Re: another panic (mix ppp and usb to taste)
On 30 Aug, Nick Hibma wrote:
/usr/sbin/ppp -quiet -direct -nat /dev/ugen0.1
I was confused by the following from ppp's man-page:
-direct
This is used for receiving incoming connections. ppp ignores
the ``set device'' line and uses descriptor 0 as the link.
which seems to imply, I don't need to care the descriptor 1 :-)
USB is NOT a serial protocol. It has nothing in common with a serial
port.
The reason I tried this, was finding a Linux how-to guide for making the
ppp over USB work between a PDA (Palm or Handsrping) and the Linux
machine. It mentioned having to install the Handspring module or
something to work with /dev/ttyUSB (sp?). I figured, I'll try it with a
ugen-device...
Could we have such a device-module too, BTW? Similar to the serial
modems we already have? Or will you just I suggest I write it myself
:-)?
P.S.: The reason why it crashes is that it looks for an endpoint
descriptor for endpoint 0 which doesn't exist. I'll fix that.
Yeah, but it seems, that just a few lines above the crash, it checks for
the sce being non-NULL... Or is it an optimization artifact?
Thanks,

While, perhaps, not the right way to do what I want (what is? aren't
serial devices the simplest?), it should not panic (nothing should
really). But it does, and quite repeatedly (some more comments after
the trace):

Well, can someone comment on the useability of gdbm? I know, it has dbm and ndbm compatibility mode and a less restrictive license. Should we switch over to it? This isn't necessary. The *current* FreeBSD libc Berkeley DB sources are completely safe -- they're under a UC Regents copyright notice. Well, but there are programming bugs in it, as was pointed out in this thread. Unless FreeBSD wants to maintain its own db, we need to select someone else's. DB3 -- despite its technical merits -- does not fit because of restrictive licensing. gdbm's license is not ideal, but acceptable -- so I'm inquiring about its technical merits... I'd welcome your comments in particular, since you are an expert in the field and there is not going to be a conflict of interest. This discussion is only regarding the possibility of making the Berkeley DB 3.X functionality available to the FreeBSD community and its customers. Well, it started out discussing the next release of nvi and promptly concluded, that it would require upgrading dbm. So, now the issue is -- which db to pick: the currently used (buggy), the DB3 (too restrictive a license, IMO), gdbm, or something else (Net or OpenBSD's?). -mi To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message

uk_UA.KOI8-U broken?
As if the __stderr/__sF troubles weren't enough, my locale settings
don't work any more. ls(1) just shows the English names for the months,
perl complains every time:
perl: warning: Please check that your locale settings:
LC_ALL = (unset),
LANG = "uk_UA.KOI8-U"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
And other programs (elm, vi) misbehave similarly. ru_SU.KOI8-R is fine.
Would this be an imperial-sponsored conspiracy ;-) ?
The /usr/share/locale/uk_UA.KOI8-U only has LC_COLLATE, LC_CTYPE,
LC_TIME, while the ru_SU.KOI8-R has LC_MESSAGES, LC_MONETARY, LC_NUMERIC
as well. But it used to work before. Perhaps, the recent changes
in locale handling require all (more) LC_* files to be present?
