Hello guys
@NathanOsman are u around?
I need your help buddy
 
Nathan Osman
Nathan Osman
I'm here.
 
Lucio
Lucio
Hey great
Would you consider a smart idea to connect a SSD into a USB 2.0 connector?
 
Nathan Osman
Nathan Osman
Anything connected to USB 2.0 is limited to 480 Mbps theoretical maximum.
So you'll never see any data transfer speeds faster than that.
 
Lucio
Lucio
I see
 
Nathan Osman
Nathan Osman
1:45 AM
Since most mechanical disk drives sold these days offers speeds well in excess of that number, the only advantage of the SSD is low seek times.
What are you comparing this against?
 
Lucio
Lucio
The problem is I'm buying a laptop with just 1 SATA
I want have a SSD & HDD
 
Mateo
Mateo
does it have usb3?
 
Lucio
Lucio
yeah, externally
I have no idea if I can use that internally :/
 
Nathan Osman
Nathan Osman
@Lucio SATA or eSATA?
Ah, I see.
 
Mateo
Mateo
I would put the ssd in the laptop so the the system benefits on boot
 
Lucio
Lucio
1:47 AM
^ inherit
 
Nathan Osman
Nathan Osman
^--- this
Stick the SSD in the machine and use an external HD.
 
Mateo
Mateo
you can't clone and put it in?
 
Lucio
Lucio
just SATA, the laptop (by fabric) it comes with a HDD
 
Nathan Osman
Nathan Osman
Does the external HDD need to be portable?
 
Mateo
Mateo
 
Lucio
Lucio
1:48 AM
the idea is to have my working OS on the SSD. An a HDD to install ubuntu and have fun with it
working OS == windows
 
Nathan Osman
Nathan Osman
@Mateo At my last job, I had a Dell that required disassembling the laptop down to the chasis in order to replace the HDD :P
 
Lucio
Lucio
@Mateo Of course I would do so
 
Mateo
Mateo
@NathanOsman oh, well... um, it that case...
 
Lucio
Lucio
heh, is all yours :P
 
Nathan Osman
Nathan Osman
So you're wondering if connecting an HDD via USB 2.0 is going to work for Ubuntu?
 
Lucio
Lucio
1:50 AM
basically :S
 
Mateo
Mateo
it "works"
 
Nathan Osman
Nathan Osman
The answer is yes. But it will be slow. Are you sure you couldn't spare 8-10 GB on the SSD for at least /boot and /usr?
 
Lucio
Lucio
yeah, I was thinking in that
I could take 10Gb from the SSD
dunno for what piece of linux would be worth
 
Mateo
Mateo
you could get a usb 3 one too, or did you have the harddrive already
 
Lucio
Lucio
nop
selecting the components still
but yeah, I could use USB 3 for an external HDD
 
Nathan Osman
Nathan Osman
1:52 AM
Another option: a network-attached HDD.
 
Lucio
Lucio
mmm
that doesn't sound like "portable"
 
Nathan Osman
Nathan Osman
That's what I have - and I can often get >80MB/s from it.
 
Mateo
Mateo
that would be better, ssd running the os on the machine, fast usb3 mechanical will do just fine for anything else including running ubuntu
 
Lucio
Lucio
Am I wrong or USB3.0 ~= SATA ?
 
Mateo
Mateo
in speed?
 
Lucio
Lucio
1:54 AM
yep
what else could matter?
 
Mateo
Mateo
the plug?
 
Lucio
Lucio
heh
 
Nathan Osman
Nathan Osman
Actually, the only thing in this house with a USB 3.0 port is the router :P
 
Mateo
Mateo
I think usb 3 wins vs eSATA
 
Lucio
Lucio
Then, I will go with that setup
 
RPi Awesomeness
RPi Awesomeness
1:57 AM
Unless, of course, your laptop SATA is SATA 1 and USB 2.0 like my laptop :P
 
Mateo
Mateo
although it's confusing because most of the internal connections they call sata...
 
RPi Awesomeness
RPi Awesomeness
Then just any old SATA laptop drive works :P
SSD wouldn't help me at all
 
Lucio
Lucio
You guys are amazing!
 
Mateo
Mateo
plus you can use it on any computer that has usb 2 as well, that is a plus to think about
 
Lucio
Lucio
oh really?
what could be an example of an external USB3 HDD? Any amazon link maybe
 
Virusboy
Virusboy
2:05 AM
Hey guys
I have a part for win8 install only whats a proper flag for it
 
Lucio
Lucio
Hi there
 
Virusboy
Virusboy
I figured out im going to use a second hdd for 98
and other Linux distros
 
Lucio
Lucio
I'm missing something here
 
Virusboy
Virusboy
how
 
Mateo
Mateo
 
Lucio
Lucio
2:08 AM
nice
 
Mateo
Mateo
of course it will go slow on usb2 so make sure your main computer has usb3
 
Lucio
Lucio
this looks sweet
what a piece of ad O.O
 
Mateo
Mateo
yeah, that looks nice
 
Lucio
Lucio
Hell boy, you guys have cheap prices there. That would cost me 3x here
 
Mateo
Mateo
I stopped buying wd though...
 
Lucio
Lucio
2:11 AM
hah, why?
 
RPi Awesomeness

Hey guys. Any idea what package aplay comes with?
And if so, how would I install that on Ubuntu snappy core?
 
Lucio
Lucio
> aplay is a command-line audio file player for the ALSA sound card driver.
 
Mateo
Mateo
becaues of the "smart ware" stuff they did with external drives a while back, had a virtural cd drive baked in that auto installed drivers and software, and needed to be removed than reformated to work on linux, not sure they are doing it any-more but...
@RPiAwesomeness you only install snaps in snappy
 
Lucio
Lucio
@Mateo yeah, I remember that.
 
RPi Awesomeness
RPi Awesomeness
@Mateo Soooo, you can't install aplay?
 
Mateo
Mateo
2:13 AM
what are you trying to do?
 
RPi Awesomeness
RPi Awesomeness
Play audio via aplay on snappy core.
What snap would it be in, or are they not that prevalent enough yet?
 
Mateo
Mateo
did you install webdm and see the store.
 
RPi Awesomeness
RPi Awesomeness
No, I haven't.
 
Mateo
Mateo
there are only like 10 things in there.
 
RPi Awesomeness
RPi Awesomeness
Ooch
 
Mateo
Mateo
2:15 AM
so do that - then you can see kind of see how they envision snappy will be used
 
RPi Awesomeness
RPi Awesomeness
Welp. That's that I guess!
 
Lucio
Lucio
I can't wait to get this computer in my hands :)
 
RPi Awesomeness
RPi Awesomeness
So, you have to package/write your own software?
 
Lucio
Lucio
@NathanOsman thanks a lot!
 
Mateo
Mateo
It's really cool @RPiAwesomeness
just not exactly what you were expecting
 
Lucio
Lucio
2:16 AM
And thanks to you too bro Mateo
:)
 
RPi Awesomeness
RPi Awesomeness
@Mateo I guess not
So, what would one do to install aplay or any other app that has not yet been snap-ified?
 
Mateo
Mateo
I bet you could make your own snap to put it in, someone did a paste bin command line app
 
Lucio
Lucio
^that
have a good night everyone
 
RPi Awesomeness
RPi Awesomeness
\o
 
Mateo
Mateo
since everything is like sandboxed apps
and they are instant uploads like the phone
 
RPi Awesomeness
RPi Awesomeness
2:18 AM
Oh yeah. And the fact that everything is sandboxed separately from each-other you can rollback changes really easily.
I like where Canonical is going with this.
 
Mateo
Mateo
totally do "snappy install webdm"
 
RPi Awesomeness
RPi Awesomeness
Will do.
 
Mateo
Mateo
and point another computer at the ip:4200
 
RPi Awesomeness
RPi Awesomeness
Thanks for the pointer things, whatever they are. G'night all
 
Mateo
Mateo
@RPiAwesomeness oh, did you figure how to set the time up on it too?

who in the world would use quantal as a server?!?!!??!!!?ONE!?
Naa I would advice to ask them all separately but it might be too soon for some. Look at python: bindings for it have been added not long ago. You can use C+ in terminal but how limited it is?! No idea. Terminal looks like a BusyBox instance. — Rinzwind Mar 2 at 9:23

Evening!
I hit an idea: is it possible to stream all the network data to a server that I administrate?
So, doing curl ipinfo.io on my comptuer, will output the ip data of the server.

@IonicăBizău A VPN probably best describes what you're suggesting.
But there are almost certainly ways to do it without the encryption that VPNs use via some sort of tunnel.

@hbdgaf But it won't tunnel all traffic, just the stuff you tell manually it to. If there's some sort of way of redirecting everything over a SSH tunnel, that would be good but I don't know enough about iptables to help.

3:32 PM
@IonicăBizău no, one sec.
trying to explain it all. it is a mouthful
tl;dr I have a QNX4 device that ONLY have serial access. I have a beagle bone black connected via serial which runs a node server already to communicate via modbus with the device, then it takes the values and communicates them to a cloud server which we can access. this allows us to read and write modbus registers.... now, the boss wants direct terminal access to the QNX device. I can't think of a way to make that work aside from capturing all output to node and sending that to the cloud server
then ofc when the user enters a command send that back to the device (via screen)
@IonicăBizău have already read that one, got me where I am.
 
Ionică Bizău
Ionică Bizău
I have no idea... :D Try to ask it on Linux & Unix. They will surely help.
 
rlemon
rlemon
screen -S myscreen -p 0 -X stuff "command" works, but I dont know how to send ALT + key and ESC and other control keys
on the flip side, if you can think of a way to get all of this working so I can just hook it to minicom on my desktop ... by all means. suggest :) 
[QNX] -> serial -> [Beagle Bone Black] -> ssh tunnel -> [Cloud Server] -> http(?) <- [Client PC]
current 'path' of the data
 
Ionică Bizău
Ionică Bizău
Interesting...
Probably you're doing some mad science there. :-)
 
rlemon
rlemon
mad, dunno about 'science'
 
Ionică Bizău
Ionică Bizău
mad programming or so... :p
 
rlemon
rlemon
3:38 PM
if I could just forward the pipe? (is that even a term?) from QNX to the BBB to the cloud server to the client running something like minicom... that would be ideal.
another issue, we use the cloud server because we have N number of BBB + QNX systems out there.
I know which system is on which port on the server tho.

I'll drop my question here:
I'm creating a ssh tunnel from DEVICE:A via ssh -R port:127.0.0.1:port -l username ServerIp -N to SERVER:A so I can proxy stuff on SERVER:A to DEVICE:A at 127.0.0.1:port. now I wanna ssh to the device, however this does not work. I also know the ip of the device, and the ssh port it leaves at (I think that is what I see in lsof -nPp <pid of the ssh session on SERVER:A>)
I find it is a hard setup to explain. ping me if you have suggestions or questions about it
ohh, I currently use the tunnel to proxy websocket requests from the server to the device.

@NathanOsman Something I found, might be my network and not NitroShare, but I can't send a .docx file that I created in LibreOffice - it just fails.

hrm, so If I have a 'tunnel' from device to server such that the device exists on the server as localhost:1234 <- how do I determine where this actually is in /dev

@RPiAwesomeness Are you using the DEB or the PPA?

@rlemon won't lsof tell you where that socket binds towards?
 
rlemon
rlemon
tells me ip:23422 <not real port
I'm very ignorant on all of this, so if the answer is staring me in the face I apologize for not seeing it

I head about the latest Java update containing Ask.com adware in it for OS X, anything horrible like that for the linux version? Or are we safe here? :)

at least they didn't kill mysql. small blessings.
not that I don't prefer postgres or anything...

MariaDB is going forward at a much faster pace than MySQL.

A friend across the pond was all "You really should just be using PostgreSQL for everything you know that right?" and I was all "Yeah, I know." If you're not using some nosql solution, I think PostgreS is just the standard now.
I also had to laugh heartily at this
subtlety #3 needs its own tshirt.
@rlemon lsof -i | grep TCP
 
rlemon
rlemon
I already can get that information
1 sec
I know the port on the 'server' I wanna connect back too, so I run this to get the pid. 
sudo lsof -i -n | awk '/13121/{print $2}'
once I have the pid I run : 
lsof -nPp $pid

You said you couldn't find the remote ip. What's the problem? If you've got all that, you have the remote IP already.
 
rlemon
rlemon
that gives me all sorts of fun information about it, including TCP 127.0.0.1:13211 (LISTEN) and TCP <server>:22-><remote ip>:33860 (ESTABLISHED)
what I can't understand is how, given this information and an already established tunnel, to access the terminal on the device.
like, ssh 127.0.0.1:13211
but you know, working :P
 
hbdgaf
hbdgaf
I guess I'm not following what you're asking.
 
rlemon
rlemon
[A] -> ssh tunnel -> [B] ( ssh -R port:127.0.0.1:port -l username ServerIp -N )
[B] <- ssh <- ME (ssh user@webserver.com)
I want to have direct terminal access on A, and I cannot figure how to get from B to A
A -> B is easy, because B is a webserver and A is behind a network. no forwarding required when calling out
B > A isn't as straight forward, but I'm hoping because I already established A -> B I am okay
does that make more sense? I'm sorry I have always found this setup difficult to explain.

maybe kind-of like sshing into a remote virtural box, excepet it's something connected to that server?

Q: How to SSH to a VirtualBox guest externally through a host?

JordanI have a Ubuntu VM running on my Windows 7 machine. How do I set it up so that I can access an the webserver externally through ssh? I found steps (in Setup SSH access between VirtualBox Host and Guest VMs) to be able to ssh to my guest from my host, but that still leaves me with the problem of ...

ssh virtualbox

I think what he's saying is he has SSH tunneling working, but he wants to jump back through that tunnel without establishing an outbound connection first.

hrm, let me try to rephrase once more.
 
hbdgaf
hbdgaf
So, the question changed... like a lot... from when he initially asked it.
 
rlemon
rlemon
I have a device behind a network which makes an outward ssh call to my server. the point of that is actually for websocket proxies back to the device. Now, I wanna be able to to access the terminal on the device while ssh'ing into the server.

@rlemon are you trying to hack a network with a drop in place mini computer?
 
rlemon
rlemon
no, I'm trying to hook a 20 year old embedded pc running QNX4 with no TCP to the internet via a drop in board
which i've done. now the boss wants terminal access to the QNX pc from home his office
 
Mateo
Mateo
sounds like more trouble than it is worth
 
rlemon

9:03 PM
it's worth a lot :P
the ssh tunnels are so I don't have to do anything with their network. previously we have a serial device server running we purchased from a third party, but it required router configuration and port forwarding to work. I ended up spending most days on the phone walking people through that
so we developed this solution to replace it. works like a charm, as long as I'm communicating with websockets from server to device. and modbus from device to embedded pc.
 
hbdgaf
hbdgaf
and the question changed significantly enough for me to just say fuggetaboutit and bow out.
 
rlemon
rlemon
it hasn't changed at all actually. your understanding of it may have
I assure you my problem has been persistent for the entire day :P
if you jumped in mid way, you might have seen my XY questions trying to solve the original question posted a few hours ago
 
hbdgaf
hbdgaf
"hrm, so If I have a 'tunnel' from device to server such that the device exists on the server as localhost:1234 <- how do I determine where this actually is in /dev" sounds very different than what we're talking about.

I'm creating a ssh tunnel from DEVICE:A via ssh -R port:127.0.0.1:port -l username ServerIp -N to SERVER:A so I can proxy stuff on SERVER:A to DEVICE:A at 127.0.0.1:port. now I wanna ssh to the device, however this does not work. I also know the ip of the device, and the ssh port it leaves at (I think that is what I see in lsof -nPp <pid of the ssh session on SERVER:A>)
then I thought, if I can just screen /dev/whatever I would be okay
but all I know is localhost:1234
hence that question
afk for a few minutes.

Just a note to anyone using the NitroShare PPA - the current (and likely next one or two) builds are broken. I'm making some important changes to the socket processing code.
If you want something a bit more usable, use the downloads here.
