Xmanager Forum

Hi,

I have a problem with the configuration of xmanager under Windows XP. My computer is connected to internet via an ADSL-router (Thomson Speedtouch 510).

I cannot connect to a UNIX machine by using the REXEC protocol.
In the NAPT option of the router, I have forwarded the tcp port 6001 of my router to the port 6000 of my computer. In xstart, I use the command line
/usr/bin/X11/xterm -ls -display 10.0.0.39:1
where 10.0.0.39 is the local address of my computer. Each time I try to connect I get the error message:

Cannot connect to the remote host. Please make sure if the host is ready.

I can connect to the UNIX machine with a telnet program (not xmanager). I cannot use the SSH protocol as it is not accepted by the UNIX machine.

Can you help me ?

Thanks,

Mike

Please select the TELNET protocol in Xstart. It seems that your Unix server doesn't support REXEC protocol.

And you should set DISPLAY as router's ip address and port in the command line.

/usr/bin/X11/xterm -ls -display ROUTER_IP_ADDR:1

Hi,

I know the Unix system accept the rexec protocol because I used it before when I was connecting via a 56K modem.

What IP address do I have to use with "-display" in the command line with the rexec protocol ?
The IP address of my router is dynamic, and change at each connection. How can I determine that address ?

Thanks for the help,

Mike

If your router gets a dynamic IP address, you can use REMOTEHOST variable like this:

  /usr/bin/X11/xterm -ls -display $REMOTEHOST:1

The REMOTEHOST environment option is available in Linux servers. If your Unix doesn't support it, you can add the following lines to your login script:

  REMOTEHOST=`who am i | sed -n 's/.*(\([^) ]*\).*/\1/p; 1q'`
  export REMOTEHOST

For csh-like shells, do the following:

  setenv REMOTEHOST `who am i | sed -n 's/.*(\([^) ]*\).*/\1/p; 1q'`

In addition, select TELNET protocol in Xstart.

Hope to solve the problem.
