ppp0 not recognised

[Jantine van der Weerdt]

Hi,
ppp0 interface is not recognised. When we run the following command we get No such device. Do you have any suggestions on how to solve this issue?

root@mtcdt:~# ifconfig ppp0 up
ifconfig: SIOCGIFFLAGS: No such device

Hey there,

Have you tried following these instructions? http://www.multitech.net/developer/software/mlinux/using-mlinux/mlinux-cellular-connection/

If so, check /var/log/messages for pppd logging after you start pppd.
