It wouldn't even work locally. Go ahead and try it, see what happens. su will run, and cd will not run inside it - but it will run, after su quits, because that's what semicolon means. Run this command, wait for it to quit, then run that other command.
To feed something into a program, you need to use redirection.
What I do to run scripts remotely is something like:
The final EOF can't be indented, at all.
When in doubt, replace 'ssh' with 'cat' to see exactly what script you're trying to send to the far side!
I have a linux box build11 which can be pinged from build18 (Windows) box. And we can only login to the box (using SSH) from build18 box. Plz help to characterize the problem, network, DNS, DHCP, etc (or whatever which I am unsure)
Any idea what may be the reason ? :confused:

Hi,
I am writing a script on Solaris 10 and want to execute a remote ssh command. Normally this command should just return the value 0000000000002356 but when using ssh it seems it is passing the result to the shell to execute.
ssh root@10.5.112.145 `/usr/bin/nawk -F\, '$1=="USG" && $2=="01"... (3 Replies)
I have a Solaris 9 server that does not return a ping. When I try to log in via SSH I eventually get in. I am logged in now.
I know this is a wide open question, but can you recommend some things I should check?

dbd::gofer::transport::stream
DBD::Gofer::Transport::stream(3) User Contributed Perl Documentation DBD::Gofer::Transport::stream(3)NAME
DBD::Gofer::Transport::stream - DBD::Gofer transport for stdio streaming
SYNOPSIS
DBI->connect('dbi:Gofer:transport=stream;url=ssh:username@host.example.com;dsn=dbi:...',...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY='dbi:Gofer:transport=stream;url=ssh:username@host.example.com'
DESCRIPTION
Without the "url=" parameter it launches a subprocess as
perl -MDBI::Gofer::Transport::stream -e run_stdio_hex
and feeds requests into it and reads responses from it. But that's not very useful.
With a "url=ssh:username@host.example.com" parameter it uses ssh to launch the subprocess on a remote system. That's much more useful!
It gives you secure remote access to DBI databases on any system you can login to. Using ssh also gives you optional compression and many
other features (see the ssh manual for how to configure that and many other options via ~/.ssh/config file).
The actual command invoked is something like:
ssh -xq ssh:username@host.example.com bash -c $setup $run
where $run is the command shown above, and $command is
. .bash_profile 2>/dev/null || . .bash_login 2>/dev/null || . .profile 2>/dev/null; exec "$@"
which is trying (in a limited and fairly unportable way) to setup the environment (PATH, PERL5LIB etc) as it would be if you had logged in
to that system.
The ""perl"" used in the command will default to the value of $^X when not using ssh. On most systems that's the full path to the perl
that's currently executing.
PERSISTENCE
Currently gofer stream connections persist (remain connected) after all database handles have been disconnected. This makes later
connections in the same process very fast.
Currently up to 5 different gofer stream connections (based on url) can persist. If more than 5 are in the cache when a new connection is
made then the cache is cleared before adding the new connection. Simple but effective.
TO DO
Document go_perl attribute
Automatically reconnect (within reason) if there's a transport error.
Decide on default for persistent connection - on or off? limits? ttl?
