Hello,

My name is Daniel, i am evaluating Splunk to be used as a part of a SOC but i haven't been able to configure linux boxes (Debian) to send their log information to my splunk server, i've already set up a port to listen to on the server side, but haven't been able to make the clients send their logs in, can you please help me?

You have 3 methods :

Use syslog, and configure your linux boxes to send their syslog events to the indexer on the UDP port you opened. Variation : using rsyslog or syslog-ng to use TCP instead of UDP, and use another port than default 514.
On the indexer : enable input on UDP or TCP on the port used
Remark : on unix box, only root processes can listen to the port under 1024,
see http://docs.splunk.com/Documentation/Splunk/4.3.2/Data/Monitornetworkports
please read your syslog service configuration to specify the destination server/port

OR

Install an UniversalForwarder on each boxes to monitor the log files (/var/log/ folder usually) and forward to the indexer on the port splunktcp
On the indexer : enable receiving in the manager.
see http://docs.splunk.com/Documentation/Splunk/4.3.2/Deploy/Aboutforwardingandreceivingdata
and http://docs.splunk.com/Documentation/Splunk/latest/Data/Monitorfilesanddirectories

OR

A mixed configuration is to setup a syslog server that is receiving all the syslog event, then write to disk in files, and have splunk monitor those files.

Please, don't take it the wrong way, but how does that information help in setting up a unix server TO SEND syslog data over to a splunk box?

@mendesjo ,the information provided about what you can do to send log information is the key. The actual process of setting up syslog to send data should be trivial.

Probably.. if you know unix. But since we don't that's why he's asking.
