[mpls-linux-general] help: how to ssh to mpls machine?

[mu w <mu...@gm...>]

 (ssh to non-mpls machines via mpls net works) -- one more time

OK the previous email didn't get through...please forgive me for reposting.

Hi James and all...

I built an mpls network using static label switched path, by  using mpls 
nhlfe...and mpls ilm...etc (in 2.6.9-1.6_FC2mpls_1_946). Everything 
works fine except I cannot ssh to an mpls machine.
The following figure show my network
                       
    ulm1--ulm2---ulm3----ulm4 
    
ulm2 and ulm3 are the mpls network, ulm1 and ulm4 are normal IP hosts. 
ulm1 can ssh to ulm4 (traffic on ulm2 and ulm3 are labeled) but cannot 
ssh to ulm3. ping to ulm3 is okay.

Ethereal shows the mpls traffic for ssh handshake...SYN and stuff but 
the connection was reset after a while.

Is ssh to ulm3 possible? If yes how to setup?

I have seen question on ftp and ssh questions in the archive but can't 
find any answers. Any help and pointer are appreciated.

Also, is there a more detailed manual for the mpls command in (uname -a 
= 2.6.9-1.6_FC2mpls_1_946)?
