Hello forum,
Yesterday my small web server made some troubles which were for me absolutely unclear.
Here a an abstract from /var/log/messages:
# dmesg
Before this there were no messages or other hints and while this messages were written to syslog the other WLAN clients had no problems.
After restarting the network interfaces (service netif restart) everthing is running without problems.
Network hardware: EDimax EW-7811Un:
Operating system:
Network configuration:
Hardware: Fujitsu S900, AMD G-T40N Processor (997.90-MHz K8-class CPU), 2GiB RAM, 160GB HDD Seagate Barracuda
Now I'm trying to understand this behavior. I hope someone can explain it to me.
Thanking you in advance
JueDan
PS: the WLAN connection is a temporary solution and it will be replaced by LAN cable when the small webserver has its final location
