Hi all We are implementing samba-ldap to act as an nt pdc and are seeing performance problems. We have a 1ghz, 3gb Ram, 36gb box that is running samba-2.2.5 and openldap-2.0.23 under redhat 7.3 with kernel 2.4.18-3. Clients are all Win2k SP3. All the ldap requests are to the localhost interface. The box is acting as the PDC for the domain, and also sharing diskspace and printers. When we get

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

Does "bwlimit" option really work on rsync locally? We have one type of harddisk and want to slow down rsync I/O on disk because I don't want the disk head gets too hot. While I'm trying to use --bwlimit option, it looks the rsync speed was slowed down, but iostat is not improved at all. In both case the block written speed is increased by the same amount. How could I really

Well, you are the second person who has complained about the performance of OCFS with the PERC controller. Best option would be to contact DELL. We are in contact with them... as in, they inform us of any issues they have with linux/ocfs on their hardware. As we do not have this particular hardware inhouse, all we can only speculate as to what the issue is. Things to look for ==> output

Hello, We are planning to moving most of our servers to ESX but before buying our SAN, we want to do some I/O stats to see if iSCSI is enough or if we have to go with FC. So I found a plugin for Nagios that can log I/O stats with iostat. So far it's fine with single disk/one partition servers, but on our Oracle Database 10g server, we have two drives in RAID 1 (/dev/sda) and 4 other

Hi Folks, I've inherited an old RH7 system that I'd like to upgrade to CentOS6.1 by means of wiping it clean and doing a fresh install. However, the system has a software raid setup that I wish to keep untouched as it has data on that I must keep. Or at the very least, TRY to keep. If all else fails, then so be it and I'll just recreate the thing. I do plan on backing up

Hello, I have just get started using pxelinux, and encountered a problem. The document says the simple menu system supports serial console, and it works on syslinux 0.2x, but it doesn't seem to work in 0.3x and 0.4x.

I just had a problem that had me stumped for an hour. All of a sudden all of my view specs were failing, and I couldn''t get good troubleshooting information from the rspec output. The output from running `rake specs` was a bunch of HTML from app/views/exceptions/internal_server_error.html.erb, but there wasn''t enough info there to diagnose my problem. It just said

Hi all, Can anyone suggest some methods and tools to help troubleshoot a problem with SID's? I am using Samba 3.0.2a on RH9 joined to a W2K ADS "security = ads". I am trying to set NT ACL permissions on my shares, but after they are set and the Everyone group is removed, the users cannot connect to the share. With logging turned up, I can see access checks, but the user sid does not

How can I debug SIP DTMF? If I do 'sip set debug peer xyz' I see no messages related to DTMF... or if I just do a global SIP debug for that matter.... I am using RFC DTMF but it's not being passed to the PSTN and I need to debug this further. I've tried to increase the verbosity and the debug ('set debug n') and that didn't help either. I assume this is because even

Hi, I'm trying to print to a printer that is connected to an NT 4 Server. The problem is, that nothing comes out of the printer, and I get no error messages, neither on the Linux nor the NT box. The printer queue on NT is empty. Where can I look in order to find out what the problem is? Here is a session with smbclient: dsadmin@linux:~ > smbclient //pc02/hp5pnt added interface

Hi! I am on Ubuntu 20.04 with the vendor provided Samba 4.15.13 packages. My smb.conf is at the end of the email. I have Gnome Tracker set up and working (from the command prompt on the server, tracker search keyword, is working) as per https://wiki.samba.org/index.php/Spotlight_with_Gnome_Tracker_Backend However, from the macOS workstation side, Spotlight still does not appear to be working

Hi, I was wondering if there was a logging category for which I can increase the verbosity for spotlight? I am trying to set up Samba 4 with Gnome Tracker as the backend, and I followed the Samba wiki ( https://wiki.samba.org/index.php/Spotlight_with_Gnome_Tracker_Backend ). The tracker backend is working, but spotlight itself still isn't working on workstations (trying to search on a shared
