  • RTS Game Style Application [closed]

    - by Daniel Wynand van Wyk
    My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!

  • Oracle Application in DMZ (Demilitarized Zone)

    - by PRajkumar
     Business Needs Large Organizations want to expose their Oracle Application services outside their private network (HTTP/HTTPS and SSL). Usually these exposures must exist to promote external communication. So they want to separate an external network from directly referencing an internal network   Business Challenges ·         Business does not want to compromise with security information ·         Business cannot expose internal domain or internal URL information   Business Solution DMZ is the solution of this problem. In Oracle application we can achieve this by following way –   ·         Oracle Application consists of fleet nodes (FND_NODES) so first decide which node have to expose to public ·         To expose the node to public use the profile “Node Trust Level” ·         Set node to Public/Private (Normal -> private, External -> public) ·         Set "Responsibility Trust Level" profile to decide whether to expose Application Responsibility to inside or outside firewall         Solution Features   ·         Exposed web services can be accessed by both internal and external users ·         Configurable and can be very easily rolled out ·         Internal network and business data is secured from outside traffic ·         Unauthorized access to internal network from outside is prohibited ·         No need for VPN and Secure FTP server   Benefits  ·       Large Organizations having Oracle Application can expose their web services like (HTTP/HTTPS and SSL) to the internet without compromise with security information and without exposing their internal domain   Possible Week Points  ·         If external firewall is compromised, then external application server is also compromised, exposing an attack on E-Business Suite database ·         There’s nothing to prevent internal users from attacking internal application server, also exposing an attack on E-Business Suite database   Reference Links  ·         https://blogs.oracle.com/manojmadhusoodanan/tags/dmz

  • Can't access some websites using Ubuntu 13.10

    - by Adame Doe
    Something's wrong with Ubuntu. Since I've upgraded to 13.10, I can't access some websites for no apparent reason. I've tried everything imaginable to solve this problem : Made sure that MTUs are the same, Disabled IPv6 in both the network manager and used browsers, Deactivated my network keys, DMZed my computer, Used other DNS like Google and OpenDNS, Checked that no firewall was running my computer ... And it's the same result. I even tried to reinstall Ubuntu a couple of times, but no luck. The most annoying thing about it is I can't access wordpress.org! So, there's no way it could be an ISP restriction of some kind. When I use a VPN, I can access pretty much anything. I'm really frustrated because I have to use wordpress.org very often. Any clue? ifconfig adame@adame-ws:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:26:18:3d:b0:7c inet addr:10.42.0.1 Bcast:10.42.0.255 Mask:255.255.255.0 inet6 addr: fe80::226:18ff:fe3d:b07c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:8024 errors:0 dropped:0 overruns:0 frame:0 TX packets:7966 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:684480 (684.4 KB) TX bytes:616608 (616.6 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:8222 errors:0 dropped:0 overruns:0 frame:0 TX packets:8222 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:568269 (568.2 KB) TX bytes:568269 (568.2 KB) wlan0 Link encap:Ethernet HWaddr 00:19:70:40:85:eb inet addr:192.168.2.3 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::219:70ff:fe40:85eb/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1464 Metric:1 RX packets:123705 errors:0 dropped:0 overruns:0 frame:0 TX packets:98141 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:94963545 (94.9 MB) TX bytes:10387470 (10.3 MB) /etc/hosts 127.0.0.1 localhost 127.0.1.1 adame-ws ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters tracepath wordpress.org 1: adame-ws.local 0.092ms pmtu 1500 1: 192.168.2.1 1.300ms asymm 2 1: 192.168.2.1 1.060ms asymm 2 2: no reply 3: no reply 4: no reply 5: no reply 6: no reply 7: no reply 8: no reply ... keep on going like that ping wordpress.org adame@adame-ws:~$ ping wordpress.org PING wordpress.org (66.155.40.250) 56(84) bytes of data. --- wordpress.org ping statistics --- 10 packets transmitted, 0 received, 100% packet loss, time 9071ms

  • Watchguard SSLVPN user connection issue

    - by Tory Newnham
    I have a user that needs access to our SSLVPN on our Watchguard firewall from his company issued laptop. The problem is when he tries to connect as himself he cannot connect. If I login to the machine it works fine, if I add him to the domain admins group in Active Directory it works fine… So, we know it is an access issue but I cannot figure out what access he needs. He is in the SSLVPN-Users group which I thought would give them all the access they needed but apparently not… Here is the output of the SSLVPN Logs when trying to connect: 2012-09-14T15:40:55.834 Launching WatchGuard Mobile VPN with SSL client. Version 11.5.3 (Build 339447) Built:Apr 5 2012 00:25:00 2012-09-14T15:41:18.832 Requesting client configuration from X.X.X.X:443 2012-09-14T15:41:20.386 VERSION file is 5.15, client version is 5.15 2012-09-14T15:41:21.924 Error: connect() failed. ret = -1 errno=10061 (...) 2012-09-14T15:41:23.960 Error: connect() failed. ret = -1 errno=10061 2012-09-14T15:42:00.788 Failed Launch Has anyone had the same issue, or have any ideas on what Group Policy changes need to be made in order for him to have access but not be a Domain Admin?

  • pfSense Firewall or Linsys/Cisco router for small offices

    - by Tim Meers
    I'm about to start switching some networks around for multiple small offices. Each office has about 10 to 15 users and 10 to 15 computers. Each office has a spread of generic routers and access points. The routers vary from being used as routers, to just being an access point for wireless. Nothing formal has really ever beem implemented for each of the 10 offices. What I'm wanting is to set up a pfSense box for each office to configure things like: traffic shaping (for VoIP QOS) URL Filtering DHCP static routing multiple VLANs I'll then use some of the existing hardware for wireless. Maybe even integrate the wireless right into the firewall depending on the office layout. So my question, would this be better to do a full blown firewall box, or but a new business class or high end consumer class Linksys router to do the URL filtering, QOS and DHPC? Each option could allow for remote access and VPN for remote maintnance and each would only cost a nominal about of money for something decent, i.e. under $250.

  • Cisco ASA intermittently fails to see traffic

    - by DrStalker
    users | Mikrotik -- Internet | ASA | ServerA and ServerB I'm trying to troubleshoot a problem with a new Cisco ASA 5505. The network design is as above - the Microtik is the existing router, ServerA and ServerB used to plug directly into it. ServerA has IP 10.30.1.10, ServerB has IP 10.30.1.11 The ASA is configured with no NAT, a "allow anything" firewall, and uses the microtik as its default gateway. In effect, it is currently a simple IP router; the firewall and VPN stuff will all come later once the basics are working. Th problem is access to ServerA and ServerB is erratic - sometimes it will work, sometimes it will fail. It can fail for either one of the servers only, or both. When it is working: The Mikrotik logs show ping packets being sent out over the proper interface The ASA logs show the incoming connections. When it is failing: The Mikrotik logs show ping packets being sent out over the proper interface The ASA logs show nothing reaching the ASA. This can fail for one server only (e.g.: the Mikrotik is putting out packets to 10.30.1.10 and 10.30.1.11, but the ASA is only seeing packets arrive destined for 10.30.1.11) It can fail for one source only (e.g.: ClientA on the users network can ping 10.30.1.11, but clientB cannot) The problem can also be seen from the mikrotik router itself; sometimes it can ping ServerA and ServerB, sometimes it can only ping one of them What could be causing this? I can't think of any possible cause that is intermittent and could explain why the problem may occur for one destination server and not others. edit: Link to ASA config

  • Fortinet: Is there any equivalent of the ASA's packet-tracer command?

    I would like to know if there is not Fortigates an equivalent of the packet-tracer command that we can find on the ASA.

  • Writing a script for ash?

    - by rumtscho
    My VPN is behaving funny sometimes, and I have to restart it often. I wanted to write a script which does that for me. It doesn't have to be anything fancy, just a shortcut for the commands I have to type into the terminal. More specifically: it will look at the running processes. If it finds a running vpnc process, it will kill it. Then it will start vpnc. I've written bash scripts of similar complexity, but now I don't have a bash, only an ash. Until now, the only difference I noticed is that there are much less commands available, but then, I don't use it very often. So I have some questions. Is writing ash scripts different than writing bash scripts? Is there something specific to consider when doing it? When the script is ready, how can I deploy it? For bash, I just put the executable file under /usr/lib and run it by typing the file name into the command line, will this work with ash? Are there any special pitfalls to watch out for in the script I want to write? I think that the killing process part may get hairy, if I write something that kills the wrong process, but even then running the script shouldn't break anything permanently, right?

  • Windows Server (SBS) 2008 - Telephony service won't start (missing permissions)

    - by Uri
    I am running a SBS 2008 server. It's setup as the domain controller for the network. After a reboot, the Telephony service (and all services that depend on it) refuses to start under the Network Service account. The error given is: Error 1297: A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration. This has caused all the network services not to be accessible e.g. terminal services, VPN (RRAS), SQL Server instances. The SSH daemon I have running on the box will accept connections only from localhost, but won't respond on the network. After searching around, the only advice I could find was to grant the Network Service account these permissions: Adjust memory quotas for a process Replace a process level token I set those permissions on both the Default Domain Policy and the Default Domain Controller Policy, but it seemingly had no effect. Most of the services will start if I change them to run under the Local System account, but that didn't make them accessible on the network. I even tried removing the Routing and Remote Access Services feature, rebooting and reinstalling it, but the issue remains. Any ideas?

  • Windows 7, network connection with no default gateway: any way to change the "Unknown network" statu

    - by e-t172
    Hi, I have a computer running Windows 7 Pro RTM. This computer has two network connections: A Wi-fi connection to the Internet (through a home router) which works just fine. An OpenVPN virtual network connection. More precisely, this is a virtual Ethernet connection which behaves exactly like a physical Ethernet wired connection. My problem is that the "Network and sharing center" shows "Unknown network" for the OpenVPN connection. After some research I found that logical networks (outside a domain) are identified by the MAC address of the default gateway of the connection. Problem is, the OpenVPN connection has no default gateway: it is a private network, so I don't need one... Consequently, the "Unknown network" is always considered public, so the firewall is always in "public mode", which I don't want. Plus, I can't rename "Unknown connection" or anything (which makes sense), so it is kinda ugly. My goal is to define a proper logical network for the OpenVPN connection with the private profile. I know of some workarounds (disable the firewall, modify security policy to make all unknown networks "private") but they're still workarounds. I just want my clients to connect to the VPN without having to disable their firewall settings, without changing global configuration with potential side-effects (the "security policy" solution) and without having to look at an ugly "Unknown connection" in the Network and sharing center. Is there any way I can do this? I tried to check what was going on in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList is interesting), but I still didn't find a way to "force" the OpenVPN connection to be assigned to a logical network. Any help would be very appreciated. A related question showed up at Superuser: http://superuser.com/questions/37355/windows-7-cant-identify-network/37422

  • Using VLANs/subnetting to separate management from services?

    - by YouAreTheHat
    Background: I recently purchased a server and a managed switch for my home in the hopes of getting more experience and some fun toys to play with. The devices and appliances I either have or plan to have cover a broad spectrum: router, DD-WRT AP, Dell switch, OpenLDAP server, FreeRADIUS server, OpenVPN gateway, home PCs, gaming consoles, etc. I intend to segment my network with VLANs and associated subnets (e.g., VID10 is populated by devices on 192.168.10.0/24). The idea is to secure the more sensitive appliances by forcing traffic through my router/FW. Setup: After thinking and planning for some time, I have tentatively decided on 4 VLANs: one for the WAN connection, one for servers, one for home/personal devices, and one for management. In theory, the home VLAN will have limited access to the servers, and the management VLAN will be totally isolated for security. Question: Since I want to restrict access to management interfaces, but some appliances have to be accessible to other devices, is it possible/wise to have only management (SSH, HTTP, RDP) available on one VLAN/IP and only services (LDAP, DHCP, RADIUS, VPN) available on other? Is this a thing that is done? Does it gain me the security I think it does, or hurt me in some way?

  • Unable to install PEM/pkcs12 created by gnutls to Cisco ASA

    - by ACiD GRiM
    I've been pulling some hair out trying to figure out why cisco devices don't like my certificates. My primary need is to get a trustpoint set up with CA,cert,key on the ASA for VPN systems, however I'm having the same issues on my IOS devices. I created a pkcs12 with openssl a few months ago that imported with no issues, but now that I'm getting ready to move this lab to production I'm using gnutls certtool as I found it adds alt_dns and ip_address fields properly to the certificate, (which cost me a few more hairs trying to get to work with openssl's ca tool) I'm including the current test certs below, don't worry I'm not using these in production ;) The maddening thing is that after I thought gnutls was generating certs incorrectly, I tried making a pkcs12 for a printserver and it imported with no issues. Here's my command flow for creating these certs: certtool --generate-privkey --disable-quick-random --outfile nn-ca.key certtool --generate-self-signed --load-privkey nn-ca.key --outfile nn-ca.crt certtool --generate-privkey --disable-quick-random --outfile nn-g0.key certtool --generate-certificate --load-privkey nn-g0.key --outfile nn-g0.crt --load-ca-privkey nn-ca.key --load-ca-certificate nn-ca.crt openssl pkcs12 -export -certfile nn-ca.crt -in nn-g0.crt -inkey nn-g0.key -out nn-g0.p12 openssl enc -base64 -in nn-g0.p12 -out nn-g0.base64.p12 The password for the attatched pkcs12 is "ciscohelp" without quotes.

  • Recommendations for secure business collaboration tools

    - by Michael Prescott
    I'm searching for a secure and easy way for business partners to collaboratively edit and exchange documents, share calendars, create schedules, and assign tasks. I speculate that the ideal collaboration environment or work-flow would actually involve several technologies and services. My co-workers and I have tried a variety of things from Google Apps to Wiki's, but nothing feels very fluid or complete. I suppose defining what we need and our constraints is probably in order: collaboratively edit basic text documents and spreadsheets exchange documents like flow-charts, graphs, and files generated by our other desktop applications, but not source code assign tasks to each other and ourselves and track the history of those tasks easily see when relevant documents have been modified since last viewing and ability to easily push notifications to relevant workers (a clean front page that shows updates would probably suffice) provide limited access to contract workers and guests users if a remote user system is compromised (keystroke logger or other spyware) we don't want the criminal to be able to gain access to all business documents (processes, trade-secrets, customer lists, etc.) simply because they gained access to a single Google account (or whatever web service) Cannot be a difficult to administer VPN infrastructure Cannot cost more than $100 per month (yeah, money is tight) Needs to support up to 25 users We can host our own web applications, but it must be low maintenance solution

  • Can I make two wireless routers communicate using the wireless?

    - by Dana Robinson
    I want to make a setup like this: cable modem <-cable- wireless router 1 <-wireless- wireless router 2 in another room <-cables- PCs in another room Basically, I want to extend my network access across the house and then have a bunch of network jacks available for my office PCs. Right now, I have a cable modem going to a wireless router in one room and a PC with a wireless PCI card in it in the office on the other side of the house. I use internet connection sharing with the other PCs in the office. The problem is that ICS is flaky, especially when I switch to VPN on the Windows box to access files at work. I picked up a wireless USB adapter that I thought I could share among the PCs I work on but I'm not very happy with it so I'm going to return it (NDISwrapper support for it is poor). Is this possible? My wireless experience so far has been pretty straightforward so I have no idea what kind of hardware is available. I've looked at network extenders but those just look like repeaters for signal strength. I want wired network jacks in my office.

  • Windows DFS - file locking & replication?

    - by Adam Salkin
    I'm in a small company that has offices on the east and west coasts of America and also various people working from their homes. There are Windows Servers already in the offices. I think that Microsoft Windows DFS will do what I want, but despite reading the web site, I'm really not sure, so I'm hoping that someone can confirm if it will do all the following: (For various personnel / political reasons I know that a proposal for a Microsoft Windows system has more chance of being accepted than any *nix system) Creation of a Folder so that any files in this folder will automatically be available on the servers in all the offices. When anyone opens up one of these shared files on any of servers, the copies on all the servers will automatically be locked. And when they close the file, the updates automatically get copied to the file on all the servers. VPN access to these folders for people working outside the offices. Bandwidth at the main offices varies from 6 Mb/s to 20Mb/s. Files are Excel / Word / AutoCAD ranging in size from 100KB to 4MB. Thank you.

  • What's the best way to telnet from a remote Windows PC without using RDP?

    - by Rob D.
    Three Networks: 10.1.1.0 - Mine 172.1.1.0 - My Branch Office 172.2.2.0 - My Branch Office's VOIP VLAN. My PC is on 10.1.1.0. I need to telnet into a Cisco router on 172.2.2.0. The 10.1.1.0 network has no routes to 172.2.2.0, but a VPN connects 10.1.1.0 to 172.1.1.0. Traffic on 172.1.1.0 can route to 172.2.2.0. All PCs on 172.1.1.0 are running Windows XP. Without disrupting anyone using those PCs, I want to open a telnet session from one of those PCs to the router on 172.2.2.0. I've tried the following: psexec.exe \\branchpc telnet 172.2.2.1 psexec.exe \\branchpc cmd.exe telnet 172.2.2.1 psexec.exe \\branchpc -c plink -telnet 172.2.2.1 Methods 1 and 2 both failed because telnet.exe is not usable over psexec. Method 3 actually succeeded in creating the connection, but I cannot login because the session registers my carriage return twice. My password is always blank because at the "Username:" prompt I'm effectively typing: Routeruser[ENTER][ENTER] It's probably time to deploy WinRM... Does anyone know of any other alternatives? Does anyone know how I can fix plink.exe so it only receives one carriage return when I use it over psexec?

  • sql developer cannot establish connection to oracle db with listener running

    - by lostinthebits
    I am working from home and connected to my work's vpn. I have tried to connect to the work db with sql developer (the latest version and the previous version) on the following environments: mac os x 10.8.5 (with sql developer launched and installed directly on the iMac. sql developer launched and installed directly on a vm on same computer (guest Ubuntu 12.04 LTS) sql developer launched and installed directly on a vm on same computer (guest Windows 7.0 Professional) I get Status Failure Test Failed : IO Error - The Network Adapter could not establish the connection. I have read dba forums and googled and the most common suggestion is that the oracle listener is not up and running. I can conclusively say this is not the case because I have the option of using remote desktop and accessing the oracle db in question on my work computer. If the listener was down, according to my DBA, no one would be able to connect. My sysadmin and dba are stumped so I assume it is something unique to my home system. The reason I do not want to continue with the remote desktop workaround is because remote desktop has an annoying (infuriating often) lag.

  • How to setup equivalent USVIDEO.ORG DNS-Proxy on Linux

    - by Gary
    I have a VPS in the USA running Ubuntu. I want to setup something similar to http://www.usvideo.org Basically, USVIDEO is a DNS service that allows Canadians to access American content like Hulu, Netflix, NBC, and etc (restricted by geographical IP). Here is how I think USVideo does it: Clients (PS3, XBOX, PC) specifies the DNS server(s) as specified on USVIDEO.org's website. If the DNS request is a video/audio site such as Netflix or Pandora, forward the request to a proxy. Otherwise, for all other requests, forward it to a different DNS server. If the specific video/audio URL is requested, return the address of the proxy server, which in turn relays traffic to the destination video/audio domain via the U.S. gateway so that it appears that the access is coming from a U.S. IP address. Once the DNS request has passed the U.S. IP address check, their proxy server steps out of the loop and lets the video streaming site contact you directly to start the video stream. This trick relies on the way that the video streaming sites check the country of your IP address once up front, but don't actually check the country of the destination IP address while the video is streaming. What is elegant about this solution is that a VPN Tunnel is not required to bypass geographical IP checks from certain websites. All that is required on the client side is to specify the DNS server (the VPS). If a certain site is geographically locked, just forward the traffic to a proxy, and that's it. These sites can be specified in the DNS entries, or perhaps in the proxy service to redirect the DNS request to its own proxy. I believe what I need to setup something similar is Squid Proxy, IPTables, and DNS. What I need help is how to exactly approach this? Would Squid Proxy be setup as a transparent proxy?

  • How do I keep folders synced and backed up between two macs using a Linux NAS (rsync?)

    I've got two primary computers, one Mac Pro and one MacBook Pro for when I'm on the go. I've also got a Linux sever which also acts as NAS. Currently I backup the entire computers to an external drive with Time Machine which is rather useless and doesn't sync anything. What I really want to do is to keep my important files synced between both computers and my NAS (which is running RAID 5), that way I'm not backing up easily replaceable systemfiles and I've got all my important files in 3 places where two of them are running raid so at least 5 drives would have to crash at the same time before actual data loss occur. Folders I want to keep synced is basically my photo, documents, development, mamp and work folders and then I want to keep the user library folder backed up but not synced. I'm thinking that I'd have to use rsync but don't know how. Before suggesting Dropbox and similar suggestions I don't want to use them because of several reasons some of them being security (Dropbox obviously proved this), Speed (sometimes I'll sync gigabytes of data and that will be significantly faster locally and probably even through VPN as I have a Gigabit pipe), Space (space on my NAS is cheap and only practically limited by my needs), reliability (even if my internet were to go down I still need to be able to keep my files synced incase I'd need to go somewhere on the fly), price (I already have all the hardware and for the amount of gigabytes and bandwidth I'd need I doubt that there's any free or cheap service). Those are my main reason for wanting to keep it locally. I'm sorry for any spelling or grammatical mistakes that I've might have done. I'm writing this on my smartphone from a shaky train and English isn't my mother tongue. I gratefully appreciate any answers even if only partly solving my problem.

  • route propogation using OSPF in a network

    - by liv2hak
    I am using Juniper J-series routers to emulate a small telco and VPN customer.The internal routing will be configured with OSPF,MPLS including a default and backup path,RSVP for distributing labels withing the telco,OSPF for distributing routes from the customer edge (CE) routers to the VRF's in the adjacent PE's and finally iBGP for distributing customer routes between VRF's in different PEs. The topology of the network is shown below. The Addressing scheme for the network is as follows. UOW-TAU ******* ge-0/0/0 192.168.3.1 TAU-PE1 ******* ge-0/0/0 10.0.1.0 ge-0/0/1 10.0.2.0 ge-0/0/2 192.168.3.2 TAU-P1 ****** ge-0/0/0 172.16.1.0 ge-0/0/1 172.16.3.1 ge-0/0/2 10.0.2.2 HAM-P1 ****** ge-0/0/0 172.16.3.2 ge-0/0/1 172.16.2.1 ge-0/0/3 10.0.3.2 ACK-P1 ****** ge-0/0/0 172.16.1.2 ge-0/0/2 172.16.2.2 ge-0/0/3 10.0.1.2 HAM-PE1 ******* ge-0/0/0 10.0.3.1 ge-0/0/2 192.168.4.2 UOW-HAM ******* ge-0/0/0 192.168.4.1 I also set up loopback address for each node. I want to setup OSPF so that path to each internal subnet and router loopback address is propogated to all PE and P nodes.I also want to select a single area for PE and P nodes,and on each node I should add each interface that should be propogated. How do I accomplish this.? With my understanding below is the procedure to achieve this.Is the below explanation correct? I set up OSPF on UOW-TAU ge-0/0/0 interface and ge-0/0/1 interface and UOW-HAM ge-0/0/0 interface and ge-0/0/1 interface. let me call this Area 100. Once I have done this I should be able to reach each node from others using ping and traceroute. Any help is highly appreciated.

  • How to connect the virtual networks of vmware guests running on different hosts?

    - by gyrolf
    In a test setup, we are running several virtual machines on a single vmware workstation host. All virtual machines are connected via a "host only" network. This runs fine up to 2 or 3 virtual machines (depending on the host hardware). To allow more virtual machines, we want to use more host machines. Details about the environment and applications: Host PCs are running Windows XP in a corporate intranet. VMware used is Workstation 6.5 Guests are running Windows Server 2003 All guests act as Web Servers One of the guests additionally acts as Windows File server, offering shared folders for the other guests to connect to. Restrictions: VMware guests shall not be visible from the intranet. Changes to the host PC are restricted by corporate policy. In the virtual network, no domain controller exists. All virtual machines are member of the same workgroup. Running the virtual network as NAT is possible. Port forwarding might be used if it does not conflict with ports used by the host PC. Looking for a solution, I found hints about using router or vpn software on the hosts, but without any details how to setup. (I found a similar question Sharing the network between 2 VMware hosts, but the answer was not sufficient for me.)

  • Windows 2003 Active Directory Integrated DNS zone not registering non-domain computers

    - by Jeff Willener
    I'm not a networking guy by all means, I'm just a developer who dabbles enough to get into trouble and I'm there. So bear with me... :) At my office I have a Windows 2003 Domain Controller which also services DNS. On the domain I have a handful of computers and other misc. equipment/toys. For the DNS I only created a Forward Lookup Zone for my domain (mydomain.com). I run a lot of VM's so generally I have everything on the domain, however some of those VM's are not and only in a 'Workgroup'. I also have another laptop which belongs to another domain (otherdomain.com) which is here 100% but I use it for other purposes and has to belong to the otherdomain.com. With all that said, I have two questions: I have found any computer not on mydomain.com does not register it's IP address even though 'Register this connections address in DNS' is set to in the 'Advanced TCP/IP Settings' for the nic. Where have I messed this up? On the laptop which is registered on otherdomain.com, when I do a nslookup for a computer on mydomain.com (e.g. nslookup devbox1) it appends otherdomain.com as the suffix (e.g. queries devbox1.otherdomain.com). Same thing occurs if I use the fully qualified name. In the 'Advanced TCP/IP Settings' for that nic, I can 'Append these DNS suffixes' of mydomain.com but I fear that will hose my DNS lookups when I VPN to otherdomain.com. So what is the correct approach to resolve this issue? Do I add both mydomain.com and otherdomain.com in that order?

  • Linux machine can't find its tape drive

    - by Kyle Hodgson
    I have an older HP NetServer LPr with what is apparently a Symbios SCSI card connecting to a Quantum SuperLoader 3 that is DLT based. From time to time, we seem to lose the connection to the autoloader. It's usually due to flaky power, but not totally sure why; sometimes when this happens the Autoloader's LED's are orange and it needs to be power cycled. The annoying workaround currently is to reboot the machine. As it is our production VPN and DNS server in addition to being our backup server, this is less than optimal. In Debian (Sarge) is there not some command one can type to get the card to notice that it has the autoloader connected again? dcr1:/proc# grep -i symbios /proc/pci SCSI storage controller: LSI Logic / Symbios Logic 53c895 (rev 1). dcr1:/proc# uname -a Linux dcr1 2.4.27-3-686 #1 Tue Dec 5 21:03:54 UTC 2006 i686 GNU/Linux dcr1:/proc# mt status mt: /dev/tape: No such device dcr1:/proc# ls -l /dev/tape lrwxrwxrwx 1 root root 8 2007-02-07 16:01 /dev/tape -> /dev/st0 dcr1:/proc# That mt status command will show the actual st0 status when things are working correctly. The No such device message is usually the second clue that we need to reboot - the first clue is usually that the backups didn't run.

  • How can I "share" a network share over the internet to multiple operating systems?

    - by Minsc
    Hello all, We have a network share accessible through our intranet that is widely used. This share has it's own set of fine tuned permissions. I have been tasked with allowing A.D. authenticated access to this share over the internet without the use of VPN. The internet access has to mimic the NTSF permissions in place on the share. Another piece of the puzzle is that the access over the internet has to allow perusal of the share from Windows and Mac OS systems. I had envisioned a web front end that would facilitate downloading to and uploading from the share via a web browser. I'm trying to ask for some suggestions about what type of setup is necessary to achieve this. I've done loads of testing and searching for solutions but I can't seem to get anything to work as I hope. The web server that will be handing all of this is a Windows 2K8 box with IIS 7. How can I allow the users to authenticate against Active Directory when coming from the internet even when coming from a Mac system? I hope my question is not too broad, I'm sorry if I should have broken it up into multiple questions. It all is just tied together in my head. Thank you all for your time and aid.

  • Login to OS X Server User Account from Local Computer

    - by Brod Wilkinson
    I have OS X Server installed on a mac mini. I've created several User accounts, one of which is Account Name: Bob Password: abc123 From the Mac Mini's login screen I can choose "Server" (main account) "Bob" (Bobs account) and "Other..." OS X Server Accounts, from "Other..." if I input Bobs credentials it will log me in. I also have a macbook air, I would like to be able to select from the Login Screen "Other..." input Bobs credentials and have it login to Bobs account, or any other User Account for that matter. My Server is setup as private with the server address: server.network.private Following some googled instructions as well as apples very own instructions I have: Setup an Open Directory with Username: diradmin Password: abc123 Then on the macbook air gone into System Preferences > Users & Groups > Login Options and clicked Join next to Network Account Server, input my server (server.network.private) with diradmin credentials and its connected. Great. I've also ticked Allow Network Users to Login and Login Window and selected All Users. I was assuming this would allow my macbook air to login to the "Bob" account by selecting "Other..." from the login window although there is no "Other..." option. I then setup a VPN, basic credentials, logged into it on the macbook air and still not much has changed. I am able to share screens with the "Bob" account form my macbook air by logging in by clicking Share Screen... from the Finder under Shared > Network Server and then clicking Login In but this obviously requires the macbook air to already be logged into an account before it can share screens which is not suitable. Is there any way to simply login to the OS X Server User Account from the macbook air's login screen via the "Other..." like it does on the mac mini's login screen? Thanks in advance. Operating System: OS X 10.9 Mavericks OS X Server: Version 3
