@derobert Happily I don't currently use Windows.

@derobert thats the way to do it. The latency on that first packet though.... :)

I remember calling every ISP in San Antonio in 1998 to find out who would give dialup with a static ip. 99% of them either said no or quoted an outrageous price to rent a class C, but I finally found one that would do it for $10/mo and give me shell access to their server.

9:23 PM

up to couple years ago (about 2009) the only internet available in my area was dialup or 3g (yeah, 3g)

In wiki.debian.org/chroot what is meant by

> Check the chrooted system the presence of /proc if the chroot is not likely to be fully operational. A priori, since version debootstrap Debian/Wheezy integrates natively mount /proc and /sys

Does this mean that proc and sys for the chroot are already bind-mounted by debootstrap?

@FaheemMitha this doesn't make any sense. debootstrap creates files. It doesn't care about any mounting. That comes when you want to use the chroot.

I recommend using schroot

It takes care of things like that

did you read my tutorial on U&L?

@Gilles That does sound like a good idea.

@Gilles no

@Gilles ok

If I use schroot do I have to start the chroot process over? with debootstrap and everything?

@Gilles Tutorial on chroots?

@FaheemMitha schroot

@Gilles ok

A: How do I run 32-bit programs on a 64-bit Debian/Ubuntu?

Native support Since Ubuntu 11.04 and Debian wheezy (7.0), Debian and Ubuntu have multiarch support: you can mix x86_32 (i386) and x86_64 (amd64) packages on the same system in a straightforward way. This is known as multiarch support See warl0ck's answer for more details. In older releases, De...

I titled it this way because it was the most common use case at the time

Maybe I should change it now that multiarch has made this use case markedly less common

@Gilles Yes, maybe.

@Gilles Does schroot influence the behavior of debootstrap?

@FaheemMitha no. schroot is for using the chroot

I see you run debootstrap after creating the schroot file.

this can be done in either order

create the schroot configuration, and populate the chroot

once both are done you can use the chroot

@Gilles ok, I see. schroot -c /32

I've installed a bunch of packages already. Does that matter?

9:36 PM

@FaheemMitha no

@Gilles Ok, so schroot basically does some configuration for you?

Is this edit fine?

unix.stackexchange.com/review/suggested-edits/50742

I did some bind mounts, now they won't unmount, even though I'm not inside the chroot now.

@FaheemMitha schroot does bind mounts, copies a few files (like /etc/passwd), mounts /proc, etc.

I saw it in the review queue and I wanted to reject it since it modified the original answer.

9:38 PM

umount: /mnt/wheezychroot/dev: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))

But it was already approved.

@Gilles ok

@Ramesh I think that is ok as long as it is an improvement.

@Ramesh looks good

which granted is subjective

@Ramesh that's the definition of an edit: it modifies the post

9:39 PM

@Gilles I think he meant substantial modification, like significant addition of content.

which is relatively unusual.

@Gilles, ok, thanks. Just wanted to clarify it.

@FaheemMitha, yeah, you are right. I just wanted to clarify it. :)

Does anyone know why I can' t unmount the bind mount? This seems too trivial a question to ask on the main site, but it is annoying.

@FaheemMitha because you have a file open there

or a current directory, or a mount point, etc

@Gilles I exited the chroot. What else can I do?

this can be annoying with bind mounts, because reporting tools often can't tell the bind mount from the original

9:44 PM

@Gilles oh

@FaheemMitha background process? If you installed a package with a daemon, it may be running

suggestions on how to shut this down, then? short of rebooting

does lsof say anything?

@Gilles ah, good point. would ps in the chroot only find processes in the chroot?

@FaheemMitha no, chroots don't isolate processes

9:45 PM

@Gilles right.

have you unmounted /proc, /sys and so on in the chroot?

9:59 PM

I want to change my identicon picture. Is it possible?

@Gilles no

i just exited it

you need to unmount from the bottom up

you can't unmount /foo if there's something mounted on /foo/proc

@Ramesh yes, in the obvious place in your profile

@Gilles, I have the option only to upload picture from my PC. I do not see option for changing the default identicon.

@Ramesh so you generate whatever picture you want and upload it

you can also use gravatar instead (in fact the default identicon is provided by gravatar, it's a hash of your email address)

10:15 PM

@Gilles, what should I do to generate picture? Should I just google some picture and just paste the URL?

@Gilles ok

@Ramesh it's your choice...

@StéphaneChazelas, first time I see you here in chat window. Welcome :)

@Gilles, Ok. Thanks.

@Gilles that was it, thanks. it's so easy to miss the obvious.

What's a STIG in this context? — Gilles 8 secs ago

anyone know?

10:25 PM

@Gilles, The Security Technical Implementation Guides (STIGs) as I see here.

iase.disa.mil/stigs/index.html

probably the question is too broad?

10:46 PM

and yet more $*@&*()$&)(#* harassment

@Gilles ?

@MichaelMrozek Look, you're a moderator. That means you have to deal with flags and conflicts sometimes. Can you please deal with this without making me waste more time on mikeserv?

@Gilles My comment was the polite way to say "I see no reason why you posted this, please tell me if I'm missing something or I'm going to delete it"

@MichaelMrozek why on earth would you delete my answer?

@Gilles I think totally ignoring mikeserv is a perfectly reasonable option, if you want to do that.

10:57 PM

Because it appears to just clone the first part of his answer; did you really come up with this separately? It seems very esoteric

I'm trying not to interact with mikeserv, but deleting my answers because he doesn't like them is way beyond the line.

@MichaelMrozek seriously? You've seen me on this site for 4 years and you don't think I can come up with this stuff in less time than it would take me to read his answer?

I'm amazed that two people came up with that solution at basically the same time, but if you say so, fine. I assumed you copied the code part from his and just tried to explain how it worked

I don't claim originality: I saw the trick of using arithmetic... somewhere, I have no idea where, years ago.

Ok, I assumed wrong

I definitely knew about it before this question was asked and quite probably before Stack Exchange existed

10:59 PM

@MichaelMrozek I don't see why originality is required. Isn't it ok to post a similar reply to someone elses which attempts to clarify something? I've certainly done that in the past.

If there are rules about they would be difficult to enforce, assuming they existed.

If I'd copied his code to explain it (which I haven't... My code doesn't appear anywhere in his answer), I would have used citation formatting and included a link as acknowledgement

@FaheemMitha If you cite the answer you're copying code from, sure, although I would generally leave a comment unless I'm writing a whole lot

@FaheemMitha if you're copying text or code, you need to acknowledge your sources

@MichaelMrozek No, I mean you could just be saying the same thing independently.

@FaheemMitha If you came up with it independently, obviously you don't have to cite somebody who had nothing to do with it. In this case I assumed Gilles was using mikeserv's answer and just forgot to cite it, but I was wrong

11:01 PM

That's perfectly possible. Just because someone said it first doesn't mean you can't say it too. As for copying, sure the ethical thing would be to cite it, but it is hard to prove you didn't think of it independently.

In any case, getting worked up about something like that is irrational. It is not like one is having a quarrel over research priority.

one of his other accusations of plagiarism was using awk in an answer to a question showing a failed attempt to do something in sed

because apparently the idea of trying awk if sed won't do is soooooo original

@Gilles :-)

Most of them aren't particularly persuasive. I thought this one was a fairly original idea, but apparently not

When did debian stop using backports.debian.org? Must have missed that.

@MichaelMrozek Well. this isn't research level complexity.

A: How to get green/red terminals under OpenBSD?

Each shell has its own way of expanding the prompt. OpenBSD's ksh is pdksh. See its prompt settings in the manual, under the PS1 parameter. The way ksh works is that it performs parameter substitution, command substitution and arithmetic substitution (all the $ expansions) on the value of PS1 be...

is this enough to request the deletion of mikeserv's answer? I came up with the idea two years ago! Clear case of plagiarism!

11:11 PM

It's some kind of circle of plagiarism

Well, I can see we are all just one big happy family here.

You can see the system working here, where Caleb and I posted overlapping answers and benefited from each other's and Stéphane's remarks

oh, and that's also where you can see the system not working, with mikeserv's intervention

@MichaelMrozek I've been ignoring mikeserv in chat for a little while. I tried to get him to stop fighting in comments, but he refused. I intend to keep my policy of not replying to him in comments.

11:27 PM

The one big problem with not replying to him is that a lot of the stuff he says is just flat out wrong. And people believe him

What do you want me to do? LEAVE? Then they'll keep being wrong!

heh, that actually crossed my mind while I was typing that

Normally I wouldn't care, but it's the people believing him part I do care about.

@MichaelMrozek It's a circle

11:44 PM

quick question. The default gateway can be found using route command right?

@Kevin @slm No, this is a circle

@Ramesh if you have DHCP, yes

you both are dead wrong, THIS is a circle --=> ○

@Ramesh or ip route list 0.0.0.0/0

@Braiam, @Patrick, thanks.

11:59 PM

@Gilles and this is a circle with a larger radius.
