When we use IPv6 address as Netflow server uacctd generates plugin name with "colons" ::
Example VyOS configuration
set system flow-accounting interface 'eth0' set system flow-accounting interface 'eth1' set system flow-accounting netflow engine-id '100' set system flow-accounting netflow sampling-rate '1' set system flow-accounting netflow server 2001:db8::1 port '2055' set system flow-accounting netflow source-ip 2001:db8::2 set system flow-accounting netflow timeout expiry-interval '60' set system flow-accounting netflow version '9'
uacctd doesn't like this format:
root@r1:/home/vyos# pmacctd -f /etc/pmacct/uacctd.conf -i eth0 ERROR: [/etc/pmacct/uacctd.conf:14] Syntax error: illegal brackets. Exiting. root@r1:/home/vyos#
Generated config:
root@r1:/home/vyos# cat /etc/pmacct/uacctd.conf # Genereated from VyOS configuration daemonize: true promisc: false pidfile: /var/run/uacctd.pid uacctd_group: 2 uacctd_nl_size: 2097152 snaplen: 128 aggregate: in_iface,src_mac,dst_mac,vlan,src_host,dst_host,src_port,dst_port,proto,tos,flows plugin_pipe_size: 10485760 plugin_buffer_size: 10485 imt_path: /tmp/uacctd.pipe imt_mem_pools_number: 169 plugins: nfprobe[nf_2001:db8::1],memory nfprobe_receiver[nf_2001:db8::1]: 2001:db8::1:2055 <== line 14 nfprobe_version[nf_2001:db8::1]: 9 nfprobe_engine[nf_2001:db8::1]: 100 sampling_rate[nf_2001:db8::1]: 1 nfprobe_source_ip[nf_2001:db8::1]: 2001:db8::2 nfprobe_timeouts[nf_2001:db8::1]: expint=60
To fix it we have to use dash or underscore
Also, it must use brackets
Wrong format:
nfprobe_receiver[nf_2001:db8::1]: 2001:db8::1:2055
Expected format:
nfprobe_receiver[nf_2001-db8--1]: [2001:db8::1]:2055
