After today's samba update, Centos 3 boxes can not use samba to communicate with each other, although Windows and the Centos 3 boxes see each other correctly as do RHEL5 and the Centos3 boxes. The du command works well, but ls, cp, cat ,etc produces the error: PANIC: push_ascii - dest_len == -1 in the server log and smb_trans2_request: result=-5, setting invalid in the client. A similar (but more serious) set of problems was reported in Ubuntu early this morning after their update. Is any one else experiencing this problem with samba and Centos 3 after the update? regards, benm

Or even better at bugzilla.redhat.com and provide us with the bug number there? Thanks, Ralph -------------- next part -------------- A non-text attachment was scrubbed...

The duUpon further investigation, samba can only no longer use wildcards of any type or do things like 'ls' . Doing ls /mnt/SHARE/<complete file name> works fine whereas ls /mnt/SHARE/<partial>* gives an invalid result. I wonder if there is still is a compilation option (there was a few years ago) to enable/disable wildcards which is either turned off or has been disabled? If one knows the complete file name on a Centos 3 share then one has no problem. Windows boxes (and Linux boxes other than Centos 3) work fine and that is the way most admins use samba so this is hardly a crisis. ( Unlike the Ubuntu people who report that nmbd is segfaulting on their boxes and apparently have a different problem). regards, benm

Near identical wildcard problem reported 11-16-07 after security update in Gentoo. See: http://forums.gentoo.org/viewtopic-p-4509521.html?sid=e417b093d116b24b4bb819bcbd949473 FWIW, Gentoo bug number is 199450. Unlike the ubuntu version of this problem, neither the RHEL3 nor the Gentoo bugs segfault nmbd. The updated RHEL5 CLIENT does not exhibit the problem. The RHEL3 CLIENTS exhibit the problem after Centos3 or RHEL5 samba SERVER updates. All this is reversible by installing the old rpms respectively. The Gentoo issue is similarly reversible. This looks like this could be a null pointer dereference issue caused by the samba security patch. Bug reports probably need to be upgraded a notch from low priority since a lot of people apparently have mixed linux-win networks and use linux-to-linux samba transfers. regards, benm --Alt-Boundary-3379.18435061 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head> <title></title> <meta http-equiv="content-type" content="text/html;charset=utf-8"/> <meta http-equiv="Content-Style-Type" content="text/css"/> </head> <body> <div align="left"> <font face="Arial" color="#7f0000" size="2"> <span style=" font-size:10pt">  > Can you file a bug at bugs.centos.org?
