Prior to this update, the collected netstat output truncated IPv6 addresses, preventing users to see complete IP address of listed connections. With this update, the gathered command prints output in a wide format, thus with complete IPv6 addresses.

Description Martin Poole 2015-12-08 12:39:01 EST
Description of problem:

netstat -neopa data truncates IPV6 addresses

Version-Release number of selected component (if applicable):


Additional info:

command needs additional of -T to ensure full addresses are captured.
Comment 1 Bryn M. Reeves 2015-12-08 12:58:26 EST

-T is not documented in the netstat man page or usage text and attempting to add it causes an invalid option error:

    [root@bmr-rhel7-vm1 ~]# netstat -neopaT
    netstat: invalid option -- 'T'
    usage: netstat [-vWeenNcCF] [<Af>] -r         netstat {-V|--version|-
           netstat [-vWnNcaeol] [<Socket> ...]
           netstat { [-vWeenNac] -I[<Iface>] | [-veenNac] -i | [-cnNe] -M | -s 
           [-6tuw] } [delay]

None of the netstats on my Fedora or RHEL boxes have heard of this switch.

# rpm -q net-tools

Is this a new option? If so we'd need to know what version it appears in in order to not trigger errors on older installations (although to be honest the idea of a "please don't trash IP addresses on output" switch to a net-tools command seems a bit crazy just out the gate..).

It would also be helpful if you could include full steps to reproduce or the output that you are seeing - I don't see any truncation when running this command with the default IPv6 settings on an el7 install.

Oh joy.

On RHEL7 it's -W, on RHEL6 and earlier it's -T
