errors in netconsole script...

I try to use http://jeff.doozan.com/debian/uboot/netconsole described in http://jeff.doozan.com/debian/uboot/ but i get some errors:

$ ./netconsole 192.168.1.100
NOTE: the interrupt signal (normally ^C) has been remapped to ^T
ncb: not found
usage: nc [-46DdhklnrStUuvzC] [-i interval] [-P proxy_username] [-p source_port]
	  [-s source_ip_address] [-T ToS] [-w timeout] [-X proxy_protocol]
	  [-x proxy_address[:port]] [hostname] [port[s]]

I add a "set -x" and see this:

$ ./netconsole 192.168.1.100
+ [ -n 192.168.1.100 ]
+ break
+ ip=192.168.1.100
+ port=6666
+ [ -z 192.168.1.100 ]
+ [ -n  ]
+ type netcat
+ break
+ trap stty icanon echo intr ^C 0 2 3 5 10 13 15
+ echo NOTE: the interrupt signal (normally ^C) has been remapped to ^T

+ type ncb

+ [ -x ./ncb ]
+ netcat -u -l -p 6666

	  [-x proxy_address[:port]] [hostname] [port[s]]
+ kill 1471
+ stty icanon echo intr ^C

I find the right syntax from http://buffalo.nas-central.org/wiki/NetCat-A_UBoot-Friendly_Network_Utility :

nc -u -p 6666 -v 192.168.1.100 6666

This works.

Hi there,

I've been messing around with nc and netcat and had various levels of succes. After googling and searching I found the command socat, which has a lot more options and features than nc and it seems to work more reliable as a netconsole terminal, because there is only one command needed.

# socat STDIO UDP-LISTEN:6666

Have fun with your dockstar
