I see... I haven't actually used a PAP ISP before, so I didn't see
that. If your ISP *isn't* PAP or CHAP though, the minicom approach is
always good.

Subject: question about pppd, pty's and tty's
Date: Mon, 05 Apr 1999 21:58:28 GMT
I'm attempting to get pppd to talk to my application instead of the serial
port (long story, but I need to intercept the packets).
pppd insists on using a device, so someone recommended I use pty-redir,
and I found pty-redir-0.1, but no author attribution. The way it was
explained to me, running pty-redir on my application would open a pty,
which pppd could then talk to through it's corresponding tty.
Unfortunately, this did not work. pppd can talk to my application just
fine, but return packets are dropped on the floor. pppd never sees the
packets.
Furthermore, I wrote a quick program that just opens the pty and tty and
attempts to talk to each other.
It's as simple as
int fd = open ( "/dev/ptyrf", O_RDWR );
while (1)
{
length = read( fd, buffer, 1024 );
fprintf( stderr, buffer );
write( fd, "foo", 4 );
}
The other program is the same, but it opens /dev/ttyrf
There is also an option for sending a line after opening the file descriptor.
Here is the problem. The side that opens the pty, it receives everything
from the tty side, but it also receives everything it writes.
The tty side, it can write everything fine, but it never receives a thing.
Can anyone tell me what I'm doing wrong? This seems very very simple.

Just a thought, doesn't TCP/IP require the top and bottom segments of a
subnet be reserved as well as the top and bottom address? Try changing your
IP numbers to middle of the range and see what happens.

Sure. Or different. The other systems just have to know how to get
information to you. And you have to make sure that packets know where to
go. Eg, for your other machine, put in a "host" route to that machine on
the ehternet. Make the ppp your default. The only problem you will have
is that some of the distributions like assiging a default route to the
ethernet when you boot up. This does not work since then ppd will not
assign the default route to ppp0 You must erase that default route over
eth0 before running pppd with the defaultroute option (or you could put
the deletion and establishment ofthe ppp default route into the files
/etc/ppp/ip-up.local.)

I would be nice if you would have told us what distribution (Slackware, Redhat)
and release (3.6, 5.2,....).
I have found on Redhat 5.2, linuxconf will reset protection anytime I apply
any changes. The fix is to use linuxconf to set the pppd protection within
linuxconf.
Did you look at the protection before resetting, to very the protection
changed?
Did you look at your /var/log/messages to see if there is any information?

Subject: Problems dialing up to ISP
Date: 6 Apr 1999 03:32:05 GMT
I have followed the instrucions at the site
http://axion.physics.ubc.ca/ppp-linux.html but to no avail... seems as
though even as I have placed the noauth command in the /etc/ppp/options
file, it looks like my system is still requestion authorization from the
ISP (of course, it looks like this from my untrained eye); while tailing
the ppp log, there is the message saying "sent auth <pap>" or whatever (I
can be more specific), the key idea is that it is sending auth request in
addition to authorizing itself; you follow?
If anyone has some sort of fix or idea, please help; thanks in advance.

I can see why one might want to squeeze a little extra performance out of their
system, but i have always followed the guidline, that it is a temporary
solution. One would best be spent using resources in finding a new chip at a
good decent price..
Last time a friend attempted to overclock Linux (RedHat5.1) actually moved

Do your three IP belong to the same subnet?

Subject: pppd & Kernel support for PPP?
Date: Tue, 06 Apr 1999 02:19:36 +0000
I'm trying to set up PPP on my Linux machine (Kernel 2.2.1, pppd 2.3.7),
but I get the following error:
/usr/sbin/pppd: This system lacks kernel support for PPP. This could be
because
the PPP kernel module is not loaded, or because the kernel is
not configured for PPP. See the README.linux file in the
ppp-2.3.7 distribution.
I followed all the steps in the pppd README file, but I cant find any
mention of PPP in the kernel configuration (I'm using make xconfig). The
only place it's mentioned is under ISDN, and I've selected that.
Can somebody give me a quick run-down on what I have to do to enable
PPP? I'm rather new to dial-up on linux, so treat me that way ;)
Thanks

Hi, I've installed RedHat 5.2 perfectly about twenty times. Networking
using a NIC installs perfect, sound is (the muted test sound of someone
mumbling something) working.
Surfing the Web, and Email works perfectly with Navigator in X, but I
want the ability to use Pine without my host and domain address showing
(dammit!).
I know there's a lot more I could do for security than deleting all
accounts except for root and "usr/myself" using linuxconf.
I like the AfterStep and KDE desktops (because I'm sick of tool bars)
but want to customize them (Windows habit).
Basically, could someone recommend a link/book/advice for an advanced
(and bored with) Microsh** user?
Thanks,

I'm having a terrible time getting a 3Com 3c905 Ethernet adapter to work for
the 1st time. Any help would be greatly appreciated.
The symptoms are
- ifconfig recognizes the card
- pinging self works
- no LED indication of link to hub, and can't ping any other machine
- error in the message log - eth0: Host error, FIFO diagnostic register
2000
Additional information
- this is a dual-boot machine and under Windows 95 the card passes
diagnostics and everything works fine, so it's not hardware or interrupts
etc.
- in Win 95 I set the card to 100 Mbps half-duplex using the 3com
utilities, it shouldn't auto-detect
- Running RedHat 5.1 distribution - 2.00.35
- updated to latest driver I could find, v0.99H, no apparent difference
- dual PPro, SuperMicro motherboard, Intel 440 FX Triton chipset
