• stunnel crashing

  - by Jay

  I'm trying to use stunnel to secure a legacy application's communications. I can't seem to get it setup and working. Can anyone provide any hints where I'm going wrong? Here's what I'm trying to accomplish: A windows service on a client machine connects to a server on port 7000 using TCP. I'd like to encrypt the communication between client and server. Here's what I've tried: Created a new server that accepts ssl connections on port 7443. Got a certificate for the server and installed it. That seems to work with my test setup. Installed stunnel on my windows machine (version 7.43 from the distribution archive file). Installed libssl32.dll and libeay32.dll in the same directory as stunnel.exe ( from the openssl-0.9.8h-1 binary distribution). Installed it as a service using "stunnel -install" Configured stunnel as follows: debug=7 output=C:\p4\internal\Utility\Proxy\proxy.log service=Proxy taskbar=no [exchange] accept=7000 client=yes connect=proxy.blah.com:7443 I changed my hosts file to trick the old application into connecting through stunnel: server.blah.com 127.0.0.1 # when client looks up server it goes to stunnel proxy.blah.com IP-address-of-server.blah.com # stunnel connects to new server "server.blah.com" now resolves to the machine it's running on (i.e. stunnel). "proxy.blah.com" goes to the real server. stunnel should connect to the server. I start the stunnel service and try to connect. It looks like it's working but the stunnel service just shuts down with no message. 2010.04.19 13:16:21 LOG5[4924:3716]: stunnel 4.33 on x86-pc-mingw32-gnu with OpenSSL 0.9.8h 28 May 2008 2010.04.19 13:16:21 LOG5[4924:3716]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2010.04.19 13:16:49 LOG5[4924:3748]: Service exchange accepted connection from 127.0.0.1:4134 2010.04.19 13:16:49 LOG6[4924:3748]: connect_blocking: connecting x.80.60.32:7443 2010.04.19 13:16:49 LOG5[4924:3748]: connect_blocking: connected x.80.60.32:7443 2010.04.19 13:16:49 LOG5[4924:3748]: Service exchange connected remote server from x.253.120.19:4135 2010.04.19 13:20:24 LOG5[3668:3856]: Reading configuration from file stunnel.conf 2010.04.19 13:20:24 LOG7[3668:3856]: Snagged 64 random bytes from C:/.rnd 2010.04.19 13:20:24 LOG7[3668:3856]: Wrote 1024 new random bytes to C:/.rnd 2010.04.19 13:20:24 LOG7[3668:3856]: RAND_status claims sufficient entropy for the PRNG 2010.04.19 13:20:24 LOG7[3668:3856]: PRNG seeded successfully 2010.04.19 13:20:24 LOG7[3668:3856]: SSL context initialized for service exchange 2010.04.19 13:20:24 LOG5[3668:3856]: Configuration successful 2010.04.19 13:20:24 LOG5[3668:3856]: No limit detected for the number of clients 2010.04.19 13:20:24 LOG7[3668:3856]: FD=312 in non-blocking mode 2010.04.19 13:20:24 LOG7[3668:3856]: Option SO_REUSEADDR set on accept socket 2010.04.19 13:20:24 LOG7[3668:3856]: Service exchange bound to 0.0.0.0:7000 2010.04.19 13:20:24 LOG7[3668:3856]: Service exchange opened FD=312 2010.04.19 13:20:24 LOG5[3668:3856]: stunnel 4.33 on x86-pc-mingw32-gnu with OpenSSL 0.9.8h 28 May 2008 2010.04.19 13:20:24 LOG5[3668:3856]: Threading:WIN32 SSL:ENGINE Sockets:SELECT,IPv6 2010.04.19 13:21:02 LOG7[3668:4556]: Service exchange accepted FD=372 from 127.0.0.1:4156 2010.04.19 13:21:02 LOG7[3668:4556]: Creating a new thread 2010.04.19 13:21:02 LOG7[3668:4556]: New thread created 2010.04.19 13:21:02 LOG7[3668:3756]: Service exchange started 2010.04.19 13:21:02 LOG7[3668:3756]: FD=372 in non-blocking mode 2010.04.19 13:21:02 LOG5[3668:3756]: Service exchange accepted connection from 127.0.0.1:4156 2010.04.19 13:21:02 LOG7[3668:3756]: FD=396 in non-blocking mode 2010.04.19 13:21:02 LOG6[3668:3756]: connect_blocking: connecting x.80.60.32:7443 2010.04.19 13:21:02 LOG7[3668:3756]: connect_blocking: s_poll_wait x.80.60.32:7443: waiting 10 seconds 2010.04.19 13:21:02 LOG5[3668:3756]: connect_blocking: connected x.80.60.32:7443 2010.04.19 13:21:02 LOG5[3668:3756]: Service exchange connected remote server from x.253.120.19:4157 2010.04.19 13:21:02 LOG7[3668:3756]: Remote FD=396 initialized 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): before/connect initialization 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write client hello A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server hello A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server certificate A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read server done A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write client key exchange A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write change cipher spec A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 write finished A 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 flush data 2010.04.19 13:21:02 LOG7[3668:3756]: SSL state (connect): SSLv3 read finished A The client thinks the connection is closed: No connection could be made because the target machine actively refused it 127.0.0.1:7000 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Connect(EndPoint remoteEP) at Service.ConnUtility.Connect() Any suggestions?

• How do you re-mount an ext3 fs readwrite after it gets mounted readonly from a disk error?

  - by cagenut

  Its a relatively common problem when something goes wrong in a SAN for ext3 to detect the disk write errors and remount the filesystem read-only. Thats all well and good, only when the SAN is fixed I can't figure out how to re-re-mount the filesystem read-write without rebooting. Behold: [root@localhost ~]# multipath -ll mpath0 (36001f93000a310000299000200000000) dm-2 XIOTECH,ISE1400 [size=1.1T][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=2][active] \_ 1:0:0:1 sdb 8:16 [active][ready] \_ 2:0:0:1 sdc 8:32 [active][ready] [root@localhost ~]# mount /dev/mapper/mpath0 /mnt/foo [root@localhost ~]# touch /mnt/foo/blah All good, now I yank the LUN out from under it.

It says [rw] right there. Not so fast: [root@localhost ~]# touch /mnt/foo/blah touch: cannot touch `/mnt/foo/blah': Read-only file system OK, doesn't do it automatically, I'll just give it a little push: [root@localhost ~]# mount -o remount /mnt/foo mount: block device /dev/mapper/mpath0 is write-protected, mounting read-only The hell you are: [root@localhost ~]# mount -o remount,rw /mnt/foo mount: block device /dev/mapper/mpath0 is write-protected, mounting read-only Noooooooooo. I have tried all sorts of different mount/tune2fs/dmsetup commands and I cannot figure out how to get it to un-flag the block device as write-protected. Rebooting will fix it, but I'd much rather do it on-line. An hour of googling has gotten me nowhere either. Save me ServerFault.

• Can I use ls -R to show up to 2 folder depth?

• wrapBootstrap is no updated and what about copyrights

  - by Greg

  My questions are: Is wrapBootstrap site (for buying themes) no updated? I'm watching the statics of subscribers and of buyers a couple of days and none has been increased. Is it safe to buy a bootstrap theme from there? And what about the copyrights of the buying themes? On my footer I must notice that designer is: "e.g. Company blah blah" or I can only write that I'm the delevoper of the site and nothing about the design?

• How to prevent Google Analytics from adding a second slash between domain and page specific URL when viewing a page?

  - by Jeromy Anglim

  I have a blog http://foo.tumblr.com. I sometimes go to Site Content - All Pages on Google Analytics and then navigate to page listing and then click the icon to take me to that page on my blog. However, instead of opening http://foo.tumblr.com/post/1234/blah.html Google Analytics is opening http://foo.tumblr.com//post/1234/blah.html (i.e., it is adding a second slash between the domain the page specific component of the URL). How can I stop Google Analytics from doing this?

• 2011 The Year of Awesomesauce

  - by MOSSLover

  So I was talking to one of my friends, Cathy Dew, and I’m wondering how to start out this post.  What kind of title should I put?  Somehow we’re just randomly throwing things out and this title pops into my head the one you see above. I woke up today to the buzz of a text message.  I spent New Years laying around until 3 am watching Warehouse 13 Episodes and drinking champagne.  It was one of the best New Year’s I spent with my boyfriend and my cat.  I figured I would sleep in until Noon, but ended up waking up around 11:15 to that text message buzz.  I guess my DE, Rachel Appel, had texted me “Happy New Years”, because Rachel is that kind of person.  I immediately proceeded to check my email.  I noticed my live account had a hit.  The account I rarely ever use had an email.  I sort of had that sinking suspicion I was going to get Silverlight MVP right?  So I open the email and something out of the blue happens it says “blah blah blah SharePoint Server MVP blah blah…”.  I’m sitting here a little confused what?  Really?  Just about when you give up on something the unexplained happens.  I am grateful for what I have every day. So let me tell you a story.  I was a senior in high school and it was December 31st, 1999.  A couple days prior my grandmother was complaining she had a cold and her assisted living facility was not going to let her see a doctor.  She claimed to be very sick.  New Year’s Eve Day 1999 my grandmother was rushed to the hospital sometime very early in the morning.  My uncle, my little brother, and myself were sitting in the waiting room eagerly awaiting news.  The Sydney Opera House was playing in the background as New Years 2000 for Australia was ringing in.  They come out and they tell us my grandmother has pneumonia.  She is in the ICU in critical condition.  Eventually time passes in the day and my parents take my brother and I home.  So in the car we had a huge fight that ended in the worst new years of my life.  The next 30 days were the worst 30 days of my life.  I went to the hospital every single day to do my homework and watch my grandmother.  Each day was a challenge mentally and physically as my grandmother berated me in her demented state.  On the 30th day my grandmother ended up in critical condition in the ICU maxed out on painkillers.  At approximately 3 am I hear my parents telling me they don’t want to wake me up and that my grandmother had passed away.  I must have cried more collectively that day than any other day in my life.  Every New Years Even since I have cried thinking about who she was and what she represented.  She was human looking back she wasn’t anything great, but she was one of the positive lights in my life.  Her and my dad and my other grandmother constantly tried to make me feel great when my mother was telling me the opposite.  I’d like to think since 2000 the past 11 years have been the best 11 years of my life.  I got out of a bad situation by using the tools that I had in front of me.  Good grades and getting into a college so I could aspire to be the person that I wanted to be.  I had some great people along the way to help me out. So getting to the point I like to help people further there lives somehow in the best way I can possibly help out.  This New Years was one of the great years that helped me forget the past and focus on the present.  It makes me realize how far I’ve come since high school and even since college.  The one thing I’ve been grappling with over the years is how do you feel good about making money while helping others out.  I’d to think I try really hard to give back to my community.  I could not have done what I did without other people’s help.  I sent out an email prior to even announcing I got the award today.  I can’t say I did everything on my own.  It’s not possible.  I had the help of others every step of the way.  I’m not sure if this makes sense but the award can’t just be mine.  This award is really owned by each and everyone who helped me get here.  From my dad to my grandmother to Rachel Appel to Bob Hunt to Jason Gallicchio to Cathy Dew to Mark Rackley to Johnny Ennion to Lee Brandt to Jeff Julian to John Alexander to Lori Gowin and to many others.  Thank you guys for all the help and support.

• Sony Vaio Hard Drive replacement won't boot

  - by AJ Bovaird

  I'm working on a Sony Vaio VGN-CR120e. I've cloned the original SATA 1.5 drive with Norton Ghost on to 2 new hard drives, the second of which is a Seagate 7200.4 320Gb 7200 RPM, with the jumper set to limit to SATA 1.5. (The first drive is a WD Scorpio Black 320Gb 7200RMP, which has no SATA 1.5 override support). Neither of the cloned drives will boot - I immediately get a BlackSOD saying: "Windows failed to start blah blah blah" "File \Windows\system32\winload.exe" "Status: 0xc000000e" "Info: The selected entry could not be loaded because the application is missing or corrupt." I've done this hundreds of times on other PC's, and this is the first time I've encountered such an error. Does anyone have any suggestions or advice on how to proceeed, as I would rather not reinstall Vista unless absolutely necessary.

• Sync Windows Live Mail between two computers

  - by Jesper

  Hi, I have a laptop where I have been using Windows Live Mail as my email application for the last year. Yesterday I got a dell desktop as well and I am desperatly trying to set up so my desktop and laptop sync the email between each other. Im using Super Flexible Synchronizer to sync the email storage folder to a NAS on my network, so when setting up the desktop naturally I set it up to download all from the NAS. But each time I open Windows Live Mail on the new machine, some emails suddenly come in duplicates, one is read, the other is not. I have ran through the registry on the new machine and updated an ID i found, in 3 places, one being: C:\Users\\AppData\Local\Microsoft\Windows Live Contacts{blah blah blah}\DBStore\contacts.edb Still doesnt seem to be enough. Does anyone have any tips or ideas how to sync Windows Live Mail between two computers without duplicates and weird behaviour etc. grateful for your help, jesper

• Dual boot Windows 7 with Windows 8- Dynamic Disk

  - by MeetM

  Its a long explanation. I have a HP Pavilion dm4 notebook. It has pre installed Windows 7 Home Pre. Recently, I tried to install Windows 8 developer preview on my notebook, but while installing, it only allowed me to insatll it on my primary Windows 7 drive I.e. drive C. I had kept 1 empty partition for Windows 8 but when I selectced that option, the next button at the bottom of the window just grey with some error saying Windows cannot boot from this drive....blah blah blah So I googled and found another way of doing it by VHD(virtual hard disk). This seemed to work but on restarting gave me "VHD_BOOT_INITIALIZATION_FAILED" error. After trying all possible ways for around 10 times, I gave up. I noticed that d only thing difference in d tutorials and my notebook is the Disk type. They all had Basic and I have Dynamic. Is that the reason m not able to boot Windows 8? Any suggestions?

• Migrating XenServer VMs from Intel to AMD servers

  - by John Smith

  I need to replace my XenServer 6.1 resource pool hardware. I currently run Intel hardware and I have to move to AMD hardware (corporate politics and budget stuff, blah blah blah). I have downtime available so I can use cold migration - live migration is not required. I will also have the new hardware (AMD) alongside the old hardware (Intel). The XenServer docs say there may be problems exporting from one arch and importing to another "may not work" - http://docs.vmd.citrix.com/XenServer/6.1.0/1.0/en_gb/guest.html#importing_vms - but mentions nothing about simply turning off the VM on one arch and then powering it back on new arch. VMs are a mix of OS - some Windows, some Linux, multiple versions. Is this something that can be done with no problems, or are there problems I need to be aware of?

• Windows 7 won't restart with SSD

  - by JL

  I have this annoying problem that I just can't seem to fix. Recently I upgraded my main boot drive to an OCZ Vertex Turbo (60GB) which is an SSD. I've installed Windows 7 64bit. The drive works, and is really quick... blah blah blah. My problem is when I do a restart, for example click start, then arrow next to shutdown, and restart. The computer will shut down, and do a warm reboot, but it gets stuck where it says loading Windows. Just before the animation starts. So what I have to do is physically press the reset switch on the computer, then it restarts, firing up a menu which offers to launch Windows Startup Repair, so I select "Start Windows Normally". After this I boot in normally, but its damn annoying. Any ideas why this is happening, what I can do to fix it?

• Difference between sending data via UDP in Bash and with a Python script

  - by Kevin Burke

  I'm on a Centos box, trying to send a UDP packet to port 8125 on localhost. When I run this Python script: import socket sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.sendto('blah', ("127.0.0.1", 8125)) The data appears where it should on port 8125. However when I send the data like this: echo "blah" | nc -4u -w1 127.0.0.1 8125 Or like this: echo "blah" > /dev/udp/127.0.0.1/8125 The data does not appear in the backend. I know this is horribly vague but it's UDP and it's hard to determine why one packet is being sent and the other is not. Do you have any ideas about how to debug this issue further? I'm on a Centos machine.

• Script to gather all the files ending in .log and create a tar.gz file.

  - by Oscar Reyes

  I'm currently using this script line to find all the log files from a given directory structure and copy them to another directy where I can easily compress them. find . -name "*.log" -exec cp \{\} /tmp/allLogs/ \; The problem I have, is, the directory/subdirectory information gets lost because, I'm copying only the file. For instance I have: ./product/install/install.log ./product/execution/daily.log ./other/conf/blah.log And I end up with: /tmp/allLogs/install.log /tmp/allLogs/daily.log /tmp/allLogs/blah.log And I would like to have: /tmp/allLogs/product/install/install.log /tmp/allLogs/product/execution/daily.log /tmp/allLogs/other/conf/blah.log

However, it doesn't work, for some reason $arg1 is always empty: PS C:\Users\sbi> .\test.ps1 blah .\Dropbox 0: blah 1: .\Dropbox C:\Users\sbi\Dropbox\Photos C:\Users\sbi\Dropbox\Public C:\Users\sbi\Dropbox\sbi PS C:\Users\sbi> Note: The "blah"parameter isn't passed as $arg1. I am absolutely sure this is something hilariously simple (I only just started with doing PS and still feel very clumsy), but I have banged my head against this for more than an hour now, and I can't find anything.

• How do I put a url n a text file and change it to html - making it a shortcut

  - by VISQL

  I've forgotten how to do this. In Windows, you can create a new text document "blah.txt" Inside blah, you can enter a url like http://kongregate.com Then.....??? I forget this step Then you change the file extension of the file to "blah.html" When you double click the file, it acts as a shortcut/hyperlink and takes you to the url you entered in the text file. Can someone tell me what the missing step it? There is something else I need to enter with the url, but I don't know what it is.

• Enter response once prompt returns?

  - by mjb

  It's neither a secure idea nor one I'd recommend elsewhere, but I have a situation when occasionally it takes a while for my Ansible ad-hoc command to respond. I'd love to pipe or args or whatever is needed to push the required text into the prompt so I can walk away and know it will finish. Ex: $ ansible all -m shell -a "reboot" --ask-pass Password: blah blah blah it worked I'd love to send an argument or << or something to get the password in. Is that possible?

• I do not understand -printf script

  - by jerzdevs

  I have taken over the responsibility of RHLE5 scripting and I've not had any training in this platform or BASH scripting. There's a script that has multiple pieces to it and I will ask only about the second piece but also show you the first, I think it will help with my question below. The first part of the script shows the output of users on a particular server: cut -d : -f 1 /etc/passwd The output will look something like: root bin joe rob other... The second script requires me to fill in each of the accounts listed from the above script and run. From what I can gather, and from my search on the man pages and other web searches, it goes out and finds the group owner of a file or directory and obviously sorts and picks out just unique records but not really sure - so that's my question, what does the below script really do? (The funny thing is, is that if I plug in each name from the output above, I'll sometimes receive a "cannot find username blah, blah, blah" message.) find username -printf %G | sort | uniq

• How to dealing with the "programming blowhard"?

  - by Peter G.

  (Repost, I posted this in the wrong section before, sorry) So I'm sure everyone has run into this person at one point or another, someone catches wind of your project or idea and initially shows some interest. You get to talking about some of your methods and usually around this time they interject stating how you should use method X instead, or just use library Y. But not as a friendly suggestion, but bordering on a commandment. Often repeating the same advice over and over like a overzealous parrot. Personally, I like to reinvent the wheel when I'm learning, or even just for fun, even if it turns out worse than what's been done before. But this person apparently cannot fathom recreating ANY utility for such purposes, or possibly try something that doesn't strictly follow traditional OOP practices, and will settle for nothing except their sense of perfection, and thus naturally heave their criticism sludge down my ears full force. To top it off, they eventually start justifying their advice (retardation) by listing all the incredibly complex things they've coded single-handedly (usually along the lines of "trust me, I've made/used program X for a long time, blah blah blah"). Now, I'm far from being a programming master, I'm probably not even that good, and as such I value advice and critique, but I think advice/critique has a time and place. There is also a big difference between being helpful and being narcissistic. In the past I probably would have used a somewhat stronger George Carlin style dismissal, but I don't think burning bridges is the best approach anymore. Maybe I'm just an asshole, but do you have any advice on how to deal with this kind of verbal flogging?

• Types of quotes for an HTML templating language

  - by Ralph

  I'm developing a templating language, and now I'm trying to decide on what I should do with quotes. I'm thinking about having 3 different types of quotes which are all handled differently: backtick ` double quote " single quote ' expand variables ? yes no escape sequences no yes ? escape html no yes yes Backticks Backticks are meant to be used for outputting JavaScript or unescaped HTML. It's often handy to be able to pass variables into JS, but it could also cause issues with things being treated as variables that shouldn't. My variables are PHP-style ($var) so I'm thinking that might mess with jQuery pretty bad... but if I disable variable expansion w/ backticks then, I'm not sure how would insert a variable into a JS code block? Single Quotes Not sure if escape sequences like \n should be treated as literals or converted. I find it pretty rare that I want to disable escape sequences, but if you do, you could use backticks. So I'm leaning towards "yes" for this one, but that would be contrary to how PHP does it. Double Quotes Pretty certain I want everything enabled for this one. Modifiers I'm also thinking about adding modifiers like @ or r in front of the string that would change some of these options to enable a few more combinations. I would need 9 different quotes or 3 quotes and 2 modifiers to get every combination wouldn't I? My language also supports "filters" which can be applied against any "term" (number, variable, string) so you could always write something like "blah blah $var blah"|expandvars Or "my string"|escapehtml Thoughts? What would you prefer? What would be least confusing/most intuitive?

• What is a user-friendly solution to editing email templates with replacement variables?

  - by Daniel Magliola

  I'm working on a system where we rely a lot of "admins / managers" emailing users from the database. One of the key features is being able to email several people at the same time, with specific information relevant to each of them. Another key feature is to be able to hand-craft emails, because it tends to be be necessary to slightly modify them each time, but having a basic template saves a lot of time. For this, we have the typical "templates" solution, where we have a template that looks kind of like this: Hello {{recipient.full_name}}, Your application to {{activity.title}} has been accepted. You have requested to participate on dates {{application.dates}}, in role {{application.role}} Blah blah blah The problem we are having is obviously that (as we expected), managers don't get the whole "variables" idea, and they do things like overwriting them, which doesn't let them email more than one person at a time, assuming those are not going to get replaced and that the system is broken, or even inexplicable things like "Hello {{John}}". The big problem is that this isn't relegated, as usual, to an "admin" section where only a few power users have access to editing the templates that are automatically send out, and they're expected to know what they are doing. Every user of the system gets exposed to this problem. The obvious solution would be to replace the variables before showing this template for the user to edit, but that doesn't work when emailing several people. This seems like a reasonably common problem, and we are kind of hoping that someone has already solved it. Have you seen anywhere/created/can think of good solutions to this problem?

• What if you've been asked to develop a site and the client later introduces Ts&Cs that you'll breach whilst doing your job?

  - by Matt Lacey

  Disclaimer : this is all made up. Honest. And it represents no clients or employers living or dead, blah blah blah, etc. [Allegedly] As part of a website I've built, I've now been provided the Terms and Conditions of site usage to display on the site. These terms--which must be agreed to to access the site--include my (or any visitor to the sites) compliance with a number of clauses. Many of these clauses refer to general computer use and are not tied specifically to use of the site. Some of these clauses refer to things I have had to previously do as a legitimate part of my job and would expect to have to do again. When I've raised similar issues previously my line manager has said just to ignore it but that doesn't seem to be the professional thing to do. So, what do I do? Abiding by the terms would mean that I could no longer work on the project and would cause issues with my employer and the owner of the business the site is being created for. Ignoring them could lead to possible future issues with the business owner and is not something I'm necessarily happy with (the deliberate breaking of a legal contract). Neither option is one I'd choose and could have major consequences. Any thoughts?
