Red Hat Bugzilla – Bug 292101
SETroubleshoot examples show wrong commands
Last modified: 2008-06-16 22:24:14 EDT
Description of problem: When changing apache from 80 to a user specified port,
setroubleshoot pops up with the avc denial. However the example commands are wrong.
Version-Release number of selected component (if applicable):
[pgraner@zorak ~]$ rpm -q setroubleshoot
How reproducible: 100%
Steps to Reproduce:
1. edit httpd.conf and change the line: Listen 80 to Listen 2112 (or any other port)
2. restart the apache service. service httpd restart
3. Watch setroubleshoot pop up.
4. Read the text. The two example commands are wrong:
semanage port -L should be semanage port -l
semanage port -a -t PORT_TYPE 2112 should be semanage port -a -t PORT_TYPE -p
in fact it could be a bit smarter rather than giving PORT_TYPE, it would be nice
if the troubleshooter could dertermine what service was trying to access the
port and in this case give the example of:
semanage port -a -t http_port_t -p tcp 2112
Thanks for the report. Fixing the the -l is easy. I think we can probably map
the port types, I'll look into it...
I have fixed the message to at least specify -p PROTOCOL in the upstream code.
Figuring out the port type is a little more difficult, By convention there is a
usually a match between types, httpd_t and httpd_port_t. So we could truncate
httpd_t to httpd and check if there is a httpd_port_t, if not we go with the
One other problem though is that setroubleshoot currently can not run semanage
or read the policy info to get this data, SELinux is preventing it.
ports = seobject.portRecords().get_all()
if setype[-2:] == "_t":
setype = setype[:-2]
test = "%s_port_t" % setype
# Attempt to truncate "d" and see if you get match
test1 = "%s_port_t" % setype[:-1]
for i in ports:
if ports[i] == test:
if ports[i] == test1:
Will attempt to match a port type.

This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.
Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008.
Fedora 7 is no longer maintained, which means that it will not
receive any further security or bug fix updates. As a result we
are closing this bug.
If you can reproduce this bug against a currently maintained version
of Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
