I've been happy with the Dante socks implementation, which built
easily on NetBSD and has "just worked" for me for ftp, cvs, ssh
etc.

Dante is available in pkgsrc as net/dante and it's homepage is
http://www.inet.no/dante/.   It includes a "socksify" script
that I didn't have to modify.

Sounds like a configuration problem.  I've not used the NEC socks
distribution so I don't know how to configure it.  One of the nicer
things about the Dante implementation is the configuration file is
sane:

...
#
# All local networks should be direct: loopback
#
route {
	from: 0.0.0.0/0   to: 127.0.0.0/8  via: direct
	command: connect udpassociate # everything but bind, bind confuses us.
}
...
route {
        # yes, IP address below is edited prior to posting :(
	from: 0.0.0.0/0 to: XXX.XXX.X.XXX/25 via: host.example.com port = 1080
	protocol: tcp udp
	proxyprotocol: socks_v4 socks_v5
	method: none
}
...

Good luck,

Giles
