Unable to connect 4.5.6 GUI to Trex 2.7.5

[talentedbrute]

Using the latest Oracle 8 JDK (1.8.0_241) on Ubuntu 18.04 attempting to connect the Stateless GUI v4.5.6 to trex 2.7.5 is unsuccessful. GUI shows that it is connected, but the connect window never closes and the UI becomes unusable. Below are the logs that come from the UI.

Hi, thank you for reporting it, I'm going to look into it.

[eduser25]

Same. Just deployed new setup and experiencing same issue.

[EgorBlagov]

Hi,

I've tried it, and faced no issues:
I've checked under ubuntu 16, with latest JRE, java gui v4.5.6 (tar.gz), and TRex v2.75.

Could you attach more info, please? Also please share me your trex_cfg.yaml.

Thanks & regards,
Egor.

PS. accidentally closed issue, hence reopened.

[talentedbrute]

I was trying to do this on Ubuntu 18.04. Let me know what more information I can provide.

My trex_cf.yaml is:

### Config file generated by dpdk_setup_ports.py ###

- version: 2
  interfaces: ['00:06.0', '00:07.0']
  port_info:
      - ip: 1.1.1.1
        default_gw: 2.2.2.2
      - ip: 2.2.2.2
        default_gw: 1.1.1.1

  platform:
      master_thread_id: 0
      latency_thread_id: 1
      dual_if:
        - socket: 0
          threads: [2,3,4,5]

[EgorBlagov]

Ok, please attach me also java -version, and log with java -jar trex-stateless-gui.jar.
And if possible could you share whether it works on previous TRex version, and at what version it stops working for you?

Am I correct that at v2.74 it also didn't work?

[EgorBlagov]

Ok, I have another thought. Could you start trex-console from machine where you start the GUI, and connect to that TRex instance to check if it connects?

1. either git clone trex-core or download trex release and unpack it
2. go to scripts directory if you've cloned it, or just to v2.75 directory if you've downloaded it
3. give ./trex-console -s <ip address of trex>

[talentedbrute]

The TRex Console works just fine, I have been using that for testing. In my environment the trex server, console and stateless UI are all on the same box. All connections are made over localhost.

could you show me "advanced options" of GUI connect modal?
and also, could you confirm if it worked with v2.74 or not? I'm confused with this sentence: "This was with running against TRex 2.7.4"

[EgorBlagov]

@tareed @eduser25 could you please update

[talentedbrute]

Sorry I didnt see your comment from last week. Yes its against TRex 2.74, just a typo on my part. It will not connect using version 2.74. The trex-console app works fine. I cannot get 2.75 to build on the same box which is why I am using 2.74.

Heres the screen shot you asked for.
