21번 포트가 막혀있을때 포트 변경은 어떻게 하나요

회원 가입하고 많은 글을 보면서 겨우 우분투 대탑 8.10을 깔고 vsftpd로
ftp서버를 돌리는데 성공했습니다.(집 컴퓨터)
그런데 사무실에서 ftp서버를 돌리려고 하니 21번 포트가 막혀있어서 실행이 않됩니다.
아래 방법으로 포트를 바꾸면 된다는데

[size=150:21c4d8xw]예) 21번 포트가 막혀 있는 경우 1024 포트로 변경하기

sudo vi /etc/vsftpd.conf ( 제컴에선 gksu gedit/etc/vsftpd.conf )

*
  listen_port=1024 (1024 포트로 변경)

$sudo /etc/init.d/vsftpd restart 로 재시작 하면 적용 된다.
[/size:21c4d8xw]

listen_port= 가 어디 있는지 모르겠어요.

제컴 포트는 2121입니다.

제 컴 vsftpd.conf 내용입니다.

Example config file /etc/vsftpd.conf

The default compiled in settings are fairly paranoid. This sample file

loosens things up a bit, to make the ftp daemon more usable.

Please see vsftpd.conf.5 for all compiled in defaults.

READ THIS: This example file is NOT an exhaustive list of vsftpd options.

Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd’s

capabilities.

Run standalone? vsftpd can run either from an inetd or as a standalone

daemon started from an initscript.

listen=YES

Run standalone with IPv6?

Like the listen parameter, except vsftpd will listen on an IPv6 socket

instead of an IPv4 one. This parameter and the listen parameter are mutually

exclusive.

#listen_ipv6=YES

Allow anonymous FTP? (Beware - allowed by default if you comment this out).

anonymous_enable=YES

Uncomment this to allow local users to log in.

local_enable=YES

Uncomment this to enable any form of FTP write command.

write_enable=YES

Default umask for local users is 077. You may wish to change this to 022,

if your users expect that (022 is used by most other ftpd’s)

local_umask=022

Uncomment this to allow the anonymous FTP user to upload files. This only

has an effect if the above global write enable is activated. Also, you will

obviously need to create a directory writable by the FTP user.

#anon_upload_enable=YES

Uncomment this if you want the anonymous FTP user to be able to create

new directories.

#anon_mkdir_write_enable=YES

Activate directory messages - messages given to remote users when they

go into a certain directory.

dirmessage_enable=YES

Activate logging of uploads/downloads.

xferlog_enable=YES

Make sure PORT transfer connections originate from port 20 (ftp-data).

connect_from_port_20=YES

If you want, you can arrange for uploaded anonymous files to be owned by

a different user. Note! Using "root" for uploaded files is not

recommended!

#chown_uploads=YES
#chown_username=whoever

You may override where the log file goes if you like. The default is shown

below.

#xferlog_file=/var/log/vsftpd.log

If you want, you can have your log file in standard ftpd xferlog format

#xferlog_std_format=YES

You may change the default value for timing out an idle session.

#idle_session_timeout=600

You may change the default value for timing out a data connection.

#data_connection_timeout=120

It is recommended that you define on your system a unique user which the

ftp server can use as a totally isolated and unprivileged user.

#nopriv_user=ftpsecure

Enable this and the server will recognise asynchronous ABOR requests. Not

recommended for security (the code is non-trivial). Not enabling it,

however, may confuse older FTP clients.

#async_abor_enable=YES

By default the server will pretend to allow ASCII mode but in fact ignore

the request. Turn on the below options to have the server actually do ASCII

mangling on files when in ASCII mode.

Beware that on some FTP servers, ASCII support allows a denial of service

attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd

predicted this attack and has always been safe, reporting the size of the

raw file.

ASCII mangling is a horrible feature of the protocol.

#ascii_upload_enable=YES
#ascii_download_enable=YES

You may fully customise the login banner string:

#ftpd_banner=Welcome to blah FTP service.

You may specify a file of disallowed anonymous e-mail addresses. Apparently

useful for combatting certain DoS attacks.

#deny_email_enable=YES

(default follows)

#banned_email_file=/etc/vsftpd.banned_emails

You may restrict local users to their home directories. See the FAQ for

the possible risks in this before using chroot_local_user or

chroot_list_enable below.

#chroot_local_user=YES

You may specify an explicit list of local users to chroot() to their home

directory. If chroot_local_user is YES, then this list becomes a list of

users to NOT chroot().

#chroot_list_enable=YES

(default follows)

#chroot_list_file=/etc/vsftpd.chroot_list

You may activate the "-R" option to the builtin ls. This is disabled by

default to avoid remote users being able to cause excessive I/O on large

sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

the presence of the "-R" option, so there is a strong case for enabling it.

#ls_recurse_enable=YES

Debian customization

Some of vsftpd’s settings don’t fit the Debian filesystem layout by

default. These settings are more Debian-friendly.

This option should be the name of a directory which is empty. Also, the

directory should not be writable by the ftp user. This directory is used

as a secure chroot() jail at times vsftpd does not require filesystem

access.

secure_chroot_dir=/var/run/vsftpd

This string is the name of the PAM service vsftpd will use.

pam_service_name=vsftpd

This option specifies the location of the RSA certificate to use for SSL

encrypted connections.

rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

This option specifies the location of the RSA key to use for SSL

encrypted connections.

rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

수정할려고 터미널에 gksu gedit/etc/vsftpd.conf 치고 비밀번호 넣으면
하단에 관리프로그램 시작중 뜨다가 없어져 버리네요.

우분투를 처음부터 다시깔고 하면 처음 한번은 됩니다.

혹시 띄어쓰기 잘못하신 건 아닌지?

[code:1xxe7zds]
gksu gedit /etc/vsftpd.conf
[/code:1xxe7zds]

Lbird님 감사합니다.

띄어쓰기 때문에 새로 설치만 오늘도 3번 했습니다.

하지만 아직도 ftp포트는 못잡있습니다.

8080포트는 http://아이피:8080으로 잘 열리네요.
