Hi,
I've just noticed that cvsup flags in my RELENG_6 Makefile.inc1 are still:
SUPFLAGS?= -g -L 2 -P -
But, from man CVSUP(1):
-P m|a|port|lo-hi|-
Controls the establishment of the auxiliary TCP connection(s)
used to carry information between the client and the server.
Altogether, the client and server require four unidirectional
channels to communicate: two from the client to the server,
and two from the server to the client. These four unidirec-
tional channels can be set up in different ways, to support
various firewall setups. The modes provided for this are
multiplexed mode, passive mode, and active mode. All but
^^^^^^^
multiplexed mode are deprecated. Multiplexed mode can handle
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
any situation that the other modes can handle.
This means that if I don't specify any overrides in /etc/make.conf or my
supfile, running 'make update' in /usr/src will cause cvsup to try to use
passive mode and, in my firewalled environment, fail. Yep, I found this
out by accident :)
regards,
