SunOS alpha 5.5 Generic_103093-03 sun4c sparc SUNW,Sun_4_40 Good time of day, ppl. There is a very strange behaviour of kernel sockets interface in Solaris 2.5. I am running TCP gateway on this platform and there is a funny situation: when gatewaying telnet connection thru this system there is a random garbage data that is coming from communication channel if I use TELNET-ESCAPE character to close session. As far as I can explain this - it happens when tcp-gateis trying to read something from socket that is being closing from remote peer. For example, there is a description of something that really happens: Host A (HP-UX) -> tcp-proxy Host B (Solaris) -> Destination Host C (FBSD) tcp-proxy is simple - it opens second TCP connection and then transfers data between first and second till one of them signals that connection is broken or closed. This channel is a local peer between two ISP and mostly HTTP traffic passes thru. So, when I close telnet on host A just by typing ^], then reconnect - I see a lot of HTTP headers as it was typed on console after I have closed connection. Seems to be a very interesting situation, because in most cases TCP sessions should not be available in any case for others but owner. Wish you all the best, Natali.
