Hi,
Port 514 is the port for the syslog service, as you seem to have already determined. However, in those instances where a local logging service is configured to listen for incoming connections on port 514 it almost always uses UDP rather than TCP, so you can't test this by attempting to telnet to the port.
Exactly how you'd configure this all to work depends on your exact version of UNIX/your Linux distribution, what software you're using for logging, and of course if there is some external firewall that could be in the way even if your own local firewall definitely is not. But the best way to test it is to try to generate a logged event on a remote system that you have configured to log to your syslog server, and see if something gets logged or not.

net::cli::interact::transport::telnet
Net::CLI::Interact::Transport::Telnet(3pm) User Contributed Perl Documentation Net::CLI::Interact::Transport::Telnet(3pm)
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
See the following for further interface details:
