FC4에서 SELinux 문제로 ftp가 안되는 것 같습니다.

 일단 SELinux는 설치 하지 않았구요. yum을 이용해서 모든 시스템 파일을 업데이트 하고 사용하는데,  proftpd를 사용하려는데 접속이 되지 않았습니다.

 현재

C:Documents and Settings새롬>ftp snu**.com
Connected to snu**.com.
Connection closed by remote host.

C:Documents and Settings새롬>

와 같은 상황이구요,

리눅스 로컬에서는

[root@snujn log]# ftp snu**.com

이상과 같이 아무 문제 없이 작동이 됩니다.

/etc/sysconfig/selinux는

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
#SELINUXTYPE=targeted

이상과 같구요.

/etc/sysconfig/iptables는

입니다.

리눅스 9.0을 사용할 때는 접속이 잘 되었던 셋팅파일들인데, FC4에서 안되는 것으로 보아 SELinux나 보안의 문제로 생각됩니다.

점검해야 할 파일들도 알려주시면 감사하겠습니다.

좋은 답변 기다리겠습니다. ^^;;
