Commands not working with ssh remote login

Shell Programming and Scripting
1

Hi Friends,

I am unable to run our application commands on remote server using ssh (passwordless login enabled). But the same command running with telent perl script. please suggest.

SSH:

C:/bin>ssh -l monitor tl04cp01 exec "/home/monitor/123"
/home/monitor/123[2]: viewlog:  not found.

Telnet: (perl)

C:/bin>cat test.pl  <---- (perl script to login with telnet)
#! /usr/bin/perl -w
use Net::Telnet ();
$hostname = "$ARGV[0]";
$username = "$ARGV[1]";
$password = "$ARGV[2]";
$t = new Net::Telnet ( Timeout=>20, Errmode=>'die');
$t->open("$hostname");
$t->login("$username","$password");
@alarm = $t->cmd("/home/monitor/123");
print @alarm;

Successfully executed:

C:/bin>./test.pl 10.110.200.1 user121 'xxxxxx'

Unable to decipher and understand the logics, I still guess that you are using different users (monitor/user121) and hosts (tl04cp01/10.110.20.1).

Yes. users may differ. but, the script which my application is using is not executing with ssh and same is working with telent login

4

Are you aware that the environment may be seriously different for two users? That might be the reason for the logged error.

Hi,

I tried with same user, still getting same error. Do we need to enable any thing extra for ssh login?

For both logins, post the environment and the path to viewlog .

Thank you so much , it is working now.

How about posting your findings on what went wrong for the benefit of others in a similar situation?
