Forced Upgrades Suck – Android 9 bugs

Forced Upgrades Suck – Android 9 bugs

I currently have a Samsung Galaxy Note9, which has been fantastic so far due to the long battery life, excellent camera and Android Auto. The other day my phone started warning me that it was going to upgrade, and I couldn’t prevent it only delay it. It was telling me how great the new Android 9 was compared to Android 8 and then one night it upgraded while I was asleep. Since then I’ve had several problems. Major Problem #1:…

Enable SNMP on Extreme Networks Switch

Enable SNMP on Extreme Networks Switch

The newer Extreme Networks XOS has a nice auto-secure sort of feature when you first set them up that locks down several things, one of them being SNMP. I was trying to add some X440G2 switches to Cacti and was having trouble enabling SNMP. These are the commands that seemed to work.

So you’ve locked yourself out of your Sonicwall NSA

So you’ve locked yourself out of your Sonicwall NSA

I had a funny experience where I had accidentally locked myself out of a Sonicwall NSA series firewall. I was replacing the login page with a custom one, and I had accidentally clicked OK before pasting the full HTML code. So now the login page was broken!

Google Maps is sleazy

Google Maps is sleazy

Earlier today, I was looking for a local ski shop because I wanted to buy some new boots tonight for this weekend. So I opened Google Maps, and it gave me results for several options. So I clicked on the first one and was checking out their website, they had good inventory and I opened the chat window to talk to someone there. I was asking about inventory, at which point I discovered they aren’t even in this state! Google…

icinga-web with Win2008 R2 AD/LDAP on CentOS 6.4

icinga-web with Win2008 R2 AD/LDAP on CentOS 6.4

I had a devil of a time getting icinga-web to authenticate to AD.  The howto did not work for me (I am using that example’s settings in the solution below).  I tried everything I could think of, the error I was receiving was: [fatal] Uncaught AppKitPHPError: PHP Error ldap_search(): Search: Invalid DN syntax (/usr/share/icinga-web/app/modules/AppKit/models/Auth/Provider/LDAPModel.class.php:136) (/usr/share/icinga-web/app/modules/AppKit/lib/logging/AppKitExceptionHandler.class.php:59) For me, as a workaround I opened up the LDAPModel.class.php file and right above that line in the getLdaprecord() function I added this: $basedn = “DC=domain,DC=local”; Then…

Have MRTG monitor drives >2TB

Have MRTG monitor drives >2TB

I ran into a problem where MRTG couldn’t graph disk space on arrays larger than 2TB.  This isn’t the fault of MRTG, but rather the SNMP OID I was using only went this high.  I found another set of OID’s that worked instead, but they were off by a multiple of 4.  In case anybody else runs into this problem, here is the code that worked for me.

Running IPv6 when your ISP doesn’t yet support it [solved see comments]

Running IPv6 when your ISP doesn’t yet support it [solved see comments]

I ran into an issue where a client wanted to run IPv6 internally for testing, but their ISP did not yet support it.  So we decided to use the FE00:: space and carved out a /48 for them to use.  We set each subnet internally to use a different /64, and thought all was well. Until World IPv6 day that is (June 8th 2012). Suddenly, websites (such as Google and Bing) take 30+ seconds to load.  I quickly realized that…

ASA and MRTG VPN Bandwidth monitoring

ASA and MRTG VPN Bandwidth monitoring

I came across an apparent problem in an older Cisco ASA firewall and thought I would post about it. Like many others, I wanted to monitor traffic across my site-to-site VPN’s.  I started searching and came across someone in a forum that said what the SNMP OID that MRTG needed to monitor were, so I tried: snmpwalk -v 1 -c public 192.168.1.1 1.3.6.1.4.1.9.9.109.1.1.1.1.3.1 This showed that the VPN tunnel had a strange OID below it. SNMPv2-SMI::enterprises.9.9.171.1.2.3.1.2.6340608 = INTEGER: 1 SNMPv2-SMI::enterprises.9.9.171.1.2.3.1.3.6340608…

NPS/RADIUS problem with VMware ESX 4.1 to 5.0 upgrade

NPS/RADIUS problem with VMware ESX 4.1 to 5.0 upgrade

I encountered a strange problem so I thought I’d post about it. We upgraded many VMware 4.1 ESX nodes to 5.0, and for the most part it went fine.  However after the upgrade, our wireless users couldn’t authenticate on the internal network, but the guest network still worked fine.  We were using a variety of Cisco access-points and they had worked perfectly fine with RADIUS auth before the upgrade.  I tracked down the error, the RADIUS server (now called Network…

Optoma HD700X white lines fix

Optoma HD700X white lines fix

I was given an Optoma HD700X projector for free, but it was broken.  About every 15 pixels across, there was a vertical white line.  I googled a bit and it seems that this happens fairly often on Optoma projectors (even shortly after they are bought).  It found that it was likely the main board that was in need of repair. I called Optoma, and they said the main board was $270.  Since this was free, I didn’t want to pay…
