Here my experiences with that Interactive UNIX product and a summary of the list's replies to my query: The installation of the product does not work as described. The tcp/ip layer is unuseable: as was said in a network reply, I tried the following: two pings in the background to an unreachable destination. then: telnet localhost Total block during login: sequence. No means to get the thing run again by the keyboard. Thanks a lot for the replies! It saved me a lot of resources that would have been invested in an unsuitable product. michael --------------------follow replies from list --------------------- Hello Michael ! In comp.protocols.tcp-ip you write: >question: does anybody have experiences with the following >TCP/IP side of product: > Interactive UNIX for 368 PCs (and 468), >by Danet? Just a few words: the TCP/IP that comes with ISC 2.2 seems to be fairly well, BUT: - sometimes closed or aborted TCP/IP connections remain in CLOSED state and never vanish completly (a reboot is necessary, to clear things up). - a '/etc/ping' done from the consol or some vt?? can lock up the complete TCP/IP driver. I.e. not more connections possible, neither out of the machine nor into the machine. A reboot is neccessary then. - NFS is not very usable (at least for me). I did some test with a Sun4c as the NFS-server (i.e. mounted filesystem from the sun at the PC-386). The performance is VERY BAD, I measured around 30 KB/sec on an 25 MHz '386. NFS tends to lockup when used heavly (I tested with more then 5 simultanious copies from the NFS mounted filesystem) although the locks vanish after some time. After all: TCP/IP is usable. It highly depends on the usage. It seems not to be 100 % error free, so expect quirks when used heavy.

The only real interoperability problem I've seen is that the telnet daemon in TCP/IP 1.2 doesn't negotiate the X-DISPLAY-LOCATION option correctly. It can be disabled and things work (disable is documented in the telnetd man page). Since nearly all the code originated with 4.3 and 4.3-Tahoe, there shouldn't be too many problems but we would like to know if you hear of any.
