CentOS5 and samba
by lhecking＠users.sourceforge.net 19 Apr '10

19 Apr '10

We're trying to migrate RHEL3 and CentOS4 based samba servers over to CentOS5, but it's a bleeding disaster. We cannot get it to work reliably with any version of CentOS5, i386 or x86_64, the included 3.0.x version of samba or 3.4.x/3.5.x compiled from source. The symptoms are: read access is extremely slow, write access seems to work in principle (e.g. creating a zeros-sized file on a share), but writing even small files (100k) to the share eventually times out with "out of memory or disk space" errors. These shares are home directories NFS-mounted on the samba server. Shares of local disks work fine as expected. We have played with oplock settings and got some improvements, but not reliably, and this seems to effect XP and Seven clients differently. Surely we are not the first to run into this sort of issue? Given the range of tested software, the problem appears to be specific to CentOS5. --------------------------------------------------------------- This message and any attachments may contain Cypress (or its subsidiaries) confidential information.

Problem with first login
by sync 19 Apr '10

19 Apr '10

Hi , guys: I have a problem on the openldap Manager account login : The server is running CentOS 5.3 i386 and I have phpldapadmin-1.0.1-1.el5.noarch.rpm installed . It's running apache 2.2.3 with php 5.1.6 and openldap 2.3.34. I believe I have slapd setup correctly but I'm not completely sure. My /etc/openldap/slapd.conf file has... access to * by self write by * read by anonymous auth database bdb suffix "dc=my-domain,dc=com" rootdn "cn=Manager,dc=my-domain,dc=com" rootpw {SSHA}xxxxx My /etc/ldap.conf has the following lines (among others)... host 127.0.0.1 base dc=my-domain,dc=com If I do the following command... ldapsearch -x -D "cn=Manager,dc=my-domain,dc=com" -W from the command line it asks for a password. If I type the password I created with slapppassd and have as rootpw in slapd.conf it carries on and returns the following (with comments removed)... search: 2 result: 32 No such object So it appears that from the command line authentication with ldap is working. In my phpldapadmin config.php file i've modified the following lines... $ldapservers->SetValue($i,'server','host','127.0.0.1'); $ldapservers->SetValue($i,'server','port','389'); $ldapservers->SetValue($i,'server','auth_type','session'); When I go to phpldapadmin and do "Anonymous Bind" it connects and allows me to view the ldap tree. If I try and login with user "Manager" and the password I use on the command line, it doesn't work giving me... "Bad username or password. Please try again." I've also tried putting the following line to my config.php file but to no avail... $ldapservers->SetValue($i,'server','base',array('my-domain', 'com')); Am I using the correct username? Are there any commands I can do to further check my ldap server is setup correctly? Are there any log files I can look at? Thanks for all your help.

(semi-) rugged laptop running CentOS 5?
by Jim Davis 19 Apr '10

19 Apr '10

We're looking for a laptop to run in a 10,000', cold, occasionally wet environment, and it needs to run CentOS 5. Perhaps something like the Dell Latitude E6400 ATG? There's a reference to a minor trackball bug for the 6400 under CentOS 5 (http://bugs.centos.org/view.php?id=4192) but otherwise it sounds like the x86_64 version should run on it. Ideally the system would use a SSD too. Any suggestions?

by Jagan Kommineni 19 Apr '10

19 Apr '10

Dear All, I have installed CentOS release 5.2 (Final). EMC SAN partition is mounted by using EMC Powerpath for resolving multiple paths. I was able write and read data over to SAN partition without any issues. Subsequently I have unmounted EMC SAN partition from the system and deleted LUN using Navisphere user interface. After rebooting system, I still see SAN mappings in system. Here is the affected partition mappings .... ============================== cat /proc/partitions ============================== major minor #blocks name 8 16 1048576 sdb 8 48 1048576 sdd 8 80 1048576 sdf 8 112 1048576 sdh ============================ When I try to print information using parted, I am getting the following information .... ========================================================================================= #parted /dev/sdb GNU Parted 1.8.1 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Error: Unable to open /dev/sdb - unrecognised disk label. (parted) ============================================= I would like to get rid of partition mappings from the system.

CentOS installation on x86 platform
by hadi motamedi 19 Apr '10

19 Apr '10

Dear All I had two x86 platform that I needed to install CentOS 5 on them. On one of them that had Windows OS pre-installed, I installed VBox and then I installed CentOS inside its VBox. On the second platform, I tried for a fresh installation of CentOS as its primary OS (I mean inserting the CentOS installation CD and rebooting the machine and following the instructions to install the CentOS). On the second platform, I want to install Windows OS again and as I don't find proper VM machine for my CentOS so I tried to put the Windows installation CD and reboot the machine but it was unsuccessful. Actually it didn't read the Windows installtion CD and just boots up from its CentOS . As I chose to 'remove all partitions on this machine' when installing the CentOS so I think I need to change its FAT to be able to re-install Windows OS. Can you please comment me back what was wrong on my second machine that I cannot re-install Windows OS on it? Thank you

CentOS-friendly wiki engine ?
by Niki Kovacs 18 Apr '10

18 Apr '10

Hi, One of our local town halls has asked me to implement a wiki-based website dedicated to ecological farming. The wiki is supposed to host a variety of documents in text, video and audio format. I've never used any wiki engines myself. Is there any one you can recommend in particular ? I'm using CentOS 5 on the server, so I would be glad to use a solution where I don't have to jump through burning loops (e. g. install a more recent version of PHP/Python/whatever) to make it work. Cheers, Niki

ext3/ext4 random write performance on ioDrive duo
by Ryousei Takano 17 Apr '10

17 Apr '10

Hi all, I have evaluated Fusion-io ioDrive duo (PCIe direct attached NAND flash memory storage) on the CentOS 5.4. The experimental result shows the write performance with multiple jobs (processes) on the ext3/ext4 filesystems is lower than that of XFS. The question I have is what is the cause of the ext3/ext4 performance limitation. I have measured the random write performance on several filesystems using fio benchmark (http://freshmeat.net/projects/fio/) My PC box has dual Intel Xeon W5590 3.33 GHz (8 cores), 48 GB memory, and Fusion-io ioDriveDuo (320 GB SLC). The XFS performance grows as the number of jobs increases. On the other hands, the ext3/ext4 do not. In the both cases, I mount filesystems with the "noatime" option only. The results are shown below: block size XFS XFS ext4 ext4 (1job) (8job) (1job) (8job) 1024 21 71 22 21 2048 40 144 42 40 4096 74 290 76 76 8192 131 635 133 131 16384 212 1029 219 215 32768 310 1169 326 316 65536 399 1236 374 374 131072 748 1332 718 676 262144 895 1336 902 804 524288 1000 1327 974 905 1048576 1100 1308 1136 995 2097152 1220 1276 1179 1082 4194304 1230 1233 1270 1149 8388608 1309 1233 1243 1188 (The unit is MB/s.) You can see the more detail information from here: http://code.google.com/p/pspacer/wiki/ioDriveDuo Any comments and suggestion will be welcome. If this list is not proper place to talk about this problem, can anyone tell me the proper one? Best regards, Ryousei
