[EMAIL PROTECTED]:/var/www/01-gas/fmb.no/gas $ apt-cache --full show pcproxy Package: pcproxy Priority: optional Section: games Installed-Size: 196 Maintainer: Kees Leune <[EMAIL PROTECTED]> Architecture: all Version: 1.1.1-2 Depends: tk8.0 | tk8.2 | tk8.3 | tk8.4 Filename: pool/main/p/pcproxy/pcproxy_1.1.1-2_all.deb Size: 38294 MD5sum: 8d02f7c3a9d11db4938697f32e3c0239 Description: A masquerading proxy for flight simulation networks PCProxy allows multiple flight simulation clients to share a single network connection to a flight simulation network, such as VATSIM or IVAO, which is based on the fsd (Flight Simulator Daemon) protocol. This is particulary useful for players who wish to have multiple network clients active at the same time. In tech-terms, PCProxy is a multi-connect masquerading proxy for fsd traffic over TCP/IP. . PCProxy currently only supports networks which operate using the fsd protocol, like VATSIM and IVAO.
