I just read the above article. Someone in Communist China has found a way to create a virus in the Android operating system. Android is a Linux fork.
It looks as though the virus is quite specific: it only works on certain apps downloaded from Communist China. I'm hoping that the Google Android version of Linux is different enough from the standard Linux it was "forked" off of that it will be of no concern to we desktop Linux users.
Does this mean that we Linux users must begin running anti-virus software as a continuous process now? What is the chance standard distros will be affected?
Right now to install software from source I do a ./configure && make && make install which doesn't allow for easy uninstallation (some don't come with an 'uninstall' goal, and if they do you have to keep the source around). I'd like to learn how to create binary RPMs from source tar.gz files (one reason being that it makes for easier uninstallation). I tried the following but it complains with the following errors:
Code:
$ rpmbuild -ta mysource.tar.gz
error: Name field must be present in package: (main package)
error: Version field must be present in package: (main package)
error: Release field must be present in package: (main package)
error: Summary field must be present in package: (main package)
error: Group field must be present in package: (main package)
error: License field must be present in package: (main package)
Apparently that's what happens when there is no SPEC file in the tarball. But all the tars I've tried give this same error. Is there a simple way to create binary RPMs from source files - as an example, this source tar [URL].
I have a droid phone, and I have ubuntu 9 running on it. This is done by chrooting since the phone runs a linux kernel. And it works... I have a question though. tightvncserver does work, and its able to listen on 127.0.0.1.. Its how you view your X session. So you chroot to Ubuntu, then start vncserver. Then switch back to android and login to ubuntu via vnc client. but apache, mysql, and postgresql do not work. Well. They dont seem too.. except for mysql. Mysql will start but only if you tell it not to use networking by saying skip-networking in my.cnf
Mysql says: mysqld cant create ip socket permission denied Apache2 says it can find 127.0.0.1 but doesnt actually run same with postgresql... All seem to be compiled with arm architecture. So why does tightvncwork? Why is it so special? How can it listen on the loop back (127.0.0.1) when nothing else can...
I have /proc and /dev bind to the chroot side. I can run ifconfig okay, and I can run /etc/init.d/networking start okay.. But apache2, mysql, etc have problems binding. I have removed apparmor even though technically its not running, but I removed it and its configuration files, just because I thought perhaps mysql looks at apparmor, but I doubted it.
I am working on a project where I need to use the C language to generate a tree of processes. I understand how fork() works but I cant seem to get fork() to create two children from one parent and then have the two children create two more children.
Right now what i am seeing is a chain...where the parent creates one child...and that child creates another ONE child..etc.
Here is what I have so far:

if (childpid = fork()) break;

View 3 Replies View Relatedi was trying to crate a script to show the last time iptables had seen a given IP address (contained in the ipt_recent kernel hook -- my user-defined table name is 'iplist'). The ipt_recent table yields the following information (IPv4 addresses masked for paranoid reasons):
Code:
src=www.xxx.yyy.zzz ttl: 114 last_seen: 9355600126 oldest_pkt: 1 9355600126
src=www.xxx.yyy.zzz ttl: 109 last_seen: 10020040763 oldest_pkt: 1 10020040763
src=www.xxx.yyy.zzz ttl: 111 last_seen: 8106864077 oldest_pkt: 3 8103790647, 8106530788, 8106864077
src=www.xxx.yyy.zzz ttl: 109 last_seen: 9937861664 oldest_pkt: 1 9937861664
src=www.xxx.yyy.zzz ttl: 115 last_seen: 8244867102 oldest_pkt: 1 8244867102
The attempted command used was:
Code:
cat /proc/net/ipt_recent/iplist | awk '{print ($1 ,system("date -d @" $5));}'
Such command yields the following (I'm willing to live with the trailing zero):
Code:

I presume the ipt_recent table uses the standard UNIX epoch timestamp. Am I using the date command syntax incorrectly, is this a 32-bit vs 64-bit break, or it is something else? Please note that I am using FC10, and I have double-checked my system clock settings (both BIOS and OS). The system has only been running during 2009 (no reboot yet).
I want to simplify some of my rules, so I want to create rules for certain services like xmpp, web, etc. since some of them use multiple ports, and I toggle them on/off a lot. Can I simply put the jump to rule clauses in the Input chain, and once the sub chains run, does it return to the input chain after the jump to rule clause? I want to do this so I don't have a ton of rules in the input chain. I think that if I simply make a list of all the rules to jump to in the input chain, it will work itself through all of them until it finds a matching filter in one of them correct?

And it must be a point-and-click GUI.For development I should be able to rely on Open-Source tools on linux only (that means no access to Windows or OSX)The target should be able to install the result relatively easily, that means any dependencies must be freely available, and the setup steps must be very minimal (probably means no installing development tools or running compilers)
My first thought was java, but the standard Swing GUI can look a bit ugly on some platforms. So I'm wondering if there's anything else. My next thought was C++/Qt, but I don't think I can cross-compile this from Debian for Windows or OSX, can I? Next I thought of python and PyQt, but it looks like PyQt isn't available for OSX. And finally I even thought of making some kind of web application running on a tiny web server of some kind, then accessing it with a native browser, but I'm pretty sure this doesn't meet the "easy to install" criteria. I'm finding this so tricky, do all the existing cross-platform applications use natively-compiled C++ for this? Or is there an obvious alternative that I'm overlooking?

Our application is based on the C++ devlopment which requires so many of packages dependent on the Ubuntu OS, Graphics libraries, Development packages and other dependent libraries. So we need to configure all those every time in a new PC when we add. Is there any other way to do this job very easily and the any method to create our application executable to run in all PCs with the dependencies packages installed.
