Okay, so I've just put the sernet repo file in my yum.repos.d directory and a yum update will elevate my samba server to the latest version. Is there any pitfall that is out there that I can avoid before yum updating. Centos 5.3 samba3-3.0.34-37 & related packages openldap-2.3.43-3.el5 & related packages I still have my samba3-3.0.34 packages squirreled away so I can force downgrade

Hi all, i have a new setup where the htdocs directory for the webserver is located on a nfs share. Client has cachefilesd configured. Compared to the old setup (htdocs directory is on the local disk) the performance is not so gratifying. The disk is "faster" compared to the ethernet link but the cache should at least compensate this a bit. Do they exist more pitfalls for such

Let''s say you want to validate that an attribute contains only 2-10 lowercase characters, e.g. with validates_format_of. The appropriate regex is obviously /^[a-z]{2,10}$/, right? Wrong! Try it with "abc\nANYTHING YOU LIKE" - this is perfectly valid. On the second look the reason is clear: ^ matches the start of a line, $ matches the end of a line. So as long as one line in

I have recently run across this problem and would like to warn people about it. I had an already established domain running under Samba 2.2.8. I then upgraded to 3.0. I removed the 'domain admin users = root' line from my smb.conf because certain tools complained about it being there. After the upgrade, I followed the Samba 3 HOWTO docs on samba.org. I created my domadm, domguests, and

One issue I've been looking at with regard to using LLVM as a compiler backend is distribution of programs, particularly on Linux where different distributions have different binary package formats and it is usual to ship programs as source rather than binary; specifically, I'm looking at the general case where the end user may not have (the correct version of) LLVM installed, so the

Hello Russell, Major pitfall #1: LLVM-GCC does certain optimizations even if all of the optimizations are turned off. These include endian-specific optimizations so to use LLVM as a cross-architecture bitcode, you'll need to wait until Clang supports C++ fully or just stick to C programs for now. I've been looking forward to the day that LLVM can be used for cross-architecture

Hi, I'm going to have a go with realtime mysql. Just wondering, most examples i came across while googling, was with 1.6 systems. So any drastic changes with 1.8.3, table-layout? other pitfalls? hw

Hello, we are running Dovecot (2.2.13-12~deb8u1) on Debian stable. Configured with Mailbox++, IMAP, POP3, LMTPD, Managesieved, ACL. Mailboxes are on local 1.2TB RAID, it's about 5310 accounts. We are slowly getting out of space and we are considering to move Mailboxes onto Netapp disk array with two independent network connections. Are there some pitfalls? Not sure we should use NTP or

Hi folks, As a breather from the "thread-now-wider-than-my-headers-window-in-thunderbird" conversation re: mixing repos, I have a question regarding a machine I'm about to put online. :) I run a web hosting company and my secondary (primary to the world) DNS box died from a massive rootkit/hack last night. It was running an old Slackware 9.1 installation and I will be completely

I'm looking to acquire a few new core switches for our network which would be a major upgrade from the cheap unmanaged things we currently have. Basically, just users, servers, and other simple network devices will be plugged into them but I'd like to start doing some testing with iSCSI for various non-production reasons. I have no allegiance to a particular vendor although I do have a

When I say busybox it''s actually VMware ESX server which seems to use busybox (which I guess is the case a number of other software appliances) . Reason for wanting to install puppet is to run the cli tools to create nightly vmware snapshots. I''m happy to give it a go (and add the docs to the wiki) but I''m not too sure at this stage how big a task this might be and what,

I don't think I quite understand this... suppose for example you're trying to use an LLVM-based toolchain running on an x86 PC to write code for a device that uses an ARM processor in big endian mode, so you tell the LLVM code generator "generate code for ARM, big endian"... are you saying the optimizer will actually assume the target device is little endian because the

Hi, after some off-ML discussions to and some reconsiderations, we might do the "big jump" from our current 1.2.17 to the atrpms 2.2. From googling and reading the dovecot upgrade wiki I don't see any (big) pitfalls. Basically we use the default config options, mbox, pop3s/imaps on RH EL 5. So "just" run the upgrade-config script, fingers crossed and thats it? Ii it

Hi all, I have plan to replace my Centos5.7 VM with newer version. The VM works as our network gateway. I want to ask from your experience, will it be a bad decision? My concern is that since the Mac Address of the gateway will change, will it disrupt the network? How fast the Switches can recognize the new mac? Any other pitfall? Thanks Fajar.

Good day Guys Just wanted to pick the communities brain and experience(s) for a second. At $CORP where I work. My team has inherited a single server mail solution. We need to look to building a standby / replicated solution. One of the things we were looking at is https://wiki.dovecot.org/Replication We have in excess of +/- 500 mail boxes and using just under 1TB of disk space. That is a

Hi, I am in trying to get a new Linux Cluster. I am thinking about putting R on it. Does anyone have any experience with running R on a distributed Linux Cluster? Or does R support a cluster environment at all. Any pitfall I should really watch out for? Thanks in advance Apollo

Has anyone been able to get asterisk 1.6 running under Xen or Amazon EC2? If yes, can you share your experience please? Is it usable in a production environment? How is the sound quality? Am I likely to suffer from latency issues if the extensions are not located in the US? Any pitfall that I should be aware of? Cheers -- Aryan Ameri

Hi all, I haven't found anything in Google about this. I'm creating a firewall router with Centos with few virtual IP using iptables. May I ask for your experience? Is there any pitfall or bad side of using virtual IP for this purpose? I'm using few virtual IP to accommodate few subnets that go through this firewall/router. Thank you. Fajar.

I just ordered a new machine that's destined to become a Centos 6 application server for a publishing company, and decided to get one with a 40GB SSD as well as a standard hard drive. I'm thinking that I can put most of the operating system on that drive and have the home directories and whatnot on the regular hard drive. Are there any pitfalls lying in wait for an unwary person like me

I have built a new server (FreeBSD-12) running dovecot-2.3.4. My old server (FreeBSD-9.3) is running dovecot-2.3.4 as well. The configurations are 1:1 identical. The are about 250 users on this server, all virtual. They are mostly POP3 users, but they do "leave a copy of message on the server" for set various number of days. Now, to migrate the mail data, can I simply rsync the mail
