dutiful log:

- i got to torproject.org and downloaded the browser bundle there. i haven't been able to complete bootstrapping; i've tried only a couple of the firewall busting plugins. (@19:23) - i can resolve hostnames, so i'm presently trying different irc.oftc.net mirrors to see if i can get into the tor chat and ask for advice. now i'm googling for more oftc mirrors (19:25). i got diagnostic material ... I can reach the oftc.net website but get 'no route to host' when i try to connect to port 6667.

i can get to the real internet on wifi using my phone in airplane mode, so obviously my linux system has a virus that blocks the internet. sorry for the big alarm. need to archive this thing and eventually figure out how to do incremental backups of a new system. adios until next time !

Note to other laypeople: if this happens to you, the thing to do is to call your ISP and complain, and to not take no for an answer. Keep finding new ways of engaging them, until the situation is resolved, or you are truly satisfied with it being unresolved.

Atm, I'm a guest at my parents' house, they're not here, and I don't know their account number or anything, so I'm prioritising that lower.

Today, all of google's services went down this morning, for me. I visited their status page, and they were all down, with a noticed about it. About half an hour later, they were back up.

Right now, it's 19:08-0500, and I can suddenly only reach a handful of servers. All of google's servers work. Most others don't. I can't reach github, I can't reach the tor directory servers, I can't reach most mirrors to perform system updates, but I can reach a handful of system update mirrors.

I'm getting "no route to host" for most ip addresses.

A decade ago I would have been excited to diagnose this in detail, but nowadays with severe schizophrenia it is just making me way more confused.

I have the whole internet again. Thank you all for your infinite patience. On Tue, Dec 15, 2020, 11:16 AM coderman wrote:

definitely weird behavior.

no route is messing with your route tables - you can view these.

I'm on a local-only network that for some reason is being given a default route by networkmanager. There are two default entries in my routing table. The issue goes away when the local one is removed! Thanks so much; I get so confused.

odd to get a DHCP lease, and IP, but no route.

can you log into the router itself to check logs?

I was surprised to find so few open source cable modems, and such small development communities around them, back when I had one. It's an xfinity router. But I could have run a sniffer on another system.

can you run a traceroute on the Linux system to see where the drop is?

This reveals the issue. Traceroute resolves ipv4 addresses and requests all seem to terminate at the wrong interface. Curl is resolving ipv6 addresses which get routed to the wan interface. It seems the websites and ips that didn't work were the ones without ipv6 addresses!

i like to manually set DNS servers, rather than use ISP nameservers. try switching those out. (e.g. 4.2.2.4, 4.4.4.4, 1.1.1.1, etc.) [ but to be fair, this is a routing issue, not DNS, but DNS problems might be up next... ]

Good thoughts.

have you tried turning the router off and on again? :P

Yeah I had done that ;p

good luck!

public DNS is a shit show, but with consumer routers you get to pick the least shitty option. those are less shitty than ISP nameservers, Cox and Comcast resolvers some of the worst... one alternative would be to put a Pi-Hole between you and your ISP router. then you can do things like DoH by default: https://docs.pi-hole.net/guides/dns-over-https/ best regards, P.S. yes, DoH also a shitshow, but at least your ISP can't sniff to monetize invasion of your privacy...
