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:
When we configure Xvnc server, it by default listen for connections for a VNC client on TCP ports 5800+x, 5900+x, and 6000+x. If I update tigervnc-server package to tigervnc-server-1.1.0-18.el6.x86_64, it stops listening on 6000+x TCP port. Which was not the default behavior with tigervnc-server-1.1.0-16.el6.x86_64.
Version-Release number of selected component (if applicable):
tigervnc-server-1.1.0-18.el6.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Install tigervnc-server-1.1.0-16.el6.x86_64 package and run Xvnc server on RHEL6 system and check if system is listening on TCP port 60XX:
# vncserver :99
# ss -nlt
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:59977 *:*
LISTEN 0 50 *:9102 *:*
LISTEN 0 5 *:5999 *:*
LISTEN 0 64 *:40175 *:*
LISTEN 0 128 *:111 *:*
LISTEN 0 128 *:6099 *:* <<=====
LISTEN 0 128 *:22 *:*
2. Stop Xvnc server and update tigervnc-server to tigervnc-server-1.1.0-18.el6.x86_64
$ vncserver -kill :99
# yum update tigervnc-server
3. Restart Xvnc process and check TCP port 60XX status:
$ vncserver :99
$ ss -nlt
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:59977 *:*
LISTEN 0 50 *:9102 *:*
LISTEN 0 5 *:5999 *:*
LISTEN 0 64 *:40175 *:*
LISTEN 0 128 *:111 *:*
LISTEN 0 128 *:22 *:*
Actual results:
After updating tigervnc-server-1.1.0-18.el6.x86_64, it stops listening on 6000+x TCP port.
Expected results:
It should listen on 6000+x TCP port.
