Expect Custom Script - SLC Device Port Session
An example of an Expect Custom Script that interacts with a SLC Device Port (in this example a
ServerTech PDU is connected to a Device Port):
#! expect
#
# Script to get the load of a ServerTech PDU outlet
#
set pduPrompt ">"
set pduLoad "unknown"
proc myprint {str} {
send_user -- "$str\n"
}
proc abortSession {err} {
send_user "Error $err. Terminating session.\n"
exit $err
}
set now [clock seconds]
set date [clock format $now -format {%D %R}]
myprint "Load of ServerTech PDU outlet B1 at $date"
# spawn the port session on a device port
if {[catch {spawn -noecho portsession -p $devicePort} result]} {
abortSession 1
}
set sessionId $spawn_id
# Handle eof
expect_after {
-i $sessionId eof {
myprint "Session unexpectedly terminated."
abortSession 2
}
}
set timeout 10
log_user 0
#
# Login to the PDU
# The "Error:*" pattern matches all error messages output by portsession
#
send "\n"
expect {
"Username:" { send "admn\n" }
"Error:*\r\n" { send_user $expect_out(0,string); abortSession 2 }
}
