Bug Description

when displaying the IpExt values (eg. netstat -s -e --raw), some values are incorrectly displayed:

netstat -s -e --raw | grep -A 5 IpExt
IpExt:
    InBcastPkts: 2422210
    InOctets: -111824737
    OutOctets: -1002951663
    InBcastOctets: 1366977025

This is due to the printval function taking an 'int' and thus truncating larger values

It is also solved in more recent version of netstat / net-tools, for example the git version. See below.

So why not upgrade to a more recent net-tools in Ubuntu? Can the maintainers take care of that?

Git-version:

In Ubuntu's version of netstat, there is the 31-bit overflow error:
