This sounds similar to my problem, which unfortunately I have not yet
resolved. In my case, I found that when I changed the IP address of my NIC,
it did best when I shutdown completely, turned off the power and then
rebooted.
However, what's odd is that my httpd is always accessible to me on the LAN,
but it cannot always be reached from the Internet. Right after a reboot, I
can get in from MSN and AOL without problem. But, after some unknown time
(within an hour), the LAN access is still available but the RH 6.0 box is
unresponsive to Internet-requested http requests.
If Linux were known to suffer viruses, I'd think I had one because the
behavior is so odd. At first, I thought it was security, but why would
security allow access for a while, then stop allowing access?!

You will need a second NIC for the Pentium.
Maybe you try a crossed RJ45 cable to connect.(works only with two pcs)
Then things as you like firewall,smb,proxy etc. on the Pentium

To discover a path mtu, tracepath can be used, it is a traceroute workalike.
You can find it for example in the netbase of Debian GNU/Linux.

I do know now - it's the firewall. The browser uses passive ftp, which
means it tries a port that's blocked.
Public web-access access is only by http, until I decide what to
do about it. And it's finally been registered as nameserver, so

Lets see you just bought a new computer, a Gateway,ok. Has it dawned
on you to perhaps call GATEWAY? They ship linuxboxes, ask them if
that unit can run linux and what flavor. Tell you what, if you use
your head so little on this thing, perhaps linux wouldn't be the thing
for you.

Not sure what distribution you use but this is how I do these things...
1) Try an append line in lilo.conf like
append="ether=10,0x300,eth0" where 10 is IRQ and 0x300 is IO.
2) Check /etc/conf.modules if you used a modulair driver
3) If you have RedHat Linux, try the kernelconfig in XWindows Control Panel

This particular problem is likely due to the S0=1 in the INIT string.
You don't want the modem to pick-up by itself, you want uugetty to
use the CONNECT string to pickup when it detects a RING.
You probably would be better off with mgetty since AFAIK uugetty isn't
maintained and not many use it now. The uugetty I know about also doesn't
support 14400 as a valid baud rate. The baud rates it supports are 2400,
4800, 9600, 19200, 38400, 57600, 115200, and 230400 .

Hello,
Telnet is not listenning on IP addresses it's doing it on port.
Check your configuration file /etc/hosts.allow to see if you allow hosts
from your internal network to login via telnet.
Good luck!

How do you run the sb1kinst.sh?
Now you really hit the nail on the head. ONE of the first problems I had
was doing the isapnp (after the pnpdump). I do a cat /proc/interrupts and
/proc/ioports to see what is available. I then edit my isapnp.conf file and
no matter what I put for io ports I get fatal error. So I read change the
fatal to warning, however I still get errors. I can't even get the pc to
accept the boards ioports. I don't know if I have a compatibility problem
with my pc, it is an old 486 pci, dx100. This was a problem with 5.1 and
6.0. I wasn't sure if I had to compile the sb1000.o kernel(?!) first or if
it had anything to do with my problem. I seem to have every problem
imaginable.
By the way when I do the pnpdump, Everything has # in front. I guess that
is because I don't have any other isa cards. I finally put the card in my
windows 98 to make sure it worked. I had to change the io ports to 0x0110
and 0x0190. The same settings do not work on my linux box.... If I can't
get it to work on LINUX , I don't want it......

Hi all,
I have gotten my FTP server pretty much setup, but am having trouble with 2
parts:
1. When I try to download a file, it gives me the error "file is marked
unretrievable"
2. When I try to upload a file to /incoming my client disconnects. THis
also happens when i try to make directories in /incoming.
I have tried chmod'ing the upload directory chmod a+rw incoming and a+r for
all other files I want users to be able to download, to no avail.
Thanks,
Drew

Not true, at least not true under LINUX.
Under LINUX the same physical Ethernet adapter card can have many
different addresses. You just have to compile alias support into
the Kernel. For instance, I can have one physical Ethernet adapter
with three different addresses as follows:
eth0 = 24.0.187.45
eth0:0 = 24.0.187.171
eth0:1 = 147.183.4.33
eth0:2 = 192.168.1.33
When doing static routing via "route", one just needs to specity the
interface like so:
route add -net 147.183.4.0 netmask 255.255.0.0 dev eth0:1
route add -net 192.168.1.0 netmask 255.255.255.0 dev eth0:2
route add default gw 24.0.187.1 dev eth0

You didn't look too close, obviously. ;-) ncftp actually does
support passive connections - you can either use 'set passive
yes' at the prompt, or put 'passive=on' in your ~/.ncftp/prefs
file. For details, do a 'man ncftp' and enter '/passive'. BTW
I'm using ncftp-3.0beta15 - maybe passive connections are not
supported in older 2.x versions. Get the latest version from:
