I do not remember if this is right. If you turn off ICANON, do you really need to turn
off ECHOE?
The man page says:
ECHOE if ICANON is also set, the ERASE character erases
the preceding input character, and WERASE erases
the preceding word.
But in your case, ICANON is NOT also set.

I do not see it, but I have not done that kind of thing since about 1991 or so, so I
would not
expect to see it. What I would suggest, however, is to copy _oldio (whereever that is)
into newtio
first, and then change only the bits you absolutely must change. I know I could never
get it right
by setting everything up the way I thought it should be.

you cant login as root from a telnet session

create a user account using useradd and then log in via the telnet session
with that username. then "su" to root

I beg your pardon? I've never used BXPro. My primary GUI builder
is Perl/Tk, which is probably the reason for my experiences, which
you can infer from the above comment.

I have the mouse on the ps/2 port under Linux 2.2.17 and I have tested it
with the USB port on W98, both method work. On the USB port the refresh
rate is even higher (200).
The kernel that Mandrake 7.1 use is 2.2.16 or below, so the usb support
is an old 2.4 backport. The latest USB drivers are in 2.4 and 2.2.18pre.
You might want to try out 2.2.18pre or wait for 2.2.18. The latest
2.4test is not that stable, I couldn't even boot it the last time I tried.

Subject: NVidia GeForce 256 DDR Acceleration
Date: Tue, 21 Nov 2000 23:07:23 GMT
I am trying to get an NVidia GeForce 256 DDR working in linux. I want
the 3-D acceleration to work, specifically with IRIS Performer 2.3.1. I
had it working before in Linux Mandrake 7.1, but somehow I broke it and
couldn't get it back.
I have tried two different distros, both using NVidia drivers 0.9-5:
RedHat 7.0:
When building the nvidia kernel from either the tar.gz or rpm, I get
an error that says kernels above 2.2 are not supported and the headers
don't match. I am running the base kernel that comes with 7.0, which is
2.2.16-??. Is there something that is telling the nvidia kernel the
wrong core kernel version?
Mandrake 7.2:
The nvidia kernel builds fine, but when trying to insmod it I get
unresolved dependencies. All of them have something to do with AGP,
like agp_backend and stuff like that. The glx builds fine, but when
starting X it can't find the kernel module and stops.
Can anyone tell me how to get it working in either of these
distributions? If not, can someone recommend another distribution where
the setup would go easily?
The system is a Dell Dimension with 1GHz Pentium III and 512MB RAM. The
video board is made by Dell I think, but the reference drivers work fine
in windows, and the NVidia 0.9-2 drivers worked before in Mandrake 7.1
with XF86 4.0.
Thanks,
Kevin

do you stop the network first ?
since you have io and local host interfaces.
mabey read the stuff on multiple netcards.
do you need to pass anything to lilo eg eth0= "0x320,15....."
or simila (example only ) to specify options for your card.
or in /etc/modules.conf ?

I have lpr working fine when it prints to a printer connected to the

I have added the remote machine to the hosts.lpd file on the machine

777 ? 00:00:00 lpd
and all other network communication between the two machines runs fine.
Is there some other place I need to enable this?
