There are a number of possibilities for mixing TCP/IP and SNA networks. The ones I have come across are: o- Use a TCP/IP telnet to SNA 3274 gateway convertor. This looks like a telnet host on Ethernet to UNIX systems, and looks like a 3274 terminal controller (either remote or channel attached) to the IBM mainframe. Products which provide this are available from Mietek or software from SUN. o- Add TCP/IP software to the Mainframe host and use that as a gateway between UNIX and SNA users. Software and hardware available from Fibronics, ACC, even IBM. o- To use an existing SNA network to link together a number of remote TCP/IP networks requires something like the SNA/IP gateway available from Brixton Systems. This is a HW/SW package that plugs into a VME based SUN. It uses IP routing SW to route the packets across the SNA network, by emulating an IBM Front End Processor. o- Use a UNIX host which can also provide a very high degree of SNA interoperability. ------------------------------------------------------------------------- Richard Croucher {ames,sun,uunet,decwrl}!amdahl!rcc30 UNIX Consultant +44 252 346376 UNIX Systems, Europe "any views, expressed or implied are not necessarily those of my employer" -------------------------------------------------------------------------
