nss_ldap: reconnected to LDAP server ldap://127.0.0.1
by Tim Alberts 18 Feb '11

18 Feb '11

Hello, I have a problem that I'm really having trouble figuring out. I run CentOS Linux 5.5. I have three servers. All have been setup and running with LDAP authentication for a couple years with absolutely no problems. Unfortunately a couple weeks ago, we had a power outage. Ever since, I am having continuous problems with authentication to the server. I see in /var/log/messages nss_ldap: reconnected to LDAP server ldap://127.0.0.1 I did run a yum update that installed an update to ldap, however that did not fix the issue. I have seen a post mentioning changing 'nss_connect_policy persist' to 'nss_connect_policy oneshot'. However I don't see this setting in my server, and again, the server was working perfectly fine for years before the power outage. I'm really thinking that some file got corrupted and I just need to clean it out. Maybe a cache file somewhere? Following is ldap.conf file. Any suggestions? <ldap.conf> base dc=inside,dc=msi timelimit 120 bind_timelimit 120 idle_timelimit 3600 nss_initgroups_ignoreusers root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman rootbinddn cn=Manager,dc=inside,dc=msi nss_base_passwd ou=People,dc=inside,dc=msi nss_base_shadow ou=People,dc=inside,dc=msi nss_base_group ou=Group,dc=inside,dc=msi uri ldap://127.0.0.1 ldap://my.domain ssl no tls_cacertdir /etc/openldap/cacerts pam_password md5 </ldap.conf>

Re: [CentOS] Any update on 5.6 / 6?

There are lots of people in similar circumstances to Larry. He has a recognised medical syndrome. People get problems. Some do not know how to effectively tackle their major problem so stress increases to a significant and detrimental extent. Often the person is never fully aware of high stress levels they have. Just because someone looks 'normal' it does not mean they are not in someway suffering. A good example is someone suffering from an incurable illness with a year to live. Can anyone really identity their significantly shorted lifespan just by looking at them in the street as they walk by? Diversions into irritating behaviour are a classic example of someone desperately trying to avoid thinking about, and therefore dealing with, a major problem. The reason they try to avoid thinking about the problem is the very high stress levels associated with that problem. It is too much for them to handle. The diversionary behaviour is a form of 'stress relief' and ultimately a cry for help. Larry is very likely curable. He just needs to talk confidentially and openly to someone who can begin to help him. Often a problem shared is a problem halved *and* the stress levels are lowered. Larry, I know you will read this, talk to a friend - Get help. With best regards, Paul. England, EU.

Software RAID Level 1, smartd and changing dev numbers
by James Smallacombe 18 Feb '11

18 Feb '11

We have about 50 CentOS servers with software RAID level 1 (mirroring). Each week, we swap out one of the drives (the one in the second of four hot-swap bays, only the first two of which contain drives) on each server and take them offsite for safekeeping. The problem is, the kernel seemingly randomly switches between /dev/sdb and /dev/sdc for these devices. This makes the process slower by requiring more manual input where a script(s) could otherwise suffice. It also confuses smartd, which AFAIK, needs the correct device names to report accurately. Ideally, we'd like to force the OS at some level to always see these devices as /dev/sda and /dev/sdb. If not, is there at least some way to configure smartd to be "smart" and recognize which devices are in use? TIA,

NIC bonding - missing eth0?
by Smithies, Russell 18 Feb '11

18 Feb '11

I have nic bonding (mode=802.3ad) setup on 2 servers, both running Centos 5.5 In the "Active Aggregator Info", on one reports 4 ports - which is correct - but the other only reports 3 ports. It's always eth0 that shows a different aggregator ID. Changing the cables around so it hits a different port on the switch makes no difference. The switch is correctly configured for the port channel. The only difference between the 2 servers is one is running Xen (kernel-xen-2.6.18-194.32.1.el5.centos.plus) so I have a few virtual interfaces and bridges. Any ideas what might be happening?

working with multiple password protected iSCSI targets on one host
by Rudi Ahlers 18 Feb '11

18 Feb '11

Hi, How do I setup multiple password protected iSCSI targets on Linux? I know that mounting a password protected iSCSI target requires modify these records with the appropriate values: node.session.auth.username = My_ISCSI_USR_NAME node.session.auth.password = MyPassword discovery.sendtargets.auth.username = My_ISCSI_USR_NAME discovery.sendtargets.auth.password = MyPassword But, now I need to mount another iSCSI target, from a different SAN that has a different username & password than whan I have configured here for the one already mounted. How do I tell iscsiadm which CHAP settings to use with which iSCSI target? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

write-back cache question
by James Chase 17 Feb '11

17 Feb '11

I have a perc5i (and perc5e) raid controller in my poweredge 2970 running centos 5.5. The RAID controller config is set for write-back policy, which I can confirm by checking in OpenManage. I also called Dell and ran their reporting application and had them double check to make sure everything looks OK hardware wise and they confirm that it does Yet when CentOS boots is appears to use the write through policy as can be seen below from dmesg output. Am I wrong that CentOS should query the RAID controller and go into the correct write mode: write-back? hub 1-5:1.0: 4 ports detected Vendor: DP Model: BACKPLANE Rev: 1.00 Type: Enclosure ANSI SCSI revision: 05 Vendor: DELL Model: PERC 5/i Rev: 1.03 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sda: 2435317760 512-byte hdwr sectors (1246883 MB) sda: Write Protect is off sda: Mode Sense: 1f 00 00 08 SCSI device sda: drive cache: write through SCSI device sda: 2435317760 512-byte hdwr sectors (1246883 MB) sda: Write Protect is off sda: Mode Sense: 1f 00 00 08 SCSI device sda: drive cache: write through sda: sda1 sda2 sda3 sd 0:2:0:0: Attached scsi disk sda megasas: 0x1028:0x0015:0x1028:0x1f01: bus 16:slot 14:func 0 GSI 21 sharing vector 0x62 and IRQ 21 ACPI: PCI Interrupt 0000:10:0e.0[A] -> GSI 18 (level, low) -> IRQ 98 megasas: FW now in Ready state

CentOS 5 on a Thinkpad T60 laptop
by Mathieu Baudier 17 Feb '11

17 Feb '11

Hello, I'm considering buying a second-hand Thinkpad T60 (with 2 GB RAM), as a secondary laptop in order to run CentOS 5 on the field. My main focus is therefore to have something robust, reliable and above all well compatible with CentOS. Hibernate / suspend feature are important to me, because that's the main issue I have with CentOS on other laptops. I have found the following information so far: http://www.thinkwiki.org/wiki/Installation_CentOS_5_on_a_Thinkpad_T60 The processor is a T2300 (so 32 bits apparently): http://ark.intel.com/Product.aspx?id=27233 I would be grateful if people having used CentOS on this model could share their experience (good or bad). Thanks in advance! Mathieu

foo2oak-wrapper

Well...Greetings A client bought for me a HP Color LaserJet 1525nw printer. Installed on the local network as 192.168.1.117 A Google search brings back a number of conflicting options. Before I ball things up to much, I thought it best to check in for additional advice. The CUPS installer is complaining that it cannot locate the foo2oak-wrapper...and that it should be installed before using the printer. Yum is like me, clueless. -- Hal Davison --Hal.
