We had a situation like that a while back. The simple
solution was to replicate the passwd files for the two machines
so they both use the same UID's (it did require us to write
a script to get them in sync) -- then we didn't have any problems.
The other gotcha was Solaris can assign big number USERids,
which are intolerable to 5.2 -- we had to go in an reassign a bunch
of those.
But with the same password/shadow files it should work just
fine. You have to be a bit careful with some of the systems IDs,
since they map differently in Linux/Solaris -- but it seems to work
fine.
Best regards!

Is it possible (Redhat 5.1) to set up multiple static IPs on
a PPP interface? I am in the middle of a network renumbering
and need to temporarily have both networks connected. The remote
router knows about the networks, but I need to know how to configure
additional addresses for the same PPP interface. Under Solaris
it would be easy... but Linux? Anyone? E-mail responses
preferred...

Subject: Re: Identd -- necessary?
First off, if you were looking at /etc/inetd.conf, it would be named
"auth", calling /usr/sbin/in.identd. identd is an identification daemon
that runs in the background, on port 113. It is used to identify
usernames.
If you use IRC (Internet Relay Chat), most servers requre that you have
identd installed & running. It is also used to identify you to some
servers. Say you are logged into your box as root on console 1. You
telnet into www.yahoo.com, port 23. If yahoo admins were to check their
logs, they'd see the connection to port 23 came from [EMAIL PROTECTED]
Pretty simple.. go read an RFC or something (http://www.isi.edu). =)

Hi again Tom..
Thanks for the sample file. I will give the bridge mode a try. As you can
tell I am a newbie at Linux and a little lost. So you are saying that you
can use bridging with Linux with the router connected to the ethernet card
in the Linux box ?
When I read that ping,trace, telnet and web interface is disabled in bridge
mode, I assumed that I could not use any of the above functions through it.
Obviously I want to be able to telnet and ping other places. If I understand
you correctly, these functions can not used internally on the router ???
But, will still be able to ping.microsoft.com and telnet other sites on the
web?
In netcfg do you have to add anything to the routing area, or is all your
settings contained in the eth0 configuration area ? I read somewhere that
when using NAT the router has an IP of 10.0.0.x. Does this sound right and
do I need to add this to my routing area.
Thanks for all your help.
Regards,
Rich

Subject: Sharing ppp0 to eth0 : Ping - Request Timed Out
Date: Fri, 25 Jun 1999 02:48:55 +1000
I am a new user in Linux
Currently I want to setup a ppp connection with my Linux and share this
connection to the LAN.
I got three computer, two of them running Windows NT and the other
running Linux Red Hat 5.2
I establish my ppp connection using the following command!
pppd connect 'chat "" "ATX3" "" ATDT12345678 CONNECT ""
ervice? ppp sername: hi word: hello' /dev/cua1 115200
Then I check the connection status using the ifconfig command.
If return a ppp0 connection with two address to me
inet address: 202.100.56.124
P-t-P: 202.100.56.13
I use the P-t-P address as my routing address with the following command
route add default gw 202.100.56.13 ppp0
My routing table is below
202.100.56.13 0.0.0.0 255.255.255.255 UH
1500 0 ppp0
192.168.0.0 0.0.0.0 255.255.255.0
U 1500 0 eth0
127.0.0.0 0.0.0.0
255.0.0.0 U 3584 0 lo
0.0.0.0 202.100.56.13 0.0.0.0
UG 1500 0 ppp0
My eth0 card IP is 192.168.0.30
and the other two computer is 192.168.0.1 and 192.168.0.2
I can using all the Internet Service in my Linux Machine, but
when I using ping in the other two computers. They just
ping the IP address for the domain name. e.g.
ping ozemail.com.au (203.2.194.3)
Request Timed Out
What should I do next, to enable the NT computer to use TCP/IP Service?
How can I mapping the services and
What is the setting option of the NT TCP/IP protocal?
such as DNS is it equal to my IP address, and Gateway is the one in
routing table?
Thank You very much.

Subject: About Window manager, Licq and gftp!!
Date: Fri, 25 Jun 1999 01:33:11 +0800
I am a new linux user and I am using RH6.0:
There are three simple questions I want to raise:
1. I have my licq installed, but under my NT partition, I can play ICQ
via a SOCKS 5 proxy server with
the ICQ version for win98/winnt. I wonder how should I config the licq
so that I can
play it via a SOCKS 5 proxy server.
2. I have a problem with the use of my gftp. I can't get connected to
any sites and the
reply is: "No route to hosts". Well, I can ftp, get and put files using
simple
command prompt ftp. So, why can't I ftp with gftp? And what's the
meaning of no route
to hosts?
3. The third one: How to switch between different Window manager? I have
the xfce RPM format installed,
but I don't know how to start it once I login. Currently, I can switch
to use AfterStep and fvwm.
Well, how could I switch to use xfce when I am using AfterStep??
Looking for your reply! Pls help!

You could just write the mail program into their script, and then when they
exit mail, tell the computer to log them out. It is very common, used largely
with Lynx.

Your passwords are NOT kept in this file. Instead there is another file in

Subject: Windows95 box -> Linux Box (Static IP) -> Intranet -> Internet?
Date: Thu, 24 Jun 1999 11:35:43 -0400
Folks,
I have 1 static IP line into my office. I have a linux box and a win95
box and a hub. I want to have the Linux Box connected to the static IP on
eth0, and connected to the hub on eth1. And I want to have the Win95 box
connected to the hub.
What I need is for the Win95 box to be able to go through the Linux box
and see the intranet, and also the internet (via proxies off of other
servers on the intranet).
But how do I get the win95 box to see the outside world? It can see the
linux box, but that's it. DO I need to do some kind of IP forwarding on the
linux box so packets think they are going to the linux box but actually go
to the windows box? I'm a little lost.
Where's a good place to start to find info on this?
Thanks much,

If you want email access, you need to map a certain email server through the
mathcing port. I think Wingate might have its own email distribution
service, but if not, try WinProxy. It has everything (DNS,DHCP, Mail, News,
Firewall, everything). Or you can try spoonproxy, which is what I use. It
is very simple (WinProxy is extremely complex) and includes HTTP, FTP, Real,
Socks, HTTPS, and Telnet proxy ports. I think the Socks port expires after
30days, but you can still map services through (news servers, mail servers,
etc.).
