헉?
Protocol 2
이건 켜져 있는데 아래 호스트키는 잠겨 있네요~ 이런식으로 사용이 가능하다니...
Protocol 2
도 주석 처리 하는게 좋지 않나요?

서버파일은 공개하기 쉽지 않는데.... 감사합니다. 해보고 댓글 등록 하겠습니다.

안되네요 ssd쪽 문제는 아닌것 같네요... 머가 문제지 ㅡㅡ;;

에러 없이..계속 딜레이 상태면....인증부분 한번 체크해보세요 그 쪽에서 걸린 것 같은데

저도 그부분 예상 했으나 방법을 몰라서^^
어떤 프로그램을 이용해서 sftp접속할때 키값을 뽑아 삽입했는데.... 마찬가지라....

로그는 보셨나요?

로그에안찍혀요..
sftp에 접속하면 로그 찍히게 해놨는데... sftp에 안들어 가지니... 로그에 안뜨네요..
ssh는 당연히 뜨구요 ..
sftp관련 로그가 안뜨지만..

혹시 무슨 방화벽 설정 하셨나요? iptables 이라던가 기타등등..

혹시 접속하는 클라이언트를 알ftp 이용해서 접속하신다면 패시브 모드를 체크해 보셨는지요?

SFTP입니다.
알ftp모드 안되는걸로 알고 있습니다.

PermitRootLogin yes => 이건 no 하시는게. 루트는 다이렉트로 오면 안되구요.

혹시 service sshd restart 하셧나요?

@.@ ?

#리눅스> telnet localhost 22

cmd>telnet 222.222.222.222 22


UsePAM yes <!-- 이거는 자세한거는 모르지만 인증이라서 건들지 않는게 좋습니다.메뉴얼에는 이거 키면 여기서 설정한것 대신에 /etc/pam.d/sshd 파일을 사용한다고 되어 있네요.

PermitRootLogin 요거는 루트작업만 해서 딱히 필요 없을듯합니다. no로 해도 똑같아요^^
리스타트는 변경 작업마다 하고 잇습니다.

문제는 쉘 stfp는 된다는거죠 ㅡㅡ;
인증 문제인듯 합니다...

netstat -alp | grep sftp-server

여기 안떠 있으면 안잡힐거에요.

암것도 안뜨네요...
쉘에서는 되는데..... 그게 상관이 있는건가요?

- 역시 서버는 어려워~

#>sftp -P 이런식으로 되신다는 말씀이신가요?

pstree | grep sftp

netstat -alp | grep sftp

이런식으로 &#45928;을때 서버가 떠야 되는거고,

내 서버에서 sftp -P 22 root@localhost .. 이런식으로 성공하신건가요?

pstree | grep sftp
`-vsftpd


netstat -alp | grep sftp
tcp 0 0 *:ftp *:* LISTEN 3329/vsftpd

다시 찾아 보니 .

#>sftp -oPort=22 root@localhost
#>password : ######
#>ls

되면 내버서에 sftp가 돌아 가는 거고, 안된다면 내서버에 sftp 서버 자체가 안뜬것 같습니다.

The authenticity of host 'localhost (::1)' can't be established.
RSA key fingerprint is 36:c8:fb:5d:19:67:5a:17:9f:3a:ae:7f:be:8a:76:37.
Are you sure you want to continue connecting (yes/no)?yes
비번~

이건 외부에서 오는 인증 자체는 ssh가 된다고 하셧으니 로그인은 됫지만,

ssh가 sftp가 응답하는 것을 막고 있는 건데요.

tunnel 부분이 이상하기는 한데...

ssh 가 된다면 별거 없습니다.
가장 쉽게 알ftp 에서 포트를 맞추시고 프로토콜 자동에 놓으시고 접속하시면 간단하죠.
안될경우 패시브모드를 맞추시면 됩니다.

그리고 UsePAM yes 부분은
pam.d 아래에 sshd 의 내용이 아래처럼 되어있으면 됩니다.
#%PAM-1.0
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
session optional pam_keyinit.so force revoke
session include system-auth
session required pam_loginuid.so

성공하시길...^^

감사합니다.^^
