Telnet going down?

QNX Newsgroups (Archives) qdn.public.qnxrtp.os
#1

I have RTP installed on your basic Compaq. It generally works well. Most
of the work I do on the system is done via a telnet connection. It
appears that inetd, or something related to network services, goes down
under circumstances I don’t understand.

What I observe is that Neutrino will sometimes stop responding to
requests to initiate telnet sessions. When this happens, existing telnet
sessions will be closed and no further sessions will be startable until
the system is rebooted. I suspect that killing some process and
restarting may be sufficient, but I haven’t tried to figure out if it is
or which processes those would be.

Sometimes other tcp services (e.g. ping responses) will go down with
telnet. Usually, I am able to find that io-net has dumped core when this
happens, although I don’t know how to get useful information from a core
file for io-net.

I’ve not been able to find any reasonable correlation to any other
network activity which may trigger these behaviors. Has anyone else seen
behavior similar to what I’m seeing? Does anyone have a suggestion of
what may be happening or how I might get Neutrino to help me figure out
why it doesn’t like my network?

Thanks in advance,
Eric

Can you describe which network services you’re using.

  • which driver(s)
  • which stack
  • qnet?
  • ppp?

I don’t know which driver is controlling it (and I’m not sure how to
figure that out) but the ethernet card is from Accton Technology Corp.
From “pci -v” (at a time when the system is properly functioning):

Class = Network (Ethernet)
Vendor ID = 1113h, Accton Technology Corporation
Device ID = 1211h, Unknown Unknown
PCI index = 0h
Class Codes = 020000h
Revision ID = 10h
Bus number = 0
Device number = 4
Function num = 0
Status Reg = 200h
Command Reg = 7h
Header type = 0h Single-function
BIST = 0h Build-in-self-test not supported
Latency Timer = 42h
Cache Line Size= 0h
IO Address = 2000h length 128 enabled
Mem Address = 50900000h 32bit length 128 enabled
Subsystem Vendor ID = 1113h
Subsystem ID = 1211h
Max Lat = 64ns
Min Gnt = 32ns
PCI Int Pin = INT A
Interrupt line = 10

In terms of “network services”, I am using th inetd.conf from the RTP
installation. I have not modified it. For that matter, I haven’t changed
any of the default configuration files.

  • which stack

I believe I’m using the tiny stack. io-net is started with the following
arguments:

io-net -pttcpip -ppppmgr -drtl pci=0

  • qnet?

I am not using qnet.

  • ppp?

I am not using ppp. All my network is through a 10BaseT hardwire into my
LAN (and, thereby to the rest of the world). The machine has a static IP
address (i.e. not DHCP).

Does this help suggest what may be happening?

The tiny stack in patch A fixes a bug where connection requests
on a particular port would be ignored after a dup SYN was received.
This could explain why telnet requests sometime are ignored.
Slaying and restarting inetd should fix this until the patch is
released, or you could run the large stack.

As to why io-net is core dumping, I’m not sure yet. The info
you provided helps narrow it down a little.

Continuing the informational data dump, telnet “went down” last night.
As it usually does, it also took down all tcp stuff (telnet, ftp, ping,
the works, nothing gets either in or out of the box). After the work
locked up (and before I restarted the machine to fix the problem), I
captured a few pidins (pidin ar, pidin mem, and pidin). These may
provide some insight. If this gives you any other clues or if you want
more info, let me know – telnet seems to have a half-life of about a
day, so it’s pretty easy to run more autopsies.

So, one should be able to slay inetd and restart it? I’ll give that a
try next time.

I look forward to patch A.

Thanks,
Eric

I think I’ve found something in the rtl driver. I don’t think
the inetd thing will work.

You can download the latest devn-rtl.so from
http://www.qnx.com/~cdm if you want to give it
a try.

FYI: I pulled this down and installed it as soon as I saw your note
(circa the 18th). I have seen zero recurrences of the “telnet hang” I
was seeing previously. The previous MTBF was 30 hours, so this is a
great improvement. Thanks!!
