[jcifs] No Access Exception Question

[Yibo Dong]

Hi, Mike,

Thanks for checking it for me. No, I am not running on a laptop without
an ethernet card attached. ydong is a desktop machine on our LAN.

I am getting a different error now. Here is what I used:

Server:

createnp \\.\pipe\name

Client:

java CallNamedPipe -Djcifs.properties=jcifs.prp inFile.txt outFile.txt

Jcifs.prp Content:

domain=                  /* left blank since we don't have one */
username=ydong
password=MyPassword
;wins=143.232.153.176    /* IP address for ydong */
wins=143.232.153.176     /* ditto */
;log=ALL
;resolveOrder=WINS
;soTimeout=3000

Error I Am Getting:

jcifs.smb.SmbException: Invalid parameter 	at
jcifs.smb.SmbTransport.sendTransaction(SmbTransport.java:628) 	at
jcifs.smb.SmbSession.sendTransaction(SmbSession.java:123) 	at
jcifs.smb.SmbTree.sendTransaction(SmbTree.java:65) 	at
jcifs.smb.SmbFile.sendTransaction(SmbFile.java:456) 	at
jcifs.smb.TransactNamedPipeOutputStream.write(TransactNamedPipeOutputStream.
java:62) 	at CallNamedPipe.main(CallNamedPipe.java:50) Exception in thread
"main"

It's not clear to me which parameter is invalid.

Interestingly, if I re-run the client at this point, I will get an
timeout error saying YDONG/143.232.153.176 is not responding, but if
I try to re-run createnp, I will get a 231 (pipe busy) error. I have to
reboot the machine in order for createnp to work again.

Thanks again for helping me.

-Yibo

I  just  went through the CallNamedPipe example and it worked. You know you
will  need  to  supply appropriate authentication creadentials. It's pretty
standard  for  GUEST  to  be  disabled  these  days. If you run the example
without  them  you  indeed  get  AccessDenied (natrually). When you run the
callnp.exe example it works because it uses your creadentials from the LSA.
Try:

  java CreateNamedPipe smb://ydong:mypass@host/IPC$/pipe/foo input output

Or use -Djcifs.properties=jcifs.prp and make a jcifs.prp with
username=ydong, password=mypass, ...etc.

If this is not your problem then there might be a Win2K specific issue. Are
you using a Laptop without an ethernet cable attached?

Right, /P 0x6.
