Memory recognition in 6.2
by Hugh E Cruickshank 20 Jun '12

20 Jun '12

Hi All: I have an HP DL380G5 server which I am loading CentOS 6.2 on and it does not appear to recognize all of the RAM installed on the server. The BIOS is reporting 26GB however top is reporting: Mem: 15720140k total, 418988k used, 15301152k free, 30256k buffers Swap: 17956856k total, 0k used, 17956856k free, 135536k cached and free is reporting: total used free shared buffers cached Mem: 15720140 418848 15301292 0 30256 135536 -/+ buffers/cache: 253056 15467084 Swap: 17956856 0 17956856 I have tried adding the mem= parameter to the /boot/grub/grub.conf file as in: title CentOS (2.6.32-220.17.1.el6.i686) root (hd0,0) kernel /vmlinuz-2.6.32-220.17.1.el6.i686 ro [SNIP] initrd /initramfs-2.6.32-220.17.1.el6.i686.img mem=26624M but this has not appeared to work. Any suggestions would be gratefully appreciated. TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com

PMA attacks
by m.roth＠5-cent.us 20 Jun '12

20 Jun '12

It appears to be a low-level attack, not so frequent as to be banned permanently, just a number of times a day. I did google on this, and I gather it's looking for phpmyadmin. We've been getting one from one specific network in Russia for weeks Here are more information about 91.201.64.24: [Querying whois.ripe.net] [whois.ripe.net] <snip> % Information related to '91.201.64.0 - 91.201.67.255' inetnum: 91.201.64.0 - 91.201.67.255 netname: Donekoserv descr: DonEkoService Ltd country: RU <snip> But now I'm seeing the same from Azerbaijan, and France, and elsewhere. Two questions: first, are other folks seeing this? and second, I can't imagine malware this stupid, to keep hitting the same sites over and over when it's not found, rather than bad password or user, so I'm wondering if this could be a targetting vector for an upcoming serious attack using another vector. Opinions? mark

Host system is Centos 6.2 on a Dell PE T610 with hardware raid on a PERC H700. Raid 5 is setup across three disks with a fourth hot spare. I have created a volume group within the raid 5 encompassing most of my drive space. Within the VG I have created numerous logical volumes that are assigned to specific systems. Volume Group: vg_mei Logical Volumes: lv_earthroot lv_earthswap lv_earthvar lv_sequoiaroot lv_sequoiaswap lv_sequoiavar lv_sequoiahome lv_sequoiaecosystem Earth is my host system and Sequoia is one of the guest systems. lv_sequoiaecosystem is the space dedicated to our Samba server and is the LV that I was expanding to make more space available to the rest of the staff. I had successfully extended lv_sequoiaecosystem using the following command from root on earth (lvextend -L+50G /dev/vg_mei/lv_sequoiaecosystem). Issuing the command (lvdisplay /dev/vg_mei/lv_sequoiaecosystem) following this showed that the LV was successfully extended from 100 to 150 GB. I then logged onto sequoia as root and issued a df -h to determine which device needed the file system to be resized (/dev/vde1). The output below is current, after I resized the filesystem using GParted. [root@sequoia ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/vda2 4.5G 2.5G 1.8G 59% / tmpfs 1004M 112K 1004M 1% /dev/shm /dev/vda1 485M 55M 406M 12% /boot /dev/vde1 148G 85G 56G 61% /ecosystem /dev/vdd1 20G 1.3G 18G 7% /home /dev/vdc1 2.0G 266M 1.7G 14% /var Then from root on sequoia I issued the command (resize2fs -p /dev/vde1) and got back the result that the filesystem is already 26214144 blocks long, nothing to do. That is when I posted my first question about not being able to resize a live mounted filesystem. Is that enough information for your question, or is there something that I am not providing? Thanks. Jeff
