I am seeking advice as to whether it is possible for NCSA Telnet to operate in the following situation. We have a LocalTalk network of 6 macintoshes connected using PhoneNet. One of these Macs (an SE/30) has a NuvoTech SCSI/Ethernet adapter and is connected to our Universities ethernet backbone and then to the Internet. The ethernet connected Mac is running Apple Internet Router as well. What I want to be able to do is to allow LocalTalk Macs to talk to the ethernet connected mainframes (Unix) and also the Internet via the ethernet connected Macintosh. . This isn't a problem for the Mac connected directly connected to Ethernet of course. I understand that Internet Router should allow me to do this but I am having problems using Telnet - I don't seem to be able to get any response from the ethernet connected Unix machines. The Mac SE/30 is fine but not the LocalTalk connected Macs. ANy ideas? Is it my config.tel file for Telnet or is this just not possible. In the config.tel file of the LocalTalk Macs I have set hardware=AppleTalk. The ethernet connected mac is in the same zone as the other LocalTalk macs. I am using NCSA Telnet 2.3 (not the MacTCP version) Any comments/ suggestions would be appreciated. Regards Paul Freeman Monash University AUSTRALIA Email: sci213v@monu6.cc.monash.edu.au

NCSA telnet is optimized for telnet not ftp (or so the net lore goes...) If you're using the non-MacTCP version you can ensure that the message transmit unit size is set to a kilobyte, and try setting the window to about 4 kbytes. (LocalTalk packets or IP in DDP can't get that big so the default mtu and rwin are usually around 512 bytes.) If you're on MacTCP it auto-magically "does the right thing" and you're out of luck as far as twiddling the bits. {Sigh! Apple please put in an access door into your s/w - we promise to leave the default settings most of the time! :^) } Want still more speed? Enter TCP/Connect II. Gaige says he's enhanced the ftp transfer rate on the non-MacTCP version. Give him a shout. Ben Schmidt Bell-Northern Research, Ltd. Ph: (613) 763-3906 Information Technology P.O.

The Apple Internet Router only routes AppleTalk protocols. It does *not* route IP packets the way a GatorBox or FastPath does. If you want to use NCSA Telnet or other Macintosh TCP/IP software, you will need to invest in a gateway that forwards IP packets as well as AppleTalk. You can, of course, try convincing Apple to upgrade the Apple Internet Router, but if you try this, you'd better not be in a hurry... -- Amanda Walker amanda@visix.com Visix Software Inc. ...!uunet!visix!amanda -- "In this age, the mere example of nonconformity, the mere refusal to bend the knee to custom, is itself a service." --John Stuart Mill, "On Liberty" (1859)

Ph: (613) 763-3906 Hi, For FTP speed I would recommend looking into the Kinetics/Excelan/Novell product "HostAccess" aka LANWorkPlace for Macintosh. I'm biased towards this product because I worked on it. But in my limited testing I never saw NCSA or Connect II get over 40Kb/s. With HA v1.11 and TCPort v1.11 I could get 120Kb/s occasionally, and usually ran at 80Kb/s. As usual, your mileage will vary, and I honestly don't think that version of HA has much to recommend itself other than the faster speed - it's low in features and high in price. Some very small information about this product may be extracted from salespeople, but being a TCP/Mac product in an IPX/PC company, don't expect much. Sigh. I'd be interested in hearing any new numbers about ConnectII. (Hi Gage, Kurt!) Brian Bulkowski Software Type brianb@wc.novell.com <=== no longer kinetics.com

Summary - [Macs]<--LocalTalk-->[Mac, Apple Internet Router]<-Ethernet-->Unix In a word, no. When running on a Mac directly connected to Ethernet, NCSA Telnet can directly send the TCP/IP/Ethernet packet straight onto the wire. When the Mac is on LocalTalk, the TCP/IP packet is put into the data field of a DDP packet and sent to socket 72 on anything that answers an NBP LookUp for "a.b.c.d:IPADDRESS", where "a.b.c.d" is the IP address of the machine you're trying to talk to. The Apple Internet Router doesn't handle this form of encapsulation. However, you have a MultiGate there, and if you change the configuration to allow allocation of IP addresses out the EtherTalk interface (which is where the packets from the Internet Router are coming from), it will do the encap/decap/IPGATEWAY stuff for you. Phone me for configuration details (MultiGate and NCSA Telnet tricks). BTW the FastPath can do the same trick if Option 7 is set. ======================== Tom Evans tom@wcc.oz.au Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 Victoria, Australia 61-3-764-1100 FAX ...764-1179
