Getting version of rtems, and writing files

So I think I found the source, there is no ikup command when I am telnet'ed
There is a mount command it seems but I have no idea how to use it, ones
suggestion of using it as:
mount -t nfs foo:/bar /net
fails but calling mount("something") fails differently:
I am not sure what all the numbers mean from the returning values items
alt-rotator>mount -t nfs 10.50.1.1:/test /test
Cexp syntax error: syntax error, unexpected IDENT
I also goofed (already) and when I mkdir test i forgot the quotes
so I put mkdir(test) and created something I cannot seem to remove :/ .
(the UWVS?? etc)
2, 2948b, 0.0 00755 dev/
16, 16384b, 0.0 00000 apo/
12959797, 4096b, 501.501 00775 rtems/
16, 0b, 0.0 00000 UWVS???l$4?|$8??t$<?
17, 0b, 0.0 00000 test/
And to the question:
- Can you say what the board support package and application are?
I am not sure what specifically you mean here, in the folder I found the
source code (it was messy) i found all these other folders which might be
packages compiled to it? and the README said to use the rtems-4.7.1 folder
(where the code is)
[root at devel1 tools]# ls
build-4.6 cexp-1.5-4.6 ntp-4.1.1a-rtems-20030127.tar rtems-18.104.22.168.APO
build-4.7 cexp-1.5-4.7 openntpd-3.9p1 rtems-22.214.171.124.ORIG

rtems-4.7.1.APO-Network-Mod RTEMS-GeSys_2.1.beta-4.7 temp
Sort of progress, just not sure how or where :D and totally sad I seemed to
of created a corrupted file on the fs.
