Proot on Fedora 20

[shower...@gmail.com]

Hello,

I was trying out proot hoping it would help me build my software in chroots faster. Unfortunately network funcionallity doesnt seem to fully work inside proot for me

I am using

./proot --version

My host distribution is

Fedora release 20 (Heisenbug)
NAME=Fedora
VERSION="20 (Heisenbug)"
ID=fedora
VERSION_ID=20
PRETTY_NAME="Fedora 20 (Heisenbug)"

And my host kernel is:

Linux squeaky-mbp 3.13.4-200.fc20.x86_64 #1 SMP Thu Feb 20 23:00:47 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I am trying this on Centos5 from OpenVZ project:

./proot -0 -R centos-tar ping google.com
ping: icmp open socket: Operation not permitted

But this works:

./proot -0 -R centos-tar host google.com                                                                                                                                     
google.com has address 173.194.41.227

I should also note that whenever I replace domains with IP addresses for things like HTTP downloads everything starts to work. So it seems like something bad happens when resolving domains.

Hello,

Ping requires privileges to forge low-level network packets (that's
why it is a setuid binary). Sadly, it is not possible to execute ping
under PRoot unless you are root. Maybe you could use nc or netcat
instead (which do not require privileges) ?

Regards,
Cedric.

Thank you for your answer

I might have illustrated problem in a wrong way. It's not really about ping but more about DNS resoluation:

When I try to download any file over HTTP inside proot: let's say:


wget http://httpbin.org
--2014-03-10 13:05:59--  http://httpbin.org/
Resolving httpbin.org... failed: Name or service not known.
wget: unable to resolve host address `httpbin.org'

It failed but performing a host lookup inside proot works:

host httpbin.org      
httpbin.org has address 54.243.116.211

Now that I replace the domain with IP it starts working:

wget http://54.243.116.211
--2014-03-10 13:08:51--  http://54.243.116.211/
Connecting to 54.243.116.211:80... connected.
HTTP request sent, awaiting response...

So it seems very strange to me that I can perform `host` command to translate domain to IP, but `wget` fails to translate it by itself...

proot copied my /etc/resolv.conf:

cat /etc/resolv.conf     
# Generated by NetworkManager
domain Home
search Home
nameserver 87.216.1.65
nameserver 87.216.1.66


If it didnt `host` command wouldnt work anyway...

Any ideas?

I confirm it's an unexpected behavior. Are you using a ~/.wgetrc file
or are there some *_proxy variables in your environment ?

[shower...@gmail.com]

I'm using unmodified fresh Centos5 64 bit image from OpenVZ. There is no .wgetrc file. Also CURL and YUM when trying to update database or install package exhibit the same behaviour. I have to replace the domains with IP addresses for YUM to work.

I also post full `env` output because I didnt find anything suspicious myself:

Hello Renim,

I'm not able to reproduce this issue using the same rootfs and same
environment. Please, could you send me the output of:

proot -R centos-5-tar -v 2 wget proot.me

Thanks in advance,
Cedric.

Hello Cédric,

Thanks for your time again. I attach and put in the mail full reproduce steps including output of the command you asked me

Hello Renim,

You're welcome. I really want to understand what's going wrong.

As of my understanding, the resolver first queries nscd through a
socket, however this latter is not bound into the guest rootfs.
Please could you try:

$ proot -R centos-5-tar -b /var/run/nscd/socket wget google.com

I think this will *not* work either since -- as of my understanding --
nscd is only a cache for "/etc/hosts" and "/etc/resolv.conf". however
I'd like to be sure the missing socket does not introduce an
unexpected behavior.

Then, the resolver parses "/etc/nsswitch.conf". This files specifies
to query the "files" database (ie. "/etc/hosts"), then the
"mdns4_minimal" database. I have no clue how this latter works, so
I'll try to get some documentation about this. In the mean time,
could you please send me the output of:

$ proot -v 2 wget proot.me

(guest rootfs == host rootfs, to understand where the behavior differ
unexpectedly)

Cédric.

Hello Cédric.

Thanks for your great help.

Actually you are right - it was about nscd. Note that Fedora doesnt come with nscd installed by default.

I had to first install and start it:

sudo yum install nscd
sudo systemctl start nscd

Afterwards things start to work like a charm:

./proot-x86_64 -R centos-5-tar -b /var/run/nscd/socket wget proot.me
--2014-03-12 13:07:30--  http://proot.me/

So my question would be if I can do something to make Centos5 skip nscd when resolving names? Or maybe proot can do something about it? At least a warning could be displayed when you mount a distro that needs it I think.

Also when running on the same file system it looks like this:
