Summary: [FC4 Regression]: spamc doesn't use localhost by default Product: Fedora Core Version: fc4 Platform: All OS/Version: Linux Status: NEW Severity: normal Priority: normal Component: spamassassin AssignedTo: wtogami@redhat.com ReportedBy: hongjiu.lu@intel.com CC: fedora-perl-devel- list@redhat.com,felicity@kluge.net,jm@jmason.org,parkerm @pobox.com,reg+redhat@sidney.com,wtogami@redhat.com

I have

:0fw | /usr/bin/spamc

in /etc/procmailrc. It worked with FC3. But after upgrading to FC4, I got

Dec 10 08:38:45 ocean spamd[27833]: unauthorized connection from gate.in.lucon.org [192.168.10.1] at port 32823

My machine has

eth0 Link encap:Ethernet HWaddr 00:07:E9:9C:3E:3E inet addr:192.168.10.1 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::207:e9ff:fe9c:3e3e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5662 errors:0 dropped:0 overruns:0 frame:0 TX packets:5908 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1160392 (1.1 MiB) TX bytes:2571450 (2.4 MiB)

It looks like spamc is connecting to 192.168.10.1 instead of 127.0.0.1.

------- Additional Comments From hjl@gnu.org 2005-12-10 22:00 EST ------- I am using procmail + postfix. It used to work in FC3. If I run spamc by hand, it connects to localhost. But when it runs from procmail, spamc connects to eth0.

It looks a kernel bug. When spamc connects to 127.0.0.1, accepts returns with client from eth0:

I am running PPP over ethernet. eth1 doesn't have an IP address. kernel gets confused and return eth0 instead of lo.

------- Additional Comments From wtogami@redhat.com 2005-12-11 10:56 EST ------- Curious, can you re-test this after disabling ipv6? Same behavior?

Try adding "alias net-pf-10 off" to /etc/modprobe.conf and reboot. You can easily remove it later to enable ipv6 again.

The main difference is that my gateway has PPPOE.

------- Additional Comments From davej@redhat.com 2006-02-03 00:46 EST ------- This is a mass-update to all currently open kernel bugs.

A new kernel update has been released (Version: 2.6.15-1.1830_FC4) based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem.

This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed.

Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug.

If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613.

------- Additional Comments From davej@redhat.com 2006-09-16 22:38 EST ------- [This comment added as part of a mass-update to all open FC4 kernel bugs]

FC4 has now transitioned to the Fedora legacy project, which will continue to release security related updates for the kernel. As this bug is not security related, it is unlikely to be fixed in an update for FC4, and has been migrated to FC5.

Please retest with Fedora Core 5.

Thank you.

------- Additional Comments From davej@redhat.com 2006-10-16 14:47 EST -------

A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem.

This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed.

In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details.

If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613.

If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem.

Thank you.
