Thanks to @Taylor and @Olli I fully revised my question.
Hi,
I'm developing a windows application in ubuntu. Everything is fine. The only problem is that every web call I perform with wininet.dll is sent to localhost instead of target server.
I have no idea what's the problem and how to force wininet.dll to resolve domain name correctly.
I also created the hosts file in ~/.wine/drive_c/windows/system32/drivers/etc/hosts and set domains and IPs manually; but did not help.
Any idea?
Nowadays I'm hearing a lot about the new ~200 line path to Linux kernel that is said makes sensible difference in performance.
Now, do anyone has experience on applying this path on his Ubuntu kernel?
I also saw an alternative way that claimed has a better result:
wget http://launchpadlibrarian.net/59511828/cgroup_patch
chmod +x cgroup_patch
sudo ./cgroup_patch
What do you think this is? Is this validated?
I ask this question because I need more performance but I can't risk on stability.
I'm running Ubuntu 10.04 on my PC with IP 192.168.1.101. every thing work fine, e.g. my web server is running and I can see http://localhost/ or http://192.168.1.101 properly.
But the problem is that I cannot see my PC from my laptop at 192.168.1.102 e.g. at my laptop http://192.168.1.101 gives Connection timed out in browser. or trying to telnet on any port leads to:
telnet: Unable to connect to remote host: Connection timed out
laptop is running a fresh install of Ubuntu as well and there is no setup for firewall stuff in both computers.
PS:
Both computers can ping each other well.
The router is a cicso linksys wireless ADSL modem.
Currently, I can connect to FTP server on the Windows running on 192.168.1.102 from 192.168.1.101 without problem.
I tested the address http://192.168.1.101 with my friends' laptops (They use Windows 7 and XP). both received "Connection was reset". It differs with my laptop's response.

How can i play .ts files in Ubuntu? I would prefer if you could recommend a codec instead of a new piece of software, so I can use any software to play.
And is there any codec pack that make me sure I will be able to play all ordinary media files? Something similar to k-lite codec pack.
note: some of my .ts files already can be played with SMplay, but just some...
PS: as i mentioned above i already can play some .ts files. and i have ubuntu-restricted-extras and mplayer and samplayer in latest version. the problem is that some .ts files that open in windows systems do not play in my ubuntu 10.04
I use krusader for file management stuff. the problem is that apache's DocumentRoot should be under chown www-data:www-data /path/to/www. so using krusader (which is run under my account) I've not write access to /path/to/www while I really need. I don't know how other developers can continue doing things with such a restriction!
I wondered if I could run krusader as www-data then I will be able to easily play with files. but using su - www-data asked me for www-data's password!!
So, how can I run an application (like krusader) as another user (like www-data) in Gnome?
or is there any other solution for my case? (tough I'm really curious to know the answer!)
keep in mind that I know I can run it as root! but this will cause some permission problems when using cp and mkdir, you know.
PS:
sudo and gksudo did not help:
$ gksudo -u -www-data krusader
No protocol specified
krusader: cannot connect to X server :0.0
Final Note:
according the best answer, i did chmod u+w /path/to/www and my problem solved. but i still has not been succeeded in opening krusader as another user!
I have all images of Debian, Ubuntu and Ubuntustudio as .iso. How can I use them as repository to install my desired packages with sudo apt-get install package-name?
I easily mount the .iso file with Archive Mounter, but when adding CD-ROM in Software Sources it says Please Insert CD-ROM.
How should I do this without burning them to disk?
i'm going to create a Catalog for one of our proposals... as i've recently migrated to Ubuntu, i don't know tools to do such a job. In windows i might do this with MS PowerPoint or Adobe InDesign. here i just know OpenOffice Presentation.
I wanna create a simple and official catalog. and i want to have a wast range of available free templates to choose among.
what's the best tool to create a fast, well-looking PDF catalog?
I opened Wine configuration page for the first time while music was playing in the background. Just when I opened the Audio tab, the sound stopped working and Wine alerted me about my audio driver. Now my PC has no sound!
What should I do to get back audio? I don't need audio in Wine.
I have to do three or four jobs a day, and each has several parts. I want a time tracker tool to help me know how much time I've spent on each part and each job overall.
I've found some like gnotime and hamster.
What application do you recommend for such a case?
I'm trying to set Network Proxy to use my LAN's internet connection to update packages.
while the proxy settings works on my firefox, but the package manager still cannot connect to Internet. I have set proxy in System >> Preferences >> Network Proxy and I have entered the user/pass for the proxy in 'Details' too.
How can I make sure that the Proxy Network is applied correctly?
I used Tunnlier in windows and it was perfect. After migrating to Linux I, surprisingly, can't find anything that does the following:
I found PuTTY and gSTM, but they really don't do what I mentioned above.
What do you recommend?
