Lo mejor es implementar algún sistema que dote de interactividad a las
sesiones, cosas parecidas hemos hecho nosotros con:
a) expect solución sencilla y recurrida si no tienes perl
debbie:~# apt-cache show expect
Package: expect
Priority: optional
Section: interpreters
Installed-Size: 456
Maintainer: Mike Markley <mike@markley.org>
Architecture: i386
Version: 5.32.2-4
Replaces: expect5.31 (<< 5.31.8-4), expect5.24 (<< 5.30.1-8)
Depends: libc6 (>= 2.2.3-7), tcl8.3 (>= 8.3.0)
Suggests: expectk
Conflicts: expect5.31 (<< 5.31.8-4), expect5.24 (<< 5.30.1-8)
Filename: pool/main/e/expect/expect_5.32.2-4_i386.deb

Description: A program that "talks" to other programs.
Expect is a program that "talks" to other interactive programs
according to a script. Following the script, Expect knows what
can be expected from a program and what the correct response
should be. An interpreted language provides branching and high-
level control structures to direct the dialogue. In addition,
the user can take control and interact directly when desired,
afterward returning control to the script.
b) perl
debbie:~# apt-cache search "perl" | grep -i telnet
libnet-telnet-perl - Script telnetable connections
debbie:~# apt-cache show libnet-telnet-perl
Package: libnet-telnet-perl
Priority: optional
Section: interpreters
Installed-Size: 196
Maintainer: Michael Alan Dorman <mdorman@debian.org>
Architecture: all
Version: 3.02-1
Depends: perl5
Filename: pool/main/libn/libnet-telnet-perl/libnet-telnet-perl_3.02-1_all.deb
Size: 48958
MD5sum: 2b2e921ba969d5a2176a6c403a713bed
Description: Script telnetable connections
Net::Telnet allows you to make client connections to a TCP port and
do network I/O, especially to a port using the TELNET protocol.
Simple I/O methods such as print, get, and getline are provided.
More sophisticated interactive features are provided because
connecting to a TELNET port ultimately means communicating with a
program designed for human interaction. These interactive features
include the ability to specify a timeout and to wait for patterns to
appear in the input stream, such as the prompt from a shell.
