[Dpcl-user] Re: user problem

[Dave W. <dwo...@us...>]

Once DPCL is installed, any user on the system should be able to use it.
There is no need to install more than once per system.

What error is the second user getting?

An obvious problem is that each user must have a .rhosts file in their home
directory on the node where they want to connect to a target application
(hello) specifying the node they are connecting from (eut_hello). If
rlogin, rsh or similar commands work between two nodes, then this is likely
not the problem.

Do you have the same copy of DPCL installed on both systems?

In particular, you had made a change to DPCL as follows

convert the host address to a useful (character)
format.
    sprintf(this->ip_addr, "0.0.0.0",
        he->h_addr_list[0][0],
        he->h_addr_list[0][1],
        he->h_addr_list[0][2],
        he->h_addr_list[0][3]);


change it to this:

   // convert the host address to a useful (character)
format.
    sprintf(this->ip_addr, "0.0.0.0",
        he->h_addr_list[0][0] & 0xFF,
        he->h_addr_list[0][1] & 0xFF,
        he->h_addr_list[0][2] & 0xFF,
        he->h_addr_list[0][3] & 0xFF);

Is this code the same on both systems? If not, can you try with it on both
systems? I have not had the time to look at the change in detail, and am
not convinced the change is required. But without any other information, it
might be worth a try if it's not too much trouble.

Is there any sort of software (firewall or routing software for instance)
that could make communicating between the machines fail? Can you ping from
one machine to the other, and also rlogin from one to the other (both ways)
without problems?

Unfortunately, the log files did not get attached to the email. Can you
send the logs again?

Also, I suggest you ail to dpc...@os... (our dpcl mailing
list) since if I am out of the office or busy for some reason, other
developers can see the email. If you are not comfortable with doing that,
of course you can email me directly,

Dave

Hi Dave:
   I am sorry for send you a empty just before.
My question is when I installed dpcl rpm package, I
can run hello and eut_hello. but another user can't
run it. Do every user need to install and build dpcl
respectively? Whether they can share the same rpm
package? How to do it?

   Another question, I try to connect hello between
pact06 and pact07, but it didn't succeed. when I try
to connect hello runing on pact07 from pact06, the
eut_hello blocked, then I use Ctrl+C to terminate it.
Then I try to connect hello running on pact07 from
pact07,the error message is:

Connecting to process 12360 on node pact06
client: server 'pact06' terminated, removing socket 4.
bconnect error ASC_communication_failure.

By the way, I can run eut_hello to connect hello on
both local machine.

I attach to log file of the running result.
dpclsd.27625 is on pact07 and dpclsd.12314 is on
pact06.

Would you please give me some advice?

     regards
         -Wei
