Filesystem backup?
by Rafał Radecki 22 Jun '09

22 Jun '09

Hi all. I'm currently having a following problem: I have only ssh connection to a CentOS 5.2 system, there are two harddiscs on it. One stores the system (/ filesystem) and the other should be used to help restore the system in case of first disks' failure. I thought that maybe dump would be a good utility to make it. But in only works on read-only filesystems. In one article I've read that making a snapshot of the / filesystem (then it wouldbe read-only) and backing it could help. But aren't snapshots limited to logical volumes (LVM)? My friend told me to use rsync to back up the entire / filesystem to the second disk and then in case o failure the system from the copy should boot ok. Could anyone provide any suggestions? I don't have physical contact with the machine so for example RAID 1 isn't a possible option/ Any help will be very kindly appreciated. With regards, R.

Wifi connection finally solved
by Sorin Srbu 22 Jun '09

22 Jun '09

After a year or so of trying to get wifi-cards of various brands and chipsets to work, today it finally happened! I got my 3com 3CRPAG175 to jump to it and connect to the department WPA2 AP! I wouldn't have done it without your help. Thanks all! One question though, should it really take upwards of a minute or so till the NetworkManager says it's now connected?? -- BW, Sorin ----------------------------------------------------------- # Sorin Srbu [Sysadmin, Systems Engineer] # Dept of Medicinal Chemistry, Phone: +46 (0)18-4714482 >3 signals> GSM # Div of Org Pharm Chem, Mobile: +46 (0)701-718023 # Box 574, Uppsala University, Fax: +46 (0)18-4714482 # SE-751 23 Uppsala, Sweden Visit: BMC, Husargatan 3, D5:512b # Web: http://www.orgfarm.uu.se ----------------------------------------------------------- # () ASCII ribbon campaign - Against html E-mail # /\ # # MotD follows: # CentOS: Enterprise Linux for the rest of us.

gtk+-2 and centos 5
by Frank Cox 22 Jun '09

22 Jun '09

I'm a bit confused about how to compile somethingon Centos 5 that's looking for gtk +-2. ./configure errors out with this message: checking for GTK+ - version >= 2.4.0... no *** Could not run GTK+ test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means GTK+ is incorrectly installed. configure: error: Cannot find GTK2 The best information I could find on Google tells me this: "Edit the script file , it is looking for gtk+-2 while you have gtk2 installed." That's nice, but how? I edited the "configure" script and changed all references to read gtk2 and that did me no good at all. How can I address this issue? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com
