by Fidel Dominguez-Valero 06 Apr '11

06 Apr '11

Friends I have a good ftp server working with authentication of users, but I want to put a folder with general information for everyone can read without having to log in, that is to be seen both registered users and guests too. -- Fidel Dominguez-Valero Linux User: 433411 Website: http://www.valerofix.ryanhost.net

File-system Corruption
by James Bensley 06 Apr '11

06 Apr '11

Hi List, I suppose this isn't strictly CentOS but I'm talking about some 5.5 servers so I thought someone else here may have had the same issues; We power on servers at night via IPMI and shut them down the same way for automation. The problem I'm facing is that the servers are shutdown in about 2 seconds. IPMI provides remote access to the power features as we know so I don't think the OS has a chance to do a 'graceful' shutdown. One server in particular is told to shutdown at say 07:00am, the last scheduled task on there should finish around 06:30 so there is a half hour window for over run. It now has a corrupt XFS file system which I am repairing as we speak. I am wondering if this could be a possible cause of these problems? Perhaps if that last tasks over runs a couple of times and it gets powered off in the middle of the tasks? (These are backup servers rsyncing from other servers) Does anyone here have problems with this? -- James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...?

CentOS 5.6 will not install due to Firefox error
by Gilbert Sebenste 06 Apr '11

06 Apr '11

Hello all, Well, my local mirror now has CentOS 5.6! Yay! But, I cannot get it to install. A "yum update" and a "yum --skip-broken" yields me this: --> Processing Conflict: firefox conflicts xulrunner >= 1.9.2.14 --> Finished Dependency Resolution firefox-3.6.13-2.el5.centos.i386 from installed has depsolving problems --> firefox conflicts with xulrunner Skip-broken could not solve problems Error: firefox conflicts with xulrunner You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest The program package-cleanup is found in the yum-utils package. Any ideas? All the packages seem to be there. ******************************************************************************* Gilbert Sebenste ******** (My opinions only!) ****** *******************************************************************************

ZFS @ centOS
by Dawid Horacio Golebiewski 06 Apr '11

06 Apr '11

I have trouble finding definitive information about this. I am considering the use of SME 7.5.1 (centOS based) for my server needs, but I do want to use ZFS and I thus far I have only found information about the ZFS-Fuse implementation and unclear hints that there is another way. Phoronix reported that http://kqinfotech.com/ would release some form of ZFS for the kernel but I have found nothing. Can so. tell me if fuse-ZFS is more trouble than it's worth? Thanks in adv.

Understanding yum automatic upgrades
by email builder 06 Apr '11

06 Apr '11

Hello, Sorry if this is somewhat naive, but I'm a little confused as to what the criteria is for that which will get upgraded automatically by yum and what will not. I see in our logwatch messages from time to time that yum upgraded a bunch of stuff, but I also notice that yum will not upgrade other packages at all (easy example is clamav, but there are others). Can someone explain or point me to where I can read about the distinction between what is and is not subjected to automatic upgrade? Thanks!

Some clients also thread by subject by default, I usually use claws mail for ML stuff as it's threading is excellent. Says the guy sending this email in Outhouse.... Josh

OFFTOPIC :: IB hardware choice
by Adrian Sevcenco 06 Apr '11

06 Apr '11

Hi! I would need an advice from those that use IB (as admins :) ) i have a choice between : 1. Mellanox InfiniHost® III Lx HCA card, single-port CX4, DDR, PCIe x8, mem-free, tall bracket, RoHS R5 2. QLogic Single Port 20 Gb InfiniBand to x16 PCI Express Adapter (Single Pack) aside the price is there anything else that could help me make a discrimination between this two? (these will be used in twin servers for a small (up to 24 nodes) parallel cluster) Thanks! Adrian

Re: [CentOS] KILL THIS THREAD ( Centos 6 Update?)

----- Original Message ----- > From:Kai Schaetzl <maillists(a)conactive.com> > > > This thread or others like it will continue > > wrong. It will continue as long people bite. Stop biting the bait! > > Kai Oh, the irony.... Likewise. Somebody will still keep coming onto ask the questions, esp. non-regular list users.... hell, people do it now and the subject has been done to death over the last few months. I personally see little point in the threads either. As far as I can tell, you have to accept the situation as-is or switch distro. Dev model isn't going to change and previously said, anyway... maybe the rebuild model for non-hobbyist use has run its course.

sshd: Authentication Failures: 137 Time(s)
by Rainer Traut 06 Apr '11

06 Apr '11

Hi, to prevent scripted dictionary attacks to sshd I applied those iptables rules: -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -m recent --update --seconds 60 --hitcount 4 --name SSH --rsource -j DROP -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -m recent --set --name SSH --rsource And this is part of logwatch: sshd: Authentication Failures: unknown (www.telkom.co.ke) 137 Time(s) unknown (mkongwe.jambo.co.ke): 130 Time(s) unknown (212.49.70.24): 107 Time(s) root (195.191.250.101): 8 Time(s) How is it possible for an attacker to try to logon more then 4 times? Can the attacker do this with only one TCP/IP connection without establishing a new one? Or have the scripts been adapted to this? Thx Rainer
