Re: sshfs does not seem to work correctly
Again I am guessing, but OpenBSD might disconnect if there is a sufficient period of inactivity on the sshfs file system. Usb drives disconnect if left long enough, for example. A running process, such as an open terminal on the usb prevents this. It is a security feature. There had only be seconds (at least one or two minutes) of inactivity. Can this feature be disabled? I'd like to use sshfs just as nfs so it should not disconnect if possible. A ssh session does not disconnect too, I see no difference between ssh and sshfs regarding security here. Carsten

Carsten I've never used sshfs on OpenBSD yet, but there is a -o reconnect option in it on linux. I've used sshfs to move even larger datasets than 15GB with no problems. But you might want to tune it with by playing with the cache, compression, ciphers, etc options so it will give you better performance.
