Which model? Different models have different bugs. >When I first installed ipfilter, I had an issue >with hpnp printing. I fixed that problem, but, stupidly, didn't write >down exactly what I did. The JetDirect box is a print "server". It wants to talk to your OSR5 server. Port 9100, 9101, 9102 are the common IP ports for HPNP. Also, OSR5 needs status information from the print server using SNMP on port 160. There's a list port numbers that need to be open at the bottom of: http://www.cruzio.com/~jeffl/sco/lp/printservers.htm However, almost all these ports involve connections that are outgoing from the OSR5 server. IPFilter allows all out going ports, so that should not be a problem here. It's not IPFilter. >I *thought* I changed the spec file that I >created for ipfilter's use on reboot to allow what's necessary >through. Assumption, the mother of all screwups.

The default configuration of the unspecified HP JetDirect box is to get its IP address via DHCP. Some of the early models also use bootp if that's unavailable. Punch the test button on your unspecified print server and see if the test print shows that it has an IP address. If not, telnet or use a web browser to set the IP address to whatever is specified in /etc/hosts for the printer. You should NOT be using DHCP or bootp to assign IP addresses of fixed devices (printers, routers, gateways, etc). If the IP address changes every time you have a power failure, you'll have a repetition of this exercise. >Trying to ping the printer's ip gives 'Host is down'. We power cycled >the JetDirect box, but that didn't help. The activity light on the >JetDirect flashes when the ping is running. (I'm not sure if that >means much...) Punch the test button. I'm guessing it's a 170x or 300x. You should get a test page. No IP address, no talk. >I tried using arp -s to map the IP to the MAC, but ping then just >seemed to hang (no output). arp -an shows 192.168.0.3 at >"(incomplete)"... Also, I can't ping 192.168.0.3 from any of the >machines on the LAN. If other machines can't ping the unspecified jetdirect box, then it's either at a different address, fried, misconfigured, or disconnected. I spent an hour fighting something similar. When I finally power cycled the switch (or hub) that was in between the servers and the JetDirect box, everything magically recovered. Like I said, check thy assumptions. -- Jeff Liebermann 150 Felker St #D Santa Cruz CA 95060 (831)421-6491 pgr (831)336-2558 home http://www.LearnByDestroying.com WB6SSY firstname.lastname@example.org email@example.com
