Windows machines.. sigh

On August 25, 2007, In Weblog, by Remko

Lately I have been confronted by Windows machine administration again, mostly at home. I thought I had setup everything so that it does most things that I authorized, and all the others where difficult questions that no one actually understands (And thus reports to me before taking actions). Sadly one of the machines didn’t seem to enjoy that part of my game and decided to go on a trip of his own. It was immediately visible through Internet Explo{r|d}er, a bogus application was loaded and some interesting products where running in the Windows Taskbar / Taskmanager. You where not allowed to kill them (bright ray of light should shine on you now) so something really fishy going on. (SIMBAR is one of the bogus applications btw; a lot of people have that enabled, and still wonder why they are getting those strange spamish messages on screen, oh well it’s all about being carefull!)I decided to install my trustworthy Hitman Pro (www.hitmanpro.nl yeah seems to be developed by a countryman) and installed all the suggested applications. Soon more then 100 bogus entries in the registry and files were discovered.I’ll guess I need to start informing my people again (at home, and around me). BE CAREFUL IN WHAT YOU INSTALL, will be the motto. I will also try and find some applications that can properly defend the perimeter in my home and for the people around me, so that they dont have much to say about what is installed, and should ask around first. This might reduce the user experience, but can save me a lot of time :-) Oh well, lets get rid of this junk and play with MacOSX, and my FreeBSD servers again ;-)   (more…)

Soekris 5501 up and running

On August 20, 2007, In FreeBSD, by Remko

Well, After fiddling around for a little I managed to get my new Soekris 5501 up and running this weekend; I am not  using it production wise yet (I need to move my adsl-router to bridged mode and uplink the Soekris to the adsl-router), but it is running which some default packages now.

It's a really new phase for me to have disks mounted ro instead of rw (well at work we have a lot of firewalls which are mounted ro, but that is an entire different setting for me :-) ) so I needed to watch around a bit to mount partions rw every now and then (to finalize the rc.conf etc).

I used TinyBSD to do the initial installation after some patches from Richard Arends [ which are pending Release Engineering Team approval btw; see my queue for the patches and information ].

I needed to adopt /boot/loader.conf and insert console="comconsole,vidconsole" in that, because otherwise I would not see anything after the regular boot. I also enabled the /etc/ttys part for ttyd0 so that I can actually use a serial line to logon. Sadly that is now running at 9600bps while the rest of the serial part is running much faster, so i need to adjust that a bit more. Another thing that I found out is that you should not use an AMD64 machine to produce the binaries for the Soekris [i386 device], because that does not work, or at least I could not get it to work, even with TARGET_ARCH=i386 set (some compiler issues that told me to bugger off :-) ). But VMware to the rescue and I now have a fully loaded Soekris. See the DMESG below for the standard detection of things [ with the TinyBSD build ofcourse ]:

Goodbye logtransfer, hello rsync

On August 1, 2007, In Technical, by Remko

For long I used a little script called logtransfer, which is just a stupid script that scp's files over *2007-07-01* for example, but that wasn't very flexible anymore. I setup rsync with some modules that enable me to transfer the logfiles in an almost similiar setup as before, but now with partial filetransfer support (continue where the beast stopped, to prevent unneeded transfers), deletion support (that if files are gone, they are removed locally as well, I wont do that before I made backups on DVD ofcourse).

This generates much more flexibility for me, because filenames can change, things can get deleted by hand, etc and that is taken into account now (I realise that this is not something everyone want to persue, but I do :) ).

Backups are now in quicker; more complete and more well, my stylish. No more need to maintain scripts myself; but just use standard tools already available that do the job very well.

(Oh, ofcourse I use rsync for much more then just my backups and logfiletransfers, I use it for the Honeynet project, mirroring my webtrees to an offsite location, making sure that my patches on the FreeBSD cluster are synchronised with my local tree etc).

Example rsync usage that I do  now:

/usr/local/bin/rsync --ignore-errors -av --partial --delete remotehost::modulename targetdirectory

(more...)
