create these scripts and make them executable. it should give you a good starting point. add error logic as needed

server1.ksh
Code:
#!/usr/bin/ksh

USER2=foo
SERVER2=bar

uptime=$(/usr/bin/ssh $USER2@$SERVER2 /path/to/server2.ksh)
# check $? for ssh errors

echo "uptime: $uptime"

server2.ksh
Code:
#!/usr/bin/ksh

nodeName=blah
/opt/OV/bin/snmpget -r 0 -t 60 $nodeName system.3.0 | cut -d: -f3-5


then run it
Code:
ssh $SERVER1 /path/to/server1.ksh

In my earlier post when i said that i wanted to get it working, i meant, i wanted to know how to get the meta-character thingy working..

Yeah, and this(using 2 scripts) is the other way i implemented my script, and works like a charm, thanks for your help frank..

Wish you a Merry Christmas and a happy new year,

try this.

Code:
/usr/bin/ssh -t $USER@$SERVER1 "/usr/bin/ssh $USER2@$SERVER2 'echo -n uptime;/opt/OV/bin/snmpget -r 0 -t 60 $nodeName system.3.0 | cut -d: -f3-5'"

it has to do with the quoting and command substitution. using back ticks `` without single quotes was actually causing snmpget to be run on the current system. I simulated the same behavior with echo -n so you don't have to worry about that and also added quotes. it can get tricky and unmaintainable doing things like this.

Hey Frank,
I have a smilar problem, where my ssh is not working when I am trying to do the su - user.
Code:
ssh -t -f 172.18.197.41 "su - d_od 'ls -lrt /usr/dev/ods|head -10'"

It is working fine if I am not doing the su:

Can you pls helpme with this.
