I would like to enable FTP support on my 7.0 and 7.1 VM targets. How can I achieve this?

Recommendation

7.0 Solution:

FTP resources (binaries, libs, config files) are included in prebuild 7.0 VM that is available in QNX Software Center: QNX SDP 7.0 x86-64 virtual machine for VMware

To enable FTP, make the following modifications:

Uncomment the two FTP lines in inetd.config
Allow preferred user/users in ftpusers
Run: inetd

--------------------------------------------------------------------------------

7.1 Solution:

FTP resources (binaries, libs, config files) are not included in the generated 7.1 VMware images that you can create in Momentics or by running mkqnximage.

The following describes one approach to get FTP working in 7.1:

Source 7.1 environment
In an empty folder, Run: mkqnximage --type=vmware
Go into /local/snippets and make the following modifications:

Data_files.custom, ADD:

[gid=0 uid=0 perms=644] var/etc/ftpusers = {
root allow
}

>>> Post_start.custom, ADD:

inetd /system/etc/inetd.conf &

System_files.custom, ADD:

xbin/telnetd=usr/sbin/telnetd
xbin/inetd=usr/sbin/inetd
xbin/ftpd=usr/sbin/ftpd
[gid=0 uid=0 perms=444] pam/config/ftpd={
# The PAM configuration file for the 'ftpd' service

auth requisite pam_qnx.so

account requisite pam_qnx.so

session requisite pam_qnx.so

password requisite pam_qnx.so
}
etc/inetd.conf={
telnet stream tcp nowait root /system/xbin/telnetd in.telnetd
ftp stream tcp nowait root /system/xbin/ftpd in.ftpd -l
}

NOTE: When you FTP to the 7.1 VM (i.e. a VM generated using Momentics), you may notice that attempts to run "ls" do NOT list the contents of the folder. The only thing you see is:

229 Entering Extended Passive Mode (|||65473|)
150 Opening ASCII mode data connection for '/bin/ls'
226 Transfer complete

HOW TO FIX: ftp needs "/bin/sh". The 7.1 VM does not have "/bin/ls". It has "/system/xbin/ls". You can modify output/build/ifs.build to include:

procmgr_symlink /system/xbin/ls /bin/ls
