If you have validated the disk and are sure that the disk passes you might try to add the all-generic-ide option to the boot prompt before starting the installer like this:

linux all-generic-ide

==Installing with encrypted filesystem - SME10==

In the installer for SME10, the option is given to modify the partitions created automagically. If you go into the (manual) partition edit screen then there is a tick box for the mainroot partition "encrypt data". If you tick then "update" then "done", then after allowing the installation to proceed it will ask for a passphrase. This is put in twice to verify it. Do not forget or lose this phrase else you will NOT be able to boot into your server.

Once the installation is complete, then at the beginning of every boot the system will ask for the passphrase. This means that you will always need a console on the server during the boot process.

==Yum Updates==

Line 97: Line 103:

If for some reason you can't get yum to work correctly, try:

yum clean metadata

−

or ~~possibly '~~yum clean all'

yum clean all --enablerepo=*

then

yum update

==Windows Client Computers==

{{Warning box|msg=All versions of Windows prior to versions 10 and 8.1 are unsupported by Microsoft unless you are paying them directly for support. Version 10 is a rolling edition which is continuously updated, so even early version of Windows 10 without updates are unsafe to use. Windows 8.1 is in limited "extended support" until January 20, 2023. Whatever our opinions of this situation may be, '''versions of Windows previous to v.8.1 are not safe to use on the public internet.''' We cannot support use of Windows previous to v.8.1. If you have an application that only runs on an earlier version be sure to lock it down from access outside of your network.

}}

*Windows 7 support for SME Server 8. See [[Windows_7_Support]]

Actually the SME Server 8.0 allows this windows client to reach the SME Server domain, Be aware you have to import the registery patch which you can download at http://your-sme-server/server-resources/regedit

==Reset the root and admin password==

−

=== For versions previous to 10 ===

1. Restart your server and at the beginning of the boot-up use the arrow keys to select the kernel you would like to boot into.

Line 279: Line 290:

passwd admin

Reboot your server and everything should be okay now.

=== For version 10 on ===

# At boot use ESC to bring up the boot prompt.

# At the boot prompt, use E to enter edit mode.

# Find the kernel line which starts with '''linux16'''.

# Alter '''ro''' to '''rw init=/sysroot/bin/sh'''. The rest of the line after that can be left as-is.

# Use either CTRL+X or F10 to boot into single user mode.

# Change root to the system by issuing: '''chroot /sysroot'''.

# Type '''passwd''' and follow the prompts to change the root password.

# Type '''passwd admin''' and follow the prompts to change the admin password. This and the root password must both be the same.

# Run '''reboot -f''' or ctrl-alt-del to reboot the server.

==File Size Limitations==

Line 284: Line 307:

*Backup to USB Disk

−

FAT32 only supports file size of <4GB. It is recommended that you format your external usb drives to ext3.

==External DNS==

Line 323: Line 346:

Check with

cat /var/service/dnscache/root/servers/test.com

===DNS Forwarding===

The dnscache service can be configured to forward all queries for a specific domain to an alternate server using the "domain-remote" record type in the domains db. This could be used to direct DNS for a domain to an internal DNS server connected to your network using a VPN or a custom route, or to direct your local active directory DNS to your Active Directory server, etc.

To forward all DNS for <domainname> to a specified remote DNS server (4.2.2.1 in this example):

db domains set <domainname> domain-remote Nameservers 4.2.2.1

signal-event domain-modify

As a side-effect, you can block DNS for a domain by configuring DNS forwarding to 'localhost'.

This command tells your SME to do all DNS lookups on <domainname> locally, but doesn't configure any corresponding DNS entries. Attempted lookups for the domain and all sub-domains will fail:

db domains set <domainname> domain-remote Nameservers localhost

signal-event domain-modify

* 'domain-remote' entries do not appear in server-manager; they can be managed only from the command line.

* Nameservers can be a comma-delimited list of servernames or IP addresses

==Virus Scanning==

Line 329: Line 369:

Note that early SME 7 Servers defaulted to /.

If you just leave it, freshclam should take of this as it is just log noise. See [[Bugzilla 7164]]
