This is the command to configure NTP server on a passport Nortel 8600

config bootconfig tz dst-name "ECT"
config bootconfig tz name "ECT"
config bootconfig tz offset-from-utc -60
config bootconfig tz dst-end M11.1.0/0200
config bootconfig tz dst-start M3.2.0/0200

config ntp server create a.b.c.d
config ntp server create a.b.c.d
config ntp enable true

Have an unsupported gbic module ?

enable
show interfaces status err-disabled

conf t
no errdisable detect cause gbic-invalid
service unsupported-transceiver
wr

apt-get install postfix

configurationType of mail server : Satellite System

• Mail Name : example.org (the name you want on your outbound mail)
• SMTP relay host : smtp.gmail.com
• Postmaster : I left this blank
• Other destinations : I left this blank
• Synchronous Queues : your choice, won’t impact the relaying
• Network blocks to allow relay : default (unless you know what your doing)
• Mailbox size : your choice, won’t impact relaying
• Local address : i left this as ‘+’
• Listen Address : all, your choice

Rebuild Hash

postmap /etc/postfix/sasl_passwd

Restart postfix

/etc/init.d/postfix restart

On sécurise un peu

chmod 640 /etc/postfix/sasl_passwd*
chown postfix.postfix /etc/postfix/sasl_passwd*

source ~# mysqldump -uadmin -p`cat /etc/psa/.psa.shadow` DATADASE_NAME > DATADASE_NAME.dump

On destination server create database DATADASE_NAME on domain DOMAIN.NAME with Plesk CLI /usr/local/psa/bin/database. Assign the same user and password:

destination ~# /usr/local/psa/bin/database --create DATADASE_NAME -domain DOMAIN.NAME -type mysql -passwd DB_USER_PASSWD  -passwd_type plain -add_user DB_USER_NAME -server localhost

Database creation through Plesk CLI /usr/local/psa/bin/database will update Plesk database with appropriate user and password correctly. Run the utility wit “–help” to get list of all available options. After creation it is possible to login to the database through DB WebAdmin in Parallels Plesk Panel on destination server: Domains -> DOMAIN.NAME -> Databases -> DATADASE_NAME -> DB WebAdmin

On destination server restore content of the database from the dump created on source server:

destination ~# mysql -uadmin -p`cat /etc/psa/.psa.shadow` DATADASE_NAME < DATADASE_NAME.dump 

he filtering capabilities of Wireshark are very comprehensive. You can filter on just about any field of any protocol, even down to the HEX values in a data stream. Sometimes though, the hardest part about setting a filter in Wireshark is remembering the syntax! So below are the top 10 display filters that I use in Wireshark.

1. ip.addr == 10.0.0.1 [Sets a filter for any packet with 10.0.0.1, as either the source or dest]
2. ip.addr==10.0.0.1  && ip.addr==10.0.0.2 [sets a conversation filter between the two defined IP addresses]
3. http or dns [sets a filter to display all http and dns]
4. tcp.port==4000 [sets a filter for any TCP packet with 4000 as a source or dest port]
5. tcp.flags.reset==1 [displays all TCP resets]
6. http.request [displays all HTTP GET requests]
7. tcp contains traffic [displays all TCP packets that contain the word ‘traffic’. Excellent when searching on a specific string or user ID]
8. !(arp or icmp or dns) [masks out arp, icmp, dns, or whatever other protocols may be background noise. Allowing you to focus on the traffic of interest]
9. udp contains 33:27:58 [sets a filter for the HEX values of 0x33 0x27 0x58 at any offset]
10. tcp.analysis.retransmission [displays all retransmissions in the trace. Helps when tracking down slow application performance and packet loss]

For adding a switch to the stack follow these steps:

Step 1) On the new switch give the global command: switch stack-member-number provision type

Type is the type of switch you are adding to the stack.

When adding for example a third Cisco switch to the Cisco stack, use the following command:

switch 3 provision ws3750g-24t

Step 2) Power off the new stack member

Step 3) Connect the new member to the Cisco stack using the stacking cables, 1 loop at a time.

Step 4) Power on the new stack member. The switch will come alive and will receive the Cisco IOS version from the master, when that is completed it will be ready to service network requests.

For removing a member switch from the stack use the following steps:

Step 1) Power off the stack member to be removed.

Step 2) Remove the stackwise cable from the switch.

Step 3) Issue the following command on the stack master: no switch stack-member-number provisiontype

ProFTPD allows you to create multiple virtual users by using an AuthUserFile directive. The AuthUserFile directive sets the path of a textual file containing a list of users and passwords for authentication.

Create a user file

$ touch /etc/proftpd.authuserfile

Edit the ProFTPD configuration file. (NOT etc/proftpd.include as Plesk overwrites that file regularly.):

$ vi /etc/proftpd.conf

Add this line:

AuthUserFile /etc/proftpd.authuserfile

Creat a crypted password

$ openssl passwd -crypt passwordhere

Edit the user file like this:

username:password_encrypt:uid:gid:gecos:home:shell

Example

toto:aASDFajksASa:10022:2221::/var/www/vhosts/toto.com/httpdocs/data/web:/bin/false

And finaly, reload proftpd
