Bug 471874 – net-analyzer/wireshark-1.8.7 - enewgroup should be run before merge phase

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description thetuber 2013-05-31 05:14:43 UTC]

When I install wireshark, and the group wireshark does not exist, there are permission problems that prevent non-root users from running wireshark (even users in the wireshark group can't run it). The error in wireshark is:

No interface can be used for capturing in this system with the current configuration.
(Couldn't run /usr/bin/dumpcap in child process: Permission denied)

The permissions on /usr/bin/dumpcap are:

-rwxr-x--- 1 root root 80K May 30 21:29 /usr/bin/dumpcap*

Even if I change the group to wireshark, it doesn't work. I get just the message:

No interface can be used for capturing in this system with the current configuration.

Now if I unmerge wireshark, leave the wireshark group in /etc/group, then emerge wireshark again, everything works. The permissions on /usr/bin/dumpcap are also correct.


Reproducible: Always

Steps to Reproduce:
1. Ensure that the wireshark group does not exist.
2. emerge wireshark.
3. Run wireshark as non-root user in the wireshark group. Will not be able to capture packets.

Actual Results:  
Unable to capture packets with the error message:

No interface can be used for capturing in this system with the current configuration.

(Couldn't run /usr/bin/dumpcap in child process: Permission denied)


Expected Results:  
Should be able to capture packets.

Exact same problem here but in net-analyzer/wireshark-1.10.0_rc2, also reinstall solves it.

Salud.
