[ilugd] Sync and backup with latest modification time
Hi all, I liked the rsync utility for sync and backup in ubuntu. e.g. rsync -arH source destination would backup files in archive mode(-a), recursively(-r) and preserve hard links(-H). Using this, destination is modified based upon the filesize differences. How do I make rsync to take backup based on latest modified time, doesn't matter if destination file size is larger or smaller than the source file? Any help would be appreciable.

[ilugd] Hijack program run by other pseudo terminal
Hi, Is it possible to hijack process/program which is running on some other pseudo terminal(e.g. pts 0) to the current terminal(say pts 2). I don't want to hijack program of some other user, but I want to interact with the program which I ran some time before like say(20 mins back) and then got disconnected because of network issue, and when I connect back to the server, I get another pts session. Now, all I need to do is interact with the currently running process. I hope, this is not much confusing.

[ilugd] FOSS profit

Right, still I had other intention as well, i.e. to get the perspective of making FOSS as business models on different LUGs.

Release software for free and make money by selling the support to make that software workable? Like say, releasing some so-called buggy or complicated thing for free.

[ilugd] Problem with VMWare workstation on Ubuntu
Hi, I have been facing this problem from quite a long time. I even thought of reporting the bug, but not sure how do I do that. This is because every time I *dare* to see launchpad, I get confused and rush to close the tab as soon as I can. Also, I have bit fear because of the warnings that reads Make sure your bug hasn't already been reported. In fact, I once searched for the related bugs. Well, I'm proud that I was able to go through 2 result pages. :-) Anyway, here is how you can reproduce the bug: -Enable the screen lock if the system is idle for 10 mins -I/O devices are busy working with guest OS inside VMware workstation for more than 10 mins -And when the mouse/keyboard comes out of VM and trying to interact with host OS, the screen is locked Host OS doesn't understand that, while working inside VM the system is *not* idle. Also, similar kind of issue was there when I was using VLC media player on Ubuntu 9.10. As, when watching movie, apparently screen get locked on its standard specified idle timeout. But, I haven't faced this with VLC on Ubuntu 10.04. Has anyone faced the issue?

There are some 32 and 64 bit ubuntu systems in same network. I want only one system(like, one 32 and one 64 bit systems) to be updated and upgraded on daily basis. And, rest of the systems, to fetch those updated packages before they go online and check for new packages. From what I have understood, you don't want every machine to download from the Ubuntu repositories, but only one machine should do the task. It'll handle 32bit and 64bit without any issues. Use one of the following apt-proxy, apt-cacher, apt-cacher-ng, approx I started with apt-cacher and faced update issues in long term use, so I moved to approx and was happy with it, but newer version presented a bit difficulty in the sense that it didn't run its own daemon. So I moved onto apt-cacher-ng which has been working well for quite some time now. I also used apt-cacher in past and it worked but recent versions had some issues, so I kept the old version pinned on my Debian box. I also tried pkg-cacher[1] because I needed to cache for 'yum' (fedora/centos) also and it worked great since it can cache both 'yum' and 'apt'. References: [1] http://gforge.opensource-sw.net/gf/project/pkg_cacher/frs/ HTH Thank you all for your responses. I got options to look into and your views and experience is really valuable. 'apt-cacher-ng' seems to fulfill my requirements. BTW, is it ,by any chance, possible to set up 'repository-cache' server combined for 32 as well as 64 bit systems. apt-cacher-ng uses /var/cache/apt/archives as repository, and is obviously different for 32 and 64 bit systems. The file names of the downloaded packages have architecture mentioned in them, so you don't have to worry about 32-bit packages getting overwritten by 64-bit ones. And I used a single repository with apt-cacher and pkg-cacher. Ok. By that, you mean, once I run 'sudo apt-get update ; sudo apt-get upgrade' on repository-cache server(Ubuntu 10.04 amd64 desktop), provided it has apt-cache-ng installed, will be able to fetch 32 bit debs too? I'm not sure about 'apt-cache-ng', never used it. Or wait How am I supposed to update repository-cache server? I used 'apt-cacher' and 'pkg-cacher' both of which act only when they receive an HTTP request from one of the clients. They're usually installed as a CGI binary, or as a standalone web-server. And when they receive a HTTP request for a file, they perform a cache look-up, and if the file is in cache, they serve it from cache, otherwise they initiate downloading from the source. The first time one of your client updates itself, a 'cache miss' will happen and the packages will be downloaded. And for subsequent updates, the packages are served from the cache. Ok. That was very clear and neat. Thank you. AFAICS, installation with 'apt-cacher-ng' on the systems seems the same way, looking at the configuration page by browsing http://localhost:3124/acng-report.html And yes, Vivek seems right, that apt-cacher-ng uses cache located at /var/cache/apt-cacher-ng/_import. Now, I'm hoping importing already downloaded packages from /var/cache/apt/will be all fine. -- Thanks, Sagar Belure Security Analyst Secfence Technologies www.secfence.com ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd

[ilugd] Distributed updates in Ubuntu
Please, bear with me, if I'm not able to properly present my requirement. There are some 32 and 64 bit ubuntu systems in same network. I want only one system(like, one 32 and one 64 bit systems) to be updated and upgraded on daily basis. And, rest of the systems, to fetch those updated packages before they go online and check for new packages. There is some vague idea in my mind to achieve this. Check the 'master' systems /var/cache/apt/archives directory, list all deb packages and install them accordingly. Make one entry in source.list of each system to do the same. But, I'm not sure how to achieve this. Help is appreciable.

[ilugd] Wget with NULL character

Yes you can use NULL character anywhere, but how're you planning on using NULL character with wget[1] ? 1. As part of URL - you can URL encode the NULL character as '%00'. 2. As part of body - you can pass '\0' over stdin. 3. As command-line argument -- chances are that /proc/$(pidof wget)/cmdline already has some NULL characters. Well, thanks for your reply. Thought, it's not working the way I wanted. After sniffing the network with wireshark, what I could see it in hex values *25 30 30* for '%00'. Seems(to me), while trying to download something with wget, it converts the URL in browser-like format. If so, in that case, it may not be possible to include a NULL character with wget. -- Thanks, Sagar Belure ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd
