Samba issue: "session request failed"

Hi,

I am having a serious problem trying to get my linux box to send "net send" messages using smbclient.

Certain events trigger a bash script which will then "net send" messages to various computers on our network.

---------------------------------------------------------------------------

THIS IS THE SYNTAX I USE:

echo "test message" | smbclient -M pc1-bagu4-4-cust36.bagu.cable.ntl.com -I 81.97.21.36

THIS IS THE OUTPUT:

Serverzone is -3600

Has anyone got any ideas for this, I'm really starting to run out of ideas! I have trawled though google & groups but to no avail.

Any help would be REALLY appreciated.

Thanks Oliver

Someone must have a inkling? I would really appreciate it as im really lost for ideas!

hey, I see you are new to LQ, welcome, just as an observation, you shouldn't double post on different forums, or your thread will be closed by the moderators.

Ah thanks (oops) any ideas on the issue?

Hi,

One of my applications sends a "netsend" message to my computer using "smbclient -M" when a certain event is triggered, this worked fine on the LAN but on a external server it doesn't work...

>>What are the OS's trying to connect to the Linux machine?

I am not trying to *connect* to any machine just sent a net send message using SMBCLIENT -M.

One machine is Windows XP Pro and the other is Windows XP Home. I have tried a LAN "net send" message to make sure the machines are receiving the messages and they are.

I have also tried to send the message from an external Windows Server and again the message was received.

>>Can you post a copy of your smb.conf file?

Since posting the above message I have upgraded to RedHat 9. When I know send a "net send" message to port 135, this is the output:

-------------------------------

When I post to 137 (which is closed) I get the following error message.. (debug stripped)

error connecting to 81.128.1.198:137 (Connection refused)
Error connecting to 81.128.1.198 (Connection refused)
Connection to host81-128-1-198.in-addr.btopenworld.com. failed

-------------------------------

Which makes me think that when connecting to port 135 it actually connected then disconnect for some reason? Maybe it times out?

Does the protocol require some sort of handshake from the dest machine? Maybe my firewall blocks the ack and stops the full send?

These are just some brainstorms. Any help would really be appreciated.

Thanks in advance Oliver
