We have some 2008 Windows servers that keep disconnecting RDP session attempts with a RESET before the connection is complete. We have taken a lot of Wireshark traces from different sources to several different machines. On most of the connections we see a SYN come in, the server responds with a...

I don't have a script but I've used a program called "Ping Tester Pro" that will ping with different sizes, intervals, timeouts and record failure times. You can schedule a time for it to stop/start and you can export the results to a spreadsheet. As ping tools go, pretty cool

In a TCP conversation, if a server initiates a disconnect by sending a FIN to the Client, the server enters FIN-WAIT-1 state. If the Client then sends an ACK he enters the Close-Wait state and the server is now in FIN-WAIT-2 state. At that point the servers is expecting that the Client will...

It's dual purpose...it's for IDS and Network Operations troubleshooting. We use the Cisco 3 layer topo......access, distribution, core and these are our distribution switches. I like the sound of this...need to refresh myself on rspans but this sounds promising. Thanks much for...

How do you folks capture data for application analysis and troubleshooting - "monitors session" or VACLs??..(inline taps seems to be the best way but that can get very expensive). Please correct me if I make any inaccurate statements. Scenario: Two Cisco 6909s in HA mode - we want to be able...

No, I'm being told that's another product. I'm referring to the ACE load balancing module.

Does anyone know of a way to increase the session timeouts to the real servers?? We're new to ACE and just getting it deployed in various areas of our network. We have user's getting disconnected from their apps and at first we thought it had to do with Sticky sessions. Now I don't think so...

No ACE users?!... Those modules scare me...I was hoping to get some feedback.

All, I'm quickly becoming a fan of Cisco but not so much the ACE module. Configs are complex, look hard to troubleshoot, and there seem to be some potential gotchas. I've dabbled in Cisco for a little while but have been primarily a Nortel Passport/Alteon person..(until recently when we started...

Vince, I might give that a shot but I'll have to wait for a maintenance window...(Sat night/Sun morning). Thanks for the suggestion! Dane

Anthony, Good suggestion....thanks for the response. Any comment on whether 85% is critical, scary, getting scary, etc.?? Dane

Sorry so slow...out of a couple of days. I was seeing spikes that hit 85%. I don't ever remember seeing it that high before but it's not something I remember checking a lot. I've seen it maxed out when it was having problems on older version of code but once that was fixed I seem to remember it...

Question... I've noticed lost pings to VRRP interfaces lately and I don't ever remember having that problem. I've seen some issues pinging management interfaces and I know the switch places ping in a low priority queue..but this seems different. They're not just long responses (I extended...

Nevermind!...I found a CSB on the problem.

On the Nortel BCN routers, I know there were issues with those cards (dual 100 base-T cards). You could only run one of the two ports @ 100MB Full duplex...the other port had to be set to 100 Half duplex. I know you CAN set them both for full, I just don't remember what problems arise when you...

I assume by "network" you mean - physical connection, and not just the inability to get to some resource. If that's the case, it's most likely your server since a reboot/restart fixes the problem. If it were a flaky switch port or a bad cable, that wouldn't normally fix anything (although...

All, I'm interested in peoples experiences with respect to SSL decode using Sniffer products or Wireshark (or anything else you might be using). We have Infinistream Sniffer's where I work. Decoding SSL is done through the use of *unsupported* software they offer on their web site called...

*at home for a brief break* Andy - I think Cisco suggested that and it caused the problem to get worse. Other devices started losing adjacencies as well..(I'll verify to make sure though). I haven't even looked at any traces or anything....it's been madness and mayhem for the last 24+ hours...

I'll have to report back on that. I know it's been going on for a long time (meaning - it started with old code).....and I know the routers we just put in are more recent code. I'm mainly wondering if it's a huge issue between Nortel and Cisco that someone might be aware of. Otherwise I'll have...

We've had issues with our Contivity 5000...and at least one of our BCNs. I'll have to check to see if we're losing adjacency with our 8600. Thanks for the response...I'm working an Internet problem..but I'll check back once things settle a bit. Dane
