Hello


SOCKS is an Internet protocol that facilitates the routing of network packets between client-server applications via a proxy server. SOCKS performs at Layer 5 of the OSI model - the Session Layer (an intermediate layer between the presentation layer and the transport layer).

Clients behind a firewall may connect to a SOCKS proxy server in order to access external services through the firewall. Such a proxy server controls the eligibility of the client to access the external server and, if the client has eligibility, passes the request on to the server. SOCKS can also be used in the opposite way, allowing the clients outside the firewall ("exterior clients") to connect to servers inside the firewall (internal servers).

SOCKS software

* Kernel SOCKS Bouncer ksb26 (Kernel Socks Bouncer) is a Linux Kernel 2.6.x Loadable Kernel Module that redirects TCP connection (to user-defined target hosts) through socks 4/5 chains.
* SS5 Socks Server is an open-source SOCKS4/SOCKS5 server.
* Dante is an open-source SOCKS4/SOCKS5 implementation with commercial support developed by Inferno Nettverk A/S.
* OpenSSH allows dynamic creation of tunnels, specified via a subset of the SOCKS protocol, supporting the CONNECT command.
* WinSocks is a light-weight SOCKS4/SOCKS5 server developed by Proxy Labs.
* SOcat Multipurpose relay (SOcket CAT): includes socks4, and socks4a functionality (Linux / Mac)
* FreeCap Socksifyer for Windows, any App can run its network traffic transparently via a SOCKS or HTTP proxy.
* Simple Socks Server for Perl - SSS is a Simple SOCKS Server written in perl that implements the SOCKS v5 protocol.
* Sun Java System Web Proxy Server is a caching proxy server running on Solaris, Linux and Windows servers that supports HTtp://S, NSAPI I/O filters, dynamic reconfiguration, SOCKSv5 and reverse proxy.
* BarracudaDrive Web Server - commercial SOCKS HTTP HTTPS tunnel/server, available for Windows, embedded Linux and Mac OS X (PowerPC)
* DeleGate is a multi-purpose application level gateway and proxy server which runs on multiple platforms. Beside SOCKS it also supports HTTP(S), FTP, NNTP, SMTP, POP, IMAP, LDAP, Telnet, DNS and many more.

MSACCESS Multi user APplication


Access is never good for multi-user with more than about 10 users! MS say: use SQL server. Of course, it all depends on the complexity of the app, the amount of data, transaction rate etc. You can also try putting the backend on a "real" server (15K rpm SCSI or sSCSI disc, Xeon CPU) and give it as much RAM as you can afford (at least 4GB) then you might get reasonable performance. If you can't do it any other way & a licence for MS SQL Server is out of the question, use MySQL as a backend: you can make Access clients talk to it as there is a free Access driver for it. You can even run MySQL under windows: you don't need Linux (although it will run faster under Linux). Setting it up is fairly easy and it will outperform an Access backend by at least an order of magnitude, if not 2 or 3 :)
