Display Running Commands on a Remote Linux Server over SSH
Hello,
I'm trying to create a ksh script to ssh to a remote server, enter the password and a couple commands. For security reasons I have changed the login, password and ip in my example.

Code:
#!/bin/ksh

ssh -t -t username@12.5.5.3 << EOF
password
cd bin
pwd
EOF

When I run it. It stalls at the password prompt and it will only continue when I manually enter it. I see the errors are produced due it entering the info too quickly. Is there a way for it to accept the password via script and then wait a certain amount of time before executing the commands? Also need it to exit the remote server when it completes. Any help is much appreciated, thanks.


Example results:
Code:
# /home/test/testscript.ksh
username@12.5.5.3's password:      <----STALLS HERE. ONLY PROCEEDS WHEN I ENTER THE PASSWORD MANUALLY.
password
cd bin
pwd
[username@remoteserver ~]$ password
[1] 27729
-bash: pas: command not found
-bash: sword: command not found
[1]+  Exit 127                pas
[username@remoteserver ~]$ cd bin
[username@remoteserver bin]$ pwd
/home/user/bin
[username@remoteserver bin]$       <----STOPS AND STILL ON REMOTE SERVER.

knife-ssh

KNIFE-SSH(1)							    Chef Manual 						      KNIFE-SSH(1)

NAME

       knife-ssh - Run a command or interactive session on multiple remote hosts

SYNOPSIS

       knife ssh QUERY COMMAND (options)

       -a, --attribute ATTR
	      The attribute to use for opening the connection - default is fqdn

       -C, --concurrency NUM
	      The number of concurrent connections

       -m, --manual-list
	      QUERY is a space separated list of servers

       -P, --ssh-password PASSWORD
	      The ssh password

       -x, --ssh-user USERNAME
	      The ssh username

       -i, --identity-file IDENTITY_FILE
	      The SSH identity file used for authentication

       -p, --ssh-port PORT
	      The ssh port

       --[no-]host-key-verify
	      Verify host key, enabled by default.

DESCRIPTION

       The  ssh  sub-command  opens  an  ssh  session  to each of the nodes in the search results of the QUERY. This sub-command requires that the
       net-ssh-multi and highline Ruby libraries are installed. On Debian systems, these are the libnet-ssh-multi-ruby and libhighline-ruby  pack-
       ages. They can also be installed as RubyGems (net-ssh-multi and highline, respectively).

TERMINAL MULTIPLEXING AND TERMINAL TAB SUPPORT

       knife  ssh integrates with several terminal multiplexer programs to provide a more convenient means of managing multiple ssh sessions. When
       the COMMAND option matches one of these, knife ssh will create multiple interactive ssh sessions running locally  in  the  terminal  multi-
       plexer instead of invoking the command on the remote host.

       The available multiplexers are:

       interactive
	      A built-in multiplexer. interactive supports running commands on a subset of the connected hosts in parallel

       screen(1)
	      Runs ssh interactively inside screen. ~/.screenrc will be sourced if it exists.

       tmux(1)
	      Runs ssh interactively inside tmux.

       macterm (Mac OS X only)
	      Opens  a	Terminal.app  window and creates a tab for each ssh session. You must install the rb-appscript gem before you can use this
	      option.
