We have several DECstation 3100s hooked together on an ethernet. The connection is quite speedy. When one is logged into one 3100 (via an xterm), and runs an rlogin into another machine, frequently whole bunches of characters of output never make it to the screen. This problem also occurs when we rlogin to our ancient VAX (running BSD 4.3). The problem is fairly nondeterministic - I can be rlogged into another machine, type ls in the same directory 4 times, and 1 time I will get the complete output, 2 times one batch of characters will be missing, and the last time some other batch of characters will be missing. The problem occurs equally under bash and Ultrix-supplied csh. Needless to say, it makes rlogin difficult. For example, rlogging into another DS3100 and typing ls thrice in a row will generate output like: (first line only) altosax/ dharma/ lost+found/ projects/ u/ vishnu/ rma/ lost+found/ projects/ u/ vishnu/ altosax/ dharma/ lost+found/ projects/ u/ vishnu/ These are supposed to be the same! We can, however, run xterms through an rsh to another machine. In this case all characters make it through all the time. Is this behaviour a 'feature' of Ultrix 4.1 rlogin? It wasn't as bad when we were running Ultrix 2.2, but its bad enough now that rlogin is unusable. Does rlogin not guarantee that all characters get from the other machine to you?
