HP 1920 switches (and others of the same kind) have a CLI mode which is highly restricted. It is possible to unlock this, providing full access to the configuration of the switch through CLI.
Log on to the CLI (SSH or Telnet) with the admin user and the password (default: none).
Type and press Enter:
_cmdline-mode on All commands can be displayed and executed. Continue? [Y/N]
Press Y to confirm.
Please input password:
Enter the password. This is a firmware-set password and is not user-defined. Depending on the firmware, try one of these:
If successful, you can now run all commands.
By default, when logging in on a HP switch in IRF mode using the web interface, you can only retrieve hardware information of the switch holding the master role. You can retrieve information for the other switches when you log on using Telnet or SSH, then type:
display device manuinfo
This will display hardware information for all chassis and slots.
RFC1918 states the following blocks of IPv4 addresses that can be used in a Local Area Network. These are "private" address ranges that do not overlap with public IP addresses.
|Network/mask||Class||First usable addr.||Last usable addr.|
|172.16.0.0/12||Class B (x16)||172.16.0.1||172.31.255.254|
|192.168.0.0||Class C (x256)||192.168.0.1||192.168.255.254|
Active Directory (AD) integrated DNS zones are not replicated by the DNS server, but replicates through the Active Directory replication mechanism, and uses the same settings for AD replication.
You can trigger replication through Active Directory Sites and Services, or with repadmin.exe on command prompt:
repadmin.exe /replicate target_dc source_dc DC=DomainDnsZones,DC=domain,DC=com
Replace parameters accordingly:
A note of caution: when installing the Fortinet SSO Agent on a server, the option to secure connections from a FortiGate with a password is enabled by default, and a random password is assigned.
You have to turn off or change the password before you add the SSO agent in your Fortigate.
There's no mention of this in the manuals, so now you know...
Cisco AnyConnect VPN client may fail on Windows 7 for no apparent reason with the following error:
A possible reason may be that Internet Connection Sharing has been enabled on one or more network interfaces (e.g. used for making a hotspot out of your laptop). Try disabling ICS, then try connecting again.
If your Samsung Galaxy S5 may not find or be able to connect to a specific 5Ghz wireless network, you may want to check which channel the network is operating on. The S5 has problems when trying to connect to DFS-channels (Dynamic Frequency Selection).
DFS-channels are basically every channel from channel 52 and up. Try setting your AP to a channel between 36-48 (inc.), and then try reconnecting your S5.
