我正在尝试通过HTTP代理建立ssh隧道。
当使用鱿鱼本地代理测试安装程序时，我从(我想)Apache远程代理收到“不允许的方法”:
$ proxytunnel -v -p localhost:3128 -r torno.example.com:80 -d ssh.example.com:22 -H "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)\nHost: ssh.example.com\nContent-Length: 0\nPragma: no-cache"
Local proxy localhost resolves to 127.0.0.1
Connected to localhost:3128 (local proxy)
Tunneling to torno.example.com:80 (remote proxy)
Communication with local proxy:
-> CONNECT torno.example.com:80 HTTP/1.0
-> Proxy-Connection: Keep-Alive
-> User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)\nHost: ssh.example.com\nContent-Length: 0\nPragma: no-cache
<- HTTP/1.0 200 Connection established
Tunneling to ssh.example.com:22 (destination)
Communication with remote proxy:
-> CONNECT ssh.example.com:22 HTTP/1.0
-> Proxy-Connection: Keep-Alive
-> User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)\nHost: ssh.example.com\nContent-Length: 0\nPragma: no-cache
<- HTTP/1.1 405 Method Not Allowed
HTTP return code: 405 Method Not Allowed
<- Date: Thu, 25 Aug 2011 17:17:07 GMT

<- Allow: GET,HEAD,POST,OPTIONS,TRACE
<- Content-Length: 352
<- Connection: close
<- Content-Type: text/html; charset=iso-8859-1
这是我的Apache虚拟主机配置:
<VirtualHost *:80>
ServerAdmin admin@example.com
ServerName torno.example.com
ServerSignature Off
HostnameLookups Off
LogLevel Warn
ErrorLog logs/torno.example.com-error_log
CustomLog logs/torno.example.com-access_log combined
ProxyRequests On
AllowConnect 22
<Proxy *>
Order deny,allow
Deny from all
</Proxy>
<Proxy ssh.example.com>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://www.ibm.com/
ProxyPassReverse / http://www.ibm.com/
<Proxy http://www.ibm.com/>
Order deny,allow
Allow from all
</Proxy>
</VirtualHost>
有任何想法吗？如何读取405响应的正文以确保它来自远程Apache代理而不是本地squid代理？
编辑:
该请求将进入默认服务器日志:
189.99.135.105 - - [25/Aug/2011:17:17:07 +0000] "CONNECT ssh.example.com:22 HTTP/1.0" 405 352 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)\\nHost: ssh.example.com\\nContent-Length: 0\\nPragma: no-cache"
新的编辑:
将代理虚拟服务器设置为默认服务器可以使其正常工作!
$ proxytunnel -v -p localhost:3128 -r torno.example.com:80 -d ssh.example.com:22 -H "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)\nHost: ssh.example.com\nContent-Length: 0\nPragma: no-cache"

这是怎么回事一些proxytunnel错误？
编辑:
这不是proxytunnel的错。通过远程登录进行连接时会发生相同的情况:
$ telnet torno.example.com 80
Trying 1.2.3.4...
Connected to torno.example.com.
Escape character is '^]'.
CONNECT ssh.example.com:22 HTTP/1.1
Host: ssh.example.com
HTTP/1.1 405 Method Not Allowed

现在将配置文件移动到aaa.torno.example.com.conf以使其成为默认文件，并且可以正常工作:
$ telnet torno.example.com 80
Trying 1.2.3.4...
Connected to torno.example.com.
Escape character is '^]'.
CONNECT ssh.example.com:22 HTTP/1.1
Host: ssh.example.com
HTTP/1.0 200 Connection Established
Proxy-agent: Apache/2.2.15 (CentOS)
SSH-2.0-OpenSSH_5.3
最佳答案
您会在405响应中看到“服务器:Apache / 2.2.15(CentOS)” header ，因此，如果您使用Squid，则响应必须来自服务器。
附带说明一下，我将把这个问题放到ServerFault而不是这里。
