Installing FreeNX Server on SUSE 10 |
| Post date: December 27, 2005, 15:12 Category: Network Views: 4590 Comments: 0 |
| Tutorial quote: Not long ago, I reviewed SUSE Linux 10 and found that they had included the latest version of FreeNX (a free version of NoMachine's NX Server) on the installation media. I'd never really tried FreeNX at that point but had heard some good things about it, so I thought I'd give it a shot. Well, once it was installed and working I have to say I was immediately impressed by how simple it was to setup and how well (read: fast) it performed over a WAN connection. I was literally able to get my desktop at home from anywhere else in the world and get near-local speed. Normally, working on a remote system is alright until you need to type in any shape or form. There was almost no delay from the time I'd press a key to the time it would show up on the screen. This is what sold me on FreeNX and prompted me to offer to write a HOWTO on the topic. I was overwhelmed with email from our readers asking that I write it... so here we are! |

| Tutorial quote: Linux has a number of useful bandwidth monitoring and management programs. A quick search on Freshmeat.net for bandwidth returns a number of applications.

Using iptables to rate-limit incoming connections |
| Post date: December 16, 2005, 22:12 Category: Network Views: 1778 Comments: 0 |
Tutorial quote: There are times when you have to allow arbitary incoming connections, when you are travelling for example.
In these situations you can open up your system to allow incoming connections and be the target of a dictionary attack - literally a machine trying to connect and login over and over again using usernames and passwords from a dictionary.
In this situation you can create a collection of firewalling rules which will deny access from remote clients who attempt to connect "too many" times. |
