LG Nortel – Phone Auto Answering Calls

Had a random issue, an LG Nortel phone was auto answering calls on speakerphone. It apparently is a ‘feature’.

On the screeen next to the phones name it had (H) instead of (T).
So it said ‘Andrew (H)’

How to fix.

  • Press. Trans/Pgm
  • Option 1 (Ring)
  • Option 2 (Answer Mode)
  • Select T(2)
  • Press Hold/Save to save it.

Thanks to this pdf: LG Quick Reference Guide 8000 Series.pdf

For pointing me in the right direction.

Set Intercom Answer Mode
This determines how your Station will ring when receiving an intercom call

  • Press TRANS/PGM button
  • Dial 1 3 and select
  • 1. for Hands free (Auto answer after a BEEP tone)
  • 2. for Tone ring
  • 3. for Privacy announce (Auto Answer but you must pick-up the handset to talk)
  • Press HOLD/SAVE button or the OK button

 

Endian DHCP stopped and failing to start on 3.0.5beta1

TL:DR Updated Endian this morning, and the DHCP service failed to start. Turns out having a 2nd DNS server set in the Web GUI doesn’t correctly write to the dhcp.conf file. Solution. Remove 2nd DNS server or manually add a comma (,) into the config file using nano.

In the Web GUI under “Status -> System Status”

The DHCP server was shown as “Stopped”.

Manually starting from the shell also failed.

‘service dhcpd start’

A quick look in the logs:

‘cat /var/log/messages’

Luckily the log points us in the right direction.

/etc/dhcpd.conf line 21: semicolon expected.
Feb 25 10:22:51 endian dhcpd:         option domain-name-servers 192.168.0.3 192.

In the Web GUI if I remove the 2nd Name server, all is well, the service starts up and the log shows requests being received.
When I add it back in, it fails to start again.

When I add the comma in using nano, I’m able to manually start the service.
Although I’m sure it will break if any changes are made to the web gui.

Update: It appears that this bug has been around for a few days, and is reported: https://jira.endian.com/browse/UTM-1388

Bridged ADSL modem over VLAN Router on a Stick

TL;DR: Bridged ASDL modem over VLAN – yes it can work!

The problem:
x86 Router (Endian) has run out of physical network cards, but more WAN ports are required, can we do something with a ‘Router on a stick’ and use a VLAN aware Switch?

We can do this in a ‘double NAT’ style configuration, but can we do it in a bridged mode configuration. It seems that we can in fact. However I’m using a L3 switch (Dell 6248) I have tired in the past to use a HP PS1810-8G Switch (J9833A) without successful (granted I didn’t spend too much time on it).

Xero API pyXero and Anaconda Python

Personal TL;DR notes on getting this to work, not a tutorial.

Download Install Anaconda
– At the time of writing it didn’t create Windows Shortcuts, fix this with openning cmd as admin

‘c:\Anaconda2\scripts\conda.exe install menuinst’

Agree to Updates

‘c:\Anaconda2\scripts\conda.exe install -f console_shortcut ipython ipython-notebook ipython-qtconsole launcher spyder’

Agree to updates.

Now there should be shortcuts in:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Anaconda2 (64-bit)

Now onto Xero

  • git clone https://github.com/freakboy3742/pyxero.git
  • Open up Anaconda Prompt (Anaconda2x64)
  • cd into folder with git of pyxero
  • use command: python setup.py install
  • pip uninstall oauthlib
  • pip install oauthlib==0.7.2

The last two commands fix the error: ImportError: No module named jwt.algorithms

Again these are personal notes, not a full blown tutorial.

 

Dell Powerconnect 5424 SNMP web management issue

Just ran into a strange issue when configuring a SNMP community on the web interface. Alas it was broken.

2016-01-19 10_36_26-ATKOSD22016-01-19 10_36_26-ATKOSD2

And clicking on “add’ results in an error

‘Access Error: Request Entity Too Large’2016-01-19 10_36_47-ATKOSD2
An easy fix is to stop being lazy and CLI into the switch and fix it.

The command:

snmp-server community public su 192.168.0.5

2016-01-19 10_39_23-Greenshot image editor

And look, it works for us. Now you can webconfig until your heart is content.

2016-01-19 10_38_07-ATKOSD2

Don’t forget to write your switch config changes.

Issue with WordPress Autoptimize Cache filling up cPanel Server Space.

Issue with Autoptimize Cache filling up cPanel Server Space.
As a temporary fix, just run a cron to delete all the cache files once an hour.
– I have only seen this issue with a Multisite install, but I haven’t had a problem on single site installs.

Log into cPanel go to CRONs

Under ‘Add a New Cron Job’ use the following settings:

Minute: 7
Hour: *
Day: *
Month: *
Weekday: *

Under the command section you need to first work out where your WordPress site is installed,
usually under cPanel it is under /home/[your_cpanel_username]/public_html/

Then you need to add the folder of the Autoptimize Cache folder, so the entire thing looks something like this:

/home/[your_cpanel_username]/public_html/wp-content/wp-content/cache/autoptimize/

Add the command rm -r at the start, put it all together and you have the right command:
!IMPORTANT! – The command rm -r will delete everything in the folder, if you get the path to the folder wrong, you could delete your entire website. You have been warned!

rm -r /home/[your_cpanel_username]/public_html/wp-content/wp-content/cache/autoptimize/

 

2016-01-14 10_20_04-cPanelX-CronJobs

So what we are doing is just at 7 minutes past the hour, of all hours, of all days, of all months, each weekday (that’s how you read the * in the cron) we delete all the files in the folder that we told it too.

check_mk_agent over SSH Host key verification failed

Service discovery failed for this host: Agent exited with code 255: Pseudo-terminal will not be allocated because stdin is not a terminal. Host key verification failed.

Current Setup: Ubuntu 14.04 running OMD

Solution: Running the ssh command from the OMD user appears to fix the problem by allowing them into the known hosts list.

Here’s how:

[email protected]_vm:~$ sudo su
[sudo] password for linuxuser:
[email protected]_vm:/home/scadmin# su [omd-site-name]
ubuntu_vm[[omd-site-name]]:~$

then run your remote command eg:

ubuntu_vm[[omd-site-name]]:~$ ssh -l root -i /etc/check_mk/check_mk.key [ip]

It will ask to save the host to the known hosts, type yes and enter. It should then output the status from the check_mk agent.
