How can I run telnet inside a shell script and execute commands on the remote server?
I do not have expect installed on my solaris machine because of security reasons.
I also do not have the perl net::telnet
module installed.
So with out using expect and perl how can I do it?
I tried the below thing but its not working.
#!/usr/bin/sh
telnet 172.16.69.116 <<!
user
password
ls
exit
!
When I execute it, this is what I am getting:
> cat tel.sh
telnet 172.16.69.116 <<EOF
xxxxxx
xxxxxxxxx
ls
exit
EOF
> tel.sh
Trying 172.16.69.116...

Some of your commands might be discarded. You can achieve finer control with ordinary script constructs and then send required commands through a pipe with echo
. Group the list of commands to make one "session":-
{
sleep 5
echo user
sleep 3
echo password
sleep 3
echo ls
sleep 5
echo exit
} | telnet 172.16.65.209
