Amit,
First, I suggest you change
PRINC = "4"
to
PRINC := "${@int(PRINC) + 1}"
This way your bbappend will always increment the PR to one more than the PR
called out by the main recipe. So if the openssh recipe would get updated and
increment the PR, you do not have to change your bbappend.
Change
SRC_URI = "file://banner"
To
SRC_URI += "file://banner"
The += appends your banner file to the SRC_URI for the openssh recipe. With
your line, you are overriding all the SRC_URI for the entire openssh recipe and
the openssh recipe will only include the banner file. I've taken to the habit
of writing the SRC_URI as follows:
SRC_URI += " \
file://banner \
"
just to ensure that words aren't joined together when my SRC_URI is appended to
the existing one. I don't know if this is strictly necessary, but it's not a
bad habit.
Change
FILESEXTRAPATHS_prepend := "${THISDIR}/openssh-6.1p1:"
to
FILESEXTRAPATHS_prepend := "${THISDIR}:"
so Bitbake can find your banner file and sshd_config that you have in the same
directory as the bbappend.
I can't remember if you get a warning if Bitbake can't find the license file at
all or if it fails on each attempt through the filepath. Since your new path
is first, it won't find LICENCE in your layer since you didn't copy it. Once
way to quiet this warning would be to copy the license file to your directory.

Hi Brayan
Thanks for your help
The way I modify .bbapend file is below
PRINC = "4"
SRC_URI = "file://banner<file:///\\banner>"
FILESEXTRAPATHS_prepend := "${THISDIR}/openssh-6.1p1:"
do_install_append() {
Install -m 755 ${WORKDIR}/banner ${D}${sysconfdir}/ssh
}
But it gives me
Below problem
WARNING:
/tmp/work/cortexa15hf-vfp-neon-poky-linux-gnueabi/openssh/6.1p1-r3/openssh-6.1p1/LICENCE
could not be copied for some reason. It may not exist. WARN for now.
And my build process is really got slow and sometimes I am getting the error
also
What could be the reason for above??

install -d ${D}${sysconfdir}/ssh
install -m 0644 ${WORKDIR}/banner ${D}${sysconfdir/ssh/banner
}
PRINC := "${@int(PRINC) + 1}"
then place your banner file and sshd_config in the same directory as your
bbappend. When openssh gets built, Bitbake will find your sshd_config first
and use and install that file instead of the one from the main layer. The
recipe also tells it how to handle the new banner file that is not part of the
original recipe; you do not need to put these rules in place for sshd_config
because that is already part of the original recipe. Then in the future every
time you make a change to the openssh package in your layer, increment the
PRINC so your package management tools will see it as an upgrade. For example,
if you change the contents of the banner file, then change the "+ 1" to "+ 2".

I am new to OpenEmbedded Yocto and have a requirement where OpenSSH pre login
banner
should come when do ssh from target board
Now I know I have to create a simple .txt file(banner) and put my banner in to
it and add the following to sshd_config
Banner /etc/ssh/banner
But now wanted to know where should I keep my banner file in yocto so that
Yocto build infrastructure will pack banner file to /etc/ssh/banner into final
image.
I do have receipes for openssh in meta-xyz/recipes-connectivity/openssh folder
Thanks
Amit
