  • Resizing an existing linux partition during Ubuntu install

    - by Richard100
    Hello All, I have Fedora Core 10 installed on a PC, occupying the whole disk (no free space). I want to add Ubuntu 10.04 desktop edition. Does Ubuntu 10.04 allow you to resize existing partitions during the installation process in order to free up some space for the Ubuntu installation? Without losing or trashing existing data, obviously. Thanks.

  • ESXi 4.1 host not recognising existing VMFS datastore

    - by Graeme Donaldson
    Existing setup: host1 and host2, ESX 4.0, 2 HBAs each. lun1 and lun2, 2 LUNs belonging to the same RAID set (my terminology might be sketchy here). This has been working just fine all along. I added host3, ESXi 4.1, 2 HBAs. If I view Configuration / Storage Adapters, I can see that both HBAs see both LUNs, but if I view Configuration / Storage, I only see 1 datastore. host1/2 can see both LUNs and I have VMs running on both too. I have rescanned, refreshed and even rebooted, but host3 refuses to acknowledge 1 of the datastores. Does anyone know what's going on? Update: I re-installed the host with ESX (not i) 4.0, same version as the existing hosts and it's still not recognising the vmfs. I think I'm going to SVmotion everything off that datastore then format it. Update2: I've created the LUN from scratch and the problem gets even weirder. I've presented the LUN to all 3 hosts, and I can see the LUN in the vSphere client's Configuration / Storage Adapters section on all 3 hosts. If I create a datastore on the LUN via the Configuration / Storage section on host1, it works fine and I can create an empty folder via datastore browser, but the datastore is not seen by the host2 and host3. I can use the Add Storage wizard on host2 and it will see the LUN. At this point the "VMFS Label" column has the label I gave with "(head)" appended. If I try the Add Storage wizard's "Keep the existing signature" option, it fails with an error "Cannot change the host configuration." and a dialog box that says 'Call "HostStorageSystem.ResolveMultipleUnresolvedVmfsVolumes" for object "storageSystem-17" on vCenter Server "vcenter.company.local" failed.' If I try the Add Storage wizard's "Assign a new signature" option on host2, it will complete and the VMFS label will have "snap-(hexnumber)-" prepended. At this point its also visible on host3, but not host1. I have a similar setup in a different datacenter which didn't give me all this trouble.

  • Change the default route without affecting existing TCP connections

    - by Patrick Horn
    Let's say I have two public network addresses on my server: one NAT through an ISP (192.168.99.0/24), and a VPN through a different ISP (192.168.1.0/24), already configured with a per-host route to the VPN server through my ISP. Here is my initial routing table. I am currently routing through my ISP on subnet 192.168.99.0/24. $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.99.1 0.0.0.0 UG 0 0 0 eth1 55.66.77.88 192.168.99.1 255.255.255.255 UGH 0 0 0 eth1 192.168.99.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 Now, I want new TCP connections to switch to my 192.168.1.0/24 so I type the following: $ route add -net 0.0.0.0 gw 192.168.1.1 dev tap0 When I do this, it causes some long-standing TCP connections to hang. Is there a way to I safely change the default interface for new connections, while allowing existing TCP connections to use the old route (i.e. do I need enable some sort of stateful routing table)? I am okay with a solution that only works with established TCP connections, and I don't care how hacky it is. For example, if there is a way to add temporary iptables rules for existing connections to force them over the old route. But there has to be some way to do this. EDIT: Just a note about a simple "route add -host ... " for existing connections: this solution would work if I am fine with leaving a subset of IPs on the old interface. However, in my application, this actually doesn't solve my problem because I want to allow new connections to come on the new interface even if they have the same source IP. I'm now looking at using the "ip route" command to set source-based routing rules.

  • Cannot create a new domain in an existing active directory forest

    - by Mackenzie Carr
    I have a domain controller setup on Windows Server 2008 R2 (Forest) and I have another Windows Server 2008 R2 (New Domain) and I want to create a new domain in an existing forest. I get the following error: An Active Directory domain controller for the domain mackdev.mackenziecarr.com could not be contacted The error was "no records found for the given DNS query" The query was for the SRV record for: _ldap._tcp.dc._msdcs.mackdev.mackenziecarr.com I've seem to have tried everything even tried adding this record to the DNS server of the primary forest. I even successfully joined this server to the domain without any issues but trying to create a new domain under the existing forest is no luck. The primary forest I.P. address is 192.168.2.20 the server that I am using to try to make a child domain is 192.168.2.21 My ipconfig are as follows: I.P. Address: 192.168.2.21 Subnetmask: 255.255.255.0 Gateway: 192.168.2.1 Primary DNS: 192.168.2.20

  • Adding text over existing PDFs using reportlab

    - by Shane
    I'm interested in filling out existing PDF forms programatically. All I really need to do is pull information from user input and then place the appropriate text over an existing PDF in the appropriate locations. I can already do this with reportlab by feeding the same sheet of paper into a printer, twice, but this just really rubs me the wrong way. I'm tempted to just personally reverse engineer each existing PDF and draw every line and character myself before adding the user-inputted text, but I wanted to check to see if there was an easy way to take an existing PDF and set it as a background for some extra text. I'd really prefer to use python as it's the only language I feel comfortable with. I also realize that I could just scan the document itself and use the resulting raster image as a background, but I would prefer the precision of vector graphics. It seems like ReportLab has a commercial product with this functionality, and the specific function I'm looking for is in it (copyPages) - but it seems like overkill to pay for a 4 figure product for a single, simple function for a nonprofit use.

  • AWS Autoscaling issue with existing nodes in ELB

    - by Ram Prasad
    I already have a ELB setup called MyLoadBalancer. I already have 2 nodes running on it with health checks (that checks a URL on the node to see if they are up) Created an autoscaling group (min 2, Max 10) Associated launchconfig mylaunchconfig that provisions a node using an AMI Created a trigger, that checks for avg min connections of 100 and Max of 500 (checks the load balancer and it is support to increase the node count by 1, if avg connections are 500 and decrease by one if less than 100) as-create-or-update-trigger MyTrigger --auto-scaling-group MyAutoScalingGroup --namespace "AWS/ELB" --measure RequestCount --statistic Average --dimensions "LoadBalancerName=MyLoadBalancer" --period 60 --lower-threshold 500 --upper-threshold 800 --lower-breach-increment=-1 --upper-breach-increment=1 --breach-duration 600 Now the issue is, as soon as I put in the trigger, it start 2 nodes .... but there are already two nodes in the LB. So, why is it provisioning 2 more nodes, when the nodes are there ? is it because it is not recognizing the existing 2 nodes ? then how do I add the existing nodes to the AutoScaling group ?

  • CentOS Default ACLs on Existing File System Objects

    - by macinjosh
    Is there a way to have existing file system objects inherit newly set default ACL settings of their parent directories? The reason I need to do this is that I have an user who connect via SFTP to my server. They are able to change directories in their FTP client and see the root folder and the rest of the server. They don't have permissions to change or edit anything but their own user directory but I would like to prevent them from even view the contents of other directories. Is there a better way to do this than ACLs? If ACLs are the way to go I'm assuming a default ACL on the root directory would be the best way to do restrict access. I could then selectively give the user permission to view certain directories. The problem is default ACLs are only inherited by new file system objects and not existing ones.

  • Windows Phone 7: Existing Libraries Not Supported?

    - by Peterdk
    I was hoping it was as easy as referencing my existing libraries to use them with WP7. However, it complains about not able to load them because of .Net CF when I actually use them. Do i need to recompile them to .NET CF or something? I thought the big plus of WP7 was: leveraging your existing codebase...? How can I leverage my existing codebase if I need to strip everything out of it and maintain multiple versions?

    Here is the situation. I connected my iPad to some new PC, Synced, then ticking Sync Apps from Devices-Apps will give me warning that all existing apps on my iPad will be replaced with those from Library-Apps. But in Library I have just couple old apps, which long time ago I used. So how I can sync the library in iTunes with my existing apps from iPad? EDIT: I have tried to click on Transfer Purchases, but not all of the items went to the library, just few of them.

  • "select * into table" Will it work for inserting data into existing table

    - by Shantanu Gupta
    I am trying to insert data from one of my existing table into another existing table. Is it possible to insert data into any existing table using select * into query. I think it can be done using union but in that case i need to record all data of my existing table into temporary table, then drop that table and finally than apply union to insert all records into same table eg. select * into #tblExisting from tblExisting drop table tblExisting select * into tblExisting from #tblExisting union tblActualData Here tblExisting is the table where I actually want to store all data tblActualData is the table from where data is to be appended to tblExisting. Is it right method. Do we have some other alternative ?

  • Uniquing with Existing Core Data Entities

    - by warrenm
    I'm using Core Data to store a lot (1000s) of items. A pair of properties on each item are used to determine uniqueness, so when a new item comes in, I compare it against the existing items before inserting it. Since the incoming data is in the form of an RSS feed, there are often many duplicates, and the cost of the uniquing step is O(N^2), which has become significant. Right now, I create a set of existing items before iterating over the list of (possible) new items. My theory is that on the first iteration, all the items will be faulted in, and assuming we aren't pressed for memory, most of those items will remain resident over the course of the iteration. I see my options thusly: Use string comparison for uniquing, iterating over all "new" items and comparing to all existing items (Current approach) Use a predicate to filter the set of existing items against the properties of the "new" items. Use a predicate with Core Data to determine uniqueness of each "new" item (without retrieving the set of existing items). Is option 3 likely to be faster than my current approach? Do you know of a better way?

  • Update existing columns and rows within csv file using Python

    - by wilbev
    So I've been attempting to use the csv module in Python to add data to existing rows and columns, but only specific columns of each row. So for examples let's say my existing csv file has the following: id, name, city, age 1, Ed,, 34 2, Pat,, 23 So basically the city of each person is missing, so I would like to update each row with that person's city. However, the writerow method only seems replace the existing data within the csv file. Changing the open file to append mode just adds the data to a new row. Is there any way to skip the existing data, and only add the city to each row? Thanks

  • Existing web-site CSS replacement (re-skinning) best-practices without changing the HTML

    - by Enigmativity
    I can see a number of other good answers to questions relating to CSS best-practices on stack overflow: How to Manage CSS Explosion CSS Conventions / Code Layout Models Are there any CSS standards that I should follow while writing my first stylesheet? What is the best method for tidying CSS? Best Practices - CSS Stylesheet Formatting But I think I have a different problem. I'm trying to "re-skin" an existing site that has been nicely built using div's and ul's, etc, and it has a good existing CSS file, but when I start making changes to the CSS I quickly find that I break the layout. My feeling is that it is very hard to get a feel for how all the CSS will work together and indeed what CSS is affecting parent and sibling elements in the HTML. So, my question is "what are the best-practices around re-skinning an existing web-site by replacing the CSS only and not modifying the existing HTML?" I can't change the classes, ids, node hierarchy, etc. An example of the particular site that I am trying to re-skin is http://demo.nopcommerce.com/. The existing CSS can be as complicated/detailed as this extract from the main CSS file: .header-selectors-wrapper { text-align: right; float: right; width: 500px; } .header-currencyselector { float: right; } .header-languageselector { float: left; } .header-taxDisplayTypeSelector { float: right; } .header-links-wrapper { float: right; text-align: right; width: 570px; } .header-links { border: solid 1px #9a9a9a; padding: 5px 5px 5px 5px; margin-bottom: 5px; display: inline-table; } .order-summary-content .cart .cart-item-row td, .wishlist-content .cart .cart-item-row td { border-bottom: 1px solid #c5c5c5; vertical-align: middle; line-height: 30px; } .order-summary-content .cart .cart-item-row td.product, .wishlist-content .cart .cart-item-row td.product { text-align: left; padding: 0px 10px 0px 10px; } .order-summary-content .cart .cart-item-row td.product a, .wishlist-content .cart .cart-item-row td.product a { font-weight: bold; } Any help would be appreciated.

  • Create an AWS HVM Linux AMI from an Existing Paravirtual Linux AMI

    - by javacavaj
    Is it possible to create a hardware virtual machine (HVM) AMI from an existing paravirtual (PV) AMI. My initially thought was to start a new PV instance and use the ec2-create-image command to create a new image while specifying HVM as the virutalization type. However, ec2-create-image does not have a command line parameter to specify the virtualization type. Is there another way to go about doing this?
