I have not solved the problem yet, but I think this should be noted (and=20 hopefully fixed :-) by the security officer because with the default config= =20 it installed/created it can be used to create a DOS with a normal user=20 access. My user PPP, even if I tried to reduce the number of connections, add=20 options NMBCLUSTERS=3D16384=20 to my kernel continues to fails after a period depending on the number of=20 connections and the file shared you have ... Any idea/tips ? =2D-=20 Best Regards, Gianmarco Giovannelli , =A0"Unix expert since yesterday" http://www.gufi.org/~gmarco
