How can I open a range of ports in ubuntu using (g)ufw for use with membase?

Question

I have membase (membase.org) installed and I have to open a bunch of ports in order for the cluster to function

Adding the single ports was easy enough but I can't work out how to open the range 11200-11299

Answer 1

You can specify port ranges to ufw (the command-line one), using : (colon) to separate the lowest and the highest port in the range. For example:

ufw allow 11200:11299/tcp

Note that the protocol part (/tcp or /udp) is mandatory with port ranges.

This works at least since Ubuntu 10.04.

Answer 2

I believe you can specify the range in the last tab of new rule, tick the checkbox at the bottom of the window to add more options (just to be safe). The range can be specified as 1000:1010 to open ports 1000-1010.

Answer 3

The cleanest command line way I've seen is a little script like this:

for i in `seq 11200 11299`; do
  ufw allow $i
done
