How to configure ftp server on QNX 7.1 with PAM user authentication

Create empty folder, I am using vm12

C:\> cd \
C:\> mkdir vms
C:\> cd vms
C:\vms> mkdir vm12
C:\vms> cd vm12

Bootstrap the VM, this creates a VirtualBox VM. Note that you have to install VirtualBox on this computer

C:\vms\vm12>C:\qnx710\host\win64\x86_64\usr\bin\bash C:/qnx710/host/common/bin/mkqnximage --noprompt --hostname=vm12 --type=vbox --arch=x86_64 --build

Update system_files.custom

C:\vms\vm12>nvim C:\vms\vm12\local\snippets\system_files.custom

Below contains more than just FTP but lines 5 to 21 are for FTP server

	# local/snippets/system_files.custom
	# Placeholder for local list of files to add to system partition
	lib/libpci.so.2.3=lib/libpci.so.2.3
	lib/libpci.so.3.0=lib/libpci.so.3.0
	xbin/inetd=usr/sbin/inetd
	xbin/telnetd=usr/sbin/telnetd
	xbin/ftpd=usr/sbin/ftpd
	etc/inetd.conf={
	telnet stream tcp nowait root /system/xbin/telnetd in.telnetd
	ftp stream tcp nowait root /system/xbin/ftpd in.ftpd -c /system/etc
	}
	[perms=444] pam/config/ftpd = {
	auth requisite pam_qnx.so
	account requisite pam_qnx.so
	session requisite pam_qnx.so
	password requisite pam_qnx.so
	}
	etc/ftpusers={
	root allow
	qnxuser allow
	}

Update ifs_files.custom to sym link /system/xbin/login to /bin/login

	# local/snippets/ifs_files.custom
	# Placeholder for local list of files to add to ifs
	[+script] .script = {
	procmgr_symlink /system/xbin/login /bin/login
	}

Update post_start.custom to start super server (inetd)

	# local/snippets/post_start.custom
	# Commands executed from post_startup.sh. Executed at the end of system startup whether slm is in use
	# or not
	#
	# To allow resource managers to be run properly with and without security policies, command lines
	# should be written in one of the following forms:
	#
	# START(resmgr_t) resmgr DROPROOT(resmgr_uid)
	# STARTU(resmgr_t, resmgr_uid) resmgr
	# Where resmgr_t is the security type name (arbitrary but usually the name of the resmgr with _t appended),
	# and resmgr_uid is the id to use for both uid and gid. DROPROOT is used only in cases where the
	# resource manager supports a -U option for switching to non-root.
	inetd -D /system/etc/inetd.conf

Rebuild and run the VM, like:

C:\vms\vm12>C:\qnx710\host\win64\x86_64\usr\bin\bash C:/qnx710/host/common/bin/mkqnximage --noprompt --hostname=vm12 --type=vbox --arch=x86_64 --build --force --run
