SeLamLar,
Bir sure once Linux'de maximum socket sayIsInI nasIL arttIrabiLiriz
gibisinden soruLar geLiyordu.. Ekte 2.0.30 sonrasI herhangi bir
kernel iCin patch gonderiyorum.. Bu patch yapILdIGInda linux makinanIz
3000 socket kaLdIrabiLecek duruma geLir.
echo 32768 > /proc/sys/kernel/inode-max
echo 8192 > /proc/sys/kernel/file-max
patch kurduktan sonra sorun cikarsa, komutlarini girmeyi deneyin.
Asagidaki ufak programla da max socket sayisini deneyebilirsiniz..
/* testsocks.c, arslanm@cyberdude.com
*
* Program 7. (echo) porta baglanarak acilabilecek maximum socket sayisini
