Hello, I am using CUTCP/CUTE to telnet'ing to Internet hosts (e.g. nic.ddn.mil) and I am receiving the following messages : IP: fragmented packet received, frags not supported TCP: bad checksum Relevant parameters in my config.tel : mtu=512 maxseg=512 # to avoid receiving fragmented packets ! rwin=512 Any help would be great ! Thanks in advance. Marcello Frutig - FRUTIG at BRLNCC.BITNET Network Manager at Catholic University of Rio de Janeiro - BRAZIL

"mtu" should at least be 40 bytes more than "maxseg" in order to account for the length of the TCP/IP headers. Give "mtu=576" a try and see if it's any better. ...Sam -- <skl@wimsey.bc.ca>
