I asked for a certificate on Thursday. Come Monday morning, still no response.

So I sent a follow-up email and CC'd the project management team.

Within the hour, I got the certificate.

Just installed it, and it's working perfectly. Also the weekend upgrades went well after I suggested that the upgrade may have changed the file structure, which would be why the backup restore didn't work. My counterpart took that suggestion, set up the folders needed and stuffed them with goodies, and it's all good.

:bole:

I'm totally on a roll today. I just finished doing my health benefits enrollment and I'm squaring away my Tipping Point classes in December. AND I'm going to a vendor-provided luncheon at a really nice steakhouse next Tuesday, just found out.

Damn, it feels good to be a gangsta.

Sometimes, you solve a network problem by solving a Linux config problem.

If there's a delay between entering your username and being prompted for your password on a Linux box, turn off GSSAPI and reverse DNS lookup. BAM.

Just got a big, big issue with our guest wireless network cleared up.

YESH

PROTIP: If the device doing a DNS capture is blocking DNS traffic to itself, that block will interfere with the function of the DNS capture, even if the vendor insists it's not his gear that's misconfigured.

So .... the block is blocking... sounds like working as intended!

The block was blocking everything, even the block. :problem?:

deny ip any any log is secure, and provides full forensic information.

Found and cleared up a networking issue, I noticed my SSH sessions were a little sluggy so I did some digging and found the traffic between a bunch of our routers was loosing ~30% of it's traffic!  Found the switched port that was the issue even though there were no indicators like errors, drops, etc on the port or the port it was connecting to.  Moved spanning-tree to one of it's alt ports and it's good to go now.  About half an hour into the process I had 3 other people notice stuff was slow and they weren't happy with my broken network and no thanks for finding and fixing the issue quite quickly (even without any network monitoring software).

We need an "I did something bad and I am ashamed" section, cause when I moved off the port that was working poorly I moved it off to a port... a port that was blocking a very important vlan and killed a bunch of stuff.

Like you wouldn't believe!!!  It's kind of a weird cloud setup. We have 40+ areas using the same single IP space, and I am the only one who does up-keep on it in my spair time, and it's kinda a hack job right now just cause I don't have time :-[.

I would have been fine if we were doing PVST, but we have way to many vlans for that so the MSTP got me :-(
