  • How to fill in the network line in the ubuntu interfaces config file?

    - by matnagel
    I have to configure an ubuntu hardy server network interface. The service hoster told me that this is the network data for the machine: IP Range: 111.111.200.74 to 111.111.200.78 Netmask: 255.255.255.248 Broadcast: 111.111.200.79 Gateway: 111.111.200.73 Subnet: 111.111.200.72/29 I am only using the first IP address. I will update the /etc/hosts file with 111.111.200.74, but I am still unsure how the /etc/network/interfaces file should be. This is my plan: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 111.111.200.74 netmask 255.255.255.248 network 111.111.200.??? broadcast 111.111.200.79 gateway 111.111.200.73 As you can see I don't know how to build the network line. How would I calculate the data for the network line and what is the result? (I changed the first 2 octets of the subnet, they are not "111.111" in the real setup.)

  • Is it possible to add an existing Azure VM to an Azure Virtual Network?

    - by Dan Harris
    Didn't think this was directly related to programming, so thought Superuser would be better than Stack Overflow.... Is it possible to add an existing Azure VM to an Azure Virtual Network if you didn't add it to the virtual network at the time of creation? I can't see an option to change which Virtual Network the VM is connected to. Do you just have to do it at the time you create the VM, and if you don't do it then you will need to re-create the VM and delete the existing one? Example of the scenario: No VM's or Virtual Networks exist I create a VM (VM1), there is no virtual network so it isn't added to one Later I create a Virtual Network in Azure (Network1) It is possible to create another VM (VM2) and connect it to the Virtual Network (Network1), but can I connect VM1 to Network1 or must I delete VM1 and re-create it to get it connected to Network1?

  • Finding Locked Out Users

    - by Bart Silverstrim
    Active Directory up to 2008 network (our servers are a mix of 2008, 2003...) I'm looking for a quick way to query AD to find out what users are locked out, preferably from a batch or script file, to monitor for possible issues with either user accounts being attacked by an automated attack or just anomalies in the network. I've Googled and my Google-fu has failed; I found a query off Microsoft's own knowledgebase that cites a string to use on Server 2003 with the management snap-in's saved queries (http://support.microsoft.com/kb/555131) but when I entered it, the query returned 400 users that a spot-check showed did NOT have a checkmark in the "Account is locked out" box under "account." In fact, I don't see anything wrong with their accounts. Is there a simple utility (wisesoft bulkadusers apparently uses this method behind the scenes, since it's results were also wrong) that will give a count of users and possibly their user object names? Script? Something?

  • Cross-platform centralized desktop password manager

    - by Dave
    I have been using KeePass as a desktop password manager on Windows for many years. Love it! However, I am now needing to work on different platforms much of my day (Windows 7, Windows XP, Mac OS X, Ubuntu, and OpenSUSE.) I'm looking for a password manager I can share across all these platforms. My ideal solution would: Run natively (not in a virtual machine) on all platforms. Store the "official" copy of the password data on a local network so I can get to it from any and all machines. It is OK if it locks (or becomes read-only) when one client is accessing it. Keep a local cached copy (read-only is fine) so I can still get to my passwords when disconnected from the network. Does any such beast exist?

  • Two Network Adapters on Hyper-V Host - Best way to configure?

    - by GoNorthWest
    I have two physical network adapters installed in my Hyper-V host. I want one to be dedicated to the host, and the other to provide external network services to the VMs. Would the appropriate configuration be as such: Leave the first physical network adapter alone, assigning it the host IP, but not using it to create any Virtual Netorks For the second physical adapter, I would create an External Network, along with a Microsoft Virtual Switch, and use that to provide network services to the VMs. Each virtual NIC for the VM would be associated with that External Network. A static IP would be assigned to this adapter, and each VM would be assigned a static IP as well. The above seems reasonable to me, but I'm not sure if it's correct. Does anyone have any thoughts? Thanks! Mark

  • Why can a network address not be a valid host address?

    - by Goblinlord
    So... I have studied for CCNA and such and been working with IP networking at the least the past 8 years or so. I have always seen and been told that the network address for a subnet is not a valid host address. Now first I will start by saying I know this is true. My question is more... is there a technical reason it can not be used or was it just arbitrarily agreed upon when the specification was designed? I understand why a broadcast address can not be used (because it is ACTUALLY used). The thing is when I see a network address used it is normally only in routing which is specifically using NETWORK addresses. This being the case, (network addresses being used only when you are expecting a network address) is there some technical reason that they could not have the network address be an actual valid host address?

  • Are there open source alternatives to Bitbucket, Github, Kiln, and similar DVCS browsing and management tools?

    - by Ryan Taylor
    I am aware of several tools/services that provide DVCS browsing and management such as Bitbucket, Github, Kiln, SCM-Manager and Rhodecode. However, the use case I am considering is one such that: Any source code must reside on an employers internal servers. The solution must be open source. It should provide a Bitbucket or Github like experience, including a project wiki, repository browsing and management, and social coding aspects such as code review. The solution should have mercurial support (if not support for other DVCSs). Of these, only SCM-Manager and RhodeCode come close as they can be installed on your own servers and are open source. However they do not have the Bitbucket or Github experience. There is no issue tracker or wiki and the UI, while functional, is not up to par with Github or Bitbucket. I can get close with Trac or Redmine with their repository browsers but unfortunately they do not have any repository management capabilities. Are there other open source tools out there that would provide a similar experience to Bitbucket, Github or Kiln?

  • Is it wise for a programmer to move into management?

    - by Desolate Planet
    Many times, a developer has suggested that I become a team leader because I'm motivated, but during my career in the IT industry, I've seen so many people who are great at programming, move into management and they are miserable. I've also seen many managers return to programming stating "I'm a technical person, I like technical problems". If this is such a common thing, why do developers feel compelled to leave the technical domain and move into management? Sure you'll have more money and more control, but if you don't enjoy your work and take your problems out on your tream. Secondly, I've been asked in developer interviews, "Would you consider leading a team?" and I'm always tempted to cite the Peter Principle based on what I've seen. I am interested in furthering myself, but not in the way the company may want i.e "Vice President of department blah". To be honest, I've seen this more often in the corporate world than in small development houses and it's always put me off ever going back to a corporate environment. I just feel that this is becoming more and more the norm and it's impacting team morale and degrading the quality of the work. Question: Based on what I've said, Is it a smart move for a technical person to move into management?

  • In C++ Good reasons for NOT using symmetrical memory management (i.e. new and delete)

    - by Jim G
    I try to learn C++ and programming in general. Currently I am studying open source with help of UML. Learning is my hobby and great one too. My understanding of memory allocation in C++ is that it should be symmetrical. A class is responsible for its resources. If memory is allocated using new it should be returned using delete in the same class. It is like in a library you, the class, are responsibility for the books you have borrowed and you return them then you are done. This, in my mind, makes sense. It makes memory management more manageable so to speak. So far so good. The problem is that this is not how it works in the real world. In Qt for instance, you create QtObjects with new and then hand over the ownership of the object to Qt. In other words you create QtObjects and Qt destroys them for you. Thus unsymmetrical memory management. Obviously the people behind Qt must have a good reason for doing this. It must be beneficial in some kind of way, My questions is: What is the problem with Bjarne Stroustrups idea about a symmetrical memory management contained within a class? What do you gain by splitting new and delete so you create an object and destroy it in different classes like you do in Qt. Is it common to split new and delete and why in such case, in other projects not involving Qt? Thanks for any help shedding light on this mystery!

  • Accessing original WordPress blog's DB from sub-blogs in network mode

    - by aendrew
    I'm helping with a university radio station website that runs WordPress and was recently switched over to Network (Multi-site/multi-user) mode by myself. The setup is as such: The parent site (www.stationID.com) runs a bunch of custom-built plugins to construct things like the show schedule calendar, the "Now Playing" widget, podcast list, et cetera. The new network websites ("wiki.stationID.com", "buddypress.stationID.com" for instance) run the same template as the parent site, but it stops after rendering the first section because the widgets from point 1 grab data from the main site's database that is not available to sub-blogs. My question is: how do I get data from the main site's tables on the sub-domain sub-blogs? A related question is: how do I set the $wpdb->prefix to be the same as the parent site on the child websites without it negatively effecting how the child website pulls data from its own database? Any help would be awesome, thanks!

  • Asynchronous callback for network in Objective-C Iphone

    - by vodkhang
    I am working with network request - response in Objective-C. There is something with asynchronous model that I don't understand. In summary, I have a view that will show my statuses from 2 social networks: Twitter and Facebook. When I clicked refresh, it will call a model manager. That model manager will call 2 service helpers to request for latest items. When 2 service helpers receive data, it will pass back to model manager and this model will add all data into a sorted array. What I don't understand here is that : when response from social networks come back, how many threads will handle the response. From my understanding about multithreading and networking (in Java), there must have 2 threads handle 2 responses and those 2 threads will execute the code to add the responses to the array. So, it can have race condition and the program can go wrong right? Is it the correct working model of iphone objective-C? Or they do it in a different way that it will never have race condition and we don't have to care about locking, synchronize? Here is my example code: ModelManager.m - (void)updateMyItems:(NSArray *)items { self.helpers = [self authenticatedHelpersForAction:NCHelperActionGetMyItems]; for (id<NCHelper> helper in self.helpers) { [helper updateMyItems:items]; // NETWORK request here } } - (void)helper:(id <NCHelper>)helper didReturnItems:(NSArray *)items { [self helperDidFinishGettingMyItems:items callback:@selector(model:didGetMyItems:)]; break; } } // some private attributes int *_currentSocialNetworkItemsCount = 0; // to count the number of items of a social network - (void)helperDidFinishGettingMyItems:(NSArray *)items { for (Item *item in items) { _currentSocialNetworkItemsCount ++; } NSLog(@"count: %d", _currentSocialNetworkItemsCount); _currentSocialNetworkItemsCount = 0; } I want to ask if there is a case that the method helperDidFinishGettingMyItems is called concurrently. That means, for example, faceboook returns 10 items, twitter returns 10 items, will the output of count will ever be larger than 10? And if there is only one single thread, how can the thread finishes parsing 1 response and jump to the other response because, IMO, thread is only executed sequently, block of code by block of code

  • What is best way to raise application events for use with admin network monitoring tools

    - by J Cooper
    In a semi-critical .NET service application, what would be a good strategy for raising application events that could be monitored by network administration tools? The events would be for errors, status changes, and possibly other notifications. My company is planning to use some kind of tool down the road to monitor all critical machines and services. As of right now they are using Spice Works to do some monitoring but it is not known if they will keep this down the road. By strategy I mean, perhaps using some sort of protocol ( my network admin has mentioned SNMP), perhaps a service such as windows event log. I have no idea what is available, so I'm leaving the options open. With that in mind, here is a list of preferences I came up with: Somewhat easy to use with .NET. Reliability Should work well with a variety of admin monitoring tools Works with non - windows monitoring tools Works with Spice Works

  • Linux: page faults and network filesystems

    - by Alex B
    If a Linux system runs out of physical memory, does it drop inactive executable code pages? I assume the answer is yes, since there is no reason to keep them in swap, so they are simply discarded and re-loaded if necessary (as far as I know, that's what FreeBSD does). If the above is true for Linux, my question is, how does it handle executables run from network filesystems (e.g. NFS)? Does it go and fetch executable pages over the network if there is a page fault?

  • SQL Server database backup: Network Service file access

    - by Keith Maurino
    When trying to run the following database backup command from my code I get an "Operating system error 5(Access is denied.)" error. This is because the log on account for the SQL Server Windows Service is 'Network Service' and that does not have access to right to this folder. BACKUP DATABASE [AE3DB] TO DISK = 'c:\AE3\backup\AE3DB.bak' My question is, from my code how would I go about figuring out where on the C drive 'Network Service' is allowed to right the backup to? NOTE: This is a distributed application so I cannot easily change the log on for the SQL Server Windows Service to the 'Local System' account that would be able to right to that folder.

  • interesting network or git problem

    - by bogumbiker
    I have a setup my own git repository with gitosis on dedicated debian server. The server is visible via port 22 from outside (the port 22 is forwarded from my router to my git server). On the local network the git repository works perfectly. The problem happens once I try to do "git clone.." from remote server. So once I do "git clone.." from remote I am getting git clone hung after cloning around 20-30% of the repository (small around 2MB) and I think this is the random percentage. I can do scp to and from the git server without any problems. Also as I mentioned the git clone, push, etc works perfectly within my internal network. Any idea how to debug this problem? thanks

  • Amusing or Sad? Network Solutions

    - by dbasnett
    When I got sick my email ended up in every drug sellers email list. Some days I get over 200 emails selling everything from Viagra to Xanax. Either they don't know what my condition is or they are telling me you are a goner, might as well chill-ax and have a good time. In order to cut down on the mail being downloaded I thought I would add all of the Junk email senders from Outlook to my Network Solution mail server. Much to my amazement I could not find that import Spammers button, so I submitted a tech support request. Here is the response: Thank you for contacting Network Solutions Customer Service Department. We are committed to creating the best Customer experience possible. One of the first ways we can demonstrate our commitment to this goal is to quickly and efficiently handle your recent request. We apologize for any inconvenience this might have caused you. With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers. An alternative option is for you to create a Custom Filter that filters unwanted e-mails. To create a Custom Filter: Open a Web browser (e.g., Netscape, Microsoft Internet Explorer, etc.). Type mail.[domain name].[ext] in the address line. Login to your Network Solutions email account. Click on the Configuration left menu tab. Click on the Custom Filter link. Type the rule name. blah, blah, blah Basically add them one at a time. "We are committed to creating the best Customer experience possible." No you are not. You are trying to squeeze every nickle you can out of me. "With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers." Maybe I should apply for a job to write those ten complicated lines of code... Maybe I should question my choice of vendors, because if they truly "cannot" then they are to stupid to have my business. It is both amusing and sad. I'll be posting this in every forum I am a member of.

  • How can I programmatically find the IP address/netmask/gateway configured for a specific network dev

    - by Oren S
    Hi I would like to write a piece of code which checks, for each network device (e.g. eth0, lo, master devices) some statistics and configuration data about that device. I could find the statistics data (and most of the configuration data) in /sys/class/net/..., however, I couldn't find any C/C++ API or any entry in procfs/sysfs listing the inet addr, netmask and gateway. Some alternatives I checked: parsing the output from ifconfig/route/some other utilities: I don't want to start a subprocess every time I need to do the inspection. parsing /etc/sysconfig/network-scripts/: will give me only the start-up configuration, and not the current state. Also, since this code is intended for a product in my workplace, where every external library is inspected thoroughly (meaning it will take me forever to add any external library) I prefer solutions which rely on Linux native API and not external libraries. Thanks!

  • Deployment of broadband network

    - by sthustfo
    Hi all, My query is related to broadband network deployment. I have a DSL modem connection provided by my operator. Now the DSL modem has a built-in NAT and DHCP server, hence it allocates IP addresses to any client devices (laptops, PC, mobile) that connect to it. However, the DSL modem also gets a public IP address X that is provisioned by the operator. My question is Whether this IP address X provisioned by operator is an IP address that is directly on the public Internet? Is it likely (practical scenario) that my broadband operator will put in one more NAT+DHCP server and provide IP addresses to all the modems within his broadband network. In this case, the IP addresses allotted to the modem devices will not be directly on the public Internet. Thanks in advance.
