Selamlar;
Localdeki DNS iniz yavas calistigindan SSH loginlerde reverse dns kaydi
yoklamasi nedeniyle bir yavaslama olabilir. SSH daki yavasligi login
promt unun gec gelmesi olarak anliyorum. Bunun icin /etc/ssh/sshd_config
dosyasi icerisinde "UseDNS no" ekleyip ssh servisini restart eder
misiniz. Bir de sisteminize uzaktan "ssh -vv sorunlusistemipsi" ile
baglanmayi deneyin bakalim, belki ssh baglantisi sirasinda birseyler
yakalayabilirsiniz.
DNS sorunu icin de named i debug modda (named -d ... ) calistirip
nslookup ile local den isim cozmeyi dener misiniz
iyi calismalar
Afsin .
