The web browser will require Internet Access and Access to Yarnman. Please make sure your Jumpbox or Proxy settings in the browser allow for this configuration. If you have a proxy in your browser, you may need to bypass Yarnman's IP address.
The Webex authentication screen will be presented. Depending on your environment, this could be handled by Webex or your SSO provider, Such as Microsoft.
Webex will prompt you to allow or deny the permissions associated with your account.
Press accept and log back into yarnman when it redirects

Troubleshooting Webex login
Where possible, it's best to use a Private/Incognito session to perform the oAuth flow. There could be issues with cached logins with SSO or the wrong SSO ID being prompted, causing the oAuth to fail with a change of UserID midsession.
Troubleshooting Connectivity
For the Oauth Flow to Work Correctly, the Web browser you use needs to be able to access Webex (the Internet) and Yarnman.
DNS
Below shows the yarnman server is not able to resolve the DNS
yarnman@ym-ph4-wxc-glen [ ~ ]$ curl "https://webexapis.com" -I curl: (6) Could not resolve host: webexapis.com yarnman@ym-ph4-wxc-glen [ ~ ]$
Check DNS servers used by the yarnman server (do not edit this file)
yarnman@ym-ph4-wxc-glen [ ~ ]$ cat /run/systemd/resolve/resolv.conf # This is /run/systemd/resolve/resolv.conf managed by man:systemd-resolved(8). # Do not edit. # # This file might be symlinked as /etc/resolv.conf. If you're looking at # /etc/resolv.conf and seeing this text, you have followed the symlink. # # This is a dynamic resolv.conf file for connecting local clients directly to # all known uplink DNS servers. This file lists all configured search domains. # # Third party programs should typically not access this file directly, but only # through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a # different way, replace this symlink by a static file or a different symlink. # # See man:systemd-resolved.service(8) for details about the supported modes of # operation for /etc/resolv.conf. nameserver 10.0.0.1 search lab.yarnlab.io
to change the DNS servers, in this example, we are replacing the single DNS server with multiple DNS servers
You must first log in as the root user to modify system settings using su. exit out from the root when you are done
yarnman@ym-ph4-wxc-glen [ ~ ]$ su Password: root@ym-ph4-wxc-glen [ /var/home/yarnman ]# netmgr dns_servers --set --mode static --servers 8.8.8.8,8.8.4.4 root@ym-ph4-wxc-glen [ /var/home/yarnman ]# exit
yarnman@ym-ph4-wxc-glen [ ~ ]$ cat /run/systemd/resolve/resolv.conf # This is /run/systemd/resolve/resolv.conf managed by man:systemd-resolved(8). # Do not edit. # # This file might be symlinked as /etc/resolv.conf. If you're looking at # /etc/resolv.conf and seeing this text, you have followed the symlink. # # This is a dynamic resolv.conf file for connecting local clients directly to # all known uplink DNS servers.

Test to validate yarnman can reach webexapis.com, note 401 error as we are trying to browse without any credentials
Test Direct Access
yarnman@ym-ph4-wxc-glen [ ~ ]$ curl "https://webexapis.com" -I HTTP/1.1 401 Unauthorized x-content-type-options: nosniff trackingid: ROUTERGW_5fdd5b92-b77f-40af-9f46-ceae729d74ba vary: accept-encoding content-type: application/json date: Wed, 13 Mar 2024 03:22:59 GMT server: istio-envoy x-envoy-upstream-service-time: 1 transfer-encoding: chunked
Proxy
Depending on your environment, yarnman may also need to be able to resolve the proxy if a FQDN is required to the proxy server
You can verify yarnman can reach the proxy using curl, the http1.1 200 connection established shows the connection to the proxy was successful
Proxy without Auth
yarnman@ym-ph4-wxc-glen [ ~ ]$ curl --proxy "http://10.101.10.87:3130" "https://webexapis.com/" -I HTTP/1.1 200 Connection established HTTP/1.1 401 Unauthorized x-content-type-options: nosniff trackingid: ROUTERGW_2c5c1133-6586-42d2-a9cd-afaca8842baa vary: accept-encoding content-type: application/json date: Wed, 13 Mar 2024 03:25:18 GMT server: istio-envoy x-envoy-upstream-service-time: 2 transfer-encoding: chunked
Proxy showing user/pass is required
Proxy server requires a user/pass to connect, with the 407 error
yarnman@ym-ph4-wxc-glen [ ~ ]$ curl --proxy "http://10.101.10.87:3129" "https://webexapis.com/" -I HTTP/1.1 407 Proxy Authentication Required Server: squid/4.13 Mime-Version: 1.0 Date: Wed, 13 Mar 2024 03:26:32 GMT Content-Type: text/html;charset=utf-8 Content-Length: 3519 X-Squid-Error: ERR_CACHE_ACCESS_DENIED 0 Vary: Accept-Language Content-Language: en Proxy-Authenticate: Basic realm="Squid" X-Cache: MISS from 18a6e4fa9a26 X-Cache-Lookup: NONE from 18a6e4fa9a26:3129 Via: 1.1 18a6e4fa9a26 (squid/4.13) Connection: keep-alive curl: (56) CONNECT tunnel failed, response 407
Proxy showing user/pass to the proxy
the first 407 tells curl to try again with user:pass, 200 connect is successful to the proxy followed by the 401 to webex as expected.
