  • Yum lock file problem

    - by David Reynolds
    When there are more than 1 copies of yum running, I get this error: Another app is currently holding the yum lock; waiting for it to exit Is there a way to make yum just exit the first time it can't get the lock rather than stay open waiting for it?

  • Acrobat Reader 9 Crashes Every Time

    - by Jess Sightler
    I have an XP machine on which Adobe Acrobat Reader crashes every time as soon as it starts. I've tried reinstalling 9 and it doesn't help at all. If I use it to open a PDF, it displays the first page, and can be scrolled for about 3 seconds before it crashes. Is there some way to debug this?

  • Does mailx send mail using an SMTP relay or does it directly connect to the target SMTP server?

    - by iamrohitbanga
    Suppose i send a mail using the following the following command: mailx [email protected] then does mailx first try to find out the SMTP server of my ISP for relaying the mail or does it connect directly. Does it depend on whether my PC has a public IP address or it is behind a NAT. How do I check the settings of mailx on my PC? How can I verify this using tcpdump?

  • Linux: shortname stuck as "localhost" even though full hostname is correct

    - by DrStalker
    I have a linux (CentOS 5.2) server with the name myserver.mycompnay.com, which is correctly returned when I run 'hostname'. When I run 'hostname -s' however it returns "localhost" which is causing some backup scripts to put stuff in a "localhost" directory instead of a "myserver" directory. All of our other CentOS boxes correctly return the first part of their hostname when 'hostname -s', where do I go on this server to make it behave the same? Other than having "HOSTNAME=myserver.mycompnay.com" in /etc/sysconfig/network what should I be looking at?

  • Ping to IP address returned Destination Unreachable for a different IP address... huh?

    This was totally an isolated incident, but I performed this command: ping 192.168.1.134 and got this result [image]: Pinging 192.168.1.134 with 32 bytes of data: Reply from 192.168.1.133: Destination host unreachable.

I guess I don't understand how this is possible - even given a totally crazy coincidence.

  • How to get predecessor and successors from an adjacency matrix

    - by NickTFried
    Hi I am am trying to complete an assignment, where it is ok to consult the online community. I have to create a graph class that ultimately can do Breadth First Search and Depth First Search. I have been able to implement those algorithms successfully however another requirement is to be able to get the successors and predecessors and detect if two vertices are either predecessors or successors for each other. I'm having trouble thinking of a way to do this. I will post my code below, if anyone has any suggestions it would be greatly appreciated. import java.util.ArrayList; import java.util.Iterator; import java.util.LinkedList; import java.util.Queue; import java.util.Stack; public class Graph<T> { public Vertex<T> root; public ArrayList<Vertex<T>> vertices=new ArrayList<Vertex<T>>(); public int[][] adjMatrix; int size; private ArrayList<Vertex<T>> dfsArrList; private ArrayList<Vertex<T>> bfsArrList; public void setRootVertex(Vertex<T> n) { this.root=n; } public Vertex<T> getRootVertex() { return this.root; } public void addVertex(Vertex<T> n) { vertices.add(n); } public void removeVertex(int loc){ vertices.remove(loc); } public void addEdge(Vertex<T> start,Vertex<T> end) { if(adjMatrix==null) { size=vertices.size(); adjMatrix=new int[size][size]; } int startIndex=vertices.indexOf(start); int endIndex=vertices.indexOf(end); adjMatrix[startIndex][endIndex]=1; adjMatrix[endIndex][startIndex]=1; } public void removeEdge(Vertex<T> v1, Vertex<T> v2){ int startIndex=vertices.indexOf(v1); int endIndex=vertices.indexOf(v2); adjMatrix[startIndex][endIndex]=1; adjMatrix[endIndex][startIndex]=1; } public int countVertices(){ int ver = vertices.size(); return ver; } /* public boolean isPredecessor( Vertex<T> a, Vertex<T> b){ for() return true; }*/ /* public boolean isSuccessor( Vertex<T> a, Vertex<T> b){ for() return true; }*/ public void getSuccessors(Vertex<T> v1){ } public void getPredessors(Vertex<T> v1){ } private Vertex<T> getUnvisitedChildNode(Vertex<T> n) { int index=vertices.indexOf(n); int j=0; while(j<size) { if(adjMatrix[index][j]==1 && vertices.get(j).visited==false) { return vertices.get(j); } j++; } return null; } public Iterator<Vertex<T>> bfs() { Queue<Vertex<T>> q=new LinkedList<Vertex<T>>(); q.add(this.root); printVertex(this.root); root.visited=true; while(!q.isEmpty()) { Vertex<T> n=q.remove(); Vertex<T> child=null; while((child=getUnvisitedChildNode(n))!=null) { child.visited=true; bfsArrList.add(child); q.add(child); } } clearVertices(); return bfsArrList.iterator(); } public Iterator<Vertex<T>> dfs() { Stack<Vertex<T>> s=new Stack<Vertex<T>>(); s.push(this.root); root.visited=true; printVertex(root); while(!s.isEmpty()) { Vertex<T> n=s.peek(); Vertex<T> child=getUnvisitedChildNode(n); if(child!=null) { child.visited=true; dfsArrList.add(child); s.push(child); } else { s.pop(); } } clearVertices(); return dfsArrList.iterator(); } private void clearVertices() { int i=0; while(i<size) { Vertex<T> n=vertices.get(i); n.visited=false; i++; } } private void printVertex(Vertex<T> n) { System.out.print(n.label+" "); } }

  • Show multiple calendars in overlay view by default

    - by Kyle Strand
    In MS Outlook 2007/2010, it's possible to show multiple calendars overlayed on each other (a la Google Calendar; see http://office.microsoft.com/en-us/help/view-calendars-side-by-side-or-overlaid-HA001230157.aspx#BM4). However, it appears that in order to do this, you must first open the calendars side-by-side and then press the little left-arrow button to "combine" them into an overlaid view. Is there a way to make "overlaid" the default view for multiple calendars (again, a la Google Calendar)?

  • How do I make mailto: links open gmail in Ubuntu?

    - by Matthew
    I've tried using this How-To Geek guide, but it doesn't work. Running the script from the terminal works (although I had to change its permissions first), but clicking on a mailto: link does nothing. Note: I am using the Chromium Daily Builds for my browser. I would mailto: links in all applications to point to gmail, not just the ones that I click on in my browser.

  • Telnet disconnected on login failure

    - by LinuxPenseur
    Hi, I have two servers running Linux 2.6.9 kernel. When i telnet to server1 , the telnet will be disconnected only after 3 login failures. While, when i telnet to server2, telnet will be disconnected after the first login failure. I expect server2 to behave the same way as server1 when telnet is executed. Kindly tell me where i should tweak my servers so that i could achieve what i expect. Thanks, LinuxPenseur

  • Hooking up my power switch/reset switch/LEDs

    - by David Oneill
    I'm working on building a computer (first time for me). There are several plugs that I need to connect to the motherboard (Power LED, reset switch, etc). Of the two wires, they are either: Color and white (reset switch, power LED, HDD LED) red and black (speaker, power switch) The manual for the motherboard has a nice diagram of where to plug them in, but has them labeled + or -. Which colors are positive, and which are negative?

  • Is it advisable to use multiple ReadyBoost flash drives?

    - by ymasood
    I am a fan of ReadyBoost and have seen good results using it with my work laptop. I tried something today and connected a second flash drive (2GB) and configured it for use with ReadyBoost. The first is an 8GB configured with 4GB for ReadyBoost. I'm using Windows 7 RC 7100 and was wondering if using more than one ReadyBoost drive helps?

  • XP Suddenly asking for password

    - by ProfKaos
    Is there any sane explanation for a client's Acer Aspire 1 netbook, running XP Home SP 2, suddenly starting to ask for a login password at boot? He has a strict policy of not using passwords, and I removed his login password weeks ago. The story is that suddenly this morning, for the first time, it is asking for a login password.

  • Exchange 2003 Offline Defrag

    - by Tom
    Looking to do my first offline defrag this weekend on Exchange 2003. Our Exchange DB is on E drive and server1 is the temporary location where there is sufficient space. Dismount the store and change to c:\program files\exchsrvr\bin Does this look like the correct command to run? eseutil /d "e:\exchdata\priv1.edb /t"\\server1\exchtemp\tempdfg.edb" Is there anything I should be aware of such as backups running at the same time etc?

  • How can I mount an AES-128 encrypted DMG file using the NTFS file system under Windows XP?

    - by flarn2006
    I found HFSExplorer, which can handle encrypted DMG files, but it only supports HFS, and the DMG I want to open is NTFS. I can't just use any image mounter since the DMG file is encrypted, and I don't want to need to copy it over to my main hard drive first. (The DMG is on an external hard drive.) If copying it is the only way, however, I'd be willing to settle for that, but I'd rather just leave it on the external hard drive in an encrypted form.

  • How can I quickly access the Microsoft Word zoom setting?

    - by nevan
    I get a lot of Word documents to work on, and the first thing I always do is access the zoom setting (View- Zoom) and change the zoom to "Page Width". There's no keyboard shortcut for the zoom settings, and I do it enough times that I'd like a quicker way. In Pages, there's a little pop-up that lets you choose the zoom you want. Is there a way to quickly change the zoom settings in Word? Thanks.

  • Using a pre-existing function for a new row

    - by Jonathan Kushner
    I have an Excel document that contains X columns and N number of rows. The very last column of a row performs a SUM of the first X-1 columns. The problem I have is, the user of this Excel document progressively adds rows to the document, and because of this, the function does not exist yet in the last column for new rows. I need a way to have this function exist in new rows dynamically (the user is not Excel-savvy and doesn't have the ability to just drag the function down a row).

  • Problem with building tree bottom up

    - by Esmond
    Hi, I have problems building a binary tree from the bottom up. THe input of the tree would be internal nodes of the trees with the children of this node being the leaves of the eventual tree. So initially if the tree is empty the root would be the first internal node. Afterwards, The next internal node to be added would be the new root(NR), with the old root(OR) being one of the child of NR. And so on. The problem i have is that whenever i add a NR, the children of the OR seems to be lost when i do a inOrder traversal. This is proven to be the case when i do a getSize() call which returns the same number of nodes before and after addNode(Tree,Node) Any help with resolving this problem is appreciated edited with the inclusion of node class code. both tree and node classes have the addChild methods because i'm not very sure where to put them for it to be appropriated. any comments on this would be appreciated too. The code is as follows: import java.util.*; public class Tree { Node root; int size; public Tree() { root = null; } public Tree(Node root) { this.root = root; } public static void setChild(Node parent, Node child, double weight) throws ItemNotFoundException { if (parent.child1 != null && parent.child2 != null) { throw new ItemNotFoundException("This Node already has 2 children"); } else if (parent.child1 != null) { parent.child2 = child; child.parent = parent; parent.c2Weight = weight; } else { parent.child1 = child; child.parent = parent; parent.c1Weight = weight; } } public static void setChild1(Node parent, Node child) { parent.child1 = child; child.parent = parent; } public static void setChild2(Node parent, Node child) { parent.child2 = child; child.parent = parent; } public static Tree addNode(Tree tree, Node node) throws ItemNotFoundException { Tree tree1; if (tree.root == null) { tree.root = node; } else if (tree.root.getSeq().equals(node.getChild1().getSeq()) || tree.root.getSeq().equals(node.getChild2().getSeq())) { Node oldRoot = tree.root; oldRoot.setParent(node); tree.root = node; } else { //form a disjoint tree and merge the 2 trees tree1 = new Tree(node); tree = mergeTree(tree, tree1); } System.out.print("addNode2 = "); if(tree.root != null ) { Tree.inOrder(tree.root); } System.out.println(); return tree; } public static Tree mergeTree(Tree tree, Tree tree1) { String root = "root"; Node node = new Node(root); tree.root.setParent(node); tree1.root.setParent(node); tree.root = node; return tree; } public static int getSize(Node root) { if (root != null) { return 1 + getSize(root.child1) + getSize(root.child2); } else { return 0; } } public static boolean isEmpty(Tree Tree) { return Tree.root == null; } public static void inOrder(Node root) { if (root != null) { inOrder(root.child1); System.out.print(root.sequence + " "); inOrder(root.child2); } } } public class Node { Node child1; Node child2; Node parent; double c1Weight; double c2Weight; String sequence; boolean isInternal; public Node(String seq) { sequence = seq; child1 = null; c1Weight = 0; child2 = null; c2Weight = 0; parent = null; isInternal = false; } public boolean hasChild() { if (this.child1 == null && this.child2 == null) { this.isInternal = false; return isInternal; } else { this.isInternal = true; return isInternal; } } public String getSeq() throws ItemNotFoundException { if (this.sequence == null) { throw new ItemNotFoundException("No such node"); } else { return this.sequence; } } public void setChild(Node child, double weight) throws ItemNotFoundException { if (this.child1 != null && this.child2 != null) { throw new ItemNotFoundException("This Node already has 2 children"); } else if (this.child1 != null) { this.child2 = child; this.c2Weight = weight; } else { this.child1 = child; this.c1Weight = weight; } } public static void setChild1(Node parent, Node child) { parent.child1 = child; child.parent = parent; } public static void setChild2(Node parent, Node child) { parent.child2 = child; child.parent = parent; } public void setParent(Node parent){ this.parent = parent; } public Node getParent() throws ItemNotFoundException { if (this.parent == null) { throw new ItemNotFoundException("This Node has no parent"); } else { return this.parent; } } public Node getChild1() throws ItemNotFoundException { if (this.child1 == null) { throw new ItemNotFoundException("There is no child1"); } else { return this.child1; } } public Node getChild2() throws ItemNotFoundException { if (this.child2 == null) { throw new ItemNotFoundException("There is no child2"); } else { return this.child2; } } }

  • Do RAID controllers commonly have SATA drive brand compatibility issues?

    - by Jeff Atwood
    We've struggled with the RAID controller in our database server, a Lenovo ThinkServer RD120. It is a rebranded Adaptec that Lenovo / IBM dubs the ServeRAID 8k. We have patched this ServeRAID 8k up to the very latest and greatest: RAID bios version RAID backplane bios version Windows Server 2008 driver This RAID controller has had multiple critical BIOS updates even in the short 4 month time we've owned it, and the change history is just.. well, scary. We've tried both write-back and write-through strategies on the logical RAID drives. We still get intermittent I/O errors under heavy disk activity. They are not common, but serious when they happen, as they cause SQL Server 2008 I/O timeouts and sometimes failure of SQL connection pools. We were at the end of our rope troubleshooting this problem. Short of hardcore stuff like replacing the entire server, or replacing the RAID hardware, we were getting desperate. When I first got the server, I had a problem where drive bay #6 wasn't recognized. Switching out hard drives to a different brand, strangely, fixed this -- and updating the RAID BIOS (for the first of many times) fixed it permanently, so I was able to use the original "incompatible" drive in bay 6. On a hunch, I began to assume that the Western Digital SATA hard drives I chose were somehow incompatible with the ServeRAID 8k controller. Buying 6 new hard drives was one of the cheaper options on the table, so I went for 6 Hitachi (aka IBM, aka Lenovo) hard drives under the theory that an IBM/Lenovo RAID controller is more likely to work with the drives it's typically sold with. Looks like that hunch paid off -- we've been through three of our heaviest load days (mon,tue,wed) without a single I/O error of any kind. Prior to this we regularly had at least one I/O "event" in this time frame. It sure looks like switching brands of hard drive has fixed our intermittent RAID I/O problems! While I understand that IBM/Lenovo probably tests their RAID controller exclusively with their own brand of hard drives, I'm disturbed that a RAID controller would have such subtle I/O problems with particular brands of hard drives. So my question is, is this sort of SATA drive incompatibility common with RAID controllers? Are there some brands of drives that work better than others, or are "validated" against particular RAID controller? I had sort of assumed that all commodity SATA hard drives were alike and would work reasonably well in any given RAID controller (of sufficient quality).

  • Setup SSL for only a Single website on Linux server with Multiple vhosts

    - by user1322092
    Without configuring apache to support SNI, can I purchase a SSL cert and use on a Centos Linux server that has 2 name-based Vhost? I'm only interested in securing ONE of the two domains. Could this be configured in the httpd config file, such as maybe listing the domain that needs to be secured, first etc? I know SNI can be used for multiple certs on a single server with multiple domains. In my case, I'm only interested in securing a single domain.
