#!/bin/sh
telnet 10.161.240.2 8100
<?xml version=\"1.0\"?> <login_command><sequence id=\"1\" /> <access id=\"1\"/> <user name = \"ttmlcnms\" password = \"cnms#123\"/> </login_command>
<?xml version=\"1.0\"?> <RegistrationDescriptor><sequence id=\"1\" /> <access id=\"1\"/> <attributeDescriptors><action>Register</action> </attributeDescriptors> </RegistrationDescriptor>

I don't think you can run telnet like that. What type of system is the telnet server you're trying to connect? The traditional method of automating telnet sessions is to use a .netrc file or an expect script. The connection is closed because after the telnet command.

I've used this silly method on occasion to keep the session open but as Joe says I think use "expect". I've also tried "empty.sourceforge.net" which perhaps has a smaller foot print than "expect".
mknod pipe p # create a named pipe
# sleep to keep the session open
exec 1> trace_file
( sleep 300 > pipe;
print -u2 "Exceeded time limit.\r;
kill -9 $$" ) &
PIPE_MASTER_PID=$!# telnet in the background
telnet -e vt100 hostname < pipe 2> error_file &
TELNET_PID=$!while :; do
sleep 1
egrep -q "login:" trace_file
if [[ $? -eq 0 ]]; then
print us > pipe
fi
egrep -q "password:" trace_file
if [[ $? -eq 0 ]]; then
print password > pipe
fi# When you're done
# kill -9 $PIPE_MASTER_PID
# kill -9 $TELNET_PID
done
