Executing a Telnet command in an ssh command

Question

I want have a Telnet command inside the ssh command for executing the Telnet command at the remote machine (172.202.230.22). I tried with the command

ssh Administrator@172.202.230.22 telnet 10.86.114.10 8088

It is giving an error message like

command not found (error code:127),

But when I tried to execute the same Telnet command directly at 172.202.230.22 it is executing fine. What is the reason?

It looks like you are Cygwin. Are you trying to invoke the windows version of telnet or the cygwin version (I assume there must be one). — Rilindo, Sep 06 '11 at 03:02

Specify the full path to telnet:

$ ssh Administrator@172.202.230.22 /usr/bin/telnet 10.86.114.10 8088

also try nesting the command in single or double quotes, as I think ssh parses the arguments in a space separated list. – mbrownnyc Sep 02 '11 at 19:34
Putting the command into quotes is unnecessary. – MikeyB Sep 02 '11 at 19:53

Because of you are connecting as Administrator user, so I think 172.202.230.22 is a Windows server.

Make sure that you have C:\WINDOWS\system32 in your PATH:

$ ssh Administrator@172.202.230.22 path
PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem

If not, try to use the full path to the telnet.exe:

$ ssh Administrator@172.202.230.22 '"C:\WINDOWS\system32\telnet.exe" 10.86.114.10 8088'
