SSH, Proxies (Proxy’s?), Tor and Web Browsing

Wednesday, February 4th, 2009

For quite some time I’ve been making use of a dd-wrt modified linksys box on my home network as an openvpn endpoint so that when I’m out and about in the world, I connect the vpn, switch firefox to route through a squid proxy server on the home network and I’ve got a nice fairly [...]

Handy DNS tools online

Monday, January 29th, 2007

There are some tools that I make use of almost daily. Either because something strikes my curiousity or because of necessity to find out a bit more about a computer issue. DNS lookup tools fall into the category of “must have” for the kind of stuff I wind up doing. Whether it’s a whois lookup [...]

Encrypting wireless traffic

Thursday, August 17th, 2006 has been running their security tip a day this month and I really liked this one. It’s essentially a way to encrypt your wireless traffic using ssh. That’s something I’ve covered here before, but it’s worth reminding that it’s possible and a good idea.    Send article as PDF   

Wget user agent avoidance

Friday, August 4th, 2006

I use wget a LOT. Many times in working with a website I’ve got a ssh console opened to the site and if there’s a plugin that I’d like to download it doesn’t make sense to download and then upload, I want to just download it directly from webserver to the website where it [...]

Banks and Web security

Tuesday, August 1st, 2006

George Ou has a good post on Banks cheating their way to meet web security guidelines. Many of the observations that he notes come from the Between the Lines column here and are SPOT ON. The biggest I see is related to “multifactor authentication”….    Send article as PDF

IPtables magic, or… Blocking Aggressive Outbound Traffic with IPtables

Sunday, July 16th, 2006

Blocking Aggressive Outbound Traffic with IPtables. For starters, I’ve tested this on a test system that started out with NO iptables rules, and then moved on to an IPCop install (the vmware download from…) I’ve detailed previously one dilemma that I had with regard to my own cable connection which made me question how [...]

Firewall musings…

Friday, July 14th, 2006

Yesterday I had a bit of a realization. I had just been looking at a wireless router/firewall setup and was thinking about the firewalling rules (which seemed to be geared at the WIRELESS lan… i.e. blocking that activity on the Wireless segment.) You know, traditionally firewalls have had the attitude of defending the internal network [...]

Wednesday, July 12th, 2006

Sans also brings this story about the Debian development server being compromised. Investigation is ongoing. The machine was and hosted CVS among other things (ddtp, lintian, people, popcon, planet, ports, release). It has been taken offline currently for a reinstall, other systems have been locked down until they can patch the vulnerability that they [...]

Rsync for easy (and quick) backups

Monday, July 10th, 2006

I’ve got to say, I haven’t spent ENOUGH time with rsync to really be fluent in how I could put it to use…. A week or so ago I was reading this list of essential Linux software by a guy that moved from Mac OS X to linux because he detested the DRM that was [...]
