Problems with latest 5.3 yum update and grub
by Scott Ehrlich 21 May '09

21 May '09

I recently updated two 64-bit CentOS 5.3 systems via yum update. - One system had two physical SATA hard drives - drive 0 was Windows XP w/SP3 w/NTFS, drive 1 was CentOS; - The other system had two physical SATA hard drives, configured via a hardware mirror of RAID 1 (mirroring) After the latest yum update, grub on both systems failed me, dropping to the grub prompt. For the dual-boot system, I ended up reformatting and reinstalling Windows on drive 0. The CentOS was not touched. That system is fine now. For the RAID CentOS-only system, I experimented with removing one drive from the mirror and CentOS booted as though it was reboot after a fresh install, though there were some traces that something else (like an upgrade) was mixed in, but didn't work right. I ended up deleting the hardware RAID and removed a drive. That system works fine now. Has anyone else experienced grub problems with more than one drive installed from a recent yum update? I will not perform an update on any other multi-drive systems, including servers, until I know things are fixed. Thanks for any insights. Scott

CentOS5 Desktops authenticating to 389 Directory Server
by Clint Dilks 21 May '09

21 May '09

Hi Everyone. I am doing some LDAP testing. I have setup a 389 Directory Server on CentOS 5 and using the default schema I have populated it with a couple of users. I then did the configuration on the client that I thought was needed to make it authenticate. To test this I expected to be able to use id <uidNumber> of a user I had defined. But I get id: 1001: No such user id: 5001: No such user I then thought perhaps it was an LDAP permissions problem so I tried binding to the LDAP server using a user I know has full rights using these entries in /etc/openldap/ldap.conf there was no change. BINDDN cn=admin,dc=scms,dc=waikato,dc=ac,dc=nz BINDPW LDAPt3st I can query these users from a desktop that I want to use the LDAP server as an authentication source. Using * ldapsearch -x -H ldap://distilled.scms.waikato.ac.nz -b dc=scms,dc=waikato,dc=ac,dc=nz uid=LDilks* # extended LDIF # # LDAPv3 # base <dc=scms,dc=waikato,dc=ac,dc=nz> with scope subtree # filter: uid=LDilks # requesting: ALL # # LDilks, People, scms.waikato.ac.nz dn: uid=LDilks,ou=People, dc=scms, dc=waikato, dc=ac, dc=nz givenName: LDAP-Clint sn: Dilks telephoneNumber: 4546 loginShell: /bin/bash gidNumber: 1001 uidNumber: 1001 mail: clintd(a)scms.waikato.ac.nz objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetorgperson objectClass: posixAccount uid: LDilks gecos: A Test LDAP account cn: LDAP-Clint Dilks homeDirectory: /home/LDAP-clint # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 *[root@distilled2 ~]# ldapsearch -x -H ldap://distilled.scms.waikato.ac.nz -b dc=scms,dc=waikato,dc=ac,dc=nz uid=BBuilder* # extended LDIF # # LDAPv3 # base <dc=scms,dc=waikato,dc=ac,dc=nz> with scope subtree # filter: uid=BBuilder # requesting: ALL # # BBuilder, scms.waikato.ac.nz dn: uid=BBuilder,dc=scms, dc=waikato, dc=ac, dc=nz givenName: Bob sn: Builder loginShell: /bin/bash uidNumber: 5001 gidNumber: 5001 objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetorgperson objectClass: posixAccount uid: BBuilder gecos: Got to love Cartoons cn: Bob Builder homeDirectory: /home/bob # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 The three files config files I am aware of are cat /etc/openldap/ldap.conf # # LDAP Defaults # # See ldap.conf(5) for details # This file should be world readable but not world writable. #BASE dc=example, dc=com #URI ldap://ldap.example.com ldap://ldap-master.example.com:666 #SIZELIMIT 12 #TIMELIMIT 15 #DEREF never URI ldap://distilled.scms.waikato.ac.nz BASE dc=scms.dc=waikato,dc=ac,dc=nz #BINDDN cn=admin,dc=scms,dc=waikato,dc=ac,dc=nz #BINDPW LDAPt3st TLS_CACERTDIR /etc/openldap/cacerts cat /etc/nsswitch.conf | grep -v '^#' | grep -v '^$' passwd: files ldap shadow: files ldap group: files ldap hosts: files dns bootparams: nisplus [NOTFOUND=return] files ethers: files netmasks: files networks: files protocols: files rpc: files services: files netgroup: files ldap publickey: nisplus automount: files ldap aliases: files nisplus cat /etc/pam.d/system-auth #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth sufficient pam_ldap.so use_first_pass auth required pam_deny.so account required pam_unix.so broken_shadow account sufficient pam_succeed_if.so uid < 500 quiet account [default=bad success=ok user_unknown=ignore] pam_ldap.so account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password sufficient pam_ldap.so use_authtok password required pam_deny.so session optional pam_keyinit.so revoke session required pam_limits.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so session optional pam_ldap.so Can anyone give me any pointers as to where I am going wrong ??

magic.mime dependency problem between file and httpd

Hi everyone! :-) While doing a regular manual yum update on my ContOS 5.3 server, yum complained as follows: [root@sith ~]# yum update Loaded plugins: fastestmirror, priorities Loading mirror speeds from cached hostfile * epel: ftp.icm.edu.pl * rpmforge: ftp-stud.fht-esslingen.de * base: centosb2.centos.org * updates: centose.centos.org * extras: centosb2.centos.org * addons: mirror.nsc.liu.se 2152 packages excluded due to repository priority protections Setting up Update Process Resolving Dependencies --> Running transaction check ---> Package file.i386 0:4.17-15.el5_3.1 set to be updated --> Processing Dependency: /usr/share/magic.mime for package: httpd --> Finished Dependency Resolution httpd-2.2.3-22.el5.centos.i386 from installed has depsolving problems --> Missing Dependency: /usr/share/magic.mime is needed by package httpd-2.2.3-22.el5.centos.i386 (installed) Error: Missing Dependency: /usr/share/magic.mime is needed by package httpd-2.2.3-22.el5.centos.i386 (installed) So what is wrong and why?

[OT] Oracle->MySQL ODBC via SSL using: stock MySQL, mysql-connect or-odbc-3.51.27-0, Oracle XE
by Jason Pyeron 21 May '09

21 May '09

I know this is very off topic, but getting MySQL and unix ODBC to play nice via SSL on Centos has been a battle. I finally have it working via isql but when I connect via Oracle I get an error. If I use the mysql odbc connector directly: ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [Generic Connectivity Using ODBC][MySQL][ODBC 3.51 Driver]SSL connection error (SQL State: S1000; SQL Code: 2026) ORA-02063: preceding 2 lines from USGNWEB If I connect via unixODBC: ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [Generic Connectivity Using ODBC][unixODBC][MySQL][ODBC 3.51 Driver]SSL connection error (SQL State: S1000; SQL Code: 2026) ORA-02063: preceding 2 lines from USGNWEB My assumption is that I am missing some environment variable in Oracle's environment, but what should I look for? What information could I provide that would be helpful? -Jason -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00.

MySql Query Cache
by James Matthews 21 May '09

21 May '09

Hi, One of the servers I run is a VPS running Lighttpd fcgi which I am running a simple wordpress blog off of. Since RAM is the biggest limitation I have disabled the query cache on MySql. Now I have the following questions. 1. What does the FCGI server cache now? 2. How can I speed up this setup? 3. Will turning on the query cache speed things up? I am trying to make sure the system doesn't swap much so things stay snappy. Thanks James -- http://www.jewelerslounge.com

Couldn't recognize the image file format for file /usr/share/gdm/themes/Default/background.png error
by Dale - Ehome 21 May '09

21 May '09

Hello All, I am getting the following error on re-booting my CentOS 4.5 server: "There was an error loading the theme *Default*" "Couldn't recognize the image file format for file '/*usr*/*share*/*gdm*/*themes*/*Default*/*background*.*png*'" It appears that when I click on the OK dialog the server continues to boot, with no update to the screen. I have in the past verified that this file exists and does not appear to have any problems. I can now get remote access to the server and wish to do whatever it takes to prevent this from happening in the future. This summer I hope to upgrade the box to the latest CentOS. I do know the box will need to be restarted once before that time due to some planned changes at the co-loc. Any ideas on what to change/fix to prevent this from happening again? Thank you very much! Dale

help with rebuilding md0 (Raid5)
by Daniel Bird 21 May '09

21 May '09

Sorry, this is going to be a rather long post...Here's the situation; I have 4 IDE disks from an old snap server which fails to mount the raid array. We believe there is a controller error on the SNAP so we've put them in another box running CentOS 5 and can see the disks OK. hda thru hdd looks like this Disk /dev/hdd: 185.2 GB, 185283624960 bytes 255 heads, 63 sectors/track, 22526 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdd1 * 1 2 16041+ 83 Linux /dev/hdd2 3 70 546210 83 Linux /dev/hdd3 71 138 546210 5 Extended /dev/hdd4 139 21781 173844468 83 Linux /dev/hdd5 71 104 273104+ 83 Linux /dev/hdd6 105 138 273104+ 83 Linux I can mount hdX1 and hdX2 (hdx2 is xfs) on all disks.

Or do I need to reset the superblocks and re-assemble in degraded mode somehow? TIA Dan

Squid proxy as a Gateway Server
by Ashish Gangani 21 May '09

21 May '09

Hi all, Good Day for all, I need Help to Setup Squid proxy as a Gateway Server. The Idea is to use the (Server and Gateway) configured with Squid to run using AUTH_Pam or AUTH_ncsa , but additionally we need to filter some access via group, following the standard filter group used Filter Group 1 - blocked users (no access) Filter Group 2 - standard users (standard access rights) Filter Group 3 - guest users (limited access rights) Filter Group 4 - power users (more generous access & file download rights) Filter Group 5 - admin users (unlimited access) So in this cases all users are authenticated by the Server Only when their try to access internet, they received access denied if user is has no access based on group membership. Thanks and Regards, Ashish Gangani,
