Hmm, I *think* that appletalk is an alternative to TCP/IP, and won't
run over it, but may be wrong. You'll need to mount the disc via NFS.
Again, I might be wrong on this though, I've looked into doing
something similar and after the little bit of investigation I've done,
I sort of got the above impression.

Oh this is WEIRD!! The ftp problems only happen against ONE SERVER.
I'm on home.com (TCI Cable-Modem service). Our "free" website is at
members.home.com, and the login banner looks like:

Ok, so is it a wu-ftp server problem? Ok, tried a Microsoft server,
works fine. Tried wu-2.4(30) (ftp.std.com) and that worked OK.
Wu-2.4(1) on a 1.2 kernel Linux box (206.242.78.2) worked OK.
sunsite.unc.edu is also using wu-ftp (but doesn't tell the version).
That works OK.
So what is members.home.net? Can't readily tell. Connection refused
for telnet, smtp, rcp, etc.. And I'm not going to port-scan my ISP.
Summary: Cannot FTP through a masquerading box to one particular
server.
Calling my ISP isn't an option. We're only supposed to be running
Windows or Mac boxes, and they'd hang up on me once I started
explaining what's going on...
Any clues?

The route at the other end of my PPP connection will not respond to pings
either.
But my link is good. Try pinging something else, like their DNS server.

Subject: smbmount must be installed suid root
Date: Mon, 15 Feb 1999 08:17:41 -0600
Just installed SuSE 5.3 and am getting the following error message when
doing smbmount:
smbmount must be installed suid root
This only happens when doing the mount as a normal user. All goes well
when done as root.
I am using the same smb.conf file that worked successfully for me just a
few days ago in a Slackware installation. I tried uninstalling and
reinstalling the samba package (using YaST), but that didn't help.
Here is the output from ls -l /usr/bin/smb*
-rwxr-xr-x 1 root root 239290 Aug 4 1998 smbclient
-rwxr-xr-x 1 root root 10244 Aug 4 1998 smbmount

Anyone have any ideas?

Get out of Windows' reboot-every-five-minutes mode of thinking.
Just write your script to down the network interfaces and routes and
reconfigure your system using the configuration you want, then restart any
IP-address-dependent daemons. There's no reason to reboot to do this.

Not everyone is as lucky as you. It's possible that he made it
overcomplicated, but it's also very possible that you've
oversimplified. He probably does not have the same hardware as
you. In fact, I have heard of people having problems with a
similar driver to the one he mentioned. RedHat doesn't have
support for EVERY network card under the sun - and that's why he
had to get it from the hardware vendor, probably.

You will notice that you did not remove comp.os.linux.networking from
your reply. If you don't like his post, you're not required to
reply to it..but please don't scare other newbies away with a
holier-than-thou attitude. If you didn't mean any offense or
hard feelings, than I'm sorry to reply this way...but you did
come off as sounding like you were downright angry at him.
The original poster, although he didn't provide enough information,
does not deserve to be crucified like that. He DID look elsewhere
first, and you gotta give him credit for that. I'm no guru, and
constantly receive help from the linux community, and it's really
damn cool how everyone's almost always nice..let's try to keep it
that way.

We'll probably need to see the chat and pppd connection scripts you are
using, sans any password. The appropriate messages taken directly from
/var/log/messages would help too. Add the pppd option debug and look
for ppp negotiation messages, hopefully in /var/log/debug - although
you may not be reaching this stage.

Is the NT machine's name (fully-qualified, if you're running DNS)
in the /etc/hosts.lpd file? On some versions, you could use wildcards
for portions of hostname (e.g. *.somedomain.org) and have the thing
work. Some versions don't let you do that and you need an entry of
"NT.somedomain.org" in there.
Note that for this to work gracefully, the NT box must have a valid
reverse IP mapping. This, of course, gets very sticky when you have
a large number of dynamic IP machines and no reverse (in-addr.arpa)
mappings. Another way might just be to get rid of the check in the
source code and recompile.

Subject: Squid cache chained to NT proxy (help!)
Date: Mon, 15 Feb 1999 11:53:23 -0500
I've got a squid cache (on a linux box) running wondefully in an
elementary school (with a 56k line) bu now I want to connect/link it to an
NT cache/proxy in a different building (which does my Surfwatch filtering)
and I can't get it to work.
Is anyone else doing this?
I've tried a bunch of variations of
cache_host my.nt.server parent 80 7 default
(80 is the port I point a desktop to on the NTG box if I want it to
filter) but it just doesn't filter.
Any suggestions? (Any suggestions on where to look for more info?)

SYN flood protection
CONFIG_SYN_COOKIES
Normal TCP/IP networking is open to an attack known as SYN flooding.
This attack prevents legitimate users from being able to connect to your
computer and requires very little work for the attacker. SYN cookies
provide protection against this type of attack. With this option turned
on the TCP/IP stack will use a cryptographic challenge protocol known as
SYN cookies to enable legitimate users to continue to connect, even when
your machine is under attack. If you are SYN flooded, the source address
reported by the kernel is likely to have been forged by the attacker.
The source address is reported as an aid in tracing the packets to their
actual source.
