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 of problem:
It is not possible to connect to a tigervnc-server via IPV6
Version-Release number of selected component (if applicable):
1.2.80-0.30.20130314svn5065.el7
How reproducible:
/usr/bin/vncserver :1
netstat -an |grep 5901
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN
there is no tcp6 Entry in the List
Steps to Reproduce:
1.
2.
3.
Actual results:
Expected results:
netstat -an |grep 5901
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN
tcp6 0 0 :::5901 :::* LISTEN
Additional info:
It exists already a IPV6-patch for tigervnc-server
http://sourceforge.net/p/tigervnc/feature-request-tracker/_discuss/thread/74b73998/a2d1/attachment/tigervnc-ipv6.patch
For testing Xvnc:
1. IPv4+IPv6
2. IPv4-only on interface (e.g. ifconfig lo del ::1 for localhost) but host is IPv6 capable
3. IPv6-only on interface (e.g. ifconfig lo del 127.0.0.1) but host is IPv4 capable
4. IPv4-only (boot with ipv6.disable=1)
A. Start Xvnc with -localhost, check that correct address(es) are bound
B. Start Xvnc without -localhost, check that correct address(es) are bound
Need to check above matrix 1,2,3,4 x A,B.
For testing vncviewer:
1. Try numeric IPv6 address, e.g. '[::1]:1'
2. Try numeric IPv4 address
3. Try IPv6 DNS name (localhost, adjust /etc/hosts)
4. Try IPv4 DNS name (localhost, adjust /etc/hosts)
Check connections are to correct addresses with netstat -tn.
