Interface bonding?
by Timothy Selivanow 23 May '08

23 May '08

I'm try to bond a few interfaces together with the hopes of getting increased throughput, and I'm using a cisco Catalyst 2900 as the switch. I've tried using mode 0, 5, and 6 with nothing special on the switch, and mode 4 with some ports "trunked" together (I have a feeling that the "trunking" that the 2900 does is not 802.3ad, as it disabled the ports it saw as redundant), yet xfer speeds always cap out at about 10MB/s. Has any body accomplished bonding with increased throughput as the goal, with or without (without might be preferable) doing something special on the switch (preferably the afore-mentioned Catalyst 2900, as that is what I have to work with as a non-sactioned side-project ;)? --Tim ___________________________________________________ < When pleasure remains, does it remain a pleasure? > --------------------------------------------------- \ \ \ \ /\ ( ) .( o ).

Re:Re:Can't get past the splash screen
by Eon Strife 22 May '08

Hi, Thanks, it's Gnome, and I'm stuck when I login as root. By using Putty, I managed to create a new user, and then I tried to login to desktop(using nomachine) as that user, and yes, it works. The problem now is that I stuck when I login as the root. Then, I compared the runlog (the one I wrote in that previous email), between the root's and the new user's and, they're the same. Then, I compared the sshlog, and I found discrepancies. In the sshlog of the root, there are some additional lines saying unable to open a file and unable to start the sesion: === NX> 285 Identified internal connection NX> 285 Using default mode encrypted NX> 285 Identified options: nx/nx,options=/cygdrive/C/Users/EONSTR~1/NX73F8~1/S-8728~1.ORG/options:1000 NX> 280 Proxy opened with local: 7 remote: 8 NX> 285 Switching descriptors: 4 and: 5 to: 7 NX> 287 Redirected I/O to channel descriptors NX> 280 Proxy in: 4 out: 5 transport in: 8 out: 8 NX> 596 Session startup failed. <- The additional line in the sshlog of the root NX> 1004 Error: NX Agent exited with exit status 1.

User pressed Ok. === I checked the permission of that var/lib/nxserver/ (and folders (including /db/running/ ) and files inside it), the permission is 0700 (read,write,execute enabled for the owner), with the group is root and owner is the nx. And yes, also using the root I can view the content of the var/lib/nxserver. If I login using that new user, I can't view the content. Oh,yeah, pressing start and leaving for few hours don't solve the problem. Checking the .bash_history file, these are the commands I issued around the time when I messed up : === useradd aaa useradd --help useradd abc passwd aaa useradd --help useradd -d /home/aaaa/ -p aaaaaa aaa which useradd /etc/rc.d/init.d/autofs stop /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs stop /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs stop /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs stop etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs stop userdel --help userdel aaa passwd aaa /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs stop cd /home/ ls rmdir --help cd aaa ls del --help delfile --help cd \. cd /. cd /home/ rm -r /home/aaa/ ls /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs reload /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs start /etc/rc.d/init.d/autofs stop /etc/rc.d/init.d/autofs start ls /etc/rc.d/init.d/autofs stop exit ypcat ypcat group group grouplist groupls groups users uname uname -s -n -m -r id whoami w root w ps ps ps -f ps -a === Thanks. === I am not in front of a machine with the nxclient on it, I will be in the morning and can see what some of the logs look like there; however, the ling concerning automatic reconnect to true makes me think the device is attempting to start up a session that doesn't exist. I can't prove that, but I will have more information tomorrow. Concerning your screen shot, I've only ever been stuck at that screen once and simply hitting enter at the keyboard made it vanish. The splash screen should time out anyhow once the start up stuff times out if gnome/kde/xfce's initialization routine takes too long. What desktop (window manager?) are you using? Is it Gnome, KDE or something else? I've not seen selinux create an issue, but for posterity is it running? Does it log anything on the system you're attempting to connect with? Oh, what about permissions for the user? Does the user have the ability to write to his/her home directory properly? You could be getting stuck on the splash screen because the user can't write any data for the initialization.

Current Chipset Compatibility
by John Paulson 22 May '08

22 May '08

Can someone make a recommedation as far as best chipset for Centos 5.0 or 5..1 using a Q6600 series CPU with chipsets that have onboard VGA? From poking around it looks like the G33 and P35 are not supported or have problems until the newer 2.6.22 kernel (the iso's appear to be earlier than that, think it was .18)? So I am considering boards with the Intel G965 chipset but not sure if is supported yet? Can someone make a recommedation as far as best chipset for this scenario? thx -- John

AW: [CentOS] question on minimal install using CF as /dev/sda
by Marc Rebischke 22 May '08

22 May '08

Hi all, We're attempting to use CentOS 5.1 on a test platform which uses a CF card as it's primary storage. (MB: ETX-LX) The BIOS supports booting from CD and/or the CF. Issues we've run into are: During installation of CentOS 5.1, it appears all goes well through partitioning, package selection, interface configuration. Once the install starts in earnest, errors pop up...a snippet is: ================ Traceback (most recent call first): File "/usr/lib/python2.4/site-packages/yum/packageSack.py", line 640, in returnNewestByName raise PackageSackError, 'No Package Matching %s' % name File "/usr/lib/python2.4/site-packages/yum/packageSack.py", line 318, in returnNewestByName return bestofeach.returnNewestByName(name) File "/tmp/treedir.29352/instimage/usr/lib/anaconda/yuminstall.py", line 1093, in getBestKernalByArch pkgs= ayum.pkgSack.returnNewestByName(pkgname) File "/tmp/treedir.29352/instimage/usr/lib/anaconda/yuminstall.py", line 1102, in selectBestKernel kpkg = getBestKernalByArch("kernel", self.ayum) File "/tmp/treedir.29352/instimage/usr/lib/anaconda/yuminstall.py", line 1236 in doPostSelection self.selectBestKernel(anaconda) File "/tmp/treedir.29352/instimage/usr/lib/anaconda/backend.py", line 177 in doPostSelection return anaconda.backend.doPostSelection(anaconda) ================== It appears that we're not writing to the CF and a driver is needed. We have the driver, but are uncertain how to pass the information to the installer. No Floppy is present. Any thoughts or suggestions or pointers to resources would be greatly appreciated. Regards, -Ray _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ########################## Ray, Which Driver do you mean ? Since CF-Cards are IDE/ATA-Compatible there's normally no need to install any Drivers to Access the CF. If you really need a driver for a Hardware-Component during install you could copy the driver to an USB-Stick instead a floppy... Some more Ideas/Hints... You could/should check if the md5/sha-checksum of the downloaded CentOS ISO(s) is/are OK. Did you made any changes to the "minimal Installation" Package-List ? If you are using the netinstall.iso you could give the "full" CD/DVD-ISO(s) a try. Just my 2 Cents for now. Regards Marc Rebischke

RE: [CentOS] COBOL

CentOS may work well > for development and testing platform, but the production code should > be on fully supported RHEL. Having been on RHEL support, and having had occasion to use that support quite extensively, I have formed an opinion to the contrary. My experience did not lead me to the conclusion that licensed RHEL distributions, together with the highest available level of support offered by RedHat, provided any measurable benefit over CentOS and community support. In fact, my experiences with RedHat Support, which were not in the least bit negative, led me to abandon RedHat, first to WhiteBox and thence to CentOS. The practical matter is that RedHat Support is provided in layers, with minimally experienced person filtering support calls. This was, and I expect still is, the case regardless of what level of support is purchased. By the time a serious problem got to a person in RedHat who possessed anywhere near my own experience with the systems under consideration either I had already solved the issue (usually with help from Goole or project specific mailing lists), identified a satisfactory workaround, or had determined that the problem was unsolvable in the timeframe required with the resources available. RedHat support people were unfailingly polite and helpful, but the fact remains that the value for fee was not evident. Immediate support (which is really the only kind that matters to an organization, anything else is really a development project of some sort) for open source systems comes in two basic flavors, enlightenment and custom consulations. Enlightenment is provided by informed individuals who are willing to share their knowledge and experience with others who problems are products of their own ignorance. Members of this mailing list have provided enlightenment to me on many, many occasions. Custom work is either provided from ones own resources or is contracted out to people who really know the system you need fixed/enhanced within a minimal amount of time. I have engaged open source software authors to enhance their products with features that our firm desired on many occasions and in fact am doing so with one at the present time. I cannot perceive any measurable advantage to having a support contract for OSS, other than perhaps with the actual core team of the exact product you are using. RH is a packager, which is not to denigrate either the value of the integration work that they do, or its technical merit. Nonetheless, most OSS support problems are either resolved by re-reading the specific package documentation, having an obscure feature identified and explained by someone that knows about it, bypassing the impediment, or when all else fails writing and submitting your own patch. -- *** E-Mail is NOT a SECURE channel *** James B.

Strange NTP problem
by Alfred von Campe 22 May '08

22 May '08

I have 30 identical Lenovo desktop systems running CentOS 5.1. On one of those systems the clock is running slow (5+ minutes from yesterday to this morning and another minute since this morning) despite the fact that NTP is running on all of them and they all have the exact same /etc/ntp.conf file (I compared the MD5 sums of that file on all the systems). Here is the output of "grep ntp /var/log messages" on the system with the problem since I restarted the NTP daemon earlier today: May 20 11:35:38 hepdsw03 ntpd[31791]: ntpd 4.2.2p1(a)1.1570-o Sat Nov 10 12:33:50 UTC 2007 (1) May 20 11:35:38 hepdsw03 ntpd[31792]: precision = 1.000 usec May 20 11:35:38 hepdsw03 ntpd[31792]: Listening on interface wildcard, 0.0.0.0#123 Disabled May 20 11:35:38 hepdsw03 ntpd[31792]: Listening on interface wildcard, ::#123 Disabled May 20 11:35:38 hepdsw03 ntpd[31792]: Listening on interface lo, :: 1#123 Enabled May 20 11:35:38 hepdsw03 ntpd[31792]: Listening on interface eth0, fe80::210:c6ff:feab:dd92#123 Enabled May 20 11:35:38 hepdsw03 ntpd[31792]: Listening on interface lo, 127.0.0.1#123 Enabled May 20 11:35:38 hepdsw03 ntpd[31792]: Listening on interface eth0, 10.66.42.109#123 Enabled May 20 11:35:38 hepdsw03 ntpd[31792]: kernel time sync status 0040 May 20 11:35:38 hepdsw03 ntpd[31792]: frequency initialized 0.000 PPM from /var/lib/ntp/drift May 20 11:38:55 hepdsw03 ntpd[31792]: synchronized to LOCAL(0), stratum 10 May 20 11:38:55 hepdsw03 ntpd[31792]: kernel time sync disabled 0001 May 20 11:39:59 hepdsw03 ntpd[31792]: synchronized to 10.101.32.104, stratum 3 May 20 11:40:58 hepdsw03 ntpd[31792]: synchronized to LOCAL(0), stratum 10 May 20 11:42:09 hepdsw03 ntpd[31792]: synchronized to 10.101.32.104, stratum 3 May 20 11:47:26 hepdsw03 ntpd[31792]: synchronized to LOCAL(0), stratum 10 May 20 11:49:31 hepdsw03 ntpd[31792]: synchronized to 10.101.32.104, stratum 3 May 20 11:52:48 hepdsw03 ntpd[31792]: synchronized to LOCAL(0), stratum 10 May 20 11:54:54 hepdsw03 ntpd[31792]: synchronized to 10.101.32.104, stratum 3 May 20 12:01:26 hepdsw03 ntpd[31792]: synchronized to LOCAL(0), stratum 10 Any idea what could be causing this? For now I have disabled the NTP daemon and am running ntpdate once an hour. What complicates the matter is that we are using Kerberos for authentication, and after a day or so the user can not log into his system anymore because of the time skew. Alfred
