RPi Awesomeness

Thoughts?

I'm not totally sure about my logic/knowledge of how Ubuntu & Python interact.

I'm also looking for more sources.

Mateo

hm... wasn’t there a problem with setting a bash alias like that?

Nathan Osman

Good scripts specify the interpreter in the shebang line.

Mateo

I thought we saw a question in chat that did that

Nathan Osman

12:17 AM

#!/usr/bin/env python2

...for example.

RPi Awesomeness

@NathanOsman So, if you call just python on a Python 3 script with the correct Python 3 shebang, it will be executed using the correct Python 3 interpreter?

Nathan Osman

Of course, that won't prevent someone from doing python3 somepy2file.py but...

@RPiAwesomeness If it's executable and has a valid shebang, you don't need to invoke the Python interpreter on the command line - it's done by the shell.

RPi Awesomeness

@NathanOsman Oh! I did not know that!

Awesome!

Nathan Osman

In fact, that's how scripting works. Bash will open the file, read the first line, and use the interpreter specified there to interpret the script.

#!/usr/bin/make -f

...is just as valid as...

Mateo

python3

#!/usr/bin/perl

Mateo

that, and it will make the python2 stuff break...

RPi Awesomeness

^ was my first thought

Nathan Osman

Yeah, a lot of stuff will break.

There's actually a better way to solve the problem.

RPi Awesomeness

But won't it just affect the specific user with that specific .bash_aliases files only when they themselves specifically call python within BASH/Terminal?

Nathan Osman

virtualenv.

Mateo

12:23 AM

@RPiAwesomeness but then every-time you try to help someone with that setup typing "python" will not work as expected

RPi Awesomeness

@Mateo Yes. That is true. But ignoring that fact (let's hope the OP knows better and can recognize when he's using a different version of Python) wouldn't my statement be true?

Nathan Osman

@RPiAwesomeness That's true.

Mateo

meh, if he knows he will just type python3...

RPi Awesomeness

I know :P Dang lazy people can't type a 3

Nathan Osman

This is one of those cases of "ignore the user's actual question and find out what they're trying to do and answer that."

Making aliases, although it will do what they want, is almost always a bad idea.

I'm positive there's a better way to do whatever it is they want.

RPi Awesomeness

12:27 AM

I'm updating my answer now.

Mateo

anyway, I forget simple stuff all the time

then go "OHHHHHHHHHHHH, NOOOOOOOOOO, It's Not Working!?!?!"

Nathan Osman

I've left him a comment.

Mateo

then remember it was something I deleted or changed...

huh, did anyone notice this new firefox feature:

RPi Awesomeness

@Mateo Ooo. Dat's fancy

Mateo

it assimilates search boxes ;)

Nathan Osman

12:34 AM

If you visit 2buntu.com, you should see that too.

It's called OpenSearch, IIRC.

Mateo

@NathanOsman if you can get past nginx

Nathan Osman

Nginx?

Mateo

RPi Awesomeness

Though, I'd rather just Google my question and tack on site:askubuntu.com. SE's search is really quite bad :P.

Nathan Osman

Wut...

RPi Awesomeness

12:35 AM

@Mateo lol

Mateo

currently what i see when going to 2buntu.com

Nathan Osman

@Mateo That only happens when the HTTP host header is missing.

It's working fine from here...

Anyone else having trouble pulling it up?

RPi Awesomeness

@NathanOsman I think I know why he wants to change the default Python version so that pip installs modules correctly. At least, that's what it sounds like from his comment on my answer.

Nathan Osman

Ima quickly check the logs.

RPi Awesomeness

I asked him to clarify that.

Nathan Osman

12:36 AM

@RPiAwesomeness Then the answer is virtualenv.

That's by far the best way to go.

Mateo

lets try chrome

RPi Awesomeness

@NathanOsman Or use python3-pip.

@Mateo You get that when you go to 2buntu.com?

Mateo

yep

Nathan Osman

Does Chrome work?

Mateo

huh

nope

RPi Awesomeness

12:38 AM

@Mateo Sounds like it's an issue on your end. I'm fine.

Nathan Osman

I've got the access logs open now.

I'm going to figure out what's going on here...

THAT IS BIZARRE.

Mateo

i just did a dist-upgrade and restart, so...

Nathan Osman

I'm bringing up the exact same page as Mateo and it's giving me a 200.

Mateo

maybe the certs it removed?

Nathan Osman

And I see a 404 in the logs for that page.

RPi Awesomeness

12:39 AM

I'm on 14.04 and no problem.

Nathan Osman

Wait a sec.

@Mateo: are you accessing over IPv6?

Mateo

not sure, whatever is default here

Fabby

@NathanOsman: You're a mod. How is it generally seen if I would add a banner for a new site on StackExchange to all of my answers on another site? (see my comment here)

Mateo

lets see...

Nathan Osman

According to the log, your IPv6 address is showing up.

RPi Awesomeness

12:40 AM

@NathanOsman Wait. You can access 2buntu's logs?

Mateo

he is the administrator

Nathan Osman

@RPiAwesomeness I'm the person who runs the server.

Journeyman Geek

@Fabby VERY badly

RPi Awesomeness

Oh. :D

That explains it :)

Nathan Osman

And also the person who designed most of the website :P

Journeyman Geek

12:41 AM

In fact? double grumpycat NO!!!.

RPi Awesomeness

@Fabby Bad bad bad.

Nathan Osman

A couple other users here have access.

RPi Awesomeness

@Fabby Don't do it.

Nathan Osman

@Fabby Prolly not a good idea... :P

Mateo

yeah ifconfig listed inet6 addresses

Fabby

12:42 AM

OK

Got it! :)

RPi Awesomeness

Downloading Vivaldi - gonna give it a go.

Nathan Osman

@Mateo Interesting. I never tested it over IPv6 even though we technically support it, so that might explain why it isn't working.

@Mateo can you try visiting quickmediasolutions.com in Chrome?

I'm going to see what happens when you try that page...

Mateo

firefox worked

Nathan Osman

Yup, HTTP 200 from here.

Mateo

chrome worked

Nathan Osman

12:44 AM

So it must be a misconfiguration on 2buntu's end.

RPi Awesomeness

Tsk tsk. A tech site that can't handle IPv6.

Nathan Osman

I wonder why it's going that. We're not even using SSL.

RPi Awesomeness

IPv6 is quite complicated though.

Nathan Osman

@RPiAwesomeness Technically, we can.

We just don't have any way to test it :P

Journeyman Geek

How so?

Nathan Osman

12:44 AM

None of us (that I know of) have IPv6 access.

Originally our server was in a SF datacenter with only IPv4 access, but we moved to NY and enabled it.

So, I guess more testing is needed.

Journeyman Geek

@NathanOsman: eh. Tunneling isn't too hard, though I've not done it on linux yet

Nathan Osman

Yeah, might be worth trying that if the site isn't working for some people.

Mateo

ertius.org/blog/nginx-and-ipv6

Journeyman Geek

is debating giving all his linux boxen AAAA records ;p

Nathan Osman

I wonder if I can tunnel over SSH through a server with IPv6 access.

@JourneymanGeek Oh we've got AAAA records for the domain. That part works :P

Mateo

12:46 AM

hm, kovyrin.net/2010/01/16/enabling-ipv6-support-in-nginx

Journeyman Geek

@NathanOsman: Oh, I mean home systems

Nathan Osman

@Mateo The funny thing is... we're running Nginx on both my website and 2buntu.

Journeyman Geek

so I can install a tunnel broker on my netbook (prolly free6) and just connect to say greekgoddess.jmgsparedomain.tld

RPi Awesomeness

Interesting thing for me - my second most upvoted answer is was actually merged with another question before getting half of those votes.

Mateo

oh, so probably not that bit that is going wrong? all is see is welcome to ngninx on 2buntu

RPi Awesomeness

12:48 AM

I found that rather intriguing.

Journeyman Geek

That sounds almost like you've bound to an ip address

and forgot to set up the ipv6 one

Nathan Osman

We're listening for IPv6 connections:

root@ny1:~# netstat -nlp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      16263/nginx

...but then the problem doesn't seem to be with accepting the connections anyway.

Journeyman Geek

hm

that website seems to work for me.

Mateo

I'll restart again, brb

Nathan Osman

12:50 AM

Okay.

@Mateo: when you get back, I checked over the logs again. Turns out that for some reason, when you accessed quickmediasolutions.com, you were using an IPv4 address.

Yeah, even Facebook is trying (and failing) to access us over IPv6 :(

I'm finding some strange things in our access logs...

37.48.74.44 - - [25/Feb/2015:19:54:04 -0500] "GET /feed/ HTTP/1.1" 404 2231 "-" "RSSOwl/2.2.1.201312301316 (X11; U; en)"
37.48.74.44 - - [25/Feb/2015:19:54:05 -0500] "GET /feed/ HTTP/1.1" 301 193 "-" "RSSOwl/2.2.1.201312301316 (X11; U; en)"

I wonder why one received a 404 and the other received a 301.

Mateo

got in this time, had to change this:

auto, dhcp only

Nathan Osman

Yup, this time I see a successful request.

Mateo

strange...

Fabby

Both 2buntu.com and www.2buntu.com show me an nginx page too....

Nathan Osman

Interesting... I just realized I don't have IPv6 setup for my mail server.

@Fabby Wut.

Hang on... BingBot just stopped by... log is scrolling pretty quick...

Fabby

1:00 AM

Nathan Osman

What about just 2buntu.com (no www)?

Fabby

samesame

and the 404 and 301 is because of RSSowl trying HTTP protocol first and something else after...

need my IP?

Nathan Osman

If you don't mind, that would be great.

It will help me filter the logs at least.

Oh wait. You're using IPv4?

Fabby

(At my mum's place...)

Yup

At home I have both.

here only IPV4

apparently not!

Nathan Osman

I can't find that IP address in the logs.

Oh yeah, I see that one.

Fabby

1:08 AM

mmh... too late to delete the other one...

Nathan Osman

I deleted it for you.

Fabby

anything else you need? (just did a traceroute)

thanks.

Nathan Osman

I think that's good.

I'll try to figure it out from here.

Thanks.

Fabby

off to sleep then!

It's fun to watch my server download an ISO from Microsoft at 30 MB/s.

Seth

Wow, time flies.

@NathanOsman 30 M*B*/s? Nice!

Nathan Osman

Hey, it's a server in a datacenter in SF.

I'm not ever going to see that in my house :P

RPi Awesomeness

Yay! I just hit 2.5k reps!

Half way to my goal for the year!

Seth

Congrats!

RPi Awesomeness

Maybe I should revise that goal to be a bit more ambitious ...

Also. We seriously need a good mobile version for chat. Or an app.

Cause accessing chat on mobile is sucky

Nathan Osman

Removing the language packs from the MSVC ISO reduced the size by 1.3 GB.

RPi Awesomeness

O.O

@Seth Thanks! And right back at you for your success at being a mod! 😀

I should write a mobile version of chat and submit it to SE...
