Hi:
I have connected a computer and the labtop with a hub. The computer is
running on win2000 and the labtop is running QNX 4.25. When the comptuer
accessing labtop, it runs just fine. But when it wants to access telnet and
FTP, it is sluggish and I need to wait for minutes in order for it to
connect. Can you suggest a way to fix this? Thanks.

You need to have the DNS working or an entry in the hosts file so it doesn’t
need to wait to timeout.

Do you mean uncomment the line 10.2 and 10.3? If not, what entry is needed?
Thanks for your help.

Why did you remove the /etc/resolv.conf file? The sluggishness is probably
due to the requirement to timeout on every DNS name lookup (since you’ve
just removed the file that says how to do it).

You can put host IP mappings in your /etc/hosts file, but some applications
will want to do a reverse lookup, and that will take a while to timeout.
What was the original problem before you removed /etc/resolv.conf - perhaps
there are better ways of solving or working around the original issue.

You’ll have to be more specific about “sluggish”. What is sluggish about
ftp or telnet? Is it the login/connect time? If so, this is probably a
reverse nameserver resolving issue (ie. the nameserver the qnx4 box thinks
it needs to use has a route, but isn’t on the network/not responding). If
it’s just transfer speed, then something else is the problem. Is the
phindows session idle (ie. not redrawing anything etc), when you’re doing
ftp/telnet.

It is the transfer speed that is having a problem. Phindow is working fine
while telnet and ftp are working slowly. When telnet or ftp, we did not

Hi:
The problem is after removing /etc/resolv.conf, yes the speed when accessing
QNX4 using window via telnet and ftp is faster, but phindow doesn’t work
anymore. Currently we have set up so that QNX 4 will act as server, and our
goal is any computer can access to this server in any university campus
location. We want all telnet, ftp, and phindow to be able to access QNX 4
from window without any sluggish problem. The sluggish in the trasnfer
rate, for some reason, only occurs to ftp and telnet and not phindow (this
is when /etc/resolv.conf is NOT removed). As a result, is there any way to
increase the speed of telnet and ftp with taking the line out and that all
telnet, ftp and phindow will work fine? Thanks,

OK, maybe I should re-explain, so you can decided what to do…
The problem you are seeing, telnet/ftp into a QNX4 box need to wait
“minutes” to get a prompt, is cause by:
When telnetd/ftpd on QNX4 started to response the incomming request,
they usually need to do a “reverse name lookup” on the request. That is,
they look at the request, knowing which IP it is come from, and then
try to resolve the IP into a hostname.
How to resolve an IP into a hostname, is based on how name resolver
works. It either check the /etc/resolv.conf and ask the nameserver; or
it looks into /etc/hosts to see if there is a match. Should it look in to
the
/etc/hosts first, or should it talk to a nameserver first, is controled by
the
"lookup " keyword in /etc/resolv.conf (check menu for that). By default,
it goes to nameserver first.
Now the typical causing of your satuation is, you set up the
/etc/resolv.conf,
the telnetd/ftpd will then take your window BOX’s IP to the nameserver.
AND the nameserver if not properly setup for reverse resolving (a ip
to a name). It takes “minutes” for telnetd/ftpd realize the nameserver is
not going to answer, and timeout, and go check /etc/hosts, and then give
up the resolve, goes ahead to services you.
By remove the /etc/resolv.conf, telnetd/ftpd will notice they don’t have a
nameserver to talk to, and go check /etc/hosts, and give up immediatly,
which makes you “fell” the problem is solved.
However, you noticed this is not the proper way to manage a QNX box
in a big network. Like phindows may not works, “ping yahoo.com” from
the QNX box probably not going to work, because it can’t resolve the
name anymore …
If you have the control of the nameserver, fix it so it can do reverse
resolve properly. Otherwise, your chance is put “lookup file bind”
in /etc/resolv.conf, the resolver will look into /etc/hosts FIRST,
and you put all those windows’ box into your /etc/hosts, so that
the resolver can reverse resolve through the /etc/hosts, and no
need to goto nameserver.
Hopefully this explained everything…

It’s the traffic that’s slow, not the initial connection to telnet/ftp - at
least that is my understanding.
My understanding is:
Does this sluggish behaviour occur from all windows boxes? Does it occur if
you’re ftping from the QNX4 box out to another box? If you have another
QNX4 node on the network, do transfers between QNX4 nodes via FLEET or ftp
also seem sluggish. Has anything been added to your network from the last
time things worked properly? Have you checked your network to see if
someone is using the same IP address by accident?
Please post a sin and a ser ver of your QNX4 system.

Hi:I have connected a computer and the labtop with a
hub.
The
computer

running on win2000 and the labtop is running QNX
4.25.
When
the
comptuer
accessing labtop, it runs just fine. But when it
wants
to
access
telnet
and
FTP, it is sluggish and I need to wait for
minutes

Hi:
I found out that the initial slowing is caused by a bad wire. Now it’s
fixed. Yet, the problem switch to the slowing of inital connection to
telnet/ftp. You ask me to post a sin, do you think that the priority would
have contributed in this problem?

It’s the traffic that’s slow, not the initial connection to telnet/ftp -
at
least that is my understanding.My understanding is:
- /etc/resolv.conf removal was a red herring, it has nothing to do with
the problem (unless it’s a connection time issue, which it isn’t).- For some reason ftp/telnet seem to experience sluggish behaviour, but
phindows does not.Does this sluggish behaviour occur from all windows boxes? Does it occur
if
you’re ftping from the QNX4 box out to another box? If you have another
QNX4 node on the network, do transfers between QNX4 nodes via FLEET or ftp
also seem sluggish. Has anything been added to your network from the last
time things worked properly? Have you checked your network to see if
someone is using the same IP address by accident?Please post a sin and a ser ver of your QNX4 system.

OK, maybe I should re-explain, so you can decided what to do…The problem you are seeing, telnet/ftp into a QNX4 box need to wait
“minutes” to get a prompt, is cause by:When telnetd/ftpd on QNX4 started to response the incomming request,
they usually need to do a “reverse name lookup” on the request. That is,
they look at the request, knowing which IP it is come from, and then
try to resolve the IP into a hostname.How to resolve an IP into a hostname, is based on how name resolver
works. It either check the /etc/resolv.conf and ask the nameserver; or
it looks into /etc/hosts to see if there is a match. Should it look in
to
the
/etc/hosts first, or should it talk to a nameserver first, is controled
by
the
"lookup " keyword in /etc/resolv.conf (check menu for that). By default,
it goes to nameserver first.Now the typical causing of your satuation is, you set up the
/etc/resolv.conf,
the telnetd/ftpd will then take your window BOX’s IP to the nameserver.
AND the nameserver if not properly setup for reverse resolving (a ip
to a name). It takes “minutes” for telnetd/ftpd realize the nameserver
is
not going to answer, and timeout, and go check /etc/hosts, and then give
up the resolve, goes ahead to services you.By remove the /etc/resolv.conf, telnetd/ftpd will notice they don’t have
a
nameserver to talk to, and go check /etc/hosts, and give up immediatly,
which makes you “fell” the problem is solved.However, you noticed this is not the proper way to manage a QNX box
in a big network. Like phindows may not works, “ping yahoo.com” from
the QNX box probably not going to work, because it can’t resolve the
name anymore …If you have the control of the nameserver, fix it so it can do reverse
resolve properly. Otherwise, your chance is put “lookup file bind”
in /etc/resolv.conf, the resolver will look into /etc/hosts FIRST,
and you put all those windows’ box into your /etc/hosts, so that
the resolver can reverse resolve through the /etc/hosts, and no
need to goto nameserver.Hopefully this explained everything…

Hi:The problem is after removing /etc/resolv.conf, yes the speed when
accessing
QNX4 using window via telnet and ftp is faster, but phindow doesn’t
work
anymore. Currently we have set up so that QNX 4 will act as server,
and
our
goal is any computer can access to this server in any university
campus
location. We want all telnet, ftp, and phindow to be able to access
QNX
4
from window without any sluggish problem. The sluggish in the
trasnfer
rate, for some reason, only occurs to ftp and telnet and not phindow
(this
is when /etc/resolv.conf is NOT removed). As a result, is there any
way
to
increase the speed of telnet and ftp with taking the line out and that
all
telnet, ftp and phindow will work fine? Thanks,Seddrak

Removing /etc/resolv.conf should not have any effect on transfer
speed,
only
initial connection establishment. Have you tried connecting the
Windows
and
QNX4 box via cross over cable? See if that results in any transfer
speed
change.-Adam

It is the transfer speed that is having a problem. Phindow is
working
fine
while telnet and ftp are working slowly. When telnet or ftp, we
did
not
open phindow, so it doesn’t matter, right? or is there some
command
we
need
to set in phindow? thanks.seddrak’

The big picture is:I have a computer running in QNX 4.25 and working as a server.
Another
computer running window 2000 installed phindow, ftp and
telnet.
Before
removing /etc/resolv.conf, accessing the server via phindow is
fine,
but
accessing via ftp and telnet is extremely slow. I was
wondering
if
there
are some ways to improve the system so that all three
accessing
equipment
will run smoothly without any sluggish problem.Thanks,

I found out that the initial slowing is caused by a bad wire. Now it’s
fixed. Yet, the problem switch to the slowing of inital connection to
telnet/ftp. You ask me to post a sin, do you think that the priority
would
have contributed in this problem?
The sin was to get some introspection on your system (ie. what is running,
etc). Now if the transfer speed issue is gone, and we’re back to an intial
connection issue - then it’s most likely a name resolving issue. The qnx4
box is probably trying to do a reverse name lookup on the IP of the Windows
box. If the name server being used isn’t available or responding this could
take a minute to timeout. If you add the IP address of the Windows box,
into the /etc/hosts file on the qnx4 node, does it make a difference?

Hi:
I have resolved the slowing connection problem. Thanks. There is one more
twist:
Through Pindow, we only want the window client to be able to access a folder
in the qnx box. In other words, there will be a folder under /home
allocating for the window user. The window box should only be allowed to
enter this folder directly, without the ability to see other folders. What
we did is to “passwd test”, so the folder test will be under home with a
password. The problem is when pindow from window is accessing the qnx, it
will go in from the root directory, and it can access to all folders under
the qnx box. What should I do so that only the folder test can be accessed?
Thanks,
Seddrak
