QNX FTP Problem

[markwolfe Veteran]

I am having a problem where I am using wget via FTP to grab several files (around 20 files, total of 70-some KB in total) of production configuration data from some of our equipment (running QNX 4.24). The units are set with static IPs, and everything works well, in general.

However, after many (several hundred) downloads, the unit will stop communicating. I cannot connect via FTP (or telnet, etc.), and the unit will no longer ping. The interface seems to be down.

This unit has a very limited implementation of commands (as far as I can tell). ifconfig is there, but QNX doesn't use 'eth0' as the interface device. Nor are there any man pages on this thing. :(

I looked through Google, and qnx.com, and even sent an email to info@qnx.com (the best support address I could find on qnx.com). No response yet from the email...

Qnx.com does have some documentation of commands on their webpage, and I have gotten some syntax from this source. However, I need a bit of guidance to see what ethernet device name to use. Then I need to look to see what the status of the services are (their documents seem to indicate it uses ftpd as the server, but a failure here shouldn't stop telnet and pings).

Does anyone here have experience with QNX, and can point me in a few directions? I can poke around from there, but I feel a bit lost at this point.

P.S. I am a Linux user, so am comfortable with the command-line, but I am not an expert - just a familiar user.

Ok, I got the QNX system to drop its ethernet again by 'irritating' it. I ran the following from a Windows PC every 5 minutes to get a fresh download frequently (the downloading only takes a total of 20 seconds to run the script, so there is plenty of idle time between FTP activity sessions).

cd /home/cpflo/data/log/A
ascii
mget *.log
mget *.flt
mget *.pcc
bye

If anyone has suggestions, please let me know. This is our lab unit, so we can afford to leave this down for a while and do some checks.

Any help is appreciated. :D

Well, I have *still* not heard from QNX from my email. And, I was hoping on the off-chance that someone here was familiar enough with QNX to help (I knew it was a long-shot).

Let me try contacting QNX by phone, and see how good the Customer Service department on this commercial *nix is.

If anyone has any ideas in the future, I will keep an eye on this thread...

I have used QNX Neutrino for some time, but I don't have this problem myself. My ebst bet would be the network interface and its drivers.
