ftp - Are there any free software to test web server?





I wrote own http server. Are there any free software, test packages
or toolset to validate whether it complies fully or partially with HTTP 1.0 (rfc 1945).
And moreover it'd great if this software could estimate http performance and check for
potential security issues. The same is wanted from this software in respect of FTP
compliance validation.

Lots of
questions here. While I'm sure lots of people will tell you their tool does everything
if only you will buy it, there are very few tools available which make a reasonable
attempt at any one of these.




For the
security side of things, assuming that you are only interested in serving of static
content, there is a list of useful software href="http://www.dragoslungu.com/2007/05/12/my-favorite-10-web-application-security-fuzzing-tools/"
rel="nofollow noreferrer">here.



For
capacity testing you could use ab which ships with apache. You might also consider
scripting more complex interactions using loadrunner ($$$) or href="http://www.perl.com/lpt/a/845" rel="nofollow noreferrer">http::Recorder and
www::mechanize



Most of the large
software packages available as source code come with automatic testing scripts (usually
a target in the Makefile, e.g. 'make test') but the Apache build instructions don't
mention this - might be worth downloading the src and configuring it to see if it does
have test scripts included which could be adapted.



As for performance testing/monitoring - IME
there's nothing currently available which is any good (and I include Oracle's Grid
Control, BMC Patrol, Google Analytics and a large number of other products in the 'not
any good' category). Personally I'm using a home-grown solution which relies on very
detailled logging of URL generation (have a look at mod_log_config %D option and
mod_log_firstbyte).



One area I've not studied
in great depth is passive monitoring - there are tools like href="http://www.amasol.de/sicoms/pictures/download/12_reasons_to_choose_Vantage_AM.pdf"
rel="nofollow noreferrer">vantage agentless but these are very, VERY
expensive. href="http://pastmon.sourceforge.net/Wikka-1.1.6.5/wikka.php?wakka=HomePage"
rel="nofollow noreferrer">PastMon may meet your requirements (its good and
its free) but you're going to need some specialist and expensive hardware to run it on
if you expect to measure what happens when your webserver reaches
saturation.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...
