Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

For machines that have many ip blocks spanning different Class C's, this will show which ones.

for i in `lanscan -i | awk '{print $1}'` ; do ifconfig $i ; done 2> /dev/null
netstat -nr|egrep -v "Routing|Interface|lo0"|awk '{print $5}'|sort -u| while read l; do ifconfig $l ; echo " Station Addr: `lanscan -ia|grep "$l "|cut -d ' ' -f 1`" ; done
host `hostname` | rev | cut -d' ' f1 | rev

Gives the DNS listed IP for the host you're on... or replace `hostname` with any other host

ifconfig | egrep -A2 "eth|wlan" | tr -d "\n"| sed 's/\-\-/\n/g'|awk '{print "mac: "$5 " " $7}' | sed 's/addr:/addr: /g'
ifconfig | head -n 2 | tr -d '\n' | sed -n 's/.*\(00:[^ ]*\).*\(adr:[^ ]*\).*/mac:\1 - \2/p'

Is the better option on a Open SuSE Box

Returns the IP, broadcast, and subnet mask of your interfaces absent any other extraneous info.

I know it's a bit lame, but I've created an alias for this when I *quickly* want to know what a system's IP is. Small amounts of time add up :)

ifconfig eth0 | grep HW | cut -d " " -f 11
ifconfig | awk -F"[: ]+" '/inet addr/ {print $4}'
ifconfig | grep "inet" | tail -1 | awk '{print $2}'
ifconfig | grep "inet" | grep "broadcast" | awk '{print $2}'
ifconfig | grep "inet addr" | cut -d":" -f2 | cut -d" " -f1
for i in `netstat -rn|egrep -v "Interface|Routing"|awk '{print $5}'`;do ifconfig $i;done
ifconfig | awk '/inet / {sub(/addr:/, "", $2); print $2}'
watch -n 2 -d '/sbin/ifconfig eth0'
ifconfig | awk '/HWaddr/ { print $1, $5 }'
ifconfig | grep HWaddr | awk '{print $1,$5}'
{ if (/^[A-Za-z0-9]/) { interface=$1; next } else { if (/inet [Aa][d]*r/) { split($2,ip,":") } else { next } } print interface"\t: "ip[2] }
ifconfig | grep -o "inet [^ ]*" | cut -d: -f2

This is what we use.

You can grep -v 127.0.0.1 if you wish.

ifconfig | sed -ne 's/^.*inet \(addr:\)*\([^ ]*\).*/\2/;te' -e 'd;:e' -e '/^127\./d;p'

This also works on non-Linux machines. If you have GNU sed you can do it more elegantly:

ifconfig | sed -n 's/^\s*inet \(addr:\)\?\([^\s]*\) .*/\2/;T;/^127\./d;p'
ifconfig|sed '/inet/!d;/127.0/d;/dr:\s/d;s/^.*:\(.*\)B.*$/\1/'

Shows only IP-addresses of ifconfig except 127.0.0.0/8.

I fixed the script to work on more systems and configs

short info

/inet/!d; #grep inet

/127.0/d; # grep -v 127.0

/dr:\s/d; # grep -v dr:

s/^.*:\(.*\)B.*$/\1/ # remove everything exept between : and B

ifconfig eth0 | grep -o "inet [^ ]*" | cut -d: -f2
ifconfig eth0 | awk '/inet / {print $2}' | cut -d ':' -f2
