Hi,
I am a Ph.D. student at the University of Karlsruhe, Germany. For a
project on Mobile IPv6, I need a simple tool with which data can be
transmitted over TCP. The problem is: I depend on outdated FreeBSD 4.10.
I guess that Nc6 would give me everything I need. However, when I type
# cd /usr/ports/net/nc6/
# make
on my FreeBSD 4.10 system, I get an error message:

*** Error code 1
Stop in /usr/ports/net/nc6/work/nc6-0.5/src.
*** Error code 1
++++++++++
The two identifiers EAI_NODATA and EAI_ADDRFAMILY appear only one time
in the entire Nc6 code, namely, in a swich statement in file filter.c.
I replaced the identifiers by their values (7 and 1, respectively), and,
guess what, Nc6 compiled successfully.
However, when I use the program for a TCP connection, it aborts with an
error:
# /usr/local/bin/nc6 1000::1 2000
nc6: forward host lookup failed for remote endpoint 1000::1:
Non-recoverable failure in name resolution
At this time, Nc6 is running in listen mode on node 1000::1. (I called
/usr/local/bin/nc6 -l -p 2000 -s 1000::1 on the remote machine.) The
funny thing is that I am providing an IPv6 address above, but Nc6 still
seems to try doing name resolution. This does not change when I use the
"-n" option.
I suppose that the problem is due to the software in the Ports archive
being incompatible with FreeBSD 4.10. Therefore, I wonder if you have
an older version of Nc6 that I could use. As far as the additional
software that Nc6 requires goes, I have the following versions on the
FreeBSD 4.10 system:
expat-1.95.6_1
gettext-0.12.1
libiconv-1.9.1_1
I would be so greatful if you could help me out!
Best regards,
- Christian
