by David Suhendrik 25 May '10

25 May '10

Hello All, I had problems with the security server, the server is frequently attacked using bruteforce attacks. Is there an application that can perform automatic blocking when there are failed login to the ports smtp, pop3 port, and others? I am currently using CentOS 5.5 in some servers Thanks in advanced....... -- -- Best regards, David http://blog.pnyet.web.id

Naming of a Java Process in Linux
by Jatin Davey 25 May '10

25 May '10

Hi Not a specific question on CentOS but in general about java processes running on Linux boxes. I have a couple of java processes running on my linux boxes , They basically form a component of a bigger application. My point of interest is to monitor the resource usage of the java processes running on the linux box. So currently when i have these procs running on my box they show up as "java" in the ps -A command. I dont know for sure as to which java process belongs to which component of my appliacation. Hence what i do is add up all the resource utilization values for all java processes as my monitoring application relies on process names. So what i thought was , Is there a solution in linux or the way the JVM is initiated can we have process names different for different java processes. To be more specific if i have two java processes running in my system , in order to identify them properly can i have it running as java_1 or java_2 or something in those lines. Please let me know if its possible. Thanks Jatin

can't update CENTOS - mirrore issue? or what?
by Dave Stevens 24 May '10

24 May '10

For about a week a biug stack of updates have been pending for CENTOS but I can't install them. The yum update command leads to dependency resolution in the usual way but it always ends in this: ---> Package poppler-utils.i386 0:0.5.4-4.4.el5_4.11 set to be updated ---> Package xorg-x11-drv-qxl.i386 0:0.0.12-1.2.el5 set to be updated --> Running transaction check --> Processing Dependency: gmime = 2.2.10-5.el5.centos for package: gmime-sharp ---> Package java-1.6.0-openjdk.i386 1:1.6.0.0-1.7.b09.el5 set to be updated http://linux.mirrors.es.net/fedora-epel/5/i386/repodata/0a2db1a48154104f63a…: [Errno 14] HTTP Error 404: Not Found Trying other mirror. http://www.muug.mb.ca/pub/epel/5/i386/repodata/0a2db1a48154104f63a810226536…: [Errno 14] HTTP Error 404: Not Found Trying other mirror. [...and about another thirty lines with some intended-to-be-helpful suggestions that don't work.] At first I thought it might just be that the mirrors were busy with lotsa downloads but as time goes by this is a progressively less and less satisfactory situation. Does anyone else have this problem? or a suggestion? TIA, Dave -- "It is no measure of health to be well adjusted to a profoundly sick society." Krishnamurti

apache redirection
by Ski Dawg 24 May '10

24 May '10

Hello everyone, Part of our website has secured access with an SSL certificate. The problem we are running into is that the certificate is for www.domainname.com, so when they go to domainname.com (without the www. in front), the users are getting a "This connection is untrusted" warning, because the url doesn't match the certificate. I found one site that said to make a change to the apache conf file, which I have done. The change that I made is adding: <VirtualHost xxx.xxx.xxx.xxx:80> ServerName domainname.com Redirect permanent / http://www.domainname.com/ </VirtualHost> This works great to redirect the users to http://www.domainname.com when they go to http://domainname.com. The problem I am running into is if they go to https://domainname.com (straight to the secure site), I am not able to find a solution that will redirect them to https://www.domainname.com, so that the ssl certificate matches and they won't get the "This connection is untrusted" warning. I tried using the same thing as above, but changing the port number to 443, and the http to https on the redirect line, but that actually breaks the site, and only displays an error: Secure Connection Failed (Error code: ssl_error_rx_record_too_long) Is there something obvious that I am missing? Is there a better way to ensure that everyone will always end up with the www in the url, so the certificate always matches? Any thoughts and suggestions would be greatly appreciated. -- Doug Registered Linux User #285548 (http://counter.li.org) ---------------------------------------- Never trust a computer you can't throw out a window. -- Steve Wozniak

Mounting LVM disk
by Weiner, Michael 24 May '10

24 May '10

List Readers - I have a Dell server that uses the Perc 6i controller and had 5 1Tb disks installed (1 for OS and the other 4 in a Raid0 for a large storage pool). The owner of the server wanted me to swap out the 1Tb disks for 2Tb disks - easy enough I thought, but I ran into some issues trying to clone the OS disk to the new 2Tb disk, so I just did a re-install. So basically we now have 5 2Tb disks (1 for OS and the other 4 in a Raid0) like before. I was able to copy off the data that was on the original Raid0 volume and put it back on the newly created one that is now 8Tb and that worked well enough. But since I was unable to clone the original OS disk, and proceeded to simply re-install the OS, the owner apparently wants his $HOME directory copied off (which of course resides on the 1Tb OS disk). So, being a SAS disk, I purchased an ICY Dock which allows me to mount the SAS disk in an external enclosure, and plug it in via USB (SAS -> SATA -> USB). However when I do a 'fdisk -l /dev/sdc' I receive the following: [root@gc-server2 ~]# fdisk -l /dev/sdc Disk /dev/sdc: 2199.0 GB, 2199023255552 bytes 255 heads, 63 sectors/track, 267349 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdc doesn't contain a valid partition table Two things are a bit unusual here, first of all its not a 2Tb disk, and secondly why cant I read the partition table. Originally the OS was on an LVM volume and by default it was setup as /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 My question is, is there a way to connect and mount this via USB and be able to get the $HOME directory stuff off that I failed to copy off before removing the disk?

Building an install disk on a USB key, solved
by m.roth＠5-cent.us 24 May '10

24 May '10

Ok, there's been discussion, including, I think, on the wiki web page, that syslinux is not correct. At any rate, after enough experimentation, I have a working install on a USB key. The procedure is: Using fdisk, partition your key: one partition, VFAT (type b, and toggle the bootable flag), about 9M or 10M, and a second partition big enough to hold a DVD. That should be type 83 (Linux native). mkfs -t vfat <the DOS partition) mkfs <the Linux partition liveCD-iso-to-disk <.iso, w/ full path> /dev/<USB DOS partition> mount <USB Linux partition> /mnt cp <CentOS.iso> /mnt/ You're done. You do have to tell it "install from hard disk", and then point it to the Linux partition. I just did this and tested it (or at least as far as the "searching for existing CentOS installations). mark
