bridging ethernets containing vlans,

2006-12-21 Thread Julian Elischer

Non-accessible NFS share via SMB and NFS lag

2006-12-21 Thread Garrett Cooper
Hello, I am having an issue with NFS and SMB on two FreeBSD machines. The particularly strange thing is that this problem didn't occur when I ran Gentoo Linux on PC_2. Setup: 1. PC_1 and PC_2 share with each other via NFS. 2. Both PCs run patched versions of FreeBSD 6.1 RELEASE (see below)
