Why kill -9 has still no effects on some bad processes? Regards, -- Demelier David A process can be unkillable if it's holding a lock, like reading from disk. Eventually, the lock will release and it should die. You can use limits to change how much CPU and memory a process can use. My guess is what happened is it started using a lot of memory, but you ran out and have a lot of swap. It was trying to run while using your hard drive instead of ram. With limits, you should be able to prevent it from using swap which could help, and cap the amount of ram and cpu. Hello, thank you for that precise explanation, I will add limits into the new rctl.conf, however I don't know how many amount of ram I should allow, in fact I have absolutely no idea how much of ram an usual program eats, is 50Mo enough for user applications ?

MySQL hangs server completely
Hi, We've been having this problem with a customer for a while and it seems that some funky query makes MySQL use 100% of CPU. Nevertheless, even though you can see in top that it's only 1 CPU in 100% (out of 8) the server eventually becomes useless and stops responding completely. So my question is, how does a user process hang the whole server? What system resources could MySQL be draining to make the server stop responding completely? The MySQL database is running inside a Jail and perhaps that could help limit the damage it can cause. Has anyone else run into this problem? Thanks, -- Alejandro Imass ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

For Interface rl0 ipv6 address ifconfig_rl0_ipv6=inet6 fd8f:d6d0:e6e7:100::101 prefixlen 64 , what will be laptop ipv6 address? It depends solely on the operating system and whether IPv6 privacy is in effect. Normally, the client will perform stateless automatic address configuration (SLAAC). It goes pretty much like this: The router announces the 64 bit prefix, usually every 200 seconds, but the client may request a new announcement at any time. The client generates a 64 bit interface identifier based on its 48 bit MAC address. The client then concatenates the supplied prefix with the generated interface identifier. The client then performs duplicate address detection (DAD), and if everythings checks out, the client got its IPv6 address. Given this prefix fd8f:d6d0:e6e7:100::/64, and this MAC address 50:e5:49:41:4d:70. The client would then generated this interface id: 52e5:49ff:fe41:4d70. The Universal/Local bit of the MAC address is inverted, and FF:FE is placed at center. (It really ought to be FF:FF, but way back in time someone misread the IEEE standards regarding conversion from 48 bit MAC addresses to EUI64 format. This oversight doesn't really matter.) The same client would then aqcuire this IPv6 address: fd8f:d6d0:e6e7:100:52e5:49ff:fe41:4d70, and perform DAD. The client gets its IPv6 default route/gateway from the router announcement. Of course, you may configure the IPv6 address and gateway manually on the client, say fd8f:d6d0:e6e7:100::1337/64 (client's address) and fd8f:d6d0:e6e7:100::101 (gateway's address).

Keeping my system up to date with CTM or subversion?
I'm confused about an effective way to keep my system patched and up-to-date, and I'm hoping someone can clarify what seems like a lot of options. I'll be running a production server (so security and stability are most important) with a custom kernel and I want it to have all of the latest security patches applied. I'll install from DVD and I'll chose the option to install both the ports and the source. After this, it sure seems like the best way, in terms of speed to download any updated files, is to use CTM as a cron job, but I think the FBSD handbook recommends subversion? Also, I think I read that CTM won't update documentation? Is that right? I also see some people say they use portsnap, portaudit and portupgrade. For example, I came across this command: portsnap fetch /usr/sbin/portsnap update /usr/local/sbin/portaudit -F /usr/local/sbin/portupgrade –aR however these utilities are used more for keeping your ports collection up-to-date (if you install software from ports), and not so much for keeping your system patched from a security perspective - isn't that right?

With limits, you should be able to prevent it from using swap which could help, and cap the amount of ram and cpu. Hello, thank you for that precise explanation, I will add limits into the new rctl.conf, however I don't know how many amount of ram I should allow, in fact I have absolutely no idea how much of ram an usual program eats, is 50Mo enough for user applications ?

On Wed, 22 May 2013 13:23:39 -0700, Ed Flecko wrote: So once you have a system up and running, how do you monitor if and when you need to upgrade your ports tree? This highly depends on your updating policy. There are three mainstream opinions: a) always update, regularly (e. g. once a week) b) only update if security requires it (e. g. when portaudit alerts) c) update as soon as an additional functionality is desired Of course, combined opinions are also valid. :-) For updating the ports tree, portsnap is the eaiest tool. However, if you follow opinion a) and update _very_ regularly (e. g. daily), you could use SVN to obtain the (smaller) deltas to your local tree. This also helps because you can directly access the tree and don't have to wait until a snapshot is made available. For higher update frequencies, this is often the better approach. There is another valid opinion: Install once, make sure everything works, never touch a running system. I'm a big fan of this attitude, at least on my home systems. ;-) By the way, your ports tree is different than installed software packages, right? That is possible when you update your ports tree (by whatever method) _after_ you have installed something. A typical conclusion is that you might need to rebuild stuff as soon as you install something with that (newer) tree. Example: Tree is at version 12345, you install foo-1.0 which depends on bar-1.5. Two weeks later, you update your ports tree and get version 23456. You don't want to touch foo and bar, but you now need to install baz which requires bar-1.6 (which has now arrived in the tree). So now you need to update bar from 1.5 to 1.6, and _maybe_ also foo to a newer version (whatever that might be). In other words, the only reason people even bother to upgrade their ports tree is so that IF you install a package from source - the source is current? Is that correct? Maybe the wording is a bit strange, but yes, updating the ports tree means to have the lastest and _consistent_ versions of all the programs in the tree (so their interconnections will work properly). This is also helpful when you install from different sources, e. g. some stuff from source, some stuff as binary packages from Latest/. When security vulnerabilities are discovered and patches released by FBSD, the patch will tell you what steps you need to take to apply the patch and stay up to date, won't it? The OS patches are announced that way. You should always read the UPDATING files in /usr/src (for the OS) and /usr/ports (for installed applications) to make sure you're not missing a simple (but important) step during upgrades. Patches for the OS are of course handled independently from those applying to applications from the ports collection. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

thanks Michael, but in all documentation about journaling, tunefs is used as below: tunefs -J enable ad3s1X.journal. ad3s1X.journal is created by gjournal command: gjournal label ad3s1a ad3s1g that assign ad3s1g as journal provider for ad3s1a and create ad3s1a.journal which contains ad3s1a as data provider and ad3s1g as journal provider. my problem is, i can not run gjournal command for root partition in fixit mode nor single user mode. you mean, i should just use tunefs command on ad3s1X (root partition)? if yes, then where journal provider for root partition is located? in root partition?

No, but you don't need to. In single user mode, root is mounted read-only. You can run tunefs on the root fs device. - M ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Ah, sorry - lack of careful reading on my part. Can you boot from installation media and use the fixit mode? This still won't work if the last sector of the partition is in use by the filesystem You'll need a spare partition of some size to be the journal provider, as in the example. The very best approach is to create a gjournal and then newfs. How is your disk organized? One big root partition with everything on it? - M ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: setup journaling for root partition
thanks Michael for your quick reply:) yes, i can boot from usb freebsd flash and use fixit mode. i have root, var, tmp, usr and swap on my system. i create an extra swap partition to use it as journal provider for root partition. in fixit mode, first i run two below command in order to abel load gjournal: ln -s /dist/lib /lib ls -s /dist/boot/kernel /boot/modules then gjournal load and after that: gjournal label -f ad3s1a ad3s1g (ad3s1a is root partition and ad3s1g is swap partition for journal provider) but this error is shown: gjournal cannot clear metadata on ad3s1a: operation not permitted what is wrong here??? i really don't know how to fix it: On Thu, May 23, 2013 at 10:12 AM, Michael Sierchio ku...@tenebras.comwrote: On Wed, May 22, 2013 at 10:27 PM, s m sam.gh1...@gmail.com wrote: thanks Michael, but in all documentation about journaling, tunefs is used as below: tunefs -J enable ad3s1X.journal. ad3s1X.journal is created by gjournal command: gjournal label ad3s1a ad3s1g that assign ad3s1g as journal provider for ad3s1a and create ad3s1a.journal which contains ad3s1a as data provider and ad3s1g as journal provider. my problem is, i can not run gjournal command for root partition in fixit mode nor single user mode. you mean, i should just use tunefs command on ad3s1X (root partition)? if yes, then where journal provider for root partition is located? in root partition?
