Onderwerp: Re: Netstat -i 5-character interface name length?
Is there a reason (avoid bikeshedding) the field width can't be
increased to allow the bgeXhexIsVeryLong0 names to work?
I agree. I hope POLA is more leaning towards "why does netstat not
print the interface name correctly?" than "my 15 year old script
parsing the output of netstat doesn't understand strings longer than
5 chars".

So all "default" interface names do not fit. I don't like the
solution of "rename all your interfaces" as I think the
out-of-the-box experience can be made better.
I'll vote for enabling -W by default and add an option for backwards
compatibility.
-W makes the address field unnecessarily wide for most users, at least
if IPv6 is enabled. However, netstat already has code to figure out
the required field width to avoid truncating names, which it uses only
for -W. I’d suggest that this should be done unconditionally, as
the
output makes no sense if names are ambiguous. This is a trivial
change
(I just tested it). Any comments or objections? I’ll put it in
review.
It’s https://reviews.freebsd.org/D35703.

walking into a world which is where Linux is, with every physical
device called eth0/1/2 and then "which" device is eth0 becomes a
question..
