'@' Allowed in the community name?

[michelem]

Do you know if a community name like "user@example-1d" (notice the "@") is allowed in cacti?
An snmpwalk works fine but when I add the device in cacti I get "snmp error".
Thanks

I have not had problems in the past.

Do me a favor, go the about page (click the cactus) and tell me what the text at the bottom under "Cacti Variables" says.

Cacti Variables
Operating System: unix
PHP SNMP Support: no

thx

May sound crazy, but put a "\" infront of the "@". Because you don't have php snmp support and I assume you are using cmd.php as you poller, the Cacti snmp functions are calling the NET-SNMP utlities. The shell is probably causing some issues with special characters.

No OK It works.
I tried with an other host with a @ included in the community and it works, so there are some problem on that host, i'll analize it.

Thank you and sorry.

The problem was that the host hadnt the System OID setup, so about this row in host.php:

[...]
$snmp_system = cacti_snmp_get($host["hostname"], $host["snmp_community"], ".1.3.6.1.2.1.1.1.0", $host["snmp_version"], $host["snmp_username"], $host["snmp_password"], $host["snmp_port"], $host["snmp_timeout"], read_config_option("snmp_retries"),SNMP_WEBUI);

if ($snmp_system == "") {
print "<span style='color: #ff0000; font-weight: bold;'>SNMP error</span>\n";
}else{
[...]

it returned "SNMP error" beacuse the host didnt reply to the OID ".1.3.6.1.2.1.1.1.0" (System descriptor)

Yep, that would be an error.
