recovering data off failing/failed hard drive
by Chris O'Halloran 17 Jul '07

17 Jul '07

Hello people, As the linux fan at work I was offered an old machine to set up a wiki at work. I migrated much of the data off a private wiki I kept on my home machine and set up the wiki using Kubutu Server 6.06 LTS. The wiki is phpwiki and uses mysql as the backend. The machine stopped serving webpages yesterday and although I could ssh into it it was complaining that it couldn't write to the access logs when I stopped and started apache. I elected to reboot the machine but the machine no longer boots linux although it will be boot the Windows partition if you wait long enough. (i suspect Windows is running scandisk.exe 'cause it thinks something is wrong) I put in the Kubutu 6.06 server CD and tried to start a rescue session. Althought it boots it wouldn't boot of any of the partitions (my knowledge getting a little fuzzy here). At one point I tried starting the partitioner but the machine seemed to lock up so I had to switch the power button. So I put in a Damn Small Linux Live CD (kernel 2.4.26) and it boots ups fine, sets up X windows etc. I can mount /dev/hda8 fine which is my home partition but it won't mount /dev/hda7 which is the root partition and inconveniently containing the data I wish to recover. When I run e2fsck /dev/hda7 it exits early saying its a short session and asks is it a zero length partition? I run fdisk and the stop and start segments, sectors? seem in proportion to the partition size (about 10G). I've tried running fsck.ext2 -b 8913 /dev/hda7 but it still complains that it can't find the superblock and makes ominous suggestions that the partition might be corrupt. I have been running badblocks /dev/hda7 for the past hour or so but nothing salient seems to be reported. My plan was to image the partition and mount on another machine to recover the database but this now seems hopeful. Do the sys admin guru's out there have any suggestions? Thanks Chris

Update on SCO trials
by Ian McDonald 15 Jul '07

15 Jul '07

For those interested have a look at: http://www.groklaw.net/article.php?story=20070715072440971 Basically trials probably start September. People seem to have stopped worrying about all of this though as Microsoft is now a bigger (and more realistic) threat. -- Web: http://wand.net.nz/~iam4/ Blog: http://iansblog.jandi.co.nz WAND Network Research Group

Samba move to GPL 3
by Ian McDonald 10 Jul '07

10 Jul '07

Samba has announced that they are moving to GPL3. http://news.samba.org/announcements/samba_gplv3/ This is the first major project to go across to GPL3 and this will make things interesting potentially for Novell with their agreement with Microsoft. For one thing this will keep the lawyers busy at large technology providers if nothing else! -- Web: http://wand.net.nz/~iam4/ Blog: http://iansblog.jandi.co.nz WAND Network Research Group

Re: [wlug] wireless connection

Whilst I do have a gui manager for networking it is not like the one shown in the link. One clicks on the name of the network shown and a drop down with any other access is shown. I _think_ the the key is WEP simply one word <ultra> I will I try the command line. should that fail I guess I need to install network manager,hopefully I can get it through apt. I did not do this before as I thought it may cause a conflict with the ndis wrapper.

This is the output from: iwlist eth1 scanning ESSID "martin" Protocol IEEE 802.11g Frequency: 2.412ghz Channel 1 Quality: 0/100 Signal level 64dbm: 256dbm Encryption key: on Bit rates 1-2-5.5-11.6-9-12-24-36-48-54MBS Extra:bin_int=100 Extra:ati=0 I have never had a problem with open access points so I wonder if I am incorrectly entering the key somehow ( does it need to be entered twice with a space/dash?) The key is a simple 5 letter dictionary word so I assume that it would be ascii though I did try the hexadecimal entry also. I can ping the router under windows with round trips under 2ms When i ping with ubuntu I get network unreachable.
