  • Conditional blocks of code in linux bash

    - by Arek
    Nearly everybody knows very useful && and || operators, for example: rm myf && echo "File is removed successfully" || echo "File is not removed" I've got a question: how to put a block of commands after && or || operators without using the function? For example I want to do: rm myf && \ echo "File is removed successfully" \ echo "another command executed when rm was successful" || \ echo "File is not removed" \ echo "another command executed when rm was NOT successful" What is the proper syntax of that script?

  • Routing Essentials

    - by zharvey
    I'm a programmer trying to fill a big hole in my understanding of networking basics. I've been reading a good book (Networking Bible by Sosinki) but I have been finding that there is a lot of "assumed" information contained, where terms/concepts are thrown at the reader without a proper introduction to them. I understand that a "route" is a path through a network. But I am struggling with visualizing some routing-based concepts. Namely: How do routes actually manifest themselves in the hardware? Are they just a list of IP addresses that get computed at the network layer, and then executed by the transport? What kind of data exists in a so-caleld routing table? Is a routing-table just the mechanism for holding these lists of IP address (read above)? What are the performance pros/cons for having a static route, as opposed to a dynamic route?

  • webmail suite recommendation

    - by hoball
    Hello, I have serveral emails in a few domains (email@domain1, email@domain2, email@domain3). Currently they are on an owned email server and I am collecting emails via IMAP protocol (i would not like to use POP..) in Thunderbird. I have a few partners and I want to allow them to access the same email address. Here is what I desired: All users can open All the inboxes via IMAP @ Thunderbird (with proper configuration) at the same time, there are a webmail system, every user can login their account (userA, userB, userC), and they will see all inboxes (email@domain1, email@domain2, email@domain3) Would you recommend any suite that fits my needs? Either (a system to be installed on my server) or (a remote service where I need to config MX records) will do. Thank you.

  • How to set global PATH on OS X Server 10.6.6?

    - by Adam Lindberg
    I'm running Tomcat on OS X Server 10.6.6 under the normal Web component that comes with the OS. This has worked fine so far, but I need to add some entries to the $PATH environment variable for programs that I want access to from the web server (more specifically, I'm running Hudson under Tomcat which needs access to build tools that I have installed). Tomcat and the Web component seems to run under the user _appserver which has a different $PATH than the administrator account. What's the proper way to add a global entry to the $PATH in OS X Server for the Web component? Preferable it should be done only once so that both the _appserver and Administrator user can access the same $PATH.

  • Should this folder called Data be indexed?

    - by panny
    In the indexing options of Windows 7 there is a folder called Data which is excluded from indexing for the C:\ drive by default. Can someone confirm this, please? I was not able to locate that folder on my drive, nor include it in the search index. The difference in number of indexed files is unsatisfying: windows-7 native indexing service:377703 files on six drives; third party desktop search indexing service:698654 files on the same number of drives. Files in UA Control seem not being indexed without proper priviledges. How can this be circumvented?

  • Limit ftp users to only certain directories in Ubuntu

    - by George
    There are several questions around limiting ftp users to certain directories. However, most of them refer to vsftpd, which I don't think I have installed on my system. I'm running Ubuntu 9.04. How can I tell what ftp service I have installed, and then limit certain users to only the /home/ftpuser directory instead of having full access to the file system? I think I can add them to a separate group and give that group access to the proper directories, but then do I have to remove that groups permissions from all other directories? It seems like there should be an easy way like setting the chroot_local_user value in the /etc/vsftpd/vsftpd.conf file, but that doesn't exist on my system.

  • Connect to MySQL EC2 Instance outside of VPC

    - by Brian W
    I have a VPC setup with a few EC2 instances inside. I'm attempting to connect to a MySQL database on an EC2 instance outside the VPC, with no luck. I have the security groups on the VPC EC2 instances set to outbound 0.0.0.0/0 which I assumed would let it connect to any outbound connection. I also followed a tutorial on creating a NAT, but wasn't exactly sure how to use it to connect to an external database. In any case, if anyone has experience and knows the proper way to connect to a database outside the VPC, it would be greatly appreciated!

  • Where should I go to learn about networking? [closed]

    - by Ollie Saunders
    I wonder if anyone could recommend resource or resources such as a good book that: explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…” I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.

  • How to rsync a large file, with as little CPU and bandwidth expense as possible?

    - by Johan Allgoth
    I have a 500 GB file that I plan on backing up remotely. The file changes often. I'll be rsyncing it from a desktop to a server. Both can run rsync client or server. What is the proper command for this? The ones I've tried sofar has been taking forever or simply acted strange. Example and results: rsync -cv --partial --inplace --no-whole-file /desktop/file1 myserver.com::module/file1 Seems to work, but only if I do it twice (?!). Also, slow. Does the above command do the checksumming on both computers, or only on the sending one? Is it correct otherwise?

  • Copying unicode symbols from Firefox address bar as is

    - by sindikat
    Let's say I open a webpage with some Unicode characters, say, Cyrillic, in the address like this: http://ru.wikipedia.org/wiki/??????????????_?????????????? When I try to copy it from the address bar somewhere else, it becomes unreadable rubbish: http://ru.wikipedia.org/wiki/%D0%A4%D1%83%D0%BD%D0%BA%D1%86%D0%B8%D0%BE%D0%BD%D0%B0%D0%BB%D1%8C%D0%BD%D0%B0%D1%8F_%D0%B7%D0%B0%D0%BA%D1%80%D0%B5%D0%BF%D0%BB%D1%91%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C I guess this is for compatibility. However for readability I want to copy it straight away with proper Unicode characters. What and how should I tweak to make that possible?

  • free Raw-File Converter/Editor

    - by RCIX
    I have RAW files output by a program with a specific set of properties (Photoshop RAW, 16 bits, IBM PC byte order, no header, 1 non-interleaved channel, variable sizes like 257X257 or 129X513); does anyone know of a free tool that will allow me to convert to and from this format, and possibly do basic editing (selection, copy/paste, rotation of selection)? I've tried Picasa, XNView, and Paint Shop Pro 7 and none of them work properly. The closest i get is Paint Shop Pro which will at least make a serviceable attempt to open these files but i can't set all of the proper settings. XNView just might be able to edit it if i can figure out how to change the open settings for a particular raw file. So my questions at current are: how do i tell XNView to open a raw file a particular way? Failing that, is there any free tool that can open Photoshop-RAW files with the above settings (that's not photoshop)? If it helps, i'm trying to import/export/edit hieghtmap data for maps for Supreme Commander.

  • DNS protocol message example

    - by virtual-lab
    hello there, I am trying to figure out how to send out DNS messages from an application socket adapter to a DNSBL. I spent the last two days understanding the basics, including experimenting with WireShark to catch an example of message exchanged. Now I would like to query the DNS without using dig or host command (I'm using Ubuntu); how can I perform this action at low level, without the help of these tools in wrapping the request in a proper DNS message format? How the message should be post it? Hex or String? Thanks in advance for any help. Regards Alessandro Ilardo

  • Mount Docker container contents in host file system

    - by dflemstr
    I want to be able to inspect the contents of a Docker container (read-only). An elegant way of doing this would be to mount the container's contents in a directory. I'm talking about mounting the contents of a container on the host, not about mounting a folder on the host inside a container. I can see that there are two storage drivers in Docker right now: aufs and btrfs. My own Docker install uses btrfs, and browsing to /var/lib/docker/btrfs/subvolumes shows me one directory per Docker container on the system. This is however an implementation detail of Docker and it feels wrong to mount --bind these directories somewhere else. Is there a proper way of doing this, or do I need to patch Docker to support these kinds of mounts?

  • My Tablet PC has a jog dial (typically used for scrolling up and down) but it does not work by defau

    - by techtechmo
    I have an HP Compaq TC4400 and I recently was able to make most of the Tablet PC functions work in Ubuntu 9.10. (The step-by-step guide can be found in my blog.) Unfortunately I have yet to make the jog dial work. This would be particularly useful for scrolling up and down websites and documents when the TC4400 is in slate mode (with no access to the keyboard). I would be much obliged if anybody could tell me: How to find out the input button/key assignment that Ubuntu 9.10 has for jog-up and jog-down; How to assign jog-up to scroll up (D-pad key UP, or PAGE UP) and jog-down to scroll down (D-Pad key DOWN, or PAGE DOWN). I am using xbindkeys to assign different shortcuts to the quick launch buttons, perhaps I could use the same program for the jog dial? I would have done that, except I do not know how to find the proper button/key assignment for xbindkeys to use. Thanks in advance!

  • How to synchronize users, passwords, hosts, etc without NIS

    - by joshxdr
    I am administering a very small solaris 2.6 network with 4 boxes total. Is it possible to use scp or similar to replace NIS for synchronizing users, groups, hosts, etc? This network is only a small part of my job and I don't want to spend too much time on it, and I am worried the setup and maintenence of NIS will not pay off. I need it to behave like a proper multi-user system, when a user logs into any machine, the users, passwords, hosts, etc. are always the same. Is there an easy way to do this with scp? Right now I copy /etc/passwd from one box to another with scp, but sometimes I make mistakes or forget a step, and scp inside of shell scripts don't seem to works so well since they require password authentication. Any recommendations would be welcome.

  • mounting ext4 fs with block size of 65536

  • Graphics Card Compatability

    - by Aaron
    I am a first time builder and while I have the basic understanding of how to put a computer together, one final thing eludes me. What are the requirements for instaling 2 or more graphics cards on a computer? Example: EVGA 015-P3-1589-AR GeForce GTX 580 (Fermi) FTW Hydro Copper 2 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card ECS NGTX580-1536PI-F GeForce GTX 580 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card I am not planning on buying either of these cards in the near future. I simply am using them as an example because of the number of differences. As I understand it these two cards will work together (given the proper motherboard) because the only thing that matters is that they are both GeForce GTX 580. Is my assumption correct? If not, why?

  • RJ45 female to male fault

    - by GeoPhoenix
    i have the following - common - problem, on one end of the cable, there are RJ45 males T586 A which are connected to a 8-port switcher, on the other end, there supposed to be RJ45 females _T586 A which in turn will allow another RJ45 male to be connected. the commonly used color scheme was followed on males (having the head down) blue white blue orange white green green white orange brown white brown the problem i believe is located on female end of cable, which i try multiple time to follow the numbers designated by the module, which is the list above in reverse, and as listed resulting in no signal transmission. tried the T586B (both ends) for device to device once, but no results. Which is the proper way of handling this wiring? There were also additional RJ45 females with the numbers 6-5-4-3, but 1 to 8 isn't supposed to be used for this?

  • How do I create DNS entries for EC2 instances created by Auto Scaling?

    - by Evan
    I'm looking into using auto scaling groups for a tier of webservers that would be fronted by an ELB. One of the things I'm having a hard time with is how to give each new instance the proper DNS name. For example, I'd like webservers to have names like frontend-web-XXX.prod.example.com so their names would appear correct in logs and just ease of organization. I have two other tiers I'd ultimately like to make autoscaled and I'd like them to have names like api-web-XXX.prod.example.com as well. I have some experience with cloudformation templates and have spun up individual instances with associated Route53 records but I don't see any indication of how this can be done within an autoscaled group.

  • Positive result, negative result and current balance. How do you make starting balance show current result?

    - by Tine
    I have 3 columns. Column A shows positive result and if the result is negative then it is in a column B. Column B shows negative result and if the result is positive then it is in a column A. (meaning that either columns can have 0.00 in the cell (empty zero cells)). Column C has starting assets and it also shows the current balance that while result A or B are adding up and current balance is showing the current result. What is the proper formula for this I hope I was clear with my problem. Please help. Thanks in advance!

  • easiest way to (download and) convert HTML-structures into EPUB?

    - by gojira
    How would one (download and) convert HTML-structures into EPUB (or any other format suitable for the Sony PRS-505 reader)? My question is not how to convert a single HTML file into an EPUB file, as this is easy; what I mean is, I have some books I want to read on my Sony PRS-505 and these books are most often online in HTML format but withmany interlinked pages and there is one page with the list of contents, like this example http://www.edge.org/documents/ThirdCulture/d-Contents.html ... or sometimes it's a little bit more complicated as the list of contents only lists the chapters, and inside the chapters there are links to sub-chapters, like in this example: http:SLASHSLASHwww.hyw.com/Books/WargamesHandbook/Contents.htm (I can only post 1 hyperlink now b/c of user restriction, so this is why there is SLASHSLASH instead of //) I want to convert these examples and several others, with correct chapters, images and some acceptable formatting etc, so basically I want to make a proper ebook out of the HTML-tree. What is the easiest way?

  • How do I create certificates for both ends of an stunnel connection?

    - by unixman83
    Hi. I am using stunnel to authenticate RDP (Remote Desktop) and I need to verify that a client possesses the proper credentials. So people cannot brute force into the machine. I am also using a bad (outdated) version of RDP that has security vulnerabilities, so stunnel is a must. I will preshare the necessary .pem's between machines. What are the openssl commands I need to create the right .pem files on both the client and on the server? What files need to be shared?

  • Login authentication vanished from MongoDB install

    - by Robert Oschler
    A few months ago I enabled password protection on my MongoDB install. Today I ran the Mongo client and forgot to use my login details. Instead of rejecting nearly everything I try to do from the shell, like it should, I had complete access to all the databases and collections. Fortunately this instance is only running a few test apps, so I quickly shutdown the MongoD instance until I figure this out. Has anybody ever seen this kind of behavior before and knows what is going on? The MongoD instance is running on a Linux VM hosted by Azure. The only thing I can think of is that perhaps Azure restored an old copy of the VM, but I received no E-mails to that effect and everything else on the server seems to be proper, including new daemon processes that I added after I enabled password protection on MongoD.

  • Remote Desktop Services create LAN and WAN user groups

    - by PHLiGHT
    I'm setting up one server with the gateway, server host and web access roles on it. I know that isn't ideal but I don't expect to have many simulatenous users. I want users to access remote desktop web access and connect to the server host via the gateway as outlined here which avoids opening 3389 to the internet. Users will be connecting from the LAN and the WAN. What I'm looking to do is to allow some users LAN access but not WAN access and added plus would be if security settings (such as no clipboard) would be different when accessing via the WAN. Is this possible? It seems all users can logon to remote desktop web access by default. They can't run the remoteapps once logged in though without the proper permissions. Can I prevent them from even logging into remote web access? Since they renamed it from terminal services to remote desktop services it has made my Googling a bit harder. Thanks!
