Q33.   What is a single-homed and multi-homed firewall?                 
A33.

  A multi-homed firewall has multiple network interfaces and does not forward packets. Single-homed firewalls have one 

network interface card.  You would use a single-homed firewall with a choke router that filters packets not originating 
from the SOCKS server.  

 

Q34.   Is there an RFC for SOCKS? 
A34.

   There is no official RFC for Version 4 of the protocol. There are two documents describing Version 4: SOCKS V4 

protocol and extension to SOCKS V4 protocol. There are three RFCs for SOCKS V5 related protocols:  
RFC1928 - Describes SOCKS Version 5 protocol, also known as Authenticated Firewall Traversal (AFT).  
RFC1929 - Describes Username/Password authentication for SOCKS V5.  
RFC1961 - Describes GSS-API authentication for SOCKS V5  

 

Q35. Why does the password echo when I run RFTP? 
A35.

  The password only echoes for anonymous ftp. This is considered a feature.  

 

Q36.   What causes the log message 

incompatible version number: 71

?        

A36.

  Socks displays this log message when someone tries to use the SOCKS server as an HTTP proxy. ASCII code 71 is 

the letter "G", the first letter of an HTTP/1.0 request.
