Re: [CentOS] Help With Installation to USB Stick
by Mark Rose 15 Dec '06

15 Dec '06

I went ahead and verified the labels on my partitions, and /dev/sda2 is labelled "/" and /dev/sda1 has a label of "/boot". Like I previously mentioned, I believe /boot is fine since grub loads - I am still at a loss as to why it can not see /. I installed the pendrive into my home PC running 4.4 and /dev/sda2 looks fine. I also ran fsck on it and it is clean. A while back, it was suggested that I run mkinitrd and include the USB drivers. I tried this, but it still wasn't recognized. If anyone can help me get pointed in the right direction, it will be greatly appreciated. Thanks!

Desktop link to URL with port number fails in CentOS 4.4
by Edward Diener 15 Dec '06

15 Dec '06

If I create a desktop item which is a link to a URL with a port number, opening the desktop item fails. I can create the desktop item by dragging and dropping the URL from my web browser, firefox. The desktop item, when I attempt to open it, brings up a message box with the title "Cancel Open?", a lightbulb icon, a message "Opening 'myURL:myPort'. You can stop this operation by clicking cancel.", and a single Cancel button. If I type directly into a terminal "firefox http://myURL:myPort/", firefox will correctly open that web page ( firefox is my preferred web browser ). So this is not a firefox problem but a Gnome desktop link problem evidently. Other URLs without a port number open correctly from a desktop link. Is there a way to fix this ? It probably has something to do with interpreting the URL as a Mime type for Gnome, but I do not know how I can correct the behavior so that URLs with port numbers are correctly passed to my preferred web browser, firefox.

Hi: I have a mirror of dag repository (http://apt.sw.be/redhat/el4/en/i386/dag/) in my intranet which is used by other servers to install/update rpms. I installed on every remote server the rpmforge rpm, edit the /etc/yum.repos.d/rpmforge.repo to fit with my intranet mirror, but when I run yum, I get this error: #yum -c rpmforge.repo search nagios Warning, could not load sqlite, falling back to pickle Repository rpmforge is listed more than once in the configuration Searching Packages: Setting up repositories //var/cache/yum/rpmforge/repomd.xml:1: parser error : Document is empty ^ //var/cache/yum/rpmforge/repomd.xml:1: parser error : Start tag expected, '<' not found ^ rpmforge 0 B 00:00 ftp://repository.cimex.com.cu/dag/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for rpmforge: Error: could not parse file //var/cache/yum/rpmforge/repomd.xml Trying other mirror.

Getting kernel source for 2.6.9-42.ELsmp
by Charles E Campbell Jr 14 Dec '06

14 Dec '06

Hello! I need to get an arcnet device driver up and running. Normally it appears to be distributed with linux, but not installed. So, I need to compile and install it, naturally. So, where is the kernel souce for 2.6.9-42.ELsmp? I can find kernel source for 2.6.9. BTW, I obtained 2.6.9 and tried compiling it, but all I got was *.o files and insmod: error inserting 'arcnet.o`: -1 Invalid module format Seems that the rest of the /lib/modules/2.6.9-42.ELsmp/kernel/drivers/net appear to be *.ko files. Hope y'all can help! Charles Campbell

New VLC (0.8.6) packages?
by chrism＠imntv.com 14 Dec '06

14 Dec '06

Anyone know where I could find this package for Centos 4.4 x86_64? I've googled all over and haven't been able to find anything more current the 0.8.4a. I'm not much of a programmer, but if someone could point me at a "packaging for dummies" perhaps I could have a go at creating a package if one doesn't already exist? Cheers,

Re: [CentOS] Help With Installation to USB Stick

Hi: Thanks for the advice. I think I did try this (actually, I believe when I went through the CentOS install (graphical if it makes any difference) by default it labelled it as /. I am hoping tonight or tomorrow to try to do another install and will give it a shot!

/var/log/secure timestamp
by Andres Baravalle 14 Dec '06

14 Dec '06

Hi everyone, I have some very strange information in my /var/log/secure: find /var/log | xargs grep -i 62.149.129.73 2>/dev/null /var/log/secure:Dec 13 21:32:38 baravalle xinetd[1219]: START: smtp pid=26049 from=62.149.129.73 /var/log/secure:Dec 13 21:32:38 baravalle sshd[26048]: Did not receive identification string from ::ffff:62.149.129.73 /var/log/secure:Dec 13 20:33:33 baravalle sshd[26059]: Failed none for invalid user admin1000000 from ::ffff:62.149.129.73 port 3754 ssh2 /var/log/secure:Dec 13 21:33:42 baravalle sshd[26058]: Failed password for invalid user admin1000000 from ::ffff:62.149.129.73 port 3754 ssh2 /var/log/secure:Dec 13 20:33:42 baravalle sshd[26059]: Failed password for invalid user admin1000000 from ::ffff:62.149.129.73 port 3754 ssh2 Apparently someone tried to log in with a user name (I changed the username here). I don't like the timestamps: 21:32:38, 20:33:33, 21:33:42, 20:33:42. Why is that? By the way, most probably the access has been done by my provider. They are denying it, but there is overwhelming evidence: the username used is the one that they gave me, which is the word admin and a string of 7 digits. The username should be known just by me, my business partner and my provider. The username was anyway invalid in the system, because I had disabled SSH access from all users but the ones in a group. Nevertheless, in their records, the provider had another user name that I didn't disable (stupid me) because they did some maintenance work not long ago. I can't see any access from the correct user name since the last time I had authorised them to access the server. Anyone able to bring some light? Andres
