Is there a page where I can get info on how to forward ports through my
firewall? I scanned the howto's and couldnt find anything really meaningful.
What I am really looking for is a way to get my realplayer working. I have the
ipmasq_raudio module running, but I think my problem is with the firewall
permissions.
Thanks in advance.

Hi,
the NFS daemon running on redhat 5.2/kernel 2.0.36 seems to die
after a certain time of usage. Indeed, the deamon is still running
but accesses to exported directories result in RPC timeouts. If NFS
is restarted then everything is ok.
The Linux machine is automounted by using the params rw,soft,intr,nosuid.
Curious is that there are no problems between Suns using the same
network and the same mounting parameters.
Thx for every hint.

- Plug cisco console cable into a serial port on the linux
- Install & start Minicom
- Go to the menu (CTRL-A Z)
- Set "Configure Minicom --> Serial Port Setup": Serial device:
/dev/cua1 (or whatever port you use), hardw.flow.cont.: No,
softw.flow.cont.:No
- Set "Comm.Parameters": speed 9600, parity none, stopbits 1 (9600
8N1)
- Set "Terminal Settings": emulation VT102
- Leave menu and press <enter>
And now a console login should appear. This should also work for
Portmasters and other hardware with a console.

Most CDs you buy don't contain the latest kernel. Go to ftp.kernel.org and
get the latest stable kernel. There's a kernel HOWTO at

Content-Type: text/plain; charset=US-ASCII
Hi all,
I am currently running a Linux system with kernel 2.2.3, glibc 2.1 and
net-tools-1.51 (the following also happened with net-tools-1.50)
1. While setting up my loopback connection to 127.0.0.1 using the
following commands:
ifconfig lo localhost
route add -host localhost
I get the error message:
SIOCADDRT: No such device
Changing the latter command to:
route add -host localhost lo
works fine.
Although in the first case no route will be set up, I can `ping
localhost' anyway. Is there an implicit route?
2. Setting up my ethernet card using the command
ifconfig eth0 192.168.111.2 netmask 255.255.255.0 up
results in the error message (caused by set_netmask() in ifconfig.c)
SIOCSIFNETMASK: [...]
The interface works however.
When I don't specify a netmask the function will not be called and
hence I don't get that error message.
The described behaviour is different from that of my 2.0.36 kernel
system.
Any opinions?
Thanks,
Marcus

Subject: can't telnet to my machine
Date: Wed, 24 Mar 1999 18:20:42 GMT
I have a RH 5.0 box. I am unable to telnet or ftp to that machine from any
other machine on the network, although I can ping it, use apache, etc. It is
able to access other machines as well. I am able to telnet to 127.0.0.1 on
that machine, and to its ip address (192.168.0.1). My /etc/hosts.allow and
hosts.deny files are empty, so I don't think that's the problem.
Any suggestions would be greatly appreciated.
Thanks,
Jim Hanson

A good software especially for DAT and other SCSI tapes is arkeia. Its a
client server based system that you can get for free (for non commercial

Look at http://www.arkeia.com/

I'm not too familiar with AOLnet, but if that pop3 server can be hit
successfully with Windows Netscape, it can be done with Linux Netscape too
in the same manner.

Subject: multi-link PPP?
Date: Wed, 24 Mar 1999 10:56:11 -0500
Is there support for Multi-link PPP in the built in Linux PPP driver or
via add on software?
Here's what I want to do. I want to put a Linux box on our corporate
network with four modems in it. Then I want to enable two sys-admins to
dial-up to two modems each and aggregate the bandwidth into one 67.2Kbps
link (i.e. 33.6 x2) Also I want the dial-up connection to be assigned
one IP that is one of the fixed IP's assigned to our Ethernet LAN so
that the dial-up's appear to be on the LAN (which is on the Internet).
This way the dial-up boxes can also be reached from the Internet as they
will have legitimate Internet IP's. The dial-up boxes do not have to be
Windows boxes, in fact I prefer they were Linux boxes.
Anyone?
Thanks in advance,
Christopher A. Gaul

Hello,
The first one is the sendmail binary and some related stuff. The
second is the /etc/sendmail.cf (which you need). Red Hat packaged the cf
separately to allow easy modifications to the default config. This saves
you the trouble of having to download a complete sendmail package when RH
updates the cf. I am not sure about the config rpm. The only other
sendmail rpm I could find was the sendmail-doc. If they are from RH, get
them all.

The address is in the DHCP-Mini-HOWTO, it�s on an ftp server somewhere

That does it!
arp -i eth0 -Ds my_plip_hostname eth0 pub
(I also had to update my firewall rules to allow forwarding.)
And there's a good reason why bridging doesn't work with PLIP.
Bridging is an ethernet-level activity. PLIP, at least in name, is an
IP level protocol, not a virtual ethernet. Hence, PLIP can't be
bridged.
ProxyARP is the process of getting an ethernet interface to tell the
rest of the world that packets for a given IP address belong to its
ethernet address. This is similar to network aliasing, except that
when it comes to routing from the local machine, it doesn't believe
that it holds that IP number.

Now, this answer is from a TCP/IP and networking perspective, not
necessarily a Linux one. What you need is to set up a bridge, not a router.
You can still run a firewall inside, but the routing will be done on Layer 2
instead of Layer 3. There is a bridging HowTo, but I do not remember the
name. Once you have your bridge set up, one NIC will be on a hub with your
Internet router and all "unprotected" systems, and the other NIC will be on
a hub with all of your "protected" systems. The speed of this
firewall-switch will be directly dependent on bus speed, so I recommend a
P-II with a 100mhz bus. As usual, no other services should be run on your
firewall, for both security and performance reasons.
