In our application, we would like to control FTP and TELNET access to a
QNX4.24 machine. That is:
- Restrict FTP and Telnet access to only one or a few IP addresses.
- Prohibit one of the two Intel 82557 compatible ethernet cards on this
machine from granting ftp and telnet access( i.e. ftp and telnet access are
allowed on one port only)
I have Net started, and the two Net.ether82557 drivers running
I have Socket started, ifconfig configured en1 and en2 (for ethernet cards 1
I have inetd controlling the ftpd and telnetd processes.
According to QNX knowledge database ref no QNX.000009648, there are two
files (/etc/hosts.deny and /etc/hosts.allowed) that are used to enforce 1.
However, I failed to make that work.
Is there something I should add in the inetd.conf file to make ftpd and
telnetd use these two files?
Does someone have a more detailed description of these two files and how
As for item 2, I didn’t find anything on the QNX web site and newsgroups.
I would really appreciate any solution or information
