The new version of Samba/iX 2.0.7 is released as part of FOS MPE/iX 7.5. The Samba/iX 2.0.7 version of software resides inside the SAMBA account in HFS directories under /SAMBA/SMB207. The previous version of Samba/iX 1.9.16p9 still exists inside the SAMBA account in HFS directories under /SAMBA/PUB. You can only run one version of Samba/iX server at one time.

If you choose to run the new version of Samba/iX 2.0.7, please use the following procedures to start the Samba/iX 2.0.7 server.

Starting smbd and nmbd Listener Jobs

Logon as manager.sys

Use the following commands to create symbolic link to make /SAMBA/SMB207 link to /usr/local/samba

          
  :purgelink /usr/local/samba
  :newlink  /usr/local/samba, /SAMBA/SMB207

Customize the smb.conf, printcap and user.map files to suit your Samba/iX environment. The smb.conf, printcap and user.map files should reside in the /SAMBA/SMB207/lib directory.

Use the jobs supplied as JSMB207.SAMBA.SYS and JNMB207.SAMBA.SYS and stream them. By streaming these two jobs, it starts your SMBD listener and NMBD server.

Use SHOWJOB to see if the job is still alive; it can look as follows:


  JOBNUM         STATE    JIN     JLIST    JOB NAME
  #j50           EXEC     10S     LP       NMBMON,MGR.SAMBA
  #j51           EXEC     10S     LP       SMBMON,MGR.SAMBA

Starting Samba/iX Under the INETD Control

If you choose to run SMBD and NMBD processes under control of INETD, you should use the following procedures to start the Samba/iX server:

Logon as managers.sys.

Use the following commands to create the symbolic link to make /SAMBA/SMB207 link to /usr/local/samba.
```
  :purgelink /usr/local/samba
  :newlink /usr/local/samba, /SAMBA/SMB207
```

Windows Registry Hacks to Supported Unencrypted Passwords

Connecting to SMB servers (such as Samba) with unencrypted password fails after upgrading to Windows NT 4.0 service pack 3 (and above). Currently encrypted passwords are not supported in Samba/iX 2.0.7. Please follow the procedure given below to work around this limitation:

Cause:

The SMB redirector in Windows NT 4.0 (service pack 3 and above) handles unencrypted passwords differently than previous version of Windows NT. Beginning with this version, the SMB redirector will not send an unencrypted password unless you add a registry entry to enable them.

Resolution:

To enable unencrypted (plain text) passwords modify the registry in this way.

WARNING! Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft does not guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

Run Registry Editor (REGEDT32.EXE).

From the HKEY_LOCAL_MACHINE subtree, go to the following key: \system\currentcontrolset\services\rdr\parameters

From the Edit menu, select Add Value.

Add the following:

          
  Value Name: EnablePlainTextPassword
  Data Type: REG_DWORD
  Data: 1

Choose OK and quit Registry Editor.

Shutdown and restart Windows NT.
