Oh, for the first question, I run fedora core 4 at home and the netcat
program I installed can act as a socks client. Here is the nc -h output:
nc -h
usage: nc [-46DdhklnrStUuvz] [-i interval] [-p source_port]
[-s source_ip_address] [-w timeout] [-X proxy_version]
[-x proxy_address[:port]] [hostname] [port[s]]
Command Summary:
-4 Use IPv4
-6 Use IPv6
-D Enable the debug socket option
-d Detach from stdin
-h This help text
-i secs Delay interval for lines sent, ports scanned
-k Keep inbound sockets open for multiple
connects
-l Listen mode, for inbound connects
-n Suppress name/port resolutions
-p port Specify local port for remote connects
-r Randomize remote ports
-S Enable the TCP MD5 signature option
-s addr Local source address
-t Answer TELNET negotiation
-U Use UNIX domain socket
-u UDP mode
-v Verbose
-w secs Timeout for connects and final net reads
-X proto Proxy protocol: "4", "5" (SOCKS) or
"connect"
-x addr[:port] Specify proxy address and port
-z Zero-I/O mode [used for scanning]
Port numbers can be individual or ranges: lo-hi [inclusive]
You can see the -X and -x options. Here is the version info

Summary : Reads and writes data across network connections using TCP or
UDP.
Description :
The nc package contains Netcat (the program is actually nc), a simple
utility for reading and writing data across network connections, using
the TCP or UDP protocols. Netcat is intended to be a reliable back-end
tool which can be used directly or driven by other programs and
scripts. Netcat is also a feature-rich network debugging and
exploration tool, since it can create many different connections and
I have been using it as a socks client on my fedora box for a long time.
Perhaps this is specific to fedora/redhat?
