is it possible to login to a switch via RS232 / serial port from the shell?
by Rudi Ahlers 23 Jun '08

23 Jun '08

Hi all I have a problem switch in our data centre, which is connected to a linux server via a serial cable. I know I can / could access the switch from my Windows PC back at the office, using hyperterm, but trying to access it using minicom just doesn't seem to work. I have changed the comms in minincom to use /dev/tty0 & the baud rate to 9600, yet I can't seem to connect with minicom. Does anyone know how to connect to a serial device from the console? -- Kind Regards Rudi Ahlers CEO, SoftDux Office: 087 805-9573 Fax No: 086 609 6128 Cell: 082 554 7532 Web: http://www.SoftDux.com Forum: http://Forum.SoftDux.com Join SA WebHostingTalk today, on http://www.WebHostingTalk.co.za

I got a chance to reboot the server this weekend and happy to report that my iscsi/multipath/lvm volumes are discovered and automatically mounting on boot. It worked!

Migrating from RHEL to Centos
by Hemraj S 23 Jun '08

23 Jun '08

Hi, I m currently running my production servers on RHEL 4.6 & would like to migrate to Centos4.6 as it has more benefits & advantages. I looked at the Centos release notes available at http://mirror.centos.org/centos/4.6/os/i386/RELEASE-NOTES-en.html and understood that the basic difference between RHEL & Centos are look/feel related & binaries,functionalities are almost same. But when i compared the sysctl values of RHEL4.6 with Centos4.6, i found that there are lot of differences in the parameter values. Now my question is: 1) Just like sysctl difference, is there any other difference between RHEL & Centos which could vary the performance & needs to be taken care during migration. 2) When the Centos packages are built, are they built with the same configuration as in RHEL or is there any difference. Thanks & Regards, Hemraj

cannot unmount volume "xxx"
by 李晖 23 Jun '08

23 Jun '08

Hi all: I am using Centos 5.1. But now I have a problem when unmount a removable usb hard disk with right click and choose unmount volume command. When I did that, system reminds me with a message like this:Cannot unmount volume "xxx", Detail: Cannot remove directory, "xxx" represents a temporary directory made when the system auto mount the disk in /media, and "xxx" is simple-chinese. But in fact, the volume has been removed because there're no files or folder in xxx. Because the file system type of the hard disk is NTFS, Ｉ install ntfs-3g and add a script named "mount.ntfs" in /sbin, the content of the script is #!/bin/sh export LANG=zh_CN.UTF-8 exec /sbin/mount.ntfs-3g "$@" I googled this problem for many days and didn't find any way to solve this problem. Maybe it is a bug. I hope someone can help me. Thank you. -- Sunny Lee

Rsync + crontab centos5.1
by Frank Murphy 22 Jun '08

22 Jun '08

Just looking at the "man rsync". Might as well be duagnosing a plattypus. I have made a dir on my Cent samba shares to setup a local fedora.repo (1) How do I get it to run weekly at a certain time. is this correct? crontab -e 22 7 0 0 /usr/bin/rsync -va /Fedora-Mirror /local samba share. (2) Trying to get cron it run 10pm every saturday night. Log whats happening. update packages, include new packages. Exlude extra languages from things like openoffice\xorg etc.. that the family don't need. (family lan) (3) Would one normally download the mirrors "repodata", or run create createrepo oneself?
