last night, i tried to connect my 7500/100 running mac os 8.1 to my macintosh IIsi running a/ux 3.0.1, appletalk worked, and i could successfully (after switching to ethernet) connect them via appletalk and mount a server volume, but when i got to trying out telnet, it didn't work, i used NCSA telnet and BetterTelnet 2, nwither worked, i typed in the ip address of the a/ux box (i have set up tcp/ip on the a/ux box in the commandshell) and it said connection lost or somthing like that i am suspecting the a/ux box having problems, not being set up properly, but i don't know, please help!

i assume you are on a router. restart the router.
nope, not a router, an ethernet crossover cable![Beee](https://www.applefritter.com/sites/all/modules/smiley/packs/kolobok/beee.gif)
Did you set up TCP/IP on both machines? Did you put them on the same subnet (i.e. - A/UX machine is set to 192.168.0.2 and the MacOS machine is set to 192.168.0.3 or similar) with the correct subnet mask (255.255.255.0)?
yes, A/UX is configured as 192.168.1.5 and the powermac is 192.168.1.8, the powermac is on 255.255.255.0 subnet, but the A/UX box is on the default subnet (whatever it is for the thing, somthing like fx000000f or somthing (that;s not it but it's that format, or similar anyway) ) whats strange is that i can telnet from the a/ux box to the powermac when the powermac is running a program called chat2.1pre11 or somthing similar(it is a talnet based chat program), and it works fine, even appletalk pro works, it just dosn't make sense!
Telnet is by it's nature insecure. Perhaps they close the port to it or firewall it or use a nonstandard port or something. I don't know A/UX well enough to troubleshoot that, though. I've never even seen A/UX running.
I'm assuming the telnet server (telnetd) is running on the A/UX box, right? (ps -aux | grep telnet if you're not sure).
it runs inetd until it sees network access, then it starts the required deamons
Hey, it's been 20 years but I have an answer... hope it's okay to reply. It took me a long time and completely reinstalling A/UX from scratch before I realised what the issue was:

If you're puzzled why you can't Telnet into your A/UX machine, in /etc/inittab nfs0 needs to be set to wait and net9 needs to be set to respawn, or incoming connections like Telnet and FTP don't (or, depending on what inetd you're using, connections may just sit there as inetd fails to spawn the daemon, sometimes for as long as a half an hour). This means absent other fiddling you need to be running /etc/portmap as well as /etc/inetd; you can't run just inetd. (You should probably also upgrade to jagubox inetd, which may or may not improve on this. Similarly, you might be able to get around that constraint by not using portmap services in /etc/servers, but I haven't needed to try that.)
Wow!!! Super necro thread.
20 years! That has to be some kind of record!
That makes a lot of sense, especially considering my now 20 years more experience with Linux / Unix and related systems!
Sadly the IIsi (and indeed the 7500) I was testing this on before are no longer in my possession - however I do still have a number of vintage Macs, including an SE/30, so I am tempted to crack that out and give this a proper go again!
Thankyou :)
(and much thankes to @Tom Owad for emailing me to point out that my 20 year old thread had a resolution!)
Not just a 20 year necro but the OP reappears. Definitely fits into the 100 Year Plan! (I last logged in 13 years ago I think, just found my tub o' Apple stuff)
I might not be quite so active on here anymore but I am still about, and still toying with old Macs and other vintage tech :)
