[Bug 253437] New: fam has no address, rejected by xinetd, when called from courier-imap
https://bugzilla.novell.com/show_bug.cgi?id=253437 Summary: fam has no address, rejected by xinetd, when called from courier-imap Product: openSUSE 10.2 Version: Final Platform: x86-64 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: andrew@acooke.org QAContact: qa@suse.de Hi, I use courier-imap. It expects famd to be running (I think it uses it to detect when new mail has been delivered to a Maildir directory). If fam is not running it still works, but is slower, a but unreliable (doesn't detect changes quickly) and logs errors complaining about a missing fam. These are the associated messages from /var/log/mail: Mar 11 19:01:51 quiet imapd: Failed to create cache file: maildirwatch (andrew) Mar 11 19:01:51 quiet imapd: Error: Input/output error Mar 11 19:01:51 quiet imapd: Check for proper operation and configuration Mar 11 19:01:51 quiet imapd: of the File Access Monitor daemon (famd). If I install fam-server and start fam via xinetd the the services start OK. However, I see the following errors in /var/log/xinetd.log: 07/3/11@18:48:50: START: fam from=<no address> 07/3/11@18:48:50: EXIT: fam status=0 duration=0(sec) 07/3/11@18:48:50: FAIL: fam address from=<no address> 07/3/11@18:48:50: START: fam from=<no address> 07/3/11@18:48:50: EXIT: fam status=0 duration=0(sec) 07/3/11@18:48:50: FAIL: fam connections per second from=<no address> and the results of that in /var/log/messages: Mar 11 18:58:32 quiet xinetd[4735]: Deactivating service fam due to excessive incoming connections.

Restarting in 10 seconds. Mar 11 18:59:48 quiet xinetd[4735]: Activating service fam (I haven't tried to match the lines by time). Note that everything is running on localhost. Googling around for a solution I found the problem and fix described at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=108583 However, flags=NOLIBWRAP does not fix the problem and flags=NO_LIBWRAP gives an error starting xinetd. Also, I have run this config before and (i) I don't recall problems on 10.2 or 10.1 and (ii) you hae never had fam marked as a er -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=253437 ------- Comment #1 from andrew@acooke.org 2007-03-11 16:17 MST ------- Eeek. Somehow submitted this via the keyboard while still typing. Was going to finish by saying: ...(ii) you have never had fam marked as a required dependency for courier-imap, when you probably should since it logs errors and works less well if not running) Thanks, Andrew -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

(2) I think you are asking about dependencies? courier-imap requires lib-fam, but not fam-server. It is fam-server that contains famd, which runs inside xinetd, and which does not work. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=253437 ------- Comment #6 from andrew@acooke.org 2007-03-14 07:56 MST ------- Ah, thanks. Looking again at what I wrote I guess it's not very clear. The main problem here is that courier-imap uses the fam service (implemented by famd, called via libfam), which runs inside xinetd. When courier-imap tries to use this service, however, xinetd rejects the use as insecure. The problem seems to be related to xinetd not finding any address (which should be "localhost", I assume) associated with the call, perhaps because of a problem with libwrapper. Hope that helps - thanks for looking at this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
