Don't know about a python cert, but there's a thread here about going to humblebundle and loading up on python books there.

I think that python expertise makes itself evident rather quickly, if given permission to turn on a Linux scripting host.
Yep. You just brought something relevant too for all "windows only" folks like me: a bit of Linux doesn't hurt. I remember there was a cert called LPI. Still relevant today?

well since 2016 is waning, I'll start the new thread.

probably going to go for that CISSP next.
maybe look into the AWS Solutions Architect
or maybe one of those Python Certs,

my eye are big again.... looking for that next fix...
I just became CCNA DC certified and also looking at the AWS associate certs and learning a bit more of Linux.

But Python cert? Is there one?

Hi

I decided to learn a bit of juniper. I have heard pf vMX and vSRX.

Are these good for the cert topics and maybe even higher than jncia?

Well seen Seittit, I didn't notice there was an attachment.

But if the capture was done as said between the clients and the VIP I wouldn't go for a problem in the appliance since this is the an ACK from the client to the server. Unless packets from server to client were filtered out.

Hard very hard...
I run a lot. 3 times a week I go running by the beach with a good playlist.

Getting into something new related to arts may also help. As a kid I used to play the piano so Im now getting back to it and guitar.

For "meditation" (thinking about nothing) I heard of painting "mandalas". I bought a book from amazon and fine tip pens. I can do that for hours.

Hi Lynk,
In my experience that happens when there are losses between the clients and the server. Do a long extended ping and check results (if server allows pings). Try differente packet sizes.

ping 8.8.8.8 -t -l (packet size in Bytes)

Yes, it may be because of duplex mismatch but its not the only cause. Among some may be:
- Bad cabling
- link saturation
- bad wireless signal/interference

You should do tests on various segments on the path from clients to servers (hopefully you have access to all)

A good software to test the path is WinMTR (www.winmtr.net) but as I said before devices in the path must allow pings through and replies (the ASA would probably be a problem)
