Certificates

see http://wiki.contribs.org/Certificates_Concepts

How to change your certificate

Since SME version 7.1.3, the functionality to configure a Common Name in the certificate is included in the main SME packages and can be configured as follows:

config setprop modSSL CommonName www.domain.com
expand-template /home/e-smith/ssl.crt/crt
expand-template /home/e-smith/ssl.key/key
signal-event domain-modify
signal-event email-update 

see this forum thread [1] and bug report [2]

How to set expiration time

The SME self signed certificate is valid for one year, and is automatically renewed on the anniversary of the installation date of the SME server OS. To specify how long your SME certificate will last for, do the following:

cp /etc/e-smith/templates/home/e-smith/ssl.crt /etc/e-smith/templates-custom/home/e-smith/ssl.crt
nano -w /etc/e-smith/templates-custom/home/e-smith/ssl.crt

change the value for KEYLIFEINDAYS on the first line to the number of days the certificate will remain valid for eg 1826 for 5 years.

Save & exit by pressing the following keys at the same time

ctrl o
ctrl x

Create a new self signed certificate, with the longer validity period. Replace the filenames below with the correct file/key names applicable to your server.

rm /home/e-smith/ssl.crt/servername.domain.com.crt
rm /home/e-smith/ssl.key/servername.domain.com.key
rm /home/e-smith/ssl.pem/servername.domain.com.pem
signal-event post-upgrade
signal-event reboot

Install the new certificate into your browser.

create missing group and set gid

If a specific sme group or linux group is missing, you can create it again. see bugzilla:7932#c48

groupadd -g 102 -o apache
rpm --setugids --setperms rpm1 rpm2

where 102 is the correct gid of apache group, adapt it to the right setting where rpm1 and rpm2 are valid rpm but broken due to the lack of apache group during installation or upgrade

RPM's

Command	Explanation

rpm -Va	capture any damaged/incomplete rpms - but will also show lots of configuration files, which you of course expect to be modified.

Restore all permissions and ownership

If you want to restore all permissions and right ownership of rpm, you can do this in a root terminal. See bugzilla:6851#c15

for f in $(rpm -qa); do echo $f; rpm --setugids $f; done
for f in $(rpm -qa); do echo $f; rpm --setperms $f; done

YUM'ing and repositories

Command	Explanation
yum install <packagename>	installs packagename & any package it may need
yum remove <packagename>	removes packagename
yum list updates	list updates to any installed package
yum list available	list available packages in all repos not already installed
grep <reponame>	list available packages -shows only from repo name

/sbin/e-smith/audittools/repositories	show all repositories and if they are activated or not
db yum_repositories show <reponame>	show properties of the repository <reponame> (you may use TAB to auto-complete your command line)

Restoring Default Yum Repositories

	Note:
	If you have problems with your yum setup you may have entered incorrect repository values. Remove the current values and restore the original setting with these commands

cd /home/e-smith/db/
mv yum_repositories yum_repositories.po
/etc/e-smith/events/actions/initialize-default-databases

Now you have a clean install, you can re-add 3rd party repos as described above

signal-event yum-modify

and check if you can update your server

yum update

LDAP

Display LDAP parameters

you can display LDAP parameters, either by the server-manager or by the command line :

ldapsearch -x -h localhost -s base |grep 'dn'

Log

Parse Log to find errors

When you want to test the SME Product it can be useful to see what it occurs This CL can help you, but you should read the entire log

grep -iE "uninitialized|WARNING|ERROR" /var/log/messages

of course this is for the /var/log/messages

or if you want to parse all log

grep -iE "uninitialized|WARNING|ERROR" /var/log/*

	Note:
	you have now a tool in your hand to parse logfile : Audit_Tools#logcheck. You should be aware that tool is here to help to find errors in the development side of the SME Server and thus you could have a lot of false positive

Mail

see Email

check blocked email address by the server

grep -i 'blocked email address' /var/log/qpsmtpd/current

maximum email size

Email#Set_max_email_size

Spam filter with Server-Manager

Using the Server-Manager Configuration/E-Mail panel, adjust the settings to these reasonable defaults.

• Virus scanning Enabled
• Spam filtering Enabled
• Spam sensitivity Custom
• Custom spam tagging level 4
• Custom spam rejection level 12
• Sort spam into junkmail folder Enabled
• Modify subject of spam messages Enabled

spam retention in junk mailbox

The server will automatically delete old spam in the junkmail folders after 90 days. You can control the number of days old spam is kept with the following commands. Where 15 is the number of days you want to keep messages, do...

db configuration setprop spamassassin MessageRetentionTime 15
signal-event email-update
svc -t /service/qpsmtpd

then config show spamassassin

Mail Statistics

See Mailstats for details on the mailstats package.

yum install --enablerepo=smecontribs smeserver-mailstats

Whitelist and Blacklist

If mail comes in and it is misclassified as spam, you can add the sender to the whitelist so that future messages coming in from that sender are not filtered. Conversely, you can add a spammer to the blacklist so you never see their spam again. Add senders (or their entire domains) to the global whitelist (or blacklist) with commands similar to these (as root):

db spamassassin setprop wbl.global *@vonage.com White
db spamassassin setprop wbl.global *domain2.com White
db spamassassin setprop wbl.global user@domain3.com White
db spamassassin setprop wbl.global spammer@spamdomain.com Black

expland template and save the configuration to the database

expand-template /etc/mail/spamassassin/local.cf
svc -t /service/spamd

You can view the lists with this command:

db spamassassin show

MySQL

There appears to be no password set for the MySQL root password, but this is not true. If you are logged in to the SME Server shell a special mechanism is in place to log you in with MySQL root privileges without prompting you for the password.

The MySQL root password for SME Server is a 72 character random string generated during installation of SME Server. You should never change the MySQL root password as this will break your SME Server configuration. How to login as MySQL root user? describes how to access MySQL with root privileges on SME Server.

For more informations you can see the MySQL page

Login as MySQL root user

To login as MySQL root user, simply type 'mysql' at the SME Server shell, this will log you in with root privileges. the mysql admin password is a random password generated which can be find

• /root/.my.cnf
• /etc/ldap.secret

do not modify these files.

if you need to call the mysql password in a script you can invoke this bash variable

PWD=$(cat /etc/ldap.secret)

Create a Database and its User

Create a new MySQL database (In this example the database name is databasename. Change databasename, username and password with your own choices as required)

Login as root and issue the following command:

mysql
create database databasename;
grant all privileges on databasename.* to username identified by 'password';
flush privileges;
exit

Remove a database

Get access to the SME Server shell and MySQL and issue the following command:

drop database databasename;

Replace databasename with the name of the database.

Remove a user

Get access to the SME Server shell and MySQL and issue the following command:

USE mysql;
DELETE FROM user WHERE user = 'username';
FLUSH PRIVILEGES;

Replace username with the username you wish to delete.

	Tip:
	mysql_setpermission is a command line menu driven utility that can assist in MySQL administration.

Other useful MySQL commands:

show databases;

list all available database.

SELECT user FROM mysql.user;

display a list of the MySQL users

SHOW GRANTS FOR 'user'@'localhost';

list the privileges granted to the account user

GRANT ALL PRIVILEGES ON *.* TO 'new_dba'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;

give all rights on all databases for new_dba user

GRANT SELECT, UPDATE, INSERT, DELETE ON database.* TO 'new_user'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

give all rights on database for new_user

mysqladmin drop databasename;

will let you destroy a database. Use with care. Use 'mysqladmin --help' for all available options.

Password

Password strength

First a warning - Far too many systems out there have weak passwords and they will be broken into. Educating your users on the necessity of strong passwords is the best option. If that fails, here is how you change the password strength checking from 'strong' to 'normal', which was the setting in previous versions of SME. Be careful to use the exact capitalization.

config setprop passwordstrength Admin normal
config setprop passwordstrength Users normal
config setprop passwordstrength Ibays normal

It is also possible, but strongly discouraged, to disable password strength checking by setting to 'none'

none   : no check is performed on the password
normal : the password must be composed of at least seven characters with uppercase and lowercase letters, numbers and non-alphanumeric characters
strong : the restrictions are the same as for the normal level, but in addition, the password is verified by cryptlib which ensures its actual complexity

Change Password Users by the command line

If you want to change password to your users by the command Line instead of the user panel of SME Server you can do it like this.

perl -e "use esmith::util;esmith::util::setUserPassword( 'username', 'password');";  /sbin/e-smith/signal-event  password-modify username

run it for each user separately and replace

username

and

password

with the appropriate values for each of your users.

Signalling events : Signal-event

The signal-event program takes an event name as an argument, and executes all of the actions in that event, providing the event name as the first parameter and directing all output to the system log. It works by listing the entries in the event directory and executing them in sequence. So for example, the command:

signal-event console-save

will perform all the actions associated with the console-save event, which is defined by the contents of the /etc/e-smith/events/console-save/ directory. This is exactly what the console user interface does when you select save at the end of the console configuration wizard.

& to check it's running

sv s /service/squid

db command

	Note:
	SME Server comes with the most used parameters set as variables in its internal configuration databases. These variables are used to store values to be used in the final configuration files. Please, read the SME_Server:Documentation:Developers_Manual:Section2 to understand the template and database process.

you can see this page of the wiki DB_Variables_Configuration

Setting db variables to default values

	Note:
	Use of 'config' is a shorthand version for 'db configuration' and therefore only works with the configuration database

Any db variable that has a default value can be reset to the default by deleting the variable entirely, then re-initializing the default database values as follows:

config delprop <key> <prop>
/etc/e-smith/events/actions/initialize-default-databases

Delete a property value

To delete the property

db accounts delprop <key> <prop>

Reset a property value

To reset to an empty value

db accounts setprop <key> <prop> ''

	Warning:
	Database parameters are case sensitive so take great care when typing at the server shell because no error messages are given should you make a mistake.

Give a shell access to "user"

db accounts setprop user Shell /bin/bash
signal-event user-modify user

General Service Handling

• start

sv u /service/servicename

• stop

sv d /service/servicename

• restart

sv t /service/servicename

	Tip:
	you may use TAB to auto-complete your command line

All other linux common way to start or stop services are also valuable

/etc/init.d/servicename start/stop/status
service servicename start/stop/status

Example

Restarting:

sv t /service/httpd-e-smith

allow a service to start for a particular time

If your package implements a server or daemon, you will probably want it to be started automatically when the system boots. The SME Server boots in runlevel 7, so you can get an idea of the startup processes by listing the contents of /etc/rc.d/rc7.d.

These are similar to the init scripts you may be familiar with from other Linux systems, with one important difference. Instead of pointing to scripts within /etc/rc.d/init.d, all of those init entries are links to /etc/rc.d/init.d/e-smith-service. This is a wrapper which checks the configuration database to see if the service is supposed to be running and if so, starts the service from /etc/rc.d/init.d/whatever.

So for example, you might have:

S90squid -> /etc/rc.d/init.d/e-smith-service

The e-smith-service script looks up the name it was invoked with (S90squid), drops the prefix (leaving squid), checks the configuration database for the "squid" service, then if it's supposed to run, does:

/etc/rc.d/init.d/squid start

• with this way SME's knows how to/if start the service at startup

config set myapplicationname service status enabled

cd /etc/rc.d/init.d
ln -s /path/to/myinitscript myapplicationname

We are creating a symlink of the original startup script with a new name (the point is that myapplicationname must be identical to the service name above)

cd /etc/rc7.d
ln -s  /etc/rc.d/init.d/e-smith-service SXXmyapplicationname

we create a symlink to e-smith-service startup script with a name where: S tells SME to start XX are numbers

You can decide when to start the service myapplicationname, but you should not start something that need the network before the network itself is up and running. Therefore you can see the content of /etc/rc7.d and see which scripts are needed to execute your new startup script

signal-event remoteaccess-update
service myapplicationname start

Creating or deleting a service

• Creating and starting service

ln -f -s /etc/rc.d/init.d/e-smith-service /etc/rc7.d/S98popfile
/sbin/e-smith/db configuration set popfile service status enabled
/sbin/e-smith/signal-event remoteaccess-update
service popfile start

• Deleting and unregistering service

service popfile stop
sleep 3
rm -f /etc/rc7.d/S98popfile
rm -f /etc/rc.d/init.d/popfile
/sbin/e-smith/config delete popfile
/sbin/e-smith/signal-event remoteaccess-update

Create a service with db command and set network access

DB_Variables_Configuration#Additional_information_on_customizing_iptables

Create a custom-named service definition in the configuration database.

db configuration set <servicename> service

Apply your desired firewall restrictions to any existing SME 'service' or to a custom-named service that you have created. Combine a custom-named service with port-forwarding to create customized firewall rules.

db configuration setprop <servicename> TCPPort <portnumber>
db configuration setprop <servicename> TCPPorts <portnumbers> # Ranges of ports are defined with a : not a -
db configuration setprop <servicename> UDPPort <portnumber>
db configuration setprop <servicename> UDPPorts <portnumbers> # Ranges of ports are defined with a : not a -
db configuration setprop <servicename> status enabled|disabled
db configuration setprop <servicename> access public|private
db configuration setprop <servicename> AllowHosts a.b.c.d,x.y.z.0/24
db configuration setprop <servicename> DenyHosts e.f.g.h,l.m.n.0/24

Effectuate the changes you have made

signal-event remoteaccess-update

SSH

Enable SSH

• Enable ssh access (the lazy not-so-secure way, but I am assuming for this testing/dev scenario that your external IP is really a local address behind a router)

db configuration setprop sshd status enabled
db configuration setprop sshd PermitRootLogin yes
db configuration setprop sshd acccess public
db configuration setprop sshd PasswordAuthentication yes
/sbin/e-smith/signal-event remoteaccess-update

• Allow ssh in public or private mode : public= all internet private= only your network

db configuration sshd access public
signal-event remoteaccess-update

Access to the terminal of your remote sme

ssh root@ip-sme-or-remote-hostname

or

ssh -pX root@ip-sme-or-remote-host (X is the port listened by ssh service)

Note:

you need to forward in your router the port 22 (or whatever you decide) to your internal sme's ip and allow ssh in the server-manager with the root login and Password Authentication (Security/Remote Access menu). You can enhance security by disabling the root connection : Allow administrative command line access over secure shell NO Keep in mind that you need to set the service to public access (entire internet) if you want to be accessible by ssh outside of you network (see the Denyhosts contrib for banning hosts which failed too many login attempts to your ssh deamon.)

Execute or run a command over ssh to a remote server and auto disconnect after quit

ssh -t root@ip-sme-or-remote-hostname command

where 'command' is the program or command to run. An example could be:

ssh -t root@192.168.1.5 top

Access to the server-manager through SSH

We can access to the server-manager of your remote SME Server by SSH with a tunneling protocol initiated by "ssh -L". This command has to be done by a superuser in a Terminal like if you want to be connected to your SME Server by SSH.

	Note:
	We assume that ports are forwarded in your router to your sme internal IP (443 and 22) and the root user is allowed to access by ssh to the server.

Do this in a root terminal of your Linux computer outside of your network

ssh -L 443:localhost:443 root@your-static-external-network-IP-or-host.dyndsn.org

host.dyndsn.org could be a free service as dyndns.org or noip.com

Keep the terminal open, Then you need to use this specific URL in your WEB Browser to go to the server-manager

https://localhost/server-manager

	Tip:
	It is possible to use putty if you are afraid about some commands in a terminal, you can find a lot of examples by typing this in google tunneling by putty

Access with non standard ports

In certain cases which you are not root on the local computer, you can not redirect port < 1024, so you have to use port > 1024 as the example below.

ssh -L 9443:localhost:443 root@your-remote-ip -p 22

9443 : local port
443 : remote https port
your-remote-ip : the remote host (could be an ip or a domain name)
22 : this is the port where the ssh server is listening, you can change it in accordance with the remote server

Keep the terminal open, Then you need to use this specific URL in your WEB Browser to go to the server-manager

https://localhost:9443/server-manager
