Well, this can be done with IPChains... the "-l" option will log all
packets. So, if you are interested in logging packets to from your network
to port 80, I would try:
/sbin/ipchains -N weblog
/sbin/ipchains -I forward 1 -j weblog
/sbin/ipchains -A weblog -s $internal_net --dport 80 -j RETURN -l
/sbin/ipchains -A weblog -s $internal_net --dport 443 -j RETURN -l # for
https
This will output to kernel logs. Unfortunately it doens't resolve names or
make stuff very pretty, but many frontends for ipchains logs can be found
on the 'Net and many of them even email the output to you in pretty colored
HTML tables.
I use logcheck but it blows. Look for something better at freshmeat.net or
your favorite Linux software site.
Of course, getting a proxy might serve this better, as this will (as your
question requested) give web *sites* but not URLs or content details. This
would be easier to do using a proxy, which is made for many reasons
including this. Or, maybe tcpdump could be used in conjunction with perl
-- a do-it-yourself job, to give you nice URLs and maybe even link to
IPchains to do content filtering.
There's probably software out there that already does this though.
Cheers,
John

It sounds like this is not an issue with vi, but rather with the newline
character for UNIX and DOS. If you write a file in linux it will be written
with the newlines in UNIX format, then when you open them in windows the
newlines will be DOS style. Look for a converter (freshmeat.net, search for
linebreak), or write one yourself (perl or C would both be pretty quick). To
find out the newline char, use a hex editor.
Hope it helps,

Subject: How can I get/set maximum number of processes on RH6.0 (plus some other stuff.
Date: Sat, 26 Aug 2000 09:11:53 +0100
Hello all,
Can anyone tell me how to find out the maximum number of processes
supported on RH6.0. I wrote a little program that madly creates threads
(just to see) and ran top. My program seems to stop creating when top reads
301 processes.
Is there a place where I can read (preferably from withing a program) the
process limit. I've looked through limits.h etc and although I can find a
pthread limit of 1024 (In limits_local or something similar) I can't find a
process limit (which in Linux threads I guess should be the same). I'd like
to be able to increase the limit if possible too (unless this is a BAD
idea - to many processes wasting time and all that).
Secondly is there a similar place to find info on the maximum number of open
file descriptors (and connected sockets if the number is different than the
fd number).
The reason for these questions is that I'm writing an application that is
required to support *LOTS* of simultaneous connections (probably greater
that 256 in and 256 out). Of course one standard way to support many
connections is to create a new thread per connection, problem is that this
starts to go a bit pear shaped when the numbers get big.
I'd like to use a thread pool, but they only seem good if you want to limit
the number of connections (say by running accept in the body of *n* threads
where *n* is the max number of connections). The only other option I can see
is to use non-blocking IO and select, which I'd rather not do if possible
(it's not that I don't know how to more the case that I'd like to figure the
problem out using threads first).
Finally (yeah I know that I've gone a bit off the original heading :-) )
does anyone know if there is any info available relating to the relative
costs of various glibc functions and their thread-safe equivalents -
allocating memory seems to be the worst culprit (unsurprisingly) but I'd
kind of like to know so that I can pre-allocate and pre-whatever if posible
to minimise the real run-time overheads of using threads.
Thanks in advance for any answers to the above.
Best regards to all, Fraser.

If a software developer wanted the files generated by their programs to be
useless to anything but their own brand of software, using the XML file
format to save the data won't help make the data useful to any competing
software. Some may say at least the file is stored in a standard format,
but experience proves that if you can not interpret the data, the format is
useless anyway. Some say at least you can still parse it, but experience
still proves that the data is useless if you can not interpret it. Since
this format does have an overhead that consumes real resources, you not only
not gain anything by an non-portable XML file, you in fact lose resources.
In the business world this would add up to real money lost.
One of the most foolish claims in this thread was the one that XML make Mac
OS X bundles so great. XML provides nothing in that situation it is simply
the data format the Apple seletect to use. Just about any other format
could have done the job as well, it is the algorithms and the packing of the
bundles and the data stored about the bundles that make the difference.
Does anyone seriously believe that if Apple had chosen another data format
instead of XML, that it would have made any difference is the functionality
of the bundles?
Would using XML formatted data make RPM or DEB packages any better or worse?
In a word, NO.
It seems that too many people are so worked up about the XML format that
they are crediting it with magical properties.

i think ur hardisk is bigger than 8.4Mb, and linux may have problem
accessing beyond 1024 cylinders.
to solve the problem, boot up using ur floppy
edit the file /etc/lilo.conf
there should be a option linear in the file, change it to lba32
if not, just added lba32 in
after that, do a
/sbin/lilo
reboot after that.

That tends to be the aim of competing commercial proprietary systems anyway.

I suspect it's all part of webifying data, the road to XHTML.

I agree with you XML should stick to database type info and leave binary type
info to another format.

Because rxvt doesn't link libXt (for reaosns of speed and size),

if you want i a way to monitor the web traffic with smaller more readable
logs than you should try to install squid as an transparent proxy. it has
logging and access controll functions especially for http. And when you use
it as an transparent proxy, your clients will not know that they connect
over an proxy and must not change any proxy options.

Is the tapedrive located at id:0 ?
If not you might want to check cables, termination, etc.
Check so that you don't terminate the bus on a device in the
middle of the chain, e.g. harddrive or cd-rom.

I would suggest that you enable Target Disconnect on the tape-drive's
scsi id. I don't know if that is possible on the 7850 controller but
its possible on the 7860 so it should.
Disconnect needs to be set on slower devices such as tape-drives so
that the controller can tend to other requests from e.g. harddrives.
If this is not set the controller stay's connected to the tape-drive
until the tape-drive is finished.
The reason for this is that only two devices can talk on the scsi-bus
at the same time and one is always the controller.
