Printer IP address

Michael Treacy — Wed, 28 Jul 2004 23:36:52 GMT

I have many printers installed on a HP/UX 11 machine that are referenced by name. They are setup locally in the LP Spooler as network printers. They all work, however I need to know their IP addresses. There is not a PERIPH variable in their respective /etc/lp/interface/printer_name files.
Any ideas where the IP Addresses can be found ?

Try this:
# nslookup

If you have configured DNS and /etc/nsswitch.conf file also has 'dns' on the 'hosts' entry, your DNS should be able to resolve the IP address.

nslookup can't resolve the name.
They aren't in the HOSTS file.
The printer names are defined locally and wouldn't be found on other servers.

The PERIPH variable should be in the /etc/lp/interface/ file or /usr/spool/lp/interface/ file which contains the IP address.

Try this again?
# cd /usr/spool/lp/interface/
# grep PERIPH

What output do you get?

Hi,

Just making a ping at the printer name:
#ping

Generally, for specific application use; printers are defined in /etc/hosts file. While for global the are defined in a DNS machine. The best way to determine this possibility is using the command nslookup:
#nslookup

The output will indicate you if the /etc/hosts file or DNS is used.

Rgds.

Change hosts: entry in /etc/nsswitch.conf file as,

hosts: DNS FILES

Check is there a nameserver and domain entry in /etc/resolve.conf,

domain test.com
nameserver x.x.x.x

nslookup printer-name
It will give all informations of hostname,ip-address and aliases

All hostname to address resolvation will be based on hosts: entry on /etc/nsswitch.conf file.

I've tried on 'hpnpadmin -v ' command. Fresh to me, it produces a lot of information.

But I think it still need the or you can put the for the command.

Maybe you try this again?
# cd /usr/spool/lp/interface/
# grep PERIPH

hpnpadmin -v XXXX |grep Address

where XXXX is the printer name.

If you want all:

for i in `ls /etc/lp/interface | grep -v model.orig `
do
echo $i
hpnpadmin -v $i |grep Address
done

Hi

Try

1.lpstat -v|grep null|cut -f 3 -d" "|sort -u|while read line
2. do
3. line1=$(echo $line|sed -e 's/_.*$//g')
4. echo $line1":"$(nslookup $line1 2>/dev/null)|grep answer
5. done

lpstat -v lists printers

/dev/null is normally network

remove _ to get real name

Wont work if name not based on internet name

Hi

Try this

1 ls -1 /etc/lp/interface/model.orig|while read line
2 do
3 if ishpnp $line
4 then
5 echo $line is a network printer
6 nslookup $line 2>/dev/null|grep Address
7 line1=$(echo $line|sed -e 's/_.*$//')
8 nslookup $line1 2>/dev/null|grep Address
9 else
10 echo " "
11 fi
12 done

Thanks for all the ideas...

The hpnpadmin commands give SNMP errors like this:
hpnpadmin -v mmfin05
mmfin05: Unknown printer
: Error sending SNMP request.
*** Can't find the session!

nslookup gives
device for mmfin05: /dev/null

As a last resort, the ip also prints on the test page from each printer.

Re: Printer IP address

Michael Treacy — Thu, 29 Jul 2004 09:19:45 GMT

I tried again this morning...
And the PERIPH variable is found in the /etc/lp/interface/priner_name files.

Thanks to ALL !

Hi

This is the simplest of scripts.5 lines

1. find . -type f|xargs grep ^PERIPH=|while read line
2. do
3. name=$(echo $line|cut -f2 -d"=")
4. echo $line"|"$(nslookup $name 2>/dev/null|grep Address)
5. done

It will check for network setup printers and give the IP if known

run it on directory /etc/lp/interface
