Sure. That is how licenses work. Once you have a licensed copy, well,
you have one :-)

Same for me. At least on boot before the modutils updated rpm It just
didn't load any modules and was alright. I update a few packages like
people tell me and the system becomes a mess won't function at all. I
had to reinstall from scratch and now I ain't messing with it until I
can get some concrete answers to what you absolutely need to upgrade for
RH 5.2 to work with this kernel.
No I couldn't get the modules to load. Tells me it can't find them but
they were right were they were supposed to be /lib/modules/2.2.0-pre6
By the way I am running a Stock system. RH5.2 with everything loaded
from install CD.

Yes, but if you have to do this configuration to even get started
what have you gained from the configuration facility? If you
are using DCHP the server can give you the IP address, default
router, DNS server, and domain name automatically. At that point
you would be prepared to make a network request to some
well-known DNS name (or alias) and service for a hands-off
startup. As long as you actually have a DNS server available
you will get a connection or an authoritative response that the
name doesn't exist immediately. However if your DNS isn't
available there is a fairly long timeout.

Have you tried connecting without using masq? I could be the server to
which you are connected in addition to your local masquerading kernel.

I believe there's something like this in OSS. I saw a "Virtual Mixer" thingy, and in
the docs it said it was for doing real time mixing of multiple sound sources, so you
could do exactly as you're thinking.

Wrong on most accounts. const Foo *foo; and Foo const *foo; mean the same: foo
being a pointer to const Foo. const Foo const *foo; would mean the same but is
illegal (double const). You are confusing this with Foo * const foo; and const

How can I create a device like that? Multiple processes are supposed to
write to /dev/leaf at the same time while internally the audio mixer
must handle all connections separately. It looks like a kind of named
socket to me, but can this be made compatible with the original
/dev/dsp behaviour? I'd prefer a userspace solution here. Mixing the
audio data shouldn't be a big problem.

I would like to compile my kernel with a 4 megabyte cache size instead of the

can glibc2.0 be seamlessly upgraded to glibc2.1? i have glibc-2.0.7
(actually .6 pre-something with redhat hacks), if i install
glibc-2.0.109 from rawhide, will all my dynamically linked programs
continue to work? or is this a major jump like libc5 -> glibc2
requiring a total system recompile?

IP masquerading in 2.0 will remove an entry after 15 minutes if it
hasn't been used. So idle time kills the link.
ssh uses keepalives to try to keep the connection live. Ironically,
the keepalive threshold in Linux is also 15 minutes, and it's just not
quite good enough. I submitted this as a bug to the masquerade people
(suggesting they set the default timeout to a few minutes over the
keepalive interval), but I never got any response.
You can set the masquerade timeout to something higher with ipfwadm.
I do this:
# set the masq timeout to 20 minutes for TCP, 5 minutes for UDP
$IPFWADM -M -s 1200 120 300
In Linux 2.2, this is all different.

I don't know what you mean by "without using masq". With two computers, one
modem, and an ISP that hands me one IP number when I dial up with ppp, I
don't know how to get both of them on the network without using IP
masquerading. And it works fine. Except for the expiration time.
I also don't know what you mean by "I could be the server to ...", sorry --
it sounds like you're offering to be part of my modem setup, so it must be a
misprint.

Date: Tue, 12 Jan 1999 18:20:48 GMT
All,
I apologize if I haven't included enough detail on the following issue,
but I will be happy to provide more info as requested.
I have experienced frequent system hangs when running sox to play au
files. I first experienced this in 2.1.131 and it still occurs with
2.2pre6.
The system:
Dual P233MMX on a Tyan Tomcat IV
Adaptec 2940 (no IDE) using md in a RAID0 configuration
TI Thunderlan NIC
Dual Matrox Millenium
SoundBlaster 16
In testing, I found that the sound card doesn't seem to make a
difference. I recompiled the kernel with Opti card support, installed
the Opti and had the same results. There are no IRQ, DMA or IO mem
address conflicts with either card. Last night I recompiled without SMP
enabled, and it was stable. I can freely recreate this problem with the
SMP kernel, so if anyone can help, I would be happy to provide any
details requested.
Thanks in advance,
Jay
