what username are you trying to write as? root ? by default nfs blocks root access. if you need root access change exports to something like: /pub M1(rw,no_root_squash) otherwise be sure the userid(the number not the name) on the machine M1 has a directory that is writable by them. if you have user lance(uid=500) on the server and userid lance(uid=1005) on the client it probably won't work. i also usually restart the nfs services after changing the exports file. good luck. nate
