Re: Sendmail waiting?
Thanks for the help - there is a fix in there somewhere :-) Saw this in cvs-commit: Modified files:(Branch: RELENG_5_0) sys/fs/fifofsfifo_vnops.c Log: MFC: Put a one-second timeout (And a XXX: comment) on a tsleep which under certain not understood circumstances hangs sendmail during boot. Looks like there might be a bug somewhere in my system, too. Might explain the intermittent naure of the problem? -- Brian To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

That still wouldn't identify the cause, though. :-( I assume that your ADSL provider uses PPPoE -- how to you fire up your PPP interface at boot? I do this in /etc/rc.conf, which forces ppp to establish a connection before progressing with the boot, which means that the net connection is up by the time sendmail is started: # PPP ppp_enable="YES" ppp_profile="HSE" ppp_mode="ddial" -- Matt Emmerton To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

I don't switch off every day, but I have noticed that, on restart, loading sometimes waits "for ever" at "installing standard daemons" sendmail. Last night the wait was 2 full minutes, and the effect was for me not to be able to get X and worse - "getty repeating too fast - sleeping for 30 seconds" During that sleep, I could work from the console normally, but then the screen blanked and fluttered for several seconds before the sleeping phase was again reimposed. This morning - not expecting too much - I switched on and this time loading swept past sendmail without delay and everything is working normally again. I do not propose to switch off for some time. :-) Q1. Can anyone suggest any explanation for the sendmail-wait problem and subsequent horrors? Q2. I am cvsupping and ready to update to the latest stable. Is this sound, and is it in any way likely to resolve my problem with v 4.6 RELEASE? My experience is that if your network goes down or DNS cannot easily resolve your name, sendmail will pause for a bit. I believe installing a caching(sp) name server on the box will probably help out. I cannot remember the command to install it, so check the archives, but it is really simple. Michael K.

Thanks, guys - but why would this be an intermittent problem? And - why would it affect my access to X? The Good Lord knows what was going on last night with the repeating getty! :-) Everything is just fine, now - my real problem is how can I keep it that way? That of course requires my identifying the cause. One clue - I recently went broadband with an ADSL modem and that modem is set up as my default gateway. It is a Netcomm NB1300. That caching name server idea sounds good. I will have a search on FBSD org for that. That still wouldn't identify the cause, though. :-( -- Brian To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
