ppp
PPP Daemon for Linux, Solaris 2, *BSD, SunOS 4, Digital Unix, SVR4, NeXTStep, and Ultrix. This allows Unix machines to connect to the internet through dialup lines, using the PPP protocol, as a PPP server or client. Works with 'chat', 'dip', and 'diald', among (many) others. Supports IP, TCP, UDP and (for Linux) IPX (Novell).

Recent commentsA new version?
The [1]changelog Reports that in ppp-2.4.4!? "* Lots of bugs fixed, particularly in the area of demand-dialled and persistent connections."
I think this is worth a look, perhaps it's time to release this code...
The [2]main page reports "The latest version of ppp is version 2.4.3, released on 14 November 2004."
Looking at Debian Stable, 2.4.4rel-8. So now even FM has current information.

Project abandoned?
pppd appears to have been unmaintained for 2 years already.
Is anybody willing to step forward and adopt this codebase?
Re: pppd 3.4.3 with rp-pppoe and demand fails to reconnect
Same with me, same log characteristics:
retry in the same second of termination, but immediate modem hangup.
After downgrading from 2.4.3 of Suse9.3 to
2.4.2 of Suse9.2 it works like I was used to before,
i.e. on demand reconnect works.
pppd 3.4.3 with rp-pppoe and demand fails to reconnect
Hallo,
after using pppd 2.4.2 for a while with rp-pppoe.so (DSL) in demand mode i have now upgraded to pppd 2.4.3. At first the connect works well, but after the automatic 24 hours disconnect by Deutsche Telekom the reconnect failes. The reconnect not only fails sometimes but definitely every time the disconnect occurs. Here is what i see in the syslog during the dis/reconnect:

This seems to be a new bug in pppd 2.4.3, since it works well with pppd 2.4.2 ...

Can't you use the included BSD or Deflate compression? Besides I'd much prefer the inclusion of a standard like RFC2509 - IP Header Compression over PPP for TCP/UDP/RTP http://www.faqs.org/rfcs/rfc2509.html
