Ok I am really lost here

[fsanchez13]

I am trying the following

nohup telnet 10.10.10.10 1003 > /home/myfile &

and everytime I exit it kills the telnet. I thought nohup was suppose to allow me to run a command and then be able to logout without the command being killed? Am I lost on this or just doing someting wrong?

Why not use rsh (or remsh or rcmd, depending of your *nix flavor) ?

telnet is funny like this.....

have you thought of using something like expect to control the telnet session?

I wouldn't begin to know how to use expect for this function. The down and dirty is that I need to create a connection that can stay up for 24hours and log everything that comes across to the machine that is initiating the connection. This also has to be done through cron since the connection needs to establish every morning at midnight and start a new log file. Any clues on how I can do this?

Do you have expect installed? If so, try modifying this:

#!/usr/bin/expect -f

if {$argc==0} {
    send_user "usage: $argv0 host1\n"
    exit
}

set timeout -1
spawn telnet [lindex $argv 0]
match_max 100000
expect -exact "login:"
send -- "userid\r"
expect -exact "assword:"
send -- "password\r"
expect -exact " \$ "
send -- "date\r"
expect -exact " \$ "
send -- "sleep 6\r"
expect -exact " \$ "
send -- "date\r"
expect -exact " \$ "
send -- "exit\r"
expect eof

You should be able to run that safely in the background, redirecting the output to a file. Replace the commands with whatever you need (or delete them if none are required), and replace the " \$ " with a string that matches the command prompt on the remote host.
