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.
