Re: [tlaplus] Ad-Hoc distributed issues



No luck here's the firewall setup on master:

onu@squidroost1:~/toolbox$ sudo ufw status verbose
Status: active
Logging: on (low)
Default: allow (incoming), allow (outgoing), disabled (routed)
New profiles: skip

To                         Action      From
--                         ------      ----
22                         ALLOW IN    Anywhere                  
Anywhere                   ALLOW IN    192.168.1.0/24            
Anywhere                   ALLOW IN    0.0.0.0                   
22 (v6)                    ALLOW IN    Anywhere (v6)             

And on the slave node:

onu@squidroost3:~sudo ufw status verbose
Status: active
Logging: on (low)
Default: allow (incoming), allow (outgoing), disabled (routed)
New profiles: skip

To                         Action      From
--                         ------      ----
Anywhere                   ALLOW IN    0.0.0.0                   

So all directions should be ok. But I still get this error.

Hi,

communication runs in all directions, i.e., the master node will also
connect to workers, and workers connect each other. Please make sure
that your network setup and firewall rules allow incoming connections on
all nodes.
If the above doesn't address your issue, please include the mapping from
nodes to IP addresses in your follow-up message.

Markus
