How can I reach the server if I forget its IP Address?

Answer:

Tthere are 3 possibilities to reach the server in this case:

Possibility 1

Connect the monitor on the server and check in menue the option network info – the IP Address will be shown there

Possibility 2

Try to reach the server using its name

Possibility 3

If the server is set to pool the IP Address via DHCP Server – you can check the IP Address in the DHCP Management Software

Problem connecting to ADS server – Error Message “Domain cannot be reached”

This is usually the name resolution problem – check if the DNS server is correctly entered.

Alternatively you can try connecting by using the IP address of the KDC(domain server) – in this case euroNAS will automatically resolve the name of the domain and join without error.

Guest users are unable to log in

Problem:

User guest has been assigned to a share (under access control) – still the guests are unable to login to the share.

Solution:

Windows users are automatically trying to log in with their own local user and password and not with account guest therefore the login attempt will be rejected.

If the share is mapped with user guest - no password then the user will be able to log in.

The easiest way is to enable guest account under network - domain and workgroup when joining the workgroup or domain. In this case all users that are not known to euroNAS will be treated as guests. In guest is assigned to a certain share this users will be able to log in automatically.

FTP connection does not work

In most cases there are 2 reasons why ftp connection would not work:

  1. No users were defined to access the share – if no user is defined connection will be refused
  2. No passive port range is defined – go to service - ftp and define the range (for example 6000 - 6100)

Increasing the disk timeout values under Linux

euroNAS HA Cluster provides you the highest level of redundancy. It even protects you if one of the replication servers fail. In this case all ressources will be moved to another running server automatically.

During failover the ressources are unavailable during the failover period. In most cases OS can handle this but sometimes it is nessesary to change default timeout settings.

When connecting to Linux using iSCSI timings depend on 2 factors:

  • Timeout of the disk and
  • of the open-iscsi initiator.

You can see the current time out values of your iSCSI disk with following command:
find /sys/class/scsi_generic/*/device/timeout -exec grep -H . '{}' \;

Value can be changed by editing timeout settings in /sys – for example:
echo 180 > /sys/block/sdd/device/timeout

This setting is not remaining after reboot so putting it into a start script is recommended.

VMware ESX Server not connecting with euroNAS via iSCSI

Embedded firewall on some VMware ESX versions blocks automatically the iSCSI port 3260.

You can check this in ESX under:
Configuration -> Security Profile -> Firewall (Properties) under Software iSCSI Client
