The loss of your Drobo’s shared resource settings (i.e., the volumes do not show) can be caused when the server service in Windows starts up before the iSCSI Initiator service does. The server service needs the iSCSI service to have already started file shares.
To fix this issue, open a command prompt, type: “sc config LanManServer depend= MSiSCSI” and press Enter.
via Drobo Support.
WRONG WRONG WRONG. If you run the above command, the LanManServer (Server) service will fail to start.
The correct command for adding the dependency on the iSCSI service (on a stock Win2K8 box) is
sc config lanmanserver depend= SamSS/Srv/MSiSCSI
Running the other command deletes the original dependencies of the Server service and replaces them with only MSiSCSI.
Correct answer via User Error.
A nice explanation of EDGE/3G/4G/HSPA/LTE
Network Symbols Explained
*As I’ve only had AT&T, I can only speak for how it is with them.*
Firstly, AT&T stock LTE phones always showing 4G is a lie. It will show 4G wether you have HPSA or HPSA+. Technically 4G doesn’t even exist. It’s a marketing gimmick.
According to AT&T here is how the symbols work:
- E(dge): GSM – The slowest of the slow.
- 3G: HSPA or UMTS – High Speed Pack Access and Universal Mobile Telecommunications System
- 3G(+): HSPA+ – An upgrade to the HSPA protocal. This is your average network.
- 4G: HSPA+ – Tower upgrade. Enhanced backhaul. (essentially the same tech as 3G+)
- 4G LTE: LTE – Long Term Evolution. On LTE you should typically expect speeds no less then 20mbps.
If you are using the RumRaider ROM (as of 1/3/’12) your symbols will appear as:
- E – E
- 3G/3G+ – 3G
- 4G – H
- 4G LTE – 4G
via General Knowledge Thread – xda-developers.
Bell/Telus/Sprint/Verizon also operate an older 3G network using CDMA2000 technology. 1x, EV-DO and 1xEV refer to CDMA2000 extensions for enhanced data.
Gotta love when marketing brings “technical” terms to the masses.
Being a long-time Ubuntu/Debian user, I’m used to editing the good ol’ /etc/network/interfaces file to configure network interfaces.
Recently, trying Arch Linux, I discovered that networking isn’t always that simple.
Most basic system parameters in Arch are configured in the /etc/rc.conf file. However, that file is limited to configuring one static wired ethernet connection.
In order to configure multiple interfaces, you need to install the netcfg package and create profiles for each NIC in /etc/network.d :
There are some examples provided, however none of them mention how to set a custom netmask or multiple DNS servers. So here are my two network profiles:
interface 1 (/etc/network.d/interface1-static)
CONNECTION='ethernet'
DESCRIPTION='Static IP WAN'
INTERFACE='eth0'
IP='static'
ADDR='172.32.24.108'
GATEWAY='172.32.24.1'
DNS=('172.16.24.1' '172.16.24.3')
interface 2
CONNECTION='ethernet'
DESCRIPTION='Static IP LAN'
INTERFACE='eth1'
IP='static'
ADDR='192.168.2.80'
NETMASK='255.255.254.0'
Once the profiles are created, go back to the /etc/rc.conf and make them activated at boot. The values for the NETWORKS array are the two files previously created in /etc/network.d:
# Enable these netcfg profiles at boot-up. These are useful if you happen to
# need more advanced network features than the simple network service
# supports, such as multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
#
# Network profiles are found in /etc/network.d
#
# This requires the netcfg package
#
NETWORKS=(interface1-static interface2-static)
# -----------------------------------------------------------------------
# DAEMONS
# -----------------------------------------------------------------------
#
# Daemons to start at boot-up (in this order)
# - prefix a daemon with a ! to disable it
# - prefix a daemon with a @ to start it up in the background
#
# If something other takes care of your hardware clock (ntpd, dual-boot...)
# you should disable 'hwclock' here.
#
DAEMONS=(hwclock syslog-ng net-profiles sshd netfs crond dbus @cups kdm)
