Help with Fazzt downloads needed
Hi
I cannot get any transfers using Fazzt client on a Win98 PC. My win98 has address
192.168.16.203 (eleanor) and has as its def gw a Linux box where the dvb card is
installed and running. I have no problems downloading web pages through eon proxies.
Dvb card is tuned to transponder 114.
The hosts I have on the internal net are
eleanor (win98) 192.168.16.203
lothlorien (linux internet gw with dvb card installed) 192.168.16.3
jetdirect ( a jetdirect :D) 192.168.16.10
I use dvbd to tune the card, after this, i start mrouted with this config file:
------------ start of /etc/mrouted.conf config file -----------------------
cache_lifetime 3600
pruning off
phyint dvb0 altnet 128.0.0.0/1 altnet 125.0.0.0/1
phyint eth0
dvbauto on
------------ end of config file -------------------------
and got that output:
-------------- start of mrouted output ----------------------------------------

-------------- end of command output -----------------------------------------------------
As far as i know, i don't see any message/config line that tells mrouted to exchange
membership information with eon's mcast routers, i suppose this is one of my faults. On
the other hand, how do i tell eon's mcast systems where am i? I mean when i select a file
download with my browser, how do eon's mcast systems know than i am listening on
242.242.242.242 group? Should i join another special mcast group to get the files?
Please, would any of you be so kind as to unstuck me?
Thanks in advance for all your help, if you need further data don't doubt contacting me.
