[05:37] <mapps> hi
[08:06] <brobostigon> morning boys and girls.
[13:35] <Azelphur> Question, has anyone here used the BT OpenReach fiber modems connected directly to a PC?
[13:35] <Azelphur> I am wanting to bypass my router to diagnose a fault
[13:38] <penguin42> they run PPPoE don't they - never dealt with them
[13:43] <Azelphur> penguin42: yea they do
[14:28] <MartijnVdS> install a PPPoE client on the PC and that should then work
[14:46]  * penguin42 assumes NM can do that
[14:54] <diddledan> Azelphur: I've done it with pfsense
[15:01] <Azelphur> MartijnVdS / diddledan having some luck, I have installed pppd, copied the pppd config from my router to the PC, dialed and got a ppp0 interface with the right IP address
[15:01] <Azelphur> buuuut, no internet connectivity. Ideas?
[15:01] <diddledan> do you have a default route assigned by pppd? (route -n)
[15:03] <Azelphur> diddledan, route -n reports a single row with iface ppp0
[15:03] <diddledan> ok it's not put-in your ISP's gateway then I guess
[15:03] <Azelphur> although it has a gateway of 0.0.0.0, that doesn't sound right
[15:03] <Azelphur> hehe
[15:03] <Azelphur> well hmm, how does one fix that?
[15:04] <diddledan> your ppp config needs the flag "defaultroute"
[15:06] <Azelphur> diddledan, thanks, you're awesome :)
[15:06] <Azelphur> now I can see if my SSH issues persist with no router involved \o/
[15:06] <diddledan> \o/
[15:07] <Azelphur> I been debugging this ssh issue for MONTHS, I shit you not
[15:08] <Azelphur> been right down the rabbit hole, basically, after a while, all my ssh sessions (inc rsync and stuff) die after a while, according to some digging I did with an openssh developer, my packets are being modified somewhere, and the server is receiving a corrupt packet, and thus terminating the connection
[15:08] <Azelphur> hence removing the router from the equasion
[15:09] <diddledan> odd
[15:09] <diddledan> very very odd
[15:10] <diddledan> did he say what was being altered about your packets or leave that as an exercise for you to discern?
[15:10] <diddledan> see TCP can fragment packets for example but that shouldn't break anything
[15:11] <diddledan> it sounds intermittent and so it's gonna be a pain to decide whether you have truly eliminated something from the equation
[15:12] <Azelphur> diddledan, left it for me, although I do have the SSH loks
[15:12] <Azelphur> logs*
[15:12] <Azelphur> diddledan, well, I've never had a rsync work for more than 20 minutes
[15:12] <penguin42> Azelphur: Have you tried adding a ServerAliveInterval to your ssh config?
[15:12] <Azelphur> so basically, if my connection doesn't drop within the hour, it's the router.
[15:13] <Azelphur> yes
[15:13] <penguin42> hmm
[15:13] <Azelphur> and ClientAliveInterval, both at various values, and I've tried rsyncd (works fine)
[15:13] <Azelphur> and I've tried different client and server hardware and OSes
[15:14] <diddledan> it might be your ISP
[15:15] <diddledan> and you've already thought of your router. what else hasn't been eliminated....? I can't think of anything else
[15:15] <diddledan> maybe your NIC
[15:15] <Azelphur> can't be NIC - tried different hardware
[15:15] <Azelphur> (on both ends)
[15:15] <diddledan> kk
[15:15] <Azelphur> yea, really eliminates it to router or ISP
[15:16] <diddledan> or potentially the last mile
[15:16] <diddledan> something wonky with your line
[15:18] <Azelphur> indeed
[15:18] <Azelphur> I'm hoping it's the router
[15:18] <Azelphur> or possibly a dodgy switch
[15:18] <diddledan> if you can get a duplicate openreach modem thingy you can eliminate that as well
[15:19] <diddledan> I haven't looked to see how expensive they are though
[16:13] <daftykins> o0
[16:13] <daftykins> i've got one of the openreach VDSL transceivers with modified firmware, don't use it but played around a bit - was £8 off ebay a bit ago :D
[16:15] <penguin42> what's modified about it?
[16:15] <diddledan> rooted I guess
[16:16] <daftykins> the alternative firmware gives you better stats, also lets the thing use one of its' two ports for NAT so you can have it act as a wired only router instead of just a dumb modem
[16:16] <daftykins> it's the Huawei original vs. the BT branded and simplified, i think
[16:17] <daftykins> Azelphur: very anecdotal but i had an issue a while back where my connection would drop a couple of packets for *anything* for a couple of seconds every half hour or hour, or similar - i could spot it easiest with an internet radio stream + a tonne of pings running from my file server
[16:18] <daftykins> interestingly dropping the term 'packet loss' had me transferred off 1st line telco support to someone else, so eventually traced it to a faulty line card in the exchange
[16:28] <daftykins> i had pings running to google, the first hop in the data centre of my ISP that replied and the router - it showed the first two dropping a couple of packets but the last being fine
[21:47] <SebthreeBQM10HD> hi
[22:01] <SebthreeBQM10HD> anyone about?
[22:04] <m0nkey_> Science has gone too far! https://i.imgur.com/w8hNyPx.jpg
