up_the_irons: thanks. I just tested it and the mtu is definitely higher than 1500 but its not as high as the other vps. for instance, this ping works with 4000 bytes on both vps but only on kvr29 when I switch it to 8000 bytes ping6 fe80::21b:21ff:fe93:3e08%eth1 -M do -s 8500 so 8500 doesn't work on kvr02? also, rsync fails, using my kvr02 vps, downloading from the backup server. does not hmm.. weird just checked all int's and they are 9k maybe it's host related. kvr02 is still a Jaunty node, and kvr29 is Lucid ping6 fe80::21b:21ff:fe93:3e08%eth1 -M do -s 4034 << that one works on kvr02 ping6 fe80::21b:21ff:fe93:3e08%eth1 -M do -s 4035 << that one does not not sure if those values have any significance not sure one of the successful pings: 4042 bytes from fe80::21b:21ff:fe93:3e08: icmp_seq=1 ttl=64 time=0.416 ms yall are insane lol hazardous: i won't argue that ;) kvr03 and kvr04 on the chopping block next week lol anyone seen something like this before: http://imgur.com/DMFrist http://support.arpnetworks.com/kb/main/ntp-servers it's official are you dropping all ntp traffic at edge or something? up_the_irons: mercutio: if the ARP metal port was switched to trunk, would the OS have to be aware of, and support VLan tags? afaik yes trunk == uses vlan tags Depending on which vendor's meaning of the word 'trunk' you are using, yes. I would expect the machine to need to be able to cope with 802.1q vlan tags Windows would not qualify in this regard, would it As something suitable for use on a server, no :) Googling for "windows 802.1q" however, says that it is possible, it seems essentially, the OS will be performing some of the switching task? mnathani: yes it's like having two NICs afaik mnathani: don't worry it's easy trunk is cisco terminology afaik yeah There are fancy ethernet cards which the OS can offload the vlan tagging to (and tcp checksumming etc), but they're not common. The OS would probably be handling the tags in software it's not really like having two nics, it's like having a subdivided nic oh it's like two nics when using kvm virtual machine or such eth0.1 eth0.2 if you don't expose the root port to the vm, but instead the vlan's i call my vlan's things like vlan1705 I call them things like "mgmt" or "diskvlan" basically on bsd you just do ifconfig vlan1705 vlandev em0 vlan 1705 and it will create an interface called vlan1705 over em0 plett: most ethernet cards can offload vlan but it doesn't make any real difference uhh even cheap realtek do vlan offload afaik broadcom and intel definitely do Ahh, I didn't know it was common these days. The last time I needed to know about ethernet card specifics, it was still a rare thing plett: maybe on 10/100 cards These days all I need to know is that the on-board cards on the servers we buy are good enough for what I need to do :) plett: do you use i350s? i350s can slpit into multiple cards so you can pass a virtual machine a stub pci device, and it gets it's own queue and bypasses hypervisor Not specifically, but "buy intel" has always been a safe bet when choosing ethernet cards That's interesting you need vt-d support on the motherboard though i was going ot try it, but i don't haev any spare pci-e x4 or wider slots :( and yuo can't plug an x4 card into an x1 slot i've got no idea why So you could pass a 'raw' pci device in to a KVM guest and it would actually be tagged when it reaches the outside world That would save any virtio overheads i dunno about the tagging i wonder hwo that wroks i want to try it even more now but yeah it's more efficient it's called vmdq often http://www.intel.com/content/www/us/en/network-adapters/gigabit-network-adapters/io-acceleration-technology-vmdq.html i should learn to condense my sentences :) They've become much more common than you may think, fwiw │01:42:03 plett | There are fancy ethernet cards which the OS can offload the vlan tagging to (and tcp checksumming etc), but they're not common. The OS would probably be handling the tags in software Wasn't there some gaming NIC that was supposed to reduce latency? http://en.wikipedia.org/wiki/Killer_NIC Killer NIC :: The Killer NIC (Network Interface Card), from Killer Gaming, is designed to circumvent the Microsoft Windows TCP/IP stack, and handle processing on the card via a dedicated network processor. Most standard network cards are host based, and make use of the primary CPU. The manufacturer claims that the Killer NIC is capable of reducing network latency and lag. The card was first introduced in 2006. Hardware and Models... they got bought out by atheros the nic's performance was pretty well aligned with a good intel nic they had buggy drivers and software that accompanied the nic, and included weird stuff like host-based qos (qos for apps on a single machine) etc "bro this is totally going to reduce my gaming lag" (It was marketed towards gamers, as I recall) yep it's now an onboard option on some "gaming" motherboards lol "Anandtech noted that the people who would stand to gain the most benefit from the Killer NIC, the low-end users, would also be the ones least likely to pay $280 for a network card." hahahah Intel NICs do the job yeah, when i replaced my motherboard, i had to find one that had an intel nic and not killer or realtek that was harder than it should have been the new intel chips have lower latency than the older ones by what, .x number of ms? it's about 2/3rd of normal latency i think but even with default coalescing settings vs tuned ones mnathani: yes, your OS would need to support VLANs. But, fortunately, they all do. http://arstechnica.com/security/2014/06/at-least-32000-servers-broadcast-admin-passwords-in-the-clear-advisory-warns/ Ars Technica: "At least 32,000 servers broadcast admin passwords in the clear, advisory warns" haha, yeah m0unds: http://www.twitch.tv/inicast Serversmash - Waterson vs Mattherson server smash staticsafe: fun i saw a thing about the ps2 dev team finding a server-side cause of bad hitreg that impacts 20+% of players yeah hitreg has been horrrrrrrible for a few months now my ping to connery is less than 60, and i regularly end up having whole magazines fail to register a single hit, only to die to one huge damage impulse I've come to hate PlanetSide2 for no other reason than causing me to wonder who's still using+developing the PlayStation2. LOL Haven't had this issue with any other game either. Makes me wonder how, with as many games released as there are, only PlanetSide2 stomps over another popular abbreviation it's developed by sony too Waterson 48 - 43 damn wow up_the_irons did you check your own servers? i know it's not open to the world, but would be curious if it happening none the less. wow, 300+gbps ddos against hong kong's online voting systems yesterday guess i missed that @wa time in hong kong current time in Hong Kong;9:34:24 am HKT -> Saturday, June 21, 2014;1:34:24 am GMT -> Saturday June 21, 2014 m0unds: it's because it hasn't happened yet. AAAAAAHHHHH yesterday, 'murica time i managed to get someone scheduled to come look at my air conditioner on monday m0unds: i thought it blew up? compressor surely did Hence why it needs repair/looking at oh right i forget that it's not like an appliance that it brekas and you just get a new one hahaha, yeah wel li suppose some people repair fridges. well, this is a 4ton (48kbtu) unit and they're the most similar appliance oh Smaller AC units are more like appliances yeah this cools a whole 2300sq ft dwelling, sans garage i hate air conditioning myself but i don't live in a desert. But big, house-cooling units are big. Too big to be a simple swap out. also unholy expensive when they break warranty? negative, 8 years old damn good luck :) "normal" warranties are against defects, not "wear" haha, thanks Have fun, m0unds :) yeah, newer units have 10 year warranties if you get them svc'd yearly which costs more than getting a new one after 8 years i imagine hmmm nah haha $200/yr x 8 years vs $8000+ for a new unit $8000? wow that's way more expensive than a heat pump yeah, it's old enough to use the phased out barely in production refrigerant which is ~$120/lb and is expensive to run? can you chaneg to the new coolant? refrigerant 10+ year old fridges cost way moer to run you can, but you lose ~10-15% efficiency and run the risk of further damage so i assume it similar really? yeah, because there's no way to guarantee you've evac'd all of the oil and stuff out there's two common ones now and the oil type used for one type of refrigerant isn't the same as what's used with the other r134a is one? in smaller units, like cars and fridges oh right so it's different this is R-22 (old) and R-410a (new) r22 was in fridges? no idea it's in my air conditioning system hahaha oh r12 was i think yeah, and old cars my refrigerator is 134a iirc it's a couple years old hah, that's a ridiculous number of dead TR my fridge uses r600a dat save by waterson yeah i hate the octagon blow it up then? (jk) wish i could you should be careful about saying stuff like that someone got into mega trouble by saying something about wanting to blow up in airport after his plane was severely delayed on twitter and itw as taken out of context etc. because the NSA might misconstrue saying i want to blow up a fictional facility in a video game as intent to commit terrorist acts? oh? oh is that fictional? there's a oplitical place in this country with that name so i thought it may be in other places too well it's the city centre of one of the citys here http://www.bbc.com/news/uk-england-18607798 ahh this is what iw as thinking of http://i307.photobucket.com/albums/nn320/vulgarman/map%20stuff/PS2/octagon.jpg ahh why is it upside down? couldn't tell you :( waterson lost womp womp m0unds: OMG miscalc hahahah wow FUCK YES winnars gg, won by one point mercutio: yeah some servers are vulnerable, but all our IPMI stuff is behind a VPN, so at least that is there. I also blocked that port today, so hopefully that'll help too.
