Tclsh - I/O Error

pescla — Wed, 05 Apr 2023 08:33:27 GMT

I want to add our Lab CUBE as a Webex Managed Gateway. I followed the guide step by step and when running the tclsh command, i get back:
lab-cube-1#tclsh https://binaries.webex.com/ManagedGatewayScriptProdStable/gateway_onboarding.tcl
couldn't read file "https://binaries.webex.com/ManagedGatewayScriptProdStable/gateway_onboarding.tcl": I/O error

At first i thought it was because i dont have 2GB free bootflash (only 1.96GB), but when looking at the script, i saw that it was supposed to write back a more detailed log, instead it just gave the I/O Error. I did see that there was a gateway_webex_config.json file created in the guest-share folder.

After deleting a bit more and having 2101465088 Bytes (~2.1GB) free when using dir bootflash:, i tried again - same error, so i guess the 2GB limit is not the problem?

@pescla I am not familiar with what you are trying to do here. Please note, that this Forum is for Webex API and SDK issues / questions. Is your issue related to those?

i was able to run the tclscript from local bootflash. i still get an I/O error, it seems like the issue is that it cant download the .tar for some reason:

lab-cube-1#tclsh bootflash:gateway_onboarding.tcl

The issue was that the default http source interface was the internal vrf interface, after changing it to the external the script works fine

I dont know what your exact issue is but i would suggest doing what i did: Manually download the .tcl file and upload it to flash via FTP to rule out issues with your HTTP connection
