Re: Kerberized CIFS client?
Derek Taylor wrote: This question was previously posed of the freebsd-questions list, but with no response for a week, I'd like to try my luck here. If there's any more information I should include, please speak up: I would be glad to oblige. I would like to use smb/cifs with kerberos auth, but mount_smbfs doesn't seem to support this. Is anyone aware of an alternate means of performing a mount via smb/cifs or any patches to provide such functionality? I already have smbclient working with -k, but I am also interested in a mount. Try smbnetfs from ports. It's fuse based and seems to work very nice. If you have a large amount of shares floating in your network you want to restrict it to mount only the needed shares via the config file. Otherwise it will mount what it can find... It plays nicely with kerberors. When your ticket expires you immediately loose access; when you renew it you gain access again. All without the need to unmount/mount. Just call smbnetfs once you have your ticket. You may even do this from your .profile. harti ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Maximum memory allocation per process
Hi Guys I have a problem with a perl script running out of memory. From my googling I have found that perl itself does not seem to impose any memory limits, and I have check ulimit and login.conf for any userclass limitations but found nothing that seems to be limiting my memory. I have 128MBytes of RAM and a 2Gbyte swap partition. I am currently running FreeBSD albert 6.2-STABLE FreeBSD 6.2-STABLE #11: Sun Sep 2 00:45:05 EST 2007 which I guess isn't exactly the latest... but the same thing happens on my REL7.0 Box The process (imapsync in this case) runs out of ram at pretty much 512MB. I read on a forum that BSD 6 imposes such a limit of 512MB per process, but i have found no where to tune this, or even see what it is. I have also read that there are two sysctl namely, kern.maxdsiz and kern.maxssiz, that can tune memory allocation but what happend to them in Freebsd 6.

You need to modify some kernel settings via /boot/loader.conf and reboot. Here's what we use on our production RELENG_6 and RELENG_7 boxes: # Increase maximum allocatable memory on a process to 2GB. # (We don't choose 3GB (our max RAM) since that would # exhaust all memory, and result in a kernel panic.) # Set default memory size as 768MB. # Maximum stack size is 256MB. # kern.maxdsiz="2048M" kern.dfldsiz="768M" kern.maxssiz="256MB" > I have also read that there are two sysctl namely, kern.maxdsiz and > kern.maxssiz, that can tune memory allocation but what happend to them in > Freebsd 6. These are not sysctls, they are kernel settings. They exist on both RELENG_6 and RELENG_7. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

ATA patch for RELENG_6
I got this patch a while ago and I don't see it appearing in RELENG_6
yet. Can someone "sheperd" this along or point out why it's not acceptable?
This patch was generated by a failure to boot correctly off of a compact
flash IDE module from Transcend.

You can also use the newer getaddrinfo(3)/freeaddrinfo(3). I think it is bit easier to use and can it transparently handle inet6 addresses as well. The only downside is that some rare old systems don't support it. On FreeBSD it is suppoorted since FreeBSD-4, but some commerical OS implemented it later. -- B.Walter <[EMAIL PROTECTED]> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You should use getaddrinfo() instead, which is more flexible and easier to use, and it enables you to easily write code that is independent and agnostic of the address family (IPv4 vs. IPv6 vs. others).
