Then you are not running a 'standard shell', but some sort of local
hack and/or wrapper:
kobe-> ssh server "echo 'hello world' > foo"
kobe-> ssh server "od -c foo"
0000000 h e l l o w o r l d \n
0000014
kobe-> echo hello new world | ssh server "dd >> foo"
0+1 records in
0+1 records out
kobe-> ssh server "od -c foo"
0000000 h e l l o w o r l d \n h e l l
0000020 o n e w w o r l d \n
0000034
kobe->
I'm sorry, but I don't think you can get effective "help" from the
FreeBSD lists. You will have to ask for specific guidelines and help
from your hosting provider. Anything else will be guesswork and may
break without any sort of notice in the future, when your host decides
to install a "new" "security fix" to their custom shell.
