Hi all, I used a program to dial from one system to another system, but it gives a connection time out error. I have searched on Internet for a long time and cannot get a solution. Could you please provide some suggestions or hints? Basically, one system is Linux based system with rc shell installed (we call it A). The other one is a auth+cpu+file server (we call it B). On B, I have used fossil/conf command to listen tcp!*!564. On A, I executed dial tcp!!564, but it reports a time out error after waiting some time. Results are the same when A is a plan9 terminal. By the way, I can ping A to B successfully. What could be the possible problems? Thanks, Yan -- Think big; Dream impossible; Make it happen.
