  • Can MS Services for Unix be deployed and accessed from a shared drive?

    - by Ian C.
    I'm interested in experimenting with replacing our dependency on MKS with MS' Sevices for Unix toolset. I was wondering if anyone has any experience with deploying SFU on a shared drive? We like to, wherever possible, host our dev tools on one central NAS and call to the NAS to access the tools instead of rolling stuff out to each and every desktop. I'm not interested in the NFS support or ActiveState Perl. Really, none of the daemon technology is required here. I'm looking for replacements for the coreutils/binutils stuff you find in Linux (and MKS on Windows): sed, awk, csh, bash, grep, ls, find -- the meat-and-potates command line apps that our build and test scripts are built around. If I limit the install to just the Interix GNU Components (and maybe the Remote Connectivity components) will is run nicely from a shared location? To head off some questions: Yes, I've looked at Cygwin. Unfortunately it's performance in our build and test environment is poor. It runs considerably slower than MKS and it's not a direct drop-in replacement for MKS (thanks to its internal pathing and limitations with commands like 'ps'), so it's a tougher sell. Yes, I'm looking at the MinGW offering in parallel to this.

  • LVM and cloning HDs

    - by jcea
    Using Linux, I have several backup levels. One of them is a periodical sector by sector copy (using dd) of my laptop harddisk to an external USB disk. Yes, I have other backups too, like remote rsync. This approach (the disk dd) is OK when cloning a HDD with no LVM volumes, since I can plug the external disk anytime and mount the partitions simply mounting /dev/sdb* instead of /dev/sda*. Trivial and handy. Today I moved ALL my harddisk (including the /boot) to LVM. Everything works fine. I will stress it for a couple of days, and then I will do a sector by sector copy to my external harddisk. Now I have a problem, I guess. If in the future I plug the external USB HDD to recover any file, the OS will detect a duplicate LVM configuration, with the same name and the same UUID. Even doing a vgrename (which LVM would be renamed, the internal HDD or the external HDD?), the cloned UUID will not change. Is there any command to change name and UUID? Ideally I would clone the HDD and then change the LVM group name and its UUID, but I don't know how to do it. Another related issue would be... In the past I have booted my laptop using the external disk, using the BIOS boot menu and changing GRUB entries manually to boot from /dev/sdb instead of /dev/sda. But now my current GRUB configuration boots directly from a LVM logical volume, something like: set root='(LVM-root)' in my grub.cfg. So... What is going to happen with duplicated volumes? Any suggestion? I guess I could repartition my external harddisk and change backup strategy from dd to rsync, but this disk has windows installed too, and I really would like to have a physical "real" copy.

  • port forwarding with socks over proxy

    - by Oz123
    I am trying to browse a wiki that runs on a server inside one domain from another domain. The wiki is accessible only on the LAN, but I need to browse it from another LAN to which I connect with an SSH tunnel ... Here is my setup and the steps I did so far: ~.ssh/confing on wikihost: Host gateway User kisteuser Port 443 Hostname gateway.companydomain.com ProxyCommand /home/myuser/bin/ssh-https-tunnel %h %p # ssh-https-tunnel: # http://ttcplinux.sourceforge.net/tools/stunnel Protocol 2 IdentityFile ~/.ssh/key_dsa LocalForward 11069 localhost:11069 Host server1 User kisteuser Hostname localhost Port 11069 LocalForward 8022 server1:22 LocalForward 17001 server1:7100 LocalForward 8080 www-proxy:3128 RemoteForward 11069 localhost:22 from wikihost myuser@wikihost: ssh -XC -t gateway.companydomain.com ssh -L11069:localhost:22 server1 on another terminal: ssh gateway.companydomain.com Now, on my companydomain I would like to start firefox and browse the wiki on wikihost. I did: [email protected] ~ $ ssh gateway Have a lot of fun... kisteuser@gateway ~ $ ssh -D 8383 localhost user@localhost's password: user@wikiserver:~> My .ssh/config on that side looks like that: host server1 localforward 11069 localhost:11069 host localhost user myuser port 11069 host wikiserver forwardagent yes user myuser port 11069 hostname localhost Now, I started firefox on the server called gateway, and edited the proxy settings to use SOCKSv5, specifying that the proxy should be gateway and use the port 8383... kisteuser@gateway ~ $ LANG=C firefox -P --no-remote And, now I get the following error popping in the Terminal of wikiserver: myuser@wikiserver:~> channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused Confused? Me too ... Please help me understand how to properly build the tunnels and browse the wiki over SOCKS protocol. update: I managed to browse the wiki on wikiserver with the following changes: host wikiserver forwardagent yes user myuser port 11069 hostname localhost localforward 8339 localhost:8443 Now when I ssh gateway I launch Firefox and go to localhost:8339 and I hit the start page of the wiki, which is served on Port 8443. Now I ask myself is SOCKS really needed? Can someone elaborate on that ?

  • Scroll wheel causes browsers + Windows explorer to go back

    - by KaptajnKold
    I use Windows 7 on a VirtualBox VM on a Mac. Lately, when I'm using any browser (IE9, Chrome or FireFox or even Windows Explorer), use of the scroll wheel followed by any movement of the mouse cursor causes the browser to go back. Very annoying. This happens when I use the scroll wheel on a USB connected mouse (brand/model unknown, since I don't have it in front of me as I write this) or when I use two-finger scrolling on the trackpad when no mouse is connected. When I connect from my VM to a remote Windows box (Windows Server 2008), I experience the same problem. I have tried rebooting the VM to no avail. I am not sure when the problem started exactly. It may or may not have been after I connected the USB mouse for the first time, but trying to unplug it and then rebooting didn't help. I have tried to google for a solution, but all I've found are people who accidentally pressed the shift key while scrolling, which will cause the browser to go backward or forward in the browser history. This however is not the problem I'm having. To be clear, in my case the browser only goes back when I move the mouse after I've used the scroll wheel. I'm at my wits end :(

  • XP SP2 Event log not logging events

    - by Weedfreer
    I have a problem whereby a terminal appears not to be logging events correctly and occasionally appears to have problems communicating accross the network.The terminal has previously been infected with a virus which apears to have 'played' with the default group policy in the standard user profile. Although, outwardly, the terminal appears to be working normally I still have a nagging feeling that it isn't quite back to the way it was. It was infected by a user plugging in a USB Stick while the company was using the older version of the AV software...typically a week or so before it was updated.I have configured the Event logs to Overwrite as required and to be 5056KB in Maximum size. I have also attempted:- Disabling the Event Log service & restarting Renewing the EVT files in Windows\system32\config directory Restarting the event log service and restarting Clearing the event log in the Services MMC Resetting the Filters to Default in the services MMC Using the EVENTCREATE command remotely from a CMD window on the server to force an event creation event. So far the only operation to have any sort of success is the remote computer EVENTCREATE command from a CMD window on the server. As it stands, the only other time that the computer has managed to create events is while it is being restarted.Has anyone gotany ideas on how to proceed? I'm thinking that possibly a refresh of the 'Windows\system32\config\SystemProfile' folder. I'm also thinking about running a tool such as Malwarebytes but this could be slightly controvertial as the system needs to be running on 'up-time' for as long as possible. I'm also wonderign whether anyone knows of any Windows admin tools that allow me to control the event logging options or default security options so that i could get it back to some sort of standard.What I'm trying to avoid is a complte re-imaging of the terminal. Although this is an option, I dont really want to have to take it if i dont need to.Many thanks in advance for any suggestions anyone may be able to provide.

  • Wake OSX 10.8 over WiFi (WoWL - Wake on WiFi Lan)

    - by WrinkledCheese
    I have a stack of Apple Mac minis running SSH servers for remote login. The problem is that I can't seem to get them to wake up. From what I gathered, as of Mac OSX 10.7 you required to have a boot time option set - darkwake=0 10.7 and darkwake=no 10.8. So I tried this and then I came to the realization that this will probably work for a wired connection but I'm using WiFi. My wired connections are used for another local subnet without Internet access, so I have to get it to wake on WiFi. I realize that I can just set the stack of Mac minis to just not sleep, but I'm looking for a sleep enabled option. These services don't require initial response speed as once the connection is made they will be active and once they are no longer active they will hopefully go back to sleep. I have a FreeBSD box running avahi-daemon in order to try and wake the Macs with the Bonjour Service but it doesn't seem to work. I tried registering the service as Gordon suggested in the below post, but that just makes it so that there isn't a timeout when discovering services and resolving them. It still doesn't allow ssh connections to port 22 when it's asleep. For reference, I want what seems like what Gordon Davisson explained on this question: Wake on Demand for Apache server in OS X 10.8

  • Cannot browse ipv4 websites (OpenVPN )

    - by user1494428
    I have set up an openVPN tunnel on my VPS (OpenVZ - Ubuntu 12.04). The problem is when I'm connected to the vpn, I can only browse websites which support ipv6 like google. Ipv4 sites aren't loading (no error, just waiting indefinitely). http://whatismyv6.com/ reports me that I've an ipv6 address, so I guess this is the problem. Server configuration: dev tun server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt ca /etc/openvpn/easy-rsa/keys/ca.crt cert /etc/openvpn/easy-rsa/keys/server.crt key /etc/openvpn/easy-rsa/keys/server.key dh /etc/openvpn/easy-rsa/keys/dh1024.pem push "route 10.8.0.0 255.255.255.0" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" push "redirect-gateway def1" comp-lzo persist-tun persist-key status openvpn-status.log log /var/log/openvpn.log verb 3 Client configuration: client remote xx.xx.xx.xx 1194 dev tun comp-lzo ca ca.crt cert client1.crt key client1.key redirect-gateway def1 verb 3 I have configured NAT with this command: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to xx.xx.xx.xx Can someone explain me how I can make it works (forcing ipv4?) I had the same problem with another vps and I also tried on another client (All Windows 7).

  • Multiple static WAN IP addresses to single LAN subnet

    - by Jessy Houle
    Below is my home network topology. I currently have 5 static IP addresses, 3 of which are in use by 3 routers. These routers in-turn subnet internal networks and port forward. I use my SSL VPN appliance to remote home from work or on the road. At this point I can remotely administer my Windows Server. I know the network is setup wrong, I was matching existing hardware the best I knew how. http://storage.jessyhoule.com.s3.amazonaws.com/network_topology.jpg Ok this said, here is the problem... One of my websites on my Windows Server now needs to be secure (SSL using port 443). However, I'm already port forwarding port 443 to my VPN appliance. Furthermore, if I'm going to have to reconfigure the network, I would really like to be able to use the SSL VPN to remotely administer all machines. I mentioned this to a friend of mine, who said that what I was looking for was a firewall. Explaining that a firewall would take in multiple static (WAN) IP addresses, and still allow all internal devices to be on the same network. So, basically, I could supply my SSL VPN appliance it's very own static (WAN) IP address routing, and yet have it on the same internal network (192.168.1.x) as all my other devices. The first question is... Does this sound right? Secondly, would you suggest anything different? And, finally, what is the cheapest way to do this? I am started down the road of downloading/installing untangle and smoothwall to see if they will do the job, hoping they take multiple static (WAN) IP addresses. Thank you in advance for your answers. -Jessy Houle

  • Cannot Access Shared Folder From IIS

    - by Tim Scott
    From IIS I need to access a folder on another computer. Both servers are Window 2008 SP2, and they live in a Virtual Private Cloud on Amazon EC2. They reach one another by private IP -- they are in WORKGROUP, not a domain. I can access the shared folder manually when logged in to the client as Administrator. But IIS gets "access denied." Here's what I have done: Set File Sharing = ON Set Password Protected Sharing = OFF Set Public Folder Sharing = ON Shared the folder Added permission to the share: Everyone, Full Control Added permission to the share: NETWORK SERVICE, Full Control Verified that File & Printer Sharing is checked in Windows Firewall Opened port 445 to inbound traffic from local sources I tried adding <remote-machine-name>\NETWORK SERVICE to the share but it says it does not recognize the machine, which makes sense, I guess. As I said, from the other computer I have no trouble accessing the shared folder from my user account, but IIS is shut out. How does the file server even know the difference? I would assume that with Everyone given full control and password protected sharing turned off, it would not matter what the client user account is. In any case, how to solve? UPDATE: To clarify, I am not trying to serve up files on the share directly through IIS. Rather I am writing files to the share from my code (System.IO).

  • Sharepoint (WSS 3.0) on SBS 2008 broken.

    - by tcv
    I recently ran the Sharepoint Products and Technologies Wizard. I had hoped this would bring up Sharepoint and allow me to access it so I could begin to learn. But it's not working. Here is some data that I hope is relevant. I am doing all my testing on the SBS 2008 server itself. I changed the hostheader in IIS to reflect an external FQDN I plan to deploy. The SBS server is remote and there are no domain-connected workstations. If I browse "localhost" SSL, I can get to the site, albeit with a self-signed cert warning. If I attempt to connect via SSL using either the internal FQDN (.local), the External FQDN (.net) or any other permutation thereof, I am prompted for credentials three times but am not allowed access. My account is a domain admin. The site is inaccessible using port 80 whether using localhost, internal FQDN (.local), and external FQDN (.net) Right now, I suspect my problem is within IIS, but I don't know. My plan to publish the sharepoint site to the web so my partner and I can check documents in/out. Can someone help me get started in current direction?

  • Ubuntu karmic, chroot, Ubuntu server 8.04 LTS and Plesk

    - by morpheous
    I am pretty new to the Linux environment, and although I have been using Ubuntu Karmic desktop for development work, I have always prefered the GUI tools and very rarely use the terminal. I am about to launch a site (a VPS) which will be running Ubuntu server 8.04 LTS and Plesk. I want to install both the server (8.04 LTS) and Plesk in a 'chroot' on my Karmic desktop. I also want to test install some packages I have written for the server, and generally familiarize myself with the environment before I signup to the hosting service. I will be running a streamline server (no GUI), with only the following software: PHP Python mySQL PostgreSQL Apache Plesk Third party packages I developed In terms of mail, I think the hosting provider provides a mail service, so I dont know if I will need to run my own mail server. I will like some advice on the following: How can I install Ubuntu 8.0.4 server LTS in a chroot? How can I install Plesk in Ubuntu 8.0.4 server LTS (from the command line) Can anyone recommend how I back up the remote server when I go live (i.e. what tools to use)?. I will need to back up both databases, as well as some config data and installation packages

  • WSS Search fills 10 GB limit on SBS server 2011

    - by Kactus
    I've got a SBS Server 2011 Standard SP1 that isn't very busy. 2 Users local and 2 remote. We have sharepoint that has maybe a dozen small documents at most. I've just started getting the following two error occur Could not allocate space for object 'dbo.MSSBatchHistory'.'IX_MSSBatchHistory' in database 'WSS_Search_SERVER' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. And CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 10240 MB per database. Digging around in SQL manager I see that WSS Search DB file size is 10241MB, the log file is only 147 MB Firstly, why is WSS Search taking up so much space? How can I stop it from doing so, and what can I do now to get things running ok. I know about log file truncating and this isn't the case here since the log is tiny. Any help is appreciated. There is plenty of free space on the disk (791GB free) Thanks Kactus

  • Is timeout in tracertoutput an indication of an error?

    - by nitramk
    TCP/IP packages sent from my computer to a remote server does not always reach destination and ends up being retransmitted sometimes several times before they succeed. To troubleshoot this, I'm running a tracert to the server: Tracing route to <site> [<address>] Over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms mymachine 2 <1 ms <1 ms <1 ms gw.levonline.com [217.70.32.30] 3 <1 ms <1 ms <1 ms 81.201.213.218 4 <1 ms <1 ms <1 ms bmf1-hmf1.driften.net [81.201.213.12] 5 <1 ms <1 ms <1 ms 10ge-2-4-cr2.a1.sth.ownit.se [84.246.88.157] 6 <1 ms * <1 ms netnod-ix-ge-b-sth-4470.microsoft.com [195.69.11.181] 7 26 ms * * ge-3-0-0-0.ams-64cb-1a.ntwk.msn.net [207.46.42.1] 8 48 ms 57 ms 56 ms ten9-1.lts-76e-1.ntwk.msn.net [207.46.42.133] 9 * * * Request timed out. In step 6 and 7, I'm seeing timeouts while waiting for the reply from the server (as seen above). Running the same tracert many times gives varying output, sometimes the response is fine, but sometimes I get this timeout 1, 2 and sometimes for all 3 packets. The timeout always starts at the same server, netnod-ix-ge-b-sth-4470.microsoft.com. I've tried setting the tracert timeout to 10 seconds, but am still getting the timeout. Running tracert towards other servers does not give me the same timeout. Microsoft network technicians tells me that the problem is not on "their" side. Are these timeouts an indicator of a lost packet on the specific node which did not respond? Are the timeouts an indication of there being a problem, or is it normal?

  • OpenVPN Server - CPU is pegged out

    - by ericl42
    Hello, I am configuring OpenVPN to act as a SSL tunnel for a remote location. I have OpenVPN1 at our current location acting as a server then OpenVPN2 at the other location that is acting as a client but is also acting as a DHCP server to machines behind it so they are basically connected to the local LAN. Everything is set up fine and I can talk from location A to location B with no problems like everyone is local. I am however having some performance issues. OpenVPN1 CPU is pegged to 100% the entire time I am copying or doing any type of activity through the tunnel. I expect some CPU usage going up but nothing like this. It's really killing my performance. OpenVPN1 is running in ESX right now with 2 gig RAM and 4 procs with unlimited bursting capacity. I am using AES-192 encryption with a 1024 key. Any idea how I can get my CPU down on OpenVPN1 and my download/upload speeds higher between the tunnel? Thanks. edit: Turning down the logging helped boost the throughput a little bit, but I am still fairly shy of where I believe I should be. Also I am still maxed out on the CPU. Does anyone have any ideas? I am really stuck on this. Thanks.

  • VPN Client solution

    - by realtek
    I have several VPN's that I need to establish on a daily basis but from multiple workstations. What I would like to do it have either a server or vpn router that can perform this connection itself and that I can then route traffic through this device or server depending on the subnet I am trying to reach. The issue is that I only use VPN Clients to connect, so I am basically trying to achieve almost a site to site VPN but by using basically a VPN Client type connection from my network. The main VPN Client I use is the Sonicwall Global VPN Client where I initially use a Preshared Key and then it always prompts me for a username and password (not RSA key). My question is, is there any type of linux distro or even a hardware vpn router that can do this and connect to a Sonicwall device as if it were a client? I have tried pfSense which is very good but it fails to connect, probably due to a mismatch of settings. I have tried many others. Even dd-wrt on my router but it does not support whatever protocol Sonicwall uses. (I thought L2TP/IPSec) but it appears it may not be that. Any advice would be great! The other other thing I have thought of that I have not tried yet is Windows Server Routing and Remote Access but I have a feeling that won't work either. Thanks

  • Network Load Balancing, intermittent port problem on Windows Server 2008

    - by Jimmy Chandra
    Trying to troubleshoot an intermittent problem on a Windows Server 2008 NLB. I think it might be related to an NLB issue. We are using Windows Network Load Balancing to balance load for our multiserver SharePoint front ends. Say... Web Front End 1 IP is 192.168.1.100 and Web Front End 2 IP is 192.168.1.101, the NLB is setup to load balance both WFE servers on any incoming traffic to the IP 192.168.1.200. Sometimes we got an intermittent issue where when we try to access the SharePoint site using 192.168.1.200:8080 (say the site is set up to run on port 8080) from a remote client, it will display page not found. Pinging the 192.168.1.200 will give responses, but when trying to telnet to 192.168.1.200:8080 it just won't connect. However, browsing the SharePoint site directly on individual WFE (192.168.1.100 and 192.168.1.101) show no problem whatsoever. My guess also (we didn't get a chance to try it yet, but I think it should work), if I try connecting remotely to individual server, it will respond just fine. But any attempt on trying to connect using the virtual IP (192.168.1.200) will fail miserably. Funny thing is, after a while it will return back to normal. Anyone had similar experience with this type of problem while implementing NLB before? We are doing this in a virtual environment.

  • Routing subnet over GRE tunnel

    - by eMgz
    Hi, Im trying to configure a GRE over IPSec connection between two subnets. The IPSec tunnel is opened and now I want to add a GRE tunnel over it: ip tunnel add GRE01 mode gre remote 10.244.0.1 local 10.244.245.32 ttl 255 ip link set GRE01 up ip addr add 10.244.248.126 dev GRE01 ip route add 10.244.248.125 dev GRE01 Now I have an interface GRE01 (ifconfig): GRE10 Link encap:UNSPEC HWaddr <h_addr> inet addr:10.244.248.126 P-t-P:10.244.248.126 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MTU:1476 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) And the following routes (ip route list): 10.244.248.125 dev GRE10 scope link <pub_subnet> dev eth0 proto kernel scope link src <pub_ip> default via <pub_gw> dev eth0 metric 100 As a last step, I need now to route my subnet over the tunnel: ip route add 10.245.1.224/28 10.244.248.125 However, I am getting the error Error: either "to" is duplicate, or "10.244.248.125" is a garbage. So, what I didn't understand is why I can't route my subnet over the tunnel, once the only route I have there says that it should route the tunnel IP over the GRE01 interface. Any hint? Thanks.

  • Pair programming with tmux and Vagrant

    - by neezer
    Does anyone have a clear step-by-step guide for setting up a shared tmux session on a Vagrant vbox that my coworkers (on our local office lan) could SSH into? The articles I've found online only seem to cover setting this up from machine to machine (no virtualbox setups), and I'm not very good at networking, so I haven't been able to extrapolate a solution... We're all running the latest Macs in our office, btw. Here's one article I've found but haven't been able to get working with Vagrant: http://blog.voxdolo.me/remote-pairing-with-vim-and-tmux.html EDIT: To clarify, I don't really know how I should be setting up Vagrant to allow me to SSH into it from a machine outside the one hosting the VM. The article above suggests that I add the tunnels host on my physical machine running the VM (here-on referred to as the MBP), so I did that. Next is the ProxyCommand host declaration, which I have also assumed should live on the MBP. So next I try SSHing into the MBP from a guest machine (another separate physical machine on my network), and that seems to work... but that only gets me into the MBP, not the Vagrant image running on the MBP. I normally login Vagrant image on the MBP via vagrant ssh (per the docs), and I know how to forward ports on the Vagrant VM to the MBP, but it's unclear to me how I could forward ports/SSH from the MBP to the Vagrant VM, which I assume I would need to do so that my guest machine could SSH in--through the MBP--to my Vagrant image. That, in a nutshell, is what I'm trying to accomplish. I do my development work in Vagrant VMs which keeps my MBP nice and clean of any dev-related cruft and also keeps my dev environments totally isolated from one another, yet I would like to start pair-programming with my coworkers via tmux, thus the reason why I've asked this question. I would like to accomplish all of this without setting up an additional user account on the MBP, or giving my coworkers access to my local user account on the MBP to get to my Vagrant VM, if that's at all possible.

  • How to allow writing to a mounted NFS partition

    - by Cerin
    How do you allow a specific user permission to write to an NFS partition? I've mounted an NFS share on my localhost (a Fedora install), and I can read and write as root, but I'm unable to write as the apache user, even though all the files and directories in the share on my localhost and remote host are owned by apache. For example, I've mounted it via this line in my /etc/fstab: remotehost:/data/media /data/media nfs _netdev,soft,intr,rw,bg 0 0 And both locations are owned by apache: [root@remotehost ~]# ls -la /data total 24 drwxr-xr-x. 6 root root 4096 Jan 6 2011 . dr-xr-xr-x. 28 root root 4096 Oct 31 2011 .. drwxr-xr-x 4 apache apache 4096 Jan 14 2011 media [root@localhost ~]# ls -la /data total 16 drwxr-xr-x 4 apache apache 4096 Dec 7 2011 . dr-xr-xr-x. 27 root root 4096 Jun 11 15:51 .. drwxrwxrwx 5 apache apache 4096 Jan 31 2011 media However, when I try and write as the apache user, I get a "Permission denied" error. [root@localhost ~]# sudo -u apache touch /data/media/test.txt' touch: cannot touch `/data/media/test.txt': Permission denied But of course it works fine as root. What am I doing wrong?

  • Is there a way to run CUDA applications with the CUDA device being a secondary adapter?

    - by Slartibartfast
    I've been trying to run a CUDA program on a remote computer which has Windows 7 installed. The GPU is GeForce GTX 480. One of the problems I've been facing is that, the computer has two adapters, 1) Standard VGA Adapter 2) NVIDIA GeForce GTX 480 Even though this shows in the device manager. The desktop uses the standard VGA Adapter. I'm assuming this is because the Standard VGA is the primary adapter. Also the device manager shows that the monitor is connected to the standard VGA Adapter. In this scenario if i try to run any CUDA application it fails to recognise a CUDA capable device. Is it necessary for the NVIDIA adapter to be the primary one? Or is there any way to use CUDA when the graphics card is a secondary adapter. I've seen a few posts in the NVIDIA forums on this before, one suggests using another low cost NVIDIA card as the primary adapter, but that is currently not an option. I couldn't find any other solutions. Thanks I tried running the deviceQuery test from the NVIDIA GPU Computing Samples. This was the result i obtained CUDA Device Query (Runtime API) version (CUDART static linking) cudaGetDeviceCount FAILED CUDA Driver and Runtime version may be mismatched FAILED The driver version I'm using is 263.06. The CUDA version is 3.2 I ran the same test on my desktop which also has windows 7 and a GeForce GTX 465. The CUDA toolkit version is 3.2. The driver version was the same and the test passed, although it failed with an older driver.

  • Cannot establish XMPP server-to-server connection with gmail

    - by v_2e
    My jabber-server fails to connect to gmail.com giving the error: outgoing s2s stream myserver.com.ua-bot.talk.google.com closed: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.) I am using the Prosody XMPP server. It works just fine with other jabber-servers I tested so far (e.g. jabber.ru). However, when some of my clients tries to add a gmail contact to his contact-list, the subscription request lasts forever, and the Prosody gives the following sequence of messages in its log: Oct 21 22:57:16 s2sout95897f8 info Beginning new connection attempt to gmail.com ([173.194.70.125]:5269) Oct 21 22:57:16 s2sout95897f8 info sent dialback key on outgoing s2s stream Oct 21 22:57:16 s2sout95897f8 info Session closed by remote with error: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.) Oct 21 22:57:16 s2sout95897f8 info outgoing s2s stream myserver.com.ua->gmail.com closed: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.) Oct 21 22:57:16 s2sout95897f8 info sending error replies for 2 queued stanzas because of failed outgoing connection to gmail.com Here for the domain name of my server I use myserver.com.ua I found a similar problem described in this thread, but there is no detailed description of the solution there. As for the Google services, I did have a google account where I added the domain name under question to the Webmasters tools page. However, I deleted my account long ago, so now it is unclear, how any of the Google services can relate to my domain name. So my question is: What is the real cause of this problem (my jabber-server configuration or imaginary Google account or something else) and how can I make my Prosody server connect to gmail.com jabber service?

  • Windows 2012 RDS Temporary profile for Administrator

    - by Fabio
    I've configured a Windows 2012 RDS Farm with two virtual servers (VMWare - each one on a different ESX server). Both servers have Licensing, Web Access, Gateway, Connection Broker and Session Host roles. High Availability is set up and it works fine. Remote Apps are working and even Windows XP clients have access to the web interface. User profile path is \vmfiles1\UserProfileDisks\App\ and almost everyone has full right access to it. The problem I have is that I would like to be able to access both servers at the same time with the Administrator account (console), but each time I try, the second server that I logon to give me access with a temporary profile. I tried to enable/disable multiple sessions per user and forced Admin logoff with the GPO but nothing changed. Another thing is that the server pool is not saved, so each time I restart the RDS server or I logoff from it, I have to add a server in the server manager. Do you have any idea? Sorry if my english is not perfect.

  • pppd disconnects from 3G, doesn't reconnect, w/ persist set

    - by bytenik
    I am trying to configure pppd to connect to a 3G network (Sprint, in this case) and then stay connected, reconnecting automatically if the remote connection is terminated. I have enabled the persist option. My configuration file is as follows: hide-password noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/cellular" debug /dev/cell 921600 defaultroute noipdefault user " " persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 60 holdoff 5 However, when the peer disconnects the connection, pppd often waits a long time (substantially more than my holdoff) to reconnect the modem -- if it ever reconnects at all! An example log showing this: May 23 05:17:24 00270e0a8888 pppd[2408]: rcvd [LCP TermReq id=0x26] May 23 05:17:24 00270e0a8888 pppd[2408]: LCP terminated by peer May 23 05:17:24 00270e0a8888 pppd[2408]: Connect time 60.1 minutes.

I had a friend monitoring the server so I'm not certain that this wasn't a manual reconnection. Either way, it either took almost an hour to reconnect or never reconnected. Shouldn't persist + holdoff 5 cause this to automatically reconnect after 5 seconds of the link terminating?

  • Unable to PPTP through NAT on Cisco 881

    - by MasterRoot24
    I'm trying to connect to a PPTP server which is sat behind a Cisco 881 NAT router. The server is running Ubuntu Server 12.04 and is running Poptop pptpd as the PPTP daemon listening for connections. As discussed in my other question, I'm trying to setup a Cisco 881 router to replace my old Linksys WAG320N. This same server and WAN connection worked fine with the WAG320N with no special configuration, other than allowing 1723 in through the firewall. On the Cisco 881, I'm using the newer ip nat enable or NAT NVI to setup static routes in through the firewall for the services running behind the router. My reason being that I can't run another copy of my live DNS domains internally with local IP addresses in. For the purposes of this question, though, I have rebuilt the router with ip nat inside/outside style NAT'ing, but this issue is still apparent. HTTP/SMTP/IMAP etc. all work ok from both the WAN and LAN interfaces of the router. I'm only having issues with SIP (see other question) and PPTP. My issue is that the GRE doesn't appear to be passing through NAT correctly and one end of the connection is not receiving GRE traffic when it should be, so the server hangs up the connection. Here's an example of /var/log/syslog with debug enabled in /etc/pptpd.conf: Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: MGR: Launching /usr/sbin/pptpctrl to handle client Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: local address = 192.168.1.50 Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: remote address = 192.168.1.51 Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: pppd options file = /etc/ppp/pptpd-options Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Client 82.132.248.216 control connection started Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Received PPTP Control Message (type: 1) Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Made a START CTRL CONN RPLY packet Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: I wrote 156 bytes to the client.

Trying the connection to the LAN IP of the server from the same LAN as the server (behind the router), the PPTP connection works fine, so I'm confident that the server's config is ok. Furthermore, all I needed on my WAG320N was to open 1723 in the firewall. Here's my current router config: ! !

When attempting a connection, I can see in show ip nat nvi translations that both a TCP translation on 1723 is setup and also a GRE translation is setup also. I appear to be able to see GRE related packets on the LAN that the server is on, so I am lead to believe that the server is sending(?) GRE packets, however running Wireshark on a client PC when attempting a connection shows absolutely no GRE packets. Whilst there are no configuration directives in my config posted above (that I can pin point) which would specifically block them, it would appear that the GRE packets are not being allowed in/out of the router's firewall, even though a NAT translation entry is setup to the server's LAN address. Would anyone be able to provide me with some help to ensure that GRE packets are not blocked by the router's firewall, so that this can be ruled out as a possible issue please?
