  • /etc/inputrc does not seem to be recognized as user on Ubuntu 8.04.2 LTS

    - by Brian Hogg
    On a new installation of Ubuntu 8.04.2 LTS, logging in as a standard user does not maintain the keybindings (whether through sudo su - or direct from ssh). As the root user everything is fine and /root/.inputrc does not exist (only /etc/inputrc) which has its default settings. In addition setting a ~/.bashrc and ~/.profile to the same as the root user (and chown'ing to user:user) has no effect. Am I missing something here?

  • Setting environment variables in OS X /etc/launchd.conf

    - by al nik
    I'm trying to set some env variable in OS X 10.6 (/etc/launchd.conf) setenv M2_HOME /usr/share/maven setenv M2 $M2_HOME/bin setenv MAVEN_OPTS '-Xms256m -Xmx512m' M2 and MAVEN_OPTS are not working. I tried with something like setenv MAVEN_OPTS -Xms256m\ -Xmx512m but still it doesn't work. Any idea of what is the correct synthax? Thanks

  • Multiple routers, subnets, gateways etc

    - by allentown
    My current setup is: Cable modem dishes out 13 static IP's (/28), a GB switch is plugged into the cable modem, and has access to those 13 static IP's, I have about 6 "servers" in use right now. The cable modem is also a firewall, DHCP server, and 3 port 10/100 switch. I am using it as a firewall, but not currently as a DHCP server. I have plugged into the cable modem, two network cables, one which goes to the WAN port of a Linksys Dual Band Wireless 10/100/1000 router/switch. Into the linksys are a few workstations, a few printers, and some laptops connecting to wifi. I set the Linksys to use take static IP, and enabled DHCP for the workstations, printers, etc in 192.168.1.1/24. The network for the Linksys is mostly self contained, backups go to a SAN, on that network, it all happens through that switch, over GB. But I also get internet access from it as well via the cable modem using one static IP. This all works, however, I can not "see" the static IP machines when I am on the Linksys. I can get to them via ssh and other protocols, and if I want to from "outside", I open holes, like 80, 25, 587, 143, 22, etc. The second wire, from the cable modem/fireall/switch just uplinks to the managed GB switch. What are the pros and cons of this? I do not like giving up the static IP to the Linksys. I basically have a mixed network of public servers, and internal workstations. I want the public servers on public IP's because I do not want to mess with port forwarding and mappings. Is it correct also, that if someone breaches the Linksys wifi, they still would have a hard time getting to the static IP range, just by nature of the network topology? Today, just for a test, I toggled on the DHCP in the firewall/cable modem at 10.1.10.1/24 range, the Linksys is n the 192.168.1.100/24 range. At that point, all the static IP machines still had in and out access, but Linksys was unreachable. The cable modem only has 10/100 ports, so I will not plug anything but the network drop into it, which is 50Mb/10Mb. Which makes me think this could be less than ideal, as transfers from the workstation network to the server network will be bottlenecked at 100Mb when I have 1000Mb available. I may not need to solve that, if isolation is better though. I do not move a lot of data, if any, from Linsys network to server network, so for it to pretend to be remote is ok. Should I approach this any different? I could enable DHCP on the cable modem/firewall, it should still send out the statics to the GB switch, but will also be a DHCP in 10.1.10.1/24 range? I can then plug the Linksys into the GB switch, which is now picking up statics and the 10.1.10.1/24 ranges, tell the Linksys to use 10.1.10.5 or so. Now, do I disable DHCP on the Linksys, and the cable modem/firewall will pass through the statics and 10.0.10.1/24 ranges as well? Or, could I open a second DHCP pool on the Linksys? I guess doing so gives me network isolation again, but it is just the reverse of what I have now. But I get out of the bottleneck, not that the Linksys could ever really touch real GB speeds anyway, but the managed switch certainly can. This is all because 13 statics are not that many. Right now, 6 "servers", the Linksys, a managed switch, a few SSL certs, and I am running out. I do not want to waste a static IP on the managed GB switch, or the Linksys, unless it provides me some type of benefit. Final question, under my current setup, if I am on a workstation, sitting at 192.168.1.109, the Linksys, with GB, and I send a file over ssh to the static IP machine, is that literally leaving the internet, and coming back in, or does it stay local? To me it seems like: Workstation (192.168.1.109) -> Linksys DHCP -> Linksys Static IP -> Cable Modem -> Server ( and it hits the 10/100 ports on the cable modem, slowing me down. But does it round trip the network, leave and come back in, limiting me to the 50/10 internet speeds? *These are all made up numbers, I do not use default router IP's as I will one day add a VPN, and do not want collisions. I need some recommendations, do I want one big network, or two isolated ones. Printers these days need an IP, everything does, I can not get autoconf/bonjour to be reliable on most printers. but I am also not sure I want the "server" side of my operation to be polluted by the workstation side of my operation. Unless there is some magic subetting I have not learned yet, here is what I am thinking: Cable modem 10/100, has 13 static IP, publicly accessible -> Enable DHCP on the cable modem -> Cable modem plugs into managed switch -> Managed switch gets 10.1.10.1 ssh, telnet, https admin management address -> Managed switch sends static IP's to to servers -> Plug Linksys into managed switch, giving it 10.1.10.2 static internally in Linksys admin -> Linksys gets assigned 10.1.10.x as its DHCP sending range -> Local printers, workstations, iPhones etc, connect to this -> ( Do I enable DHCP or disable it on the Linksys, just define a non over lapping range, or create an entirely new DHCP at 10.1.50.0/24, I think I am back isolated again with that method too? ) Thank you for any suggestions. This is the first time I have had to deal with less than a /24, and most are larger than that, but it is just a drop to a cabinet. Otherwise, it's a router, a few repeaters, and soho stuff that is simple, with one IP. I know a few may suggest going all DHCP on the servers, and I may one day, just not now, there has been too much moving of gear for me to be interested in that, and I would want something in the Catalyst series to deal with that.

  • /etc/exports file not read on boot

    - by netimen
    I added some entries into my /etc/exports file. But when I boot my system, the file is not read. I check it by sudo exportfs — it returns nothing (also I can't mount the exported folders on other systems). Then I run sudo expotfs -a and then again sudo exportfs — and now all my exported folders are listed (and now I can mount the exported folders on other systems). I'm running kubuntu 9.04 with 2.6.28-11-generic kernel

  • Configuring a monitor's contrast/brightess/colours/etc

    - by DMA57361
    I have recently bought myself a new monitor, now I'd had my previous screen well over 5 years now so I'm looking at this one thinking the picture doesn't quite look right (not bad, just different). Rather than just wait until I'm used to the new picture I'd rather get it fine tuned, then get used to it - so I can reap the maximum benefit. So, can you please suggest reliable ways of configuring an LCD monitor's brightness/contrast/colour/etc to provide the optimum possibly quality image?

  • Dissertation about website and database security - in need of some pointers

    - by ClarkeyBoy
    Hi, I am on my dissertation in my final year at university at the moment. One of the areas I need to research is security - for both websites and for databases. I currently have sections on the following: Website Form security - such as data validation. This section is more about preventing errors made by legitimate users as much as possible rather than stopping hackers, for example comparing a field to a regular expression and giving them meaningful feedback on any errors which did occur so as to stop it happening again. Constraints. For example if a value must be true or false then use a checkbox. If it is likely to be one of several values then use a dropdown or a set of radio boxes, and so on. If the value is unpredictable then use regular expressions to limit what characters they are allowed to enter, and to restrict the length of the string, and sometimes to limit the format (such as for dates / times, post codes and so on). Sometimes you can limit permissions to the form. This is on the occasion that you know exactly who (whether it be peoples names or a group of people - such as administrators or employees) is going to need access to the form. Restricting permissions will stop members of the public from being able to access the form. Symbols or strings which could be used maliciously or cause the website to act incorrectly (such as the script tag) should be filtered out or html encoded. Captcha images can be used to prevent automated systems from filling in and submitting the form. There are some hacks for file uploads - such as using double extensions - which can allow hackers to upload malicious files. Databases (this is nowhere near done yet but the sections I have planned are listed below) SQL statements vs stored procedures Throwing an error when one of the variables contains particular characters or groups of characters (I cant remember what characters they are, but I have seen a message thrown back at me before where I have tried to enter html or something into a text area). SQL Injection - and ways around it, with some examples. Does anyone have any hints and tips on where I could go for some decent, reliable information either about these areas or about other areas of security that I could cover? Thanks in advance. Regards, Richard PS I am a complete newbie when it comes to security, so please be patient with me. If any of the information I have put down is wrong or could be sub-sectioned then please feel free to say so.

  • BitmapFactory.decodeStream returning null when options are set.

    - by Robert Foss
    Hi! I'm having issues with BitmapFactory.decodeStream(). When using it without options, it will return an image. But when I use it with options as in .decodeStream(inputStream, null, options) it never returns Bitmaps. What I'm trying to do is to downsample a Bitmap before I actually load it to save memory. I've read some good guides, but none using .decodeStream. Here httpIM:NOT//nornalbion.SPAMcom/blog/?p=143 httpIM:NOT//kfb-android.blogspot.SPAMcom/2009/04/image-processing-in-android.html WORKS JUST FINE InputStream is = connection.getInputStream(); Bitmap img = BitmapFactory.decodeStream(is, null, options); DOESNT WORK InputStream is = connection.getInputStream(); Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeStream(is, null, options); Boolean scaleByHeight = Math.abs(options.outHeight - TARGET_HEIGHT) >= Math.abs(options.outWidth - TARGET_WIDTH); if(options.outHeight * options.outWidth * 2 >= 200*100*2){ // Load, scaling to smallest power of 2 that'll get it <= desired dimensions double sampleSize = scaleByHeight ? options.outHeight / TARGET_HEIGHT : options.outWidth / TARGET_WIDTH; options.inSampleSize = (int)Math.pow(2d, Math.floor( Math.log(sampleSize)/Math.log(2d))); System.out.println("Samplesize: " + options.inSampleSize); } // Do the actual decoding options.inJustDecodeBounds = false; //options.inTempStorage = new byte[IMG_BUFFER_LEN]; Bitmap img = BitmapFactory.decodeStream(is, null, options);

  • Objective-C classes, pointers to primitive types, etc.

    - by Toby Wilson
    I'll cut a really long story short and give an example of my problem. Given a class that has a pointer to a primitive type as a property: @interface ClassOne : NSObject { int* aNumber } @property int* aNumber; The class is instantiated, and aNumber is allocated and assigned a value, accordingly: ClassOne* bob = [[ClassOne alloc] init]; bob.aNumber = malloc(sizeof(int)); *bob.aNumber = 5; It is then passed, by reference, to assign the aNumber value of a seperate instance of this type of class, accordingly: ClassOne* fred = [[ClassOne alloc] init]; fred.aNumber = bob.aNumber; Fred's aNumber pointer is then freed, reallocated, and assigned a new value, for example 7. Now, the problem I'm having; Since Fred has been assigned the same pointer that Bob had, I would expect that Bob's aNumber will now have a value of 7. It doesn't, because for some reason it's pointer was freed, but not reassigned (it is still pointing to the same address it was first allocated which is now freed). Fred's pointer, however, has the allocated value 7 in a different memory location. Why is it behaving like this? What am I minsunderstanding? How can I make it work like C++ does?

  • Why is document.body == null in Firefox but not Safari

    - by dlamblin
    I have a problem with a page where I am trying to get colorbox (a kind of lightbox for jQuery) working. It doesn't work apparently due to the document.body being null in FireFox (3.5.3). This is not the case in Safari (4.0.3) where the colorbox works. Something that jumps out at me is that (I'm using Drupal 6) drupal has appended a script tag to set some JavaScript variables at the very bottom of the page, below the closing body and html tags. Otherwise I don't see a problem. Unfortunately I'm having a lot of trouble getting it not to do that. Could it be this that's causing FF to have issues with the body? Using colorbox's example files in Firefox does work (and the document.body is defined there). Is there any way I could use jQuery to refill the document.body property with something from $() perhaps, or should I keep banging at drupal to not put a script tag outside the html tags (easier said than done)? To clarify the document.body is null even after the page is done loading. Here's a Firebug console capture: >>> document.body null >>> $().attr('body') null

  • Selenium RC throws sessionsid should not be null exception with assertTextPresent, phpunit 3.4 bug o

    - by user342775
    I am looking to migrate my selenium RC tests to using PHPUnit 3.4.12 from PHPUnit 3.3.2 The selenium test will fail with an exception of the following when I use assertTextPresent() PHPUnit_Framework_Exception: Response from Selenium RC server for getLocation(). ERROR Server Exception: sessionId should not be null; has this session been started yet?. For example: public function testSending($browser) { ... $browser->click("send"); $browser->waitForPageToLoad("30000"); $browser->assertTextPresent("text"); } Below is the selenium RC log (running on Windows): 15:40:19.676 INFO - Command request: isTextPresent[text, ] on session 153d03a123c42098711994f43c2db34 15:40:19.691 INFO - Got result: OK,false on session 153d023a123c42098711994f43cdb34 15:40:19.879 INFO - Command request: testComplete[, ] on session 153d023a123c4298711994f43c2db34 15:40:19.879 INFO - Killing Firefox... 15:40:20.269 INFO - Got result: OK on session 153d023a123c42098711994f43c2db34 15:40:20.472 INFO - Command request: getLocation[, ] on session null 15:40:20.472 ERROR - Exception running 'getLocation 'command on session null java.lang.NullPointerException: sessionId should not be null; has this session been started yet? As you can see, the test should have completed as indicated by the "Killing Firefox" bit, but it instead continued to do something else and triggered the getLocation[, ] command which caused the exception. I have tried the same test with PHPUnit 3.3.2 which did not produce this problem - the test would happily end without the getLocation(). Any ideas? thanks

  • Stack / base pointers in assembly

    - by flyingcrab
    I know this topic has been covered ad-naseum here, and other places on the internet - but hopefully the question is a simple one as I try to get my head around assembly... So if i understand correctly the ebp (base pointer) will point to the top of the stack, and the esp (stack pointer) will point to the bottom -- since the stack grows downward. esp therefore points to the 'current location'. So on a function call, once you've saved the ebp on the stack you insert a new stack frame - for the function. So in the case of the image below, if you started from N-3 you would go to N-2 with a function call. But when you are at N-2 - is your ebp == 25 and the esp == 24 (at least initially, before any data is placed on the stack)? Is this correct or am I of on a tangent here? Thanks!

  • Does JAXWS client make difference between an empty collection and a null collection value as returne

    - by snowflake
    Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !
