VPN connection hangs with message "Cannot determine ethernet address for proxy ARP"

[sohail]

Binary package hint: pptp-linux

See summary.

This worked fine in 6.06 but is broken in 6.10 (just upgraded this morning)

What can I do to get more information?

Thanks!

PS: Everything else works fine!

This is broken for me too. It worked in Dapper, but died during the update to Edgy (tried on i386, AMD64, and PPC). Cannot connect to PPTP using either kvpnc, or the pptpconfig program. (pptpconfig is not in the Ubuntu repositories, but I'm of the opinion it should be added. http://quozl.linux.org.au/pptp/pptpconfig/0-README.phtml)

Please note the comments below from an email discussion of the problem with the developer of pptpconfig (he believes the real problem is changes to pppd):

Thanks.

Yeah, sorry, they were not all package names. pptp-linux and ppp are
the names on Debian where I do my development.

pppd is not behaving as it did before. The lines showing the addresses
came from pppd, and yet they appeared after the stop was requested.

Please try debug mode from the command line, as per the FAQ. This
will exclude pptpconfig and tell us whether the problem is due to a
change in the default ppp package configuration.

http://pptpclient.sourceforge.net/howto-diagnosis.phtml#debug shows how.

Send the output to the mailing list after cleaning it of anything risky
for you.

I've a vague memory there's a pppd option that can cause this behaviour,
and it may be that your upgraded system uses that option by default now.

They are side-effects.

Ooops, this didn't help me ... it was apparently a guess, or it has
since stopped working.

Is this still an issue in Hardy? If so, what about in Intrepid?

Hi, no longer a problem in Hardy. Apologies for not responding earlier.
