  • Create a Stream without having a physical file to create from.

    - by jhorton
    I'm needing to create a zip file containing documents that exist on the server. I am using the .Net Package class to do so, and to create a new Package (which is the zip file) I have to have either a path to a physical file or a stream. I am trying to not create an actual file that would be the zip file, instead just create a stream that would exist in memory or something. My question is how do you instantiate a new Stream (i.e. FileStream, MemoryStream, etc) without having a physical file to instantiate from.

  • How to enable an active/active file server cluster in windows 2008 r2 Enterprise

    - by Phygg
    I've just created a cluster for my file servers in Windows 2008 R2 Ent SP1 environment. The goal - an Active/Active cluster for web server data How do I go about telling the cluster to be active for both nodes? Do I have to tell the cluster to be active/active? Here is a link to the instructions I followed when configuring the failover cluster. http://technet.microsoft.com/en-us/library/ff182326(WS.10).aspx So if anyone can help me to grasp the concept or maybe I'm way off and I need a node that is not active along with 2 active nodes to do this, I would appreciate it.

Can this be done by transferring the file to the browsers storage area or taking the file from the Harddrive and transferring to the User's RAM?

  • Schedule a batch file with parameters containing spaces

    - by Danilo Brambilla
    Hi, I need to schedule a task in Windows Server 2003 that executes this script that deletes files older that n days in the specified folder. The script needs 3 parameters: %1 path to folder where files need to be deleted %2 file names (es. *.log) %3 number of days @echo off forfiles -p %1 -s -m %2 -d -%3 -c "cmd /c del /q @path" The script works fine if the first parameter has no spaces inside. This is an example of parameters that work: "C:\Program Files\SCRIPT\DeleteFilesOlderThanXDays.cmd" N:\FOLDER\FOLDER *.zip 60 This is an example that does not work: "C:\Program Files\SCRIPT\DeleteFilesOlderThanXDays.cmd" N:\Program Files\LOG *.zip 60 This does not work too: "C:\Program Files\SCRIPT\DeleteFilesOlderThanXDays.cmd" "N:\Program Files\LOG" *.zip 60 I think it would be a quotes problem but I can't figure out the solution. I'd like not to insert values directly into the script if possible Thank you all for help

  • Can't access network share with name defined in hosts file

    - by Einar Egilsson
    I have a network share on a machine that I can only reach by IP address. I then defined an alias for the IP in my hosts file so I could use that instead of the IP but then I can't log on to the share, I just get the logon prompt again and again. So basically this: \\172.17.0.48\SomeShare works but this \\myalias\SomeShare doesn't. myalias is defined in c:\windows\system32\drivers\etc\hosts as 172.17.0.48 myalias And I can use the alias for remote desktop without problems. Can anyone tell me why this doesn't work for fileshares?

  • Run disk error check on NTFS file?

    - by paulius_l
    I have a feeling that my system hard drive is dying. Benchmark kind of enforces it. Here is the benchmark of my system hard drive during low system activity: And here is the benchmark of backup drive: Furthermore, there are some files which I just can't touch because I get CRC errors and the hard drive activity spikes to 100% with operating speeds less than 1 MB/s while working with such files. I haven't yet tried swapping SATA cable as I have read this might cause the problems. Anyway, I would like to run some tests on specific clustsers where those files I am interested in are stored. I don't want to do the full chkdsk because it takes a very long time. I would like to either find the utility which executes the disk check directly on the clusters where the file belongs or a couple utilities where one tells me the cluster locations and another can check just those locations. How do I check and possibly fix disk errors where the files I am interested in are stored? Edit: S.M.A.R.T. info:

  • "remote file operation failed" on Hudson

    - by Aveen
    I am running a Windows slave for Husdon 1.337 (Linux master). When running a project on the Windows node, it fails with the following message: Building remotely on winTestSlave Checking out a fresh workspace because there's no workspace at C:\hudson\***\ejb remote file operation failed It did work yesterday and I have not upgraded Hudson or changed its configurations (or the slave's configurations) in any way. I establish the connection between the slave and the master by running the following command on a cygwim prompt on the slave: java -jar slave.jar -jnlpUrl http://myserver/computer/winTestSlave/slave-agent.jnlp I saw the issue http://issues.hudson-ci.org/browse/HUDSON-5374 and did as instructed in the work-around but that did not work. I also tried with a newer version of slave.jar (version 1.356) but that did not work either. Does anyone please have any idea of how to fix this? I really cannot find more information anywhere else!

  • [PHP] Read and write to a file while keeping lock

    - by Znarkus
    Hi! I am making a simple page load counter by storing the current count in a file. This is how I want to do this: Lock the file Read the current count Increment it Write new count Unlock file/close it Can this be done? As I understand it, the file can't be written to without losing the lock. The only way I have come up with to tackle this, is to write a character using "r+" mode, and then counting characters.

  • Slow write speeds on new Gigabit home file server

    - by Ryan Holder
    So I finally got all my parts delivered to setup a home file/backup server this week. It's currently running Ubuntu Server and I'm using Samba to share files on my network. The server currently has a 2TB WD Green drive in it connected to a Asus M5A78L-M This is then connected via CAT6a to my new Gigabit switch (TP-Link TL-SG1005D). My home desktop is then also connected to this switch and again also through CAT6a cable. Currently when transfering files I will get a perfect 100MB/s read from the server to my Windows machine. When copying from my Windows machine to the server I get around 30/38MB/s. I know this drive is capable is faster speeds so would anybody have an idea of where the bottleneck is? Any help would be greatly appreciated :) EDIT: I have found ftp's write speed is much closer to what my Samba read speed is so I'm going to give it a guess that is a software problem rather than hardware

  • SAMBA and Linux ACLs -- "Permission denied" on write to share but file written nevertheless

    - by MCH
    I set up a writable share directory "/home/net/share" with acl like this: sudo mkdir -p "/home/net/share" sudo setfacl -m "u:localuser:rwx,u:remoteuser:rwx,g:users:rwx" "/home/net/share" My /etc/samba/smb.conf looks like this: [global] workgroup = w server string = server security = user load printers = no log file = /var/log/samba/%m.log max log size = 50 dns proxy = no printing = bsd printcap name = /dev/null disable spoolss = yes encrypt passwords = true invalid users = nobody root follow symlinks = yes wide links = yes [share] comment = Writable by localuser and remoteuser path = /home/net/share valid users = remoteuser read only = no public = no printable = no Locally, localuser and remoteuser have user accounts and smbpasswds and can both read, create and delete files in /home/net/share. But when I log on from a different machine (like this: sudo mount -t cifs //server/share mountpoint/ -o username=remoteuser ), I get "Permission denied" both when trying to create directories and files, oddly though, it does create files (not directories!) despite these messages! How can I get this working?

  • Locked out by changing file permissions

    - by Valeriy
    I just locked my root account (and all other accounts if it matters) completely out of the RHEL 5.4 by changing permissions on every file to 400. Now I have "Permission denied" on any command that I try to run, including chmod itself. Any idea on how to recover? The only access I have to the server is via terminal or SSH. (If anyone cares how it happened, I was running a hardening script and one of the lines was supposed to change permission on some config files in /etc directory. It has couple of variables that had not been set, so the command essentially evaluated to chmod -R 0400 /* Ouch! This is sure a great lesson on checking the scripts even more carefully in the future but what can I do now?

  • Sending a file to uCLinux

    - by Mike
    I have a board running uClinux, and I need to send a file to it, but I'm not sure how... I have a RS232 port, and Ethernet port with an IP address at my disposal, I can telnet to the board, but uCLinux doesn't have a built in FTP client. What sort of options do I have here for transferring files from my Windows 7 (or OpenSUSE) machine(s) to this board? EDIT I just found I have a TFTP server on it: # tftp BusyBox v0.60.5 (2012.07.09-14:05+0000) multi-call binary Usage: tftp [OPTION]... HOST [PORT] But I can't find any good information on how to use TFTP. And looking around google I'm seeing it's good for loading binary images, so I'm assume anything could be sent, but I'm not sure.

  • How to execute a program from file descriptor?

    - by stribika
    I need to execute a file when I only know the descriptor. It is also possible that there are no links to the file so finding out the name somehow is not an option. All the execve(), execvp(), etc functions take a file name. dlopen() also takes a name. Ugly solutions (like reading the file and calling some function pointer) are OK.

  • Unix file permission for groups

    - by GOPI
    I am working on HP Unix server. I have a directory in which users from different groups need to create files. And the users of a same group should have complete access to the files created by their group and only read access for the files created by other groups. I tried to set sticky bit for the directory thereby to restrict access for other groups. But I face the following problem. Created File1 from user1 of GroupA. When I tried to execute the 'rm' command from user2 of the same group GroupA, it doesn't allow as user2 is not the owner of the file. can setgid (at directory level) or other command help me to sort this issue?

  • Read part of a file in PHP

    - by Johan
    I would like to read the last 1 megabyte of a MP3 file and calculate SHA1 checksum for just that part of the file. The reason that I would want this is that when I'm looking for duplicate MP3's, the header info (song title, album etc.) can differ even though it's the exakt same audio file, so I figured I would be better of to checksum a part of the file at the end instead of the whole one. Is there an efficient way of doing this?

  • Wierd Windows File Share Behavior

    - by CT
    Scratching my head awhile on this. I'm on a Vista client trying to access a file share running on a Windows Server 2008 R2 box. Windows Active Directory Domain. The shares I am trying to access: \\Server1\FileShare1\Folder1\foo and \\Server1\FileShare1\Folder1\bar The client does not have any permissions at Folder1. The client has read permissions at folders foo and bar. In this example I can access \Server1\FileShare1\Folder1\foo but I get the following error when I try to access \Server1\FileShare1\Folder1\bar: "Network Error: Windows cannot access \Server1\FileShare1\Folder1\bar. Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose" I hit Diagnose. It returns with "Windows checked the path and '\Server1\FileShare1' is correct but 'Folder1' could not be found." What is going on? It finds Folder1 fine when going to \Server1\FileShare1\Folder1\foo.

  • Multicast File copy with Unicast responses

    - by kirbuchi
    I'm trying to do some multicast big file copies over to remote clients on the other side of a satellite link. The idea is to minimize the amount of traffic going up to the satellite. I tried using uftp without luck. The problem is that, even though we can reach clients via multicast from our central Hub, they aren't able to respond to a multicast address (it's not supported by the return link). As uftp needs to respond to a multicast address in order to report any missing packets I'm out of luck. So does anyone have any recommendations or alternatives I can use to do the trasfers? Any tip or pointer would be appreciated.

  • IIS wont run a BAT File

    - by Ye Ol Developer
    The problem we have run into is as follows. We have an ASP.NET WebService which runs under IIS7. The code in the WebService works 100%, however when the WebService tries to run a .BAT file, nothing happens. Nothing at all, the code doesn't crash, the server doesn't warn us about anything, nothing at all. We have tried setting the User Permissions, we have attempted difference ways of running the BAT, we have tried playing around with the registry, cmd.exe has full rights as well. We are now quite stumped as of what to do, any help would be appreciated.
