its not just a linux problem, I tried using the same card on both, a linux
machine and a win98 machine. the card, simply put, sucks. linksys made its
name by producing 16-bit cards for win 3.1 and has rested on its haunches
since. My advice would be get rid of the card, and spring for the $30-40
(unless you go 3com) on a new 100baseT card.

Which version of dhcpcd are you using? The 0.70 version does not work with
the 2.2.X kernels.
If you are using a correct version, do your logs tell you any other things
like is there DHCPOFFER messages being recieved?

Subject: dhcp and 255.255.255.255 a new twist
Date: Sat, 17 Apr 1999 10:08:01 -0600
I have configured dhcpd on a RH 5.2 box with three network interfaces.
(Don't ask, that part is a long story.)
DHCP correctly sees the inbound interface and assigns an address
apropriate for the inbound subnet.
It then needs to respond to the client sending to broadcast address of
255.255.255.255.
The problem, the routing code wants to send this address out one
interface. (Actually loopback always gets a packet also) It needs to go out,
as a minimum, the inbound interface, or lacking that, all three. If I enter
three route commands the machine selects one of the three (usually the one
that the default route is one) and sends it there.
The question, is there a way to make a linux machine flood a broadcast to
all interfaces.
Thanks in advance

I had exactly the same problem. To solve this remove the

Whcih version of dhcpcd are you using? There is a bug in the 0.70 version
most people are using now that causes the DHCPREQUEST message to be
encapsulated as a BOOTP rather than a DCHP packet. If your DHCP server is
on a different subnet than you are the router is probably configured as a
forwarding agent and will allmost certainly drop the DHCPREQUEST (since it
is BOOTP) and your server never sees the request.

Hi,
I have a question which i can't seem to find answer.
i've setup an amd k6-2 333MHZ cpu with 64MB ram and 6.4GB IDE harddisk
(UDMA)
the network is running 100MBps, and runing as a file server using samba.
how many max users can this setup take ??
What if i setup web server, internal email server (smtp and pop) and gateway
to the internet on the same box, how many user can it handle now ??
btw, my internet acces is thru a 56kbps dial-up modem.
Thanks in advance for answers.

There are many people -- like me -- that are tying them together using perl
scripst but AFAIK it is not yet built into dhcpd. Version three is
supposed to do this.

In my case, because that is how I receive mail from my ISP. In your
case, maybe the same, maybe because someone is trying to send you mail
direct, maybe its your own mail going *outbound* and maybe, maybe it is
a spammer trying to relay mail. Without seeing some of the logs I
couldn't really say. Mail some if you like. /var/log/maillog normally.

Well. IIRC, an incoming request [getting info from you] will originate
from "any old port" and come into your IDENT port, whilst an outgoing
request [wanting info from elsewhere] would start from your [any old]
port and go to the other machine's IDENT port. So I suppose you could
firewall off any access to your own IDENT port. How this might affect
other things I don't know. You could also comment out the "auth" entry
in /etc/inetd.conf and restart inetd if it bothers you. Then noone can
request stuff from your machine. (Sendmail will still work.)

Newsgroups: alt.linux.slakware
Subject: NFS WITHIN AN IP MASQ FIREWALL
This may be an orriginal question and any help would be very much
appreciated.
Here's my situation. I'll draw a mapped diagram at the bottom to further
explain.
I have several machines connected within a LAN, and connected to the
outside internet using a linux box running IP-masq ( NAT )
The machines inside my lan, all run linux as well.
I am attempting to mount via NFS, to a machine on the outside internet.
The NFS server on the outside has, in it's /etc/exports file,
the ip number of the machine on my end, which is hosting for ip-masq
as rw,no_root_squash
I am able to successfully establish an NFS mount from my ip-masq box, to
the box which I wish to mount to.
Now... When I attempt to do a mount from within my ip-masq LAN, to the
same machine on the outter internet, it attempts a connection to
the outter machine, but the connection is refused by the outter machine,
due to the fact that ip-masq is assigning it an Illegal Port number.
I note this by the /var/log/messages file from the NFS Server which reads
NFS from xxx.xxx.xxx.xxx on ILLEGAL port number.
Here's a diagram ( I do better at most other things, but not well at
diagrams )
Inner Lan Machines
ipmasq box X <--trying to estab.
OUTTER NFS SERVER _____ | nfs to outter
|---|_____________________| |__________________| from these boxes
|---| |_____| |
X <---
If there was some way, I could convince NFS to assign say
perhaps ( and I'm guessing port # 2048 ) then I would be able
to connect from within the ip masq LAN to the outside.
Has anyone come across any solution to this.. or better yet, has anyone
been crazy enough to attempt this yet ??
