Trying to test this project: [https://github.com/robcowart/elastiflow](https://github.com/robcowart/elastiflow) **Issue:** When running logstash version 6.2.2, enabling ipv6 fails but when i enable with version 5.6.8 it passes and pumps data to elasticsearch. Not sure is this is logstash issue or a plugins issue. **failing** logstash host `v6.2.2`: ```auto [root@localhost conf.d]# /usr/share/logstash/bin/logstash-plugin list --verbose | grep flow logstash-codec-netflow (3.11.2) logstash-codec-sflow (2.0.2) [root@localhost conf.d]# /usr/share/logstash/bin/logstash --version logstash 6.2.2 ``` Logs i receive from the **failing** logstash host `/var/log/logstash/logstash-plain.log`: [link](https://pastebin.com/raw/asSE0se2) ################### **working** logstash host `5.6.8`: ```auto [root@elastiflow-lab ~]# /usr/share/logstash/bin/logstash-plugin list --verbose | grep flow logstash-codec-netflow (3.11.2) logstash-codec-sflow (2.0.2) [root@elastiflow-lab ~]# /usr/share/logstash/bin/logstash --version logstash 5.6.8 ``` Logs i receive from the **working** logstash host `/var/log/logstash/logstash-plain.log`: [link](https://pastebin.com/raw/CQ3UDNUx) ################### inputs that i use for both logstash hosts: ```auto input { # Netflow udp { id => "input_udp_netflow6" host => "${ELASTIFLOW_NETFLOW_HOST6:[::1]}" port => "${ELASTIFLOW_NETFLOW_PORT:2055}" codec => netflow { versions => [5,9] } type => "netflow" } # sFlow udp { id => "input_udp_sflow6" host => "${ELASTIFLOW_SFLOW_HOST6:[::1]}" port => "${ELASTIFLOW_SFLOW_PORT:6343}" codec => sflow { } type => "sflow" } # IPFIX tcp { id => "input_tcp_ipfix6" host => "${ELASTIFLOW_IPFIX_TCP_HOST6:[::1]}" port => "${ELASTIFLOW_IPFIX_TCP_PORT:4739}" codec => netflow { versions => [10] target => "ipfix" } type => "ipfix" } udp { id => "input_udp_ipfix6" host => "${ELASTIFLOW_IPFIX_UDP_HOST6:[::1]}" port => "${ELASTIFLOW_IPFIX_UDP_PORT:4739}" codec => netflow { versions => [10] target => "ipfix" } type => "ipfix" } } ``` Any input would be appreciated. Thank you, dave ---

I did submit a ticket on [github](https://github.com/ashangit/logstash-codec-sflow/issues/10) Hopefully something comes up ---
