All,

Would it be possible to mask ip information lets say 192.168.1.1 to xxx.xxx.1.1 from the terminal?


Have been attempting variations of:

cat /etc/sysconfig/iptables | sed 's/\b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.\b/xxx.xxx./g'

tried ' and ", sed -i, sed -e, /g or global and without...
but it doesn't appear to be changing the output.

Does it have to output to a file? Was hoping to throw this in an sh and email the output without having to > some.txt and then rm'ing it as this adds alerts from AIDE

Thoughts?

Thanks in advance

Try this:

Thanks all

got it with this:

cat /etc/sysconfig/iptables | sed -r 's/[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\./xxx.xxx.xxx./g'

output all ipv4's to xxx.xxx.xxx.1

or

cat /etc/sysconfig/iptables | sed -r 's/[0-9]{1,3}\.[0-9]{1,3}\./xxx.xxx.xxx./g'

output all ipv4's to xxx.xxx.1.1

can be used to obfuscate all sorts of logs and files, very nice

wonder if I can place this on the mail relay to edit all outgoing email subjects and bodies.

now to figure out the ipv6 version of this for ipv6tables.

Thanks again

oops for the second example:

cat /etc/sysconfig/iptables | sed -r 's/[0-9]{1,3}\.[0-9]{1,3}\./xxx.xxx.xxx./g'

should have been:

cat /etc/sysconfig/iptables | sed -r 's/[0-9]{1,3}\.[0-9]{1,3}\./xxx.xxx./g'
