[Cialug] Remote Access

Mon Aug 14 08:06:51 CDT 2006

I can SSH in to the SuSe box from Win on my local network but not from outside. I 
  have my router set to forward port 23. I cannot figrue out what else it could be. Does anyone have any ideas.

Is sshd (the secure shell server daemon) running on the server you are trying to connect to?

To check you can run the command: 

ps -A | grep sshd

You should get an output similar to this:

myuser at mymachine ~ $ ps -A | grep sshd
 6869 ?        00:00:00 sshd
24780 ?        00:00:00 sshd
24786 ?        00:00:00 sshd
myuser at mymachine ~ $ 

If you do please try to connect to the server using SSH on your server's LAN.

If you can do that then we know it's a problem with the external connection (port forwarding, IP address...)

If you can't then we know it's an installation/configuration problem. 

Thanks,
Gamble

I disable the firewall in my Linux network interface settings, since I have a firewall on my router with port 22 forwarded to my Linux machine.

I think you may be having the same problem as me.  I can't get into my linux box either on any protocol from an off-network pc.  Is there a built in firewall in linux that needs to be setup before attempting to connect?

      I have tried both version 1 & 2. there is a box for Remote command is there a command I should enter here? And On preferred encryption algorithm I have the following options.
  3DES, Blowfish, and DES. There is also a check box for Imitate SSH MAC bug in commercial <= v2.3.x should this be checked.

There are a lot of different settings in PuTTY.  Have you tried various settings?  What protocol version are you using?

  Sorry to keep beating this thread to death but I am still have trouble.

  I have port 19-23 forwarded on my router. I went to dyndns and set up a dns. I can ping the ip remotely (from work) but when I try to do a TELNET session I get a connect failed message. I also have putty installed on my win box at work and when I try ssh or telnet from the win box I get Unable to open connection: connect(); unknown error.

  What type of access do you need? A terminal window, or a full X session, 
or something else? For just a terminal window, i'd recommend 
downloading PuTTY (Google for "putty" and it should be in the first 2 
hits) and using it to SSH to your Linux box. You'll need to make sure 
your Linux box has a routable IP, or forward the SSH port (TCP/22) from 
a routable IP to the Linux box.

X is a bit more complicated; i've never needed to go from MS Windows to 
X Windows. There are projects such as Cygwin that will let you set up 
an X server on Windows and then from there you'd be able to connect to 
the Linux box and run applications. A possibly easier solution would be 
to run VNC on the Linux box and then connect from Windows with a VNC 
viewer. I've done that before, though with Linux or OS X as the client 

  rather than Windows. It gives you a full deskto p, and is much more 

responsive than X over SSH. To use VNC to go from one Linux box to 
another, get SSH working, then on the server do "vncserver :2 -geometry 
1024x768 -depth 8" and on the client "vncviewer -via 
localhost:1". When done you can stop the server with "vncserver 
-kill :1" on the server. I would think that using Windows as the client 
would be similar, though the client command may differ slightly.
