blocking telnet

You can block outgoing telnet to a specific host from your machine by blocking data that's going out of your machine to that external host' port 23. If you are using Linux and iptables, you can use this

iptables -A OUTPUT -d <ip-of-blocked-host> --dport 23 -j DENY

If you are using Solaris, then you can do the blocking with ip filter.

NAME
Net::CLI::Interact::Transport::Telnet - TELNET based CLI connection VERSION
version 1.121640 DECRIPTION
This module provides a wrapped instance of a TELNET client for use by Net::CLI::Interact. INTERFACE
app On Windows platforms you must download the "plink.exe" program, and pass its location to the library in this parameter. On other platforms, this defaults to "telnet". runtime_options Based on the "connect_options" hash provided to Net::CLI::Interact on construction, selects and formats parameters to provide to "app" on the command line. Supported attributes: host (required) Host name or IP address of the host to which the TELNET application is to connect. reap Only used on Unix platforms, this installs a signal handler which attempts to reap the "ssh" child process. Pass a true value to enable this feature only if you notice zombie processes are being left behind after use. COMPOSITION
