• How does enterprise failover, such as with google.com, actually work?

  - by Alex Regan

  We have a few fedora systems that are configured for web, FTP, and email services. We'd like to mirror these services, so that we can provide near 100% reliability for our users. I'm a fairly experienced Linux administrator, but don't have much experience with redundant systems. What is the best way to do this? How does google and amazon do it? Google.com resolves to multiple IP addresses, but if my local desktop caches one of the IPs that are unreachable, I'm going to get a failed connection message. How do they prevent that from happening? If one of their servers goes down, how is it automatically redirected to another system, without the end-user ever knowing it? I understand there are failover devices, but they're only for failing over the system itself, not a complete network. Let's say we have the worst-case scenario, such as my primary system becomes inaccessible. What are the fundamental components that are used on Linux systems to provide this capability? I'm looking for concepts, or approaches, not answers like "check out openstack". What are the actual pieces that make up the solution? What has to be done to implement this capability? Hopefully my question is clear. I'd like to know what the pieces are that make up a failover system and what approach is taken by successful organizations that implement it. Thanks again, Alex

• is it worth to use load balancer on web server/website

  - by user427969

  I have a website and a while ago, the web server of the company hosting my website was down for about a day. I consulted the company for a solution on how i can stop this from happening in future and they suggested to have a second machine and which will be connected to my current website/web server by a "load balancer" (at an additional huge cost!!!). The second machine will be replicate of the first one and so if i goes down, the other will always be running. ---- Explanation ----- My hosting company suggested that it will be a good idea to have a second machine running at the same time and both the machines will be connected by a load balancer which reduces the rist of a downtime. The second machine will be a mirror of the first and any changes to first must be replicated in the second. I don't mind spending money if it really saves my website from going down. I want to know is it worth having this "load balancer" for my purpose? My website is a 24/7 service. I cannot afford an outage of 24 hours/1 hour. I don't mind using this "load balancer" as far as it is really worth. I am not sure if its just a marketing trick of my hosting company or really a "best" solution Thanks for help. Regards

• How does one change the UUID of a Volume on Mac OSX 10.6?

  - by Emmel

  Does anyone know how to change the UUID of a Volume? The background for this question is that I have a duplicate UUID issue: I have /Volumes/OldMacHD with a UUID of XYZ. I have /Volumes/Mirror1 with a UUID of XYZ (same UUID! I bet that's because OldMacHD USED to be part of this mirror). I got these UUIDs via 'diskutil info /dev/thatdisknumber | grep UUID'. I'd like to change the UUID of 'Mirror1'. I discovered by chance the 'hfs.util' utility, since these are HFS volumes after all. The man page for hfs.util says that if you issue the -s flag, this changes the UUID. However, if you type hfs.util all by itself, it doesn't show you the -s option at all, just every option besides that! Grr. I tried it anyway: sudo /System/Library/Filesystems/hfs.fs/hfs.util -s /dev/disk4 (the raid volume). Nothing happens. No error message, no success message. UUID exactly the same. I tried it while the volume was unmounted. Any ideas?

• Using mixed disks and OpenFiler to create RAID storage

  - by Cylindric

  I need to improve my home storage to add some resilience. I currently have four disks, as follows: D0: 500Gb (System, Boot) D1: 1Tb D2: 500Gb D3: 250Gb There's a mix of partitions on there, so it's not JBOD, but data is pretty spread out and not redundant. As this is my primary PC and I don't want to give up the entire OS to storage, my plan is to use OpenFiler in a VM to create a virtual SAN. I will also use Windows Software RAID to mirror the OS. Partitions will be created as follows: D0 P1: 100Mb: System-Reserved Boot D0 P2: 50Gb: Virtual Machine VMDKs for OS D0 P3: 350Gb: Data D1 P1: 100Mb: System-Reserved Boot D1 P2: 50Gb: Virtual Machine VMDKs for OS D1 P3: 800Gb: Data D2 P1: 450Gb: Data D3 P1: 200Gb: Data This will result in: Mirrored boot partition Mirrored Operating system Mirrored Virtual machine O/S disks Four partitions for data In the four data partitions I will create several large VMDK files, which I will "mount" into OpenFiler as block-storage devices, combined into three RAID arrays (due to the differing disk sizes) In effect, I'll end up with the following usable partitions SYSTEM 100Mb the small boot partition created by the Windows 7 installer (RAID-1) HOST 50Gb the Windows 7 partition (RAID-1) GUESTS 50Gb Virtual machine Guest VMDK's (RAID-1) VG1 900Gb Volume group consisting of a RAID-5 and two RAID-1 VG2 300Gb Volume group consisting of a single disk On VG1 I can dynamically assign storage for my media, photographs, documents, whatever, and it will be safe. On VG2 I can dynamically assign storage for my data that is not critical, and easily recoverable, as it is not safe. Are there any particular 'gotchas' when implementing a virtual OpenFiler like this? Is the recovery process for a failing disk going to be very problematic? Thanks.

• Windows Vista Nested Desktop Folders Problem

  - by Samuel Walker

  I have no idea how, nor when this happened, and it's started to really quite annoy me. When navigating through Explorer, by clicking on Icons I have C:\Users\Samuel\Desktop (Icon is the blue special Desktop icon), which contains the items I see on my Desktop. I then have the following folder: C:\Users\Samuel\Desktop (Icon is the standard yellow folder icon), which contains many program shortcuts, and is completely seperate from the other C:\Users\Samuel\Desktop Then in the Yellow Icon Desktop I have the sub-folder Desktop with the blue icon that is a direct mirror of the blue C:\Users\Samuel\Desktop folder (as in a new folder / file shows up in both). In explorer when I directly type C:\Users\Samuel\Desktop I am taken to the Yellow folder version. If I go to C:\Users\Samuel\Desktop\Desktop I am taken to the Blue folder version. Finally, from cmd cd'ing to C:\Users\Samuel\Desktop takes me to the Yellow folder version whilst C:\Users\Samuel\Desktop\Desktop takes me to the blue folder version. How on earth can I get rid of the yellow folder version leaving the blue C:\Users\Samuel\Desktop. I can't delete either as it says they're in use. UPDATE: Ok, so it looks like doing a dir from cmd lists only one Desktop folder - the Yellow one. In addition, it looks like I can't delete either of them (given that they both contain my 'Desktop'

• Bridged network on OS X only gets UDP broadcast traffic

  - by a paid nerd

  I've created a bridged network Mac OS X 10.8.5 using ifconfig and TUNTAP for OS X to bridge my wireless connection, en0, with a virtual interface, tap0, which I can use for guest VMs: $ sudo sysctl -w net.inet.ip.forwarding=1 $ sudo sysctl -w net.link.ether.inet.proxyall=1 $ sudo sysctl -w net.inet.ip.fw.enable=1 $ sudo ifconfig bridge0 create $ sudo ifconfig bridge0 addm en0 addm tap0 $ sudo ifconfig bridge0 up $ ifconfig en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 28:cf:xx:xx:xx:xx inet6 xxxx::xxxx:xxxx:xxxx:xxxx%en0 prefixlen 64 scopeid 0x4 inet 192.168.100.64 netmask 0xffffff00 broadcast 192.168.100.1 media: autoselect status: active bridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether ac:de:xx:xx:xx:xx Configuration: priority 0 hellotime 0 fwddelay 0 maxage 0 ipfilter disabled flags 0x2 member: en0 flags=3<LEARNING,DISCOVER> port 4 priority 0 path cost 0 member: tap0 flags=3<LEARNING,DISCOVER> port 8 priority 0 path cost 0 tap0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 ether ca:3d:xx:xx:xx:xx open (pid 88244) However, if I tcpdump -i tap0, I only see broadcast traffic. Shouldn't I see a mirror of everything on en0? (192.168.100.33, the host doing the broadcasting, is another unrelate, noisy server on my LAN.) (I asked a similar question here and will probably close it.)

• Backup and Archive Strategy Question

  - by OneNerd

  I am having trouble finding a backup strategy for our code assets that 'just works' without any manual intervention. Goal is to have an off-site backup (a synchronized one) so that when we check-in files, create builds, etc. to the network drive, the entire folder structure is automatically synchronized and backed-up (in real time, or 1x per day) at some off-site location so if our office blows up, we don't lose all of our data. I have looked into some online backup services, but have not yet had any success. Some are quirky/buggy, others limit file size and/or kinds of files (which doesn't work well for developer files). Everything gets checked in and saved to a single server (on a Raid Mirror), so we just need to have a folder on that server backed up/synchronized to some off-site location. So my question is this. What are you using for your off-site backup strategy. What software, system, or service? Is there a be-all/end-all system of backing up your code assets that I just haven't found yet? Thanks

• Rsync: General file/folder synchronization

  - by Rey Leonard Amorato

  I have a file server, which is in-charge of pulling a folder tree from multiple workstations on a daily basis. My current method for this is by using rsync, (which works pretty well provided directory names and/or files remain the same) however, when files are renamed or moved about within subdir1, rsync will copy them over to the server, creating duplicates. I have to manually find and delete extraneous files/folders that had been left on the server during previous syncs. Note that I cannot use rsync's --delete flag because any sync from a workstation will then mirror that particular folder tree, instead of merging them to the server. Visual diagram: Server: Workstation1 Workstation2 Workstation(n) Folder* Folder* Folder* Folder* -subdir1 -subdir1 -subdir1 -subdir(n) -file1 -file1 -file2 -file(n) -file2 -file(n) Is there a simple script (preferably in bash, nothing fancy) that can accomplish the deletion of the extraneous files/folders in the event a file is renamed or moved to a different subdir? Is there a different program, much like rsync that can accomplish this task autonomously and in a much simpler manner? I have looked at unison, but I did not like the fact that it keeps a local database for the syncing info. Any tips at all as to how I am supposed to tackle this? Thank you in advanced for your help. EDIT: I have tried unison just recently and I can safely say it is out of the question now. unison is a bi-directional synchronization tool and from my testing, it mirrors the files existing on the server to all workstations. - This is unwanted. preferably, i would want files/folders to stay within their respective workstations and just merge to the server. AKA uni-directional sync; but with renames/moves propagated to the server. I might have to look into Git/Mercurial/Bazaar as mentioned by kyle, but still unsure if they are fit for the job.

• sql 2008 disk layout on a budget this is for database mirroring

  - by user22215

  Guys I'm rolling out a SQL database server that will be used to back Sharepoint 2007. Right now I need some advice on my disk layout. I have two Dell servers that are configured a little differently in terms of storage. The principle server will be using a combination of local storage and san storage. I have to work with what I have the organization is currently all allocated on san storage it was like pulling teeth to even get what I have to work with now. My disk setup on the principle is as follows: raid 1 for OS raid 10 for logs raid 10 fiber on san for high IO databases raid 10 sata on san for content databases My question in regards to the principle server is where should I place the temp db? I thought about placing it on the fiber raid 10 which will be hosting my high IO Sharepoint SSP databases my only other choice is to move it to the raid 1 os partition which I’m sure you guys will be against. Now let’s talk about the mirror server it is not connected to the san it is all local 6 15k SAS drives. Now my question is the same do I put tempdb on the os partition or do I leave the os partition and use a single raid 10 for everything? Any help you can provide is much appreciated.

• Software mirroring (RAID1) versus "Fake Raid" for new Windows 7 install

  - by kquinn

  I've just ordered two new hard drives for my main desktop and a copy of Windows 7 Professional 64-bit. I'd like to do a clean install of Win7 onto the new drives (leaving my old XP Pro boot partition around for a while in case something goes disastrously wrong, etc.). I want to have them set up in mirrored (RAID-1) mode. My understanding is that Win7 Pro can do software mirroring, but can I set this up directly at install time? If so, how? Note that I'd like the disk to be split into three partitions (OS/Apps&Data/Bulk data), all of which should be mirrored. Would it be better (more reliable or faster) to use my motherboard's hardware RAID support? My motherboard is an older nVidia nForce 680i SLI, which is not the most stable of motherboards, and I'm not sure how trustworthy its RAID1 configuration might be (or if Win7 could even detect and install onto a hardware-mirrored volume). Also, the performance characteristics of RAID1 are rather different than RAID0 or RAID5, and I'm wondering if Win7's software mirroring might actually be faster than hardware RAID1 (for example, I'm more of a Unix admin when I have to wear the sysadmin hat, and I've had great success deploying ZFS; most hardware RAID1 implementations have to read both disks and compare results to look for data errors, but ZFS can read from only one disk in the mirror and just use the built-in checksum, meaning it can have up to 2x the number of reads in-flight, as long as there's no data corruption). Edit: Okay, my question about whether Windows 7 can do software mirroring has been answered, and it can. I'm still unsure whether Windows software RAID or my motherboard's hardware "fake RAID" function is a better choice, though. Remember, I'm only interested in mirroring -- not the more complicated striping or parity operations that generally show the poor performance of crappy motherboard RAID solutions.

• Windows XP corrupts registry every several hours

  - by Ilya Kazakevich

  There is a Dell XPS 400 with Windows Media Center installer. It is installed on RAID (Intel Matrix Storage) which is built-in chipset south bridge. Raid has two 150 Gb WDC drivers connected as mirror. All drivers and updates are installed( sp3 and so on). A week ago PC changed its video mode to 256 colors (like VESA mode) and after several moments I got BSOD: c000021a: 0xc0000005 Doctor watson did not create dump although it is installed as default debugger. After reboot it said that config file is missing or corrupted. So, I boot to recovery console and found that registry file (config) is so small. I've replaced it with one from recovery point and windows booted sucessfully. But after about 3 hrs -- it has crashed again in the same wat! I look in event viewer: is said that Explorer.exe failed to open \global??\DLIAFS. I look in winobj, and found that it is a device. I made "deny from everyone" for this device ACL, and after several hours my windows crashed. I restored registry, boot again and there was no error about DLIAFS. I did full chkdsk and it did not found anything bad. But I found event about error paging to \Harddrive1\D. I do not have pagefile there, but I thought I should check my disk again. Unfortunatelly I cannt use smart tools for RAID, but I downloaded latest software from Intel (it can do the same things like RAID bios can but from windows). It verified my disks, found some errors, fix them, than I rebooted. And it crashed again. I am lost. What (except kernel debugging) could be done here? Thanks

• File corruption after copying files in Windows 7 64 bit using two methods

  - by DustByte

  I have 5000 pictures and other files in a directory taking up 35 GB. I want to duplicate this directory. Method 1: I do a simple copy and paste of the directory in explorer. I have the habit of checking the checksums after copying important files. In this case I noticed that around 2000 files failed the MD5 test. At a closer inspection of a randomly chosen JPEG with different checksums it turns out that some XMP metadata had changed. In particular, the tag <MicrosoftPhoto:DateAcquired> had changed the date from 2009 to today (possibly around the time I was copying the files). I have no idea what triggered this XMP data to be changed and exactly when it was changed and why for these particular files, but at least it seems to explain the checksum discrepancy. Method 2: As I want the exact files to be duplicated, I tried the program FreeFileSync to mirror the directory, hoping no XMP metadata would mysteriously change. A checksum test in addition to a thorough file comparison test in FreeFileSync lead to two similar but yet different results: 31 files fail the checksum test, 23 files fail the file comparison test. The smaller set is not entirely contained in the bigger set, although many files occur in both. What is alarming here is that not only JPEGs are flagged as altered but also som AVIs, MPGs and a large 7-zip file. Closer inspection of a JPEG indicates that it is indeed corrupt: the bottom half of the picture is simply plain gray. Due to the size of the 7-zip file, I have not been able to pin down the discrepancy. Note, in both methods, every file has its correct file size after being copied. Question: Any thoughts on what is possibly going on here? I have never had this problem before, and I am now terrified that files get corrupted after simple actions like copy/paste and file sync. Even if I manage to successfully copy the files somehow, I would still like an explanation to this.

• Is there a Windows 7 compatible IPSec VPN client that allows protocol and port specific rules?

  - by Sani Huttunen

  As the title says, I need to find a IPSec VPN client for Windows 7. On XP and Vista we've used SafeNet SoftRemote in which you can set up rules for specific protocols and ports. But SoftRemote isn't compatible with Windows 7. 172.xxx.xxx.1 TCP 1433 172.xxx.xxx.2 TCP 1433 172.xxx.xxx.10 ALL ... Since the VPN gateway is configured this way the client must mirror these settings. I've tried TheGreenBow, NCP Secure Entry, Cisco VPN Client and Shrew Soft VPN but none of these allows you to configure by protocol and port. Does anyone have any other suggestions? EDIT: Forgot to mention that agressive mode is also a requirement. --UPDATE-- I've got some news... I've managed to get SoftRemote to work on Windows 7 x64 through Windows XP Mode. After scouring all corners of the Internet for idéas I had enough information to construct a working solution. This solution will probably benefit other clients as well! You'll find a post here with detailed instructions of how I went about.

• Mac updated just now, postgres now broken

  - by Dave

  I run postgres 9.1 / ruby 1.9.2 / rails 3.1.0 on a maxbook air for local dev. It's all been running smoothly for months, (though this is the first time I've done development on a mac.) It's a macbook air from last year, and today I got the mac osx software update message as I have a few times before, and my system downloaded approx 450mb of updates and restarted. It now says it's on OSX 10.7.3. Point is, postgres has stopped working, when I start my thin server (mirror heroku cedar) as normal, and then browse to my rails app I get: PG::Error could not connect to server: Permission denied Is the server running locally and accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"? What happened? After browsing around a few questions I'm still confused, but here's some extra info: Running psql from command line gives same error I can run pgadmin 3 and connect via it and run SQL no problems Running which psql shows the version as /usr/bin/psql I created a PostgreSQL user back when I got the mac (it's always been on lion) I've no idea why, almost certainly I was following a tutorial which I neglected to store in my notes. Point is I am aware there is a _postgres user as well. I know it's rubbish, but apart from a note on passwords, I don't have any extra info on how I configured postgres - though the obvious implication is that I did not use the _postgres user. Anyone have suggestions or information on what might have changed / what I can try to debug and fix? Thanks. Edit: Playing around based on this question and answer: http://stackoverflow.com/questions/7975414/check-status-of-postgresql-server-mac-os-x, see this string of commands: $ sudo su postgreSQL bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data pg_ctl: another server might be running; trying to start server anyway server starting bash-3.2$ 2012-04-08 19:03:39 GMT FATAL: lock file "postmaster.pid" already exists 2012-04-08 19:03:39 GMT HINT: Is another postmaster (PID 68) running in data directory "/Library/PostgreSQL/9.1/data"? bash-3.2$ exit

  - by Daniel Wright

  I work for a PC Repair company and we are looking into setting up a dedicated machine with externally accessible SATA bays to clone harddrives as a safety net incase something goes wrong during a repair. We currently use a SATA/PATA to USB bridge called MagicBridge and Norton Ghost on any workstation, but we're looking to move away from Ghost. We have a computer with a large RAID5 array with Windows Server 2008 Standard currently installed, but this can be replaced with a flavour of *nix. I have some experience with Clonezilla, but FSArchiver also seems like a suitable replacment too. My Head Technician wants to know if my chosen solution (probably Clonezilla or FSArchiver, but I'm open to free suggestions) is capable of: Cloning a degraded RAID, such as a single drive from a RAID1 mirror without complaining Producing images that are easily mountable (he'd prefer them to be mountable in Windows, but if there is no other easy way, *nix should be fine) akin to Ghost Explorer so individual files can be restored as well as being able to do bare metal restores. My apologies for wordiness but I wanted to be thorough in my explaination. Thanks for any suggestions or tips :) EDIT: I've just found out that Clonezilla has a workaround for cloning RADI1 drives EDIT2: Found the answer to both of my questions, aparently I wasn't phrasing my searches right, could this question be deleted please?

• Can I take my ReadyNAS drive in Raid1 and plug it straight into new different machine?

  - by jacko

  I would assume that I can just take my HDD out of my NAS (in raid1 mirror) and plug it into another enclosure and have it work off the bat but I'd like to make sure... Any ideas? Edit: My current setup is a Netgear ReadyNAS in (hardware) raid1. I'm hoping to replace this with a home theatre type PC (possibly running Ubuntu), and would like to migrate my data without having to do a bulk transfer over my network between the 2 machines. Can anyone confirm the case for the Netgear ReadyNAS? Edit: Ok after further reading it seems that the ReadyNAS Duo formats my drive as ext3 in 16k blocks. There are instructions for mounting a drive into a linux box here: Mounting Sparc-based ReadyNAS Drives in x86-based Linux There is also talk about a linux image here: ReadyNAS Data Recovery - VMware recovery tool I'm not sure whether this means they ReadyNAS actually implements software raid under the hood, or what? So it appears like it IS do-able, but do any of you linux guru's know whether this is viable and whether the fact that they are in raid 1 affect matters?

• Web page layout becomes broken when moved to live.

  - by Moses

  I want to preface my question with the fact that I'm only a front-end web developer, so please excuse my gross lack of knowledge in this area. My company has three webservers: one for development (IIS v5), one for staging (IIS v5), and one for live deployment (IIS v6). Staging is an exact mirror of live. When I compare the staging and live web pages side by side in Firefox (3.6), the pages are identical. However, when I compare the staging and live pages with Internet Explorer (8), there are major differences... In staging, the squares for bulleted lists are small. In live, the squares are big. In staging, the borders for tables are thick. In live, the borders are thin. In staging, an ASP generated image is the proper height. In live, the image is cropped at the bottom by about 10px. In the end, the layout on live became broken because of these tiny differences, but why? Does the fact that live is on IIS 6 and staging is on IIS 5 account for the small variance in display? And is there any way I can change this server side? Also, is there any reason why Firefox displays both correctly and IE displays both incorrectly?

• Clustering filesystem for small files

  - by viraptor

  Hi, I'm looking for a distributed filesystem which I could use for storing lots of small files (<1MB usually). What I want to get is: 2 servers which have the fs mounted themselves and mirror the data locking support (among reachable nodes) some kind of best-effort automatic resynchronisation after one node goes down and comes back again What I mean by the resync is that, I'm ok with both servers doing read/write operations even if they split-brain. I'm also ok if a local process obtains a lock if the other host is not reachable. From the resync I expect only a file-level consistent view after a while - that is - if file x is modified on both nodes during a split-brain, I don't really care which one is available after they join again, as long as it's full file, not one block coming from node1 and another block from node2. Is there a solution like that out there? I see that gluster has some problems with file locks (even in 3.1). I also noticed that OCFS2 will panic if both nodes split-brain. What other filesystem would allow me to do what I want?

• "Safe" personal router use on apartment-wide network

  - by noisetank

  I recently moved into an apartment with internet included in my rent. This was a boon at first, but now I'm feeling limited. To get devices connected (wired or wireless), I have to whitelist the MAC addresses on mycampusnet.com. This is annoying (considering I'm well over the 10 device limit including my roommate's stuff), but what's really driving me mad is that I don't seem to have any semblance of a "local" network. I've relied heavily on static IPs and port forwarding in the past (accessing NAS and remote desktop) and (as far as I can understand), that functionality is nonexistent without my router set up. Also, as my wired and wireless devices don't always seem to make it onto the same subnet, I'm unable to use any of my iDevices with my Apple TV (I can, however, mirror to no less than four strangers' Apple TVs at any moment, which is a whole other level of discomforting). I've talked to the head of the apartment complex and she told me that they personally don't have any issue with my using a router, but the provider (CampusConnect) does not currently allow it. Apparently, enough people have put in complaints/requests about the restriction (the apartments are for graduate students and University staff, many of which need to set up things like VPNs for work reasons) to open up some sort of ticket to get the functionality in place, but all the calls I've made to get status updates have been a waste of time. My question is: If I plugged my router into the apartment network, what would happen? I've been told already that personal routers would "interfere with the wireless" and that they would shut my port down if I used one, but is that a legitimate thing or just something made up that sounds real to keep the average Joe from pushing it further? I'm guessing there's some way of configuring my router to keep it from disrupting the rest of the network, but it's not something they want to tell me for obvious reasons. Am I right? And if so, what are the chances that they'd notice the difference in traffic or whatever and shut off my port?

• Mirroring the Global Address List on Blackberries

  - by Wyatt Barnett

  In times immemorial, back in the day when men were men and blackberries still took AA batteries, we rolled them out to our users for our 100 person operation. At that time, there was no such thing as address list lookups, so we were forced to hack a bit. The ingenious hack we came up with was to mirror the GAL as a public folder and then synch up blackberries to that. While there have been a few downsides here and there, they have been mere annoyances. And our users, having grown fat and prosperous in the intervening years, have been used to seeing every single employee and department here listed on their hand-held automatically. Alas, it appears that Outlook 2010 breaks this functionality as Blackberry desktop manager is completely incompatible with it. Moreover, this presents us with an opportunity to change things for the better given that public folders are going away next time we upgrade exchange. So, we are in search of a tool or technique that will allow us to mimic current functionality--that is to: Push an essentially arbitrary list of ~100 contacts to blackberry address books Said list shall be centrally updated Without requiring desktop manager or exchange public folders. Any suggestions, crowd?
