Don't know if this helps, but I had a similar problem mounting linux
exports on an SGI O2 (IRIX) about a year back. The problem turned out be
a misreported version mismatch, so you might want to try including
nfsversion or nfsver or vers or whatever the version option is called
nowadays = 2in your fstab.

The "stock" redhat supplied kernel already has ip_masq_portfw.o. I did not
have to recompile the kernel to get this feature working. You should look
for this module in directory /lib/modules/<kernel-rev>/ipv4. If you have
recompiled the kernel, then make sure you enable the following options...
(check /usr/src/linux/.config)
#
# Protocol-specific masquerading support will be built as modules.
#
CONFIG_IP_MASQUERADE_MOD=y
CONFIG_IP_MASQUERADE_IPAUTOFW=m
CONFIG_IP_MASQUERADE_IPPORTFW=m
CONFIG_IP_MASQUERADE_MFW=m
Then when you compile/install the modules, you should then see
ip_masq_portfw.o This module "must" be loaded prior to issueing any
ipmasqadm command. If your still having problems getting ipmasqadm working
and are anxious to get port forwarding working, consider downloading
"rinetd". It is alot easier to configure than ipmasqadm. The only difference
is it runs as a separate "deamon" on the process stack. Very small memory
utilization.
As for your other question regarding "restricting" port forwarding to a
source address or network address (like from a specific internet address),
you should take a look at the module documentation on ip_masq_mfw. Since I
travel and use ISP's all over the country, I elected NOT to use this method
of prot forwarding.
An example from the man pages on ipmasqadm using mfw instead of portfw...
note using the "mark" tag using ipchains.
Redirect all traffic from external clientA to internal
hostB, also show forward masq rule to allow this for hostB
only.
ipchains -I forward -d clientA/32 -s hostB/32
ipchains -I input -s clientA/32 -m 3
ipmasqadm mfw -I -m 3 -r hostB

Hmmmmm. Considering that ifconfig must be able to do this (since it
shows IP addresses on a per-interface basis), have you considered
getting the ifconfig source code (most likely in a 'netkit' package?)
and examining that?
Not sure how portable it is, 'tho, not having looked m'self.

It fooled me, I though the "default" came from the default entry in my

Actually I do not understand why your system is sending the EchoReq.? Is
there some option to pppd which requests this?
Do you have the lcp-echo-interval option defined in /etc/ppp/options?
You do not say how you connect. If you have it, why do you have it?
This is for keeping track as to whether or not the other end is still
alive, so you can shut down your end if they go away. It does not seem
to be very useful on a telephone connection since the phone line will
usually drop when the far side drops the connection.
I saw this when I connected to freeserve in the UK as they kept sending
EchoReq to me, polluting my log file. I could never figure out why, but
I guess they had their reasons (or like you simply had it for some
unknown reason).

Hi, all
Situation is as follows:
W95 <-> eth1/linux box/eth0 <-> smb network <-> gateway to internet
eth1 address: 10.0.100.1
eth0 address: 10.0.0.203
gateway is 10.0.0.1.
Problem: W95 computer cannot access smb network. Internet (on W95
computer) works o.k., ping/tracert/etc goes through, but smb packeds
does not reach W95 box. I've made my linux box as WINS server, and W95
is now able to see smb names (but not shares). When I try to access smb
share from W95 computer, error such as '\\computer_xxx is not accessible
<..>" occurs. Maybe my ipchains are incorrect? They look like so:
echo "1" >/proc/sys/net/ipv4/ip_forward
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -j MASQ -p TCP -s 10.0.100.0/8 -d 0.0.0.0/0 -i
eth0
/sbin/ipchains -A forward -j MASQ -p UDP -s 10.0.100.0/8 -d 0.0.0.0/0 -i

I'm looking for a basic subnet routing setup for all items on the same

linux box to route between the two local subnets. I have configured
eth0 as 172.30.91.62 and eth0:0 as 172.27.222.222. I have added routes
to both networks. When I attempt to telnet to 172.27.14.1 from
172.30.91.63, I get the telnet login prompt for my linux box -
172.30.91.62 (no forwarding) what am I doing wrong? Do I need to setup
rules in ipchains? I am using RH 6.0 with the default Kernel config. I
haven't done any kernel updates. Any help would be appreciated. Thanks!

I had a similar problem with a 3com 3c509 Ethernet card and an adaptec

Hi.
we're using redir and ipchains for our firewalls.
we're starting to have a problem where the redir
agents will expire after an unknown time.
we've put a while true ; do redir <blah> done so
that it respawns after expiration, but we end up
with: server: bind: Address already in use --
this sucks.
when we do a netstat, we end up with what looks
like the socket still being open, even though
redir is not in the process list.
We're using redir because we can't figure out how
else, when the traffic is redirected, it's source
appears to be the firewall which said traffic
passed through -- this is important because we
have two firewalls.
anyway, any help is wonderfull.

I don't know about USWest, but I do this with BellSouth. Do you know the
protocol they use to assign IPs? Good chance its DHCP. Is there a static
IP instead? Which distro?
DHCP is pretty easy to setup. On RH6, all I had to do was start
'netcfg', select interface 'eth0', select protocol 'dhcp', and 'start on
boot', then hit 'activate' button. DHCP does all the negotiation based
on the MAC address of the NIC which they already have. If you use RH6,
get the 'pump' update first.
