Please clarify, what would you like to do?

Not from nohup, you don't want to use nohup nor & when waiting for the perl process to end.
The perl script should output something on the standard output when its job is done; if it is completely silent, at least the remote shell should output a prompt. If you were to telnet manually you would see that output on your terminal screen. Since your shell script is using telnet, not you, it is your script that has to
read from the two-way pipe (|&) and decide if and when the perl script is finished.

Of course the file nohup.out is created on the remote machine, and more precisely in the current directory for the nohup process, and that directory happens to be the home dir of $USERID (since I see no cd commands).

jifty::script::server
Jifty::Script::Server(3pm) User Contributed Perl Documentation Jifty::Script::Server(3pm)
NAME
Jifty::Script::Server - A standalone webserver for your Jifty application
SYNOPSIS
jifty server
jifty server --port 6666
jifty server --stop
DESCRIPTION
Starts and stops Jifty's standalone web server.
options
--port The port to run the server on. Overrides the port in the config file, if it is set there. The default port is 8888.
--user USER
The user to become after binding to the port. It is advised that you use this when binding to low ports, instead of running as
"root". This option only works if the server is using a Net::Server subclass.
--group GROUP
The group to become after binding to the port. Like "--user", this option only works if the server is using a Net::Server
subclass.
--host HOSTNAME
The host to bind to. This option only works if the server is using a Net::Server subclass.
--stop Stops the server, if it is running. This is accomplished by reading the PID from "var/jifty-server.pid"
--restart
restart the server, if it is running. This is accomplished by killing the child pid, and let parent pid create a new one
--sigready SIGNAL
Sets the signal number that should be sent to the server's parent process when the server is ready to accept connections.
--quiet Reduces the amount of debug output sent by the server
--dbiprof
Turns on DBI profiling; see DBI::ProfileDumper.
--help Print a brief help message and exits.
--man Prints the manual page and exits.
DESCRIPTION
When you're getting started with Jifty, this is the server you want. It's lightweight and easy to work with.
METHODS
run
"run" takes no arguments, but starts up a Jifty server process for you.
