I have installed vsftpd and configured it for a ftp on extended storage in Openwrt router.
I have also installed "shadow-useradd shadow-passwd shadow-usermod and shadow-
common" to add and modify the user name and password. The problem is that i am
trying to add or modify the user name with atleast one uppercase letter, but with the
uppercase letter i'm getting the following error.
useradd: invalid user name Axx_01 usermod: invalid user name Axx_01
can anyone tell me is the shadow-useradd and shadow-usermod support creating the user name with upper case letter.
