К примеру это

text
$ sshfs root@192.168.0.5:/mnt /mnt/sshfs

понятно, паролем.
Если есть /root/.ssh/id_rsa - то по ключю, тоже хорошо.

Не пойму как сделать тоже, только если ключ называется не id_rsa, а как нибудь иначе, и не из под рута.

newzenon, сейчас к сожалению проверить не на чем, но в двух словах: если поместить публичный ключ, созданный пользователем локального компьютера, в домашний каталог root'а на удалённом сервере, то можно будет монтировать любую директорию удалённого компьютера.
Файл, по которому будет происходить идентификация, можно указать в ~/.ssh/config, задав переменную IdentityFile.

text

man ssh_config
...
 IdentityFile
             Specifies a file from which the user's DSA, ECDSA or DSA authentication identity is read.  The default is ~/.ssh/identity
             for protocol version 1, and ~/.ssh/id_dsa, ~/.ssh/id_ecdsa and ~/.ssh/id_rsa for protocol version 2.  Additionally, any
             identities represented by the authentication agent will be used for authentication.  ssh(1) will try to load certificate
             information from the filename obtained by appending -cert.pub to the path of a specified IdentityFile.

             The file name may use the tilde syntax to refer to a user's home directory or one of the following escape characters: ‘%d’
             (local user's home directory), ‘%u’ (local user name), ‘%l’ (local host name), ‘%h’ (remote host name) or ‘%r’ (remote user
             name).


             It is possible to have multiple identity files specified in configuration files; all these identities will be tried in
             sequence.  Multiple IdentityFile directives will add to the list of identities tried (this behaviour differs from that of
             other configuration directives).

абсолютно верно.
Вот пример

text
Host xyz
HostName 192.0.2.1
User user
Port 66666
IdentityFile ~/.ssh/xyz

теперь вместо указания всех этих опций можно писать просто
[console]$ ssh xyz[/console]

Дык всегда так и делаю.
У меня IdentityFile ~/.ssh/mykey_dsa прописан, только с монтированием sshfs затыки.
Вот допустим

text
Host myhost
   HostName 192.168.0.1
   Port 44535
   IdentityFile ~/.ssh/mykey_dsa
   User user

что за затыки? по ssh работает, а sshfs нет? наверняка синтаксис.

Пользователь в группе fuse, zen - альяс на сервер, tab'ом подсказки каталогов выдает, те удаленный сервер видит и каталоги видит.

05.03.2012 01:46 #235005

newzenon, ну во первых -o sshfs_debug
во вторых по scp копирует? а в mc?

05.03.2012 09:25 #235034

drBatty, -o sshfs_debug дает еще меньше иформации:

text
$ sshfs -o sshfs_debug zen:/home/john/sshfs_share/ /home/john/sshfsmount/
SSHFS version 2.3
read: Connection reset by peer
text
john@serv:~$ sshfs -o sshfs_debug zen:sshfs_share/ sshfsmount/
SSHFS version 2.3
read: Connection reset by peer

В mc по альясу - ок.
scp:

text
john@serv:~$ scp DSC08932.JPG  zen:sshfs_share/
DSC08932.JPG                                                100% 1747KB   1.7MB/s   00:01

05.03.2012 11:45 #235048

newzenon, тогда без понятия :(

05.03.2012 12:16 #235057

ой ё! smile
На сервере в конфиге /etc/ssh/sshd_config добавил:

text
# override default of no subsystems
Subsystem       sftp    /usr/lib64/misc/sftp-server

И все ок.
drBatty, -o sshfs_debug от -o debug отличается тем что отладка идет в реальном времени, те вместо подключения и выброса в cli постоянно идет отладка, все действия с удаленным каталогом выводит в консоль вот пример:
