Basic setup for vsftpd ?
by Niki Kovacs 08 Jun '09

08 Jun '09

Hi, I'm currently fiddling with G4U (Ghost for Unix), and I need to setup a local FTP server in order to get it to work. # yum groupinstall "FTP Server" --> installed vsftpd Here's what I'd like to do : * no anonymous access * only one user (user 'install' / pass 'install') The machine I'm installing it on has a static IP ok (192.168.1.252/255.255.255.0). I tried to fiddle with the various configuration options in vsftpd.conf, but to no avail. Googled quite some, but the information I found doesn't seem reliable, more like contradictory. One detail: this isn't a publicly accessible machine, e. g. it's not out there on the wild internet, only on the LAN, so there's no special security considerations. Any suggestions ? Niki Kovacs

Re: [CentOS] libwpd/libwpd-devel deps screwed?

Oh, sorry, fixed it with rpm -iv --force libwpd-0.8.7-3.el5.i386.rpm rpm -iv --nodeps libwpd-devel-0.8.7-3.el5.i386.rpm I suppose the RPM database is too fragile by design.

please help: Linux Kernel must be loaded before initrd
by Rudi Ahlers 08 Jun '09

08 Jun '09

Hi, One of my servers in a IDC in another country mysteriously went down this morning, and when I contacted the IDC, I was told that XEN doesn't boot up, as follows: [QUOTE] This is error message on the screen " Error 19: Linux Kernel must be loaded before initrd" Server is currently up with 2nd kernel. Please check the grub.conf. [/QUOTE] Looking at grub.conf, I see the following: #boot=/dev/hda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-128.1.10.el5xen) root (hd0,0) kernel /xen.gz-2.6.18-128.1.10.el5 ro root=/dev/VolGroup00/LogVol01 ide0=noprobe ide1=noprobe initrd /initrd-2.6.18-128.1.10.el5.img title CentOS (2.6.18-128.1.10.el5) root (hd0,0) kernel /vmlinuz-2.6.18-128.1.10.el5 ro root=/dev/VolGroup00/LogVol01 ide0=noprobe ide1=noprobe initrd /initrd-2.6.18-128.1.10.el5.img title CentOS (2.6.18-128.el5) root (hd0,0) kernel /vmlinuz-2.6.18-128.el5 ro root=/dev/VolGroup00/LogVol01 ide0=noprobe ide1=noprobe initrd /initrd-2.6.18-128.el5.img Then on another server, I see the following in grub.conf: #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-8.1.15.el5xen) root (hd0,0) kernel /xen.gz-2.6.18-8.1.15.el5 module /vmlinuz-2.6.18-8.1.15.el5xen ro root=/dev/VolGroup00/root module /initrd-2.6.18-8.1.15.el5xen.img title CentOS (2.6.18-8.1.15.el5) root (hd0,0) kernel /vmlinuz-2.6.18-8.1.15.el5 ro root=/dev/VolGroup00/root initrd /initrd-2.6.18-8.1.15.el5.img title CentOS (2.6.18-8.el5) root (hd0,0) kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/root initrd /initrd-2.6.18-8.el5.img On both kernels, I can see that initrd is loaded 2nd, as it should. So the error doesn't make sense. The BIG problem is that the server is on another continent, and their support is totally useless. I have actiall ordered a new server, from another IDC and got it last night, but need XEN to work on this server in order to move the domU's across. Can anyone see anyting wrong with this? Google has revelaed the obvious, that the initrd is incorrectly loaded, but according to the grub.conf that I have, it should be loading properly. -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Random server reboot after update to CentOS 5.3
by Peter Hopfgartner 08 Jun '09

08 Jun '09

Dear ML We upgraded a Dell Poweredge PE 1950 Server the 8th of May. Since then the server rebooted 3 times without external cause (it is located in a server farm with redundant power supply etc.). Looking at the servers monitoring infrastructure with Dell's own OpenManage tools, I get strange errors: [root@servernew ~]# omreport system esmlog (....) Severity : Critical Date and Time : Mon May 11 17:46:59 2009 Description : System Software event: run-time critical stop was asserted Severity : Critical Date and Time : Fri May 15 21:07:57 2009 Description : System Software event: run-time critical stop was asserted Severity : Critical Date and Time : Wed May 20 21:00:53 2009 Description : System Software event: run-time critical stop was asserted (...) This class of errors never happened before in over a year that the server is running. There is no mention of any anomaly, except the boot messages itself, in /var/log/messages. The server runs the 64 bit flavor of CentOS hosting some XEN virtual machines and some PostgreSQL and MySQL databases. It run without any issues with CentOS 5.1 and 5.2. I interpreted these issues as some kernel/software related problem, but do not know how to make a more accurate diagnosis of the problem. Can anybody give me some hint? Has anybody had some similar issue? Regards, Peter -- Dott.

Let me absolutely clear on this, when I say 'production' I'm speaking about my personal home network only. This network consists of a very few machines with very limited access to the outside world. I use it for my education and experience only. So production, to me, is a environment I don't want to update more than once a year. Thanks, Gene Poole

Question about dd (fill a hard disks' unused space with blanks)
by Niki Kovacs 08 Jun '09

08 Jun '09

Hi, I'm currently experimenting with G4U (Ghost for Unix), a small cloning application sending disk images to an FTP server. The application reads the whole disk bit by bit, compresses it and then stores it remotely. Due to this approach, it's more or less filesystem-independent. The drawback is that it sometimes results in huge image files. Now I'm currently following a hint which suggests to fill the disks' unused space with zero bits. Here's the command for that: # dd if=/dev/zero of=/0bits bs=20M # rm /0bits Now I gave that a shot, but after half an hour or so, I got a bit impatient. Now the computer does not respond any more. Does that mean he's just way too busy with dd? Or is there some mistake in the command? As I see it, it will just be chugging on and on, no? Shouldn't there be a 'count=x' option somewhere? Niki

script help - '3rd last field'
by Tom Brown 08 Jun '09

08 Jun '09

Hi I need some logic to work out a value for me - this value is _always_ the 3rd last field in a string seperated by '.' but the string could be 5 or 6 fields long, e.g foo.bar.VALUE.baz.lala foor.bar.gigi.VALUE.baz.lala I need to find VALUE - if this were python or something i could do it but this has to be in shell - Any clues? thanks
