[SOLVED] Routing problems with ssh server and openvpn client

My current setup is an arch box behind my wireless router. My wireless router is running scripts to update the dynamic dns for my internet connection and forwarding incoming requests to port 22 on the arch box. Simple so far.
Now I'd like to setup OpenVPN on the arch box to connect to a 3rd party vpn service but still listen for ssh connections. This way I can have my arch box always connected to the vpn but be able to access it from anywhere. I believe the problem is that openvpn sets up a default route to send all outgoing traffic out over the tunnel, but I don't know enough about routing to make this work. I saw another solution in the forum was running virtualbox and I find that so inelegant. I'm planning on eventually learning more about ip route and iptables but I was also hoping that a networking guru could help me get this set up quickly in the meantime.
ip route while not connected to vpn
default via 192.168.1.1 dev eth0 metric 202
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.11 metric 202
ip route while connected to vpn
0.0.0.0/1 via 10.120.62.9 dev tun0
default via 192.168.1.1 dev eth0 metric 202
10.120.62.1 via 10.120.62.9 dev tun0
10.120.62.9 dev tun0 proto kernel scope link src 10.120.62.10
23.29.126.102 via 192.168.1.1 dev eth0
128.0.0.0/1 via 10.120.62.9 dev tun0
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.11 metric 202

First, meop, thanks for your reply. I did not use that method to solve the issue, but I'm going to do some more research into it (I'll speak to why I went another direction after the solution).
My solution so far has come from this resource http://forum.linode.com/viewtopic.php?t=8737
Since my server is behind a router, I do not have to worry about the public IP address changing and I was able to use the private IP in the route statements. Therefore, in my case, the solution was these three lines:
ip rule add from 192.168.1.11 table 128
ip route add table 128 to 192.168.1.0/24 dev eth0
ip route add table 128 default via 192.168.1.1
Keep in mind, as the article states, that applies to all ports (not just ssh). If you want to block other traffic, you need some extra iptables entries.
This also solves my end goal: Being able to connect to this 3rd party VPN with a simple ssh redirect from my always connected server. I can now ssh -D <port> <myhost>, set up chrome to use <port> as a proxy, and have everything redirecting over this VPN connection without any hassle.
meop, this setup is connecting to a 3rd party VPN service and they provided the config scripts for the client. I considered tinkering with that, but found this solution to work and I'm going to do some more reading about each solution to figure out which is the best overall.
enovak, I grepped dmesg and did not see any entries about martian source.
Now another question that comes to mind: What if this server were actually NOT behind a firewall and it's public IP changed? I think you'd somehow have to have a script to check to see if your Dynamic IP address changed and also have a route that only that script would use (send everything else out the VPN route). Then, if your IP address changed, you'd have to change these routes around. I'll leave that solution to someone else :-)

Strange problem with AIX server and windows clients

I am having a real bizzare problem with WLS 7.0.1 running on AIX 5.1 and
clients on windows. We have J2SE Swing application as a client.
If the client is w2k or XP, the first client gets good response. If I start
another client the second client is horribly slow (2 sec vs 16 sec). Even if
I kill the first client the second client continues to be slow. If I have 2
clients open together, the first one continues giving 2 sec response while
the second one continues with 16 sec. For that matter if I start another
client after shutting down first one I get slow (16 sec) response.
If the client is NT client I always get good and consistent response from
the server. Irrespective of how many client I have on the NT machine, I keep
getting good response. NT and W2K laptops are seating right next to each
other on the same n/w and infact the NT is a much slower and lessor memory
machine than W2K.
We did similar tests keeping server on Solaris or NT server or W2K server,
and the clients "behave" normally i.e I get consistent repsponse time (it
may be slow or fast, but it is consistent and is consistent b/w NT and W2K).
We even tried putting my laptop on the same network as the AIX server, but
it did not help. Unfortunately some of our clients will be using AIX and
W2K.
HELP!!!!

Sounds like a reverse DNS lookup or similar network timeout.Thanks for the suggestion, but then why would the first client on w2k or XP
get a better performance and the subsequent clients get worse performance?

Problems with games server and client

Hi! I am making an MMORPG game and I have problems with the server and client connection.
I can connect to the server, but when a second player does, the server console tells me this:
java.net.SocketException: Connection reset
After that, all clients disconnect.
Which is the problem?
How can I solve it?
Thank you so much

Here is how my sever work. I took some of this code from a book called Killer Programming Games in Java. If you google for it, you will find it for sure.
TourGroup tg = new TourGroup(); // this object stores information about all clients connected to the server
    try {
      ServerSocket serverSock = new ServerSocket(PORT);
      Socket clientSock;
      while (true) {
        System.out.println("Waiting for a client...");
        clientSock = serverSock.accept();
        new TourServerHandler(clientSock, tg).start(); // this is the thread that monitors each client
    catch(Exception e)
    { System.out.println(e); }
} This is some code of TourServerHandler
public TourServerHandler(Socket s, TourGroup tg)
    this.tg = tg;
    clientSock = s;
    name= "?";
    cliAddr = clientSock.getInetAddress().getHostAddress();
    port = clientSock.getPort();
    System.out.println("Client connection from (" +
                 cliAddr + ", " + port + ")");
public void run()
// process messages from the client
    try {
      // Get I/O streams from the socket
      BufferedReader in = new BufferedReader(
   new InputStreamReader( clientSock.getInputStream() ) );
      PrintWriter out =
new PrintWriter( clientSock.getOutputStream(), true );
// and here goes the rest... The TourServerHandler thread uses this code to send messages:
tg.broadcast(msg); tg.broadcast works like this:
synchronized public void broadcast(String cliAddr, int port, String msg)
// broadcast to everyone but original msg sender
    TouristInfo c; // this object stores info about the client
    for(int i=0; i < tourPeople.size(); i++) {
      c = (TouristInfo) tourPeople.get(i);
        c.sendMessage(msg);
} This is the error part
public void sendMessage(String msg)
PrintWriter out;
    out.println(msg);
      System.out.println("OK");
} I can't find any error but I still get that Connection reset exception...

[SOLVED] a problem with gpg-agent and ssh keys

I'm baffled by a strangle problem:
My setup is as follows: I use gpg-agent with --enable-ssh-support, so that my ssh keys are handled by it. All was fine (when I ssh'ed to another machine, a pinentry window popped up, asked for a password, and if I entered the correct one, gpg-agent would decrypt its copy of my private ssh key and use it for identification). But: I needed to change my ssh key, and so I generated a new one. Next, I ssh-add'ed it to gpg-agent (one password to decrypt the private key, then twice another password for gpg-agent). I uploaded the public key to a server. The setup should be complete.
The problem is that when I ssh to a machine, a pinentry window comes up, but it does not accept my password (the one that I entered twice when ssh-add'ing the key). I tried adding with various different passwords (always deleting ~/.gnupg/private-keys-v1.d/*, since 'ssh-add -d ~/.ssh/id_rsa.pub' would not work for some reason - it would not make gpg-agent forget the key), different pinentry programs ( -qt4, -gtk-2, -curses), and still the same problems. Pinentry itself seems to work fine, since if I enter two different things when it asks for a new passphrase for the key, it detects that there's a problem.
So, can anyone help? What could I try (please don't post just to say that I could/should use ssh-agent, or keychain, or anything else. I have used various things, and I like this setup the most. It worked before, and I would like to find out why it stopped working and how to get it back to speed.)
Thanks.

Thats a known bug with the new gpg version.

You could use an older version of gpg or use a development version.

Problems with mail server and clients

I have set up OS X server on my iMac with 2 MacBook Pros as clients. I have set up the server to be a mail server.
I have two problems.
1. I can successfully send and receive emails between the server and one MacBook Pro but neither send or receive mail on the other even though the settings are identical. I get the standard dialog box 'cannot connect using Port 25'.
2. On the MacBook Pro that will send mail I can also send mail out of the LAN but mail sent to me is bounced back to the sender.
Any help would be greatly appreciated. I am new to OS server my learning curve over the past week has been vertical!!!

You are not alone. I have started a current thread because of the same problem, http://discussions.apple.com/thread.jspa?threadID=1278072&tstart=0.
Another thread ended with the poster claiming to have things working after a clean install, but I have had no such luck with any of my installations so far.
Do you have only one domain on your server, or are you hosting virtual domains also?

WRT54GC Wireless router problem with iPod touch and Ipad

Hi
I have a WRT54GC wireless router and both my ipod touch and ipad can connect to the network. They can both use the internet for like one minute and then the internet becomes very slow, and dies. Network connections are lost and I'm getting messages like 'can't connect to itunes' or 'lost connection with youtube'. The wireless router works fine for the laptops in the house (all windows). In the house where I live in the week (closer to my school) there is another router and i don't have the problem over there, also no problem to connect to my schools wireless network... So I think it's a combination problem of apple products and that router. I've tried a lot, like resetting network configuration, updating firmware, changing from wpa to wep1,... Anyone an idea?
Thank you
Bert

oh and the connection to the router isn't lost.
Thank you

I am trying to set up my outlook 2007 account on i pad and the process sticks on verifying. It would appear to be a problem with outgoing server and I have changed the port number but with no success.

I have just purchased an i pad 2 and am having trouble with the e-mail set up. Set up with wi-fi, i-cloud etc has worked fine but the i pad is recognising my outlook 2007 account details but is not verifying it. The trouble appears to be with the outgoing server and I have tried changing the port number, but to no avail! Also reset the account settings for holding messages on the server...help! As you can tell I'm not very techy and I'm desperate to get the bloody thing working as I'm going away on Tuesday! Any suggestions?

I had a similar issue and it was password case sensitive issue

Problem with Reports Server and invalid DB packages when release code

Hello,
I'm not certain that this is a Reports issue or not, but wondered if anyone had encountered similar. We've recently upgraded from Forms and Reports 6i to 10.1.2.0.2. A couple of times now, after doing a release of code to our environment, we find that the next request to the Reports Server generates a 'existing state of packages has been discarded' error. Submitting exactly the same report request a second and subsequent times works fine.
However, we always make sure we recompile all invalid packages after a code release; and our Forms front-end doesn't encounter any errors like this. Is there some possible issue with using existing Reports engines to run reports after a code release - should we be bouncing the Reports server..?
Thanks,
James

Hi. Thanks for your quick response. The contain of StrSql is:

I tryied the same sql setence with SQL Server Management Studio Express and it works fine. Already I have tryied with others sql sentences. All they worked fine in SQL Server Management Studio, but not with my java example using sqljdbc4.jar.
sqljdbc4.jar documentation comment that these driver work with sql server 2000 to sql server 2008. I'll ask this cuestion in Microsoft forums.
Thanks.

Problem with previews browser and email clients vs DW

Hey everyone. I am having an issue with DW. I wanted to see if I could get some quick help. I am having a problem with the DW Design looking fine and great on my screen in DW, but when I go to preview in a browser or upload to an Email client, it has a spacing issues. See pics for reference. The first is in DW, the 2nd is in Chrome. All browsers and MailChimp.com look the same.
Can I get some help into what I am doing wrong?

I take it you are using an older version of DW - say DW5? First thing to know is that DW's Design view is not a browser. It's an approximation (and sometimes a poor one) of what you will see in the browser, as you are discovering. Second thing is that by just looking at a screen shot, we can only guess at what might be wrong. Please show us the code and we can tell you what actually IS wrong. Do this by either posting a link to the uploaded page, or by pasting the code into a reply here. If CSS is involved, please add that to your paste. And to be successful with this latter method, you must come to the web forum to make your post - email won't work.

Problems with ical server and mail

I have a Mac Mini with Mac Os X Snow Leopard Server. I have a external mail and when I receive a invitation ever it adds to local calendar, but I want to add in server calendar. How to configure it for add invitation to my server calendar?
Another problem I have with calendar that's I can't send invitation to contacts I have added in CardDav Server, just I can send invitations to local contacts.
And another question how to sync the user's contacts with CardDav account?
Message was edited by: jvcapo

this is a big pain in the ***, bug!
when you have more than one calendar account (lets say one local one CalDAV iCal starts doing silly things.
what i found that worked is click on the calendar you want the event to be in and drag the .ics to iCal from Mail and drop it on the calendar (in the middle of iCal NOT the Calendars name)
i have write up a bug report to apple so hopefully it gets fixed now that MobileMe uses CalDAV.
seems to be a problem that mail app doesn't see CalDAV calendars.

[SOLVED] [lxc] Problems with archlinux template (and systemd)

Hello, recently I was pointed to lxc. I tried the archlinux and debian templates (ubuntu and fedora doesn't work because the "arch" command cannot be found but curently I don't care about these templates).
The debian template seems to work just fine but the archlinux template doesn't.
I think the main problem is that the arch-system runs with systemd while debian still uses initscripts. I found some resources saying that systemd does not work within a lxc-container while others say that some modifications have to be done in order to make systemd to work properly. But all modifications (I found) that should be made are already included in the archlinux template. But it is still not working for me. :-(
The output is as follows:
# sudo lxc-start -n test-arch
systemd 203 running in system mode. (+PAM -LIBWRAP -AUDIT -SELINUX -IMA -SYSVINIT +LIBCRYPTSETUP +GCRYPT +ACL +XZ)

I created the container with
sudo lxc-create -t archlinux -n test-arch
and did nothing more because it seems to me that nothing more should be needed.
I read a lot and most readings say that one has to use initscripts because systemd is not working while others say systemd is working with modifications, e.g. https://wiki.archlinux.org/index.php/Lxc-systemd
But above is everything I get, no login-prompt or anything else, it just hangs. Trying to invoke "lxc-stop -n test-arch" initiates the shutdown but then both terminals just hang and I have to kill the lxc-start process.
I would like to know:
1. is it possible to run a container with systemd? Or do I have to use initscripts?
2. are there any modifications I have to do besides the modifications already provided by the archlinux template script (in order to use systemd)?
3. what possibilities do I have to see what's missing or configured wrong?
Thank you very much. ;-)
// Edit:
Ok, sorry for the noise.
As a last chance I tried a fresh Arch installation within a VM and that works fine (I should have tried this first :-( ). It turned out that my problem is that I am running the ck-kernel which lacks support for "Cgroup sched" and "Cgroup cpu account".
I will ask the ck-guy to support these options.
Until then I will have to use the kernel from the core-repo.

Yes, that was it. Sometimes I don't see what is right in front of me. The devices work as expected, thank you Strike0.
I have one question left. Now wifi and ethernet connection are established during boot (whenever possible). Is there a way to establish connections on demand? Is it possible to trigger the netcfg profile "ethernet-dhcp" when the cable is plugged in or "wireless-wpa" when in range?

I am getting sync problems with Exchange Server and local outlook. Error code is 18439. Does anybody have an idea what the problem might be?

Problem with Airport Express and Ethernet Clients

Hello All, I'm stumped so I hope you can help me out!
I've got a aiport express wirelessly extending an aebs which is creating a network from my isp's router. Everything's working fine. I'm trying to add a Sonos Play5 to the airport express via the ethernet port ( I can't get the Play5 to connect wirelessly). Problems is when I plug the Sonos into the ethernet port the Sonos works fine, but everything else on the network gets booted off. I can't recconnect any of my macs or i-devices. When I uplug the ethernet cable from the Sonos everything reconnects and works as it did before.
I've got the airport express set to "Extend a wireless network" in the aiport utility.
Any ideas as to what I'm doing wrong?

So my connectivity issues are only when I connect the Play 5 to the AX ethernet port.
That would be the Ethernet port on the AirPort Express then, correct?
If yes, I don't understand why other devices would work when connected to the AX and the Sonos 5 does not. All that I can think of is that the Sonos 5 might require more bandwidth than the wireless "hop" between the AEBS and AX can provide.
In effect, the Sonos is really connecting using wireless. You are just changing the wireless to an Ethernet connection at the AX to connect to the Sonos product.
If that is the case, then you are going to have to pull an Ethernet cable so that the Sonos 5 connects directly to the AEBS. You can run Ethernet 300+ feet or 100 meters with virtually no loss.
I would recommend that you check with Sonos Support to report your findings during your "tests" and ask them if there is some reason why the connection won't work over wireless.
Please report on your findings.

Problem with ssh and bash-completion

I and a co-worker are having a weird problem with ssh and bash-completion. We have a local config in .ssh/config with hosts we connect everyday. An example:
host foo
hostname foo.org
user foobar
host foobar
hostname foobar.org
user foobar
When we try to type
ssh foo<tab><tab>b<tab>
the console just freeze and we can't type anything, everything we type is ignored, but after about 30 seconds the host is completed.
This works a some time ago, so some upgrade make this happen. Anyone can reproduce this?
