LC II PDS Ethernet to iMac G4

[Snial]

Hi folks,

I have an Apple Ethernet PDS card: "Ethernet LC Twisted Pair Card: ASSY 820-0532-B". The LCII (really a Performa 400) has System 7.1 + Extensions: Apple Ethernet LC (10 Base T socket); EtherTalk Prep; EtherTalk Phase 2; Network Extension all installed. I have MacTCP and Network control panels installed. AppleTalk is enabled. I thought the first step in getting our iMac G4/1GHz to talk to the LC would be to switch AppleTalk to EtherTalk (does anything work if I don't?). I did a PRAM reset, but when I tried to use the Network control panel I got:

"Could not switch to Ethertalk due to an error. Your connection will be reset to LocalTalk."

Do I actually need EtherTalk to do this stuff, or will MacTCP just simply use the Ethernet card? The Green LED comes on. I've now tried connected from my iMac G4 on en0 (which is Ethernet), using ping -I en0 192.168.0.50 (MacTCP says that's its address). I've tried to Run Eudora to get MacTCP to start up, so that Ping might be supported as per this thread:

LC Ethernet Not Working 7.5.5

I'm trying to bring my old LC back online after replacing a failed hard drive. Back in the day, it was a web server and I had it serving up a tutorial on how to make your own old mac web server. Since installing the new HDD, I've upgraded the OS to 7.5.5 again (drive came with 7.5.3...

It'd be nice to use the Ethernet card as it would make transfers easier than using a Zip drive, I could go from LC to iMac G4 to USB then, assuming I can find a simple way to do ftp without ssh.

Do you connect using a Switch or direct cable?

Thanks for the reply, by a direct cable. The iMac G4 connects to the internet via Airport. On boot up, the LC's ethernet socket's LED blinks green then goes off for about 0.5s, then stays green. I couldn't see any flickering when I tried to ping from the iMac G4 on (as I imagine) eth0, the ethernet port.

Do you use a crossover Ethernet cable? It likely won‘t work without.

OK, thanks for the reply. I think everything upward from an iBook G3/600 automatically works out if it's a cross-over cable doesn't it? As it happens it's not a cross-over.

It does, the problem is from the LC card which is not compatible and so, does not detect any "good" signal on the line and shutdown itself

Thanks, I thought only one end needed to be able to detect if it's cross-over, but you're saying both ends do? Or are you saying that the LC card is particularly bad in this respect? I'm pretty sure I have a crossover somewhere though.

There should be nothing wrong with the LC card.

MacTCP is used for TCP connections (i.e. FTP, Telnet, SSH, ...) and unless AFP over TCP is used, then MacTCP has nothing to do with AppleTalk. Generally the only time MacTCP does anything via AppleTalk is via MacIP, which requires a MacIP server. For your scenario here, MacTCP is not a factor.

I don't recall MacTCP explicitly supporting ping requests, so if you try to ping your LC box, it won't reply to pings. Instead use a program like MacTCP Watcher to ping outside servers from the LC box.

AFP would be the fastest connection to use, but FTP is compatible with just about anything. The original post isn't clear on which one you plan on using. Both would be good though.

I suspect the error is because of a driver issue. I would create a fresh virgin system installation in a VM, copy it over, then reinstall NSI-1.5.1, AS WS 3.5. I believe most LC cards are picked up by the NSI software.

Update is still in the works, should be done sometime end of summer maybe end of year. Notably the Chart is at least 50% more accurate this time.

Today's work: A/UX 2.0.0 to Netatalk VM file server.
