• Is it possible to alias a hostname in linux?

  - by user10178

  I am looking for the right answer to the above question. It has been asked by jmillikin at ubuntu forums as follows: Is it possible to create a hostname alias? Sort of like /etc/hosts, but with other hostnames rather than IP addresses. So that with some file like this, you could ping "fakehost1", and it would be re-mapped to "realhost", and then "realhost" would be resolved to an IP address. # Real host # Aliases realhost fakehost1 fakehost2 fakehost3 Somebody has answered about ssh. But not about ping, etc. My main purpose is to use it as an alias for svn server. In my case, realhost is under dynamic ip. So, "/etc/hosts" alias doesn't work. I want to access my svn server as svn://my_svnserver/my_repos instead of svn://realhost/my_repos. Thanks in advance for any advice.

• Mac Terminal - Color Co-ordinated

  - by Biscuit128

  I would like to create a couple of short cuts on my iMac which ssh on to my dev box and on to my prod box. I would like my dev connection to use the settings something similar to home-brew (green text black background) and my prod connection to use red text black background) - How can this be configured so that this is possible. Would I need multiple bashrc files one for prod and one for dev and source individually? If this is the case, how can i get the profiles to be sources as soon as i double click the shortcuts? Thanks

• Recommended design pattern for object with optional and modifiable attributtes? [on hold]

  - by Ikuzen

  I've been using the Builder pattern to create objects with a large number of attributes, where most of them are optional. But up until now, I've defined them as final, as recommended by Joshua Block and other authors, and haven't needed to change their values. I am wondering what should I do though if I need a class with a substantial number of optional but non-final (mutable) attributes? My Builder pattern code looks like this: public class Example { //All possible parameters (optional or not) private final int param1; private final int param2; //Builder class public static class Builder { private final int param1; //Required parameters private int param2 = 0; //Optional parameters - initialized to default //Builder constructor public Builder (int param1) { this.param1 = param1; } //Setter-like methods for optional parameters public Builder param2(int value) { param2 = value; return this; } //build() method public Example build() { return new Example(this); } } //Private constructor private Example(Builder builder) { param1 = builder.param1; param2 = builder.param2; } } Can I just remove the final keyword from the declaration to be able to access the attributes externally (through normal setters, for example)? Or is there a creational pattern that allows optional but non-final attributes that would be better suited in this case?

• How to move a Windows instance to a different EC2 data centre?

  - by Darren Cook

  I've a Windows EC2 instance running in one region and need to move it to another region (Tokyo and Singapore in this case). Is that even possible? What potential problems do I need to watch out for? (I found http://stackoverflow.com/questions/2181849/ec2-instance-cloning which is describing how to do it, but appears to assume Linux instances, and to assume the same data centre. Is it possible to move my keys across to another region?) I tried something similar with a Windows instance a few months ago, just trying to clone it in the same data centre, but I couldn't get it working quickly, so I had to give up and just create a fresh instance at that time. This time I've got a bit of breathing space, and want to research how to do it properly! Root Device Type: ebs Block Devices: sda1 xvdf (both are ebs, "attached", and have Delete on termination set to "no"; sda1 is the root device) The AMI is described as "Unavailable" (then an ami number).

• How can I rename files and subdirectories in a copied directory based on changes in the original?

  - by GaryF

  I have a directory structure with many hundreds of files and folders underneath it for organising files (in this case photos). I create backups of that directory structure by rsyncing it to identical copies on an external drives periodically. These drives may be offsite some of the time. I want to restructure and rename the files and directories in the original and then, later, when I have an external drive onsite, be able to run some tool that will cause these structural and naming changes to happen on the backup. If I just us rsync, it'll have to recopy much of the data to the backup drive, which I'd rather avoid due to the sizes involved. How can I get the changes I make to the original directory into the backups, as they become available, without having to recopy/rsync the data?

• What are the pros & cons of these MySQL engines for OLTP -- XtraDB, PBXT, or TokuDB?

  - by Continuation

  I'm working on a social website with an approximate read/write split of 90/10. Trying to decide on a MySQL engine. The ones I'm interested in are: XtraDB PBXT TokuDB What are the pros and cons of them for my use case? A few specific questions: PBXT uses log-based structure that avoids double-writes. It sounds very elegant, but the benchmark I've seen doesn't show any/much advantages over XtraDB. Do you have any experience with PBXT/XtraDB you can share? TokuDB sounds VERY interesting. But all the benchmarks I've seen are about single-threaded bulk inserts - inserting 100M rows for example. that's not very relevant for OLTP. What about its performance with large number of concurrent threads writing and reading at the same time? Anyone has tried that?

• In mysql I want to set lower_case_table_names=1 on existing databases to avoid cases-sensitivity issues accross multiple platforms

  - by sakhunzai

  In mysql I want to set lower_case_table_names=1 on existing databases to avoid cases-sensitivity issues accross multiple platforms. A) What are the risks ?( besides show table issue) B) After setting lower_case_table_names=1, will I be in position to query databases across multiple platforms consistantly ? select * from USERS == select * from users; C) How the triggers + stored procedure + functions + views + events will be affected in this regards. I know lower_case_table_names is only for "TABLE" names but how about triggers other database objects . Will they remain case-insensitive How about views ? D) Do I need to rename all tables before/after this configuration setting or this will do the miracle in one step (i.e lower_case_table_names=1 neutralize table names) ? E) What will be the exact steps WRT:mysqd / my.ini ?

• Is it safe to disable clamd?

  - by mk1000

  Clamd is taking up about 5% of my memory (2GB) on my dedicated server and I'm wondering if I can disable it without any security risks. The server just hosts a few of my own websites. For the most part, email received and sent is done through gmail (which connects to my pop3 accounts). The only other email use case is where one of my websites parses all emails and grabs attached images and the subject line. Would there be any security / risks of virus infection if I disable clamd?

• Access boot menu from Windows 8 PC

  - by svnpenn

  I have a computer that came with Windows 8 preinstalled. I want to boot from a CD, in this case Hiren's Boot CD. However Windows 8 doesn't seem to like this. I have tried pressing F8, ESC, F12 and so on. I read online that Windows 8 can boot in 200ms, so that it might not even be possible to boot from a Live CD before Windows loads. I would like to know how to boot from a CD before Windows loads, if possible. If not possible, how to boot from the Live CD after Windows loads.

• Does Virtual Machines with Microsoft server 2003 with Host operating system Vista Home Premium suffer from Vista contraints?

  - by mokokamello

  Experts ! i have a machine with vista home premium and i wanted to share a folder with my colleagues unfortunately i vista allow only 10 concurrent connections to a shared folder one of my colleagues advised me to install a Virtual machine with windows server 2003 so that i will be able to share the folder with more than 1000 user. another colleague stated that the kind of virtual server does not matter, what matters is the host OS, in this case vista. so the folder will be shared by no more than 10 users. my Question is Does Virtual Machines with Microsoft server 2003 with Host operating system Vista Home Premium suffer from Vista contraints?

• Can You Specify Where LVM Snapshots Are (Initially) Stored?

  - by bottles

  Disclaimer: this is my first time using lvm. Upon RTFM, it appears that LVM snapshots are automatically stored in the same directory as the original logical volume. In my case, that would mean the /dev directory. This isn't very nice, because there's not enough disk space in there for me to store a large snapshot. So when I run a command like lvcreate --size 1G --snapshot --name snapshot /dev/lvmData/usr, I need an additional 1G of space free in /dev? Is there any way to specify a different directory in which to store my snapshot?

• Running a script on startup before X starts in Ubuntu 9.10

  - by Epcylon

  I have a script that I want to run at startup to switch X-configs depending on location, but I can't seem to find out where to put it in order to get it to run before X is started. This results in me having to restart X to get it to run the correct config. Currently, my script is located in /etc/init.d/whereami, with symlinks in /etc/rc[2-5].d/S25whereami. I was trying to find out when X is started, in case the problem is simply the 25, but I can't seem to find the answer... Any help is appreciated.

• I think my computer is eating my USB devices

  - by user1068446

  Hi so I think the USB ports on the front of my desktop PC are eating all the devices that are plugged in. (I've found with a couple of USB disks I put at the start of the year, were then unusable on any device after wards). If this is the case, what's likely to be the problem, and how do I fix it? What would a good, simple way to diagnose the problem be? I'm a bit scared to put any of my USB devices in, because that sounds expensive. (I'm thinking I might look out for some cheap old disks).

• Prioritize file sharing capabilities in Windows Server 2008

  - by cmbrnt

  I've got a server running Windows Server 2008, and use it mainly for sharing files throughout the domain from a number of disks. It's running on VMware ESXi 4.0, in case that matters. My problem is that when I log in to the server to check user permissions etc, the access speed the files on the remote disks almost grinds to a halt. I havn't been able to measure the speeds, but I would guess it slows down to about 100kB/s as soon as I log in. This is on a gigabit network and the problems are equal for all users, even the ones connected to the same switch as the server. I've assigned 2 GB RAM to the server, and reserved it 1,5Ghz processor power. I don't have to do anything special on the server for this halt to occur. How can I make sure file sharing is prioritized on the server, so no matter what applications I'm using it will always make sure file sharing works properly? Could this be a VMware issue?

• What makes Ubuntu awesome [closed]

  - by Shagun

  My question may sound stupid or inappropriate for this site in which case I apologize before hand. This thing has bothered me for quiet some time so please correct me if there is anything inappropriate: I have been using Ubuntu for past 1 year and I know how awesome it is and in what terms is it better than windows.But around 2 weeks ago some of my friends asked me to show them something on Ubuntu or tell something about Ubuntu that makes people prefer it over windows. I tried to convince them by telling things like its open-source, that most of the super-computers run on Linux, that its unaffected by virus and other stuff but they seemed unconvinced. Maybe what they we looking for was some mind-boggling feature which only Ubuntu (Linux) has. Since that day I have been thinking but yet don't have anything that will show them the true powers of Linux. Please suggest your response to such a situation as it troubles me that I am not able to explain them one thing that I myself believe in. Thank you. PS : I am not looking for a theoretical answer but would like to hear of one such application which it and only it provides.

• Windows 7 CD Command only echoes directory

  - by Zobbl

  The path for every new instance of the shell starts in my user directory (C:\Users\user). Within this directory or rather drive (in this case C:) I can't use the cd command as I'm used to - it only echoes the specified directory. As soon as I change the directory to a parent-directory I can execute "cd D:" and it changes to the drive. But this behavious doesn't appear consistently in all instances of the shell. Sometimes I have to go to C: to change it. I'm quite sure I'm not using the command in the wrong way, since it's what I'm used to do to start grails.

• I don't have a free PCI / PCI-e slot, can it be worked around?

  - by Borek

  I need to add a PCI(e) card to a nettop PC that is so small that the card won't fit there (and there is no external alternative like we're used to with external TV tuners). The only ports available are USB and eSATA, is it possible to somehow "dock" the PCI card into some device that would then connect to the PC via USB or eSATA? Or am I out of luck? (I don't mind the solution being visually ugly, I wouldn't even mind opening up the case and soldering some wires in, anything that would work would be great.)

• What are the design principles that promote testable code? (designing testable code vs driving design through tests)

  - by bot

  Most of the projects that I work on consider development and unit testing in isolation which makes writing unit tests at a later instance a nightmare. My objective is to keep testing in mind during the high level and low level design phases itself. I want to know if there are any well defined design principles that promote testable code. One such principle that I have come to understand recently is Dependency Inversion through Dependency injection and Inversion of Control. I have read that there is something known as SOLID. I want to understand if following the SOLID principles indirectly results in code that is easily testable? If not, are there any well-defined design principles that promote testable code? I am aware that there is something known as Test Driven Development. Although, I am more interested in designing code with testing in mind during the design phase itself rather than driving design through tests. I hope this makes sense. One more question related to this topic is whether it's alright to re-factor an existing product/project and make changes to code and design for the purpose of being able to write a unit test case for each module?

• Using external monitor and screen resolution?

  - by Johnydep

  it might sound very basic question but i need some help. I have lenovo Ideapad y560p which offers a maximum resolution of 1366px x 768px. Now i am planning to buy an external monitor, and i short listed some FULL HD resolution monitors, but it is my understanding that even with FULL HD, i would only achieve the best resolution my laptop supports. Is it true? And also if this is the case, should i really go for an HD monitor or settle down with a lower resolution version? 2ndly, is there any way to increase resolution with simple upgrade? or it is not possible without voiding the warranty??

• Using windows 7 and fedora

  - by vedant1811

  I need to partition my hard disk for windows and fedora (root, swap, users). I thought of creating 3 (primary drives). 2 small ones (~5GB) each for win7 and fedora and a large (~700GB) for common files (pictures, vidoes, documents, etc.) one. Please Tell me which file systems to use in each case and the set-up of primary and extended partitions. Also I want to know, where and on which file system should the Linux Grub (my choice of OS chooser) be installed. I have just a bought a new Asus K53S and using the Fedora Installer Partitioner (Anaconda). Your help is greatly appreciated.

• SFTP (or similar) server automated setup for group spaces

  - by spikeheap

  I need to build a dedicated machine which will be used to allow our clients to upload and download files in a secure manner. Each client has multiple users, and I would rather not hand out generic client users which are used by multiple people. Each client should have access to their files only, and no others. There is no use-case (yet) for multiple clients interacting with a single file or space. Is there an existing solution to automating the creation and maintenance of these accounts, preferably with a view to integration with LDAP? Currently it looks like if we want to use SFTP with chrooted spaces they will need to be set up manually (or an automation hand-rolled). If a solution exists for a different (but still secure) transfer method, such as FTPS, I'm all ears.

• Access denied for user 'root@localhost' (using password:NO)

  - by murgatroid99

  I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

• Creating fillable PDF form with dynamically updated fields

  - by Aputsiaq

  Is there a way to create fillable PDF forms where a set of fields gets their data when one of the fields is filled out? The normal use case would be application form, where your name or membership number has to be entered on the top of each page. I am using LibreOffice 3.5.4.2. In a earlier version I was able to get the desired effect if I left the field names to be the same (i.e. the field names as seen in the Form Navigator). I'm open for using any free software tool. There is a similiar question asked elsewhere at ask.libreoffice.org.

• Redirect with iptables if destination port is not listened

  - by PoltoS

  I've a server listening on port 10000. But this server is running only in a special case (then some third service is available). Otherwise the port is not listened. Is it possible to redirect the client to another port if 10000 is not listening? I see two solutions: 1) insert/remove iptables rules on server start/stop, but since the server may be killed, it may not insert the correct iptable redirect rule before dieing. 2) make a permanent userspace rule that checks if the port is listening and redirects the packet if not listened. How to do 2) ? Do someone have recipes for ipq? May be someone can suggest me a better way? It is something like fallback redirect: I'll have thousand of clients with different ports (10000-11000) and if their instance of server is not running, whey should be redirected to some page explaining why they don't have and instance connected.
