Samba error : "open_sockets_smbd: accept: No buffer space available"

[RNC]

Hello all,

I have SAMBA version: smbd version 3.0.7 based HP CIFS Server A.02.01.02 started, on hp-ux 11.11, and when i probe to connect i recive the next error in /var/opt/samba/log.smbd:

[2007/09/24 16:35:47, 0] smbd/server.c:open_sockets_smbd(382)
open_sockets_smbd: accept: No buffer space available


Someone can help me?

Thanks in advanced

The resource requirements of the CIFS A.02.xx.xx are different from its earlier versions. I would check the syslog.log file for any system related messages while trying to connect. There are few kernel parameters requirements like nfile, nproc etc. Refer the CIFS Admin guide.

Now i modified the parameters like say in the document and i can't connect since the windows pc, and i obtain the next error in the log.winbindd :

In any case, now the problem is, i have all configured correct, and i connect in my pc to access to the folder in the unix, but:

1.- I recive the window for insert user and passwd
2.- I insert the correct user and passwd
3.- I continue receiving the window for insert the user and passwd and i no recive the folder

I don't know it you have checked this, but look into the smb.conf for configuration options for winbind:


# specify the uid range which can be used by winbindd to allocate uids for Windows users as necessary
winbind uid = 10000-65000

# specify the uid range which can be used by winbindd to allocate uids for Windows users as necessary
winbind gid = 10000-65000

# Define a home directory to be given to passwd(5) style entries generated by libnss_winbind.so. You can use variables here
winbind template homedir = /home/%D/%U

#Specify a shell for all winbind user entries return by the libnss_winbind.so library.
winbind template shell = /bin/sh

Hi RNC,

You are failing user/password authentication. First, upgrade your CIFS Server version to avoid the "buffer space" problem - that was fixed in an earlier release. Get A.02.03 at software.hp.com. Next, with the default log setting in smb.conf you will get a file /var/opt/samba/log.clientname. Set the "log level = 3" and try your logon, then look in the log file to see where it is failing. If you cannot see where it is failing, post for smb.conf here and a few lines from the log file that include the username and the error text (search on "failed" or "error").

Hi all,

I resolved the problem in this way, i write if is possible to use for other that had the same problem:


1) In the [global] insert
encrypt password=yes
2) Execute with the user that you need (the same in the server that you use to connect)
smbpasswd −a

Bye.
