TPLink Session SNMP error - SNMP::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known

[voytek]

I've installed 1.2.10 on Centos, setup up with Centos itself, and with WAG54G ADSL router, working good

as the router is pretty ancient, I was testing TP Link Archer VR1600v AC1600, enabled SNMP in config, can snmpwalk it, BUT, Cacti says:

Session SNMP error - SNMP::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known

or, with both ping/snmp

SNMP Information
Session SNMP error - SNMP::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known1
Ping Results
ICMP Ping timed out

BTW, I've put 1/2/3 ahead of /span in api device.php as per other thread - it now has '1' in above error ? "known1"

(viewtopic.php?p=270929)

SNMP Information
Session SNMP error - SNMP::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known1

what am I doing wrong ?

You likely entered a hostname for the description and not an IP address and that hostname is not resolvable via DNS. So, just replace the hostname with a legit IP address.

Please update lib/html_form.php and sites.php from the 1.2.x branch. All but issue 1 should be addressed. Issue #1 going to take a bit more work.

sorry, folks, apologies, you should ban me from this forum for being such an idiot (but, please don't..)

sorry.. thanks for prompt replies, I went to do a screenshot to show that I don't use hostnames only IPs and...
