  • How to execute files on LAN drives in a Windows Domain

    - by matnagel
    We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

  • Black Hat Hackers vs Programmers?

    - by Matt Ridge
    This came up with another question I had here, I have decided on a programming verification system that requires a hardware verification system, a software key, and a name/password system. Now people are saying that hackers will bypass any new security, which may be true, but I have a few questions. There has to be a balance between programmers programming and hackers stealing software, otherwise programs wouldn’t be made, and we wouldn’t be where we are today. What is that balance? 5%, 10%, 20%, 50%? What is too much security for the end user? What is too little security so the hacker can just push through without issue? If your software becomes popular, what should you expect or accept as acceptable loss? Why should we accept black hat hackers as a way of life?

  • MAAS/JuJu Clarifications

    - by ectoskeleton
    I really love the concept of MAAS underlying an OpenStack implementation, but there are a few questions about MAAS that I am not entirely clear on. Should all hosts be set to network boot at all times or after they have been registered and allocated as a service, should they boot to disk? After juju bootstrap is executed, I turn on the machine that has been allocated (note WoL isn't working, I suspect it's being blocked on the network), the machine boot's up and then juju status executes correct, agent running and all that good stuff. If I 'reboot' the machine (testing power failure/problem whatever), juju status comes back but the agent-state is no longer in running state, and so far I have to destroy the environment and restart. In all cases I have never been able to deploy any services to any of the other nodes. I deploy the service with juju, note which node it was assigned, and then start the system. The system just boots up into a basic node. If I SSH to it I have to enter password, so it's not setting up the ssh key or anything. This is on Ubuntu 12.04.1 LTS systems and HP GL360G7 hosts. The MAAS management server is running as a VM but all on the same network. At this point I am not sure if I am doing something wrong or if there is a problem somewhere else. Is the idea that anytime a host is rebooted it should be rebuilt from the ground up, or is something else going on behind the scene to tell it to boot the local image. If the latter, why doesn't the agent start on a system that has been successfully setup before (juju bootstrapped system)?

  • Are there any books dedicated to writing test code? [on hold]

    - by joshin4colours
    There are many programming books dedicated to useful programming and engineering topics, like working with legacy code or particular languages. The best of these books become "standard" or "canonical" references for professional programmers. Are there any books like this (or that could be like this) for writing test code? I don't mean books about Test-Driven Development, nor do I mean books about writing good (clean) code in general. I'm looking for books that discuss test code specifically (unit-level, integration-level, UI-level, design patterns, code structures and organization, etc.)

  • Bridge 2 routers

    - by Nathan Adams
    I have 2 Linksys WRT54GL routers flashed with DD-WRT. On each I have a different ISP, and thus a different private network. I would like to be able to talk to either network regardless of what network I am on. Example: ISP1 - Router1 - Client ISP2 - Router2 - Client What I would like to do is something like: ISP1 - Router1 - Client              ^              |              v ISP2 - Router2 - Client This would be ideally because then I don't need to introduce another device in the mix, unless I have to. But I guess the first question is - is this even possible?

  • Reasons for either 32-bit or 64-bit as development machine

    - by vartec
    I'm about to make a new Linux install, which will be primarily used for programming. I've seen benchmarks showing speed improvement of 64-bit version, however, I have hard time of telling how much these benchmarks translate to improvement in every day usage. And of course there are other aspects to consider. Usage I have in mind: mainly programming Python, with occasional C, C++ and Java; IDEs, which are using Java platforms (Eclipse and IntelliJ); on very rare occasions having to compile for 32-bit platform; not planning to have more than 64GB of RAM anytime soon (and I don't mind using PAE kernels); machine in question has 4GB RAM and Athlon II X2; What are pros and cons of choosing either i386 or x86_64 distro?

  • How to configure bind9 to route to host's IP

    - by Greg
    I'm running apache and bind9 on the same server. I would like to set a master zone to route back to this very machine's IP address without explicitly specifying it. Is this possible? If I use 127.0.0.1 for the A record, then when another computer on the network does an nslookup for mydomain.local, bind of course just returns the loopback ip (127.0.0.1) -- not the IP of the server. Is there to way to tell it to just return the network IP address for the server itself, as defined in /etc/network/interfaces?

  • Two subnets on one switch with no VLAN and possible problems

    - by casey_miller
    As far as I know in order to use two subnets on one physical cable VLAN's are recommended. However, is it possible to achieve this (i.e: two subnets on one physical network) like 192.168.1.0/24 and 10.0.0.0/8 networks. What kind of problems or hidden rocks this way contains? With VLAN's it's possible to better isolate so users wouldn't easly sniff the other network. But in my environment it's okay if user on one subnet could listen to the traffic on another network. Is it the only problem?

  • Monitoring bandwidth/latency/jitter between 2 sites?

    - by TheCleaner
    I have 2 sites connected via an MPLS network and I'd like to do the following: setup a host on each end that can "talk" back and forth between each other and somehow report/log what kind of throughput, jitter, latency, etc. they are experiencing between each other in 5 minute intervals. Something similar to Qcheck but that can be automated. Bottom line is I'm trying to determine if the WAN network is "stable" throughout the day or if something is wrong. We have video conferences between these sites and even at 1024kbps calls we are experiencing delays and jitter. I'm hoping to exonerate the network with some testing.

  • Cannot authenticate to SBS 2003

    - by Lerp
    I am trying to connect my machine to my work's entirely windows network and I am having a few issues: Whenever I try to access the server, the authentication dialog just keeps popping back up. I cannot connect to the printers (it says connecting to device failed) I have tried setting up samba, winbind, kerberos, likewise open all to no avail. I have a feeling I am just setting them up wrong. My nautilus shows this when I go to Network Windows Network MASTERMAGNETS I can ping both MASTERMAGNETS.LOCAL and 192.168.0.2 after modifying my /etc/hosts james@jamesmaddison:~$ cat /etc/hosts 127.0.0.1 localhost jamesmaddison 192.168.0.2 MASTERMAGNETS.LOCAL 192.168.0.50 Sharp-Printer # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters I believe that's the correct domain (not sure if that's the correct term) as when I do nslookup MASTERMAGNETS.LOCAL I get the following: james@jamesmaddison:~$ nslookup MASTERMAGNETS.LOCAL Server: 192.168.0.2 Address: 192.168.0.2#53 Name: MASTERMAGNETS.LOCAL Address: 192.168.0.3 Name: MASTERMAGNETS.LOCAL Address: 192.168.0.2 It all worked fine before I reinstalled Ubuntu and now I just cannot get access to the server. All help is appreciated, I need to get this working or I fear I will be forced to develop in a windows environment :(

  • How to make sure Windows PC is reasonably secure?

    - by Coder
    I'm not much of a network and network security expert, but I need to add an existing Windows PC to a network with always on connection. The problem is, I have no idea if the PC is really clean, and, actually, no knowledge to check it. I scanned the PC with Process Explorer to verify if all running processes are signed, ran an AVG scan, but this is where my knowledge ends. IIRC, there can be bad code attached to svchost or something, bad drivers, and so on, but I have no idea how to check all those things. Reformatting the PC is unfeasible as of now. Are there any suggestions on what I could do?

  • Tips for a first year CS student looking for a summer internship to gain experience?

    - by Matt
    Hello all, I am a first year CS student and my programming experience is only what I have obtained in my computer programming I and II classes this school year. (console applications in C++) I want to find a summer job/internship that would help me build my skill set. Being that I am still such a beginner pay is not a concern, minimum wage would be nice, but as long as I am learning, I really don't care. My current resume just lists a bunch of random jobs i've had in the past (burger king, summer camps, best buy, etc.) Does anyone have any tips (places to look? things to put on resume?) that might help me?

  • Mikrotik server networks and Cain & Abel

    - by user269742
    I'm connected to the internet via a mikrotik server network. Recently, I read about that scaring application named Cain & Abel and all the capabilities it offered for malicious users. I don't know if anyone on my network is using or even aware of such application but my questions are: 1- How to protect myself from this program? 2- How to know if someone using such application against me? 3- Is Tor Bundle capable of protecting me from Cain & Abel? 4- If I filled my e-mail password via SSL page, Can Cain & Abel collect it? 5- Is it safe to use SKYPE or Yahoo Messenger voice chat if some one using Cain & Abel on my network?

  • Default gateway is in different subnet. How to configure in RHEL6.2

    - by Dmytro Leonenko
    I have two subnets routed to my server from ISP. I have only one gateway ip. The gateway is on the same VLAN as my IP address. For example netowrk 1 is 1.0.0.0/24 and network 2 is 2.0.0.0/24. Both are routed to eth0 by my ISP. Gateway is 1.0.0.1. My host ip is 2.0.0.1/24 (eth0) So I can configure default gateway manually with ip route add default dev eth0 ip route add default via 1.0.0.1 and then internet connection works properly. How do I configure it in /etc/sysconfig/network-scripts/ifcfg-eth0 ? I tried to set GATEWAY=1.0.0.1 but it doesn't work. Tried to set GATEWAY and GATEWAYDEV in /etc/sysconfig/network and it does only what first command from listing above do.

  • Configure Windows Routes for VPN

    - by Florin Sabau
    I have a Virtual PC/VMWare machine that runs Windows Server 2003. This virtual machine uses an IPSec VPN client program to connect to a remote network. I configured the virtual machine to have 2 NICs: NAT - to be used by the VPN Client to access the remote network Host only - to be able to access the virtual machine from the host The reason I have this setup is because I want to be able to access some remote network from the host machine. I could've installed the VPN client on the host machine, but the host runs Windows 7 and the client doesn't support it. The problem: although the virtual machine is normally reachable (ping + http access), as soon as the VPN client is started, neither of the NIC addresses are reachable anymore. I'm wondering if it is a routing problem that needs to be addressed? How do routing/VPN client connection affect the ability of the server to respond to client requests from the host?

  • Automatically updating routing table on server

    - by bramp
    I have a LAN with three routers on it, one connected to the Internet, one VPN router connected to a few remote sites, and a final route connected to a private network (using BGP to get prefix advertisements). On the same LAN I have multiple Linux servers which needs access to the networks behind each router. I have achieved this by configuring static routes on the server, pointing the different network prefixes to the correct router. This has worked well, but every time we connect to a new remote VPN, we have to change all the servers to be aware that the network is now accessible via the VPN, and not via the default Internet route. What I want is a way to automatically update the routes on all of the servers, when the route is added to a routers. Now, I could install Quagga or something similar on all the servers to receive router advertisements, but that seems like overkill. So my question is what is the easiest/simpliest way to update the routing tables on the server automatically, and what protocol is best suited for this purpose. thanks

  • Cisco, How to do a subnetting scheme using VLSM and RIP-2?

    - by Andrei T. Ursan
    I'm studying for my CCNA exam and I have to create a VLSM scheme using RIP-2 for the following requirements: (this is an exercise) Use the class C network 192.168.1.0 network for your point-to-point connections Using the Class A network 10.0.0.0, plan for the following number of hosts in each location: New York: 1000 Chicago: 500 Los Angeles: 1000 On the LAN and point-to-point connections, select subnet masks that use the smallest ranges of IP addresses possible given the above requirements. In all cases, use the lowest possible subnet numbers. Subnet zero is allowed. My guess is the following: New York: S0/0 192.168.1.1 /24 Fa0/0 10.1.0.1 netmask 255.255.248.0 - because we need 1000 hosts Chicago: S0/0 192.168.1.2 /24 Fa0/0 10.2.0.1 netmask 255.255.252.0 (for 500 hosts) Los Angeles: S0/0 192.168.2.3 /24 Fa0/0 10.3.0.1 netmask 255.255.248.0 (for 1000 hosts) Is this a good configuration? I'm reading the CCNA book but not everything is very clear, so I said to do some exercises... Thank you!

  • How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

    - by David Siegel
    How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

  • What can programmers learn from the construction industry?

    - by Renesis
    When talking with colleagues about software design and development principles, I've noticed one of the most common sources for analogies is the construction industry. We build software and we consider the design and structure to be the architecture. One of the best ways to learn (or teach) are through analyzing analogies - what other analogies can be drawn from construction? (whether already in common use in software or not). Please provide a description, or your personal experience, regarding how the programming concept is similar to the construction concept. [Credit to Programming concepts taken from the arts and humanities for the idea]

    After a year programming a web based business management system, I got my idea divided into two differents ways to do what I'm doing...

Second Situation The same as before but with one big difference, everything (environment) is installed in the customer, then I need to cryptography all my codes (It includes PHP and Shell Scripts). I think this situation is most difficulty, but I would like to hear it from different points of view.

  • How to set-up a simple subversion workflow

    - by Milen Bilyanov
    I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.
