hi,
i have many Proxmox servers with a lot of VMs. I want to use expect to connect
to the VMs via serial console (qm terminal <vm_id>), and check if I need to
login (expect "login: "), or if someone forgotten to logout and I have already
a prompt and I need to send an exit before and than try to login again.
My very first expect script looks like:
==============
#!/usr/bin/expect -f
### Setting basics
# Show commands and output
log_user 1
# Set variable
set user root
set password testpass
set name [ exec hostname -f]
set prompt ": "
spawn qm terminal 101
#expect_before ": " {
# send "exit\r"
#}
expect "login: "
send "$user\r"
expect "password:"
send "$password\r"
expect $prompt
puts "---------- $name START ---------"
expect $prompt
send "hostname -f\r"
expect eof
puts $expect_out(buffer)
expect $prompt
send "cat /etc/debian_version\r"
expect eof
puts $expect_out(buffer)
expect $prompt
expect eof
send "sed -i 's/root:\ nobody/root:\ sys...@example.com/g'
/etc/aliases;newaliases\r"
expect $prompt
puts "--------- END -------"
expect $prompt
send "exit\r"
expect "login:"
send "\x1o\r"
================
it works, if I need to login first, but if I have a shell, I want to send an
"exit" before and (re)login again.
The next point is: expect is very slow ... it seems, that there is a default
delay .... every command needs 10 seconds :-) Can I remove the delay or make it
shorter ?
