• How do I make everything open in the internal editor in eclipse

  - by Draemon

  I'm using Galileo and plenty of file types work just fine (java, txt) but others open in an external editor. Double clicking on a .sh opens it in emacs. Double clicking on a .py opens bluefish. What sort of madness is this and how do I stop it? I don't want to make an association for each type explicitly; I just want everything to open in the internal editor by default (or preferably Eclim, but that's another issue). Any ideas?

• RewriteRule Works With "Match Everything" Pattern But Not Directory Pattern

  - by kgrote

  I'm trying to redirect newsletter URLs from my local server to an Amazon S3 bucket. So I want to redirect from: https://mysite.com/assets/img/newsletter/Jan12_Newsletter.html to: https://s3.amazonaws.com/mybucket/newsletters/legacy/Jan12_Newsletter.html Here's the first part of my rule: RewriteEngine On RewriteBase / # Is it in the newsletters directory RewriteCond %{REQUEST_URI} ^(/assets/img/newsletter/)(.+) [NC] # Is not a 2008-2011 newsletter RewriteCond %{REQUEST_URI} !(.+)(11|10|09|08)_Newsletter.html$ [NC] ## -> RewriteRule to S3 Here <- ## If I use this RewriteRule to point to the new subdirectory on S3 it will NOT redirect: RewriteRule ^(/assets/img/newsletter/)(.+) https://s3.amazonaws.com/mybucket/newsletters/legacy/$2 [R=301,L] However if I use a blanket expression to capture the entire file path it WILL redirect: RewriteRule ^(.*)$ https://s3.amazonaws.com/mybucket/newsletters/legacy/$1 [R=301,L] Why does it only work with a "match everything" expression but not a more specific expression?

• Apache SSL for login and NON-SSL for everything else (.htacces)

  - by The Devil

  Hey I've almost figured it out on my own but there's something I'm missing. I want to set a couple of directories and files to require SSL and everything else that's not related to those files and dirs to point back to http. So far I have this: RewriteEngine on RewriteBase / # Force ssl for login & admin RewriteCond %{HTTPS} !on RewriteRule ^/?(admin(.*)|login\.php)$ https://%{SERVER_NAME}/$1 [R,NC,L] # Force non-ssl for others RewriteCond %{HTTPS} on RewriteRule ^/?(admin(.*)|login\.php)$ http://%{SERVER_NAME}/$1 [R,NC,L] I'm sure I'm doing something wrong but I just can't figure it out.... The first condition works perfect - whenever I access login.php or /admin/ it points to https. But the second one doesn't... Where have I mistaken ? Thanks in advance!

• tar incremental backup is backing everything up, every time

  - by Cyclic

  I made an incremental backup about 10 months ago (on Jan 27, 2013), creating a .snar metadata file. Now, when I try to make an incremental backup using tar --create --file=dropbox_incremental_1.tar --listed-incremental=dropbox_0.snar Dropbox the command just re-backs up everything. I'm not an expert at Unix timestamps, but I noticed that virtually all of my directory timestamps are way more recent than the last time they changed. For my actual files, they look like this: Access: 2013-03-12 19:04:51.000000000 -0500 Modify: 2012-09-30 15:10:47.000000000 -0500 Change: 2013-03-12 19:04:51.306209672 -0500 The 'Modify' timestamp seems correct, but the files were definitely not changed (at least not doing anything that I know of) at the time they say they were. These files still seem to go into the incremental archive. What's happening here? Is there a way to tell tar to look at the 'modify' timestamp? Isn't this what it's supposed to be doing?

• Can't access internet even though everything is working

  - by entity64

  A friend recently upgraded to a new cable internet connection. The modem connects to the router and various PCs and smartphones from her roommates connect to the router. They don't have any problem accessing the internet. She has Windows 8 and can't access any website (via wifi and ethernet). DNS (UDP) is working, DHCP set up everything correctly, Wifi is working, Trace routes and Pings (ICMP) go through with no problem at all. But neither Dropbox nor Skype nor Spotify nor any browser (all TCP) can access any website. The thing is though, she can connect through the university wifi and via a neighbors wifi. It's just her home connection. No firewalls are running and the computer is clean - no malware. How could it be that only her home connection won't work and others do?

• iptables block everything except http

  - by arminb

  I'm trying to configure my iptables to block any network traffic except HTTP: iptables -P INPUT DROP #set policy of INPUT to DROP iptables -P OUTPUT DROP #set policy of OUTPUT to DROP iptables -A INPUT -p tcp --sport 80 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A OUTPUT -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT The iptables output (iptables -L -v) gives me: Chain INPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 4 745 ACCEPT tcp -- any any anywhere anywhere tcp spt:http state RELATED,ESTABLISHED Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 2 330 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http state NEW,ESTABLISHED When I try to wget 127.0.0.1 (yes i do have a web server and it works fine) i get: --2012-11-14 16:29:01-- http://127.0.0.1/ Connecting to 127.0.0.1:80... The request never finishes. What am I doing wrong? I'm setting iptables to DROP everything by default and add a rule to ACCEPT HTTP.

• Configure redis to not have everything in memory?

  - by acidzombie24

  I like redis because it lets me do operations on data structures. I wanted to see what would happen if i were to put more data into redis then i have for ram. So i wrote a loop that inserted 30k bytes repeatedly and set maxmemory 100MB. I figure it would stay at 100mb. It kept growing. Past 1gb then past 2gb. Suddenly it crashed because i ran the 32bit version. Now... i dont understand what the point of maxmemory is? I am using the windows version so maybe its ignored. Does redis have to have everything in memory? If i have a site (on linux) with a 10gb database and 512mb on the machine will redis work? I don't need it to be amazingly fast i just prefer to modify data in it then sql (although i hope it is still faster then mysql)

• php returns junk characters at end of everything

  - by blindJesse

  php appears to be adding junk characters to the end of everything it returns on a friend's site. I'm not an admin on the server but I'd like to give an informed complaint to get this fixed. The site is http://daytoncodebreakers.org. You can see some junk at the end of every page on the site (what appear to be question marks with something else in the middle). I originally thought this was a wordpress issue, but check out http://daytoncodebreakers.org/whereisini.php (which is just a call to phpinfo), and http://daytoncodebreakers.org/hello.php (which is just 'Hello World'). I'm not sure if this is the most appropriate site, but I think this is a server config issue, so I'm posting it here (rather than stackoverflow or superuser). Feel free to move it if want.

• Chrome logs me out of everything when I exit--tried cookie-related stuff already

  - by GreatBigBore

  I've been using Chrome very successfully for a long time. It has always kept me logged in to all my sites even after exiting the app. Recently it started logging me out of everything when I exit Chrome. I've fooled around with all the various advanced cookie settings, and I've cycled through the options hoping that Chrome just needed a wakeup call or a reset or something. I've also deleted all the cookies in case a corrupted one is confusing Chrome. Nothing works! I see cookies when I log in, but they all go away when I exit Chrome. I've searched all over the place and seen only the standard answers relating to resetting cookies, local data, sessions, that sort of thing. Any Chrome gurus out there, please send a telepathic message to my browser asking it to resume its previous excellent behavior. Alternatively, you could suggest other possible solutions.

• Amazon EC2 instance was not available for few minutes (amazon showed that everything ok)

  - by Salvador Dali

  Few minutes ago my amazon Ec2 instance was unavailable for a few minutes. During this time neither I was able to connect to web-site with http, nor I was able to ssh to it. Also I was not able to connect to my amazon management console for some time (less than amount of unavailability of my instance). When I was able to connect to management console, it was showing me that everything is running smoothly (but I still was not able to connect to instance in any way for a minute or two). During this time I have checked their status page just to see that there is no issues (my instance is in Ireland and there is nothing wrong there today). After that I was able to log in. I checked my logins with last to see that no one except me was logging in. I also looked in apache logs and there was no errors or warnings during this time. Right now when I see my amazon monitor, I see a small spike in CPU in last 15 minutes (but this is from 10% to like 20%) I have no idea what can it be (I have never experienced anything like this before) and therefore I have no idea how scared should I be or what else should I look for. Can anyone give me a hint what my actions should be in such situation?

• How to simply remove everything from a directory on Linux

  - by Tometzky

  How to simply remove everything from a current or specified directory on Linux? Several approaches: rm -fr * rm -fr dirname/* Does not work — it will leave hidden files — the one's that start with a dot, and files starting with a dash in current dir, and will not work with too many files rm -fr -- * rm -fr -- dirname/* Does not work — it will leave hidden files and will not work with too many files rm -fr -- * .* rm -fr -- dirname/* dirname/.* Don't try this — it will also remove a parent directory, because ".." also starts with a "." rm -fr * .??* rm -fr dirname/* dirname/.??* Does not work — it will leave files like ".a", ".b" etc., and will not work with too many files find -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr find dirname -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr As far as I know correct but not simple. find -delete find dirname -delete AFAIK correct for current directory, but used with specified directory will delete that directory also. find -mindepth 1 -delete find dirname -mindeph 1 -delete AFAIK correct, but is it the simplest way?

• Automate open dialog box

  - by Andrey M.

  Is there any way to automate a opening files with open dialog box on Mac OS? The application asks user to open files with the standard open dialog box. But I need open files automatically. The idea is to write script or a small application which will click the button in the target application to open dialog box and then somehow select files which I needed. But I don't know how can I do it. Any suggestions will be very appreciated.

• How to automate BlackBerry debugging with Eclipse?

  - by pajton

  I am developing application for BlackBerry 8900 and I am using features that force me to test/debug it on the real device. I am looking for a convenient way to be able to automate build-deploy-lanuch process. The process is: Package application & sign it Load it on the device Start debugging session in Eclipse With the newest version of BlackBerry plugin for Eclipse, step 1. is almost painless, but I would like to get rid of dialogs that I am missing some debug files. Step 2. and step 3. must be performed manually. Ideally I would like to turn it all into one script, Eclipse macro, whatever.... Has anyone tried something like this with any success?

• Automate Testing on future only items business rules

  - by Titan

  I currently have a business object with a validation business rule, which is it can only be created for the future, tomorrow onwards, and I cannot create new items for today. I have a process, which runs the non-future business objects through some steps.. Because I have to set things up today, and test tomorrow, and when it fails, I can only create a new object tomorrow and test the following day. Are there any easy ways to automate this process in any testing frameworks? I think our testers are using the visual studio 2010 test manager. How do you guys manage situations like this? Cheers

• Automate open dialog in C#? (From COM OCX)

  - by JL

  I have a COM OCX control that I need to automate. It has a method called Open() this method is called without parameters, and always displays an open file dialog (standard one with windows). Is there a way for me to somehow get the file open dialog to open a file I specify , then close the dialog? I would also not like to use sendkeys or any other variants, because I require the solution to be reliable. So ideally would like to grab a handle on that window, and set the file name programatically, and then execute the open method programatically. Thanks in advance.

• Perform manual test, automate after - or never?

  - by dotnetdev

  In my current company, we have one tester. Having spoken to this tester, she says that in testing, before implementing any automation systems, the scripts (steps to take) are manually written and performed (performed at least once). Is this the way things work in testing? To make me laugh, this has been done in this case, yet no automation. It makes me laugh to see the lead tester perform loads of different combinations of usernames and passwords for a login form (which she is not overly keen on having automated) when I could easily automate that (but politics in the company won't allow that). This doesn't seem like the environment where a junior tester (not me, I'm a SDET) cannot learn anything. Thanks

• Automate download of BusinessObjecs Web Intelligence reports

  I'm tasked with automating the retrieval of a couple of BusinessObjects Web Intelligence reports and further processing thereof. I have no other means of access to this data (this was the first avenue I followed), so I will have to do some screen scraping. Alas, the interface seems user-only. Grr! Has anyone done this before? Like to share? Also, does anyone know of a good library for automating the web browser? I know there is a python thingy out there that can be used for testing web applications - I need something in .NET though... What is your favorite? PS: I have also checked this thread (automate getting report from webpage), but am hoping for a Web Intelligence specific sollution.

• Tying down a cloud by virtualizing everything and then locking VMs to real hardware as necessary

  - by tudor

  I'm looking for a cloud software solution that: Can run on both server and desktop machines; Virtualizes hardware and has the option of exposing each real machine to the cloud; Allows a VM to be "locked" to a set of real hardware capabilities and stay there until moved (e.g. a user's "real" desktop); Allows a VM to link to some types of devices elsewhere (e.g. USB/serial via ethernet); and Is geography-aware to control movement of VMs between real networks. I'm aware that this may be the holy grail of virtualization, and I've searched alot. Some solutions appear to meet some criteria but not others. Most cloud implementations appear to ignore real hardware, for example. I realise that this may be solved by using three different implementations in combination: A standard cloud server farm. A bare-metal network backup utility with PXEBoot. VNC and/or VDI. (VNC obviously would require the real hardware to be running.) This combination, however, has some serious drawbacks that I'd like to solve by treating it as one system. My explanation follows... I have a network of real servers and desktops in multiple locations. I've virtualized servers before using Virtualbox and that's worked quite well. I've even connected USB devices to VMs on servers. I would like to virtualize the desktops in all my offices to facilitate movement of desktops, remote access (e.g. VDI) and bare-metal backups. However, I know that there are problems with this. For example, some desktops have specific hardware (e.g. 3D graphics cards, USB devices, etc) that limit their mobility. Geographic constraints also limit movement in that VMs can be moved easily within offices, but transferring between offices is not always preferable. What I would like to find is a system that can virtualize everything from bare-metal easily by maintaining an abstraction layer on each client and server machine that exposes the hardware available and runs as a cloud. Then certain VMs would be "locked" to specific hardware (so that, e.g. the VM runs only on their own desktop.) This would be required for situations where speed is important (e.g. 3D graphics pass-through). In addition, abstracted low-speed devices (e.g. USB) could be piped from real hardware to a VM in the cloud. This is important since if a VM is taken down, another VM can connect to the real hardware for minimum downtime.

• route http and ssh traffic normally, everything else via vpn tunnel

  - by Normadize

  I've read quite a bit and am close, I feel, and I'm pulling my hair out ... please help! I have an OpenVPN cliend whose server sets local routes and also changes the default gw (I know I can prevent that with --route-nopull). I'd like to have all outgoing http and ssh traffic via the local gw, and everything else via the vpn. Local IP is 192.168.1.6/24, gw 192.168.1.1. OpenVPN local IP is 10.102.1.6/32, gw 192.168.1.5 OpenVPN server is at {OPENVPN_SERVER_IP} Here's the route table after openvpn connection: # ip route show table main 0.0.0.0/1 via 10.102.1.5 dev tun0 default via 192.168.1.1 dev eth0 proto static 10.102.1.1 via 10.102.1.5 dev tun0 10.102.1.5 dev tun0 proto kernel scope link src 10.102.1.6 {OPENVPN_SERVER_IP} via 192.168.1.1 dev eth0 128.0.0.0/1 via 10.102.1.5 dev tun0 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 1 This makes all packets go via to the VPN tunnel except those destined for 192.168.1.0/24. Doing wget -qO- http://echoip.org shows the vpn server's address, as expected, the packets have 10.102.1.6 as source address (the vpn local ip), and are routed via tun0 ... as reported by tcpdump -i tun0 (tcpdump -i eth0 sees none of this traffic). What I tried was: create a 2nd routing table holding the 192.168.1.6/24 routing info (copied from the main table above) add an iptables -t mangle -I PREROUTING rule to mark packets destined for port 80 add an ip rule to match on the mangled packet and point it to the 2nd routing table add an ip rule for to 192.168.1.6 and from 192.168.1.6 to point to the 2nd routing table (though this is superfluous) changed the ipv4 filter validation to none in net.ipv4.conf.tun0.rp_filter=0 and net.ipv4.conf.eth0.rp_filter=0 I also tried an iptables mangle output rule, iptables nat prerouting rule. It still fails and I'm not sure what I'm missing: iptables mangle prerouting: packet still goes via vpn iptables mangle output: packet times out Is it not the case that to achieve what I want, then when doing wget http://echoip.org I should change the packet's source address to 192.168.1.6 before routing it off? But if I do that, the response from the http server would be routed back to 192.168.1.6 and wget would not see it as it is still bound to tun0 (the vpn interface)? Can a kind soul please help? What commands would you execute after the openvpn connects to achieve what I want? Looking forward to hair regrowth ...

• Automate the signature of the update.rdf manifest for my firefox extension

  - by streetpc

  Hello, I'm developing a firefox extension and I'd like to provide automatic update to my beta-testers (who are not tech-savvy). Unfortunately, the update server doesn't provide HTTPS. According to the Extension Developer Guide on signing updates, I have to sign my update.rdf and provide an encoded public key in the install.rdf. There is the McCoy tool to do all of this, but it is an interactive GUI tool and I'd like to automate the extension packaging using an Ant script (as this is part of a much bigger process). I can't find a more precise description of what's happening to sign the update.rdf manifest than below, and McCoy source is an awful lot of javascript. The doc says: The add-on author creates a public/private RSA cryptographic key pair. The public part of the key is DER encoded and then base 64 encoded and added to the add-on's install.rdf as an updateKey entry. (...) Roughly speaking the update information is converted to a string, then hashed using a sha512 hashing algorithm and this hash is signed using the private key. The resultant data is DER encoded then base 64 encoded for inclusion in the update.rdf as an signature entry. I don't know well about DER encoding, but it seems like it needs some parameters. So would anyone know either the full algortihm to sign the update.rdf and install.rdf using a predefined keypair, or a scriptable alternative to McCoy whether a command-line tool like asn1coding will suffise a good/simple developer tutorial on DER encoding
