...lues to 3, 1, 1 again. To my surpires, after unplugging a network cable on the remote side I wasn't disconnected within 3 seconds. It seems it's only possible to increase TCP timeout values when SSH session is already opened but not to lower them. Why? Is it Linux or OpenSSH thing? -- <wempwer at gmail.com>

I suggested 4 alternative ways to solve this problem in my first post. I just want to know why can't I do chown as a guest in a mounted directory. -- <wempwer at gmail.com>
