Fixed In Version: tcpdump-4.0.0-5.20090921gitdf3cb4.2.el6 Doc Type: Bug Fix
Doc Text:
Cause: tcpdump was treating argument for -i option as a number if it had numeric prefix. Consequence: Packet capturing wasn't started at all on specified interface or it could get started on wrong interface. Fix: Treat the argument to -i options as a number if it's *all* number. Thus interface names such as 192_1_2 aren't treated as interface number 192. Result: tcpdump should start correctly on specified interface even if interface name has numeric prefix.

Comment 4 RHEL Program Management 2013-10-13 23:29:54 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.

Comment 5 Guy Harris 2014-01-07 21:17:06 UTC
tcpdump 4.3 and later use strtol() in that fashion; what version of tcpdump is in RHEL 6?  Is this bug really requesting that the change made in tcpdump 4.3 be backported to an older version of tcpdump?

Comment 6 Michal Sekletar 2014-01-09 15:05:15 UTC
If everything goes as planned then tcpdump will be rebased in next version of RHEL and this bug should be fixed by rebase. Anyway, Guy thank you very much for taking the time to look at this, very appreciated.
