Do you have ACPI enabled? Could it be that the system is throttling the CPU under load -- perhaps to keep the CPU cool? Possibly, but I have not had any further problems once it started working again. I have it configured as I want it, so I won't worry about it until it happens again. I have noticed sendmail blocking as I send a message through mutt. I presume this is caused by dns lookups, but it is nearly always brief. strace still blocks if I just say: $ strace cat file It blocks, but will jump start if I 'ctrl+z' and 'fg'. ioctl(3, PIOCWAIT Cory -- Cory Petkovsek Adapting Information Adaptable IT ConsultingTechnology to Your (858) 705-1655 Business [EMAIL PROTECTED] www.AdaptableIT.com ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: GPL: implications for FreeBSD-on-hardware for sale?

Are there any implications arising from the GPL (or other more-restrictive-than-BSD licensed) code in the tree? You are allowed to charge for GPL software. Look at redhat, suse, etc. What the GPL requires is that any GPL software you distribute, you must provide the source code and the same rights you have under the GPL (get source, modify, redistribute). Would it be arguable that I was, in fact, selling only the hardware and my own software application, and giving away the (GPL- and BSD-licensed) open source software for free? You don't need to argue. You can sell your own GPL software for $500, but you need to provide the GPLed source and the redistrib/modify rights. Your own proprietary binaries you can distribute along side the GPL and BSD code, provided you don't have GPL code within your programs. It can all be bundled together as long as you have licensing, copyrights and required source as part of the package (or possibly available, but not part of the package).

Re: remote install of freebsd via ssh
From: Brian Sent: April 8, 2004 05:21 Hello, Is there a way (or what is the best way) for installing freebsd remotely? I have a nontechnical person at the site that can put in a cd or enter a few commands, but the thought of walking through a full install via the phone is not fun. I would prefer to be able to use ssh for configuring. Any suggestions would be a great help. Burn a freesbie[1] and mail it to them. Have them boot up in it. Have them start sshd if it isn't. You can log in and take over.

Looking for something with a good how to .. ;-) First pick a package, then worry about a howto. Openwebmail is nice, it reads mail directly off of the mail spool. However it only works with mbox format. If this doesn't mean much to you it's not a big deal. Squirrelmail is also good but works through an imap server. This means it is independent of the underlying format, but it is slower.

In the interests of eliminating the obvious: you have confirmed that this is not some sort of DNS timeout? Delays of that length on starting up sendmail are usually due to waiting out the DNS timeouts. Would dns timeouts affect mailq? My dns is setup correctly locally, which is where I was trying to send my tests, to my local mailhub. What is also interesting is that it has started working again at a normal speed, without any changes or restarts. It was slow over config changes, make world, and reboots. But became slow, then became normal just by sitting idle. I have a p4 with HT and an SMP/HT kernel. Could that have anything to do with it?

sendmail/strace hanging
I'm running the 5.2 branch, last updated about 3/23-28. Last night I was working on forwarding sendmail on my freebsd workstation to my solaris mailhub. I modified my rc.conf to change: sendmail_enable=YES to sendmail_enable=NO sendmail_submit_enable=YES Then I worked on making a submit sendmail cf. I ran `sh /etc/rc.sendmail` and it restarted the daemons. Things worked fine. I could run mailq and sendmail as normal (aside from mail level problems). In the mean time I got side tracked with a solaris problem. I left that root window open and tackled solaris. When I came back to that window, things were not working quite right. `mailq` delayed for about 1min 15 seconds before displaying anything. It took about as long to send a message `echo test|sendmail cory`. Prompt comes back, but the process sits there for some time. Stopping sendmail with `sh /etc/rc.sendmail stop` works quickly. Starting it takes about 3min. Both sendmail-submit and sendmail-clientmqueue take a while before moving. Booting also has this delay. I have since commented out both sendmail lines in the rc.conf. I've also reset the sendmail configuration in /etc/mail. I did a cvsup with src-alll tag=RELENG_5_2 and did a make build/installworld last night. Still have the delay. Mergemaster replaced sendmail.cf, but saw no difference with rc.sendmail. Now for the fun part. I installed strace to see what was going on. Strace exibited similar blocking! ARRGGHH! doing an `strace ls` on one window and an `strace -p` in another shows it blocking at ioctl(3, PIOCWAIT If I hit ctrl-z and then `fg` on the `strace ls` window it instantly runs. If I `strace mailq`, again it blocks. `strace -p` in another window shows same thing. Doing a ctrl-z/fg makes it go and I get a bunch of output followed by this at the end: execve(/usr/libexec/sendmail/sendmail, [], [/* 0 vars */]PIOCWSTOP: Input/output error If I `mailq` and strace -p while it blocks I see it waiting at: kevent(0x3, 0xbfbfbcc0, 0x1, 0xbfbfbcc0, 0x1, 0xbfbfbca0 with a wchan of kqread. What happend?
