• Is LDAP typically used in conjunction with SAP?

  - by michael

  I have potential clients that all use SAP. To avoid silent push back from IT, we want to make sure we don't add extra complexity to their job if the client (our client internal to the company is not IT) wants to adopt our SaaS. One way to avoid headaches is to add support for LDAP in our SaaS (a bit of work, but nothing major) ahead of time and make sure to mention that to IT. I really know nothing about SAP. Does SAP use an internal or external LDAP server usually? Updated question: A Company relies on an Asset management product from SAP. If I wanted to provide a SaaS that shares space in their workflow, is it advisable to use the SAP product authentication service (if it exists), and if so, do they provide an API?

• rsync stuck with the --checksum option

  - by billc.cn

  I use back-in-time to backup my Linux installation. It serves as an advanced wrapper for the rsync command. Today I tried to add /var/log to the list of folders to be backed up and it caused some serious performance problems. The job seems to stuck on a particular file and the CPU usage of the rsync parent process reaches 100%. I then used lsof to see which file caused the problem and it seems to be the /var/log directory. I did some googling and some experiments with the different rsync options and found --checksum to be the offender. Without the parameter, an incremental backup finishes properly in minutes. With it, the process will stuck when rsync tries to sync a constantly changing log file. This kind of make sense, but it still seems to be a bug to me. Am I using the option correctly? Is there a workaround for this?

• ubuntu 9.10 on an external usb drive: grub1 does not work

  - by Toc

  I have installed Ubuntu on a partition of my external usb drive. Since I had problems with grub2, I have uninstalled it and installed grub1. But then the usb drive didn't boot anymore, and I am forced to the limited shell of grub1. If I write manually kernel (hd0,4)/vmlinuz-2.6.31-15-generic root=/dev/sdb4 ro quiet splash initrd (hd0,4)/boot/initrd.img-2.6.31-15-generic boot then Ubuntu is loaded, but if I execute the commands root (hd0,4) setup (hd0) as explained at http://www.gnu.org/software/grub/manual/html_node/Installing-GRUB-natively.html#Installing-GRUB-natively, next time I boot from usb I am forced again to the grub limited shell. How can I restore a working grub?

• Resolving Domainnames differently for different services

  - by mlaug

  Some time ago we had an issue with our network infrastructure and php with curl. Our Network infrastructure is fairly simple. LoadBalancer/Firewall = 5 servers The Domainname of our website is set to the ip of the Loadbalancer, of course. But calling curl from one of the servers did result in a timeout. It appears that a server could not call for its own domain it is serving. So we had to set the domains via /etc/hosts to the sever itself. But now We have implemented a Varnish in front of the Loadbalancer, which we want to automatically purge, once a change on a page happens. So now we need to call the domain www.example.com/url_to_purge. Sadly this call what be resolved to the server itself instead of the varnish, because of the /etc/hosts entries. So now I am wondering, if you could resolve domain names differently for different services :)

• Can You Specify Where LVM Snapshots Are (Initially) Stored?

  - by bottles

  Disclaimer: this is my first time using lvm. Upon RTFM, it appears that LVM snapshots are automatically stored in the same directory as the original logical volume. In my case, that would mean the /dev directory. This isn't very nice, because there's not enough disk space in there for me to store a large snapshot. So when I run a command like lvcreate --size 1G --snapshot --name snapshot /dev/lvmData/usr, I need an additional 1G of space free in /dev? Is there any way to specify a different directory in which to store my snapshot?

• Syncing 1TB+ to a iSCSI device, software needed

  - by mojah

  Hi, I need to sync a local disk to a iSCSI mount on Windows (server 2003), and I'm struggling to find software that's capable of doing so in a reasonable timeframe. Notes on the current 1TB disk: - 800GB currently in use - Contains a folder with several hundred thousand subfolders, which in turn have several thousand files, ... So I'm trying to find a piece of software that can handle such large filelists, and give me a good timeframe on when this will be copied. I've tried DeltaCopy (the rSync GUI client for Windows), but it's intolerably slow and doesn't provide me with a good estimate time remaining. DeltaCopy: http://www.aboutmyip.com/AboutMyXApp/DeltaCopy.jsp Does anyone know alternative software for Windows, that would do this well?

• Can I set osx to boot with several spaces containing a different set of apps in each?

  - by Jay

  When my system boots I would love to have it to create three spaces: First Space: email and things (my to do list program) Second Space: textmate and a browser containing first site I am developing Third Space: textmate and a browser containing my second site Is it possible to set it up to do that each time? I'd prefer not to use the reopen windows option on shutdown because most days I have a bunch of things open that I won't need the next day. Thanks. UPDATE: I found TotalSpaces2 and it will open all the same spaces when I reboot. I suppose that I might need some kind of hack to get the applications to start in the appropriate space at boot.

• Disable a driver with a command

  - by user337085

  I have a macbook running Windows on it (with bootcamp). I have external mouse to use, but touchpad remains enabled at the same time. So when I use keyboard, I always click on it and move mouse cursor. The first thing I did is I just disabled driver in devmgmt.msc. But sometimes it could be helpful to disable and enable the driver with AutoHotKey (mapping ^F12 key or whatever). So I just want to know, is there any way of enabling/disabling the driver with a command or registry? In order to be able to do that with AutoHotKey. Thanks.

• I suspect that my HDD is causing hardlocks, as all other components have been replaced. How can I check this theory and solve the potential cause?

  - by user867814

  I have had this problem over quite a while now, thorough multiple Linux kernel versions and distributions, as well as replacement of all components, aside from my main HDD - RAM, GPU(twice), mother board, CPU, power supply. What happens is, at one point during the operation of the PC, it will hardlock - everything stops working, external HDD is not shut down correctly and continues to spin until I plug it out and in, there are no system/kernel logs of any kind, and no otherwise nothing that would suggest a cause. Another reason for my suspicion is that the failures happen almost exclusively during HDD read/write activity - shutdown(happens nearly 1/3 of the time so far, it's only been few days though), launching programs, and once during operation of apt. I hope the post is descriptive enough, if you need any additional info, ask(and tell me how to prepare/obtain it), and I will provide. If I'm wrong, point me in the right direction. Thanks in advance.

• Can't connect to localhost via browser. Can ping localhost.

  - by Sceptre

  I'm trying to connect to localhost through my browser to learn some apache tomcat stuff. When I tried to connect to localhost through Firefox, I couldn't; when I tried through IE, I could the first time, but not after that. I'm using Windows 7, and changed the hosts file to point localhost to 127.0.0.1. I can successfully ping localhost and 127.0.0.1. I have tried turning off my antivirus and my Windows Firewall, but to no avail. What am I doing wrong?

• Server Overload Due To Log File

  - by emresavas

  cPanel sent me the following email: IMPORTANT: Do not ignore this email. This is cPanel stats runner on ***.***.com! While processing the log files for user ***, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is 04:41:14 up 15 days, 22:36, 0 users, load average: 7.66, 7.84, 8.00 You should check the server to see why the load is so high and take steps to lower the load. If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes). How can I lower the load?

• cygwin: ~ != $HOME

  - by user443854

  When I start cygwin, my ~ dir is the same as $HOME. After some time, ~ dir changs, while $HOME stays the same. I am puzzled by this, not sure where to look. Maybe someone experienced this, or has some clue what's going on? When I start: winuser@mybox ~ $ echo $HOME /cygdrive/c/cyguser winuser@mybox ~ $ echo ~ /cygdrive/c/cyguser Later, ~ changes to /cygdrive/c/winuser, which is non-existent. When I restart cygwin, everything is back to normal. What could be causing this?

• Force firefox to open pages in a specific tab using command line

  - by user36306

  Hey Guys, Here's the challenge--I developed Softphone Screenpop PHP App that takes caller id info and searches for a match in our db, also allows us to collect call statistics. Great for our management but it's driving our reps nuts. We use firefox here and when our softphone pops to the external page, every time it opens in a new tab, the girls quickly get 5-10 open and it becomes confusing. Our softphone will also run command line. I wondering if there is a way to have a URL open in a certain tab. Otherwise does anyone have any other ideas? Thanks!

• Large OSX 10.6 to Windows 7 smb transfers fail?

  - by user41724

  I'm connecting to a windows 7 box from a OSX 10.6 box via smb: smb://ftp1 Connection works fine, I can transfer individual files one at a time, but as soon as I try and move an entier folder I get the following error: The Finder can’t complete the operation because some data in “test” can’t be read or written. (Error code -36) This error happens on all our OSX boxes when trying to push the entier folder to the Win7 box. The folder TEST in the above error message has -R 777 permissions. I can move every image file to the windows box one by one with no errors. But if I try an move the entier folder. bam error out. This error seems to kill the smb client on the Windows box as well. There's an FTP server on the windows box and I can FTP in from the OSX box and move everything just fine. Not sure what is going on here?

• Is it possible with Google searches to ban any and all results from a domain? [closed]

  - by Stu Thompson

  Is it possible to configure Google somehow to permanently ban search results from domains that I know 100% are never, ever going to make me happy? Something cookie/session based maybe? E.g. I want to ban (permanently, forever and always) results from experts-exchange.com. Every time I click results that take me to their page I just want to scream. Update! Google has released a Chrome Extension to allow users to block individual site from Google search results! Personal Blocklist (by Google). (Since this question has been closed, I cannot answer it.)

• Continue process after closing terminal?

  - by Jakobud

  Recently, I tried to unzip a 30 gig zip file on a remote system using Putty. As the long unzipping process continued, I closed Putty, assuming that the process would just continue to run on the remote machine. When I came back later and logged back into the machine again, I realized that the process must have stopped only part way through when I closed Putty. I wasn't expecting that to happen. My question is, how do I prevent this problem? Can I somehow fire off a process in the background? Or should just setup a one time cronjob that will run the process for me?

• How can WiFi access points recognize me?

  - by stephanos

  Due to heavy snowfall I was recently stranded on an airport. Having to do some surfing on my laptop I found an open access point. It offered 30 minutes of free surfing a day. I registered and used up my time. Then I wanted to see if I could use it again - mostly just for the fun of it. I opened a different browser then before and tried to register again. It didn't work. The access point recognized me and told me that I'd have to wait another day to get 30 free minutes again. I reconnected again to force a new IP - still the same. How did it recognize me?

• parallel vms in VMWare Server - how to configure network so they can ping each other?

  - by IronGoofy

  I'm using VMWare Server (currently on Version 1.0.7) and have two VMs that I would like to run at the same time. However, I'm having problems in setting them up so they can ping each other. I've configured them to use 'Bridged' networking. They both obtain an IP address from the DHCP server on my network, but after that they can't ping each other. It seems that only the first one has a functioning network connection (I can ping it from the host machine and Internet connection works), but the other one does not. If it helps, both VMs are running XP SP 3. Any ideas? Thanks!

The servers firewall is open to the client's subnet. The mysql user has permissions from the client's subnet. I have my host looking into the problem but so far we're all stumped as to way the occasional connection is (increasingly getting refused) Any advice what to check that would cause the random refusal of connections?

• Why are my favorite websites becoming slower, over months?

  - by Wolfpack'08

  I spend a lot of my time at sites for watching online videos: youtube, gorillavid, thedailyshow.com etc. I used to watch the videos in full screen mode, and then that became very laggy. So, I started watching them with full-browser zooming. Then that became laggy. Recently, I've had to actually zoom out; otherwise, the video will lag so much that my PC locks. Could this be a symptom of my processor, RAM, or motherboard going bad? Has it, perhaps, anything to do with softwares like Chrome or the playeres the sites are using being updated?

• Route SOAP request through external server

  - by sanbornm

  I need to integrate with a SOAP Web Service that requires that the requests come from a whitelisted IP address. As I often do development from all over the place it is quite annoying to ask for a new whitelisted IP each time. I have a remote server that is whitelisted. How can I route my SOAP request (I can change the endpoint in the WSDL) to my remote machine and have that forwarded to the Web Service? My remote server is used for other things so it needs to only forward a specific port, not all traffic. Oh, and the Web Service expects SSL.

• IntelliPoint & Intellitype upgrade to Mouse and Keyboard Center causing system freeze?

  - by Kent England

  I allowed Microsoft to upgrade my wireless keyboard 6000 v3.0 and mouse 6000 v2.0 from Intelliyada v 8.20.468 to what appears to be v9.1.486. This was some time ago, so I can't be certain but this upgrade might be causing my system to freeze on the logon screen (user selection) in Windows 7 Home Premium 32-bit. Mouse and keyboard don't work, but system seems to be running underneath. No indication in Event Viewer about keyboard/mouse driver issues. Might be problem with transceiver hardware. I now have the "Microsoft Mouse and Keyboard Center" UI which isn't very helpful (seems to be very metro) in debugging these drivers. I'm just looking to see if anyone else had problems upgrading to this new Intelliyada software for their MS keyboard and rodent.

• pine sometimes not update new received emails

  - by Tim

  Hi, I am using pine on a KUbuntu linux email server to check my emails. Most of the time when I am under "Inbox", the list of emails is updated automatically so I don't have to do things like pushing the refresh button when I am under web. But sometimes it does not and I have to type "<" to go to the upper level and then select "Inbox" to enter again into the inbox directory to find out that I do receive new emails that are not shown previously. I was wondering what the problem is? Thanks and regards!

• Customising error bars

  - by itid

  Hello I've been told I HAVE TO have custom error bars for an assignment I have to hand in. Okay, I have a scatter graph with twelve points, and the error for each one is different. It's the same plus and minus, but different for each one. The twelve different error values are sitting nicely in a column. I have been told I can reference that column in "custom error bars" simply by indicating the range of values, like F2-F14. However, I get an error message every time. When I open Custom Error Bars, it is set up like this: ={} obviously waiting for a function. The error message says remove the equals sign. How should I enter the value range, please ?
