Regression: Python snmp configuration parser doesn't set 'community6' SNMP fields
Closed, ResolvedPublicBUG


The VyOS command language accepts a community string for SNMP. SNMPD, though, has different community strings for ipv4 and ipv6.

VyOS 1.1.8 correctly set both 'rocommunity' and 'rocommunity6' to the same value, but the re-written, python command parser for it doesn't set 'rocommunity6', meaning that snmp over ipv6 isn't possible.

The fix is simple - a new line in the parser template will resolve it. I'll try to get a pull request submitted to do exactly that.

Sorry guys - the fix worked, but only for community strings that are network-specific. See new pull request for the non-specific network version as well.

This produces

Aug 29 20:09:59 LR2 snmpd[3017]: /etc/snmp/snmpd.conf: line 44: Error: Address family for hostname not supported

reason is:

44: rocommunity6 fooo

IPv4 address in IPv6 rocommunity? Makes no sense to me.
