Exactly the same system configuration and exactly the same problem - except that we have a 780. Timeout occurs during both "put" and "get". When transferring large text or binary files from the PC to the Vax, timeout occurs consistently after 10K bytes - and it takes 150 (+- 3) seconds to do the transfer. Smaller files get transferred quite easily. I have played around with all sorts of tftp parameters on the PC and nothing seems to affect the results. On the Vax, I don't see any configuration file anywhere - all configuration parameters seem to be compiled it. Does anybody out there know what should be changed ? We also have an Alliant machine - and using the same tftp ( same as that on the vax, but recompiled for the Alliant ), I can tranfer the large files from the PC to the Alliant BUT not back to the PC. "get" works but "put" times out. Does anybody have any clue to what the problem is ? Madhu Sharma Univ. of Illinois at Urbana-Champaign ..!ihnp4!uiucdcs!uicsrd!sharma or sharma@uicsrd.csrd.uiuc.EDU

Does anybody out there >know what should be changed? The whole thing. The 4.2BSD tftp was largely broken. Borrow the 4.3BSD version. The 4.2 tftp manual page, under BUGS, mentions Due to the unreliability of the transport protocol (UDP) and the scarcity of TFTP implementations, it is uncertain whether it really works. What this really means is We got our tftp to talk to itself, but we had no idea where to find another one to talk to, so we doubt that it really works. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7690) UUCP: seismo!mimsy!chris ARPA/CSNet: chris@mimsy.umd.edu
