daftykinsdiddledan: huh? was it dead?13:35
diddledanyeah it died on thursday13:35
daftykinswutcha do? :o13:36
diddledanflashing while on a wonky psu which decided to die immediately after the flash13:36
diddledanpsu is replaced. bios reflashed using emergency mode13:36
zmoylan-pihenceforth the pc will be known as jesus... :-P13:37
daftykinscor thats some rough luck13:41
daftykinsdiddledan: what's the emergency mode? dual BIOS board?13:44
diddledannope, there was enough bios still intact that I could hold ctrl+home to cause it to probe usb thingies for a fat32 filesystem containing an amiboot.rom file which it flashes automatically13:45
daftykinshah, jammy13:45
diddledanapparently there's two parts of the bios - the boot block and the main payload. if the boot block is still intact then it can do a blind flash like that13:46
daftykinsyeah you often see an update only erasing the main portion13:46
Nafalloyou shouldn't put nails in PSUs. just saying.14:06

nucc1daftykins: do you use dnsmasq for dhcp on your router?21:21
daftykinsi don't run a custom one capable21:22
nucc1hmmm, ok. i noticed that my desktop loses connection when it's renewing dhcp lease, and i think this is the first time i experienced this. or maybe i never just noticed it before21:23
daftykinsany reason to run DHCP at home?21:23
nucc1well, it's easy...21:23
nucc1i'll just set a long lease21:23
daftykinsi assume we're talking wired, here?21:24
nucc1nah, wifi. gave up on wires.21:27
nucc1mesh router, easily test 200+ mbps, which covers my internet and then some21:28
daftykinsugh21:28
nucc1mesh wifi access points... custom router.21:28
daftykinsi am so disappointed :)21:28
daftykinsyeah fan of buzzwords much? :)21:28
daftykinsmust be a driver quirk21:28
nucc1i'll be interested in ethernet if they could do something better than 1G21:28
nucc1the only time i need those speeds, ethernet is too slow (when I'm moving virtual machines)21:29
nucc1what driver quirk? right now, my PC is connected at 867mbps21:29
nucc1my internet is only 200mbps21:29
nucc1and i rarely need to transfer super large files, so wires are totally unnecessary21:30
daftykinstypically the kind that results in the tripping up at DHCP lease renegotiation time, like you just said21:32
daftykinsyou do realise that 2.5, 5 and 10Gbps are a thing, yeah?21:32
daftykinscertainly agree though, throwing VMs and HD video around sure does crawl21:32
daftykinseven at 110MB/sec :(21:32
nucc1i mean, won't any computer lose connection when it is renewing a dhcp lease?21:33
nucc1we've been stuck at 1gbps for a decade. and no, 2.5G and 5G ethernet aren't yet at a price point and form factor that a home user would consider21:33
daftykinsno21:33
daftykinsyeah they are actually, because between points you only need the NICs and a cable21:34
daftykinspretty cheap to grab a couple off ebay21:34
nucc1I don't see any desktop 8-port 2.5G ethernet switches21:35
daftykinsjust pointed out you don't need a switch because not every host would need to have the upgraded speed21:35
nucc1why would i want a point-to point system?21:36
nucc1and if i had a switch, it would presumably be back compatible with 1G21:36
daftykins'cause often you'd only really have two hosts you want the high speed between, then the rest can be more basic21:37
nucc1heh. I'm not about to start fiddling with cables when i want to transfer files. that would put me off the entire activity21:37
nucc1it's like the industry gave up too.21:37
daftykinsyou wouldn't, it'd be a secondary subnet permanently connected that you just map drives over21:37
nucc1i admire your enthusiasm :)21:38
daftykinsmy goodness you are chatting a lot of rubbish considering you don't seem to know about this stuff21:38
nucc1I do know about the stuff.21:38
nucc1I just value convenience.21:38
daftykinsthen why is this pretty simple suggestion tripping you up so?21:38
nucc1it's not tripping me up, it's just not worth the effort to me.21:39
nucc1i'll happily buy the next iteration of wifi accesspoints that improve speed21:39
nucc1or if they ship a 5 or 8 port ethernet switch that supports the new speeds and fits behind my set top box, i'll get one21:39
daftykinstwo cheap NICs, cat6 or better single cable run - job done, 10Gb - but then you don't have the storage necessarily capable of using it21:39
nucc1yea, i'm not saying it's not possible, but that setup is not for me.21:40
daftykinsyou already said you're on 866Mb -ac, which means you're on 2:2 stream low end -ac, not even the top tier of current wifi specs21:40
nucc1Indeed, when i need to move my VMs, i just use usb321:40
daftykinsi have the same and see ~50MB/sec tops in the same room, so under half what gigabit LAN does21:41
nucc1it's not too often. example, i did the move last week while adding a new ssd into my machine.21:41
daftykinssneakernet in your own home, bit ghetto21:42
nucc1please tell me about your snazzy wifi :)21:42
nucc1because i've never felt like my 866 mbps wifi was a bottleneck21:43
nucc1especially when compared to my Virgin Media connection.21:43
nucc1I've also found when gaming, that when virgin media is not in the mood, it doesn't matter whether i'm on wifi or ethernet21:43
daftykinshave you had a long day or something?21:45
nucc1I see it similar to camera pixels. it's not the number of pixels, it's the quality of them.21:45
daftykins50MB/sec is a file tranfer between a wired and wireless host21:46
nucc1which is plenty of speed except when you're dealing with large files21:46
daftykinswhich is when wired to wired is nice @ 110MB/sec but still crawling for HD video and VMs yeah21:47
nucc1i've done the whole wires everywhere thing before, i put in this current router (Linksys Velop) in February of this year.21:47
nucc1wifi is now good enough in my view.21:47
nucc1I stopped bothering with video files too.21:47
nucc1I used to spend more on blurays than cable, netflix, and amazon combined cost me each month21:48
nucc1so that need for speed is no longer there for me21:48
nucc1if i suddenly ended up with a 1G Internet link, then i'd have to seriously reconsider using ethernet21:48
nucc1maybe in 2025 or something, or whenever virgin media feels the need21:49
daftykinsit's unlikely anything you'd do would make use of it - as a friend in Tokyo has discovered21:49
nucc1Yes, but I'd want it just for the fun of having it21:49
daftykinsmuch like the gimmicky mesh setup i imagine21:49
nucc1No, the mesh setup was a real upgrade for me.21:50
nucc1Value coverage and stability over headline speed.21:50
nucc1I could hardly care about maxing out my internet when i'm using my phone in the conservatory21:50
nucc1but i can easily stream any video i want with no dropouts21:50
nucc1on the PC i'm sitting at now, it's got line of sight with the router, so I get pretty much as good as I can get speed for wifi21:51
nucc1which again, more than adequate for everything, save the once or twice a year transfer of big files21:51
nucc1anyway, i've just set my DHCP lease to 1 week.21:52
nucc1so connection dropouts should be less frequent now :d21:52
daftykinsbeats working out the real reason i'm sure, especially if the expiry time is when you're asleep21:53
nucc1I could just set a static IP too.21:53
nucc1I think this is normal.21:53
daftykinsnope21:53
daftykinsneither is working hard to justify choosing a slower option then complaining about speed xD21:54
daftykinshave a great evening - and don't seek me out again, please21:54
nucc1oh well... my apologies. I only wanted to know if this was normal. It's not21:55
nucc1but i'm fine with my workaround.21:55
nucc1it's not a mission critical network or anything21:55
nucc1fwiw, microsoft has a pretty good guide what should happen (IP is renewed halfway through the lease): https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-2000-server/cc958935(v%3dtechnet.10) . There's no way that speed has anything to do with this. So the DHCP theory is moot.22:45
ali1234do you get the same IP at renewal time?23:00
nucc1Yes, I can see that the IP is being obtained.23:07
nucc1ali1234: I am beginning to suspect that it may be related to my work VPN.23:07
nucc1like, if the lease renewal happens to fall while i'm connected to vpn, then it fails.23:07
nucc1and then later (like tonight) when I'm not on VPN, it is at the end of the IP and must disconnect and start anew.23:08
ali1234very possible23:08
nucc1I tested with a 1h lease, and i saw the renewal happen at 30 minutes.23:08
ali1234do you know what a split tunnel means?23:09
nucc1yes. unfortunately, i don't have admin control over my work tunnel, and a full tunnel is enforced23:09
ali1234there you go then. your DHCP request is probably being sent over the VPN tunnel when you are connected to it23:09
ali1234that will of course fail23:10
nucc1Yea. I'll verify this tomorrow.23:10
ali1234then when the lease expires, you'll be disconnected from the LAN, and so disconnected from the VPN, at which point DHCP will work again23:10
nucc1indeed. i'm afraid of thinking i've seen this happen before (memory can be untrustworthy), but I'll set a 1 hour lease time tomorrow again and see if my vpn drops after 1 hour23:11
nucc1(i mean today) :d23:11
