Okay, stop me if you've heard this one before...
I keep having to chase printers that for what ever good reason get their
IP addresses changed. I do not control the networks upon which these
printers reside; I am not able to setup dhcpd with pools of IPs for like
devices or reserve IPs based on MAC. I know how to FIX the problem but...
So if I type arping -c 5 192.168.n.n, I get the MAC as well as the
response back from the device. The challenge has been that I can get IP
and MAC from nmap but not printer name which I get from lpstat -v.
If I have a crib sheet with the printer names and MAC, I can reconnect.
Still bugging the customer to get reserved DHCP installed.
This is due to the DHCP server assigning a completely new lease, and
not allowing a lease renewal - it's common, and Windows hates this when
you use the LPD ports, which are assigned statically (when DNS does not
exist).
Perhaps you can assign the printer a static IP address internally?
I use BIND, and the default behavior is to renew the lease, but I have
control over my DHCP configs. Some smaller offices will use a single
Linksys router, which also does not do renewals (but DD-wrt does).
