[U2] UniData 6.1 and unirpcd problems.

Fri, 17 Sep 2004 11:48:53 -0700

Sorry for the long post and to keep pestering the group on this, but I'm still trying to get a UniObjects connection to work.
I was using UniVerse PE, but now I'm trying UniData 6.01, downloaded from IBM's website. The product grid says 7.2 is ok.

I put together a clean Linux box with RH7.2 and UniData 6.01, and I'm once again trying to get a UniObjects connection working. Previously (with UniVerse) I was getting a "user name provided is incorrect" error.

Here's the java code used to connect with:
   String user="uduser";
   String passwd="udpass";
   String host="192.168.0.250";
   String acct="/home/uduser";
   UniDynArray rec=new UniDynArray();
   UniString sRec=new UniString();

   try {
     UniSession session=new UniSession();
     session.setUserName(user);
     session.setPassword(passwd);
     session.setHostName(host);
     session.setAccountPath(acct);
     session.connect();

Now I'm getting a "asjava.uniobjects.UniSessionException: No RPC Connection active." message.

So I look to see if port 31438 is open:
# netstat -a | grep tcp
- - - - -
tcp        0      0 *:uvrpc                 *:*                     LISTEN
- - - - -
Yup.

So I check to see if UniData is running:
showud
     USER     PID    TIME COMMAND
     root     998    0:00 /usr/ud60/cleanupd -m 10 -t 20
     root     993    0:00 /usr/ud60/sbcs -r
     root     987    0:00 /usr/ud60/smm -t 60
     root    1013    0:00 /usr/unishared/unirpc/unirpcd

Sure looks like it.

So I stop unirpcd and restart it in debug mode:
unirpcd -d9 > /tmp/rpc.out 2>&1 &
then
tail -f /tmp/rpc.out

Output:

I can telnet in as "uduser" and get in.
I can telnet to port 31438 and get the expected response:

telnet 192.168.0.250 31438
Trying 192.168.0.250...
Connected to 192.168.0.250.
Escape character is '^]'.

I don't know what to check next. I'm not firewalling this box, and I am apparently using MD5 password encryption. I have not been able to find how to use DES encryption on a RH box.

Any ideas?
