ssh top

Tonatiuh — Tue, 12 Aug 2008 21:24:47 GMT

$ ssh remote_host top
top: Unknown terminal "VT100" in $TERM

The remote host is Red Hat Enterprise Linux 3 and has the environment variable XTERM=vt100.

The local host is Red Hat Enterprise Linux 4 and has the environment variable XTERM=xterm.

Any idea?
Should I change set XTERM=xterm into the remote host? what other funcionaliti is going to change or fail if I change that variable in remote host?

I think that is complainig about VT100 upper case, change to lower case vt100.

Shalom

export TERM=vt100

Might want that in the user profile as well.

Ivan:

The upper case is only the message shown, the value of the env variable is "vt100".

Steven:
I have set the env variable XTERM=vt100 in the local machine but the result is exactly the same error message.

Even if you get the TERM assignment to work, the command will probably still fail.

I've got a test below going from RH5 to RH4 (not the same, I know, but as close as I could come)...

$> ssh remote_host "(export TERM=xterm; top)"
top: failed tty get

I tried with "ssh -X" and got the same thing.

The problem is, it will fail the "isatty()" code check in the program.

So, what you need is a whole new xterm:

$> ssh -X remote_host "xterm -e top"

Now you'll get a new window with top running in it.

Close enough???

ssh -X remote_host "xterm -e top" works well for me.

Thank you!
