1289679 – sos netstat capture truncates IPV6 addresses

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Martin Poole 2015-12-08 17:39:01 UTC

Description of problem:

netstat -neopa data truncates IPV6 addresses

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

sos-3.2-35.el7

Additional info:

command needs additional of -T to ensure full addresses are captured.

Comment 1 Bryn M. Reeves 2015-12-08 17:58:26 UTC

Really?

-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|-
    h|--help}
           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
net-tools-2.0-0.17.20131004git.el7.x86_64

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.

Comment 2 Martin Poole 2015-12-08 18:06:50 UTC

Oh joy.

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