OK, a lot of people will tell me now that this is terribly bad/insecure/
hacked/false/... (pick what you want), but this is what I do:
/var/spool/pcnfs -network 192.168.1.0
and the following patch to mountd.c (compile with -DANDRE, of course):
*** mountd.c.ORI Wed May 12 09:08:11 1999
--- mountd.c Wed May 12 11:13:31 1999
***************
*** 1230,1236 ****
--- 1230,1240 ----
int cmp;
if (dp) {
+ #ifdef ANDRE
+ cmp = strncmp(dp->dp_dirp, dirpath, strlen(dp->dp_dirp));
+ #else
cmp = strcmp(dp->dp_dirp, dirpath);
+ #endif
if (cmp > 0)
return (dirp_search(dp->dp_left, dirpath));
else if (cmp < 0)
This implies -alldirs for every line in /etc/exports and this even if it
isn't the root of a filesystem. It worked well for years now here...
