I REALLY like secure shell (SSH) for remote access to linux machines. You can do more than just a “telnet” like remote shell with it. (Port forwarding.) However, the default configuraton for the openssh-server is sometimes a bit less tight than I would like. For that reason on a new install, I usually like to make a few changes. I don’t know if I’ve mentioned this before, but I haven’t devoted a post JUST to this, so… here we go.

Exporting an active linux desktop with vnc, or vnc remote desktop under linux
There are lots of ways to get a remote desktop under linux, remote X, nxserver, vnc. One of the problems though is the most common configuration doesn’t let you connect to a running desktop session. There is a vnc component that let’s you do this and I’m using it right now. On the home network, sometimes I don’t want to be sitting at the desktop machine and would rather use the laptop while checking in on programs running on the desktop itself. But, being too lazy to go to the desktop it would be nice if there was a way I could run something remotely that would let me view that desktop… ahhh there is a way.

Network Security guide for the home or small business network – Part 6 – Secure your services
This one is going to be tougher. Of what we’ve looked at so far this will probably take more work and learning than any of the others. The good news is, depending on your situation you may need to do less here. IF you have decided that your pc (or network) has ports open to the outside world, so that incoming connections can be listened for. You NEED to do this. For every service that is accessible from the outside world…

How-to – NXserver on OpenSUSE
I’ve played around with NXserver before and been impressed with it’s speed (and quality) of remote X desktop over slow connections. It’s been about a year since I’ve actively looked at it, but I found this how-to yesterday from madpenguin. The how-to is related to getting nxserver up and running on OpenSuSE using freenx (a free version of NoMachine’s NX server).

10 things to do before hooking a Linux PC up to the net
An editor at tech republic gave a challange not too long ago to Linux users to step up and offer articles along the lines of the top 10 things to do before hooking a linux pc up to the internet. Click to read the first of these submissions (I don’t know if there will be more featured, but more are viewable here.)

Samba (Windows) domain controller using ubuntu linux
There’s a good how-to at (where else) howtoforge.com on the topic of setting up ubuntu Linux (with samba) as a Primary domain controller for your network of windows machines. This uses tdb instead of LDAP and is suitable for networks with up to 250 users. The advantage here is that it’s simpler to setup than LDAP integration. Of course, samba for simple file/print sharing is fairly easy to setup, the domain controller “stuff” is usually a bit tricker.

SSH tips and tricks.
This linux.com article will make a handy reference for anyone who’s a bit fuzzy on what ssh can do other than just something that looks like telnet, although encrypted from end to end. It’s from their CLI Magic series. Among the topics covered.

Ultravnc for remote computer support
A little while back I talked some about TightVNC which for a long time has been my favorite implementation of a remote framebuffer, or remote desktop viewing protocol known as VNC (Virtual Network Computing.) The original VNC (now realvnc) came out of AT&T research labs in the UK and has developed quite a following as a pcanywhere alternative depending on what you need to do. Now, tightvnc has been a favorite of mine for a couple reasons. 1) it’s well supported under linux which is a must for me…, 2) it excels at slower speed connections. Which is also fairly important to me.

VNC or Tightvnc for remote pc access
I was surprised to do a search and find that I haven’t mentioned tightvnc before (or even merely VNC as a useful tool.) Ok – here’s the scenario, you need a way to get remote pc access, or remotely view a desktop, maybe it’s a Windows machine and you’re using a Mac? Or Maybe it’s a Mac and you have a linux desktop? Or a Linux server from a Windows machine? Most of the time in the Windows to Windows remote control area the choice becomes either Remote Desktop, or PCAnywhere. There are other options though. One that I’m particularly found of is TightVNC, which is an implementation of the VNC protocol (VNC stands for Virtual Network Computing).

Linux on a Linksys wireless router
This is one of those projects I’ve been tempted to undertake for some time… Newsforge has an article on Linux on the Linksys wireless WRT54G and WRT54GS routers. The distribution designed for it is openwrt which is an embedded linux flavor.
