Hi,
im using an embedded arm9 system.
I boot the system through a initrd. The initrd contains the kernel
(2.4.21) and the root-filesystem.
After the boot a script executes the following to bring up the network:
hostname embedded-system
ifconfig eth0 add 192.168.0.151 netmask 255.255.255.0 up
route add -net default gw 192.168.0.1
I have problems with the network. If I use e.g. "ftp server-ip" or
"telnet server-ip" I always get:
"connect: Connection timed out" after approx one or two minutes.
The server I try to connect to is running no firewall, I can establish
a connection to the server from another client successfully.
I can ping from the embedded system to the server and vice versa.
ifconfig on the embedded system show no errors or drops. But Im using
a strange MAC (11:11:22:22:33:33) although this shouldn't matter since
I connect the embedded
system and the server directly through a cross-over cable.
However : "nmap -A ip-of-embedded-system" executed on the server:
"Note: Host seems down. If it is really up, but blocking pur ping
probes, try -P0
Nmap finished: 1 IP address (0 hosts up)"
Strange, since ping works.
output of ifconfig:
root@embedded-system:/>
ifconfig
