I know some network stuff but I'm often used MS$ / Windows tools ...

Is there any GUI for a "network toolbox" e.g where you can get most of all the useful network information you could possibly want?

I am looking for tools that would let me to:

1. View and set hostname + domain info
2. View (and manage) all PC's on your local LAN
3. Execute common tasks, such as PING, NETBIOS NAME, WHOIS etc etc

By the way, I've got FC2 if that would help

you can probably find all that you need. I'm not sure about an all in one program, though.

That said, for your #1, from the main menu (click the "K" or hat (depending on KDE vs Gnome desktop) button, then System Settings -> Network (enter root pw). Hostname is on the DNS tab, also DNS servers and DNS domain (DNS search path). hosts on local network and maybe not in DNS can be input at hosts tab.

For #2, it almost sounds like you're looking for some kind of Enterprise management package. Don't know about that, but VNC (vnserver running on the hosts to be managed, and nvcviewer on the managing machine) works great, something like PC Anywhere and works on both Windows & Linux. System Tools -> More System Tools -> Desktop Sharing allows setting up a client to be managed with a unique, time-limited password. What I like to do is to configure the Lisa daemon (sorry don't know a gui for this). Edit /etc/lisarc with a text editor and change the "127..." entries to reflect your local network. Then do System Settings -> Server Settings -> Services, enter root password. Scroll down to "Lisa", check it, and click start. Click the save button and exit.

Next open Konqueror and in the location bar enter "lan:/". You should be able to browse your local network. There are also other programs for this and sometimes it gets complicated browsing Windows networks.

For #3, there are a couple of gui traceroute programs under the System Tools menu. I mostly do this sort of thing from a shell prompt, so there may be lots of gui tools that I'm just ignorant of. For port scanning and network exploring in gui mode you can use nmap front-end (command nmapfe...not sure if in any menu). Very powerful.

You can try (as root, probably) yum search packagename from a shell prompt to see what's available to install. Yum is too big a subject for this post. Try also places like freshmeat.net, freshrpms.net, and rpm.livna.org to search for software that does what you need.

HTH.
