Hi, I just thought I'd mention a few hints I picked up recently while compiling Samba for ptx recently for a client: FLAGSM = -DSEQUENT_PTX4 -DSHADOW_PWD -DHAVE_TIMEZONE not -DSEQUENT -DPTX4 as in the Makefile. Get hold of the latest version of TCP (v4.2.1 is supposed to be OK for both ptx4.1.x and 4.2.x), since it includes BSD sockets which were about three times faster than the old ABI sockets (in a very simple test we ran) make sure you are compiling with the BSD sockets, by setting _SEQUENT_CC_ thus: $ _SEQUENT_CC_=-Wc,+bsd-socket $ export _SEQUENT_CC_ Cheers, Phil.
