SAMBA migration issue

[Revnon]

Hi

1)Are you running the latest version of OS plus Samba on RHEL 5?
Yup. RHEL 5.5 and latest Samba

2) You do have duplex and speed setting on your NIC card(s) set up properly?
May i know how do i verify on this?
Accessing the New Server thru FTP, Rysnc, WEBMIN is fast it seems.

3)Does the 'testparm' SAMBA utility report anything weird with your
smbd.conf file?
No Errors.


4)In terms of the tdb files, have you backed them up during the file
migration? (usually under
/var/lib/samba). Usually I do (see SAMBA HOW TO 41. Managing TDB files. I am
not sure how tdb file lookup could affect performance at large.
Hmm, didn't move these files, as well as, secrets.tdb over.
Just wondering if now i move these files from OLD server to the NEW server,
and restart SMB, will it helps?


With Regards,
re\/non
