Hi! I've installed the svn snapshot from a few nights ago and i'm on the "Waiting for all slaves..." phase.
I've tried to understand how to configure rtnet (rtnet.conf) but i don't understand some things, like "backup-offset" or "slot" on tdma.conf. What I intend to do is to create a network with 3 computers, each one with 3 realtek ethernet cards. I have vnic0 and rteth0. Is there some configuration files to setup (per example) the simple case of having two computers, connected by one ethernet card each? Thanks for any help! 2006/3/3, Jan Kiszka <[EMAIL PROTECTED]>: > Teresa Noviello wrote: > > On 3/3/06, Jan Kiszka <[EMAIL PROTECTED]> wrote: > >> Teresa Noviello wrote: > >>> I have installed rtnet (latest version on SVN server, with the command > >> "svn > >>> checkout http://svn.berlios.de/svnroot/repos/rtnet/trunk";) on slackware > >> 9.0, > >>> kernel 2.6.10, rtai-3.3. > >>> I' ve done make && make install and i've done mknod of /dev/rtnet as the > >>> README file says. > >>> On this system, i have got two network adapters, Intel 10/100. > >>> Then i've done > >>> > >>> 'ifconfig eth0 down' > >>> 'ifconfig eth1 down' > >>> 'rmmod eepro100' (network module)' > >>> > >>> then in /usr/realtime/modules > >>> > >>> 'insmod ./rtai_hal.ko' > >>> 'insmod ./rtai_ksched.ko' > >>> 'insmod ./rtai_sem.ko' > >>> 'insmod ./rtai_rtdm.ko' > >>> > >>> then i've modified my /usr/local/rtnet/etc/rtnet.conf with: > >>> > >>> RT_LOOPBACK="yes" > >>> RTCAP="no" > >>> STAGE_2_RG="" > >>> STAGE_2_DST="" > >>> STAGE_2_CMDS="" > >>> RT_DRIVER="rt_eepro100" > >>> IPADDR="10.0.0.1" > >>> NETMASK="255.255.255.0" > >>> TDMA_MODE="master" > >>> TDMA_SLAVES="10.0.0.2" > >>> TDMA_CYCLE="5000" > >>> TDMA_OFFSET="200" > >>> > >>> when i do in /usr/local/rtnet/sbin > >>> > >>> ./rtnet start, i have > >>> > >>> "Waiting for all slaves..." > >>> > >>> and in > >>> > >>> dmesg: > >>> RTnet: unknown layer-3 protocol > >> Hmm, not an isolated network for RTnet?
