Satellite connection and RH 8, 9 or Fedora


Hi All

I'm been fighting a networking problem for quite some time and I am running out of ideas. Any one have experience in configuring the network to work with a high speed high latency satellite connection.

The bigest proglem I have is getting the up2date app to download all the rpm files with out the network connection dying. I've been playing around with a config script and it help but the network connection is still very flaky.
My linux box is connected to a windows based router, thank you Direcway for not supporting linux


here is the script and any suggestions welcome tia

echo configuring network, please wait ...
sleep 1
service network stop

# sets rwin size (receive)
echo 262144 >> /proc/sys/net/core/rmem_default
echo 262144 >> /proc/sys/net/core/rmem_max
# default wmem or transmit 64K
# 1x 65536
# 2x 131072
# 4x 262144
# 5x 524288
#calculated 624000
# sets transmit win size
echo 131072 >> /proc/sys/net/core/wmem_default
echo 262144 >> /proc/sys/net/core/wmem_max

# logicals 0 = yes, 1 = no
# window scaling yes
echo 0 >> /proc/sys/net/ipv4/tcp_window_scaling

# timestamps no
echo 1 >> /proc/sys/net/ipv4/tcp_timestamps

# selective ack's yes
echo 0 >> /proc/sys/net/ipv4/tcp_sack

# path mtu discovery
echo 1 >> /proc/sys/net/ipv4/ip_no_pmtu_disc

# missing black hole detect
# max dup ack

# ttl
echo 64 >> /proc/sys/net/ipv4/ip_default_ttl

# sets mtu current max is 1462, but more stable at 500 to 1000
ifconfig eth0 mtu 500

touch /var/lock/subsys/local
service network start
echo network restarted, exiting...
sleep 10

IF you mean using the proxy 192.168.0.1 port 85 then that would be a yes.

I beg to differ with you on Direcway offering Linux support, last time I spoke with them they did not even know what a linux was. can you say dumb as a doorknob? Direcway did come out with a model 6000 modem stack but I don't have that system, nor would I want it. SO back to the original issue of getting a reliable connection thru a windows based router using direcway as the gateway.

Ideas ?
