java - How to view/change socket connection timeout on Linux? -

जावा में एक सॉकेट बनाते समय: 

  नया सॉकेट (होस्ट, पोर्ट);

सॉकेट कन्स्ट्रक्टर आने से पहले host: port से कनेक्ट करने का प्रयास करेगा। विंडोज़ पर, यह अप्राप्य मेजबान के लिए लगभग तुरंत विफल हो जाता है, लेकिन लिनक्स के लिए सॉकेट से टाइमआउट के लिए 5 मिनट लग सकते हैं।

मुझे पता है कि अगर मुझे सॉकेट बनाने पर नियंत्रण है, तो मैं कर सकता हूँ :

<पूर्व> सॉकेट एस = नया सॉकेट (); s.bind (..); S.connect (.., टाइमआउट);

लेकिन मेरे पास ओएस एक उचित डिफ़ॉल्ट मान का उपयोग करना होगा। क्या लिनक्स पर इस सेटिंग को बदलने का कोई तरीका है?

धन्यवाद

मुझे लगता है आप / proc / sys / net / ipv4 / tcp_syn_retries चाहते हैं डिफ़ॉल्ट रूप से आमतौर पर 5 या 6 जो लगभग 3 मिनट तक आती है।

ध्यान दें कि ये सिस्टम-व्यापी हैं।

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space.
