Hello everyone. I was wandering about what system administration tools you people use. Tell me/us about all the important tools that you think are important in order to administrate buisiness computers in or outside of a network. Define every tool, as in why you choose that specific one, and which tools are essential in order to administrate a system/network succesfully.
In my case for my company, my most important tools in order to maintain our system are:
For the *nix boxes and network :
ping - to see if hosts are up and/or lagging
traceroute - to see which ways packets travel in order to reach their destination
ethereal/tcpdump - to see what kind of packets are in transit
rsync/tar - for backups (in my case we have a seperate backup server)
nslookup - to test and query dns
vi - edit important files, and setup scripts
ipconfig - to see and edit NIC configurations such as ip, GW, netmasks, up/down
sudo - allow certain users to perform certain administration tasks
saint - my personal favourite security testing util
nmap - just to check for open ports easily
john - detect weak passwords for our users (so i can tell them to change it if its not strong)
netstat - to monitor active connections
Xlogmaster - to see whats trying to connect to our servers and react accordingly
dns - to test and query dns
For the win boxes (mainly only clients) :
Languard - to test security from a win system (just to compare it to saint)
port-pro - to see active connections and which process they belong to.
vnc servers - to be able to administrate the clients from my box in the basement
Those are the tools i need on a daily basis in order to keep my boss happy and to make sure that our network and computers are functional. I did not include in this list programms such as AV, firewalls etc...since they are not essential administration tools.
So.......what is it that you use in order to administrate systems/networks.
