Whatever rights you grant a user will be in effect. Restrict them to the
anonymous user, and the default setup will contain them in the ftp tree.

and connect with a client, browsing is only possible for a few seconds and
sites, then squids stops with following error:
FATAL: file_write: bad FD
Aborted
or sometimes with:
FATAL: storeUnlockObject: bad swap_status

sometimes squid fails to start at startup, sometimes not (i start it with -D

this is really a problem for me, since the server has to be ready until
thursday...
if somebody could help, please email or post in this group.
i have suse linux 6.0, kernel 2.0.36

Hi
Im curious if anyone has had any experience using linux with the @HOME
cable modem service (www.home.com).
I know they do not support it, but is it possible to connect anyway and
do they fire wall? static or dynamic ip? Is the general performance of
the line good or bad?
I'd plan to run a web server and maybe a mail server over it (for
completely personal use of course). Anyone have any experience with them?
Thanx in Advance

Subject: SQUID2 Problem: no route to host
Date: Wed, 12 May 1999 11:22:44 +0200
Hi all,
Recently i upgraded my squid1 to squid2, but i'm not able to find out
how to use the rules inside_firewall (which appear in squid1) inside
squid2. I've been looking in the manual on the home-page, deja-news
etc.. Can someone point me to a url which gives a descent discription of
these rules?
If not, here's my problem:
I configured squid to use my isp's proxy as an parent, but for some
reason i don't get outside the domain of my isp. This is not a hardware
problem, nor a problem whith icp, nor whith routing in general!!! When I
use the proxy of my isp directly everything works well.
I'm sure this has something to do with the firewall, because when i use
squid1 i've got the rules inside_firewall and such.
This is how my network looks: 192.168.0.0/255.255.255.0
This is my ISP's network: 10.0.0.0/255.255.255.0
squid and firewall on: 192.168.0.1
btw: the firewall on this machine is working ok, I can do everthing i
want to do, except using squid2 :(
Any suggestions are welcome,
Greetz,

John, you need to recompile your kernel for the PCI card. I assume that
you did this already for the ISA card and the procedure is exactly the
same. Under the network cards, there is a choice for PCI cards and you
will find the NE2000 driver there :)

I've been having some problems with a redhat 5.2 box. It is a p166
with a 3com 3c905 rev b nic. I have a adsl connection running dhcpcd
0.7. The box works fine for a while and then suddenly I get errors
such as these in the log file.

May 9 00:53:45 localhost kernel: eth0: Setting promiscuous mode.
May 9 00:53:45 localhost dhcpcd[161]: no DHCPOFFER messages
When this happens I loose all network connectivity. I am not able to
telnet into, ping, or etc. the box. I can log in from the console
though. After a shutdown and reboot the machine will work fine until
this happens again. The time between incidents ranges between a few
days and a few months.
My question is, what is most likely causing this? I don't think that
it is the DHCP server, since I do not have this problem with other
machines on the same network. Could it be a faulty nic?

Of course I know that I ought to use chat, and that is what I started
with. When the line deteriorates, chat is not too forgiving on my
lousy phone line. Maybe, there is some way to tweak it, but I haven't
quite figured that out. Sometimes, chat can try to connect for 30
minutes or more (at times an hour continuous) before being
successful. I'm talking just plain negotiation over the phone line,
haven't even reach ppp yet (and due to poor line conditions, 7-bit
unclean situations are pretty common).
I realized the problem when I found out that it seems to connect on
Win98 and also Linux 1.0.2 (I know that is ancient) and Win 3.1
on my old 486 without too much difficulty, and so I suspected
something to do with the negotiation. So, I searched and stumbled upon
minicom as an alternative. I have heard that kermit can also do that,
but haven't tried.
minicom, on the other hand, has more than 90% success for
me. So, until things improve, I have to stay with ppp over minicom.
Not the best approach, but works reasonably well for me (afterall that's
what Linux is all about... so many different ways to do the same
thing... choices).
Thanks.

Subject: Serial Monitor
Date: Wed, 12 May 1999 08:52:46 GMT
After trekking through Dejanews for most of last night and only finding
hints as to how to do it, I think I finally see how to implement a
serial monitor but if I could just run it past you, I'd be grateful.
My setup at the moment is that I have a single client PC with monitor
etc on one side of the room, on the other side, hidden behind
bookshelves etc are 2 other headless PCs one's a mail server/firewall
etc, the other is a big database etc server box. All machines have
graphics/network cards etc, just no monitor attached. The problem is
that whenever I upgrade or have problems booting etc, I end up having to
turn the living room upside down to get the machines to a monitor or
vice-versa. What I'm really looking for is some means of remotely
administering them without all that hassle (At present I use telnet,
whcih is fine as long as they've booted correctly).
As I understand it, I should be able to connect the client machine to
either of the servers via their serial ports, define /dev/console on the
server to be /dev/ttySwhatever and somehow connect Seyon to
/dev/ttySwhatever on the client machine and be able to remotely
administer the server.
Is the above correct? Or am I on entirely the wrong track?
Thanks
Pat.

John,
You may need to tell the Linux kernel to probe for both NE2000 cards at
startup. Normally, the kernel probes for only one. You can do this by adding
a line into your /etc/lilo.conf file which reads as follows:
append="ether=0,0,eth0 ether=0,0,eth1"
This line means to autoprobe for two ethernet cards. Or, more generally, you
can use:
append="ether=IRQ,IOADDR,eth0 ether=IRQ,IOADDR,eth1"
if you know the IRQ and IO addresses for both your cards. Be sure to run
/sbin/lilo after you do this.
For more info, visit the Ethernet-HOWTO at
metalab.unc.edu/LDP/HOWTO/Ethernet-HOWTO-10.html

I have got similar problem, but both machines are Linux boxes. I got my

my problem was very different from you, I got 1 10/100M and 1 10M

try a ftp-serverprogram with a user-db like proftpd. there you
can configure users a way that they can only see the contains of
