Hi, I've got some machines running as NIS clients very fine. Files like hosts, networks, auto.master, ... are used by all these machines. The passwd-file is also allocated by NIS and I can change the passwd by yppasswd an some minutes later I have the new password on all other machines. Everything is fine, but there is one thing I cannot change and maybe it's just a small entry in one configuration-file. The NIS server should be a NIS client at the same time so that I can logon to my NIS server by using the same password as I use for the NIS clients. I configured all files in the same way as I configured the other client machines but when I log on the server I have to give the password I gave the server when I installed the linux system. Using passwd (or yppasswd) on the server will change the NIS password so that I have to login on every nis client with the new apssword except the server/client. I don't see any possibility to change this password (or to login to server using the same password I am using for the clients). One more thing attract my attention: In the nsswitch.conf file the order to lookup for the passwd is 'nis files'. I can login my server by using the 'local' passwd (not the nis passwd). If I delete the 'files' entry, so that all passwds should be talken from nis it makes no differences. But, I am not able to change to root any longer (whcih seems to be normal). Maybe someone can help me ? Or do you have a good link to get a solution for this ? Thanks, ... ...niels. Here are some of my configurations: Using SuSE 8.2 on alle machines. The 'domainname' is the same on all machines. /etc/nsswitch.conf (on all machines): passwd: nis files shadow: nis files group: nis files hosts: nis [NOTFOUND=return] files networks: nis [NOTFOUND=return] files ... yp.conf contains the IP of the server or 127.0.0.1 (on all machines) /var/yp/securenets allows access for 255.0.0.0 127.0.0.0 255.255.255.224 192.168.200.0 /etc/passwd contains no 'normal users'. The last line is +:::::: (same for file /etc/group) /etc/nis/passwd contains all 'normal users' and /var/yp/Makefile includes /etc/nis for passwd, shadow and groups. -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln!

Maybe this helps to find a solution for my problem ? I started the NIS server with the -d option and looked at the messages. It seems to me that there is a problem with the 'gdbm tool' ? I hope by shortening the logs I didn't loose some important informations. Does anyone has an idea about this ? Another question: Why does the client tries to get the shadow-map? I told the NIS server to merge the passwd and the shadow file - so, there is no shadow map which the client could get.
