Is there any problem if I upgrade kernel 2.0.35 to 2.2.1. on a Redhat 5.1.
machine ?
Should I also upgrade some packages ?
I looked at the Redhad support page for Redhat 5.2 upgrade and it doesn't
say anything about 5.1 upgrading.
Thank You,

cisco 1003 with IOS 12 with a recent maintaince release, ip plus feature set
required for ip nat
or cisco 1603 with a recent maintaince release of 11.3, ip plus feature set
required for ip nat
the performance of both depens entirely of what servives yuo have configured,
but with a basic secure config, they will both easily saturate a 64K pipe as
well as a 128K ISDN bundeled MPPP (RFC1717) pipe.
also both will handle ip firewalling, wil very little overheads.

Subject: can't ping Linux --> win98
Date: Sat, 13 Mar 1999 23:56:42 +0100
I've tried to set up a network the last couple of days. But now I'm at a
standstill.
I do not know where to start.
The network consists of 4 computers. One linux box acting as a gateway with
IP masq. The other comps are Win98. All the win98 comps are configured
correctly and can share files printers etc, but I can't even ping to / from
the linux box.
Linux box = Pentium 60, 3com 3c900, Slackware 3.6, kernel 2.2.3,
I can connect to the internet with the linux box with a PPP script. And from
there I can do telnet, ftp whatever. So there is nothing wrong with the
TCP/IP function on any computer.
The cable (BNC) is working, I used it to connect one of the win98 comps, no
problem.
The card is detected at boot. ifconfig looks good. route aswell. netstat -nr
shows up as expected.
I've tried to just configure one win98 comp so it would be able to ping the
linux box. Removing all non essential stuff. TCP/IP, client for Microsoft
Networks and my ethernet adapter was all I spared. I configured the TCP/IP
like this:
IP address: 192.168.1.3
Netmask: 255.255.255.0 (same configuration as the linux box)
Gateway: 192.168.1.4
DNS:
host: mycomp
domain: zeus.mynet.com
DNSservers: IP addresses of my ISP's nameservres
Bindings: Client for microsoft networks - check
As for Identification on the win98 box I haven't changed anything. I use the
same comp name as I wrote in the /etc/host file on the linux box.
It could be my 3com card that is simply not working. I'll try that very
soon. But apart from that I don't know what it could be.. I know I haven't
covered every detail of my network configuration /setup. I'll be more than
happy to give you the details.
Anything! Please help me out here.. You are my only hope..
/P. Leia =)

Subject: Using the kernel firewall code like tcp wrappers to harden a single host.
Date: Sat, 13 Mar 1999 23:01:18 GMT
I have used the in-built firewall facilities in the Linux kernel to
create firewalls before, but I was not aware that you can use the same
facility on a machine with just on network card to defend the services
that run on that box.
However, while playing with ipfwadm on a single net-card box, I
noticed that I could limit access to services by setting a default
policy of deny for inward and outbound packets and then setting up
rules to accept legitimate traffic. In this mode the firewalling code
is acting like tcp wrappers.
This method of protecting services can be used to harden a box that is
exposed on a DMZ or the public side of the Internet (e.g. a Linux web
server).
Anyway, this might be old hat rather than news, but I have not heard
of this facility after reading a lot of stuff about Linux firewalls
and so I thought that it might be useful to other people.

John Auld

One way or another, you have to be logged onto the Linux box to shut it
down. If you have an xterm in OmniX, you can do it from there. Just
remember to end the command line with ' &' so it continues to run when you
log off. And if you enable shutdown for a normal user, include the path:
/sbin/shutdown -h +2 &
should shutdown in 2 minutes, even if you log off.

So, what's wrong with using LILO? I boot to 4 different systems on 3
different IDE drives without having to change any jumpers. All the OS's
do not go on the MBR, just pointers to where they are.
LILO can boot to any drive that shows up in CMOS setup (in which case you
can ignore the warnings). Just make sure that CD or other removable
drives are last (especially if they do not show in CMOS).
Of course I have no use for NT or Netware, so I don't have a clue if they
boot any different from Win95.

If you cannot even telnet to yourself, don't expect to be able to do it
from anywhere else. The first time I installed RH5.0 the loopback was
missing, for some reason. When I reinstalled, it was there. It is
necessary to do anything network related.
What do 'ifconfig' and 'route -n' show?
Do you have names for your IP's in /etc/hosts and \windows\hosts?

that I am appempting to apply 2.2.1 ( for video for linux functions) I
cannot get Masq to work correctly. Iam using the 192.168.1.X subnet with the
following ipchains:
ipchains -P forward DENY

I have dhclient up and running the router gets the lease from the DHCP
server fine the route looks good:

I can telnet to and from all the machine behind the router but cannot get
out of the local net except from the router. Everthing seems to checkout
fine per the ipchains howto.

Subject: PPP dialing to ISP is not working with RedHat 5.2 and Gnome 1.0
Date: Sat, 13 Mar 1999 16:48:26 -0500
I can't seem to get PPP working when trying to connect to my ISP when
using the PPP-Dialer that is built into Gnome 1.0. With the PPP-Dialer
my modem dials out but never establishes a connection. If I configure
things so that I'm not using Gnome and instead use the standard RedHat
install mode of XWindows and FVWM, and fire up PPP using the
Gnome-Linuxconf program, that comes with RedHat 5.2, I can connect just
fine.
Is there a bug in Gnome's PPP-dialer program? I find it strange that
when using the Gnome-Linusconf program I see a PPP configuration named
ppp0 that works yet when I go into Gnome and use the new PPP-Dialer the
ppp0 configuration doesn't exist and I can't connect with a newly define
configuration.
How do I fix this or is it even possible?

Subject: Diald and a few problems....
Date: Sat, 13 Mar 1999 18:24:47 -0600
I have gotten diald to work (mostly), but have a few problems:
1. diald apparently keeps creating slip connections. In just a few hours
of testing, I've got sl0 - sl20. They don't die.
2. diald hangs up fairly quickly (about 60 seconds). I have tried
extending the timeout in pppd, but diald apparently is killing the
connection. Is there some overall timeout for diald?
3. diald keeps coming up with "accepted rule 22 proto 17 len 64" that
appear to be going out to nameservers. These are not only the default ones
I have set up for my ISP, but also the ones defined in /var/named/named.ca.
I am using RH 5.2, with the <diald-0.16.5a-1.i386.rpm>. I have a caching
nameserver defined (which seems to work per DNS howto instructions), to help
prevent the link from coming up all the time.
Any ideas?

I have Samba (2.0.3) set up, and am enduring long login/attach times when
trying to view the shares on the samba server. In other words, on Win9x,
going into Network Neighborhood, and double clicking on the samba server...
It seems to take 1.5 - 3 minutes.
I have samba set up as a WinS server - setting up my Win9x box to point to
the samba host for Wins services, pings are very quick (no local
\windows\hosts). This is with no DNS set on Win9x
I also have a caching nameserver on the same linux box. Using DNS on Win9x,
but no Wins, pings are also very quick.
I'm convinced the name resolution is happening quickly, but the attach/login
is very long. Once up, though, access to the shares and displaying their
contents is very quick. Copying files to the samba server is also very
quick.
Any ideas?

The rules are ok, but they are added to the forward chain. What you can
view with 'ipfwadm -M -l' is the list off currently "established"

No ... actually quite some time ago there was an announcement about just
that, a programme to shut down a Linux box remotely. Should not be a big
deal via some daemon or RPC (though RPC is not that secure ... ) that does
just that.

Well, I don't think you necessarily need System Commander to boot multiple
operating systems. On my computer at work I have win95, NT4.0 and
Redhat5.0 and I was able to get them all to boot using the NT boot loader.
I just pick which operating system I want and away I go. I will say it
was a sleight headache to set up though because the primary partition on
my hardware is formatted NTFS, but its definitely workable.

jiffies is a global variable which is counted up continously. It's
increased by one each 1/HZ seconds (HZ is a symbolic constant). You may
have noticed that there are some funtions that can be used to compare it
with a stored value, e.g. time_before, these are used because jiffies
may
wrap arround.

As you are posting this question to a Linux group too I suppose you want
a sulution running under Linux.
You can use the C-functions provided. There is a function gethostbyaddr.
Type in "man 3 gethostbyaddr" for more information about. You might want
to read "Unix Network Programming - Volume 1" by R.W.Stevens (ISBN
0-13-490012-X). This is all for C though. There might be C++ libraries
arround that offer this functions wrapped into a object or you might
write one yourself.
