PPP in container

Nicolas o:

Our goal is to start the pppd daemon in a virtual machine. Then it is possible, for example, to connect to your DSL provider in a VM.

==Caveat==

This feature is experimental. It currently requires a version of vzctl patched with [http://git.openvz.org/?p=vzctl;a=commitdiff;h=d78a7653d983269553763d536f69de0bb5109353 this patch].

It is also necessary to run one of these 2 kernels :
* [[Download/kernel/2.6.27|2.6.27]] briullov.1 or later
* [[Download/kernel/rhel5|rhel5]] 064.4 or later

==Howto==

* ppp modules need to be loaded in the HN :

HN # modprobe ppp_async
HN # modprobe ppp_deflate
HN # lsmod | grep ppp
ppp_deflate 9793 2
zlib_deflate 21977 1 ppp_deflate
ppp_async 15169 1
crc_ccitt 6337 1 ppp_async
ppp_generic 30165 6 ppp_deflate,ppp_async
slhc 10561 1 ppp_generic

* set "ppp" feature for stoppped VE:
HN # vzctl set [VEnumber] --features ppp:on --save

* start VE :
HN # vzctl start [VEnumber]

* Prepare /dev/ppp within VE:
HN # vzctl set [VEnumber] --devices c:108:0:rw --save
HN # vzctl exec [VEnumber] mknod /dev/ppp c 108 0
HN # vzctl exec [VEnumber] chmod 600 /dev/ppp

* See if it works (as root):

VE# /usr/sbin/pppd

You should see gibberish in the standard output like

~�}#�!}!}!} }4}"}&} } } } }%}&)Q�}4}'}"}(}"p})

If there is an error message instead, something went wrong.

* From that point, you can finish your setup as in a real hardware environment.
