Aeronetworks sro - Airborne Linux

Hmm, lemme see how many boring ways can we use to move files beween two computers... smbclient scp ftp webdav email attachments nc Bingo! Netcat is the most fun way! On one machine set up a listener and send its output to a file: # nc -l 1234 > filename On the other machine run a client session and send a file: # nc ip.add.re.ss 1234 < filename La voila. Now that ain't bad is it?

Network connectivity - the bane of all computer users... If I am faced with a machine with a broken network connection, I always start with a few simple tests.  First see whether the machine has an IP address, netmask and default route.  If the basics do not work, nothing else will , but it is amazing how many people do not think about that! If the basics are fine, try to do a ping of another machine - that will test most things, including the Domain Name Server.  Finally, I use Telnet to verify that the destination service is working. Doing these tests manually, will provide you with helpful error messages.    The Linux error messages always tell you *exactly* what the problem is.  If you don't understand them,  then google these messages for more information.  Another unfortunate soul likely had the same problem already.  If you use a GUI utility, then you are insulated from the error messages and you are reduced to aimlessly p...

It appears that this web site is now visible around the world.  I'll gradually repost the better Linux guides that I had on my previous web site.  A blog is a different way to present things, but it is the contents that matters and using Blogger is much less of a hassle to get the contents online, compared to my previous Apache web site.

I have operated Linux web and mail servers since about 2000.  For many years, I used a couple of 1U Dell server machines on a business DSL connection in Calgary.  Eventually, I changed to a dedicated server in a data centre in Austin, in order to get better bandwidth, but the service wasn't really any better, it just cost more, so I changed back to a DSL setup for another few years.  It worked remarkably well, and I had an uptime of more than 4 years, when a PSU eventually failed and brought the system down for a few days. About 4 years ago, I got another one of the infamous middle of the night head hunter phone calls from the other side of the globe and I set off to the UAE.  I then hastily moved my system to a data centre in Scottsdale.  It worked fine till about 3 days ago, when it suddenly fell over and the data centre proved to be rather incompetent, so I hastily moved my service to Google. So, now Aeronetworks is on Blogger and I'm trying to figure ou...

Welcome to the Aeronetworks Linux and Aircraft blog. When I need to research a Linux issue, I write up a little explanation and post it.  This way, I can refer to it myself the next time and if someone else also finds it useful, then so much the better. Over almost 20 years, my previous web site ended up with hundreds of guides, but many of them became dated.  So when my dedicated server went to computer heaven again, I started fresh. Have fun! Herman.
