Setup your NIC with two IP's. Called aliasing. Should be some good
info out there for that. Also, I have to say that I am impressed.
Mediaone says you can't, Motorola says you can't, but it works through a
hub. I just avoided the hassle all together and used two NIC's but I had
the extra space. Nifty, please post a mini howto when you finally get
the details worked out.

tough question. Since it only happens in one certain configuration, I
would suspect a kernel problem and not a daemon or network problem. In
this case, my recommendation would be to use one of the newer 2.2.x
kernels (7, 8, 9 have all been stable for me). If you really want to
avoid this, then definately upgrade to 2.0.36 or 2.0.37. Other things to
try.
1. Telnet using the same testing strategy you used for ftp. If the
problem reproduces, it is almost certainly a kernel issue
2. Get a newer version of ipautofw. Who knows?
3. Try and reproduce the results with other forwarded ports.
What you wanna do is narrow down the problem giving you a definate
target. I still say "new kernel", but this is up to you. Good luck.

Samba doesn't use TCP/IP for the actual communication part of the
work. It uses a protocol called SMB. You might be able to ping, but this
doesn't mean that you can use SMB. Make sure you have SMB compiled into
the kernel and try again. Read the man page as it describes what you are
doing I believe. Seems to me that you might be having trouble with the
inconsistency between a computers hostname (or IP) and its NetBios name
which are not necessarily the same. The man page goes through this and
provides some hints for using the -s and -c options. Don't know what the
NetBios name of the puter you are conneting to is, but it seems to me
that it wouldn't be 'mount'?! Just some hints. Good luck.

You need to have IP-Forwarding enabled in the kernel. See the other
response as to the solution for that. BTW, if it is slackware, you need
to add this line to /etc/rc.d/rc.local
echo '1' > /proc/sys/net/ipv4/ip_forward (most distros are different in
how to approach this)
Also, if you want to download something that is printing to the screen,
there are 3 options.
1. Hardest. go into Edit|Preferences|Navigator|Applications and find the
offending suffix and remove the helper for that suffix.
2. Hold down shift when you click
3. Right click and choose "Save Link as"
Good luck.

Subject: SOLUTION: Linux 2.2.9 patches broke ISDN?
Date: Tue, 27 Jul 1999 20:08:42 GMT
Somebody finally gave me the tip that made it all work like it should.
The solution was a lot simpler than installing new kernels, recompiling
isdn4kutils and similar. The simple solutions was to issue the following
command before trying to connect:
ifconfig ippp0 up
After that everything seems to work like it should. The person that
tipped me of mentioned that this command should solve the "Network is
down" error message, and that the reason why this was not necessary
before (at least not for me) was that the ippp0 device was up "by
default".
Anyway, everything works like a charm now.

I think you are nuts. How on earth do you do
anything on the net w/o DNS resolution? Every
client out there has to resolve www.yahoo.com to
an ip. You have to provide your clients with
that information for them to 'get out' of your
network with any ease at all. That or you must
be the most hated admin alive.

Hi there,

Hi Mark,

This messages does occour if you receive a ICMP error message to an
packet that was orginated to a broadcast address. The source does tell
us:
/*
* Check the other end isnt violating RFC 1122. Some routers send
* bogus responses to broadcast frames. If you see this message
* first check your netmask matches at both ends, if it does then
* get the other vendor to fix their kit.
*/
So above especially does speak about the case where you have given a
directed broadcast address as destination but the router does not know
this is a broadcast since it does have another netmask. As it seems this
router is directly connected to your network this might be easily
possible.
If you fear the ICMP messages did came from somewhere else you should
install access lists on the router filtering out packets with bogus
source- and/or destination-adresses (called spoofing; e.g. packets
coming in from 206.248.112.72 on the outsided interface).

Wether you are doing something or not is not related. It is only of
interest if your machine does send out packets to an address it thinks
to be an broadcast or not. Programs sending such packets on a regular
schedule are e.g.: SAMBA and timed.

What /usr/sbin/inetd does is to read its configuration file, and watch the
sockets listed therein. When a connection attempt happens on a listed socket,
inetd starts the program associated with that socket (from the configuration
file). The program is then responsible for security and proper port handling.
Commonly, the program run is "tcpd", which reads the /etc/hosts.{allow|deny}
files for security handling. If tcpd finds that the connection attempt is
legal, it runs the appropriate program to really handle the connection (ftpd,
telnetd, rshd, etc.). See the associated man pages (tcpd, inetd, etc) for
more information.
In the case of ping, the ping program sends out a packet and monitors the port
awaiting its reply. So, since neither inetd nor tcpd are involved, there is
no security issue to deal with.

<cont>.......Also The new samba 2.0.5a (which I recommend) you only
have to use:
smbmount //WinBox//share /<mountpoint>
no -c etc anymore

Your problem is 99% chance this:
Your NIC is a PnP whenever you use it with windows it is reset to
exactly that function. In linux it wnats NO PnP sees the card with
driver, but cannot access the PnP mode. Solution:
dump windows or reset that card each time in dos before you boot
linux. You reset the card with the mfr's utility disc.

Too easy (I hope<G>)
You forgot the "" in the cammand line try this:
smbmount \\\\tammy\\c -c "mount /mnt"
I assume that the \\c is actually set up as a share in your winbox.
for complete samba<->WinX setups see:

Date: Tue, 27 Jul 1999 19:36:15 GMT
Yes, in a general sense an interface equates to a net card. It is a
subtle point of TCP/IP that IP addresses are assigned to an interface and
not a machine per se. A net card can have multiple IPs. Each IP in that
situation would address the "interface" between that machine and the
particular "network" that the IP is associated with, even though the
"networks" are riding over the same cable.

I think I have found the problem. It works fine now, if my hosts file includes both
