This moves it right into the passdb subsystem, where we can do this in just one (or 2) places. Due to the fact that this code can be in a tight loop, I've had to make 'guest account' a 'const' paramater, where % macros cannot be used. In any case, if the 'guest account' varies, we are in for some nasty cases in the other code, so it's useful anyway. Andrew Bartlett |

While this article is specific to the recent Nimda worm, the information can be applied to preventing the spread of many Win32 viruses. Thanks to the Samba Users Group of Japan (SUGJ) for this article. =============================================================================== Steps againt Nimba Worm for Samba Author: HASEGAWA Yosuke Translator: TAKAHASHI Motonobu <monyo@samba.gr.jp> The information in this article applies to Samba 2.0.x Samba 2.2.x Windows 95/98/Me/NT/2000 SYMPTOMS This article has described the measure against Nimba Worm for Samba server. DESCRIPTION Nimba Worm is infected through the shared disk on a network besides Microsoft IIS, Internet Explorer and mailer of Outlook series. At this time, the worm copies itself by the name *.nws and *.eml on the shared disk, moreover, by the name of Riched20.dll in the folder where *.doc file is included. To prevent infection through the shared disk offered by Samba, set up as follows: ----- [global] ... # This can break Administration installations of Office2k. # in that case, don't veto the riched20.dll veto files = /*.eml/*.nws/riched20.dll/ ----- Setting up "veto files" parameter, the matched files on the Samba server are completely hidden from the clients and become impossible to access them at all. In addition to it, the following setting are also pointed out by the samba-jp:09448 thread: when the "(Jreadme.txt.{3050F4D8-98B5-11CF-BB82-00AA00BDCE0B}"(B file exists on a Samba server, it is visible only with "readme.txt" and a dangerous code may be performed when this file is double-clicked. Setting the following, ----- veto files = /*.{*}/ ----- no files having CLSID in its file extension can be accessed from any clients. This technical article is created based on the discussion of samba-jp:09448 and samba-jp:10900 threads.
