Hi; I use NFSv4 and have problems with some programms accessing the V4 shares. The symthom is that those apps simply hang on write. Configuration: 2.6.11-1.14_FC3smp (client + server) server services : nfs rpcidmap nfslock client : rpcidmap mnt options : async,auto,exec,_netdev,nodev,rw,retry=5,rsize=32768,wsize=32768,proto=tcp,soft,intr using vi on a file on the share ends in hanging vi. same with other apps including ar etc. Since i need to use v4 (tunnel everthing through one port) - going back to v3 is no option 4 me. Any ideas what could be wrong? any workaround (s) ??? Thx in advance; -- Holger Burde Consulting *IT-Sicherheit & Opensource Consulting* Dipl. Inf.
