[PATCH] shell: Add a ping command.
This patch adds a ping command to the RTEMS shell. It pings for a count of 5 or so and then stops because there is not ^C in the RTEMS shell. A flood ping also works with the -c option. As stated in the commit message some options work and some do not and I suspect the age of our TCP/IP stack is the reason. I have added doco to the patch but I have not built the doco because of the hassle on MacOS. This code needs to be changed to not use select and so avoid the issue of more than 64 fd's open. ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
[PATCH] shell: Add a ping command.
The ping code is taken from a recent FreeBSD release. Some options have been
tested, other not tested or do not work. This could be due to the age of
our TCP/IP stack.
This version of ping will not work if more than 64 file descriptors are
open at once because the select FD size is 64 as set in newlib.

[PATCH] libmisc: Add a stdio redirector helper.
This module makes it easy to redirect and capture stdout, stderr or any
other fd in your application.
The captured data can be sent off board, for example using syslog,
or buffered and displayed in a web page.

ls broken in shell.
Hello, It looks like 'ls' is broken in the shell. On sparc/sis running fileio, selecting 's' for shell, logging in and then 'ls' exits the simulator. I saw this with mksh and assumed something was not working with mksh however this now looks like something in 'ls'. With mksh I traced the fault to the heap free call in mksh that failed on the heap check. I have not looked into the fileio failure.

Re: ls broken in shell.
Time for your wrapper call generator. Wrap malloc and free. Cod easily be freeing something that was never allocated or a pointer that was incremented. Another guess is a pointer that was not initialized to NULL and ls thinks it should be freed.

Hmmm getting automake and friends to support a trace link ... I have some things on between now and the end of the year. ;) Another guess is a pointer that was not initialized to NULL and ls thinks it should be freed. The check failed in a free call from memory in the mksh it released after ls returned. It was like something corrupted the memory. I have not looked at the fileio example and have no time at the moment so just raised the issue. Chris ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
