my friend @{antranigv; antranigv@spyurk.am} have been written a series of posts on mastodon on his communication with isp support.
Every time I call my ISP support, I wish this was a real thing. https://xkcd.com/806/
— Can you please change the cable? — SIr, I did my homework before calling. — Okay but can yo… — Yes! I changed the cable, I even connected to my own router and I was able to get an address using DHCP, so not the cable nor the “adapter” are an issue.
— What DNS resolver are you using? — I run a local DNS resolver. — Can you please set the one provided with our document? — But… the issue is… I don’t get ARP responses from the gateway…
— Okay, can you please disable and enable back the adapter? — Pardon? — Click on the adapter’s icon… — I’m running Unix. — Can you please type “ifconfig eth0 down” ? — Oh no this is a BSD Unix, yes I restarted the network. /me thinking, those guys never met enp13s42 yet
Then he was asking me if I had a windows machine in my house. I said no, he said if I had a Linux machine with Network Manager, I said no.
At the end I sent him the tcpdump output (not the pcap file, just the text output), so he opened a ticket “gateway not responding”.
