未能實現到新的 ubuntu 10.04 伺服器的隧道
我剛剛設置了一個新的 10.04 伺服器,但無法讓隧道工作。
本地機器
ssh -L 9090:localhost:9090 admin@xxx.xx.xx.xxx
登錄成功,但隨後從本地瀏覽器嘗試隧道,
http://127.0.0.1:9090
在伺服器終端回顯:
channel 3: open failed: connect failed: Connection refused
auth.log
:sshd[24502]: error: connect_to localhost port 9090: failed.
iptables -L
Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination
9090
在伺服器上嘗試(links http://xx.xxx.xx.xx:9090
工作)
sshd_config
與之前的 8.04 伺服器相同,工作正常。這是怎麼回事?
詳細輸出 (-vvv)。
登錄成功。根據本地瀏覽器的隧道請求,在伺服器終端:
ebug1: Connection to port 9090 forwarding to localhost port 9090 requested. debug2: fd 9 setting TCP_NODELAY debug3: fd 9 is O_NONBLOCK debug3: fd 9 is O_NONBLOCK debug1: channel 3: new [direct-tcpip] channel 3: open failed: connect failed: Connection refused debug2: channel 3: zombie debug2: channel 3: garbage collecting debug1: channel 3: free: direct-tcpip: listening port 9090 for localhost port 9090, connect from 127.0.0.1 port 57884, nchannels 4 debug3: channel 3: status: The following connections are open: #2 client-session (t4 r0 i0/0 o0/0 fd 6/7 cfd -1) debug3: channel 3: close_fds r 9 w 9 e -1 c -1
請注意,埠 9090 回复
# links 127.0.0.1:9090
在工作機器上:(8.04)
應要求:
debug1: Connection to port 9090 forwarding to localhost port 9090 requested. debug2: fd 10 setting TCP_NODELAY debug3: fd 10 is O_NONBLOCK debug3: fd 10 is O_NONBLOCK debug1: channel 3: new [direct-tcpip] debug2: channel 3: open confirm rwindow 2097152 rmax 32768 debug2: channel 3: rcvd eof debug2: channel 3: output open -> drain debug2: channel 3: obuf empty debug2: channel 3: close_write debug2: channel 3: output drain -> closed
問候 //t
基於此執行緒,我認為您的問題的原因可能是 Apache,而不是 sshd。
嘗試將 httpd.conf 文件中的 Listen 指令更改為
聽 127.0.0.1:9090
之後重新啟動httpd,看看是否有什麼不同。
