1.4.1 - BliKVM Switch not working #180

Closed jk-andersen closed 2 months ago

jk-andersen commented 2 months ago

Updated to 1.4.1 without any problems.

I setup my BliKVM-Switch 1 in the config. Log: [2024-08-25T07:26:58.768] [INFO] file - http api request POST /api/device by admin [2024-08-25T07:26:58.831] [INFO] file - http api request POST /api/switch/getlist by admin [2024-08-25T07:26:58.854] [INFO] file - http api request POST /api/msd/images by admin [2024-08-25T07:26:58.933] [INFO] file - http api request POST /api/video/config?action=get by admin [2024-08-25T07:26:58.961] [INFO] file - http api request POST /api/switch/state?module=BliKVM_switch_v1 by admin [2024-08-25T07:26:58.966] [INFO] file - KVMDBliSwitchV1 init success, path: /dev/ttyUSB0, name: BliKVM_switch_v1

The Webinterface shows this and i cannot switch the channels:

My /usr/bin/blikvm/package.json:

{ "version": "v1.4.1", "md5value": "", "switch_handle":{ "switch_enable": 1, "switch_path": "/dev/ttyUSB0" }, "oled":{ "oled_enable": 1, "restart_show_time": 300, "interval_display_time": 5 }, "atx":{ "power_on_delay":500, "power_off_delay":5000 } }

ThomasVon2021 commented 2 months ago

What hardware version are you using?

jk-andersen commented 2 months ago

Sorry: BliKVM v4 Allwinner

ThomasVon2021 commented 2 months ago

Do you try use web ui enable? In /usr/bin/blikvm/package.json switch control no useful now.

ThomasVon2021 commented 2 months ago

Is using web control effective? The test on my end is effective.

jk-andersen commented 2 months ago

I did that now. It started working after I changed the "channelnames" back to OOTB (channel_1,...). Ít also freezes the webui at my installation (ssh still up, but webserver not responding). But the switch now works and changes the channel

ThomasVon2021 commented 2 months ago

Has the web stopped working?

jk-andersen commented 2 months ago

The Webinterface gets ujnresponsiove and does not even respond to pings when I change the channels. I tested it with the 1.4.2 release now. Here the Switch works directly after enabling in the Webinterface, but also here - When I change the channel 2 times the WebUI breaks. Only a reboot via ssh recovers this.

ThomasVon2021 commented 2 months ago

Thank you for your feedback. I will proceed with testing.

ThomasVon2021 commented 2 months ago

What did you change the channel name to? Can you provide me with it? Also, could you please list the specific steps? I repeatedly switched without reproducing.

This is my config. The log from the webui before "switching":

Can I somehow see the log on ssh? I could invsstsigate there.

ThomasVon2021 commented 2 months ago

Yes, log is in /mnt/tmp/logs/ https://github.com/ThomasVon2021/blikvm-web-server/blob/master/src/modules/kvmd/switch/kvmd_switch_v1.js I found that there is a problem with the serial port reading of the switch, and I am currently investigating whether this will cause the program on your end to crash. btw, the web process is server_app you can use "ps -aux | grep server_app" to check.

ThomasVon2021 commented 2 months ago

Can you let me remotely access your device? That way, debugging will be much simpler

ThomasVon2021 commented 2 months ago

If you can ssh, use tail -f /mnt/tmp/logs/app.log, maybe not applog, you need to check which log is the lasted. Let's see if we can make any discoveries.

jk-andersen commented 2 months ago

Ok. My debugging steps:

Verified the switch is working and connected correctly. It switches with the Hardware buttons on device. I also restarted it.

WebUI becomes unresponsive

Check of the server_app:

blikvm@mangopimcore:/mnt/tmp/logs$ ps -aux | grep server_app

I passed through the blikvm via traeffik for debugging - Will can send you the details in a private message. EDIT: currently the login is not working when passing trough a reverse proxy. I think is is connected with this: https://github.com/ThomasVon2021/blikvm/issues/151#issue-2158626855
