Hi,everyone!
My system: redhat 9.0 server edition rtai3.0r4 rtnet0.7.1 NIC: Realtek 8139 On master, do "rtping <local IP>" successfully, but do "rtping <remote IP>" unsuccessfully. System hinted "ioctl: No buffer space available"
On client, do "rtping <local IP>" unsuccessfully, do "rtping <remote IP>" unsuccessfully too.
Do "ping <local or remote IP>" unsuccessfully too.
The example "round_trip_time" was also run unsuccessfully.
Did anybody run across the problem? What's wrong with my system?
Thanks in advance!
The following is the configure file "rtnet.conf"s and the execution results of master and client respectively.
On master(192.168.1.56):
/etc/rtnet.conf [ #!/bin/sh # RTnet installation path RTNET_PATH="/usr/local/rtnet"
# RT-NIC driver RT_DRIVER="8139too-rt" RT_DRIVER_OPTIONS="cards=1"
# IP address and netmask of this station IPADDR="192.168.1.56" NETMASK=""
# Start realtime loopback device ("yes" or "no")
RT_LOOPBACK="yes"# Start capturing interface ("yes" or "no")
RTCAP="no"# Common RTcfg stage 2 config data (master mode only) STAGE_2_SRC=""
# Stage 2 config data destination file (client mode only) STAGE_2_DST=""
# Command to be executed after stage 2 phase (client mode only) STAGE_2_CMDS=""
# TDMA mode of the station ("master" or "client")
TDMA_MODE="master"# List of TDMA clients (master mode only) TDMA_CLIENTS="192.168.1.88"
# Cycle time in microsecond (master mode only) TDMA_CYCLE="5000"
# Offset in microsecond between TDMA slots (master mode only) TDMA_OFFSET="200" ]
After I shut down standard linux netword, loaded required rtai modules and rtai_rtdm.o, and I did:
