Description:

Right now, to capture any packets, wireshark must be run as root. This isn't necessary if wireshark's dumpcap binary is installed in a certain way.

The wireshark package should create a wireshark group and install dumpcap as owned by root:wireshark with permission bits 6750. This would allow members of the wireshark group to capture packets in wireshark. This is done in Gentoo's wireshark package and seems like a good idea.

This sounds pretty good to me.

Does anyone object to this setup?

Looks like we can't do this until the groupadd bug with shadow is resolved.

Before we install it as setuid-root, we should consider running "setcap cap_net_raw+ep /usr/bin/dumpcap" instead in a post_install. This will have the same effect, with less potential security implications.

It should still only be allowed for a restricted group.

In Feb 2010, I took the next step on the dependent bug. Once that's sorted out, will revisit this in March 2010.

With the bug closed for the issues with GIDs in shadow, it sounds like we could do a wireshark group, install dumpcap as root:wireshark with 0750 and also do the setcap that Thomas suggests, for extra security.
