Как настроить pure-ftpd на анонимное удаление файлов

Сообщение macrus »

Всем привет. Я перелапатил весь файл с настройками Pure-ftpd, который я поставил, и не могу доселе разобратся с некотрыми настройками. Мне нужно сделать, чтобы на сервере можно было переименовывать и удалять файлы/папки, и столкнулся вот с таким непонятным мне, так как я новичек, ностроечкой в конфиге

# File creation mask. <umask for files>:<umask for dirs> .
# 177:077 if you feel paranoid.

Umask                       133:022

Здесь я так понял это права для создающихся файлов:папок. Но здесь ведь по три цыфры, а не четыре.
Вот я на вякий случай показываю свой pure-ftpd.conf

Код:

And there are 20 anonymous sessions max. # PerUserLimits 3:20 # When a file is uploaded and there is already a previous version of the file # with the same name, the old file will neither get removed nor truncated. # Upload will take place in a temporary file and once the upload is complete, # the switch to the new version will be atomic. For instance, when a large PHP # script is being uploaded, the web server will still serve the old version and # immediatly switch to the new one as soon as the full file will have been # transfered. This option is incompatible with virtual quotas. # NoTruncate yes # This option can accept three values : # 0 : disable SSL/TLS encryption layer (default). # 1 : accept both traditional and encrypted sessions. # 2 : refuse connections that don't use SSL/TLS security mechanisms, # including anonymous sessions. # Do _not_ uncomment this blindly. Be sure that : # 1) Your server has been compiled with SSL/TLS support (--with-tls), # 2) A valid certificate is in place, # 3) Only compatible clients will log in. # TLS 1 # Listen only to IPv4 addresses in standalone mode (ie. disable IPv6) # By default, both IPv4 and IPv6 are enabled. # IPV4Only yes # Listen only to IPv6 addresses in standalone mode (ie. disable IPv4) # By default, both IPv4 and IPv6 are enabled. # IPV6Only yes # UTF-8 support for file names (RFC 2640) # Define charset of the server filesystem and optionnally the default charset # for remote clients if they don't use UTF-8. # Works only if pure-ftpd has been compiled with --with-rfc2640 # FileSystemCharset big5 # ClientCharset big5


Помогите плиз мне разобраццо с этим :)

)) А я вот не могу разобраться, прошу помощи. Аналогичная проблема.

Ситуация: debian, поставил pure-ftpd из репозитария, он сам прописался в init.d в автозагрузку, через скрипт wrapper'а. Т.е. конфиги он видит как файлы папке /etc/pure-ftpd/conf, читает их содержимое и парсит.

Соответственно содержание папки /etc/pure-ftpd/conf (вместе с текстом внутри файлов) таково:

Код: Выделить всё

AllowAnonymousFXP (no)
AllowUserFXP (no)
AltLog (clf:/var/log/pure-ftpd/transfer.log)
AnonymousCanCreateDirs (yes)
AnonymousOnly (yes)
ChrootEveryone (yes)
DisplayDotFiles (no)
DontResolve (yes)
IPV4Only (yes)
MaxClientsPerIP (10)
MaxDiskUsage (80)
MinUID (1000)
NoChmod (yes)
NoRename (no)
PAMAuthentication (no)
ProhibitDotFilesWrite (yes)
PureDB (/etc/pure-ftpd/pureftpd.pdb)
Umask (111 000)
UnixAuthentication (no)
UserBandwidth (5120)


Далее в системе есть пользователь ftp (1001) из группы ftpgroup (1001) и есть директория /home/ftp с владельцем ftp:ftpgroup и правами 555 (чтобы аноним не мог ничего менять\создавать в корне ftp), и еще есть директория /home/ftp/incoming с тем же владельцем и правами 777.

При входе на фтп ничего удалять\изменять из корня нельзя, как и предполагалось, а если зайти в incoming, то туда можно закачивать файлы, скачивать от туда, создавать там папки и в них что-то закачивать, но удалять\переименовывать ничего нельзя, т.е. нелья удалить то что закачал или удалить папку которую создал, где что не так я делаю? При создании папок они автоматом внутри инкаминг получают права 777, а файлы получают права 666 (по Umask).

добавил еще три параметра (так как не знаю какие дефолтные), которые могли бы отвечать за возможность удаления файлов:
AntiWarez (no)
AutoRename (no)
KeepAllFiles (no)

пока тот же результат... help...

убрал вход только для анонимов, зашел под собой, лазил по своим папкам, мог создавать папки и удалять, закачивать в них чтонить и тоже удалять, вообщем все работало... проблема только когда заходишь под anonymous((((

замутил поиск в гугле
pure-ftpd "550 Anonymous users can not delete files"

проблема есть и у иностранцев но так и не решена, а от сюда http://www.opennet.ru/openforum/vsluhforumID1/51857.html , вообще следует что это не баг, а фича безопасности и никак нельзя это убрать, кроме правки сырцов... Если не поможите, то переставлю фтп нафиг... или сделаю отдельные аккаунт для аплоада...
