  • ftp 7.5 windows server 2008 I can not upload files

    - by rtwPhoenix
    I am using FTP 7.5 created virtual directory, gave user write permission under FTP for that directory. User logs in fine see everything however user can not upload any files. Keeps saying user does not have permission but they do in FTP. I have tried everything I know inclduing giving user permission on the directory itself. ISA 2006 in front of server I unchekced the READ box so I think that is OK (Publishing Rule) ANY HELP WOULD BE APPRECIATED. RTW

  • Transfer files between VPC and Host Machine.

    - by gwc
    I have a virtual machine setup and I am able to transfer files from the host to the vpc and from the vpc to the host. I then copied the vpc to another machine and I am not able to copy files anymore. How can you setup the ability to copy files between the VPC and the host machine.

  • Mac OS on a Windows PC

    I've done a little bit of reading on the topic, but nothing too clear has turned up. Why is it so difficult to run Mac OS on a virtual machine on a PC? Some sources say it's because of hardware architecture. Is there a clear, definitive reason?

  • Troubleshooting latency spikes on ESXi NFS datastores

    - by exo_cw
    I'm experiencing fsync latencies of around five seconds on NFS datastores in ESXi, triggered by certain VMs. I suspect this might be caused by VMs using NCQ/TCQ, as this does not happen with virtual IDE drives. This can be reproduced using fsync-tester (by Ted Ts'o) and ioping. For example using a Grml live system with a 8GB disk: Linux 2.6.33-grml64: root@dynip211 /mnt/sda # ./fsync-tester fsync time: 5.0391 fsync time: 5.0438 fsync time: 5.0300 fsync time: 0.0231 fsync time: 0.0243 fsync time: 5.0382 fsync time: 5.0400 [... goes on like this ...] That is 5 seconds, not milliseconds. This is even creating IO-latencies on a different VM running on the same host and datastore: root@grml /mnt/sda/ioping-0.5 # ./ioping -i 0.3 -p 20 . 4096 bytes from . (reiserfs /dev/sda): request=1 time=7.2 ms 4096 bytes from . (reiserfs /dev/sda): request=2 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=3 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=4 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=5 time=4809.0 ms 4096 bytes from . (reiserfs /dev/sda): request=6 time=1.0 ms 4096 bytes from . (reiserfs /dev/sda): request=7 time=1.2 ms 4096 bytes from . (reiserfs /dev/sda): request=8 time=1.1 ms 4096 bytes from . (reiserfs /dev/sda): request=9 time=1.3 ms 4096 bytes from . (reiserfs /dev/sda): request=10 time=1.2 ms 4096 bytes from . (reiserfs /dev/sda): request=11 time=1.0 ms 4096 bytes from . (reiserfs /dev/sda): request=12 time=4950.0 ms When I move the first VM to local storage it looks perfectly normal: root@dynip211 /mnt/sda # ./fsync-tester fsync time: 0.0191 fsync time: 0.0201 fsync time: 0.0203 fsync time: 0.0206 fsync time: 0.0192 fsync time: 0.0231 fsync time: 0.0201 [... tried that for one hour: no spike ...] Things I've tried that made no difference: Tested several ESXi Builds: 381591, 348481, 260247 Tested on different hardware, different Intel and AMD boxes Tested with different NFS servers, all show the same behavior: OpenIndiana b147 (ZFS sync always or disabled: no difference) OpenIndiana b148 (ZFS sync always or disabled: no difference) Linux 2.6.32 (sync or async: no difference) It makes no difference if the NFS server is on the same machine (as a virtual storage appliance) or on a different host Guest OS tested, showing problems: Windows 7 64 Bit (using CrystalDiskMark, latency spikes happen mostly during preparing phase) Linux 2.6.32 (fsync-tester + ioping) Linux 2.6.38 (fsync-tester + ioping) I could not reproduce this problem on Linux 2.6.18 VMs. Another workaround is to use virtual IDE disks (vs SCSI/SAS), but that is limiting performance and the number of drives per VM. Update 2011-06-30: The latency spikes seem to happen more often if the application writes in multiple small blocks before fsync. For example fsync-tester does this (strace output): pwrite(3, "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 1048576, 0) = 1048576 fsync(3) = 0 ioping does this while preparing the file: [lots of pwrites] pwrite(3, "********************************"..., 4096, 1036288) = 4096 pwrite(3, "********************************"..., 4096, 1040384) = 4096 pwrite(3, "********************************"..., 4096, 1044480) = 4096 fsync(3) = 0 The setup phase of ioping almost always hangs, while fsync-tester sometimes works fine. Is someone capable of updating fsync-tester to write multiple small blocks? My C skills suck ;) Update 2011-07-02: This problem does not occur with iSCSI. I tried this with the OpenIndiana COMSTAR iSCSI server. But iSCSI does not give you easy access to the VMDK files so you can move them between hosts with snapshots and rsync. Update 2011-07-06: This is part of a wireshark capture, captured by a third VM on the same vSwitch. This all happens on the same host, no physical network involved. I've started ioping around time 20. There were no packets sent until the five second delay was over: No. Time Source Destination Protocol Info 1082 16.164096 192.168.250.10 192.168.250.20 NFS V3 WRITE Call (Reply In 1085), FH:0x3eb56466 Offset:0 Len:84 FILE_SYNC 1083 16.164112 192.168.250.10 192.168.250.20 NFS V3 WRITE Call (Reply In 1086), FH:0x3eb56f66 Offset:0 Len:84 FILE_SYNC 1084 16.166060 192.168.250.20 192.168.250.10 TCP nfs > iclcnet-locate [ACK] Seq=445 Ack=1057 Win=32806 Len=0 TSV=432016 TSER=769110 1085 16.167678 192.168.250.20 192.168.250.10 NFS V3 WRITE Reply (Call In 1082) Len:84 FILE_SYNC 1086 16.168280 192.168.250.20 192.168.250.10 NFS V3 WRITE Reply (Call In 1083) Len:84 FILE_SYNC 1087 16.168417 192.168.250.10 192.168.250.20 TCP iclcnet-locate > nfs [ACK] Seq=1057 Ack=773 Win=4163 Len=0 TSV=769110 TSER=432016 1088 23.163028 192.168.250.10 192.168.250.20 NFS V3 GETATTR Call (Reply In 1089), FH:0x0bb04963 1089 23.164541 192.168.250.20 192.168.250.10 NFS V3 GETATTR Reply (Call In 1088) Directory mode:0777 uid:0 gid:0 1090 23.274252 192.168.250.10 192.168.250.20 TCP iclcnet-locate > nfs [ACK] Seq=1185 Ack=889 Win=4163 Len=0 TSV=769821 TSER=432716 1091 24.924188 192.168.250.10 192.168.250.20 RPC Continuation 1092 24.924210 192.168.250.10 192.168.250.20 RPC Continuation 1093 24.924216 192.168.250.10 192.168.250.20 RPC Continuation 1094 24.924225 192.168.250.10 192.168.250.20 RPC Continuation 1095 24.924555 192.168.250.20 192.168.250.10 TCP nfs > iclcnet_svinfo [ACK] Seq=6893 Ack=1118613 Win=32625 Len=0 TSV=432892 TSER=769986 1096 24.924626 192.168.250.10 192.168.250.20 RPC Continuation 1097 24.924635 192.168.250.10 192.168.250.20 RPC Continuation 1098 24.924643 192.168.250.10 192.168.250.20 RPC Continuation 1099 24.924649 192.168.250.10 192.168.250.20 RPC Continuation 1100 24.924653 192.168.250.10 192.168.250.20 RPC Continuation 2nd Update 2011-07-06: There seems to be some influence from TCP window sizes. I was not able to reproduce this problem using FreeNAS (based on FreeBSD) as a NFS server. The wireshark captures showed TCP window updates to 29127 bytes in regular intervals. I did not see them with OpenIndiana, which uses larger window sizes by default. I can no longer reproduce this problem if I set the following options in OpenIndiana and restart the NFS server: ndd -set /dev/tcp tcp_recv_hiwat 8192 # default is 128000 ndd -set /dev/tcp tcp_max_buf 1048575 # default is 1048576 But this kills performance: Writing from /dev/zero to a file with dd_rescue goes from 170MB/s to 80MB/s. Update 2011-07-07: I've uploaded this tcpdump capture (can be analyzed with wireshark). In this case 192.168.250.2 is the NFS server (OpenIndiana b148) and 192.168.250.10 is the ESXi host. Things I've tested during this capture: Started "ioping -w 5 -i 0.2 ." at time 30, 5 second hang in setup, completed at time 40. Started "ioping -w 5 -i 0.2 ." at time 60, 5 second hang in setup, completed at time 70. Started "fsync-tester" at time 90, with the following output, stopped at time 120: fsync time: 0.0248 fsync time: 5.0197 fsync time: 5.0287 fsync time: 5.0242 fsync time: 5.0225 fsync time: 0.0209 2nd Update 2011-07-07: Tested another NFS server VM, this time NexentaStor 3.0.5 community edition: Shows the same problems. Update 2011-07-31: I can also reproduce this problem on the new ESXi build 4.1.0.433742.

  • Apache Forbidden: httpd.conf or File Permissions

    - by Alan Storm
    When setting up an Apache virtual host, I'll occasionally get the following error when attempting to access the site. Forbidden You don't have permission to access / on this server. Is there any method to (or tool that will) tell me why Apache is denying access? (local rule in httpd.conf, file permissions, etc. I'm not looking for help with a specific configuration, instead I'm looking for a way to have the computer tell me what's wrong with my system and/or configuration.

  • DBRD dual primary Heartbeat resource management

    - by Jon Skarpeteig
    I have the following setup: Two servers with DRBD running dual primary with OCFS2 Heartbeat with two virtual ips, one for each server Round robin DNS to load balance NFS across the two vIPs Shutting down Server1 for a period of time, cause Server2 to take over the vIP for failover. However, when Server1 returns - it takes over the designated vIP as soon as heartbeat gets connection again - even though the DRBD is running sync (and thus not up to date) How can I configure heartbeat to perform failback as soon as Server1 again is in sync with Server2 ? (And not before)

  • Why does my MacBook Pro trackpad sometimes set its tracking speed to slow, all by itself?

    - by Paul D. Waite
    Every now and then, the trackpad on my MacBook Pro will seem to set its own tracking speed to slow. I’ll notice that the cursor is moving slowly, and when I check in System Preferences, the tracking speed is indeed at slow, even though I never set it to slow myself. This might happen before/after switching into a VMWare virtual machine, but I’m not sure. It doesn’t seem to happen on startup or anything, just during use. Anyone else seen this?

  • Is there a good command-line OS from which I can launch VMs?

    - by Dredj
    Generally speaking, I'm interested in something that can load quickly and, depending on what I want to do, can choose to launch a Virtual Machine that is tailored to my desired activity. So, something that loads to (preferably) a command line, then if I want to run my Windows 7 machine that has all of my programming junk on it, I can simply enter the command to launch some VM player and close it when I'm done.

  • MSTSC RDP over the public internet

    - by stuart Brand
    My first question so please be gentle :) I have a client who is insisting that they have to let their third party vendor support access to there server directly from the internet via RDP. Our policy does not allow direct access to the infrastructure from outside of the data centre for administration except from an approved VPN connection and then virtual desktop there on to the servers. I am now in the situation where I must give good reasons why it is dangerous to use RDP over the public internet. any help would be appreciated Thanks in advance Stuart

  • Apt pin and self hosted apt repo

    We have our own apt/deb repository with a handful of packages where we want to control the version. Crucially this includes puppet, which can be sensitive to versions being different.

  • Experiences with hosted (off-site) Microsoft Dynamics CRM?

    - by Beau
    We're currently testing Microsoft Dynamics CRM hosted by Fpweb. I've been asked by the lead on the project how we can increase the speed at which CRM pages in IE load. The delay seems reasonable to me for a virtual server located across the country. Has anyone succeeded in speeding things up with aggressive caching (i.e. a WAN accelerator) or by some other means? Do your employees complain about the speed of hosted Dynamics CRM?

  • Cloud computing?

    - by Shawn H
    I'm an analyst and intermediate programmer working for a consulting company. Sometimes we are doing some intensive computing in Excel which can be frustrating because we have slow computers. My company does not have enough money to buy everyone new computers right now. Is there a cloud computing service that allows me to login to a high performance virtual computer from remote desktop? We are not that technical so preferrably the computer is running Windows and I can run Excel and other applications from this computer. Thanks

  • use networkmanager without system tray

    I use the minimal "fast lightweight window manager" (fwlm) which doesn't have a system tray. I need a simple program to manage my WIFI and virtual private netwok connection --- and found the NetworkManager. The problem is that the NetworkManager is a system-tray icon: I cannot see it or click on it in my fwlm windows manager. Hence, I ask: Is there any way to start the NetworkManager directly without using the system tray?

    Hi, 1) Is there a way for me to install VirtualBox as a non root user? I compiled it from the sources but cannot find a way to load the kernel modules it requires? Is there anyway to make it run? 2) Is there any other virtualization software you have ever installed on linux successfully as a non root user, VMWare, Parallels, etc.? The aim is to run Windows as a virtual machine with more than 16GB RAM. Bests, Cetin

  • Recording screen-casts on another computer

    - by paleozogt
    We're trying to record the desktops of users using demo versions of our software (this is an in-house lab setup). We need to have the recording happen on a separate computer (just across the room), so that the recording software doesn't interfere with the user. Every screen recording software I've seen will only record what's happening on the computer its installed on; ie, you can't record what's happening on another computer. So it seems I need to cobble together a solution (unless anyone knows of software that will do this). Getting the video to the other computer seems easy enough. I'm using TightVNC with the DFMirage driver on the test computer. The recording computer connects to the test computer with TightVNC and then uses CamStudio to record what's happening. The real problem is how to deal with the audio. We need to record both what the user is saying (through a headset mic) as well as the sounds produced by the test computer. But VNC doesn't transmit audio. :( I'm not sure how to get both audio streams (mic and sounds) over to the recording computer. Any ideas?
