message_size_limit = 20480000
The default when message_size_limit is not specified is 10240000 (10MB).
For complete parameter list of main.cf, see the postconf(5) man page.
$ man 5 postconf
message_size_limit (default: 10240000)
The maximal size in bytes of a message, including envelope information.
Be careful when changing message_size_limit.
message_size_limit must not be larger than mailbox_size_limit.
If message_size_limit is larger than mailbox_size_limit、you can't receive any messages.
The default of mailbox_size_limit is 51200000 (50MB).
Zero means no limit.
mailbox_size_limit = 0
mailbox_size_limit (default: 51200000)
The maximal size of any local(8) individual mailbox or maildir file, or zero (no limit). In fact, this limits the size of any
file that is written to upon local delivery, including files written by external commands that are executed by the local(8)
delivery agent.
This limit must not be smaller than the message size limit.
Let's assume there is a model `Member` and the table `members` has a column `name`.
class Member < ActiveRecord::Base end
You can use map (or collect) method as shown below.
members = Member.find(:all) member_names = members.map(&:name)
This is thanks to the definition of Symbol#to_proc in ActiveSupport as shown below.
class Symbol
def to_proc
Proc.new { |obj, *args| obj.send(self, *args) }
end
end
The code that uses map method above is equal to the code below.
members = Member.find(:all)
member_names = members.map { |member| member.name }
When you allow ftp with iptables, allowing port 21 like below is not enough to accept LIST command.
# iptables -A INPUT -p tcp --dport 21 -j ACCEPT
You need to load 2 modules ip_conntrack_ftp and ip_nat_ftp.
Edit /etc/sysconfig/iptables-config and add the following and they will be loaded automatically.
IPTABLES_MODULES="ip_conntrack_ftp ip_nat_ftp"
Then restart iptables.
# service iptables restart
Make sure the modules are loaded.
# lsmod Module Size Used by nf_nat_ftp 7361 0 nf_conntrack_ftp 13761 1 nf_nat_ftp ...(omit)

Use ssh -p option in rsync --rsh or -e option.
rsync --rsh="ssh -p 22222"
or
rsync -e "ssh -p 22222"
$ ssh-keygen -t rsa
You will be prompted to supply a filename for saving the keypair. Press enter to accept the default filename.
Then enter passphrase twice.
The keypair files below are generated in ~/.ssh.
Copy the public key file generated in step 1 to the user's home directory of remote server using scp or ftp.
$ scp ~/.ssh/id_rsa.pub user@host:
On remote server register the public key to ~/.ssh/authorized_keys using cat command and redirection.
$ cat id_rsa.pub >> ~/.ssh/authorized_keys
Modify the permissions of ~/.ssh directory and ~/.ssh/authorized_keys to allow only owner of them to read or write.
$ chmod 700 ~/.ssh $ chmod 600 ~/.ssh/authorized_keys
Permission denied (publickey,gssapi-with-mic).
In this case the log file of server side (/var/log/secure) says
Authentication refused: bad ownership or modes for directory /home/hoge
You should set home directory's permissions to 700, 711, or 755.
$ ssh -l user host
You will be prompted to enter passphrase then enter the passphrase which you specified in executing ssh-keygen command.
（Notice the passphrase is NOT a password of the user）
Copy private key file (id_rsa) to the client side ~/.ssh
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0640 for '/Users/xxx/.ssh/id_rsa' are too open. It is recommended that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: /Users/xxx/.ssh/id_rsa Permission denied (publickey,gssapi-with-mic).
Set the permissions of id_rsa to 600 and it will be OK.
For example:
If HOME is /home/pistolfly and cygwin directory is C:\cygwin, use C:\cygwin\home\.ssh.
（You can also specify path to private key file with -i option in rsync -e or --rsh options）
Edit /etc/ssh/sshd_config (server side)
Modify
PasswordAuthentication yes
to
PasswordAuthentication no
Disable root login.
PermitRootLogin no
Reload sshd as a root. Don't logout as root yet.
$ /etc/init.d/sshd reload
