Hi All.

I am Aussie living in London. Network Admin, and we've just decided to use Nagios on Fedora Core 6 for network monitoring and geeeez the learning curve is steep.

Im pretty keen to get good at this linux stuff - i've always liked "first principles" but it's very trying.

 

looking forward to participating here :)

As a network admin, you might be interested in Linux Network Admin Guide (or the NAG), which was good enough it actually made it into print with O'Reilly.

 

Useful utilities for a network admin:

• tcpdump - raw network traffic
  
  
• nmap - network mapping utility (security scanner)
  
  
• ethereal/wireshark - network analyzer (better than tcpdump)
  
  
• ntop - show network usage sort of like top does
  
  
• multi router traffic grapher (mrtg) - sexy graphs for your network usage.
  
  
• big brother - network/service monitor
  
  
• nagios - you know this one already sort of
  
  

just some ideas for you to poke around in :)

 

enjoy the forums, ask questions! ;)

I am also a newbie and interested in Learning Linux.

 

 

As am also a Network Eng, suggested tools will be of great use for me.. Thanks... :)

I have installed Nagios on my Fedora 6 and I want to configure Nagat too. Searched lot.. But no efficient documentation...

Can anyone guide me on this?

Dunno about Nagat, but in terms of network tools:

 

snmpd for network monitoring (including router, etc)

mrtg to report results in a browser

nagios to show multi-server results (multiple MRTGs in effect)

cacti for nice graphs

 

awstats to graph results of logfiles, such as apache/ftp/mail/etc

 

Erm... and the other networky tools:

iptables for Firewalls/NAT

tc for Traffic control (traffic shaping)

tcpdump to sniff packets

nmap to port-scan boxen

 

Others (ifconfig/ip/netstat/host/nslookup) you'll probably know.
