Samba and ftp are two seperate "utilities". Your Samba setup
should have no effect on ftp. Have you setup /etc/ftpaccess,
ftphosts etc. See man ftpaccess, NET-3-HOWTO. What specific
error messages are you getting when you ftp?

I posted this question several times last week on this newsgroup.
The question was how to receive external X-window clients through
a firewall running IP masquerading and forwarding. No-one could
answer the question.
I just solved the problem using IP Port Forwarding (ipportfw). I know
that other people were interested in this.
See the ipportfw website:
http://www.monmouth.demon.co.uk/ipsubs/portforwarding.html
I used the following syntax:
ipportfw -C
ipportfw -A -t $ROUTER_IP/6000 -R 10.0.0.25/6000
ipportfw -A -t $ROUTER_IP/6001 -R 10.0.0.25/6001
...
ipportfw -A -t $ROUTER_IP/6019 -R 10.0.0.25/6019
where $ROUTER_IP is the external IP address of my firewall.
You will need to patch the kernel and re-compile.
X-windows uses port 6000 to start, then uses 6001, 6002, etc.
for each window that it opens.
It works great!

You did not say so I'm guessing you are using smbclient as it
looks like your mounting an NT disk from Linux. It works that
way by default.
If your using smbmount then it works that way also. -P is only
provided so you can give the password on the command line so
scripts will have a way to work without intervention.

Subject: does linux like WINS?
Date: 2 Mar 1999 23:25:45 GMT
hello all. i have greatly simplified my network in an effort to add my
linux server to my windows network. the linux box does appear in the
network neighborhoods of the win 9x/nt4 workstations. i can ping and telnet
to the linux box by name and by ip address from all workstations. i cannot
ftp yet, but i suspect that is because i have not set up ftp correctly on
the linux side yet.
my bigger concern is that the linux box (192.168.34.6) does not seem to be
querying the WINS database on my NT3.51 server (192.168.34.1) correctly. i
cannot ping the workstations by name, only by ip address. since the
workstations receive ip addresses dynamically from DHCP on the NT server, i
do not know which ip address corresponds to which workstation unless i look
it up in the WINS database, or go to each workstation to determine it's ip
address using winipcfg. that being the case, i cannot simply add all the
workstations on my network to /etc/hosts. i have added the following to my
/etc/smb.conf:
wins server = 192.168.34.1
name resolve order = wins hosts lmhosts bcast
but it doesn't seem to be working properly. am i missing something? i've
heard that linux may not "like" WINS. is this true? i am using the Red Hat
5.2 distribution (kernel 2.0.36-0.7). should i consider setting up my linux
box as the WINS or DNS caching server for my network?
thank you for your attention in this matter. any feedback would be very
welcome. if you'd like to respond directly to my email address, remember to
remove NOSPAM from the reply address.

For ICQ you need Port 4000 UDP. Configure your ICQ to use a firewall and
specify the port range it should use.

I beleive both SuSE and Slackware comes with diald which will do dial on

their diald package on redhat contrib site.

I am using SMC PCI-NIC. In auto probing it finds it irq 11 and address
0xe800 hich matches
with win95. If I run ifup it's giving delaying eth0 initialization. I am
using smc9194 module. If
I use ifconfig then
SIOCSIFBRDADDR
eth0 : interface not found
I am desperately trying to make it work.
Initially it was giving at the booting time smc9194.o: init_module the
device is busy, delaying eth0 initialization.
But now it is not giving any messages like that but it is not loading
the module. But PCI is picking up the card
correctly. Can anyone help me out from this place.
note : my card is also ne2000 compatible. Shall I try to load ne2k-pci.o
module with IRQ 8 and base address
0xe800. I haven't try this option.
Thank you in advance,

newbie problems.
I've got RD5 with win95, i guess i figured out the partitioning bit.
But is my back and forth rebooting hard on the computer?
And what would be a great help is, if I could get connected to the net.
I'm hooked up through my university which doesn't have online help.
When in x-windows and doing netcfg I'm not sure what to put where.
It's PPP i'm trying to do and have the dns info i think, i can get win95
hooked up anyways.
help, thanks jullian

Well, I guess I meant just check it to make sure it was still set to
what you think it should be. Stopping named should have not stopped
your name resolution from working, since you are not pointing to
yourself. What happens when you run nslookup interactively, ie, with
no arguments? Can you resolve anything? Like this:
[xcitor@axel xcitor]$ nslookup

This information is not likely to be of any use. If rlogin works, then
typically the .rhosts is of the correct format as is /etc/hosts.allow etc.

You mean the host id, which is held in NVRAM, (which can be modified),
which was designed to allow licensing of software, rather than the
tracking of the person who was using it.
The fact is that host id's existed a longtime before the Internet
went "mainstream". Given the current rate of "dumbing down" of
functionality, it is only a matter of time until this "host id"
techology gets misused.

Bingo - almost! What you describe is where I want to be ultimately.
But right now I don't care about WinGate, etc... because I can't even

If the serial port is plugged into a TCP/IP-Aware computer (i.e. Linux), you
could telnet to that computer and use a terminal program to access the
serial port...
If it is not connected to an IP-Aware computer, then you will need to get
some sort of hardware which will do this translation.
An alternative to the first situation might be to create some sort of tty
loop between the Serial tty and the telnet tty - I've never done this, but
it might enable you to avoid giving an account shell access and having to
run Minicom...
I believe the WindowsModem sharing mini-HOWTO might help with this - it
talks about linking tcp/ip ports to Serial ports - however, there is no
security there unless you use SSH or something similar. Below is a script
which I put in the file in.modemd:
#!/usr/bin/perl
select((select(STDOUT), $| = 1)[$[]);
select((select(STDIN), $| = 1)[$[]);
exec 'cu -s 115200 -l /dev/ttyS1';
die '$0: Cant exec cu: $!\n';
I added the following line to inetd:
modem stream tcp nowait root /usr/sbin/tcpd /usr/sbin/in.modemd /dev/ttyS1
and added the 'modem' service to /etc/services:
modem 2006/tcp modemd
Note, though, that this doesn't use any security!
As for having access to many serial ports, you could have multiple modemd
services on different ports linked to different serial devices...Or, if
you're good with perl, perhaps you can script something better!
