- I seem to have a stable (connection stays up, system doesn't crash) ppp
- running which inter-operates with my SRARC2 running dp2.0.2. The biggest
- problem has been the good old "silo overflows". The only way I could
- get the problem to go away was installing the 16550 UART chip. Without
- it, TCP/IP would would lock up or perform so poorly as to be unusable.
-
- I still have problems with pppd and select. PPPD gets a signal to
- inform him a packet is available, but select returns ZERO
- (intermittent). I simply kludged around it by issuing a message and
- doing the read anyway. The code will abort if nothing is returned on
- the read, but so far this hasn't happened.
-
- The only "show stopping" problem so far is in my kernel (generic TCP/IP bogon).
- (I seem to have shot myself in the foot with some patch somewhere since I
- haven't heard anyone else complain.)
- Things like FTPD and NAMED are failing with EACCES trying to BIND
- privileged ports (Port 20 in the case of ftpd). Any ideas?
- I've been poking around down in so_bind trying to figure out who's setting
- errno and it looks like it might be namei.
-
- The hacks are available on sunvis.rtpnc.epa.gov:~/pub/386bsd/ppp-hacks
- See the READ.THIS and the READ* files in the tar file.
-
- Also an archive of "culled" news is there in:~/pub/386bsd/culled.news
-
- Caution, this is a snapshot of work in progress and should be
- considered alpha--. I'm posting this because I've had requests and
- could use a little help with the bind problem.
