[gentoo-user] iftop and 'ipv6' USE-flag

[gentoo-user] iftop and 'ipv6' USE-flag

[v_2e]

  Hello!
  During a recent upgrade, I noticed that 'net-analyzer/iftop'  now
needs 'net-libs/libpcap' with the 'ipv6' USE flag. It seemed strange to
me and I decided to ask here. Does 'iftop' really needs IPv6? Can't it
be optional?

  Thank you.

It's an upstream bug, if they consider it one. From the Gentoo ChangeLog:

  30 May 2012; Lars Wendler <polynomial-c@gentoo.org> iftop-
  1.0_pre2.ebuild:
  Non-maintainer commit: We need libpcap with ipv6 support or else iftop
  doesn't work at all.

I downloaded the latest iftop tarball and,

  1  There is no ./configure option for ipv6

  2  Compiling it against libpcap without ipv6 support works, but it
     crashes at runtime:

       $ sudo ./iftop
       ...
       set_filter_code: ip6 not supported

  Hm... That's bad.

Agreed. I reported it upstream and opened a bug:
