Nothing beats practice. No amount of reading documentation and theory will teach as much as that same material combined with a system to play on. A good tutorial is even better.
This instructional page I just worked through about setting up UCSPI-TLS with Qmail was really good. It has all the steps, and they're numbered and indented. I just think it's a great format for "howto"s, because if you're discussing it with someone else, you can refer to a specific step.
(Just to be fair, I think the SSL cert business is a scam, so there.)
(I'm still setting up my system.)
I got this snazzy used Supermicro server, and after I set it up to run SSH, and I started to configure it, it started to reboot every five minutes.
Parity, in computer data, is a bit that's set or unset so the total number of bits is either even or odd. It's an extra bit, and it's added as a check on the data.
This is a simple (or simplistic) Linux GTK+ application that shows a button panel or "switchboard". Each button executes a script.
This is probably not the "best practice" but it's what I'm doing lately to migrate files between servers, desktops, etc. MS has a tool that uses DFS to migrate data and maintain UNC paths, but, whenever I see systems that map paths to physical data on Windows, I worry.
The usg-50 has a pretty flexible system for saving configurations. From the Maintenance:File Manager:Configuration File screen, you manage your configuration files.
The V1910 switch requires that all configurations be saved, or they'll be lost after a power cycle. I'm sure all users learn this pretty quickly after spending time configuring a switch, and assuming that it was saved into the switch's nvram. They unplug the switch, move it, and then discover all their work is lost.
The 108T doesn't seem to have a regular upload and download screen. Instead, it can save the configuration to a TFTP server. Talk about weird.
I think Windows sucks, but one thing is for sure - the windows are there.
You need two computers. On each set up network connections in Network Manager with IP addresses in the 192.168.1.* range.
Different admins have different conventions. Here are a list of the ones I'm going to use:
