Ciao, I have look around for the solution of this problem, but untill now I haven't find the "right" solutions (= no more problem :-)
Shortly: etc# id uid=0(root) gid=0(root) gruppi=0(root) etc# ypcat passwd nis01:x:1001:1001:untente nis 01,,,:/home/nis01:/bin/bash nis02:x:1002:1002:utente nis 02,,,:/home/nis02:/bin/bash etc# su nis01 su: Authentication service cannot retrieve authentication info. (Ignored) $ su nis02 Password: su: Authentication service cannot retrieve authentication info. Sorry. etc$ id uid=1001(nis01) gid=1001(nis01) gruppi=1001(nis01) etc$ ypcat passwd nis01:x:1001:1001:untente nis 01,,,:/home/nis01:/bin/bash nis02:x:1002:1002:utente nis 02,,,:/home/nis02:/bin/bash so it seems that nis works (in some way...) etc$ uname -a Linux u7365a 2.4.1 #1 mar feb 6 17:15:49 CET 2001 i686 unknown /etc/apt/sources.list contains "testing" debian dpkg -l nis ii nis 3.8-3 Clients and daemons for he Network Information Services (NIS) dpkg -l portmap ii portmap 5-1 The RPC portmapper etc$ cat /etc/nsswitch.conf # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: files nis group: files nis shadow: files nis hosts: files nis dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis On the server: # rpcinfo -p localhost program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100011 1 udp 794 rquotad 100011 2 udp 794 rquotad 100011 1 tcp 797 rquotad 100011 2 tcp 797 rquotad 100004 2 udp 807 ypserv 100004 1 udp 807 ypserv 100004 2 tcp 810 ypserv 100004 1 tcp 810 ypserv 100009 1 udp 809 yppasswdd 600100069 1 udp 812 600100069 1 tcp 814 100007 2 udp 821 ypbind 100007 1 udp 821 ypbind 100007 2 tcp 825 ypbind 100007 1 tcp 825 ypbind 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100021 1 udp 32780 nlockmgr 100021 3 udp 32780 nlockmgr 100021 4 udp 32780 nlockmgr 100024 1 udp 657 status 100024 1 tcp 659status 100005 1 udp 32795 mountd 100005 1 tcp 46225 mountd 100005 2 udp 32795 mountd 100005 2 tcp 46225 mountd 100005 3 udp 32795 mountd The really strange thing is that with a RH 6.2 server it works all right, but with a Debian 2.2 server it doesen't works. (all clients are deb 2.2) Any hint? TNX -- Paolo Pedaletti, Como, ITALYa www.fastflow.it/~paolop [EMAIL PROTECTED] ICQ: 4755831
