[Bug 511401] Re: netstat doesn't display ipv6 addresses correctly (they are truncated)

 

I think this bug can be closed, recent netstat versions have the -W (or
--wide) option to show the full adresses.

To restore tabulation alignment, a wrapper can be used:

netstat -tunap --wide | \
      sed -e '1d' -e '2s/ \(Address\)/_\1/g' -e '2s/\(Program\) /\1_/' -e 's/\([^0-9]*:\) /\1/' -e '/^udp/s/:\*/:\* -/' | \
      column -t


Also, "ss" could be used instead of netstat, ss does not truncate the addresses.

Title:
  netstat doesn't display ipv6 addresses correctly (they are truncated)

Status in net-tools package in Ubuntu:
  Fix Released
Status in net-tools package in Debian:
  Fix Released

Bug description:
  I just installed miredo and begun to use ipv6. I've noticed that
  netstat is incapable to display correctly the sockets when it is
  instructed to display the ipv6 address instead of the name, thus
  making it useless.

  the command issued is
    netstat -n --tcp
  the result is something similar to:

  Active Internet connections (senza server)
  Proto Recv-Q Send-Q Local Address           Foreign Address         State      
  tcp6       0     48 2001:xxxx:yyyy:324:22222 2001:0:zzzz:64c:3:55249 ESTABLISHED
  tcp6       0      0 2001:xxxx:yyyy:324::2:80 2001:0:zzzz:64c:3:51862 TIME_WAIT  


  (please note that xxxx  yyyy zzzz masks real part of the ipv6 address
  because of privacy)

  the result shown by netstat is incomplete, because the ipv6 addresses are truncated in half thus making the netstat command completely useless (I cannot understand who's connecting or whom I'm connecting with).
  enlarging the terminal doesn't help.
  the question:

  is it a bug? is there something I can do?
  thanks a lot
