System: NetBSD oink 0.9C NetBSD 0.9C (OINK) #201: Fri Jun 17 05:29:16 MET DST 1994 noses@oink:/usr/src/sys/arch/i386/compile/OINK i386


>Description:

Servers complain that NFS access is tried rith "too weak credentials" and
refuse any request.

>How-To-Repeat:

Mount an NFS volume from another server e.g.:

mount gatekeeper.rhein.de:/home/bnc /home.
Result:
bnc# mount
/dev/sd0a on / (local)
kernfs on /kern (local)
fdesc on /dev/fd
mfs:19 on /tmp (asynchronous, local)
/dev/sd0e on /usr (local)
/dev/sd0f on /usr/local (local)
/dev/sd0g on /var (local)
/dev/sd0h on /var/spool (local)
gatekeeper.rhein.de:/home/bnc on /home
bnc# netstat -f inet
Active Internet connections
Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)
tcp        0      0  bnc.login              oink.rhein.de.1023     ESTABLISHED
tcp        0      0  bnc.login              gatekeeper.rhein.1017  ESTABLISHED
udp        0      0  localhost.ntp          *.*
udp        0      0  bnc.ntp                *.*
udp        0      0  localhost.domain       *.*
udp        0      0  bnc.domain             *.*
udp        0      0  bnc.1028               gatekeeper.rhein.2049

Port 1028 isn't acceptable to the server; at least ALL Sun versions of
NFS dislike this.

>Fix:

Return to the algorithm for selecting a port that was used in 0.9b.
