Hi Experts , Wanted to Join Samba 4.13 to Win2K as ADC on Samba box of 4vcpu/16 GB RAm . It failed while "committing SAM database" , which took few hours . Need Advice for * How can we rejoin , what are steps needs to perform at Win2K side for cleanup ? * Why "Committing SAM Database " taking so much of time for 2K Users and 3K Computers ?...

Hi, The measurements were created under the following conditions : ? operating system : Red Hat Enterprise Linux Server release 6.6 (Santiago) kernel in version 2.6.32-504.el6.x86_64 ? virtual server (VMware) with an Intel(R) Xeon(R) 4vCPU E5649 x 2,526 GHz (2 cores per virtual socket) and 4 GB RAM ? 7,200 RPM SATA 1TB (FC SAN IBM System Storage N3400) ? all file systems had been formated in ext4 ? Dovecot v.2.0.9 ? imaptest v.1.0.0 ? LDAP 389 Directory Server v.1.2.2 ? free pagecache, dentries and inodes: echo 3 > /proc/sys/vm/dr...

Hi, I would need some suggestion for a dovecot based mail infrastructure. Actually, only one server (with dovecot sendmail amavis spamassassin clamav etc etc) is no longer enouth, so I thought I would put on a more complex infrastructure on different servers. But I do not know a few things. I was thinking about partitioning users on 3-4 servers with dovecot (imap / pop3) and dovecot-lda (no

Hi All, I am sure this has been answered somewhere in the list in the past, but I can''t find it. I was wondering if the linux guest netfront driver has GRO support in it. tcpdump shows packets coming in with 1500 bytes, although the eth0 in dom0 and the vif corresponding to the linux guest in dom0 is showing that they receive large packet: In dom0: eth0 Link encap:Ethernet HWaddr
