  • How to share internet over VPN and inside a virtual machine (Windows)?

    - by mountrix
    ` My final goal is to have a virtual machine at work in which anything that happen inside (tcp, udp, ping, ...) will use the Internet connection of a computer at home. So, if inside this VM should I open an Internet browser to a site such as "show my IP", my home IP should be printed. I am also looking for a way to debug/develop a software inside this VM, but I would like to tunnel only the connections of this software, not the full graphical interface, this is why a Remote Desktop solution won't fit me. The connection between the both computer should be secured somehow, like in a SSH tunnel. This ultimately should allow me to have a portable VM in which I can connect to whatever networks I have access at home, in a secure way. This is my configuration: At work, I have a LAN-connected desktop computer, with Windows 7 Professional Edition as a host [computer W] On this same computer, I have a Virtual Box machine running Windows XP [computer V] At home, I have a laptop computer, running Windows 7 Home Edition [computer H] This laptop is connected to a Livebox 2 broadband modem by Wifi. What I am trying to do is to sit at work in front of the virtual machine [V], and connect to a webpage as if the request was issued from the laptop [H] at home, and the data should be securely tunneled between the both. But if I am using internet directly inside [W], it should use the normal LAN interface at work. To achieve my goal, I first try using VPN, than SSH tunneling, without success. I first tried to install Teamviewer between [W] and [H]. This is working fine, I can send files, share desktop, etc. Teamviewer has a VPN mode that creates a new VPN network interface with its own IP, both on computer [W] and [H]. This allowed me to connect [H] as a network computer inside [W] and I was able to share files, but not to share Internet. At this point, I tried to use from [W] the Internet as if I was at home. I setup a route (using route add from command line in [W]) in order to instruct each packet going to a given website to pass by the new VPN interface on [W], with the hope it will be forwarded to [H], but the webpage was simply inaccessible. I then tried to setup a Windows VPN connection between [W] and [H], using the Windows 7 VPN feature. [H] was the server and [W] the client. But it failed: I got the "Unable to join a remote PC while trying to VPN" 720 Error when I was setting up the client on [W]. I think the problem is the Livebox 2 that could blocks the packets. But I am not sure of this: 1) with Teamviewer it works fine, 2) Livebox 2 has a configuration page for port mapping that gives the proper configuration to map VPN ports as an example so I guess that it should allow it, 3) I opened the ports 1723 (TCP) and 500 (UDP) according to some forums. Virtual box has a network configuration parameter in which I can use the VPN network interface created by Teamviewer as a bridged connection. This is suppose to work in the sense that all packets issued by the virtual machine [V] is supposed to go directly to [H]. But I had no internet connection inside [V]. Using the NAT mode, [V] has internet. For me this is the feature that I look for: filtering all connections from the virtual box application to the VPN network interface, and the remaining should use the normal LAN interface. Apart from the build-in feature of VBox, I even do not know if it is possible to route the packet from a given application to a given interface. Finally I tried also SSH tunneling, but this is not the solution I looked for. Using an external SSH server (Linux), I was able to create a localhost connection on [W] (or [V]), using something like 'ssh -N -D server[H]' in order to allow a web browser located in [W] to connect to any website using the SOCKS 5 proxy created locally (SOCKS is a build-in feature of SSH). But repeating the same operation on windows, using a windows SSH server inside [W] (I tried freeSSHd), it failed: SFTP worked, but not the SOCKS tunneling, it was like the browser in [H] did not find internet. Finally only Teamviewer looked able to create a VPN between [W] and [H], but I am not able to use it, as I want, I mean using the Internet connection of [H] sitting in front of [W]. I also tried to bridge the VPN interface and the wifi interface inside [H], but it blocked my laptop, and I tried also the Internet Connection Sharing, trying to share on [H] the wifi connection over the VPN interface. This fails also, but it seems because Teamviewer actually use the wifi interface to be able to provide the VPN link, so I guess I am creating a recursive loop. I do not know what to try next... Thank you for any advice!!

  • Is there a way to allow administrators to change or reset user passwords?

    - by Jon Seigel
    We have a custom MembershipProvider implementation using form-based authentication (FBA) under Sharepoint 2007. I've searched high and low on Google, but only found: Active directory and FBA implementations to allow users to change their own password Active directory instructions (including video!) for administrators to change other users' passwords Have we missed an option to enable the latter under FBA? Should this work by default and is the MembershipProvider misbehaving? The procedure to do this as under active directory would be ideal, but the "Change Password" link does not appear in the Edit User screen. We verified that the logged-in user is a site collection administrator.

  • How can I allow a linux subversion user to only execute svnserve?

    - by sbleon
    I've got a user that I'd like to only be able to use subversion. We like to use svn+ssh:// URLs sometimes (for public keys and whatnot), so I need them to be able to connect over ssh and run only the svnserve command. When using a svn+ssh URL, svn ssh'es in and passes the arguments "-c svnserve -t". I wrote a custom shell as follows to filter the commands that can be run. This works, but it's not passing the input to svnserve, so when I try to "svn up" I get "svn: Connection closed unexpectedly". #!/bin/bash if [ "$1" == "-c" ] && [ "$2" == "svnserve" ] && [ "$3" == "-t" ] && [ "$4" == ""] ; then exec svnserve -t else echo "Access denied. User may only run svnserve." fi

  • How can i get more user debug logging related to kerberos for alfresco?

    - by Maarten
    I am running alfresco community edition 3.4c on a debian linux. I have problems getting the kerberos authentication in order. The biggest problem is that do not seem to have any sort of user logs. what i am using already: log4j.logger.org.alfresco.web.app.servlet.KerberosAuthenticationFilter=debug log4j.logger.org.alfresco.repo.webdav.auth.KerberosAuthenticationFilter=debug log4j.logger.org.alfresco.smb.protocol=debug log4j.logger.org.alfresco.fileserver=debug I've also checked if the users actually reach the server, and they do, (also on a linux firefox outside of domain, i seem to be able to log in). Can anyone help me get more user logging?

  • A different interface for the Sql Server Reporting Service?

    - by AngryHacker
    I have a SQL Server 2005 SQL Reporting Services implementation. It seems that the only way to actually access the reports is for the users to use Internet Explorer. The web page uses an ActiveX control to do its printing (and probably other functions as well). Does SSRS have a different way to access its functionality via the web browser? Like maybe Java or HTML based? If so, how do I actually turn it on? The reason I am asking is because the security is being tightened and ActiveX controls will be banished, thus the users won't be able to print.

  • How to make ssh/rsync/etc use a VLAN network interface?

    - by Annan
    A company I work for has a number of virtual servers with ElasticHosts. They are setup in such a way that eth1 is on a private VLAN connecting them to each other. This is so backups sent between servers are not charged at the same rate as external data transfer. My understanding of how VLANs and network interfaces work is sketchy at best. How can I make ssh, rsync, etc. transfer data through the VLAN? My final solution: I spent a while trying to figure this out, For all servers involved, edit /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static ONBOOT=yes HWADDR=YOUR_MAC_ADDR IPADDR=192.168.0.100 NETMASK=255.255.255.0 Where HWADDR should already be set and the last octate of IPADDR should be different from each other. Then run, on all servers /etc/init.d/network restart After this the IP addresses specified by IPADDR can be used directly as any other IP address.

  • OWA (Outlook Web Access) won't give user a link to attached document. Gives "Open as Web Page"

    - by Jerry Mayers
    I have been testing OWA and have found that when there is an attached file on a message it shows the "Attachments:" then the file name (but no link) and then [Open as Web Page] link. The user has to click on that which opens a new window and previews the document, then the user gets "You are currently viewing:" followed by the file name. This time the file name is a link that they can open/download. This happens for Office documents and PDF file at least. How do I make it so users can get a direct link to the file on the original message window?

  • how to limit upload bandwidth per user in linux?

    - by Gihan Lasita
    Can anyone provide the tc command to limit upload bandwidth per user in Debian Lenny? I found that to mark packets per user with iptables I can use the following command iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner testuser -j MARK --set-mark 500 but I have no idea how to use tc update by running following commands, i managed to limit testuser upload bandwidth to 10Mbit iptables -t mangle -N HTB_OUT iptables -t mangle -I POSTROUTING -j HTB_OUT iptables -t mangle -A HTB_OUT -j MARK --set-mark 30 iptables -t mangle -A HTB_OUT -m owner --uid-owner testuser -j MARK --set-mark 10 tc qdisc replace dev eth0 root handle 1: htb default 30 tc class replace dev eth0 parent 1: classid 1:1 htb rate 10Mbit burst 5k tc class replace dev eth0 parent 1:1 classid 1:10 htb rate 10Mbit ceil 10Mbit tc qdisc replace dev eth0 parent 1:10 handle 10: sfq perturb 10 tc filter add dev eth0 parent 1:0 prio 0 protocol ip handle 10 fw flowid 1:10 now the problem is, i do not want to limit testuser's FTP bandwidth but by running above commands FTP speed also limited to 10Mbit.

  • What are the benefits of running a app server in user space, like Unicorn, as opposed to as sudo?

    - by dan
    I've been using Phusion Passenger + Rails/Sinatra for a lot of projects. Passenger runs under the main Nginx or Apache process. But I'm interested in Unicorn, partly because it runs in user space. You just set up Nginx to proxy_pass requests to a unix socket that is connected to Unicorn processes that you fire up under a normal user account. Is there anything to be said as far as advantages and disadvantages of these two alternative approaches to running an web app? I mean in terms of ease of administration, stability, simplicity, etc.

  • How do I keep a bridge enabled on a bonded interface?

    - by jlawer
    I'm working on setting up a pair of CentOS 6.3 servers that will run a couple of KVM vms and have come across a problem setting up a bridge on a bond. I am using Mode 4 (802.3ad) bonding on a pair of stacked Dell Powerconnect 5524 switches connecting to R320 servers. There are 2 links (1 to each switch) that form a Link Aggregation Group (802.3ad / LACP bonding). On top of the bond I have VLAN Tagging. I've verified this is a problem on multiple other bonding modes so it isn't just a mode 4 issue. I am testing what happens when 1 link is dropped (ie switch dies, cable breaks, etc). If I don't have a bridge (for KVM), everything works fine, failover happens as expected. If I have the bridge enabled, it works fine until failover (unplugging a cable). When failover happens /var/log/messages shows the slave link going down, followed within a second by: kernel: br1: port 1(bond0.8) entering disabled state The thing is /proc/net/bonding/bond0 shows the link is up as expected (simply with only 1 slave instead of 2). If I plug the cable back in it recovers and brings the bridge back to an enabled state. I actually have tested this while a ping is occuring and if the timing is right a packet will actually leave the system after the link is lost, but before the disabled message occurs. This disabled state I assumed was STP, but I have disabled STP on the bridge configuration and this issue still occurs. brctl showstp br1 still shows the link as disabled when it is running without a slave. I also switched between the nics in the server (I have 2x Broadcom & 4x intel). It doesn't matter which configuration I have. Does anyone know of a way to force the bridge to stay enabled or why its detecting the bond as disabled, when it isn't?

  • Gitolite and Gitlab - How the `www-data` user can checkout?

    - by mblaettermann
    I have just installed Gitolite and Gitlab and I am very happy with it. Everything works fine so far. I can create repos, push to them, clone them on other clients on the network. Great! But now I wanted to do some post-receive hooks. I.e. when I push to some repo, this repo should be checked out on the server in the /var/www/repos directory. I did this with Gitlabs Deploy Hooks and this Endpoint-Script. The problem is that the scripts are run under the user "www-data" which has no access to gitlab/gitolite. How do I change this? I need to be able to checkout repos with www-data user and using git@server/repo.git syntax.

  • How can I transfer a logged in user's login data from one server to another?

    - by Martin
    I have one server "A" where users can login. Login is verified by an LDAP server "L". I have a different server "B" were users can log in, too. Login is verified by the same LDAP server as before. Both servers are standard web servers with PHP. My goal is: If a user is logged in to server "A", and if he clicks a link to log in to server "B", the user should automatically be logged in without re-entering username and password. What is a good and secure way to achieve this? I can't submit username and crypted password to server "B". I can't use the PHP session of server "A", because it does not exit on "B". Cookies won't work either. I think that there is a way, but I just can't see it. Any help is very much appreciated.

  • Ldap access lists users even if user has no rights...

    - by Patkos Csaba
    I am trying to set up a more complex Active Directory structure for some testing purposes. What I did so far: set up 2 windows (one 2008 and one 2003) to control the same domain set up an Organizational Unit (ou): Developers set up 2 child OUs: "one" and "two" each OU has it's admin: adminOne and adminTwo I denied all access to OU "two" by removing on the Security tab all the groups I don't want to access it. now, when I log in as adminOne and I try to click on OU "two" it says I don't have permissions to see the users and properties of "two" - this is perfect, it's what I want Here comes my problem: I do a LDAP query with the adminOne user on the "Developers" What I expect to happen: I expect to retrieve the users from Developer - One I expect to NOT be able to retrieve the users from Developers - Two What actually happens: ldap shows all the users, both from Developers - One and Developers - Two, even if the user should not have permissions to Developers - Two And now my question: is there any specific settings on Windows 2003 or 2008 Active Directory servers which allow or deny access over LDAP? I could not find any.

  • Trying to get a new user up on pfSense IPSec VPN; Config file import failed, now getting gateway err

    - by Chris
    Caveat: I am not a sysadmin, so please forgive the n00bness of the query. We have a new user and I'm trying to get them up on VPN. We use pfsense as an IPSEC endpoint. This person is using Shrewsoft for the client. I had created an entry in pfsense for them and then edited a previous user's config file. Shrewsoft didn't import the config file very well and I had to hand edit the information. Now we are getting gateway errors. One thing I've noticed is that there is a different between the values of the preshared key stored on the firewall and the psk stored in the config file. I assume it has something to do with a hash, but I've no idea if that's the case and whether that might be what's causing the problem. Any suggestions greatly appreciated! Tangentially, is there some software used to generate these config files?

  • Simple mail server setup for a user-based website.

    - by Absolute0
    I am working on a simple website that has user registration. All I need to do is confirm email addresses by emailing a confirmation email and maybe send out periodic emails regarding various information. I am also considering having a [email protected] email for user questions and comments. The application is written in django and I am running it on ArchLinux on a VPS. I have no knowledge of mail servers. I tried setting up postfix and qmail but had no luck. They are complicated and require a lot of configuration to get them working properly. My use case is super simple and doesn't not require anything fancy. Is there any simple mailing setup that will enable me to quickly get emailing working with my django app with minimal work?

  • refresh windows network performance counters in command line

    - by michalv82
    I am testing a USB device connected to a windows PC. When the device is connected then windows has another network interface going through the device. I need to get the bytes transffered for that specific interface, basically I need the data shown in the networking tab in the task manager for my interface adapter. I found this question which helped to get this info: ms windows network activity bytes send and receive in command line However I have a problem when I run multiple tests - each time I disconnect and connect the device there's another line for the interface, like below. In the task manager networking tab I only see one record for my interface but I don't know how I can know from command line which is the lastest and current instance (it's not like the first line or last line is always the current interface, I noticed it's not consistent): wmic path Win32_PerfRawData_Tcpip_NetworkInterface Get Name,PacketsReceivedPerSec,PacketsSentPerSec,BytesReceivedPersec,BytesSentPersec BytesReceivedPersec BytesSentPersec Name PacketsReceivedPersec PacketsSentPersec 422666370 6317989292 Intel[R] 82579LM Gigabit Network Connection 2715169 8109643 49150 375973 My USB Device 432 568 0 0 My USB Device _2 0 0 0 0 My USB Device _3 0 0 0 0 My USB Device _6 0 0 0 0 Local Area Connection* 9 0 0

  • Windows AD: Is loopback processing absolutely necessary in order to apply a user policy to users logging into computers in the OU?

    - by Brett
    I've had our AD setup running on server 2008r2 and now 2012, and I swear, a user policy applied to an OU containing only computers actually does apply to users logging into those computers, without loopback processing enabled. Everything I read seems to say that is not how it should work, but it does. Is this normal behavior? Just tested again - created a policy with a drive map (which is a user policy), applied it to an OU containing my terminal server, forced a gpupdate, logged out/in, and sure enough, the drive is mapped. I did NOT turn on loopback processing.

  • Which permissions need to be assigned to a normal user to allow him to change SHARE permissions?

    - by guest
    As in the subject - I am wondering, which permissions (if it is possible) do I need to assign to a regular user to modify the share permissions - e.g. to add another user with full control permissions, or to deny someone read access to the folder - on a share level. I know that this is possible through NTFS permissions, but I am wondering whether it is also possible on share level. Any ideas how to do that? Or perhaps only the adminstrator/creator/person who shared the folder has the access to this? I am using win2003 Any ideas? Thanks

  • How can I set an arbitrary (non default) attribute for an AD user or AD Contact?

    - by makerofthings7
    I have AD Users, or contacts that are not Exchange Mailbox users, or contacts. I also have a SSO system (Ping Identity... technology similar to Microsoft ADFS), where it leverages the AD Schema attribute: CustomAttribute1 to store information needed for SSO. This CustomAttribute1 was created by the Exchange Schema. I would like to use CustomAttribute1 for both AD Users and AD Contacts, as well as the Exchange equivalent user and contacts. Question Since the Exchange tools will only allow me to modify "Exchange" users, what is the way to modify the AD counterpart? e.g. if the following command sets a mailbox... set-mailbox -Identity [email protected] -CustomAttribute1 [email protected] -WarningAction silentlyContinue What command will allow me to update an AD user (non-mailbox) under the same schema attribute?
