looking for good web based DNS script to check nameservers
by Rudi Ahlers 12 Oct '08

12 Oct '08

Hi all, I'm looking for a good web based script / website that can do a full ananlysis on DNS & namservers. Can someone please recommend something good to use? And if possible, if it could show any errors, or even make suggestions (like "TTL is too high", or " you don't have an MX, please ad one", etc) -- Kind Regards Rudi Ahlers

Hi All, I have a backup site and I would like to rsync from production to backup site. However, I would like to have all backups be compressed so I can save space. Can anyone recommend a good way to do this? I am currently using tar and bzip2 to do this. TIA

Any problems in the CentOS Samba?
by Spike Turner 11 Oct '08

11 Oct '08

Upstream bugzilla says :- Rebasing to Samba 3.0.32 would fix various current RHEL4 bugs. https://bugzilla.redhat.com/show_bug.cgi?id=460904 I have looked at the bugs.centos.org but did not find user reported bugs. Is anyone experiencing problems using the CentOS 4 samba? Spike.

Atheros AR5212/AR5213 wifi not working
by Marko Vojinovic 11 Oct '08

11 Oct '08

Hello everyone, I'm new to the CentOS list, so forgive me if this has been answered before (someone please point me to an efficient way of searching through the list archives). I have a wifi card from the subject line, and have the driver installed. Using NetworkManager under Gnome everything works perfectly. However, I prefer to use network service instead of NetworkManager since a) I use KDE and NetworkManager fails to work properly there b) this is a desktop machine, online 24/7 and I want wireless active even when I am not logged in. But when I use the network service, wifi0 fails after a delay, and /var/log/messages says there are no dhcp offers available. However, I am sure that there are several wireless networks available, with a strong signal. How to solve this? I would even accept using NM if it works as a daemon, ie even if I'm not logged in, and under KDE (which it doesn't atm). I believe the problem is essentially in the (in)ability to choose the appropriate network automatically --- in KDE NM doesn't have the taskbar applet which would let me choose the network, and the network service has no way of automatically making such a choice either... Please help! Btw, this is somewhat urgent, I am supposed to make it work by monday, Oct. 13. Oh, I almost forgot, CentOS 5.2, fully updated. Best, :-) Marko

NEW is new string. Hmm, why not ditch find entirely, and just use grep? Something like: TFIL=/usr/tmp/dummy$$.txt grep -Ilr "$STR" * > $TFIL for fil in $( cat $TFIL); do sed -i "s/$STR/$NEW/g" $fil done Man grep says: "-I Process a binary file as if it did not contain matching data". Also -l gives you the filename and relative path. If $STR contains "/"s then you could use # instead. sed -i "s#$STR#$NEW#g" $fil I dont know how much the searched for string would change, but you could test if it contained "/" and then use sed with "#" instead. Also you might want to use "sed -ibak ..." instead since this will backup the unchanged file to filename.bak, should your substitution go awry. The letters after "i" specify the extension you want to use. Eric Sisolak

Fwd: P5GC SATA mode problem
by Eduardo Grosclaude 10 Oct '08

10 Oct '08

Hello, I'm top-posting my own thread with some homework I've done, can somebody help? In short, the problem is that kernel 2.6.18-53 (as per 5.1 installation) works OK while any kernel update makes booting impossible in Enhanced SATA mode. For newer kernels, only Compatible mode works, but at a very heavy cost in performance. The motherboard is ASUS P5GC-MX and the disk is ATA WDC WD3200AAJS-6. More detail in my own former message at the end. 1. I have tried pci=nommconf, noacpi, acpi=off. Any other hints? 2. I've opened up both initrd files (initrd-2.6.18-53.el5.img, which works in "SATA/enhanced" mode, and the newer initrd-2.6.18-92.1.13.el5.img, which only works in "compatible") and found practically no differences (USB modules are loaded in a different order and that's about it). 3. In the hope that I could build up a working kernel (albeit sacrificing ease of update) I tried to figure out some useful config. I've scanned both config-XXX files but I am unable to identify any reasonable suspects either, diff provided below. Should SCSI-SAS-ATA be different? 4. Just to play a while, attempted to make mrproper and got the following. Same for make clean. [root@localhost 2.6.18-92.1.13.el5-i686]# make mrproper scripts/Makefile.clean:17: /usr/src/kernels/2.6.18-92.1.13.el5-i686/drivers/infiniband/hw/amso1100/Makefile: No such file or directory make[3]: *** No rule to make target `/usr/src/kernels/2.6.18-92.1.13.el5-i686/drivers/infiniband/hw/amso1100/Makefile'. Stop. make[2]: *** [drivers/infiniband/hw/amso1100] Error 2 make[1]: *** [drivers/infiniband] Error 2 make: *** [_clean_drivers] Error 2 So it seems 5.2's kernel really doesn't like me. Now, my questions: 1. What is going on? What can I read to understand a bit more? 2. As for the disk drive behaviour, should I file a bug? I haven't found any related known bugs. Does it depend on whether ASUS P5GC-MX is or not on the HW CL? 3. Is it on the HW CL anyway? I assume it is, from what I read at http://www.linux-tested.com/results/asus_p5gc-mx.html 4. As for the kernel compile error, what is going on again? Any hints deeply appreciated!

My 5.2 DVD refused to see the hard disk. As the CD happened to have a bad MD5 sum, I assumed this was due to a bad burnt image. Backed off to 5.1. Installation of 5.1 to /dev/sda went OK, then I upgraded by yum to 5.2. But, at the next boot, the new kernel can't see the disk. Only when BIOS IDE Setup is "compatible" I can boot the new kernel. However, the disk shows up as /dev/hdc and performance is noticeably slow. If I choose any other mode, nash complains that any LVM groups can't be found and panics away. I/O in general is terrible. Copying a CDROM to a file with dd renders the machine nearly unusable. The kernel provided in 5.1 can work in the BIOS IDE Setup "enhanced/SATA" and performance is really good. Hdparm when under the current kernel says 3.51 MB/s buffered speed, whereas for the older kernel it claims some 111+ MB/s. I have updated the BIOS ROM to no avail. What am I missing? Is there anything I can do except keep trying kernel updates?
