我使用ssh [email protected] -p 1234 -D 9898命令进行隧道ssh [email protected] -p 1234 -D 9898 ，我将firefox socks5 ip设置为127.0.0.1，将其端口设置为9898.它工作正常，但是在terminal中输出错误：
channel 39: open failed: connect failed: Connection timed out channel 41: open failed: connect failed: Connection timed out channel 42: open failed: connect failed: Connection timed out channel 43: open failed: connect failed: Connection timed out channel 44: open failed: connect failed: Connection timed out
这是定期发生的。 这是什么？ 这是个问题吗？ 我能做什么？
我遇到过类似的问题。 如果您通过ssh使用Firefox进行隧道传输，某些http连接可能会由于服务器负载或configuration不当而超时。 当连接实际上超时，你会得到一个错误信息，如你所指出的。
您可以使用以下命令来禁止这些消息
ssh [email protected] -p 1234 -D 9898 -q
从手册页ssh(1)
-q Quiet mode. Causes most warning and diagnostic messages to be sup- pressed.
抑制消息将保持警告不会搞乱你的SSH或屏幕会话。
将GatewayPorts设置为yes然后重试。
ssh -o 'GatewayPorts yes' [email protected] -p 1234 -D 9898
man ssh_config
DynamicForward Specifies that a TCP port on the local machine be forwarded over the secure channel, and the application protocol is then used to determine where to connect to from the remote machine. The argument must be [bind_address:]port. IPv6 addresses can be specified by enclosing addresses in square brackets. By default, the local port is bound in accordance with the GatewayPorts setting. However, an explicit bind_address may be used to bind the connection to a specific address. The bind_address of “localhost” indicates that the listening port be bound for local use only, while an empty address or '*' indicates that the port should be available from all interfaces. Currently the SOCKS4 and SOCKS5 protocols are supported, and ssh(1) will act as a SOCKS server. Multiple for‐ wardings may be specified, and additional forwardings can be given on the command line. Only the superuser can forward privileged ports. GatewayPorts Specifies whether remote hosts are allowed to connect to local forwarded ports. By default, ssh(1) binds local port forwardings to the loopback address. This prevents other remote hosts from connecting to forwarded ports. GatewayPorts can be used to specify that ssh should bind local port forwardings to the wildcard address, thus allowing remote hosts to connect to forwarded ports. The argument must be “yes” or “no”. The default is “no”.
