Yes, indeed. I admit I had not thought of that. I was writing from MY
personal perspective, With my nice modern machine and my privileged
state of not having broadband access (wink, wink). This is a rant, er
editorial; I am writing as it seems to *me*. Conceded: this is not true
As to where Linux comes in. It appears to me that PPP is the more normal
way on FreeBSD, whereas, in my own experience Linux, (or at least, the
distributions I formerly used) prefer PPPD. Therefore when KDE wrote
KPPP, (and they originally wrote it more-or-less for Linux.) They used
PPPD. There is nothing theoretically invalid about PPPD. It's just not
quite how we do things *most of the time*. Over time FreeBSD and Linux
drifted apart on this design issue, and it became something of a
characteristic of BSD, perhaps that is why Kernel PPP became less well
I should *not* have said "Did a clumsy job". I probably should have
said, "Did a less than perfect job". I guess it's kind of like trying to
make a bread recipe with rice flour instead of wheat flour. I retract
Regarding the various comments by Michael Nottebrock, Firstly: The bug
you mentioned I have not experienced. I never had problems when killing
the X-server. I cannot comment on that. I do not often kill my X-Server;
perhaps I just didn't do it frequently enough. If you believe that this
speech is a rant, you are somewhat correct. I am rather cross and it
does show. However I differ with your estimation that it is undignified.
Oh, Please! With all due respect you take things entirely too seriously.
I am obviously being over-the-sarcastic. If you feel that you "should
not dignify this rant by replying to it, but," then don't! No buts! If
you really think it is a rant. Ignore it! That's the mature thing to do!
As for your opinion that I should close the bug. I will not. An unwise
design decision has caused this problem. Because of known problems with
PPPD, KPPP should provide at least the option of using user land PPP.
You may of course differ from this view. However, unless a large outcry
arises, I will not close the bug. I think that it is, in-fact a bug.
Bugs are sometimes a bit subjective. The KPPP Developers can always
