Hello- I'm having intermittent problems communicating from PC PC via NCSA Telnet & FTP, v2.3. Any help on the following symptoms would be greatly appreciated. - PC #2 is in Telnet. PC #1 FTP's to #2, logs in, etc. All goes fine until during some sort of transfer (a file transfer, or even a directory transfer), transmission appears to stop. At this point PC #1 is frozen and can only be re-booted. After re-booting, PC #1 FTP's back to #2, but cannot access it. On #2's Telnet Server screen appears the message "Packet Received For Invalid Port - Reset Sent" (this is the same message displayed when somebody attempts to Telnet to a DOS-PC) PC #1 cannot access #2 until #2 exits its Telnet Server and re-runs Telnet. and so on, back to the start..... - With respect to those transfers that DO succeed, they are *much* slower than transfers of the same file to a Unix workstation. I'm talking transfer speeds of only 20-40Kb/sec Q: Is there a way to change the buffer size for quicker file transmission between PC's? Is DMA used by FTP? Or is something really simple involved in both of these problems? Hardware specifics: Tiara LANCARD/E16's on DOS4.01 AT compatibles Using Tiaras PKTDRVR drivers, CONFIG.TEL uses "hardware=packet" Thank you, Michael ******************************************************************************* Michael Williams University of Arizona's Division of Neural Systems, Memory, and Aging Internet: michael@synapse.nsma.arizona.edu
