A couple days ago I had a brief article on the vandals banging away at the door of my ssh server. Like I said, I’ve, at times, been fairly smug abou the futility of their actions, but…. the persistance concerns me. Let me be more specific, I keep a fairly tight ssh server setup (don’t […]

Sometimes I wish I wasn’t curious about things…. The other night I was working on something on the testbox in the back room and saw the switch lights flickering fairly actively between the server and the internet gateway. At first I thought maybe it was some mail coming in, but it was awfully persistent. So, […]

Well, I’ve got a nice way of doing “easy” one click (or one cut and paste) light desktop support for windows or linux, one uses ultravnc sc, the other uses x11vnc with a special wrapper script. So, what security flaws are there in this process? Well, for starters, I see the biggest vulnerability for the […]

I’ve got to say, one of the things I really like about linux are the myriad of options for remotely administering a system. SSH is the one I use the most, but for the graphical you have x (especially on the LAN), nxserver (which is a compressed and optionally encrypted wrapper of the X protocol….), […]

(Or command line SSH access […]

I thought this was a great idea…. rsync.net Okay for 2$ per GB of storage per month (or $24 per year for 1GB of storage) you can have your very own secure online storage drive. For you windows users think of a G: drive or a Z: drive that you could SECURELY connect to from […]

When a machine has been arp spoofed, ALL network traffic from it is likely passing through a “hostile” machine. So, NO, https and ssh traffic is not immune, it is travelling through a hostile machine. However, it should be encrypted. There are a few exceptions though. SSH version 1 is a broken encryption scheme and […]

This really could be used to encyrpt web traffic over any “hostile” network. Here’s what I’m talking about. Laptop using wireless. Within our internal network we would LIKE all our web traffic to be encrypted at least from the laptop to a wired host. (From there to the outside world it will be open.) At […]

Along the lines of “knowing your network” with the network security guide. Here are some of the most commonly used network ports. There are 65535 ports that can listen for a connection, so this is not a thorough listing. (These are tcp unless noted otherwise.) Send article as PDF

I support a few linux systems outside my own group. Those systems are not as quick to get upgraded to the latest and greatest version of Mandrake – now Mandriva as my home systems. But, I occasionally need to build rpms for them. I don’t want to have a build environment on each one and […]
