Oh Gosh, that's a lot of stuff... I think I should've mentioned I'm in digest mode... 1. Douglas Quebbeman and Dan Wright wrote about scanning all possible IP adresses. Besides taking an awful lot of time, this is no longer necessary because we got a status page printed out which states the IP address to be still 111.1.0.1. 2. Lawrence LeMay wrote: assuming you have a calcomp plotter >(but i dont know which one), that it has a M971 ethernet card... That is, mostly, correct. What we're having here is a CalComp CCL600ES, a large laserprinter, hooked up to a Thick Ethernet segment together with two SUN SPARCstations (1+ and 2) (and a 486 PC for sniffing purposes). way of solving this problem is to >reset the M971 card back to factory defaults, and then setting the IP address. Unfortunately I dont some of this up. There is a >reset jumper on the ethernet card, so you power down the printer, remove the card, install the jumper, >power it up, then repeat to remove the jumper (assuming i recall the procedure correctly). We're positive that the IP address is still the one it was set to all the time (111.1.0.1) because we finally got the Ethernet Adapter Status Page printed out. This is done by setting the JP1 jumper on the 971, reinserting the card into the printer, and then powering up. (I suppose this means we don't have to do all that 'automated pinging' stuff...). I'd already found and read this page. Amazingly, they mention only two of the three LEDs my Ethernet Adapter has (IP, DATA and LINK). During the warmup phase, IP (green) and DATA (amber) are illuminated. After that, the IP LED goes on with a blink (rather 2 than 5 Hz, I'd say...), while the DATA LED flickers whenever something is transmitted on the Ethernet. The LINK LED stays off all the time. All of this seems to belong to the "NORMAL" column. 3.

However, >obviously the printer isn't responding to an ARP request for what should be its own IP address. >Therefore either it is using some other IP address, or it has lost it's configuration and needs to be broken/dormant. I agree to that. We now know the IP adress is still correctly stored. We also know the Ethernet interface is receiving every packet transmitted (flickering DATA LED). And we know that it doesn't respond - from the (incomplete); so the interface might really be kaputt - I don't hope so, however... address uses 0-bits, rather >>than 1-bits - i.e., ip 192.168.1.1 with a netmask of 192.168.1.0 and a broadcast address of >>192.168.1.0 *not* 192.168.1.255. It's archaic, but allowed. drivel :-) That might be contributing to our problem. At boot, the complete network section reads: network interfache configuration: le0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING> inet 111.0.0.14 netmask ff000000 broadcast 111.0.0.0 ether 8:0:20:9:bc:d7 ^^^^^^^^^ lo0: flags=49<UP,LOOPBACK,RUNNING> inet 127.0.0.1 netmask ff000000 4.

Oh, and "permanent": After a reboot, the old (incomplete) is there again instead of the MAC address. Very permanent indeed... Okay, that's it for this time. I hope we'll bring that printer back up again. Thanks for your given and coming assistance.
