Date: Mon, 15 Mar 1999 20:37:14 +0800
Hi,
Anybody got a Teles 16.3c ISA PnP ISDN card working with
Linux kernel 2.0.36??
I've compiled the ISDN subsystem as a module...
HiSax drivers as modules... here's the relevant section in
the .config file...
CONFIG_ISDN=m
CONFIG_ISDN_PPP=y
CONFIG_ISDN_PPP_VJ=y
CONFIG_ISDN_MPP=y
CONFIG_ISDN_DRV_LOOP=m
CONFIG_ISDN_DRV_HISAX=m
CONFIG_HISAX_EURO=y
CONFIG_HISAX_16_0=y
CONFIG_HISAX_16_3=y
CONFIG_HISAX_TELES3C=y
CONFIG_HISAX_TELESPCI=y
CONFIG_HISAX_S0BOX=y
Booted with this kernel... got isapnp to load the following isapnp.conf..
(CONFIGURE TAG2620/209717183 (LD 0
(IO 0 (SIZE 2) (BASE 0x0300))
(INT 0 (IRQ 10 (MODE +E)))
(NAME "TAG2620/209717183[0]{TELES.S0/16.3c Plug&Play}")
(ACT Y)
))
ran isapnp and got ...
Board 1 has Identity 76 04 03 02 01 00 20 32 0d: CIR2000 Serial No 67305985 [checksum
76]
Board 2 has Identity bd 0c 80 07 bf 20 26 27 50: TAG2620 Serial No 209717183
[checksum bd]
TAG2620/209717183[0]{TELES.S0/16.3c Plug&Play}: Port 0x300; IRQ10 --- Enabled OK
BUT when i tried to load the HiSax modules by modprobe... i
got the following errors...
# modprobe hisax type=14 protocol=2 io=0x300 irq=10
Initialization of hisax failed
Initialization of hisax failed
ISDN subsystem Rev: 1.44.2.9/1.41.2.11/1.48.2.27/1.28.2.2/none loaded

Teles 16.3c: IRQ(10) getting no interrupts during init 3
HiSax: Card Teles 16.3c not installed !

What could be the problem? any ideas?

I (foolishly) used Debian apt-get upgrade to "upgrade" my system. The
upgraded system now has no diald capabilty because diald stopped working
imediately after I did this :(
It seems that it's getting to the point where it should negotiate
IP addresses but then it just hangs and I get errors back relating to
/sbin/route (see below). Does anyone know what I need to do to fix this?
I've checked the stuff about checking hostname returns the short name
etc in the FAQ. I'm out of my depth.

Date: Mon, 15 Mar 1999 13:46:04 +0100
Can't seem to find that FAQ anymore on setting up a Linux local network
step-by-step. If I remember correctly it was on some server in Australia.
Who can help me out here?
Want to use RedHat 5.2 to create a Linux server, connected to the Internet,
with both an NT workstation and a Mac PowerPC as clients (both of them being
able to access the internet through the Linux server).
This specific FAQ described the hardware I would need to do this, plus of
course the software side of it.
Appreciate any help, but would also benefit from some suggestions on
additional reading stuff.
Thank you,

You have to make sure that IP forwarding is enabled in your kernel.
Also, you have to give it masquerading rules.
Did you do all that?

I didn't ask if your machine has two NIC's in it. I got caught by that when
eth0 became the wrong card. When probing, linux starts at low IO ranges and
works its way up. Setting eth0 to 0x300 and eth1 to 0x320 solved that little
problem.

Hi there...
I'm currently working on a very simplified NFS server in Java, which
will not really be an common NFS server, but which will use the NFS
protocol to share a web tree (I know, it's not really clear ;-)
I would really need some help and some explanations on the way the linux
NFS server is handling the file handles and the cookies on directory
listings. So could you point me to a maybe more specific mailing list,
or directly to somebody who may help me (already tried Olaf, but still
no answer.......)
Many thanks in advance, and best regards... - Patrick -

I'm having trouble with NFS.
On my NFS server I'm running portmap, mountd and nfsd and I have changed the
/etc/exports to share / to everybody with root privilegies and write access.
On my second computer I mount the shared / but I can't write anything and I
don't even see any files when I'm looking in users home directories.
What am I doing wrong?
Any suggestions welcome...

I suggest you install a proxy server on the linux box, a perfect is
squid(www.squid.org), it sould come with RH5.2. A proxy lets your
clients request http pages to the linux , and this one forwards the
response to the clients.It's the best solutions to give clients access
to the net.

Have you enabled IP forwarding on the Linux box? Your configuration would give
you the symptoms described if Linux IP forwarding were disabled.

I found this message in my messages logfile, and there was no entry in the secure
logfile:
Warning: possible SYN flood from 203.66.112.135 on <MY IP ADDRESS> Sending cookies.
I'm guessing someone tricked my Linux box into sending out my cookies. The IP address
it came from has no entry in a Domain Server, so I dont know where it came from, but
the
guy is running RH linux and has Apache running on his machine. (http://203.66.112.135)
So, can anyone tell me anything about this, like:
1) What is a SYN flood?
2) How did he steal my cookies?
3) How do I stop it?
Also, if my machine did send cookies, which cookies did it send? There are a
different set
of cookies for each user, and you'd have to know the user name, right??
Thanks for any info...
