I have database mirror set up in one of my servers and all seems to be fine, however, from time to time I get this error message in the logs:
--Execute it on Primary/Secondary server EXEC xp_readerrorlog 0,1,"Error",Null, NULL, NULL, N'desc'
Database mirroring connection error 2 ‘Connection attempt failed with error: ‘10060 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)’.’ for ‘TCP://MIRROR_SERVER_DB01:5022’.
--============================================================================== -- query that shows the current state of each database in the mirroring --============================================================================== SELECT db_name(sd.[database_id]) AS [Database Name] ,sd.mirroring_state AS [Mirror State] ,sd.mirroring_state_desc AS [Mirror State] ,sd.mirroring_partner_name AS [Partner Name] ,sd.mirroring_role_desc AS [Mirror Role] ,sd.mirroring_safety_level_desc AS [Safety Level] ,sd.mirroring_witness_name AS [Witness] ,sd.mirroring_connection_timeout AS [Timeout(sec)] FROM sys.database_mirroring AS sd WHERE mirroring_guid IS NOT null ORDER BY [Database Name];
as it happens only sometimes, and I could not identify what else running at the same time – could have triggered this error,
what are possible things to look at while troubleshooting?
this server is hosted in the USA and I am not admin on the machine, only
sysdba in the sql server world.
I’ve managed to create a obfuscated shellcode that is compatible with windows/meterpreter/reverse_tcp and windows/shell/reverse_tcp (metasploit) payload’s handlers. When testing with metasploit listening with windows/shell/reverse_tcp payload the connection is not detected, when I test with metasploit listening with windows/meterpreter/reverse_tcp set the behavior is detected. The detection seems to post connection..
Is there additional options/variables I can set in the windows/meterpreter/reverse_tcp payload handler to evade antivirus (windows defender) detecting meterpreter behavior?
I’m looking to evade detection server side (metasploit listener options), not client side I’ve done that.
Before asking this question I got through a lot of posts for finding a simple explanation about:
- How an HTTPS/SSL connection establishes?
but I could not find a good one, in addition here, i can ask more question until it becomes clear for me, it may also be helpful for many others. And also there is another question Related to this topic:
- How the client generates the privet key?
How can someone prevent an eavesdropping in a powerline connection? Is the AES-128 encryption that is used capable of securing a powerline connection?
When we connect to postgreSQL via ssl-mode=verify-full how will I make sure if the certificate I passed is used while making the connection?
With ssl_is_used(); shows only true or false. Is there any other extension or pg_catalog views that shows the root cert used in making connection to the DB ?
I just bypassed SSL pinning on an android application but the problem is application won’t let me play with the request on my intercepting proxy. It says something like problem with your network or check your internet connection, it might be slow. It used to say the same thing before I didn’t bypassed SSL pinning.
My assumption is that the application is coded in such a way that it expects to get response from the server quickly. Since am playing around with the request on my intercepting proxy there is no response from the server because the request is still on my proxy and not sent to the server.
Is there any way out of it?
iam trying to recover innodb table which has 1.5M rows from ibd file ( 5.5 GB )
this is the exact steps i do:

create the table
Alter Table discard tablespace

is there any way to import it ??
I’m preparing to run Curse of Strahd, and one of my players wants to play as a Shadar-kai who is loyal to the Raven Queen.
In the adventure’s set up, it says (p. 9):
For obvious reasons, I’d like to know more about the connection between these Dark Powers of the Shadowfell and Strahd.
I’ve looked at the related question What are the "Dark Powers"? but it seems to be an old question based on old D&D lore (from 2e and 3e) that doesn’t help in this regard, because the Shadowfell appears to have been introduced in 4e (and remains in 5e). Hence this question about the 5e adventure Curse of Strahd and the 4e/5e Shadowfell is not a duplicate of that question.
Rather than focusing on the Dark Powers (since that would make this a duplicate), I want to instead better understand the relationship between Strahd, Barovia and the Shadowfell, especially if the Raven Queen is supposed to be in any way related to any of this. If it turns out that she is related to this, then this player’s backstory will have to include why the Raven Queen is sending their PC to ruin Strahd’s day (especially since, AFAIK, the Raven Queen dislikes sentient undead), whereas otherwise the “Raven Queen dislikes sentient undead” thing is probably enough on its own.
So, in what way is the Shadowfell related to Strahd, and the plane of Barovia (if at all)?
I’m chiefly interested in any 5e lore that might help me understand the connections between the Shadowfell and Barovia/Strahd, but 4e lore is acceptable as well. 3e and older lore I won’t shun if it can help in any way, but the fact that the Shadowfell didn’t exist back then implies that answers must contain at least some 4e/5e lore as well for such answers to be helpful.
