USB to Serial Adapters

November 12th, 2009

One large issue I have run into with installing Windows 7 on my laptop was that my USB to Serial adapter that I need to use a cisco console cable and that no longer worked.  Apparently, from a little bit I have read on the web, most of the manufacturers of these devices use a chipset from Prolific.  I pulled the driver from this site:

Once I got that installed, all was well again and I was able to connect to switches and routers via the console cable.  Yay

Novell Teaming: Some gotchas

November 13th, 2008

Yesterday I fired up a new ESXi host and began to lay down a SLES guest.  I wanted to install Teaming (minus) Conferencing.  The first gotcha I ran into was that the 20 user starter pack isn’t quite like previous starter packs for other products which worked right out of the box.  To get a license key, you have to fill out a form, get a call from a Novell rep, and they would put the order in.  So, in 5-7 business days, I should get my license key.

As an aside, I don’t see the point of having to wait, or even talk to anyone at all.  All this process does is put up a barrier for people who are even vaguely interested in the product.  In my opinion, it’s a bad policy.  Novell needs to get any of their branded software into the hands of anyone who might even want to try it.  Making anything even remotely exclusive just can’t help them try to stay relvent in the market place.  You can put application virtualization in the same boat.  Time bombed or limited software is something Microsoft might be able to get away with, but that old thinking probably won’t help you unless you’re that 800 pound gorilla and don’t need inovative ways to compete.

The next gotcha involves licensing as well.  The 60 day evaluation license apparently isn’t named correctly.  Whatever the file you download is called, it has to be renamed to license-key.xml.

Next up, the option to install the DB may or may not work.  It didn’t for me, although I’m not entirely sure why.  See this post on the forums to get past that issue.

Finally, the initial install screen didn’t scale correctly for me.  There was an absurd amount of empty space between the dialog and the buttons.  I had to change the resolution to 1024×768, enable remote administration, and use tightVNC to be able to see the installer.

Now have the product installed.  I’m starting to work my way though customizing and getting things set.  I’ll report back with any updates.  Also, ESXi absolutely rocks.  I can only imagine how cool being able to use vmotion would be.

Suse cron docs

I have to read up on this.  The cron structure in Suse isn’t very straight forward.

Unity messages cut short

September 4th, 2008

From Cisco.com…..

MGCP gateway

Cisco Unity is unable to record messages for more than 50 seconds because the receive-rtcp timer times out on the MGCP gateway and the call gets disconnected. Disable the timer with these commands in the MGCP gateway in order to solve the problem due to disconnect of the call.

MGCPGateway(config)#no mgcp timer receive-rtcp

This command turns off the RTP RTCP receive timeout interval at the MGCP gateway.

MGCPGateway(config)#voice rtp send-recv

This command is used in order to establish a two-way voice path when the Real-Time Transport Protocol (RTP) channel is opened.

I’ll have to do this after hours and do some testing to see if the length of a voice mail will be extended.

Free alternatives

July 7th, 2008

I’ve spent a good portion of the morning figuring out a replacement for Adrem.  I’ve settled on a cobbled together solution of VNC for NetWare and a spiffy little program called Terminals.  It’s not the ideal solution, but it will get the job done for now.  A word to the wise, bare VNC will whip your security types into a frenzy, so watch your ass!

VNC for Netware is as easy as dumping the contents of the zip file onto the sys volume and running the following commands.

load vncpass

load vncsrv

The other benefit going this route, is that Terminals will allow for “Favorites” of servers, “tabbed browsing”, and multiple protocols so I can add all my servers to this one utility.  Still not as nice as Adrem, but it has features that the AWOL freecon didn’t have.

How to enable SNMP on SLES 10

June 11th, 2007

It seems that without fail, whenever I try to install or configure something on Linux, it generally turns into a failure the first time around. I tend to open up the documentation, get distracted because I just want to get it installed so I can mess around with it, and just try to get it going by shooting from the hip. I always end up going back to the docs or finding something on the net(do we still say that? I didn’t get the memo) that explains whatever issue I’m having in plain english. Call it a bad habit, but it’s how I learn.

At any rate, after beating my head on my desk trying to get snmpd running and configured properly on a SLES 10 box for cacti, I stumbled on this TID:
