Linux (mine: 1.2.13) allows up to 128 connections, including http connections, but some browsers (e.g. Netscape) usually limits this number. by default - 4 connections.

To change limit of Linux connections up to 256 (maximal opened files), you have to increase NSOCKETS_UNIX in file /usr/include/linux/net.h; and if you wanna increase it more, you need change NR_OPEN in file /usr/include/linux/limits.h.

don't forget to rebuild kernel after that

and if you wanna to change tcp connections in Netscape navigator, you have to change field "connections" in Options->Networkpreferences->Connections
