• Windows mounted network drives slow after upgrading switch

  - by Kver

  On our small business network our old 10/100 consumer grade switch gave up the ghost, and we replaced it with a proper business-grade gigabyte switch. After wiring it in our Linux and Mac users immediately got back to working off of network drives; But 2 of our 3 Windows 7 PCs have suddenly experienced a tremendous slowdown with mapped network drives; Windows will become stuck "discovering" a folder causing applications to freeze when trying to open files. It will instantly display and browse files, but the moment you try to open one the bug hits. To remedy this we have our users copying files to the desktop, but it can take a few minutes while windows is stuck "calculating" the time it will take to copy. These aren't big files, mostly excel sheets less than 500KB - these operations are instant on Linux and Mac. (The third Windows machine is having no issues) I've tried remapping the drives, mapping to different drive letters, rebooting, etc. I'm at a loss, because switches are mostly transparent, and it's only after the switch was replaced that the Windows PCs started acting up. What black-magic voodoo am I missing to make Windows work? Thank you.

• Internet connection problem,ping ok , but outlook and browsers dont work

  - by Ashian

  Hi, From some days ago I have a big problem on my laptop( run windows xp sp3) When I connect to internet I can ping web sites but when try to browse them some times it work correctly and some times the connection to server intrupted and I have to refresh the page several times. in this case browser show a connection problem immediatly after I click on address bar or a link on page( wihtout any try to connect to server) I use FireFox and opera and both of them have this problem. try another ISP and still I have this problem. I didnt use any proxy server and check the proxy setting. In this case Outlook also can't connect to mail server. this problem anfter some time or after restart windows have been fixed for a while. I check for virus and can't find anything. Is there any idea how can I fix it? UPDATE: Thanks for your responses.

• Proxmox: VMs and different public IPs

  - by Raj

  I have a server which has two NICs and both are directly connected to internet. I have five different public IP addresses available for the VMs. The host machine (Proxmox) doesn't need to use any (it'll use a private IP and that's all) but will have internet connection. I've gone through the Proxmox documentation and I'm not able to understand the big picture to set up the right network configuration for my needs. In short, what I have is: One server (Proxmox, host machine) On that server, 5 VMs are created 5 public IP addresses available (one for each VM), let's say: 80.123.21.1, 80.123.21.2, 80.123.21.3, 80.123.21.4, 80.123.21.5 What I have now for the host is the following: auto lo iface lo inet loopback auto eth0 iface eth0 inet manual auto eth1 iface eth1 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.1.101 netmask 255.255.255.0 bridge_ports eth0 bridge_stp off bridge_fd 0 auto vmbr1 iface vmbr1 inet manual It can be reached from the internal network, so that's OK. It has internet connection, which is also OK. vmbr1 is going to be used by the VMs. Each VM will have its own IP on his network interfaces configuration file. For some reason, VMs will not have internet and they won't be able to have public IP address. If I use NAT, it will work correctly, but they will not use the public allocated IP addresses for them. Am I missing something?

• Managing SharePoint permissions via Active Directory?

  - by rgmatthes

  My company has thousands of employees organized thoroughly via Active Directory. I have confidence in the accuracy of the Department and Title information displayed in the user profiles. I'm helping to put up a brand new SharePoint 2007 site, and I contacted IT about managing the site's permissions through AD Groups. The goal is to have the site automatically assign read/write/contribute/whatever permissions based on the information in AD. For example, we could create an AD Group called "Managers" that would contain anyone with the "Manager" title in their AD user profile. I would have SharePoint tap into this AD Group to mass assign permissions if I knew all managers would need a certain level of access (read/write/contribute/whatever). Then if a manager joins the company or leaves it, the group is automatically updated (provided AD gets updated, of course). My IT rep called back and said it couldn't be done. This seems like a pretty straightforward business requirement, and one of the huge benefits of having Active Directory, but maybe I'm mistaken. Could anyone shed some light on this? A) Is it possible to use dynamically-updated AD Groups when assigning permissions via SharePoint? (Does anyone know of a guide I could show my doubtful IT rep?) B) Is there a "best practice" way to go about this? I've read some debate on whether SharePoint Groups or AD Groups are the way to go. My main concern is dynamic updating. C) If this isn't available out of the box, can someone recommend third-party software that will provide the functionality I'm looking for? A big thanks to anyone who can help me out!!

• How can one keep secure regular backups of his desktop on a remote server through aDSL? [on hold]

  - by Antonis Christofides

  I'm a system administrator and I use rsnapshot to backup some servers, duplicity for some others. Both work fine, each one with advantages and disadvantages. Despite that, I am at a loss on how to backup my own private files. I'd use duplicity to automatically backup my files to a remote server; but the problem is that once in a while I must do a full backup. My emails and important files are 9G, and I expect this to increase. Uploading through aDSL at 1Mbit would be 20 hours. Too much. rsnapshot doesn't require periodic full backups (only the first time), but it must be running on the remote server and have a means to connect to my computer; if the server is compromised (or simply if the NSA decides to use it), my own machine is also compromised. Not good. The only solution I've come up with is use encfs, use unison to synchronize the files to a remote server, and use duplicity or rsnapshot on the remote server to backup these files. In that case, the question is whether I can sync the files on many computers; is it possible for encfs to be used with the same key on many computers? I also think that if I append one character to the unencrypted file, its encrypted encfs counterpart might change a lot, so that incrementals with duplicity would be less efficient—but not a big deal. Maybe also, when I need to restore a file, finding the correct file to restore could be a pain, because of filename encryption. I wonder whether there is any other possibility that I've overlooked. Maybe I'm asking too much for my personal use, and I should settle with an external disk?

• SQL Server 2005 to 2008 DB attach elp please!

  - by Brandon

  I have SQL Server 2005 Standard on my personal machine. I created a very big DB about 21 gb. I made a backup and transferred the .bak file via an ftp program to my dedicated server. I have SQL Server 2008 Enterprise Edition on my dedicated server. I tried restore the transferred .bak file but got an error. I posted the error on here and was told the database is corrupt. How? I don't know. The connection was not interrupted during the ftp transfer. The DB works on my own machine. So then I detached the db on my own machine and transferred the mdf and ldf file to my dedicated server through ftp again and again there were not interruptions. Now I try to attach the db and get this error: The header for file 'DB.mdf' is not a valid database file header. The FILE SIZE property is incorrect. (Microsoft SQL Server, Error: 5172) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.00.1442&EvtSrc=MSSQLServer&EvtID=5172&LinkId=20476 I already wasted 21 gb transferring the .bak file. Now I used another 21 to transfer mdf and additional ldf file. Please tell me there's a solution. The db can detach and attach fine on my machine in sql server 2005 but not SQL server 2008 on my server.

• quad sli with gtx 690 not working

  - by Moaadh

  I have two cards GTX 690 (dual core). I did the Sli successfully. Nvidia control panel acknowledges the two cards as quad Sli. However, the problem is that Windows 7 64-bit Ultimate is showing me the graph memory size as 4 GB while it is supposed to be 8 GB because of the Sli. Also the benchmark from all software is giving me a very low score compared to some other guy's benchmark on YouTube. It gives me a big headache. Does anyone know why this is happening? If so, how can I get Windows 7 to recognize all 8 GB of memory? Thanks for your help in advance. My computer specifications: (Processor: Intel Core i7-3930k @3.2GHz(12CPUs))--- (Memory: 65536 MB Ram 1866 MHz)-- (OS: Windows 7 Ultimate 64-bit)-- (OCZ 240GB as SSD PCIe drive for booting and storage disk)-- (DirextX version: DirectX 11)-- (VGA Card: 2 X EVGA GTX 690 Dual GPU. Each GPU is 2 GB, so total memory should be 8 GB.)-- (MotherBoard: ASUS Rampage IV Extreme)-- Others with lesser specifications get a 2500 score in heaven benchmark while I get 1501 as if it is one card.

• Fill down in Excel, but based on multiple values

  - by Jenn D.

  I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

• Office 2010 Trust Center settings: How to enable data connections in the "old" way?

  - by GSerg

  We're planning an upgrade Office 2003 - 2010 and have identified a big problem. In Office 2003, if the workbook you're opening contains a query table that fetches data from a data source automatically (upon file open or in certain intervals), then a security dialog pops up - whether you want to allow that. If you say Yes, the queries will refresh automatically when they need to. If you say No, the queries will not refresh automatically, neither on file open nor on time intervals, but you will be able to refresh any of them manually at any time by right-clicking and selecting Refresh. There is also a registry parameter to say, Don't display that dialog, just allow the queries. This is exactly what we want. On users' computers we have the registry parameter applied, so the users never see any dialogs. On developers' computers the parameter is not applied, so every time a file is opened the developer decides whether to allow the auto-refreshing for the current session. Usually the answer is No, because for developing, it is essential to not have quieres refresh when they want to, but instead, refresh them when the developer wants. The problem is that in Office 2010 which we are testing we can't find a way to achieve this functionality: The allow/disallow messages are now grouped into one yellow button, that either allows everything or disallows everything (including, say, macros, if macro security is set to "Disable, but ask"). If you don't click the yellow Allow button, the queries are disabled completely, not just for automatic execution. You cannot right-click and refresh a particular query -- doing that would summon a security dialog prompting for enabling queries, and if you say Yes, all queries in the document will be enabled for auto-execution and will start executing immediately. This sort of ruins our development environment. Is there a way to get the trust thingies in Office 2010 to work in the same way as before? Is there a yet another registry parameter to say, Prompt for auto-refresh, but allow manual refresh even when auto-refresh is disabled?

• Industrial strength cloud file storage

  - by ArthurG

  I'm looking for an industrial strength cloud file storage system. It will be used by multiple people in a startup. Our requirements: Transparent file system access: files and folders in the file system must be able transparently access (read and write) files in the cloud; files must be synchronized whenever network access is available and buffered otherwise. The system must be usable by non-technical people. Access control: we need to control who can access which files, at least on a very coarse basis. e.g., the developers will be able to access the system design documents, only the corporate folks can access recruiting documents, and only management can access certain corporate documents. Dropbox provides this via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. so the cloud service should have a notion of an account (our startup) with multiple users with distinct credentials and rights for each user Clients: it must be accessible from Macs and PCs; I would hope that it supports Linux (e.g., Ubuntu) too Security: it must provide robust security Backup: the cloud service must reliably backup the files Versioning: change version history, is a big plus, but not required Not free: we're willing to pay for the service So far, we've reviewed the following, albeit not completely thoroughly: Dropbox: has all except 1) Access control, which is provided via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. and 2) Security, as discussed here http://www.economist.com/blogs/babbage/2011/05/internet_security and here http://blog.dropbox.com/?p=821. Windows Live Mesh, has all except 1) Clients, only supporting Windows 7 and OS X. SpiderOak has all, except 1) Transparent file system access, which is only available for 1 user. Amazon Cloud, doesn't offer 1) Transparent file system access Rackspace Cloud Drive has all except 1) Access control and 2) Versioning I'll gladly include any clarifications or additional systems the community provides.

• Recommended drive encryption solution

  - by Chris Driver

  Hello, I will soon be purchasing a number of laptops running Windows 7 for our mobile staff. Due to the nature of our business I will need drive encryption. Windows BitLocker seems the obvious choice, but it looks like I need to purchase either Windows 7 Enterprise or Ultimate editions to get it. Can anyone offer suggestions on the best course of action: a) Use BitLocker, bite the bullet and pay to upgrade to Enterprise/Ultimate b) Pay for another 3rd party drive encryption product that is cheaper (suggestions appreciated) c) Use a free drive encryption product such as TrueCrypt Ideally I am also interested in 'real world' experience from people who are using drive encryption software and any pitfalls to look out for. Many thanks in advance... UPDATE Decided to go with TrueCrypt for the following reasons: a) The product has a good track record b) I am not managing a large quantity of laptops so integration with Active Directory, Management consoles etc is not a huge benefit c) Although eks did make a good point about Evil Maid (EM) attacks, our data is not that desirable to consider it a major factor d) The cost (free) is a big plus but not the primary motivator The next problem I face is imaging (Acronis/Ghost/..) encrypted drives will not work unless I perform sector-by-sector imaging. That means an 80Gb encrypted partition creates an 80Gb image file :(

• Suggestions for Backup solution

  - by jiewmeng

  i am considering between windows home server simple nas extra HDD's in desktop btw, i will be the main user i am looking to fulfil the following needs: reliability (i am think RAID 1 or 5) not so prone to virus/malware infections (will using a separate NAS or home server help? say windows home server is still a windows pc except separated by network?) power efficiency (eg. spin down when not in use) download (eg. i may want to dl big files/torrents overnight and i may not want to use a full powered PC for it? does a full pc vs NAS provide significant power usage to justify cost of new system esp. since i am only user?) performance (i guess i like to write/access my files fast, on 2nd thought, maybe for backup i can forgo this? maybe for a WD Green HDD? but how much slower will it be? plus since i am the only user, i think the whole HDD will be mine?)

• How can I optimize my ajax calls to deliver at 60ms.

  - by Quintin Par

  I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

• What does it mean to install two OS's alongside each other?

  - by Josh

  I currently have Windows 7 installed on my PC. However, I just tried out Ubuntu via booting from a disc and I love it. I want to install it onto my HDD, but I don't want to get rid of Windows 7. I know HOW to do this, but I am a little unsure what the consequences might be. What does it mean to install Ubuntu alongside Windows? Do they share the same resources? Also, I have my HDD already partitioned into two sections, a 70 GB section where Windows is installed and then another 400 GB section where all my data is stored. There is currently 26 GB free on the 70GB partition. I know Ubuntu doesn't take up much space. However, if I install Ubuntu in that space, will I still be able to install programs on Windows in the future? My main concern is that I am going to short-change my hard drive space for future installations. EDIT: I guess another big question I have is if I install a program on one OS, will the other be able to use it?

• How do I make a PPT file as small as possible?

  - by grunwald2.0

  Currently I am agonizing over several large presentation files, which I happened to reprint to PDFs... One thing I wondered: Do PPT's (from Microsoft Powerpoint) always to have to be that big? And what would be the strategies to make a PPT smaller? (If we say "ceterus paribus" at e.g. 25 slides and assuming that one isn't allowed to use a cloud-based service like GDocs, rocketslide or Prezio.) Of course there are the obvious "bad guys": Images and graphics. But: How about roll-over animations etc, who knows how much space they take? How about "smart arts"? Could one save file size if one would use "Open Office" or "Libre Office" Impress? (I didn't try it yet.) And "what if": What if we need to include e.g. five images (or charts that can't be remade in Excel in time), how would we best reduce the file size impact of those five images, if we needed to? I ask all this from an honest "business" perspective. I am no nerd or "Microsoft MVP" and I don't intend on delving into LATeX or similar yet. But that doesn't mean that I am not curious and very willing to learn. I am basically interested in (proven) best practices. Yes I know this question is lacking "initial research", but I think the perspective of my question is interesting and unique to a lot of people and if we intend to make SE a "Q&A" / Wiki kind-of reference site, this question might be a good way to "collect" advice on a question that has a very defined goal: Minimum file-size.

• Broken Vista. Can't open Windows settings.

  - by serena

  My neighbor has a Lenovo laptop with Windows Vista Home Basic. She's a noob and just uses the laptop for internet purposes. She said she had to close down Windows improperly (sometime ago, maybe 6 months) because of system freeze. She realized there's something wrong with her Windows when she tried to open Windows update settings. I took a look at the system and determined the following errors: When I click on Windows Updates, a bare white window opens for a sec. and closes immediately. When I try to open Computer Properties, the same thing happens. (Windows+Break doesn't work either.) When I try to open Bluetooth settings, the same thing happens. So Vista won't let me open any Windows settings, but installed programs work correctly (games, applications etc.). She has no Windows Vista discs since the laptop came with preinstalled genuine Vista. She also has no recovery discs. I don't think there is a system restore point for the time the system was stable. Now what can we do to solve this big problem?

• VGA Cable gave me an Electric Shock when connecting a Projector to a Laptop

  - by Felipe Luarte

  Yesterday I was trying to connect a Viewsonic Projector to my Samsung RC420 laptop... I followed this steps: I Plugged the Projector to a power source, in parallel I did the same thing with the laptop. Then I turned on the laptop, but not the Projector (this one turns a bright light when is connected to a power source). I put the VGA Cable to the Projector (this one being still turned down) and then when I was getting close to the VGA port of the Laptop... BAM! A big spark appear between the port and the cable! Immediately the whole electricity of my floor went off. A part of the port in my laptop kind of... melted down. It seems to be where the spark started. The same thing happened to the part of the cable involved. Now I'm using the laptop, and it seems that there is no problem in it, I haven't connect anything to the VGA port yet. And the projector is still working to, well... it turns on, and I haven't connect anything yet too. The projector was connected to the power source by a homemade electric extension.

• Windows 7 doesn't start anymore

  - by 0xFF

  I've experienced some BSOD on windows 7 RC, and some freezing when startup, but today was big surprise, it doesn't start anymore. I tried to start on safe mode and no results too, it shows the starting animation, then a blue screen for less than a second and turns off immediately. The only thing I remember did today is update flash player under Firefox, then chrome stopped working even after logging off, and once restarting, it doesn't start anymore. Anyone experienced the same issue? any hints? [EDIT 3] Solved : Windows 7 have a very smart repair strategy, it works automatically, and it tried every possible fix, what fixed my problem was the system restore to a previous date, all this happened automatically.

• How do i play nicely with MS SQL/SQL Server 2008

  - by acidzombie24

  Big problem. I have nearly given up. I am trying to port my prototype to use MS SQL so it will work on a server once i get it (the server will be SQL Server 2008, shared, i dont know any more info). So i tried to connect to SQL Server via visual studios IDE and had no luck. I enabled TCP and named pipes and restarted the service (and computer) with still no luck. I remembered about mdf files so i made that after an obstacle of not being able to make the connect string require i figure out visual studio has it in its properties and successfully connected with that. Then i had a problem with nested transactions. After not being able to figure out how to check i wondered if i can configure it to allow it somehow. I always thought all of MS were the same except for limitations but sql server seems to support nested transactions so theres no point trying to work around the problem with .mdf files since i wont need them and really just used it to port the base of my sql code and to check if syntax is correct. I tried installing SQL Server Management Studio since people mentioned it several times (as a solution or at least help). When installing it on windows 7 it says it may not be compatible. After running it, it launched SQL Server Installation Center (64-bit) which doesnt seem to be the same thing as i dont see a way to modify any of my server (networking) configurations or edit user permissions, etc. I am clueless what to do next. Does anyone have any ideas? I'm posting here bc i think my problem is more configurations and sql server then programming.

• Managing SharePoint permissions via Active Directory?

• Nexenta, NFS and LOCK_EX

  - by Givre

  I'm currently using an LAMP architecture and I expect a big problem :( I have several http web server using PHP5. All are mounting via NFS (v3) the directory for all the hosted websites. The file server is running the Nexenta Storage Appliance using ZFS . The problem is all the NFS client trying to write something in a file over the NFS get this problem : This is inside the apache2 process: open("/nfs/website1/file.txt", ORDWR|OCREAT, 0600) = 11647 fstat(11647, {stmode=SIFREG|0600, st_size=23754, ...}) = 0 flock(11647, LOCK_EX And the process never get the LOCK and keep waiting for... always. The effect? All the apache2 procces get used and waiting.. my severs can't still proccess the others requests because there is no more proccess available. I don't now where to find a solution.. for me it.'s on the NFS server side.. but wich configuration is wrong or missing ? How can I find what is wrong? If you need more information about the configuration, just ask me what can help you more :)

• CPANEL ModSec2 not working with SecFilterSelective

  - by jfreak53

  Ok, I have cPanel/WHM latest on a Dedi, here are my specs on apache: Server version: Apache/2.2.23 (Unix) Server built: Oct 13 2012 19:33:23 Cpanel::Easy::Apache v3.14.13 rev9999 I just ran a re-compile using easyapache as you can see by the date. When running it I made sure that ModSec was selected and it stated in big bold letters something to the effect of If you install Apache 2.2.x you get ModSec 2 So I believed it :) I recompiled, I then ran: grep -i release /home/cpeasyapache/src/modsecurity-apache_2.6.8/apache2/mod_security2.c Hmm, the file is there but grep doesn't output anything, if I run: grep -i release /home/cpeasyapache/src/modsecurity-apache_1.9.5/apache2/mod_security.c I of course get the ModSec 1 version output. But the thing is that ModSec2 is installed since the c file is there. So I continued and put the following in modsec2.user.conf: SecFilterScanOutput On SecFilterSelective OUTPUT "text" Now when I restart Apache I get this error: Syntax error on line 1087 of /usr/local/apache/conf/modsec2.user.conf: Invalid command 'SecFilterScanOutput', perhaps misspelled or defined by a module not included in the server configuration Now supposedly this is supposed to work, I even have it running in ModSec2 on a non-cpanel server setup manually. So I know ModSec2 supports it. Anyone have any ideas? I have asked this question over at cpanel forum and it got nowhere.

• Network bandwidth usage dashboard?

  - by SkippyFlipjack

  I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

• Rsync root files between systems without specifying password

  - by xpt

  This seems very tricky to me. I've set up my two systems so that I can rsync files between them as me, without specifying password. Now the the problem is to rsync files that belong to root. On both of my systems, there are no root passwords. The only way to become root is via sudo. So I can neither give a password for sudo rsyn local root@remote:, no use my ssh-agent to supply pass phrase. I don't want to set up a root password on any systems; and I do need the files to be owned by root on both systems. EDIT: Using the files that belong to root is just an example, I need a way for my unprivileged account to read/write system (including root-owned) files easily. One example is to copy my configured /root environment into the freshly-installed system. The two systems are actually two VMs under a single host, so it's not a big concern for me to copy root-owned files between them. EDIT 2: If I only want to copy my configured /root environment into the freshly-installed system, I can use tar: sudo tar cvzf - /root | ssh me@remote sudo tar xvzf - -C / But I do need rsync to update from time to time. Any easy way to make it happen? EDIT 3: Formally formulate the question Alright, it all began with the question, how to rsync files that belong to root between two systems as a normal unprivileged user, without specifying password, under the condition that, The root account is locked on both of systems. I.e., there are no root passwords. The only way to become root is via sudo (recommended security practice, see http://help.ubuntu.com/community/RootSudo) I don't want a completely passwordless sudo but don’t want to be typing passwords all the time either. The normal unprivileged user has entered their ssh pass phrase into the ssh agent. Thanks
