Hey all, I'm very new to expect. I'm trying to automate creating a default password for a user using expect. Here's what I'm trying to do:
Connect to remote systems via ssh. The system has a trusted key, so no password is required for log in.
Invoke the password command for the user
Input password
Input password again
Exit.
I'm not sure why, but when the passwd command invokes, it does so on the local, and not remote host. Looking at the debug (see below script) I can see that I do spawn the ssh session to the remote host, I'm just not sure why the spawn of passwd is happening on the local rather than remote host.
Thanks in advance for the help! Any other comments or advice on making this more robust would be appreciated as well.
Here's the script:
#!/opt/freeware/bin/expect -f
# Useage login site
if { $argc < 1 } {
send_user "Usage: prog host user \n"
exit
}
set host [lindex $argv 0]
set user [lindex $argv 1]
set password testpass
set prompt "# "
spawn ssh $host
expect $prompt
spawn /usr/bin/passwd $user
expect "password:"
send -- "$password\r"
expect "Enter the new password again:"
send -- "$password\r"
send "\n\n"
exit
Here's the debug output
