Crazy question
by Peter 23 Jun '06

23 Jun '06

In a shop run by a friend, and he said his machine was behaving oddly. To his surprise, he had a 120G drive, but from the windows disk utility, there was only 30 in a partion, Drive C, and the rest as unallocated space. He did not know how this had happened or when, but was fairly sure it had not been bought set up like this. He is also getting notices on the screen that memory dumps are happening. He is firewalled and anti virused and updated. But he doesn't have specific anti spyware. Question: have you ever heard of anything like this happening as the result of an infection? Is it a reasonable investigative first step to boot from a live Linux CD and find out if it shows up as unallocated space in that too? And what would you then advise using to see if the space really is unallocated and with nothing in it? I have system rescue CD, and could get any of the other security oriented distros, but this isn't really my area.... Peter

How to check for packet loss over a long[ish] period?
by chrisisbd＠leary.csoft.net 22 Jun '06

22 Jun '06

I want to run some checks on my ADSL connection to see what sort of level (if any) of packet loss I am getting. In particular I want to run some checks in the small hours of the morning because I'm getting some rsync errors which might be due to packet loss. What tools are available for checking packet loss? Is there anything better than 'ping' and/or what is a civilised repeat rate to use with ping to avoid it being seen as a DoS attack? The system I'm rsync'ing with does respond to 'ping' so that's a start. -- Chris Green (chrisisbd(a)leary.csoft.net)

Strange hardware problem
by Wayne Stallwood 22 Jun '06

22 Jun '06

We have a server at a clients that has been showing random signs of instability (random reboots and a couple of panics) Suspecting hardware problems I brought it down and ran memtest86 on it. Then something odd happened. Memtest shows plenty of memory errors, spreading over pretty much the whole of the installed 512MB. When I stopped the tests halfway through the first pass there were two pages, the lowest error was at about 50MB the highest was at circa 430 But the really strange thing is that the error bits are 00000000 i.e the test data and "bad" data match perfectly. There is no ECC on this machine so how can the data I put in the memory and the data I take out be the same yet there be a memory error. Memtest clearly shows the "good" and "bad" column with matching data but still flags these as errors. I have ordered replacement RAM anyway, but I was just interested in what other type of memory error I am seeing here ?

Wierd DNS problem
by chrisisbd＠leary.csoft.net 20 Jun '06

20 Jun '06

We have a wierd DNS problem at work, it's almost certainly something to do with low level DNS setup and/or the firewall but we're a bit lost as to where to look. >From our Solaris boxes issuing an 'nslookup xxx.yyy.zzz' gives the correct IP address for the domain xxx.yyy.zzz. However every application lookup of domain name xxx.yyy.zzz gives the wrong result. The wron result is always that of a domain at Network Solutions, a US name registration business. DNS works OK from PCs on the network. So it looks like something adrift on our name lookup machine but we really cannot see what at the moment. When an application asks for a name resolution what is the normal order of things happening? -- Chris Green (chrisisbd(a)leary.csoft.net)

Disk usage
by Wayne Stallwood 19 Jun '06

19 Jun '06

I think this question may have come up on the list before, but I can't find an answer in the archives. /dev/sda3 111G 102G 3.1G 98% /home Why is my free space only shown as 3.1G if I have used 102G out of 111 ? BTW Windows Vista is a disk space hog, a clean installation into a virtual machine took 8GB (minus 840MB for virtual memory) That's before you add any apps (and office 12 is Huge)

Weekly IRC reminder
by Brett Parker 19 Jun '06

19 Jun '06

This is the automated ALUG IRC meeting reminder sent to remind you that there is an IRC meeting tonight (Monday) at 8.00pm. Historically, these used to be the only time a lot of us would be about, now the channel has some usual faces that are there most of the time (except at silly o'clock, when we might be sleeping, or on the second thursday of the month, where we might be drinking in the Reindeer), so don't feel limited to visit during this time, come visit us when ever you feel like it! The meeting takes place on the irc server irc.alug.org.uk in the #alug channel. Most IRC clients should allow you to get there with the commands "/server irc.alug.org.uk" and "/join #alug". Popular IRC clients include xchat, irssi and EPIC on Unix, and Mirc under windows. Here are some links to help you get started with irc. Unix http://www.xchat.org/ http://www.irssi.org/ http://www.epicsol.org/ Windows http://www.mirc.com (loads of help with irc for newbies!)

Dual boot woes
by Simon Jude 15 Jun '06

15 Jun '06

Hello, Please can I pick peoples brains?! I've managed to kill off my MBR during a linux install on a machine with XP on it. I initially installed Fedora and got Grub error 17 messages on bootup. I've since installed Suse10 on it but get the same problem (error 18 this time). Evidently I should be able to install lilo from suse but this gives errors. I've also tried the XP recovery disk to fix the mbr but it doesn't recognise my password (a normal user with admin privilages). Can anybody possibly suggest a fix to this?! Thanks Simon

Lifetime of CD/DVDs?
by Ted.Harding＠nessie.mcc.ac.uk 15 Jun '06

15 Jun '06

Hi Folks, I often to use CDs to back up archival files. No problems so far. However, I've heard tell that CDs can degrade over time and that times of the order of 4 years might be the point where they start to get dodgy. Is this the case? If so, does it vary with the brand/type of CD? And does something similar apply to DVDs? Thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 09-Jun-06 Time: 19:30:10 ------------------------------ XFMail ------------------------------
