Yes well that command is nonsensical. "route add -net" attempts to
add a route to a network. By a network we mean a range of 32-bit IP
addresses defined by having a given prefix (which must of course
thereforre be less than 32 bits long). One thing we can be sure about
is that the network prefix can't have a 1 in the least significant bit.
Try:
route add -host 127.0.0.1
Or the preferred command which is:
route add -net 127.0.0.0

What card? We're talking about the loopback device here. The
loopback device is a virtual device - there's no hardware.

You need masquerading. (Probably).

Actually you may be able to use ProxyARP. Iff you have a spare
allocated IP address on the ISP's co-location LAN then you can assign
that IP address to the dialup client and put "proxyarp" in the PPP
options. In this case you should set the IP address of the PPP
interface in the server to be the same as that of the NIC.

Check the /etc/ftpaccess file. Perhaps ftp is configured not to allow
proper user access remotely?
Do you get the same response from the linux box ftp-ing to localhost?
Most ftp daemons are preconfigured to disallow certain users.
/etc/ftpusers is the file for that, I think.

As a sendmail->smail convert I can't comment on qmail but I think the
wealth of documentation available on sendmail means that in complex
situations it's actually easier to set up than smail.

Date: Fri, 16 Apr 1999 19:08:31 GMT
Hi,
I was wondering if anyone had solved this problem, because I am having it as
well. We have an internal network of 10 computers set up with pop3 accounts
using WinX OS. 1 Linux firewall connected via a HDSL to the Internet. 3
portable computers with different ISP using POP3. My Problem is that the
portables cannout email to addresses outside our [EMAIL PROTECTED] It
returns the same responce as Lam states below. We can email each other fine,
and one of the portables does work. So I think it is a setting that I can fix
for the other two, but I'm not familar with linux and SendMail enough to find
the place I need to look.
Any help would take some heat of my back and would be greatly appreated.

Subject: simple gateway function
Date: Sat, 17 Apr 1999 02:20:08 +0200
I installed two ethernet cards to connect two networks.
route -nr tells me:

I am able to ping hosts on the 192.168.2.x net and on the 192.168.3.x
network from the central host (192.168.2.4). But hosts sitting on
different
networks can't see each other.
What gets wrong?
I'm using Linux 2.0.36 and enabled some kernel parameters like:
CONFIG_IP_FORWARD
CONFIG_FIREWALL
CONFIG_IP_FIREWALL
as they seemed to have anything to do with routing, although we don't
need any firewalling.
Do we really need some routed now? or something else beyond ifconfig
and route add -net ...?

Hi,
I have an IBM Auto 16/4 Token Ring card (PCMCIA). I am not sure if this
also works
with the Turbo but you should give it a try. The card will only work
when you disable the high memory area for PCMCIA devices. Under RadHat
5.2 the high memory area is active by default, os maybe this is your
problem... .
Try to edit your /etc/pcmcia/config.opts and comment out or delete the
high memory area and you card may work then.
#
# Local PCMCIA Configuration File
#
# System resources available for PCMCIA devices
#
include port 0x100-0x4ff, port 0x1000-0x17ff
include memory 0xc0000-0xfffff #, memory 0xa0000000-0xa0ffffff
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
Good Luck!
Guenther.

Date: Sat, 17 Apr 1999 00:28:48 GMT
If I try to make a POP3 connection to my Linux box (Redhat 5.2) the
connection fails. Trying to get in with Telnet to port 110 fails too.
It seems to timeout. Sendmail itself appears to be working, the pop
user's account is "enabled" in linuxconf, mail sent to the user's
account gets placed in the user's mailbox, there are no restrictions set in
/etc/hosts.deny or hosts.allow
Can anybody think of anything else to check?
Thanks in Advance

If there's any difference then the built-in driver has to be better.

Subject: Samba-network drives read only
Date: Fri, 16 Apr 1999 20:33:48 -0400
I am setting up a home network with a Linux server. Samba is running great
with the one exception that my network directories are read only for any
user but root. I have the following in the smb.conf file for the
directories I would like any user to access:
[public]
path = path to directory
public = yes
writable = yes
printable = no
My Windows machines can access the directories without a problem, but I must
create a "root" sign-on to write to the drive. I have tried both
"writable=yes" and "read only=no" but still get read only access for all
users but root. I'm sure I must be missing something simple (I've been
using Linux about two weeks) but I'm ready to rip out my hair. Any help
would be greatly appreciated.

Reply-To: [EMAIL PROTECTED]
Hello,
for a new server I just installed SuSe Linux 6.0 ( AMD K6 350, 256MB,
GDT Raid 5 30GB, tulip NIC 100MBit) and have a severe problem
connecting through the lan:
It is not possible to ping, from/to my linux server. Ping/Telnet from
another Computer don't work, too.
Now I try to debug, and when I start "tcpdump -i eth0" on my new
server, everything works fine, everything works. But when I press
Ctrl- C to stop the tcpdump, it's all over... Nothing works any more.
All remote x-windows are dieing, telnet disconnects etc.
I don't know, what's going on... Why do I have to start an "tcpdum -i
eth0 >/dev/null&" to work with the computer?
Thanks a lot
David Kirschey
PS: After an amount of time "tcpdum -i eth0 >/dev/null&" fails with an
"Segmentation error". But the network still works...

A "client" is not a "protocol" also, the MS Client for networks operates on

Hello,
I have a Problem with the WWW- Access using Squid (SuSe 6.0).
Config 1 (without Squid)
1. Start netscape&
2. There in Proxy Config I enter the Proxy and Port (8080) of my ISP
3. Select a Internet Site (e.g. www.linux.org)
ISDN is dialing up and everything works.
Config 2 (with Squid running)
1. Start netscape&
2. There in Proxy Config I enter the Proxy and Port of Squid
(localhost)
3. Select a Internet Site (e.g. www.linux.org)
ISDN is dialing up but after a few seconds squid ends with an error
message ("Remote Server is down" or so)
I did not find, where to enter my ISP's proxy in, too (but this is not
so important I hope).
Maybe it's a small problem. Do you have an idea?
Thank you for any suggestions.

I seemed to be able to connect quite well via freenet.co.uk, as I usually use
virgin, so I'd have this as a second logon.
I'm using 08453530000

It seems to run lots faster than virgin at the moment!

If the latter is what you mean then you are seeing exactlly what
