Hello, I can't connect to to my trove mysql DB from an instance in a selfservice network. Strange thing is I CAN connect to the trove instance via ssh: ubuntu@dozbox2:~$ telnet 192.168.0.176 22 Trying 192.168.0.176... Connected to 192.168.0.176. Escape character is '^]'. SSH-2.0-OpenSSH_7.6p1 Ubuntu-4ubuntu0.7 But I CANNOT reach the DB port from on the troave instance: ubuntu@box2:~$ telnet 192.168.0.176 3306 Trying 192.168.0.176... telnet: Unable to connect to remote host: No route to host Within the Trove instance I CAN work with the client... root@ms3:/var/log/trove# mysql -h 192.168.0.176 -u dbadmin -p -P 3306 Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 331 The security group for that trove instance allows ssh AND 3306 (see additional infos/rules below). Any help is really appreciated! ------- Additional Infos ------------------ root@voscontrol:~# openstack server show 534fe146-0d51-4848-98ed-95dc9aaf89b1 +-------------------------------------+------------------------------------------------------------------+ | Field | Value | +-------------------------------------+------------------------------------------------------------------+ | OS-DCF:diskConfig | MANUAL | | OS-EXT-AZ:availability_zone | nova | | OS-EXT-SRV-ATTR:host | voscompute2 | | OS-EXT-SRV-ATTR:hypervisor_hostname | voscompute2 | | OS-EXT-SRV-ATTR:instance_name | instance-000000d0 | | OS-EXT-STS:power_state | Running | | OS-EXT-STS:task_state | None | | OS-EXT-STS:vm_state | active | | OS-SRV-USG:launched_at | 2023-12-18T23:05:15.000000 | | OS-SRV-USG:terminated_at | None | | accessIPv4 | | | accessIPv6 | | | addresses | doznet=192.168.0.176; trovemgmt=10.10.10.134 | | config_drive | True | | created | 2023-12-18T23:04:59Z | | flavor | m1.large (72a7e41e-e0e9-48fe-abc2-8c64838e9e4a) | | hostId | 618af9a8f27a256f291621d611d30ae2186de8c2e8fa03e5a5ba2081 | | id | 534fe146-0d51-4848-98ed-95dc9aaf89b1 | | image | trove-guest-ubuntu-bionic (773aeec6-9caa-48a3-a80a-f9bf440b0d9e) | | key_name | trovekey | | name | ms3 | | progress | 0 | | project_id | d2e35c5479c441dc9ba4dba8e9b914bc | | properties | | | security_groups | name='trove_sg-27547af3-9bb0-4df5-b4ff-e85daa72c6ef' | | | name='default' | | status | ACTIVE | | updated | 2023-12-18T23:05:15Z | | user_id | a72e578837da479895fe4207107ca2fa | | volumes_attached | id='bff9037e-2831-473b-b6ae-8027ee4053dc' | +-------------------------------------+------------------------------------------------------------------+ root@voscontrol:~# openstack security group show trove_sg-27547af3-9bb0-4df5-b4ff-e85daa72c6ef +-----------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +-----------------+----------------------------------------------------------------------------------- | created_at | 2023-12-18T23:04:51Z | description | Security group for trove instance 27547af3-9bb0-4df5-b4ff-e85daa72c6ef | id | d73ff24a-5288-486b-b10b-fe9902f80e15 | name | trove_sg-27547af3-9bb0-4df5-b4ff-e85daa72c6ef | project_id | d2e35c5479c441dc9ba4dba8e9b914bc | revision_number | 3 | rules | created_at='2023-12-18T23:04:52Z', direction='ingress', ethertype='IPv4', id='0484ddff-c945-45d0-b271-7d30e7fbf619', port_range_max='3306', port_range_min='3306', protocol='tcp', remote_ip_prefix='0.0.0.0/0', updated_at='2023-12-18T23:04:52Z' | | | created_at='2023-12-18T23:04:51Z', direction='egress', ethertype='IPv6', id='27ed1225-984a-454e-86da-656de3669038', updated_at='2023-12-18T23:04:51Z' | | | created_at='2023-12-18T23:10:33Z', direction='ingress', ethertype='IPv4', id='c2c7c390-8b13-4b00-ab7c-0a8a7687ac08', port_range_max='22', port_range_min='22', protocol='tcp', remote_ip_prefix='0.0.0.0/0', updated_at='2023-12-18T23:10:33Z' | | | created_at='2023-12-18T23:04:51Z', direction='egress', ethertype='IPv4', id='d1fdc662-fc24-46bd-80db-3aca725f96aa', updated_at='2023-12-18T23:04:51Z' | | stateful | True | tags | [] | updated_at | 2023-12-18T23:10:33Z +---------------------------------------------------------------------------------------------+
