Anyone still uses "MO drive"?
by Fajar Priyanto 27 Mar '08

27 Mar '08

Hi all, I'm trying to use an old MO drive in Centos5.0. It's connected to an adaptec scsi card. From dmesg, the card seems to be recognized, but it doesn't "create" the sda device from the MO drive. Is there any more steps I must do? From Yahoo search (since it has older archive than google), it seems that Linux should be automatically recognize and setting up the scsi card and the MO drive. So, I'm clueless here. Any pointer is great. Thanks. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 09:37:09 up 2:02, 2.6.22-14-generic GNU/Linux Let's use OpenOffice. http://www.openoffice.org The real challenge of teaching is getting your students motivated to learn.

Widescreen monitor with Intel G965 graphics chipset

I just migrated my working Fedora Core 8 desktop to CentOS 5.1 and went from my nice 1680x1050 resolution to 1280x1024. I have made all the possible xorg.conf changes I found on the net to no avail. I tried system-config-display –reconfig and it allows me to pick the resolution but reverts back to 1280x1024 in X? Anyone know what might need to be done in CentOS for this to work? The skewed aspect ratio drives me nuts☺ Thanks! jlc

Two Internet connections...
by Frank Cox 26 Mar '08

26 Mar '08

I do some occasional tech work for a cable TV/Internet service provider. They have now offered me free services, including cable Internet. I currently have a DSL service through the telephone company and, for several reasons including the fact that it is really unlimited service with no cap and it comes with newsgroup access (neither of which the cable service has), I'm not really prepared to give that up. However, since I can get a free cable Internet service too I would like to be able to put that to use. Does anyone have any good ideas for what to do with an extra cable Internet service? Is there, say, a way to somehow "shotgun" two Internet services like you used to be able to do with dial-up modems to increase your transmission speed? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

After rebooting servers 3 or 4 times that way myself, I now disable this function in /etc/inittab on all of my servers. I don't see any point in allowing a hot-key to reboot a server. -- Bowie

Monitor connections?

Hi, I just setup a dedicated server on OVH, and I wonder: what's the best way to monitor connection attempts? Like: folks trying to connect on various ports? Cheers, Niki

System Rebooted by 2.6.18-8.1.8.el5
by Andrew Hearn 26 Mar '08

Hello, I have a machine that seemed to reboot by itself yesterday, in /var/log/messages I only see: Mar 25 14:26:45 asterisk shutdown[19256]: shutting down for system reboot When I type: last reboot I see: reboot system boot 2.6.18-8.1.8.el5 Tue Mar 25 14:28 (18:41) So it seems like the kernel rebooted, but I'm not sure how I can track down why, any pointers? Thanks! Andrew

We have CENTOS version 3,4 and 5 on DELL servers. What I want to know is how to setup SFTP log file similiar to vsftpd.log. I knew /var/log/secure provide me login user information, but I need more detail like "file name", "get/put", etc. Thanks you for help. 付費才容量無上限？Yahoo!奇摩電子信箱2.0免費給你，信件永遠不必刪！ - 馬上體驗！

It just makes them > fail. That's the point about moving port etc., not the security. Agreed. I have one machine on my network that exposes an ssh connection on a non-standard port. My logs for the last month do not show a single failed connection attempt. -- Bowie
