ping problem in new vxWorks 6.6
vadik
I have a fresh vxWorks 6.6 image .
I have ethernet interface configured and I receive from ifconfig the
following:
lo0 Link type:Local loopback Queue:none
...
lltemac0 Link type:Ethernet HWaddr 06:05:04:03:02:01
Queue:none

from hostShow :
hostname inet address aliases

localhost 127.0.0.1
vxTarget 150.60.8.8
host 150.60.8.9
But when I try to ping :
ping "150.60.8.9"
Pinging host (150.60.8.9) with 64 bytes of data:
Request timed out: Operation would block (70).
Request timed out: Operation would block (70).

Host unreachable received from 150.60.8.8

4 packets transmitted, 0 received, 100% packet loss, time 4000 ms

What am missing here ?

Wow, I fought this problem for a long time with 6.6 on the ads8572.
Debugged way down into the stack code and never figured it out.
Then moved to vxWorks 6.7 and it magically worked.
If you can upgrade, try that.

Thank you for the suggestion, meanwhile I figured it out.
lltemac defaulted to 1000 Mbps while my connection was only 100 Mbps,
once I configured lltemac to work with 100 Mbps it is working .

Thanks for sharing the solution.
It may be my problem was the same cause.
I think this is the sort of thing auto-negotiation is supposed to sort
out -- right? ;-)

Hi,
Even I am facing a similar issue with VxWorks 6.5 with the the Network
Stack 6.6 Backported. Can you give me a little more details as to how
you narrowed down to the problem being that of the Ethernet Speed and
how you got around the same.
Thanks and Regards,

Hi,
Though you would have got ur answer but i thought to share this info
as it cud b useful to others if not u.
u were trying to ping the host IP addr from the target/host shell.
All u need to do is to include the below components in the kernel:
(a) INCLUDE_PING
(b) network show routines (must) and all other show routines like
ICMP, TCP, UDP (depends)
(c) INCLUDE_ROUTEC
Execute the commands in the order:
(a) ifconfig
(b) ifShow
(c) routec("add -net host ipaddr target ipaddr");
(d) ping "host ipaddr",4
Hope its useful. Incase u need the exact commands, let me know.
Regards,
Swaroop

On 6.5, I can ping (ICMPv4) the host but ping6 returns the same error
messages:
Pinging 2002:1:2:3::2 (2002:1:2:3::2) with 64 bytes of data:
Request timed out: Operation would block (70).
Direct cable (also tried crossover) to a Windows XP host.
Any suggestions appreciated.

use the class for giving IP address.
if you are using ethernet cable use 169.254.245.102 this class for host and target as well.
if you are using with internet use 192.168.0.102.
Thanks
