if you use redhat, try using the 'rpmfind' tool available at
http://rufus.w3.org
then you can upgrade by issuing command 'rpmfind --upgrade ghostscript'
and 'rpmfind --upgrade ghostscript-fonts'
It will tell you whether or not you even need to upgrade.

NFS is just this slow because it relies upon RPC calls they are pretty high up
in the OSI model so cost alot of time.
This is also the reason why Novell and IBM/M$ created there own fileserver
implementation.
If you would like better performance install samba and smbmount a share.
This is about 8 times faster.

You should look into creating static arp tables. I'm not sure if this
is possible under 2.0 but I think there may be some software that makes
this possible. Maybe a patch to the kernel?

Subject: AOL with IP masq
Date: Tue, 19 Jan 1999 17:26:14 -0500
I will soon be setting up a network at work, and everyone will be
sharing an internet connection, most likely either ISDN or cable with a
Linux box masquerading for a gateway. Some people there use (ughh...)
AOL in addition to your standard netscape and M$ Outlook and whatnot.
Are there any special masquerading rules I must set to allow AOL to
connect through masquerade? I ask this because at home I have 2
computers sharing a connection through a windoze PC running wingate, and
AOL didn't work until I got a licensed version. The unlicensed version
allows the computer it's running on, along with one other computer to
share a connection. I'm assuming that AOL opens a socket on the client
computer, making wingate think there's 3 computers sharing and it won't
let it through. If so, I thought maybe I'd need some weird settings for
masquerading too. If anyone has set up AOL behind an IP masquerade,
please let me know if you had to do anything special.
thank you

Check what you have in /etc/ppp/options. Make sure you have host
and client IP addresses and a netmask specified.

Subject: IP_Forwarding w/RH5.2
Date: Wed, 20 Jan 1999 03:21:49 GMT
Thanks to all who have responded to my request for help with IP Forwarding.
Unfortunately, I am still unable to get my box to forward packets.
To date, I have performed the following:
1. Recompiled the kernel for ip-forwarding and firewalling.
2. There is a "1" in the /proc/sys/net/ipv4/ip-forward file.
3. forward_ipv4=yes in the /etc/sysconfig/network file.
4. At least one script in the etc/rc.d/init.d directory looks for these
files. I inserted echo statements to myself to insure that the files
were being read during start-up.
5. I have gateways set-up for both ethernet interfaces. The local
interface (192.168.48.30) uses the network-side interface as the
gateway and the network-side interface uses the upstream router on
the network as the gateway.
6. From a workstation on the local 192.168.48.0 network, I can ping both
interfaces on the Linux box, but not beyond. The traceroute shows that
any host on the same segment as the network-side interface or beyond
cannot be reached. Hence, I believe IP_Forwarding is not working.
7. I have not yet placed any ipfwadm commands in start-up scripts,
therefore I assume all packets should get forwarded at this point in time.
Any more suggestions would be greatly appreciated.
I'm feeling quite perplexed. Thanks.

Subject: Weird 3COM Card Problem - Help Please
Date: Tue, 19 Jan 1999 16:44:32 -0500
Reply-To: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]>
My problem with my 3COM problem continues, any help would be GREATLY
APPRECIATTED
Problem: System hangs during "boot" with new PCMCIA multi-function card.
=======
Background:
==========
-IBM ThinkPad 600
-Dual Booting Windows 5.2 and Macmillan RedHat 5.2 - new clean install
-Trying for almost a week to get a new 3com 3CXEM556B to work.
-Card installed great in WINDOWS, works perfectly, WINDOWS gave it IRQ 9,COM
3.
Things tried so far:
==============
-Re-Install of RedHat
- edited "/etc/pcmcia/config.opts" to add "exclude irq 3, irq 5, irq 7, irq
12, irq 15"
- This was to force it to use IRQ 9 which was the only left and whic
it was not picking up
otherwise.
- This seemed to help, system still hung, but if I popped the card out
so it would continue to "boot"
I could "cat /proc/interrupts" after "boot" was complete and it
looked like card was getting the
IRQ 9.
-Booted with card out then inserted card.
- No Joy, system did not detect card insert
-Booted with card out, put card it, entered "cardctl insert"
-This locked the system up solid. But I could "pop" the card out and
it would respond. Put back in, it would lock up.

Which is essentially what "/etc/init.d/netbase stop" does to inetd and
portmap. "/etc/init.d/netbase start" starts inetd and portmap and also
sets up some anti-spoofing stuff.

What are you doing trying to route to a 192 network anyway? Just put together
your ipfwadm commands, insmod the various masq modules, and use NAT! What are

I do not have DSL -- yet -- but a possible problem might be: Is Linux running
on the same machine as 95? DHCP can be configured to only issue an address to a
known MAC address. The symptom you describe (no DHCPOFFER) is exactly what I
would expect if your Linux box was an "unknown host" to the DHCP server. This
does not apply if 95 and Linux are running on the same machine and using the
same NCI card.
