Hey guys,<br />
So trying to figure out if there is a way in tcpdump to only capture 2 protocols.<br />
We are trying to capture SIP and RTP. &nbsp;<br />
We cannot really specify port since the RTP can be 10000-20000<br />
<br />
Is there a way to tell it something like protocol=sip &amp;&amp;&nbsp;protocol=rtp?<br />
<br />
or does tcpdump not have the inteligence to know what protocols go with what ports?<br />
<br />
If it doesn't how could i write a filter that inclues 5060 and 10000-20000<br />
<br />
Thanks!

CentOS tcpdump to capture only a specific protocol.

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
