Hi Jeff,

I must be missing something.

I set dumpcap permissions to:

# ls -l /usr/local/bin/dumpcap
-rwxr-xr-- 1 root wireshark 230157 Dec 11 10:40 /usr/local/bin/dumpcap

and the dumpcap command is:

root             /usr/local/bin/dumpcap -B 16 -i 2 -f vlan and (not vrrp and not udp port 1985 and not ether host 01:00:0c:cc:cc:cc) -g wireshark -b filesize:250000 -b duration:900 -w /var/opt/data/captures.cap

I also tried

root                        /usr/local/bin/dumpcap -B 16 -i 2 -f vlan and (not vrrp and not udp port 1985 and not ether host 01:00:0c:cc:cc:cc) -g -b filesize:250000 -b duration:900 -w /var/opt/data/captures.cap

but the ring buffer files still end up "root root".

]# ls /var/opt/data/captures/*  -l
-rw-r-----  1 root root      111542192 Dec 11 13:19 /var/

Thoughts??

Any guidance will be appreciated!

Thanks!

-John

Hi,

I need to set the group permissions for files created by DumpCap.

In this post I see the option " -g " is supposed to exist (http://www.engardelinux.org/modules/index/list_archives.cgi?list=wireshark-users&page=0016.html&month=2010-09 <http://www.engardelinux.org/modules/index/list_archives.cgi?list=wireshark-users&page=0016.html&month=2010-09>)

Can someone please point me to how I can get a version that to have access to this option?

You'd need Wireshark 1.6.0 or later.  The current version (1.8.4) would be your best bet.

BTW I noticed that this option is not listed in dumpcap's man page; I'll correct that shortly.
