  • Internet Explorer not working after establishing a SSTP VPN connection

    - by Massimo
    I have a problem which is constantly appearing on each Windows 7 computer I'm using, whenever I establish a SSTP VPN connection to a ForeFront TMG 2010 firewall; it only happens with SSTP connections, not PPTP/L2TP ones. The problem appears only if using a proxy server for Internet access; it doesn't happen when directly accessing the Internet (with or without NAT). It doesn't seem to depend on a specific proxy software being used (I've seen it happening with various ones). The problem is: as soon as I start the VPN connection, Internet Explorer can't access anything anymore. I'm not using the VPN connection as a default gateway, and I can succesfully ping the proxy server after the VPN connection is esatablished (and even telnet to its 8080 TCP port), so this is definitely not a routing problem. Also, the problem is specifically related to Internet Explorer: while it seems not able to connect to any site, other programs (such as FireFox) have no problem accessing the Internet through the same proxy. This behaviour can be easily reproduced on any Windows 7 computer (the service pack and patch level doesn't seem to matter at all). Have IE connect through a proxy, establish a SSTP VPN connection... and IE will just not work anymore until the VPN connection is dropped.

  • Having problems VPN'ing into our Windows server network.

    - by Pure.Krome
    Hi folks, When two people (on their notebooks) try to VPN to our office, only the first user gets a connection. the second user always times out. Is it possible for VPN to allow two or more people, using / sharing the same EXTERNAL PUBLIC IP to connect/authenticate? Now for some specifics (cause those two statements are very broad). I'm not in the IT Dept. I'm a developer. Our IT Dept don't really care (sigh) so it's up to me to fix this crap. Our office is all Microsoft shop stuff - servers and clients. We also have a firewall (watchguard brand?) and some other crazy setups (yes i know, it's very vague :( ). So i'm wondering - is it possible for multiple users, from the same public IP, to connect via VPN to a windows server? i'm under the impression - yes. But it is possible that this only happens when the clients (who are all behind the single, public IP .. otherwise they will have their OWN ip's) need to have UPnP running or something? this is killing me and i need to start asking the right questions cause these guys don't know what they are doing and i can't work without this happening. I know this is a vauge question with so many 'if-what's-etc' but maybe some questions/suggestions from you guys might start to lead to solving this problem. EDIT: Network Connection: WAN Miniport (PPTP)

  • Virtualize SBS 2003 - P2V vs migrating to new VM

    - by jlehtinen
    I need to virtualize a SBS 2003 server in my work environment. I need some tips on what people think is the best way to proceed. Background: The SBS 2003 server is the primary DC for the domain and also hosts FTP, RRAS(VPN), DNS, and file shares. Exchange is NOT used, neither is SQL server. DHCP is done via a firewall appliance. I have added a Server 2003 VM to the domain and promoted it to the DC role. AD/DNS is replicating here correctly. This was mainly done to provide fault-tolerance to the domain, I was not intending to make this VM the primary DC. I've already asked about buying upgraded licensing for Server 2008/2012 but was refused due to cost. Options: I see (at least) two routes I could take to complete this. From what I've read option 2 is the "preferred" method, but there's a few steps where I'm not clear on what to expect. Option 1.) P2V the primary DC Power off primary DC Power off secondary DC (to prevent USN rollback in case P2V has issue) P2V (cold clone) primary DC Boot new PDC VM Allow new hardware to detect Remove old NIC hardware from device manager Assign old IPs to new virtual NICs Reboot PDC VM, confirm connectivity and no major issues Power on secondary DC, confirm replication Option 2.) Create new VM, transfer roles, remove original DC from domain Create new VM, install SBS 2003 Do I need the original SBS install discs for this? MS migration doc mentions this. Add VM to domain, promote to DC role Does this start 7 day timer where two SBS servers can be in same domain? Set up RRAS on new VM Set up IIS/FTP on new VM Move file shares to new VM Transfer FSMO roles to new VM DC dcpromo original primary DC out of domain

  • Disabling LDAP Signing on Windows PDC in Local Policy

    - by Golmaal
    I just tripped over my own feet it seems. Playing around on a Windows 2008 R2 server (set up as domain controller), I was intrigued by certain warning event (event id 2886) which says: "To enhance the security of directory servers, you can configure both Active Directory Domain Services (AD DS) and Active Directory Lightweight Directory Services (AD LDS) to require signed Lightweight Directory Access Protocol (LDAP) binds." So I thoughtlessly did some Googling and set the relevant policies which enforce LDAP signing. Now I don't remember but I may have done that using Local Policy. Now I have setup a pfsense box which must authenticate AD users via LDAP. While the firewall can communicate over secure channel, it is difficult to manage the same for other packages such as Squid and SquidGuard. So now I have to disable i.e. undo those policy changes. The problem is that they are greyed out! The policies in question are LDAP server signing and LDAP client signing. I don't remember what I did but when I access these policies from Local Policy editor on the server, they are set to "Require Signing" and are greyed out. The same policies can still be set via Default Domain Controller option in Group Policy editor. So how can I reset these greyed out policies? Thanks

  • "one-off" use of http_proxy in a Chef remote_file resource

    - by user169200
    I have a use case where most of my remote_file resources and yum resources download files directly from an internal server. However, there is a need to download one or two files with remote_file that is outside our firewall and which must go through a HTTP proxy. If I set the http_proxy setting in /etc/chef/client.rb, it adversely affects the recipe's ability to download yum and other files from internal resources. Is there a way to have a remote_file resource download a remote URL through a proxy without setting the http_proxy value in /etc/chef/client.rb? In my sample code, below, I'm downloading a redmine bundle from rubyforge.org, which requires my servers to go through a corporate proxy. I came up with a ruby_block before and after the remote_file resource that sets the http_proxy and "unsets" it. I'm looking for a cleaner way to do this. ruby_block "setenv-http_proxy" do block do Chef::Config.http_proxy = node['redmine']['http_proxy'] ENV['http_proxy'] = node['redmine']['http_proxy'] ENV['HTTP_PROXY'] = node['redmine']['http_proxy'] end action node['redmine']['rubyforge_use_proxy'] ? :create : :nothing notifies :create_if_missing, "remote_file[redmine-bundle.zip]", :immediately end remote_file "redmine-bundle.zip" do path "#{Dir.tmpdir}/redmine-#{attrs['version']}-bundle.zip" source attrs['download_url'] mode "0644" action :create_if_missing notifies :decompress, "zipp[redmine-bundle.zip]", :immediately notifies :create, "ruby_block[unsetenv-http_proxy]", :immediately end ruby_block "unsetenv-http_proxy" do block do Chef::Config.http_proxy = nil ENV['http_proxy'] = nil ENV['HTTP_PROXY'] = nil end action node['redmine']['rubyforge_use_proxy'] ? :create : :nothing end

  • Iptables rules, forward between two interfaces

    - by Marco
    i have a some difficulties in configuring my ubuntu server firewall ... my situation is this: eth0 - internet eth1 - lan1 eth2 - lan2 I want that clients from lan1 can't communicate with clients from lan2, except for some specific services. E.g. i want that clients in lan1 can ssh into client in lan2, but only that. Any other comunication is forbidden. So, i add this rules to iptables: #Block all traffic between lan, but permit traffic to internet iptables -I FORWARD -i eth1 -o ! eth0 -j DROP iptables -I FORWARD -i eth2 -o ! eth0 -j DROP # Accept ssh traffic from lan1 to client 192.168.20.2 in lan2 iptables -A FORWARD -i eth1 -o eth2 -p tcp --dport 22 -d 192.168.20.2 -j ACCEPT This didn't works. Doing iptables -L FORWARD -v i see: Chain FORWARD (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 33 144 DROP all -- eth1 !eth0 anywhere anywhere 0 0 DROP all -- eth2 !eth0 anywhere anywhere 23630 20M ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED 0 0 ACCEPT all -- eth1 any anywhere anywhere 175 9957 ACCEPT all -- eth1 any anywhere anywhere 107 6420 ACCEPT all -- eth2 any anywhere anywhere 0 0 ACCEPT all -- pptp+ any anywhere anywhere 0 0 ACCEPT all -- tun+ any anywhere anywhere 0 0 ACCEPT tcp -- eth1 eth2 anywhere server2.lan tcp dpt:ssh All packets are dropped, and the count of packets for the last rule is 0 ... How i have to modify my configuration? Thank you. Regards Marco

  • SQL Server Instance login issue

    - by reallyJim
    I've just brought up a new installation of SQL Server 2008. I installed the default instance as well as one named instance. I'm having a problem connecting to the named instance from anywhere besides the server itself with any user besides 'sa'. I am running in mixed mode. I have a login/user that has a known username. Using that user/login, I can properly connect when directly on the server. When I attempt to login from anywhere else, I recieve a "Login failed for user ''", with Error 18456. In the log file in the server, I see a reason that doesn't seem to help: "Reason: Could not find a login matching the name provided.". However, that user/login DOES exist, as I can use it locally. There are no further details about the error. Where can I start to find something to help me with this? I've tried deleting and recreating the user, as well as just creating a new one from scratch--same result, locally fine, remotely an error. EDIT: Partially Resolved. I'm now passed the base issue--the clients were trying to connect via the default instance. I don't know why. So, once proper ports were opened in the firewall, and a static port assigned to the named instance, I can now connect--BUT ONLY if I specify the connection as Server,Port. SQLBrowser is apparently not helping/working in this case. I've verified it IS running, and done a stop/restart after my config changes, but no difference yet.

  • Cherrypy web application won't communicate outside localhost via VPN

    - by Geoffrey Shea
    I'm trying to run a Python2.7/Cherrypy web server on Win 7 which is connected to a VPN to establish a dedicate IP address. (If I run the exact same application on Win XP connected to the VPN it works fine.) On Win 7 I tried configuring it to use port 8080, 8005, or 80 with no improvements. I turned off Windows Firewall altogether to test and there was no improvement. If I run Apache on the Win 7 machine on port 80 it works fine so I'm pretty sure it's not the VPN service or router. If I go to WhatismyIP.com it shows that I have the IP address being provided by the VPN. Here is the Python code, but I suspect the problem is the network configuration: import cherrypy class HelloWorld: def index(self): return "Hello world!3" index.exposed = True cherrypy.root = HelloWorld() cherrypy.config.update({"global":{ "server.environment": "production", "server.socketPort": 8005 } }) cherrypy.server.start() This will return a web page if I go to localhost:8005, but not if I go to the VPN IP address:8005 from another machine. As I said, if I run Apache on the Win 7 machine on port 80 I can see it at localhost:80 AND at the VPN IP address:80 from another machine. Thanks for any light you can shed! Geoffrey

  • Administrative shares in Windows 7 Pro not visible

    - by Chris Tybur
    My desktop machine has a clean install of Windows 7 Professional. For some reason the standard administrative shares Admin$, C$, D$, etc are not visible, either in Computer Management - Shared Folders - Shares or via net share. I also have a laptop with a clean install of Windows 7 Professional, and I can see the admin shares in both places. As such, I can map to \\laptop\c$ from the desktop, but I can't map to \\desktop\c$ from the laptop. I pretty much took the defaults during the Windows 7 installations. I've tried adding LocalAccountTokenFilterPolicy to the registry on the desktop, but that didn't work. On the desktop I've also disabled UAC, turned off Windows firewall, removed it from a homegroup, made sure file and printer sharing is turned on, but nothing has worked. There is some subtle difference between the two machines that I can't seem to find. I'm logging into both machines using a local account that is in the Administrators group. Both accounts have the same name and password. I really don't want to have to create a new share for the desktop's C drive, especially since C$ is visible and working on the laptop and therefore I should be able to make it work on the desktop. Any idea why the admin shares would work on one machine and not another? Or why LocalAccountTokenFilterPolicy would fail?

  • postfix - connection refused from behind NAT

    - by manchine
    When attempting to telnet postfix from a different host in the same LAN through the FQDN (and thus the LAN's public IP), the following error occurs: root@mailer:/var/log# telnet mail.domain.com 25 Trying 1.2.3.4... telnet: Unable to connect to remote host: Connection refused Other services can be reached from the exact same host, however: root@mailer:/var/log# telnet mail.domain.com 22 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u1 To make matters more intriguing, Postfix can be accessed from outside the LAN: nunos-mbp:mailog nzimas$ telnet mail.domain.com 25 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com ESMTP Postfix (Ubuntu) To sum thing up: a) Postfix (running on 10.10.10.4 / mail.domiain.com) refuses connection from a host in the same LAN (10.10.10.2), but only when queried through the FQDN (mail.domain.com) b) mail.domain.com accepts connections to other services (but Postfix) from 10.10.10.2 c) mail.domain.com accepts connections to all services, including Postfix, from the outside world If it were a firewall issue, then I believe it would not be possible to connect to any service from 10.10.10.2 through the FQSN / public IP. It ought to be some missing parameter in Postfix, although I haven't found any clear pointers so far.

  • New SBS 2011 installation (not migration) in an existing 2008 R2 domain

    - by Tong Wang
    My current network setup has two servers: a Windows 2008 R2 with TMG 2010 as edge firewall (TMG server), a second 2008 R2 with DC, DNS and Hyper-V roles (DCDNS server). I was trying to install SBS 2011 as a child partition on DCDNS, first I installed SBS 2011 in English and did the migration successfully. However, later on, I found that I can't change the display language in SBS 2011 once it's installed (but the clients require a different language), so I had to re-install the SBS in a different language. It is during the re-installation that the problem came up: the migration can't be completed with some error message stating "can't access the source server". I re-ran the migration preparation tool, but it didn't make any difference. I wonder if it's because the source server can only be "migrated" once. Since I only need to setup a handful of users and computers, so I decided to do a new install of SBS and picked a different domain name. But I can't get the SBS to connect to LAN: it can't ping other servers, neither can other servers ping the SBS server. I've tried to stop the DC/DNS services on DCDNS and restart SBS, but with no difference. Anyone has idea how to fix this problem?

  • Access node.js local server though mobile via same shared wifi

    - by laggingreflex
    EDIT: I was stuck in this situation before but then it was Apache-related But this time I'm using NodeJS, so the old answer doesn't help. I'm running apache a NodeJS webserver (on port 80) on Windows 7. I want to access the webserver through my mobile which shares the wifi router with my pc locally. http://localhost works from PC. But I can't access http://192.168.1.4 from either my phone or even my computer. ipconfig /all on my computer lists my ip address as 192.168.1.4 Wireless LAN adapter Wireless Network Connection: IPv4 Address. . . . . . . . . . . : 192.168.1.4(Preferred) I can ping my phone's (internal) ip address [192.168.1.5] from PC and vice-versa, I can ping my PC [192.168.1.4] from my phone. So why can't I access http://192.168.1.4 from my phone? (or PC) Firewall is off.

  • Backup files from Linux client to Windows Server

    - by Andrew
    I'm trying to backup my files from my Linux box to my Windows Server 2008 as a push, and when I delete them from my Linux box, they remain on my Windows Server. I've found lots of sources that are similar, but most results were from Windows to Linux. I managed to find slightly more similar cases like Using rsync and cygwin to Sync Files from a Linux Server to a Windows Notebook PC, and rsync from Windows PC to remote Linux server, with the most similar being a backup from Linux to Windows Server, but through a pull from the Windows Server. Initially, I used Unison because I thought having the 2-way capability would come in handy, and I would just have to set some configurations to make it 1-way. Unfortunately, I couldn't find the right configuration, and only managed to synchronize using the command unison "profile" -ui text -auto -silent. When I deleted the files on my Linux box, the files in the Server got deleted too, which of course, isn't what I want. When I tried to find any options for Unison, I only discovered the -force option, which didn't help, since what I wanted was an incremental update to the Server. I found out I could achieve this from using rsync and the -a option (archive), which would keep adding files even if I deleted them from my Linux box. I installed Cygwin on my Windows Server, configured an SSH daemon, but I can't seem to get it working. I've also already configured Windows Firewall to open port 22 (both inbound and outbound). I used the following command from my Linux box: rsync -avrzn /folder/to/be/backed/up/ [email protected]:/cygdrive/c/place/to/store/backed/up/files (a - archive, v - verbose, r - recurse into subdirectories, z - compress, n - dryrun) but it just won't work. Can anyone help me out? I don't mind using either Unison or rsync, as long as it achieves what I want.

  • Slow connection to Linux MySQL from Windows only (XAMPP)

    - by Josh
    I'm having a problem with a PHP project (using Kohana 3.2 framework) on my Windows 7 64-bit machine connecting to the database. The development database is stored on a Ubuntu Linux server on the local network. Other development machines running OSX and Linux are connecting fine. There are no other Windows development machines to test with. I can access MySQL fine using MySQL Workbench, and other projects (which I believe to be less database heavy) run mostly ok, only occasionally getting timeout messages. I'm constantly getting Maximum execution time of 30 seconds exceeded when functions such as mysql_query() are run in this particular project. Specifically, the Kohana file where the timeout occurs is MODPATH\database\classes\kohana\database\mysql.php [ 186 ]. My local set-up is: Windows 7 Professional 64bit XAMPP 1.7.7 (PHP 5.3.8) The output of uname -a of the Linux server is: Linux peach 2.6.38-11-server #50-Ubuntu SMP Mon Sep 12 21:34:27 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I've tried the following, with no success: Disabling Windows firewall Switching between using a persistant and normal connection In my.cnf, adding skip-name-resolve Increasing wait_timeout Enabling bind-address I've run out of ideas now, and have no idea how to debug an odd issue like this. Has anyone come across this before, or have any idea how I could find the root of the issue, or what might be the problem?

  • Moving Microsoft Exchange server to the private network.

    - by Alexey Shatygin
    In one of the offices, we have a 50-computers network, which had only one server machine: Windows 2003 Server Microsoft ISA Server Microsoft Exchange 2003 This server worked as a gateway (proxy server), mail server, file server, firewall and domain controller. It had two network interfaces, one for WAN (let's say 222.222.222.222) and one for LAN (192.168.1.1). I set up a Linux box to be the gateway (without a proxy), so the Linux box now has the following interfaces: 222.222.222.222 (our external IP, we removed it from the Windows machine) and 192.168.1.100 (internal IP), but we need to keep the old Windows server as a mail server and a proxy for some of our users, until we prepare another Linux machine for that, so I need the mail server on that machine to be available from the Internet. I set up iptables rules to redirect all the incoming connections on the 25th and 110th ports of our external IP to 192.168.1.1:25 and 192.168.1.1:110 and when I try to telnet our SMTP service telnet 222.222.222.222 25 I get the greetings from our windows server's (192.168.1.1) SMTP service, and that's works fine. But when I telnet POP3 service telnet 222.222.222.222 110 I only get the blank black screen and the connection seem to disappear if I press any button. I've checked the ISA rules - everything seems to be the same for 110th and 25th ports. When I telnet on 110th ports of our Windows server from our new gateway machine like this: telnet 192.168.1.1 110 I get the acces to it's POP3 service: +OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 (...) ready. What sould I do, to make the POP3 service available through our new gateway?

  • Instructions to setup primary and only domain controller

    - by Robert Koritnik
    Where could I get best step by step instructions (with some simple explanations) how to setup domain controller on Windows Server 2008 R2 Server Core? I don't know what do I need? Do I need DNS as well and AD and so on and so forth. I don't know enough about these things, but I need to set them up to prepare development environment. I would also like to know how to configure firewall on DC machine, to make it visible on other machines because I've setup DC somehow but I can't connect to it... This is my HW config: Linksys internet router with DHCP my dev machine is Windows 7 my DC machine is a VM in my dev machine my dev machine has a hw network adapter to linksys and a virtual network adapter to DC DC machine has two network adapters: one to linksys (to be internet connected so it can be updated etc.) and one to host (my dev Win7 machine) Edit My development machine should access domain controller and logon using domain credentials. Development machine would access internet directly via Linksys router. My domain controller machine would only serve authentication (and if I'm able to configure it right) should also have Active Directory Federation Services in a workable condition. I hope this is a bit more clear now. At least a small bit.

  • Cisco ASA user authentication options - OpenID, public RSA sig, others?

    - by Ryan
    My organization has a Cisco ASA 5510 which I have made act as a firewall/gateway for one of our offices. Most resources a remote user would come looking for exist inside. I've implemented the usual deal - basic inside networks with outbound NAT, one primary outside interface with some secondary public IPs in the PAT pool for public-facing services, a couple site-to-site IPSec links to other branches, etc. - and I'm working now on VPN. I have the WebVPN (clientless SSL VPN) working and even traversing the site-to-site links. At the moment I'm leaving a legacy OpenVPN AS in place for thick client VPN. What I would like to do is standardize on an authentication method for all VPN then switch to the Cisco's IPSec thick VPN server. I'm trying to figure out what's really possible for authentication for these VPN users (thick client and clientless). My organization uses Google Apps and we already use dotnetopenauth to authenticate users for a couple internal services. I'd like to be able to do the same thing for thin and thick VPN. Alternatively a signature-based solution using RSA public keypairs (ssh-keygen type) would be useful to identify user@hardware. I'm trying to get away from legacy username/password auth especially if it's internal to the Cisco (just another password set to manage and for users to forget). I know I can map against an existing LDAP server but we have LDAP accounts created for only about 10% of the user base (mostly developers for Linux shell access). I guess what I'm looking for is a piece of middleware which appears to the Cisco as an LDAP server but will interface with the user's existing OpenID identity. Nothing I've seen in the Cisco suggests it can do this natively. But RSA public keys would be a runner-up, and much much better than standalone or even LDAP auth. What's really practical here?

  • Hadoop streaming job on EC2 stays in "pending" state

    - by liamf
    Trying to experiment with Hadoop and Streaming using cloudera distribution CDH3 on Ubuntu. Have valid data in hdfs:// ready for processing. Wrote little streaming mapper in python. When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

  • Juniper NetScreen NS-5GT traffic monitoring

    - by blah
    I've done casual research into the subject and am truly dismayed at the lack of compatible tools for such a simple task. Maybe someone can provide assistance. We have a NetScreen NS-5GT in the office. I need to be able to get a glance of current traffic per endpoint -- I think the equivalent of 'get sessions' with byte counts/rates. I don't care about bars, graphs, and reports. Something as simple as a classic software firewall display would be perfect. I can't shell out money on something real like SolarWinds products, so a free solution is essential. I'm willing to do a little work but refuse to program something from scratch. It's not prudent right now for me to install a hub or otherwise mess around physically. There must be something out there I can use, maybe in combination. I don't believe I'm asking too much. Specific answers only please, e.g. monitoring software you know will actually work with this antiquated device. I've read about general approaches to the broader problem dozens of times already.

  • Windows 7 can't find Ubuntu computer by hostname

    - by endolith
    I got a new Windows 7 machine, and was using VNC, SSH etc to connect to my Ubuntu machine, and it worked fine previously connecting to the Ubuntu computer's hostname. Now it doesn't work if I use the machine's hostname, but it does if I use the local IP or DynDNS name. I can also access it from my Android phone using the local hostname over SSH. If I try to connect with SSH to the hostname, it says "Host does not exist". VNC says "Failed to get server address". NX says "no address associated with name", and I don't see it in Windows' "Network" folder. I've rebooted everything. I've turned off Windows firewall. It was working fine a few days ago, but now it's not. How do I figure out what's blocking it? Aha: It probably has something to do with Samba. I reset the Samba configuration the other day, and apparently this can affect it. http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=1558925 I tried commenting out "encrypt passwords = No" as described there, but it still doesn't work.

  • vSphere Promiscuous mode only receiving packets one way from network switch

    - by steve.lippert
    We have two network switches, a POE switch (SwitchA) to power our phones / users computers and a non-POE switch (SwitchB for the rest network.) Each switch is setup to do port mirroring to support our VoIP recording system. SwitchA does port mirroring on specific ports if we need to record a user. SwitchB mirrors one port to monitor our work at home users (Internet comes in from managed router, to switch, back out to our firewall.) These two port mirroring setups feed into one vmware vSphere 4.1 server, it has four total physical cards. The other two NICs feed into an unmanaged switch for connecting to the rest of the network. Once into the vSphere server all network ports go into a vSwitch, and then one of the servers (Windows 2008 R2) sniffs them out and does its thing. Everything is working fine and dandy from SwitchB. But on SwitchA we only receive one side of the VoIP packets (going out to the phone, nothing coming in from the phone). Troubleshooting steps I have taken so far: I hooked up my laptop to the monitor port on SwitchB and I see both sides of the packets. I swapped which network interface is plugged into the monitor port on SwitchA. Because everything feeds into one vSwitch / vNetwork and both sides of the conversation arrive just fine from SwitchB I believe everything is configured correctly on the vSphere server/guest. What could be causing one way packets to arrive on my guest machine from only one interface, but not the other? Could a bad cable be causing the problems from SwitchB?

  • Connection between Asp.Net and Oracle 10g Express Edition

    - by l3gion
    Hello, I'm struggling to find a way to connect my Asp .Net + C# application with my Oracle 10g Express Edition. Here's my scenario, I'm at Mac OS and I have 2 Virtual machines, one for Win 7 (VS 2010 app) and another with a Parallels Virtual Appliance with Oracle 10g Express Edition 1.1. Which provider (Oledb, ODP.NET, etc..) should I use? How to make the connection to the server in C#? Right now I have this: <appSettings> <add key="conn" value="Data Source=10.211.55.11;Persist Security Info=True;User ID=l3gion;Password=l3gion;" /> </appSettings> And at the .cs file: SqlCommand cmd = new SqlCommand("insert_thing", new SqlConnection(ConfigurationManager.AppSettings["conn"])); cmd.CommandType = CommandType.StoredProcedure; *insert_thing is a stored procedure Using this I got this error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I've searched for some possible solutions. Tried some, including: firewall disabled, allow remote connection at oracle express edition using this cmd line ("EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);").. The error persists. Can anyone guide me into the right direction? I'm a newbie with this type of things. Thank you for your patience. regards

  • Can't connect to Server Manager from Windows 7

    - by SAdmin317
    I have a Windows 7 Pro 64bit with SP1 desktop that has RSAT tools installed. I opened Server Manager and can't connect to the server (Server 2008 R2 core). I followed the guide to enable everything on the server, added a registry key to enable read-only on the device manager as well. On the Windows 7 PC I turned on winrm, did the quick config, and added the server IP and name as trusted hosts. I still get an error when connecting. "Connecting to the remote server failed with the following error message: The WinRM client cannot process the requests. If the authentication scheme is different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts configuration setting...." I also added the name of the server to the windows 7 /etc/hosts file. Ping the server name translates to the IP of the server. Also opened up the firewall for "Remote Volume Management" Both machines are on the same Workgroup, using the same Administrator account, with the same password. Any help appreciated.

  • Windows 8 using as a webserver

    - by Jason
    I have a few hobby websites that I currently host on CentOS 6. Apache, mail serving, PHP, MySQL nothing special. In the past I used Windows XP to do this same task, for years, and I was OK. I switched to Linux and for the last few years it has been such a pain. updates break, certain apps only support certain distros without compiling from source. It prevents me from working on my hobby sites more because I am always fixing something. With Windows I locked it down, I run a hardware firewall and packet analyser, kept up on updates and A/V and never had a problem. I dont allow RDC from outside the local LAN, no FTP open, run OpenSSH on an obscure port.. I am considering switching to Windows 8 (since it is a cheaper license now that Windows 7) and running apache, HMailServer, PHP, MySQL, just like my CentOS install. My questions: I am not familiar with Windows 8, can the above be done like XP? No new security restrictions or the OS preventing this from happening? The machine is a Athlon 64-bit X2 with 32GB of RAM. Will Windows 8 see all of the RAM? Technically the machine came with Windows 7, and there is a serial number on it but I am sure I wiped away the Windows 7 recovery partition when I switched to Linux....

  • "Access is Denied" when executing application from Command Prompt

    - by xpda
    Today when I tried to run an old DOS utility from the XP Command prompt, I got the message "Access is Denied." Then I found that most of the DOS utilities would not run, even though I have "full control" over them. They worked just fine a few weeks ago, and I have not made any OS changes other than Windows Upgrades. Then I tried running edlin.exe and edit.com from the Windows\system32 folder. Same result - "Access is Denied." I tried running these applications from Windows Explorer and got the message "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I am logged in as a member of Administrators and have full control over these files. I tried logging in as THE Administrator, with no change. I checked the security settings on the files, and have full control over all of them. I have tried copying the files to different drives, booting in safe mode, and running without antivirus and firewall, all with no change. Does anybody know what could cause this?
