pkg-get fails with Invalid PORT
pkg-get (version 3.7.2) reports:
Connecting to ftp.ibiblio.org:21... connected!
Logging in as anonymous ... Logged in!
==> TYPE I ... done. ==> CWD pub/packages/solaris/csw/unstable/sparc/
5.10 ... done.
==> PORT ...
Invalid PORT.
Giving up.
There are multiple repetitions of this exchange. I am behind an
ipfilter firewall, but normal ftp's, wget's, and the like all work.
Anyone have ideas?
