Remote System Installation

This manual is intended primarily for users who do not have adequate knowledge of Linux systems needed to the self-reliant local installation or for those who do not have enough time to accomplish a self-reliant installation. The following approach shows you how to configure the installation so that it can be remotely accomplished by our technical support.

Preparation

Insert the installation CD into the drive and boot from it. There are two ways to boot from the cd.

  • 1. way - you set the booting in BIOS from the CD. In this case, booting will always be performed from the CD, even after potential restarts. This may be during the installation of ISPadmin system a little problem, because after the primary installation from the CD, it is necessary to boot from HDD and perform another configuration, and if the system still boots from the CD, you have no other choice but to contact an authorized person at the server to remove the installation CD from the drive and consequently boot the system from the hard disk. Some CD drives opens after the command "eject the cd" and after the restart of the system, the CD will not drive back (such as mechanics that are used in laptops). In this case everything is OK and the system will boot itself from HDD after the restart. However, some servers have standard CD / DVD drives, which after the restart of the server drive the CD back again and boot from it, this is undesirable and it requires operator intervention.
  • 2. way - when the server starts, press the key that will get you to the BootMenu (usually F11, but it can also be a different one. It is listed during the start of the server.). Then select to boot from the CD. This way it is arranged that the first booting is done from the installation CD and after the restart of the server the booting settings from BIOS is used again, where the classical boot from hard drive will be set. In this case, no operator assistance of the server is required.

After booting of the system, the preparation of the installation environment is performed and the command line where you can start working is displayed.

Setting up of the Internet connection

The only thing you need to set is the connection to the network. Set the address, so that server is accessible from the Internet. This means that either you will enter the public IP address (two string bags, one to the internal network and one out) or when the machine is placed in the internal network, change the ports 22, 80 and 443 on the internal network card with a private address to a public IP address.


Example for setting the IP address and mask

ifconfig eth0 81.13.51.211 netmask 255.255.255.0


Example of setting the default gateway

route add default gw 81.13.51.193

Checking the connections

We can check the correct result via the ping command, for instance on the server nix.cz (195.47.235.3), which verifies the functionality of communication on the Internet. If the result of a ping is successful, you can proceed to the last point, which is the contacting of our technical support with the request of accomplishment the remote installation.

ping 195.47.235.3 
PING 195.47.235.3 (195.47.235.3) 56(84) bytes of data. 64 bytes from 195.47.235.3: icmp_seq=1 ttl=93 time=0.905 ms 64 bytes from 195.47.235.3: icmp_seq=2 ttl=93 time=0.762 ms 64 bytes from 195.47.235.3: icmp_seq=3 ttl=93 time=0.865 ms --- 195.47.235.3 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 0.762/0.844/0.905/0.060 ms
### sent packets have returned, so we made sure that the Internet connection is fine

Check of the IP address and default gateway settings

ifconfig 
eth0 Link encap:Ethernet HWaddr 00:E0:4C:62:3B:9F inet addr: 81.13.51.211 Bcast: 81.13.51.192 Mask:255.255.255.224 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:70239 errors:0 dropped:0 overruns:0 frame:0 TX packets:73398 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4774126 (4.5 MiB) TX bytes:13479965 (12.8 MiB) Interrupt:16 Base address:0xe800
### in the excerpt we see the currently configured IP address and network mask

Check of the default gateway settings

route -n 
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.20.100.0 0.0.0.0 255.255.255.248 U 0 0 0 eth0 0.0.0.0 81.13.51.193 0.0.0.0 UG 0 0 0 eth0
### designated address, so the one that routes 0.0.0.0. represents our default gateway

Contact us

Now it remains only to send the configured IP address on email support@ispadmin.eu or call on +420 212 220 480. Thereafter, the remote installation implementation ensures our technical support.

When the installation is complete, it is still needed to figure out two domain names (for the user interface and the admin interface), for which you create DNS records pointing to the server with the installation. Ideally, you send the selected names (at least third-order domain) directly with the IP address of the server. This way you will speed up the time when you will be able to log into the web interface of the system via the symbolic addresses instead of the classical IP addresses. Examples of the suitable domain names:

  • Administrator interface:
ispadmin.yourcompany.com, admin.yourcompany.com, management.yourcompany.com…
  • User interface:
client.yourcompany.com, customer.yourcompany.com, portal.yourcompany.com, support.yourcompany.com…
