Why isn't it possible to lower TCP values of running SSH session?
...00, 75, 9. After unplugging a network cable I wasn't disconnected within 3 seconds. It made me think that it's possible to modify TCP timeouts of opened TCP sockets such as SSH connections. However, after connecting to the same machine again I changed timeout values 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>
