KSH, coprocess and SSH
Hi there,
I want to connect to a Cisco router with a KSH script via coprocess:
telnet 192.168.2.82|&
print -p “login”
print -p "password"
With telnet it works. Now I want to use SSH:
ssh -T -l login 192.168.2.82|&
print -p "password"
The router answer me I enter a bad password, "Permission denied, please try again.". I begin to find some informations about this problem, that SSH haven't got the good stdin but I did not understand.
Thanks
Sylvain

This is probably a simple one for the wise.
I have just started using a coprocess (first time) in order to facilitate telnet'ing from inside a shell script. It's working, but when I run a remote command I need to get the output into a local variable, but alas my kung-fu is weak.

fence_rsb
FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)
NAME
fence_rsb - I/O Fencing agent for Fujitsu-Siemens RSB
DESCRIPTION
fence_rsb is an I/O Fencing agent which can be used with the Fujitsu-Siemens RSB management interface. It logs into device via telnet/ssh
and reboots a specified outlet. Lengthy telnet/ssh connections should be avoided while a GFS cluster is running because the connection will
block any necessary fencing actions.
fence_rsb accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent.
fence_rsb can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
