kde-file manager su mode
by rado 29 Nov '05

29 Nov '05

hi y'all, ...realize that maybe I should go to kde w/this but then, I do run centos on my systems soooo... kk I like to run kde's file manager in super user mode. On one of my systems, it's acting it's ass...as my default editor I do use kwrite and I normally set that up to open any text type file w/that but for some reason, on this one certain system, I can't navigate among the folders. I double click on a folder as I normally do and it just throws me into kwrite instead on just navigating down the tree. Just wondering if any of y'all might have some ideas to correct this simply. I just can't seem to find the right config option to do it. thx John Rose -- ...and I woke up 2 days later in the back yard talking to Elvis!

Re: [CentOS] dags repo after 4.2 update

Yes. Then it went away, then it came back. dag repository is (again) nopped out of /etc/yum.conf. I know I'm a dummy, but this time, the problem may lie elsewhere.

USB Stick Install
by Bards1888 09 Nov '05

09 Nov '05

Hello all, I'm looking at setting up a sort of 'appliance' server and as such its really not going to have a lot packages etc. I thought of installing 4.2 on a 1gb USB stick, however, the stick is not even recongnized by anaconda. It did appear when I did 'modprobe usb-storage.ko' as /dev/sdc (i have already have 2 SATA disks which are sda, sdb). Then the disk partitioner does not allow me to install on the USB stick, its not even listed as an available drive. Does anyone have any redhat/centos experience with this ? I've successfully managed to get OpenBSD and Ubuntu to install and boot on exactly the same kit so there is nothing wrong hardware wise. I might try and disconnect the SATA drives before attempting the install to see if that make any difference. Thanks. Bards.

centosplus kernel
by Johnny Hughes 09 Nov '05

09 Nov '05

Just for the record, we are currently working with someone from SGI to get a much better implementation of XFS working with the centosplus kernel. I want to wait to push the centosplus unsupported kernel (2.6.9-22) until we have this new and much more stable version of XFS code implemented.

VPN via PPTP and MPPE
by James B. Byrne 09 Nov '05

09 Nov '05

I have set up a VPN over PPTP on a CentOS server using the DKMS module rpm dkms-0-2.0.6-3.el4 from http://centos.karan.org/el4/extras/stable/i386/RPMS/repodata/repovie w/dkms-0-2.0.6-3.el4.kb.html and kernel_ppp_mppe-0.0.5-2dkms.noarch.rpm at http://pptpclient.sourceforge.net/howto-fedora- core-3.phtml. I have configured the pptpd server on Centos4 to use MS_CHAPv2, 128bit encryption and to assign server side and client IP addresses in the range a.b.c.42-48 and a.b.c.52-58 respectively. I have also opened the firewall for tcp port 1723 and the GRE protocol (47). I have configured a Microsoft Win2Kpro client and I can connect and establish a VPN. However I am missing something because: 1. If I try and connect to a machine on the local network segment then the VPN channel is not used (this is probably the correct behaviour but it is not what I want and I need to know how to force local network paths over an encrypted connection). 2. If I try and connect to a host outside our local network then the traffic is not routed out through the gateway but it does travel over the vpn to the local pptdp server. So, what am I missing in all of this? Are there options for the pptpd that I need to set for this to work? I have a similar problem when I connect from outside the local network segment. The the vpn connects but then I cannot reach any other host. Any suggestions are welcome. I am a digest subscriber so if you could copy my email address on your reply then I would be appreciative.

firefox update extensions
by Dave 07 Nov '05

07 Nov '05

The update feature in FF appears to be disabled, which is fine since I upgrade from the repositories. But it looks like the extension updates are disabled as well. Even if I go to the extensions menu, right click on update they don't seem to update. Is there a setting to enable extension updates? I set extension.update.autoupdate to true in about:config and that didn't seem to help.

CentOS + GFS + EtherDrive
by Bowie Bailey 07 Nov '05

07 Nov '05

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup? Is GFS stable enough to use in a production environment? There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has anyone used this? Is it stable? Will I run into any problems if I use CentOS 3.5 with it's GFS package to access a shared 5TB filesystem? I've been googling on this stuff off and on for a month now. I've found a bunch of conflicting and confusing information, but no clear answers. I've been kind of hoping that the new GFS 6.1 packages would be released while I was waiting... :) I appreciate any suggestions or pointers. Bowie

Best mkfs.ext2 performance options on RAID5 in CentOS 4.2
by Sean Staats 02 Nov '05

02 Nov '05

I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance... System specs: ----------------- 2 x 2.8GHz Xeons 6GB RAM 1 3ware 9500S-12 2 x 6-drive, RAID 5 arrays with a stripe size of 256KB. Each array is 2.3TB after formatting. ioscheduler set to use the deadline scheduler. mkfs.ext2 options used: ------------------------ mkfs.ext2 -b 4096 -L /d01 -m 1 -O sparse_super,dir_index -R stride=64 -T largefile /dev/sda1 I'm using a stride size of 64 since the ext2 block size is 4KB and the array stripe size is 256KB (256/4 = 64). Output of using bonnie++: --------------------------- $ /usr/local/bonnie++/sbin/bonnie++ -d /d01/test -r 6144 -m anchor_ext2_4k_64s Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP anchor_ext2_4k_ 12G 41654 96 41937 11 30537 8 40676 88 233015 27 426.6 1 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 3369 83 +++++ +++ +++++ +++ 4142 100 +++++ +++ 11728 100 Cheers!
