Hallo list, is anyone using a netgroup NIS map in /etc/exports? I tried on nfssrv: --- cat netgroup nfshosts (locomo.domain.de,,) --- cat exports /san/shares/nfs.d @nfshosts(rw,sync,insecure) Then host locomo ist not allowed to mount nfssrv:/san/shares/nfs.d with this line in /var/log/messages: rpc.mountd: refused mount request from locomo.domain.de for /san/shares/nfs.d (/): not exported A "showmount -e nfssrv" gives /san/shares/nfs.d @dnfshosts If I use the hostname instead of the netgroup in /etc/exports: --- cat exports /san/shares/nfs.d locomo.domain.de(rw,sync,insecure) locomo is allowed to mount nfs.d . Both server and client are in the same DNS domain and in the same NIS domain, DNS is working fine forward and reverse. The "hosts" line in /etc/nsswitch.conf reads on both hosts: files dns Does anybody have an idea what may be wrong? -- Viele Grüße ------------------------------------------------------------------------ Michael Behrens Technical Support PROSTEP AG Dolivostraße 11, D-64293 Darmstadt Tel: +49 (0)6151 9287 335 Fax: +49 (0)6151 9287 326 mailto:Michael.Behrens@prostep.com http://www.prostep.com ------------------------------------------------------------------------
