Re: Trouble with mount.cifs while smbclient works (Ubuntu 12.04)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Don't want to forget is to open a bug report (at bugzilla.samba.org)
if you haven't already created one - even if tricky to fix safely, I
don't want to lose track of this issue if we can find a way to safely
handle this case.   There is a lot going on in development of cifs.ko
with smb2 enablement and the introduction of "SMB 3" (and also some
dramatic performance improvements that went in over the last four
releases).
