  • Removing zombie locks in Subversion

    - by ThatBlairGuy
    I'm trying to find a way to remove zombie locks using the Subversion command line tools. The eventual goal is to do this from a hook script, but I haven't been able to work out the command line to use when you only have a physical repository path. (Using svnadmin rmlocks only seems to work for locks which exist in the HEAD revision.) Ideally, I'd like to do this via the post-commit hook script using the command line tools. (I'm aware of the python script for this purpose, but we'd prefer not to install python on that server for this single use.) We're a .NET shop, so creating a tool with the SharpSVN library is also a possibility, but the only unlock capability there appears to be in the SVNClient class. So it's really two questions: Is there a way to do this with the command line tools? If not, is there a way to do it from SharpSVN? (Or perhaps another library?)

  • Configuring my Linux firewall for Tomcat

    - by David Pinn
    I'm following some instructions for Installing Tomcat. They require me to add the following line to my iptables file: -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8080 --syn -j ACCEPT Having carefully read the man page for iptables, I have learned what the parameters do, except for the first one. What does -A RH-Lokkit-0-50-INPUT do, and can you confirm that it is sensible in this case?

  • Groff ignores line breaks from my shell

    - by Fred
    Hello, I've been using groff to make ps files for printing with the -man flag. If I want to convert anything else such as a header file or just the output from ls -l or other program the line breaks are ignored, producing a mess. How can I get groff to see and respect the line breaks in use in the shell?

  • less -Sr colourful.log How to view colourful log in less?

    - by Vi
    Both less -r (preserve terminal control sequences) and less -S (chop long lines) work well alone. But using them together breaks things. It chops too late and it wrecks the next line. Reducing COLUMNS environment variable is no op: (man less) But if you have a windowing system which supports TIOCGWINSZ or WIOCGETD, the window system's idea of the screen size takes precedence over the LINES and COLUMNS environment variables. How to view colourful logs with less? Resoved before asked: less -SR

  • Twitter xAuth vs open source

    - by Yorirou
    Hi I am developing an open source desktop twitter client. I would like to take advantage on the new xAuth authentication method, however my app is open source which means that if I put the keys directly into the source file, it may be a vulnerability (am I correct? The twitter support guy told me). On the other hand, putting the key directly into a binary also doesn't make sense. I am writing my application in python, so if I just supply the pyc files, it is one more seconds to get the keys, thanks to the excellent reflection capatibilities of Python. If I create a small .so file with the keys, it is also trivial to obtain the key by looking at the raw binary (keys has fixed length and character set). What is your opinion? Is it really a secutiry hole to expose the API keys?

  • Why is it I can't use my Windows installation both as a host and a guest?

    - by Josef
    I have Linux installed on my harddrive, sometimes I run it as the host operating system and sometimes run it as a guest in Windows using VirtualBox. It's a nice ability, I think. I don't think it's possible with Windows though. Is it because your average distribution includes drivers for everything known to man? Are devices/drivers configured statically in Windows so when somethings changed it breaks?

  • web2py application logging

    - by MikeWyatt
    What is the recommended way to log application-specific messages in web2py? I found the documentation on HTTP logging, but I'm thinking more of messages for debugging and tracking. Should I simply use the logging module in each separate controller file? Is there a central place in which I could initialize a logger that can be shared between controllers? Or, is something built-in to web2py that I should use? Update: It looks like I can't even fully use the logging module in web2py. It looks like web2py ships with it's own version of the python libraries (in library.zip), which I'm not a big fan of. Is that by design? I'm guessing there will be issues with simply adding my installed Python libraries to the sys.path at run-time, so what should I do?

  • "import as" leads to unresolved import error, "from .. import" does not

    - by Markus R.
    I'm trying to write some plugins for the irc bot supybot with eclipse/pydev. Pydev gives me errors about unresolved imports on supybot-modules/packages (e. g. import supybot.utils as utils), but works ok on e. g. "from supybot.commands import *". So I guess I set up dydev correctly, as it finds the wanted modules. The problem must be in pydev/eclipse, as the bot works correct and in eric5 I get also no errors about that. Removing the interpreter and setting it up didn't help. Any other ideas on how to fix this? System: Arch Linux, Eclipse Juno, PyDev 2.7.1, wanted (and set up) python interpreter is 2.7, supybot is installed in site-packages for Python 2.7. Edit: Just noticed: PyDev doesn't mark the "from ... import *" as error, but if I use functions imported from there I get an error on that function.

  • Setting the secure flag on cookies from Outlook Web Access

    - by Cheekysoft
    I'm running Exchange 2007 SP3 which is exposing outlook web access over only HTTPS. However the server delivers the sessionid cookie without the secure flag set. Even though I don't have port 80 open, this cookie is still vulnerable to being stolen over port 80 in the event of a man-in-the-middle attack. It also contributes to a PCI-DSS failure Does anyone know if I can persuade the web server/application to set the secure flag?

  • Release/Renew IP Address via Terminal in OS X

    - by Rupert
    I am looking to release and renew my IP address in OS X 10.4 using Terminal. Essentially, I need the OS X equivalent of Windows: C:\ ipconfig /release C:\ ipconfig /renew However, I need the interface to remain active during this process, so using ifconfig down/up will not work. I believe I can clear the IP with ifconfig delete but I'm not sure how to get the dhcp client to reassign the address. An article from 2002 suggests using set dhcp but Apple's ifconfig man page does not include this information.

  • How to implement a secure authentication over HTTP?

    - by Zagorax
    I know that we have HTTPS, but I would like to know if there's an algorithm/approach/strategy that grants a reasonable security level without using SSL. I have read many solution on the internet. Most of them are based on adding some time metadata to the hashes, but it needs that both server and client has the time set equal. Moreover, it seems to me that none of this solution could prevent a man in the middle attack.

  • Combining DROP USER and DROP DATABASE with SELECT .. WHERE query?

    - by zsero
    I'd like to make a very simple thing, replicate the functionality of mysql's interactive mysql_secure_installation script. My question is that is there a simple, built-in way in MySQL to combine the output of a SELECT query with the input of a DROP user or DROP database script? For example, if I'd like to drop all users with empty passwords. How could I do that with DROP USER statement? I know an obvious solution would be to run everything for example from a Python script, run a query with mysql -Bse "select..." parse the output with some program construct the drop query run it. Is there an easy way to do it in a simple SQL query? I've seen some example here, but I wouldn't call it simple: http://stackoverflow.com/a/12097567/518169 Would you recommend making a combined query, or just to parse the output using for example Python or bash scripts/sed?

  • What's the max Windows 7 access possible to restrict tampering with single service?

    - by Crawford Comeaux
    I'm developing an ADHD management system for myself. Without going into detail (and as silly as it may sound for a grown man to need something like this), I need to build a me-proof service to run on my Windows 7 Ultra laptop. I still need fairly complete access to the system, though. How can I set things up so that I'm unable to "easily" (ie. within 3-5 mins without rebooting) stop the service or prevent it from running?

  • clear IP address of Ethernet interface

    What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong? EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man

  • How to view history of Yum commands (update, install, remove)?

    - by Chris
    I'm seeing some errors in my apache logs and they may (or may not) be related to some packages that I recently installed/removed using Yum. Is there a way to view the history of Yum packages that have been updated/installed/removed ? I could use the "history" command from unix, but some installations may have been done with different accounts. I've tried searching the web and reading the man page too but haven't found anything.

  • Testifying rasing net.core.somaxconn can make a difference

    - by petermolnar
    I got into an argument on the net.core.somaxconn parameter: I was told that it will not make any difference if we change the default 128. I believed this might be enough proof: "If the backlog argument is greater than the value in /proc/sys/net/core/somaxconn, then it is silently truncated to that value" http://linux.die.net/man/2/listen but it's not. Does anyone know a method to testify this with two machines, sitting on a Gbit network? The best would be against MySQL, LVS, apache2 ( 2.2 ), memcached.

  • How do you handle live video streaming in Flash AS3?

    - by CodeJustin.com
    I've been dabbling with socket servers in Java and now I'm ready to get my feet wet with an idea I had. I would like to use python for my socket server and obviously AS3 for my client. I'm able to create a full chat using my own python socket server but I'm almost clueless what to do now that I want to add in LIVE video (want to make it a live video "chat"). I've found tutorials but they are for FMS and I can not afford that, also Red5 looked nice but couldn't find a live video tutorial off hand (plus I would have to switch to Red5 from my own socket server). So if someone could even nudge me into some resources on the subject (the subject of live video without using FMS) that would be very helpful, Google is failing me right now.
