@ScottPack my problem is the database kinda quintuples in size when you make a text dump of it :-/

Scott Pack

@voretaq7 It'll be fine.

voretaq7

@ScottPack Clearly it won't be fine! :'(

Nathan C

@Cole I'm attempting to make a remote desktop client

I got the remote part working fine...now it's getting our receipt printers to work

which is a pain :[

Cole

@NathanC interesting.

Scott Pack

@voretaq7 Oh, you misunderstood. It'll be fine for me. You're going to have a bad time of it.

Nathan C

8:02 PM

But, work resumes on that tomorrow. Outta here. :p

voretaq7

@ScottPack As a Linux user I know EXACTLY HOW TO SOLVE THIS PROBLEM: Disk Space Overcommit! Then when the filesystem is full the OS will just delete the biggest file to make room...

Scott Pack

@voretaq7 I like it! That'll make retention scripts a sight easier.

Joel E Salas

@voretaq7 Ideally it'll be a big database table you don't need anymore!

voretaq7

@JoelESalas the benefits clearly outweigh the problems!

Joel E Salas

@voretaq7 Does postgres do one file per table?

voretaq7

8:07 PM

(I'm getting a little snippy with people who cling to the OOM killer like it's a Good Thing these days)

@JoelESalas "kinda"

WesleyDavid

(it will split tables up as needed)

@WesleyDavid you really want me to shove the 30GB of dev data up your butt?

WesleyDavid

@voretaq7 No, I want you to shove 30GB of dev data up my butt.

Your pronouns are all wrong.

Bro, do you even know my butt?

voretaq7

@WesleyDavid nope. And I'm OK with that.

WesleyDavid

Speaking of my butt, RedHat's OpenShift is intriguing me.

ObsessiveSSOℲ

Hi, I had a networking question that was related to home networking(though with multiple interfaces and more confusion) but I was told by SU to ask here anyway.Would it be acceptable?

WesleyDavid

8:39 PM

Michael Hampton

@ObsessiveSSOℲ Maybe. Do you have an existing question already?

voretaq7

@WesleyDavid foamy-demands-better-scripts

ObsessiveSSOℲ

Yes, though not posted on the site. Should I post first?

WesleyDavid

@ObsessiveSSOℲ SuperUser is sorely mistaken and needs to die painfully choking on the blood of its own children.

Dennis Kaarsemaker

@ObsessiveSSOℲ home networking is rather offtopic and this isn't a support channel. Two wrongs make a right, so go for it :)

Michael Hampton

8:40 PM

@ObsessiveSSOℲ Was it posted on SU?

ObsessiveSSOℲ

Not yet/

I asked in their chat.

voretaq7

@ObsessiveSSOℲ Home networking questions are de-facto off topic here. Ask on SU, and whoever told you to ask here should be corrected.

Michael Hampton

@ObsessiveSSOℲ OK, give us the brief outlines

WesleyDavid

@ObsessiveSSOℲ But really, if you can ask the question with zero reference to it being in a home environment, we might look at other way. Insofar as the home-nature of the question doesn't itself cause the problems, like for instance NAT redirecting to get around blocked ports, etc.

voretaq7

@WesleyDavid @ObsessiveSSOℲ ...or the question being about a crappy d-link, linksys, netgear, etc. wonder-router

WesleyDavid

8:41 PM

@voretaq7 Zyxel or go home!

ObsessiveSSOℲ

The router is as removed from the problem as possible. It's actually the OS configuration.

voretaq7

@WesleyDavid ugh, are those still around?

WesleyDavid

@voretaq7 Last time I dealt with one was '07.

Scott Pack

@voretaq7 I recommend nothing else. After all, nobody's been fired for buying Zyxel.

Dennis Kaarsemaker

@voretaq7 I have one.

works ok, except no ipv6

then again, nobody but @MichaelHampton cares about ipv6 :)

voretaq7

8:42 PM

@DennisKaarsemaker so... "piece of shit" then? :)

ObsessiveSSOℲ

So I somehow have two differing connections to the internet via two different IP addresses, and both are connected to my desktop machine (also a game server), on two different interfaces....

Michael Hampton

@ObsessiveSSOℲ "Somehow"? You didn't sign up with two different ISPs?

ObsessiveSSOℲ

I'm basically inheriting this place from ancestry.

Dennis Kaarsemaker

I read your question in root-access: no, not possible. Your ISP will block packets not originating from the IP that belongs to it.

Unless it's a really shitty isp.

Michael Hampton

@DennisKaarsemaker They should.

voretaq7

8:44 PM

@DennisKaarsemaker s/shitty/incompetent/

Hennes

@voretaq7 Whoever that was was me. And I said post of SU, but SF chat will have better answers for these questions. (Non-trvial network questions rather suck on SU). With an added 'ask carefully' and a 'it is off-topic on the site'

WesleyDavid

@DennisKaarsemaker Unless it's a ~~really shitty~~ average ISP.

voretaq7

@Hennes AND they'd start filtering quick when they got blocked for emitting bogons

ObsessiveSSOℲ

Resiential, so who would know.

voretaq7

@Hennes bonk you know better :)

Hennes

8:45 PM

Yup.

Hmm, didn;t we gain a networking SE site recently?

voretaq7

@Hennes (but thanks for sending him to chat instead of just saying "go ask over there" :-)

Dennis Kaarsemaker

@Hennes Yeah. They'll also say "not possible" :)

Michael Hampton

@Hennes It's in beta. But last I checked, they don't do home networks either

MikeyB

So if I'm seeing TCP Fast Retransmits, that means that I am dropping packets somewhere, right? Or sending them fast enough to get erroneous retransmits?

voretaq7

@Hennes yeah, but they're supposedly our networking overspill

@MikeyB probably ("I can't think of another reason you'd see them")

Scott Pack

8:46 PM

I think the networking site is intended more for the big iron neckbeards who are doing weird things like mesh MPLS networks with active/passive failovers.

Hennes

@MichaelHampton Last time I checked they were still creating their FAQ.

ObsessiveSSOℲ

But I know that I can send packets from either connection successfully. The question is that if I set the metric to prefer sending connections over the "browsing" interface, then when UDP packets for the game come in through the other, will the OS be smart enough to send the replies back through the "server" network interface?

voretaq7

@ObsessiveSSOℲ it should (because it will know it's talking through the "server" IP)

ObsessiveSSOℲ

Or will the metrics confuse it and cause it to send the datagrams back out the other way(as they're not a full two-way stream)?

Dennis Kaarsemaker

@MikeyB fast retransmit is retransmit because the sender thinks the ack is taking to long, instead of retransmit because you get a 'ttl-exceeded' or other fault indication.

voretaq7

8:48 PM

but honestly? This setup sounds like a hack fest

rebuild it, properly separating server roles from your workstation, and your life will suck a whole lot less

Hennes

It confused me enough that I was not able to give a clean answer.

Dennis Kaarsemaker

@Hennes well, you're easily confused :P

ObsessiveSSOℲ

Again, my apologies. I can;'t even see the problem at hand fully with my attention span... :P

voretaq7

@Hennes all our answers here are dirty. I mean have you seen all the cat-butt prints on our star wall?

MikeyB

@DennisKaarsemaker Hrm? fast retransmit is an optimization because the receiver received enough packets out-of-order that the sender can assume that one was dropped. That's my understanding.

Dennis Kaarsemaker

8:49 PM

@MikeyB it's not at all possible I'm misremembering an explanation once given to me. To the googles!

voretaq7

@MikeyB @DennisKaarsemaker effectively "same thing"

ObsessiveSSOℲ

Anyway, thanks!

David

whoever made this iPad FTP app are noobs

its called FTPManagerFree

voretaq7

if you got ACK1 ACK2 ACK4 ACK5 ACK6 ACK7 you can safely assume #3 is lost (and you probably waited a while)

David

except thats too long of a name for the home screen, so it shows "FTPMa...rFree"

Dennis Kaarsemaker

8:50 PM

@MikeyB en.wikipedia.org/wiki/Fast_retransmit says I got it about half right and you added the other half of the puzzle :)

MikeyB

@voretaq7 except I'm pushing 25146 packets/sec on the interface, divided among 4 streams...

voretaq7

@David F...TransferProtocol

@MikeyB and you're seeing a lot of retransmits, or just the occasional few?

MikeyB

@voretaq7 Pretty sure it's not "a lot":

[root@fleming4 ~]# tshark -i eth2 -R tcp.analysis.retransmission
Running as user "root" and group "root". This could be dangerous.
Capturing on eth2

voretaq7

NFS... I just threw up a little bit in my mouth...

MikeyB

8 retransmits over 40K packets in 18 seconds

@voretaq7 ORUCUL!

voretaq7

8:53 PM

that doesn't seem too bad though. What kind of network is this? 4xGbE?

@MikeyB OraSun

MikeyB

@voretaq7 1×10GbE

voretaq7

When two great evils combine: NFS + Oracle Licensing

pauska

NFS isn't that bad for non-critical stuff (note: VDI)

voretaq7

@pauska NFS is bad.

there are just ways to make it less bad

MikeyB

@voretaq7 Endgame is Oracle in the cloud. Hitting datastore over NFS.

voretaq7

8:59 PM

@MikeyB so it can rain on your parade?

freiheit

@voretaq7 Are there ways to make Oracle Licensing less bad?

voretaq7

I don't know what you're talking about. Oracle licensing is great.
If you're Oracle.

pauska

I've seen some nifty pNFS whitepapers crushing every single IOPS record out there. It just lacks the resilience block gives, but like I said, that works just fine for certain applications

freiheit

If you're Oracle, I will murder you in your sleep. Or when you're awake.
Really, any time I can get near you with any kind of weapon.
Including my bare hands.

MikeyB

@voretaq7 10K transactions/sec (3300B size transaction), <1ms latency, replication happening on the backend with GPFS. Looking pretty decent so far. But I'm hitting a performance plateau and trying to get around it, not sure if it's linux on client/server or networking. Or Oracle.

voretaq7

9:02 PM

@MikeyB what's your IOWAIT look like?

(and are your tables clustered on a particularly grotty index if you're having insert problems)

Jacob

I was watching my graduation ceremony until the valedictorian started a god/Jesus rant. OMFG

MikeyB

@voretaq7 On the NFS clients, around 2%. On the NFS server, 0%.

voretaq7

@Jacob GBIC loves me, this I know - for the switches tells me so....

@MikeyB OK, so it's not The Usual Suspect then :)

Q: Rack Console Setup

I rack console with mouse, keyboard and monitor. It's only output port is a vga connection. My KVM switch has USB Mouse, USB Keyboard, PS2 Keyboard, PS2 Mouse and VGA. The cables I bought have VGA on one end and VGA and 1 USB on the other. The keyboard and mouse for the console don't work. Any id...

And PC Gamers haven't been able to buy 2nd hand games since online activation, so almost 10 years

And with Steam, who gives a shit? Buying a 2nd hand game means going to the store, dealing with bratty teenagers, and then waiting for it to install from a non-existant DVD drive
