[lwip-users] problems with the RTL-LWip

[liu kun]

hi,list:
  hi,all.I have installed the RTL-lwip0.4 in two machines(linux 
2.4.20+RTLinux-3.2-pre2+realtak8139),and there is no problem during the 
installation this time.Since the document tell me that before use the 
driver for RTL-lwip,the ethernet card driver for linux must be down,so I 
didn't install the 8139 driver for linux.But now I can't use the examples 
to check if RTL-lwip goes well,such as the tcp_echo and udp_tcho.

The steps will be show as follows:
address@hidden RTL-lwIP-0.4]#rtlinux start
address@hidden RTL-lwIP-0.4]#./instools
address@hidden RTL-lwIP-0.4]# insmod rtl_rtl8139_drv.o

RT-Linux driver for the Ethernet Card rtl8139 being loaded                  
    
Registered device /dev/rtl major number 205 

address@hidden RTL-lwIP-0.4]# insmod rtl_lwip_stack.o
RTLinux TCP/IP stack inserted. linux thread id: 0xc4831ec4
System initialized.

rt_rtl8139 interface added to netif list
rt_rtl8139 set as default

   Anyone can tell me whether the RTL-lwip dirver have installed 
successfully it seems there is no wrong with the installation.but I can't 
find the device "/dev/rtl"(why ?).And next I used the example 
udp_echo/tcp_echo in two RTLinux machines-insmod 
udpserver.o/udpclient.o,there is no result shows the communication between 
them goes well. I think I have changed all the neccessary configuration,and 
the machines IP are 192.168.0.1 and 192.168.0.2. Can any one please help me 
with the problem,and how I can check my RTL-lwip's working status ?
thanks in advance
with best regards
