NAME
snmp - cups snmp backend (deprecated)
SYNOPSIS
/usr/lib/cups/backend/snmp ip-address-or-hostname
/usr/libexec/cups/backend/snmp ip-address-or-hostname
lpinfo -v --include-schemes snmp
DESCRIPTION
The DEPRECATED CUPS SNMP backend provides legacy discovery and identifi-
cation of network printers using SNMPv1. When used for discovery
through the scheduler, the backend will list all printers that respond
to a broadcast SNMPv1 query with the "public" community name. Addi-
tional queries are then sent to printers that respond in order to deter-
mine the correct device URI, make and model, and other information
needed for printing.
In the first form, the SNMP backend is run directly by the user to look
up the device URI and other information when you have an IP address or
hostname. This can be used for programs that need to configure print
queues where the user has supplied an address but nothing else.
In the second form, the SNMP backend is run indirectly using the
lpinfo(8) command. The output provides all printers detected via SNMP
on the configured broadcast addresses. Note: no broadcast addresses are
configured by default.
ENVIRONMENT
The DebugLevel value can be overridden using the CUPS_DEBUG_LEVEL envi-
ronment variable. The MaxRunTime value can be overridden using the
CUPS_MAX_RUN_TIME environment variable.
FILES
The SNMP backend reads the /etc/cups/snmp.conf configuration file, if
present, to set the default broadcast address, community name, and log-
ging level.
NOTES
The CUPS SNMP backend is deprecated and will no longer be supported in a
future version of CUPS.
CONFORMING TO
The CUPS SNMP backend uses the information from the Host, Printer, and
Port Monitor MIBs along with some vendor private MIBs and intelligent
port probes to determine the correct device URI and make and model for
each printer.
