Merhaba, bir blog olusturma surecine girdim. Aslinda daha onceleri blog olusturdum. (Pek yazi yazmadim) Bu konuda deneyimliyim blog olusturmada! Blog'um uzerinde sistem,programlama ve elektronik konularinda paylasimlar yapmaya karar verdim. Daha once forumlar uzerinde paylasimlarda bulunuyordum zaten. ('nix sistemler, yazilim ve elektronik tamir')
Github, uzerinde paylasimlarda bulunuyorum zaman zaman ama blog acip yazi yazmadim. Bir arama surecine girdim ve benim icin onemli olan kriter basit ve kolaylik pico.sh sitesine goturdu. Github da kolay ama baska yer olsun istedim. Blogumu bu site uzerinde olusturmaya basladim. efek.prose.sh adinda bir blog actim. Ancak pek kolay olmadi kendi isletim sistemimde. Kisisel laptobumda OpenBSD-current ile MacOS-Sonoma kullanmaktayim. MacOS ile blog olusturmak istedigimde baglantida herhangi bir sorun yasamadim. ssh pico.sh dedigimde baglaniyorum.OpenBSD ile denedigimde ise baglantida sorun yasiyorum.Aslinda baglanmaya calisyor surekli ama bir turlu mutlu resmi goremedim ne yazik!
Beklememe ragmen baglanti kurulamiyor! ssh -v pico.sh komutu ile baktigimda burada takildigini gordum.
$ ssh -v pico.sh

Bu sorunun sistemden kaynaklandigi anladim. Adrese ping gonderdigim zaman geri donus olmaktaydi.OpenSSH yazilimina baktigimda, LibreSSL kullandigini gordum. Zaten OpenBSD de bir degisklik yapmadiginiz surece LibreSSL kullaniyor.
$ ssh -V
OpenSSH_9.7, LibreSSL 3.9.0
LibreSSL, OpenBSD'in guvenlik odakli gelistirdigi bir SSL yazilimi..(OpenSSL catali) OpenSSH'i, LibreSSL ile degil de OpenSSL ile entegreli tekrar derlersem bu sorunu asacagimi saniyorum ve ellerimi kirletme zamani gelmistir diyerek, baslatim OpenSSH yazilimi indirmeye! Bu adreste derleme icin gerekli bilgiler bulunmakta ama OpenSSL nerede!!! Soyle bir depolarda arama yaptigimda, OpenSSL yazilimin depolarda oldugunu gordum.
$ pkg_find openssl
1 debug-openssl-1.1.1wp1v0
2 debug-openssl-3.1.6v0
3 debug-openssl-3.2.2v0
4 debug-openssl-3.3.1v0
5 openssl-1.1.1wp1v0
6 openssl-3.1.6v0
7 openssl-3.2.2v0
8 openssl-3.3.1v0
Ben burada 'openssl-3.2.2v0' surumunu kullandim. Neden mi? OpenVPN icin de onu kullandim. Biraz daha stabil bir surumu. OpenSSH yazilimi derleme islemine gecmeden once biraz duzenlemem gerekti. Onun icin 'Makefile.inc' dosyasina soyle bir ekleme yaptim!
OPENSSL?= no
ZLIB?= yes
DSAKEY?= yes
.if (${OPENSSL:L} == "yes")
#CFLAGS+= -DWITH_OPENSSL
OPENSSL_LIBS="-L/usr/local/lib/eopenssl32 -Wl,-rpath,/usr/local/lib/eopenssl32 -lssl -lcrypto" \
OPENSSL_CFLAGS="-I/usr/local/include/eopenssl32/" --with-crypto-library=openssl \
Yazilimi derleme islemi sorunsuz tamamlandigi zaman surum kontrolu yaptigimda!
$ /home/efek/code/ssh/ssh -V
OpenSSH_9.7, without OpenSSL
Sorunsuz bir sekilde LibreSSL yerine artik OpenSSL olarak degistigini gordum! Bana bu kadar yeterli diye kontrol ettigimde. libcryto.so kitapliginin baglanmadigini gordum.
$ ldd /home/efek/code/ssh/ssh/obj/ssh

Sonra ugrasmak yerine deneme yapmaya karar verdim ve sonuc basariliydi.

Basarili bir sekilde sisteme giris yaptim ve herhangi bir sorun gormedim. Tam anlamiyla sisteme entegre edilecekse derleme dosyalari daha detayli incelenmeli ve gerekli yapisal duzenlemeler yapilmali! Ben efek.prose.sh blogumun giris bilgilerimi kaybettigim icin kullanamadim. :) Siz siz olun giris bilgilerinizi yedekleme yapmayi unutmayin. Donmek zorunda kaldim kupcu dukkanina. :)
