So, I've deployed a few ThousandEyes Enterprise agents over the last few weeks, mostly just as Linux packages on Ubuntu 20 VMs, but a few Appliances as well. Everything works as expected, except one oddity. On one of the Appliances, BrowserBot is n...

I'm evaluating the Nexus 2248TP Fabric Extenders as replacement for our older 3750E and 2960 switches. I have the 2248 uplinked to a pair of 5548s, both switches report the Fex "online" and successfully bundled the ports in to a vPC. Everything see...

I'm using the BGP option "remove-private-as" to strip out our private AS numbers for routes sent via the WAN. This works well. However, some paths are from Amazon VPCs end with their ASNs (usually 7224 or 9059). In this case the advertised route s...

FWIW, I tried a BrowserBot disable/re-enable on a working Appliance running the exact same image. The logs were exactly the same as the broken one, except for this one line showing up on the working agent: time="2023-09-06T18:51:36Z" level=info msg=...

Old thread, but just came across this today. My advice is first configure ip ssh source-interface on the router, then attempt to SSH to the remote server from the the CLI, and check logs on the router. I saw this: Feb 15 17:26:44.668 UTC: %SSH-3-AU...
