I have serverA with a rhel 6 flavor with no connection to internet and serverB with Win Server and Cygwin that connects to internet through a proxy namely I can do something like wget http://google.com and get a response. I was looking for a way to redirect the internet connection with SSH and found this posts 1, 2, 3; particularly I'm trying to use ssh -D 1080 user@serverB & from serverA.
The ssh connection is stablished with no problems but when I try to issue curl --socks5-hostname 127.0.0.1 http://google.com from serverA I get the following error curl: (7) Failed to receive SOCKS5 connect request ack and in serverB channel 3: open failed: administratively prohibited: open failed. I searched for the second error which seemed more promising and found 4, 5, 6. I checked and doubled checked that sshd_config had the appropiate configs and restarted cygwin sshd but the same errors appear when I try to reach any page. Here is my sshd_config:
$ grep -Ev '^(#.*|\s*)$' /etc/sshd_config
Port 22
StrictModes no
AuthorizedKeysFile .ssh/authorized_keys
AllowTcpForwarding yes
PermitOpen any
PermitTunnel yes
X11Forwarding yes
PermitTTY yes
TCPKeepAlive yes
UsePrivilegeSeparation sandbox # Default for new installations.
PermitTunnel yes
Am I missing any other config I should do in cygwin or windows? Is this even possible to be done with cygwin or I misread some of the threads I referenced?
Thank you
