ISP status monitoring.
I'm giving this a whirl on debian-isp as I figure its subscribers have the most experience with this. I'm looking into setuping up network monitoring on one of my home boxes to keep my cable ISP (Cox/Road Runner) honest. I'd like to check basic connectivity and DNS service up/down/speed at a minimum and bandwidth if possible. I've read a bit about Big Brother and Spong. I was wondering if any of you have recommendations for either or others I'm not aware of. Also, some advice on configuring this to monitor nicely. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Perl 5.6
Hi *,
I need to get Perl 5.6 installed on Potato. Of course, I don't want to break
anything important. Any idea?
Sorry if it's a little off-topic but this is the only debian mailing list I am
subscribed to.
Haim.

you may need to set the Referer: header in the HTTP request. some cgi
scripts check the referer...(yes, that's pointless and stupid, but it's
quite common).
and set the user agent to something like:
$ua->agent('Mozilla/4.51 (Macintosh; I; PPC)');
i generally use netscape on mac as my user-agent in web robots because:
a) moronic sites generally don't block netscape on macintosh
(i have seen some sites that block netscape on linux with a stupid
message like "sorry, we don't support your browser/operating-system".
unfortunately, brain-dead web design is not yet a capital crime)
b) said moronic sites generally wont output moronic IE-specific junk
if they detect netscape. sometimes. if you're lucky.
btw, the perl HTML::TokeParser module is excellent for extracting stuff
from web pages. i used this (plus LWP::UserAgent, HTTP::Cookies, and
HTTP::Request) to write a wrapper script for searching the Melbourne
Trading Post site, which is one of the most brain-dead cretinous sites
i've ever had the misfortune of having to use.
there's also HTML::TableExtract for getting data out of html tables.
these modules are all packaged for debian.

e2fsck error
A short while ago, my web server went offline and is now reporting a superblock error on /dev/hdc1 (/var) and suggests using e2fsck -b 8193 option. I do not know enough about the ext2 system to know what super block numbers to try. Can anyone suggest the correct numbers or how to find out?

You would have to recalculate every checksum block but as I see it, it would be possible to do this on a row by row basis, and also keep a working copy of every row + a counter on a different disk or possibly way back on the new disk. So if the old system looked like this 0 1 X X 2 3 4 X 5 6 7 X X 8 9 . During rebuild you would have this: 0 1 2 X X 3 4 5 6 X 7 8 <- row you are writing 6 7 X Z Old raid + new empty blocks X 8 9 Z ... As soon as you have traversed more than in this case 2 rows you would not even need a backup copy of the blocks, only a counter of how far you have gone. This would have to be held on disk though, and all disk writes mush be synchronous to ensure that the data is safe in case of powerfail or system crash. It should really be possible to do this rebuild in a running raid system (if the rebuild process is done from the raid5 driver) , as long as you keep track of how far the rebuild has gone and lock the row in progress + in the beginning you need to lock the first rows from access. What I am worried more in this case is how the mke2fs optimisations for a raid device will affect performance if you do this repeatedly, or will a "defrag" of the raid device after this rebuid solve it? /Roger -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
