux fileserver serving up /home for linux and windows users. I was able to connect from my windows client, but not from a DC. Then suddenly I could connect from the DC too. The linux servers run Centrify clients, and as such are part of the domain. All on same subnet. This is what the the log.smbd says, repeatedly: [2010/02/11 11:25:57, 0] lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.200.3. Error = Connection reset by peer On Windows it appeared as an "unknown error". EDIT: the error code is "0x80004005". We are developing a system depended on the samba share, and are worried this will appear again. It would be nice to pin point the root of this. Any ideas what this might be? Places to look?

• Why would a terminal server be kicking users off after about 5 minutes?

  - by Matt

  I have a terminal server that was restored from an old 1U server to an IBM HS20 Blade running ESXi. The restore was using shadow protect hardware independent restore. All appeared to be functioning well but we're finding that users are being periodically kicked off after around 5 minutes or so. The interesting thing is it doesn't appear to be a simple disconnect but the whole session has gone like it was logged out. There is nothing significant in the event log, and certainly nothing from terminal services that is logged. I've also checked the client computers and from the client computers logged into our other terminal server and there wasn't any issues there. It doesn't appear to be network related. Any ideas?

• Why is a small fixed vocabulary seen as an advantage to RESTful services?

  - by Matt Esch

  So, a RESTful service has a fixed set of verbs in its vocabulary. A RESTful web service takes these from the HTTP methods. There are some supposed advantages to defining a fixed vocabulary, but I don't really grasp the point. Maybe someone can explain it. Why is a fixed vocabulary as outlined by REST better than dynamically defining a vocabulary for each state? For example, object oriented programming is a popular paradigm. RPC is described to define fixed interfaces, but I don't know why people assume that RPC is limited by these contraints. We could dynamically specify the interface just as a RESTful service dynamically describes its content structure. REST is supposed to be advantageous in that it can grow without extending the vocabulary. RESTful services grow dynamically by adding more resources. What's so wrong about extending a service by dynamically specifying a per-object vocabulary? Why don't we just use the methods that are defined on our objects as the vocabulary and have our services describe to the client what these methods are and whether or not they have side effects? Essentially I get the feeling that the description of a server side resource structure is equivalent to the definition of a vocabulary, but we are then forced to use the limited vocabulary in which to interact with these resources. Does a fixed vocabulary really decouple the concerns of the client from the concerns of the server? I surely have to be concerned with some configuration of the server, this is normally resource location in RESTful services. To complain at the use of a dynamic vocabulary seems unfair because we have to dynamically reason how to understand this configuration in some way anyway. A RESTful service describes the transitions you are able to make by identifying object structure through hypermedia. I just don't understand what makes a fixed vocabulary any better than any self-describing dynamic vocabulary, which could easily work very well in an RPC-like service. Is this just a poor reasoning for the limiting vocabulary of the HTTP protocol?

• windows server 2008 r2 remote desktop issue with roaming clients

  - by Patrick D'Haese

  I have the following situation : a Dell windows server 2008 R2 computer, with remote desktop services installed. I have installed a java application making use of a PostgreSql database, and made this application available for clients using RDP. Clients are standard Win XP pc's and Psion Neo handheld devices running Windows CE 5 Pro. The application works fine for clients on standard XP pc's connected directly via cat 5E Ethernet cable to a Dell Powerconnect 2816 switch. The Psion Neo clients connect wireless to the network via Motorola AP6532 access points. These access points are connected via a POE adapter to the same switch as the XP pc's. The Psion devices can connect without any problem and very quickly to the server and to the application using RDP. So far, so good. When the Psion devices move around in the warehouse, and they roam from one access point to the other, the RDP session on the client freezes for approx 1 minute, and then it automatically resumes the session. This freezing is very annoying for the users. Can anyone help in solving this issue? Update (August 9) : After re-installing the access points we have a working situation, but only when connecting to the RDP host : * via a Win Xp SP3 laptop * via a Symbol MC9190 Win CE 6 mobile device When roaming we notice a small hick-up less then 1 second, what is very acceptable. With the Psion NEO it's still not working, when roaming the screen freezes from 2 to 30 seconds. The RDP client on the win xp sp3 laptop and the symbol mc9190 is version 6.0. The RDP client on the neo is version 5.2. I have changed the security layer on the RDP host to RDP security layer (based on forums on the internet), because older RDP clients seem to have issues with the RDP 7.1 protocol on the Win server 2088 R2. Psion adviced us to do some network logging activity on the different devices. We made this logging via wireshark, and based on this the conclusion of Psion is that the server fails in handling tcp-requests. Can anyone give me a second opinion by analysing the wireshark loggings. Thanks in advance. Regards Patrick

• How to configure chrome to open magnet url's with deluge?

  - by michael_n

  After upgrading to Ubuntu 11.04 (natty) from 10.10, I can no longer open magnet (torrent) links in Chromium, and set deluge to automatically open and accept the url. (Edit: currently ".torrent" files are not a problem, but magnet url's, e.g. of the form "magnet:?xt=urn:...", are now the only problem. Not sure if something updated...?) Rather, now only transmission will automatically open torrents, magnet links, etc. There doesn't seem to be a way to set deluge to be the default torrent client. (And, there also doesn't seem to be a "default application" setting for bittorrent client to replace transmission w/ deluge.) Notes: I found some old threads on this issue, and only a one or two newer ones. The newer threads seem to suggest xdg-open is to blame. But not many people seem to be running into this problem, so... maybe it's just me? Not using firefox, so manually setting apps for mime-types or extensions doesn't work (that's not an option in chrome/chromium, afaik -- you have to rely on the OS) I uninstalled transmission, and then basically nothing happened when clicking on torrent/magnet links. running from the shell also opens transmission (not deluge): xdg-open "magnet:?xt=urn:bt..&tr=http://tracker.....com/announce" My current url handlers are: $ gconftool -a /desktop/gnome/url-handlers/magnet command = deluge "%s" needs_terminal = false enabled = true The only work-around I have (which does work) is to rename /usr/bin/transmission-gtk{,.bak} and create my own /usr/bin/transmission-gtk : $ cat /usr/bin/transmission-gtk #!/bin/bash deluge "$@" Anyone else run into this, know of a bug, workaround, or...?

• DNSHost.exe trojan found, now after fix, no one can print

  - by Matt Dawdy

  What started today as an inability to get to the internet (but people could get in just fine), morphed to we realized that the DNS Server wasn't working, then we figured out that we had a trojan called DNSHost.exe (spybot.rl I think), and we disabled its service entry and deleted the offending file and all registry keys told to use by the Trend Micro site. Now, we can get on the internet, but the printer being served by this machine (called server2) cannot be printed to from any client machine on the network. We get the error "The RPC Server is unavailable". I'm assuming that this is related to the DNS issue we had earlier, as we were able to print just fine until this fun happiness started this morning. Anyone have any solid suggestions? Windows Server 2003 R2 SP2, and the client machine are all Windows XP SP2.

• Messages fail to deliver when sending out a mass email

  - by Jason T.

  A client of mine sent out a mass email to a bunch of people on his contact list. A bounceback email was received by my client stating that: "The server has tried to deliver this message, without success, and has stopped trying. Please try sending this message again. If the problem continues, contact your helpdesk." That error is associated with every recipient in that mass email. Any ideas on where to look to resolve this? He is able to send and recieve other emails normally.

• Why does DataContractJsonSerializer not include generic like JavaScriptSerializer?

  - by Patrick Magee

  So the JavaScriptSerializer was deprecated in favor of the DataContractJsonSerializer. var client = new WebClient(); var json = await client.DownloadStringTaskAsync(url); // http://example.com/api/people/1 // Deprecated, but clean looking and generally fits in nicely with // other code in my app domain that makes use of generics var serializer = new JavaScriptSerializer(); Person p = serializer.Deserialize<Person>(json); // Now have to make use of ugly typeof to get the Type when I // already know the Type at compile type. Why no Generic type T? var serializer = new DataContractJsonSerializer(typeof(Person)); Person p = serializer.ReadObject(json) as Person; The JavaScriptSerializer is nice and allows you to deserialize using a type of T generic in the function name. Understandably, it's been deprecated for good reason, with the DataContractJsonSerializer, you can decorate your Type to be deserialized with various things so it isn't so brittle like the JavaScriptSerializer, for example [DataMember(name = "personName")] public string Name { get; set; } Is there a particular reason why they decided to only allow users to pass in the Type? Type type = typeof(Person); var serializer = new DataContractJsonSerializer(type); Person p = serializer.ReadObject(json) as Person; Why not this? var serializer = new DataContractJsonSerializer(); Person p = serializer.ReadObject<Person>(json); They can still use reflection with the DataContract decorated attributes based on the T that I've specified on the .ReadObject<T>(json)

• Limit maximum incoming connections to a port using iptables

  - by Harley

  I have a server that has apache listening on a number of ports. Some ports are used for configuring the server, and another is used to download large files. My problem is that when I have a large number of clients downloading files, the web interface is uncontactable. I would like to limit the number of clients connecting on the "large file" port so that apache always has available connections to configure the server. A REJECT is fine, the client trying to download the file will back off and retry later. Each client only has one connection open to the server at a time, so limiting by IP won't work. I know I could put something in front of apache to manage this, but I'd really like to do it in iptables, without adding more software.

• MWS2K8R2: Enabling Media Sharing using Streaming Media Services Role

  - by TheLizardKing

  So I have a Microsoft Windows Server 2008 R2 that stores a large collection of media (mostly mp3s) and I want to be able to deliver these files using a server/client setup with Windows Media Player being the client. I downloaded and installed Streaming Media Services Role. I even setup a publishing point with on-demand access. My issue is I can connect using WMP12 but it only connects as more of a stream and not a shared library. I can pause/play/skip as if it's a powerful radio station which is ok in my book but what I'd really like to do is allow me to control my music remotely, search and play for artists, maybe create playlists (not required but nice) and even connect it to an xbox. Is Streaming Media Services Role not what I should be using for this? Would installing WMP and sharing using that mechanism be a better option? Any Ideas?

• Problems serving SVN over HTTPS on Ubuntu 10.04

  - by odd parity

  We've been experiencing some problems with our Subversion server after upgrading to Ubuntu 10.04. When trying to access a repository, regardless of client (I've tried git-svn and svn on Windows as well as svn on Ubuntu 10.04, from different computers and network locations), I get a 400 bad request. Here's the output from svn: svn: Server sent unexpected return value (400 Bad Request) in response to OPTIONS request for 'https://svn.example.org/svn/programs' Here are the relevant entries from the Apache logs (I'm running Apache 2.2): error.log [Mon Jun 14 11:29:31 2010] [error] [client x.x.x.x] request failed: error reading the headers ssl_access.log x.x.x.x - - [14/Jun/2010:11:29:28 +0200] "OPTIONS /svn/programs HTTP/1.1" 401 2643 "-" "SVN/1.6.6 (r40053) neon/0.29.0" x.x.x.x - - [14/Jun/2010:11:29:31 +0200] "ction-set/></D:options>OPTIONS /svn/programs HTTP/1.1" 400 644 "-" "SVN/1.6.6 (r40053) neon/0.29.0" If anyone has run into similar problems or could give me a pointer to track down the cause of this I'd be very grateful - I'd really like to avoid having to downgrade the box again.

• What port does OpenLink ODBC Driver use?

  - by user36737

  I use Avaya Reporting Services and OpenLink ODBC Drivers for db connection. I know that it uses port 5000 for handshaking but after that I believe it uses an random port for communication. I want to deploy my application and it will communicate with the client's system in their datacenter. They are asking what ports should they open on their firewalls. I can't obviously give them a range above 50,000 that I know OpenLink ODBC Drivers use. Can someone tell me what port should I tell my client to open?

• While Mail Forwarding with exim, how do I rewrite the To header with true destination address

  - by Jom

  I have mail forwarding setup with exim using a domain forwarding file. virtual_aliases_nostar: driver = redirect allow_defer allow_fail data = ${if exists{/etc/valiases/$domain}{${lookup{$local_part@$domain}lsearch{/etc/valiases/$domain}}}} file_transport = address_file group = mail pipe_transport = virtual_address_pipe retry_use_local_part domains = lsearch;/etc/localdomains unseen It is working fine. However, I would like to rewrite the "to" header. In my system filter, I would like to put something like: headers remove to headers add "To: $recipient:" I've tried: headers remove to headers add "To: $recipient:" headers remove to headers add "To: $h_env-to:" headers remove to headers add "To: $env-to:" The intent is to have the end recipient see their own email address in the To: line of their mail client. I can't seem to figure out what the correct header is for the final destination of the email so that I can put it in the to header. I've read through the Exim docs and can't seem to find it. I've also looked in the headers in an email at a mail client and can't see it there either. Any suggestions would be appreciated.

• Encrypt LAN and wifi traffic on small private network

  - by Grimlockz

  I need some advice about encrypt all traffic on a small private network running wi-fi and LAN traffic on 192.168.0.x network. The network would comprise of client laptops connecting to the wi-fi router (192.168.0.254) via ethernet connection or wireless. The main purpose of the server is for the client laptops to talk to two servers on different IP's (192.168.0.200 and 192.168.0.201) on ports 80 and 433. My main concern is having packet sniffers and what not getting access to the data. The only ways I see at the moment is to have VPN running on the network or use IPSec policy's to do this. Any other ways guys?

• How Do I Restrict Repository Access via WebSVN?

  - by kaybenleroll

  I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

• Why use Google Apps Sync for Outlook to sync email?

  - by Howiecamp

  I currently use Outlook 2007 against an Exchange server for my email and will be moving to Google Apps. There are a number of ways to import your existing email and calendar entries into Google Apps Gmail (e.g. including the Google Apps Sync for Outlook tool), the Google Email Uploader, and copying messages using an IMAP client) so I'm covered on the import side. I'm trying to understand the use cases for the Google Apps Sync for Outlook tool http://mail.google.com/support/bin/topic.py?topic=23333 with respect to email and calendar entries. The description says it syncs your Outlook email and calendar items with Google Apps, but doesn't using Outlook as an IMAP client against Google Apps do the same?

• Maximizing TCP connections on HAProxy load balancer

  - by imaginative

  I am currently using HAProxy in order to load balance tcp connections from clients to my Erlang app server. The connection is persistent, which means I'm limited to roughly 64K clients on an optimized server (I'm currently running HAProxy on an m1.large EC2 instance). My app server is designed to horizontally scale based on the number of TCP connections. What's worrying me though is I'll need an equal number of HAProxy servers as app servers since it's a 1:1 connection. Is there currently a way to "proxy" the tcp connection to the app server so that once HAProxy sends the client off to my Erlang server, it can free up the connection, ready to serve another client? Are there any papers, existing solutions out there I can read so that I only have to worry about the 64K limit on my app servers, and not on the load balancing servers themselves?

• Can I host a website on a different address from the webmail?

  - by Andrew

  I have what is to me an unusual situation. I have a client for whom I have built a website which I will be hosting, they have been using their domain name for their email addresses for a long period before I came along so moving their email account to my host would be problematic and building the website with their current host would also be problematic because their host is very restrictive. So to fix this I altered the A record in their existing control panel to point the domain name to my server. As a result I can see the pages that I have created at their domain and they can still access their existing webmail. However, it appears that they are now experiencing problems receiving email so I can only assume my solution was incorrect. What is the correct way to point their domain at my website but keep their webmail with the existing host? EDIT: 25/5/2012 - My client has finally responded to me after changing the MX record on their existing C-Panel. Email to their email address were being bounced back with the error 'no such recipient', so I set up the same email address in the new C-Panel and changed the MX record there to 'Remote mail exchanger' which has stopped the emails bouncing but has apparently lost them in cyperspace! Unfortunately I can't add a new record because this would require a fully qualified domain name and their domain name is of course pointed at our server!

• Search inside Xournal files (.xoj)

  - by Javad Sadeqzadeh

  I'm a big fan of Evernote, I use it regularly. However, it has a 60MB storage limit (although text files are not going to occupy much space, but the limitation concern still remains). Today, I installed Xournal, which has great features like annotating, nice background, free hand shapes and notes, save in PDF format, and many more. But the big problem is that as far as I've noticd, there is no intrinsic feature for seach inside the notes (created using Xournal with .xoj suffix). I used Catfish File Search application (which creates bash commands for full text search), but it couldn't help as well. Is there anyway to search inside a .xoj file at all? If so, it could be a suitable alternative to evernote, if you put your .xoj files on a cloud (which certainly offers you much more storage space than 60MB). If not, is there any other convenient app similar to Evernote, but with higher storage limit or without a limit? Somebody suggested Zim desktop wiki app, which looks great, but I'm nut sure if I could copy and paste everything there (a mixture of photos and tables and text with various formats and highlights), like what I do with Evernote. And a very useful tool I use is Evernote Web Clipper (browser extension). Of course, having a desktop client like Everpad is a plus, but not the absolute need. PS: I use pocket, so please do suggest that (it only preserve links (which might change over time) not the actual text). I also use google drive or docs, I don't like that for this purpose niether, it's too slow, doesn't have a browser extension and a desktop client. Thank you so much in advance.

• Management VLAN Cisco Catalyst

  - by cha789

  I have configured a couple of VLANs on a Cisco Catalyst switch, i will put all the ports that clients is connected to, into these VLANs. I want to configure the native VLAN [vlan 1] as management VLAN so i can use a telnet client to connect to the switch. How can i block all but one specific IP-address to telnet into the switch? As i understand vlan 1 has many task regarding different protocols and i do not want to break that but only allow one specific IP-address to connect to the switch with a telnet client [actually the gateway ip address of the switch].
