Re: [K12OSN] Client can't get IP



Joe,

I don't know what the problem is. One terminal that failed to get IP is now succeded to catch the IP reserved to it in dhcpd.conf. But the boot process is stop at "loading 192.168.0.254:/lts/vmlinuz
.ltsp............. .". I didn't do anything.
I really need any suggestion.
Here I attach the result captured from wireshark.
