Derleyemedigim c kodu

di · Ekim 23, 2010

Selamlar,

Kod bazilarinin elinde biraz sakincali bir kod ama yine de koyacagim. Hem 32 bit hem de 64 bit sistemlerde denedim ama basarili olamadim. Daha once 32 bit bir sistem ustunde sorun yasamamistim ama.

Kod :



	char about[] = "juno.c by Sorcerer of DALnetn";

	

	/* 

	 for best results, compile with:

	     gcc -O2 juno.c -o juno

	

	 thanks to bleach for releasing this for me, I'm too lazy to do it myself

	 

	 P.S I'd just like to send out a big "get out of the closet" to malkman,

	  for making useless mods to this source that actually make it *less*

	  effective. Get a life man.

Bu arada derleyemedigim demek biraz yanlis olmus. Bu warning'lerle derleyebiliyorum ve calistirinca su su parametreleri girmedin diyor ama dogru sekilde parametre vesaire girince esas yapmasi gereken gorevi yapmiyor ve "segmentation fault" hatasi veriyor.

senko · Ekim 23, 2010

winde derleyemiyorum su an winsocket fln implement etmek lazim
yalniz 166. satirda nedense sockaddr_in in size'sini alamiyor, almasi lazim aslinda
bi soyle denesene orasi icin

struck sockaddr_in in size'ini almak yerine, o sturta yarattigin degiskenin ismini koy. BSD socket referance'ta oyle yapilmis cunku.

201de bzero fonksiyonuna yamulmuyorsam adres degil pointer gondermemiz gerekiyordu.
gecen sene sapik gibi yazdiydik bsd icin server client fln ama yazmayinca unutluyor iste.

Abi bana yabanci bir dilde konusuyorsun su anda. C'yi zaten zar zor hatirliyorum, ustune benzer tipte bir kodlama hic yapmadim ve kod benim degil.

O yuzden sunu dene bunu dene diyene kadar yapip, yapilmis halini vermen lazim bana =)

ok yarin bi linaksta derlemeye calisayim o zaman :)

juno exploiti değil mi bu ddos için, piyasada ki kodlar ya eksik yada bilerek hatalı bırakılmış halledemediysen atayım ömden çalışanını

di · Ekim 25, 2010

Exploit demek yanlis olur ama evet epeyce hizli bir syn-flooder oluyor bu nane.

Executable halini degil, duzgun derlenebilir kodunu istiyorum esasen. Yanlisi, cozemedigim kismi neymis onu da merak ediyorum.

su patchi uygularsan warningsiz derleniyor, bir tane printf warningi var, inet_ntoa ile ilgili, oda potansiyel crash zaten, belki sef fault sorununuda cozer.
