similar to: quite dramatic and sudden problem...

I mounted a samba volume on XP. XP and Ubuntu are connected over 100Mbps ethernet (router). I am writing a 4GB file from XP to Ubuntu and the transfer is extremely slow : only around 1-1.5 MB/s. This is not a network or disk issue since at the same time this transfer is gonig on, I can scp the same file from XP to Ubuntu at 3-4 times faster (around 6MB/s). What could be wrong? Even for this

hi everyone, i'm new to samba, i did an install and configure of samba 3.0.33 on red hat 5, security is = ADS. All seems quite good but... some users are not allowed to connect ("Username.... is invalid on this system" is in log files). done some debugging with wbinfo: #wbinfo -u | grep <username OK> <username OK> #wbinfo -i <username OK> blabla correct user

Hello, I always wanted to ask: do you need to reboot after updating packages like kernel, glibc, postgresql? Or do you need to restart the postgresql service after updating it with yum?

Hi everyone, I am currently trying to set-up a samba server in my network in order to replace the existing windows samba server. It's been now two weeks that I am struggling with a vicious problem, and I cannot see any issue right now. Before I loose all my hairs, I am sharing with you this problem : hopefully, someone will have a tip for me. The software involved : Server Linux

Hi, For the last day or two I having been trying to get Valgrind/Callgrind 3.6.1 to work on Centos Linux 5.5 using a simple Fibonacci C++ program(shown below). After compiling the program using g++ -g -o MatchUpAccurate MatchUpAccurate.cpp, we run: /home/frankc/DQTTest/valgrind-3.6.1/coregrind/valgrind --tool=callgrind --dump-instr=yes --simulate-cache=yes --collect-jumps=yes

After moving from Redhat AS4 to RHEL 5.5 we started noticing these error messages in the messages log. Upgrade procedure was to build new machine with updated OS, install new samba, duplicate existing ldap server connections, and then shutdown the old box and put new one in place. Messages were not seen on AS4 box and smb.conf file is identical on new box. I am wondering if there was a change

Issue: unix fifo (named pipe) does not appear in share, attempts to read the pipe result in "Access Denied" >From an XP laptop, I can open and access my samba share normally. I can read all files and subdirectories in the share, but a fifo I need to read does not appear at all. I have made the fifo mode 777 (world readable, writeable, executeable) and tried other things like

There are options that can help a little bit with the ls/find. Still, many devs will need to know your settings, so the volume's info is very important. Try the 'noatime,nodiratime' (if ZFS supports them). Also, as this is a new cluster you can try to setup XFS and verify if the issue is the same. RedHat provide an XFS options' calculator but it requires aby kind of subscription

Hi everyone, I'm trying to use samba in a small video post production house but we are not getting the performance we expected. Our setup: - CenOS 5.6 x86-64 - samba.x86_64 (3.0.33-3.29.el5_6.2 and 3.6.0rc1) - Intel based server (One 4 core Xeon E5620 @ 2.40GHz, 8 GB RAM) - 4 Intel Gigagit ethernet NIC ports with 802.3ad bonding connected to a switch configured tu use 802.3ad - 8 2TB 7.2

Hi. I've got some samba servers (3.0.33-3.29.el5_6.2, on redhat 5) that join a windows 2003 AD. When mounting the volume from a windows workstation, if I use \\ip.address.here it fails saying "The trust relationship between this workstation and the primary domain failed'" If I mount with \\fully.qualified.name it works just fine. Forward and reverse DNS match, and

Greetings to all. It's my first post to the list. We just completed a migration from qpopper to dovecot for our IMAP and POP3 services. We have a rather large mail environment (we are the biggest provider in Greece). So, here are the details: - Keep getting errors like these in our production environment Jul 22 00:18:21 pop01 dovecot: master: Error: service(pop3): child 4078 killed with

Hi all, I'm using Wine for a MotionCapturing Application (Qualisys). Although it's a quite recent application, it works well (I tried only data processing so far), but when I try to save a dataset (~180MB), it takes about 20 Minutes (!!) on my Computer. When I use it under VirtualBox (it does not run nicely there because of OpenGL), saving takes about 20 seconds. When I look at

Hi all, I have been a Wine user since about 2002 and have even contributed a few simple patches, but this is my first time on the forum. Anyway, I just wanted to make it known that wine 1.3.20 provides a dramatic increase in performance. Scrolling in the iTunes Music store no longer reminds me of pouring molasses (finally) and Photoshop Elements 5 is usable. Does anyone know what the magic was and

True, I just hoped you or one of the other devs might have some insight on reclaim behaviour that would provide a clue. I guess I'll try a

Dear R users/developers, simple comparison of code execution time of R 2.7.1 and R 2.7.2 shows a dramatic slowdown of the newer version. Rprof() identifies .Call function as a main cause (see the code below). What happened with R 2.7.2?

Hi all, This is not really a libvirt issue but I'm hoping some of the smart folks here will know more about this problem... We have noticed when running some HPC applications on our OpenStack (libvirt+KVM) cloud that the same application occasionally performs much worse (4-5x slowdown) than normal. We can reproduce this quite easily by filling pagecache (i.e. dd-ing a single large file to
