VMWare Sandbox
by Thom Paine 05 Nov '08

05 Nov '08

I need to experiment with ldap for a site I manage, and wondered if vmware would be a good way to go for some testing. My current server is RHEL3, which is getting dated, and I think that I should refresh this server entirely in the move to ldap. We need to have an ldap server for publishing email addresses for a VPN for a nursing home that the upstream can harvest and we can browse to send confidential patient records. RHEL3 prollie won't cut it, so I'm considering moving to CentOS5. If I get a nice working test environment working, I wondered about running the server on VMWare, because the hardware will likely need to be refreshed in 2 years anyways. Copying the vmware file and the data to a new server would make for a fast upgrade. Any feedback on what I am attempting to do here? Any other recommendations on how I should tackle this? Currently I'm using Samba 3 with passdb. It's nothing fancy, but it works. We have about 20 XP machines here. The server also hosts mail as well. -- -=/>Thom

I intend to backup both Windows and Linux server. Can I use this to backup my linux mail server with Zimbra services shutdown? Can I use this to backup windows server machine without using Samba or it is the only way to go. I intend to read manual of these two when I got my machine to test, for a while maybe I can get some insight from those who have already experience using these tools.

Hi After upgrading a machine from RHEL-4.5 to 5.2, the Gnome doesn't start anymore. There are strange messages when I issue the command "startx" (I'm using inittab=3). The message is nautilus: symbol lookup error: /usr/local/lib/libgtk-x11-2.0.so.0: undefined symbol: pango_language_get_default Where is the information to "nautilus" look in /usr/local/bin? Thanks Marcelo

SATA errors on CentOS 5.2
by MHR 05 Nov '08

05 Nov '08

We have a new machine here that we are trying to use for CentOS as a base for our primary application. Although I do not have direct access to the physical machine, I have begun looking into it remotely (via ssh) to see why we are getting the following errors periodically: /var/log/messages.1-Nov 1 18:19:00 Centos5 kernel: hda: status timeout: status=0xd0 { Busy } /var/log/messages.1:Nov 1 18:19:00 Centos5 kernel: ide: failed opcode was: unknown /var/log/messages.1-Nov 1 18:19:00 Centos5 kernel: hda: no DRQ after issuing MULTWRITE_EXT /var/log/messages.1-Nov 1 18:19:00 Centos5 kernel: ide0: reset: success This happened 12 times (at least) in the last four days, and it (reportedly) does not occur if FC9 is booted on that machine. The machine is configured as follows: Pentium Core 2 Duo at 3.4GHz, 1GB RAM Intel m/b, not sure exactly which one, but here's what lspci shows: 00:00.0 Host bridge: Intel Corporation 82Q963/Q965 Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02) 00:1a.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #5 (rev 02) 00:1a.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 5 (rev 02) 00:1c.5 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 6 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev f2) 00:1f.0 ISA bridge: Intel Corporation 82801HO (ICH8DO) LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA IDE Controller (rev 02) 00:1f.5 IDE interface: Intel Corporation 82801H (ICH8 Family) 2 port SATA IDE Controller (rev 02) 02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller 03:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller 04:0c.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) 04:0d.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) 04:0e.0 Communication controller: Comtrol Corporation RocketPort 16 port w/external I/F (rev 04) 04:0f.0 Non-VGA unclassified device: PLX Technology, Inc.

I've run the smartctl utility, and it shows no errors. What am I missing? Is it odd to have two SATA controllers for a single disk drive, or is that at all relevant? Thanks. mhr

nfs and permissions
by Anne Wilson 05 Nov '08

05 Nov '08

My CentOS box is my server for data and some services, including nfs shares. On my laptop I have folderviews displaying two directories on the server, via nfs mounts. An fstab line mounts each, such as: 192.168.0.40:/home /mnt/borg2_home nfs nosuid,exec,rw,bg,soft,intr 0 0 From the folderview I have no problem accessing the files and directories. Now comes the problem. I use kontact, with imap mail (working fine) and a calendar/diary (korganizer) mounted as a remote file. At least, I did, until this new install. I can give it the path, but I don't see any entries. I suspect that it is a permissions problem, but I can't see anything obvious. The firewall is temporarily disabled. Any ideas. please? Anne

How to get Bugzilla working on CentOS 5.2 with SELinux turned on?
by Aleksey Tsalolikhin 05 Nov '08

05 Nov '08

Hi. Has anyone figured out how to get Bugzilla working on CentOS 5.2 WITHOUT TURNING OFF SELINUX? I've run chcon -R --reference=/var/www/html /path/to/bugzilla and added the following module (generated by audit2allow), but am still getting errors in my Web browser tryinig to use Bugzilla: Software error: Can't connect to the database. Error: could not connect to server: Permission denied Is the server running on host "localhost" and accepting TCP/IP connections on port 5432? Is your database installed and up and running? Do you have the correct username and password selected in localconfig? And there is an AVC denial as well: type=AVC msg=audit(1225832104.970:405): avc: denied { connect } for pid=30831 comm="index.cgi" scontext=user_u:system_r:httpd_sys_script_t:s0 tcontext=user_u:system_r:httpd_sys_script_t:s0 tclass=tcp_socket Here is the module I added: module local 1.0; require { type httpd_sys_script_t; class tcp_socket setopt; } #============= httpd_sys_script_t ============== allow httpd_sys_script_t self:tcp_socket setopt; [root@hwd-ddc-app-prod01 selinux]# httpd_sys_script_t ============== allow httpd_sys_script_t self:tcp_socket setopt; I've tried running the AVC denial message through audit2allow again, but it just produced the same module that I already have loaded. Any suggestions? Thanks, Aleksey -- Aleksey Tsalolikhin UNIX System Administrator "I get stuff done!" http://www.lifesurvives.com/
