A year ago I tried out NIS and had it working on my Slackware system.
(I didn't actually need to use it, so I only ran it for a day.)
I can't seem to get it to work now. When ypbind is running, commands
that should trigger a name lookup don't even cause the lights on my
modem (ppp) or ISDN box to blink with any activity. Same is true when
I execute ypbind itself: no line activity.
Routing is OK, since I can telnet, ftp, etc to remote hosts by using
IP addresses rather than names.
Running the following commands:
/etc/init.d/nis start
rpcinfo -p localhost
rpcinfo -u localhost ypbind
domainname
ps -auwwx|grep yp
gives this output:
# /etc/init.d/nis start
Setting NIS domainname to: veritas
Starting yellow page services: ypbind
# rpcinfo -p localhost

root 1529 0.0 1.2 832 384 ? S 23:55 0:00 /usr/sbin/ypbind
Is is strange that ypbind appears twice?
Various commands give these error messages:
# ypcat passwd
YPBINDPROC_DOMAIN: No bound server for domain veritas
No such map passwd.byname. Reason: Can't bind to server which serves this
domain
# ping rickm
YPBINDPROC_DOMAIN: No bound server for domain veritas

# ypwhich
can't yp_bind: Reason: RPC failure
I get this message in /var/adm/daemon.log (remember, the lights never
blink on the modem):
Oct 10 00:06:01 localhost /usr/sbin/ypbind[28920]: Running in restricted
mode -- request to bind domain "veritas" rejected.
I have "+::::::" in /etc/passwd and "+:::" in /etc/group.
/etc/host.conf:

multi on
In the file /etc/init.d/nis, I've tried
start-stop-daemon --start --quiet --exec ${NET}/ypbind -- -S
comsrv1,192.159.106.123
and just
start-stop-daemon --start --quiet --exec ${NET}/ypbind
in case there's a problem with broadcasting.
I've installed the latest unstable versions of netbase, netstd and nis:
-rw-rw-rw- 1 root 206560 Sep 1 08:26 netbase_2.06-1.deb
-rw-rw-rw- 1 root 660206 Aug 30 18:27 netstd_2.07-1.deb
-rw-rw-rw- 1 root 90118 Oct 3 06:47 nis_2.00-1.deb
With my ISDN:
# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.49.0 0.0.0.0 255.255.255.0 U 1500 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 3584 0 0 lo
0.0.0.0 192.168.49.1 0.0.0.0 UG 1500 0 0 eth0
With my PPP:
# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.159.106.8 0.0.0.0 255.255.255.255 UH 1500 0 0 ppp0
127.0.0.0 0.0.0.0 255.0.0.0 U 3584 0 0 lo
0.0.0.0 192.159.106.8 0.0.0.0 UG 1500 0 0 ppp0
Note that with ppp, I'm on the same subnet as the NIS server, but with
ISDN I'm on a different one. Both ways, I have this same problem.
The nis server is there:
