SEMS node installation >>Launch traffic switch Fails with 404 unknow node

Yeti installation and upgrade
1

Am new in this, trying to get things work here.

I am stuck and my traffic switch would not start.

  1. On WEB interface installation >> Invoice PDF generation i did not set up
  2. On WEB interface installation >> DAP Authentication I did not set up. I will not use it unless its mandatory. Please confirm this.

i created node Id 8
Signalling ip is my server ip
port : 5060
Rcp endpoint: 127.0.0.1:7080

When launching my switch i get this error

root@Yeti-softswitch:~# service sems start
Job for sems.service failed because the control process exited with error code.
See “systemctl status sems.service” and “journalctl -xe” for details.

if i check log this is what i get

*oot@Yeti-softswitch:~# journalctl -xe**

see https://yeti-switch.org/docs/en/installation/management.html#etc-yeti-system-cfg

/etc/yeti/system.cfg should contain configuration for node 18, so you should replace in your config

...
  node 8 { }
}

with:

...
  node 18 { }
}

you should restart yeti-management to apply configuration changes

3

Done the node change to 18 in /etc/yeti/system.cfg but still when i run “service sems start” it tells me unknown node 8 and would not start service

4

Did you restart yeti-management service?

5

Yes i did and did not get any errors on restarting the yeti-management` service but on next step on launching the switch that is where i got 404 unknown node 8

6

My mistake. looks like your node id is 8, so you should define node 8 in system.cfg

7

Am still stuck even when i edit it to node 8. Do you mind have a look at my installation?

8

Could you attach your system.cfg. Looks like your configuration is not valid. Have you copied it from https://yeti-switch.org/docs/en/installation/management.html ?

9

@dmitry.s we managed resolve the issue, just a few lines in the config. /etc/sems/sems.conf , /etc/yeti/management.cfg, /etc/yeti/system.cfg. Thanks to @amitiyer he identified the problem and did a few abra ka dabra and pap the switch launched. This has been resolved

10

@erick would you kindly share which of the parameters were changed?

11

@edson /etc/yeti/system.cfg should contain node with same id as yout node_id at sems.conf

12

@edson on my set up My node ID was 8
/etc/sems/sems.conf i had set the Node ID like this node_id =8 , should be node_id = 8 , there should be a space between = and 8

also on /etc/yeti/management.cfg
My was like below

daemon {
listen = {
“tcp://127.0.0.1:4444”
}

Should be

daemon {
listen = {
“tcp://0.0.0.0:4444”
}

also in /etc/yeti/system.cfg
there were some extra lines after
rpc {
calls_show_limit = 10000
I had to remove them and the rest was violaaa
