SSH Secure Shell is a encrypted network protocol for initiating text-based shell sessions on remote machines in a secure way.

SSH Host SSH IP/hostname

Payload Keyword
Assuming that 188.100.100.123 is our SSH Server IP and 22 is our SSH port


Keyword Auto Replaced Meaning

[host] 188.100.100.123 Destination host

[port] 22 Destination port

[host_port] 188.100.100.123:22 Destination host and port, seperated by colon:

[ssh] 188.100.100.123:22 SSH server ip and port that you set at settings

[protocol] HTTP\1.0 or HTTP\1.1 HTTP protocol version

[netData] CONNECT [host_port] [protocol] Short form of three keywords

[cr] \r Carriage Return, U+000D

[lf] \n Line Feed, U+000A

[crlf] \r\n CR (U+000D) followed by LF (U+000A)

[lfcr] \n\r LF (U+000A) followed by CR (U+000D)

[crlf][crlf] \r\n\r\n To indicate the end of HTTP header

----------------------------------------------------------------------------------------------------

Troubleshoot
  • 302 Error code - If you are getting 302 HTTP header code that means your ISP is redirecting your request to their captive portal page. Normally ISP blacklisted your remote proxy or the HTTP Payload
  • 400 Error code - This indicate that your payload is invalid and can't be understand by remote proxy
  • Connection timeout - It could be that your network connection is slow or the remote proxy is slow
