I would like to know if it's possible to add a new drive to a raid5 set with the purpose to expand the storage available in the set. 9550 controller
For example to go from: 4x1TB drives to 5x1TB drives and do a resizefs on my linux partion and have it encorporate the empty space to the partition.
I moved a site that used to be at example.com/en/ to just example.com.
however the graphics as still linked to /en/.
What do I need to add to my .htaccess to make the site serve files under /en/ as well.
I did an upgrade of my Ubuntu Bionic server and certbot fails now with:
certbot
An unexpected error occurred:
ContextualVersionConflict: (cryptography 2.1.4 (/usr/lib/python2.7/dist-packages), Requirement.parse('cryptography>=2.3'), set(['PyOpenSSL']))
I can't seem to fix it no matter what I do.
I have a server with 4 250GB sata drives on regular sata controllers. I would like to setup Docker on some sort of fault tolerant file system so that if one of the drives fails the whole thing doesn't collapse.
I'm pretty sure it's probably not possible to format all fours drive as ZFS and have them as your boot drive as well for the OS. And ZFS is not recommended by the Docker WIKI anyways: https://docs.docker.com/storage/storagedriver/zfs-driver/
Maybe there is another fault-tolerant file system that Docker is compatible with?
Any ideas as to what is recommended in this case?
I have a router with two WAN connections from different ISPs. When I query 8.8.8.8 for a domain from ISP-A I get a completely different reply, from when I query 8.8.8.8 for the same domain from ISP-B.
I am beginning to think that one of them is rerouting the traffic from 8.8.8.8 and 8.8.4.4 to their own DNS servers to avoid carrying that bandwidth on their main pipes. So changes made to the IP of a domain would not show up as quickly on the one that is re-routing the traffic I suppose.
If the ISP won't do anything about it, is there anyone to complain to like maybe ICANN or LACNIC or ARIN? Who regulates ISPs? How would I go about gathering evidence? DIG screen captures?
If the URL ends in .HTML I have no problem controlling it and redirecting it within Joomla. But if ends in .PHP I get the 404 page.
I assume it can be fix one of two ways: 1. Give Joomla control of URLs ending in PHP so that I can redirect the URL from within Joomla or 2. Try to do it within the NGINX config:
location / {
try_files $uri $uri/ /index.php?$args;
}
location /oldsignup.php {
rewrite ^/.* http://example.com/signup.html permanent;
}
location /oldsignup2.php {
rewrite ^/.* http://example.com/signup.html permanent;
}
I tried the above but it failed.
One of the cloud instances I manage got hacked. It is powered down at the moment, but I want to bring it up disconnected from the internet. So I can examine and analyze it with it continuing to do it's harm.
What do I need to do to make that happen?
I have a webserver that has almost 4mbps of sustained traffic on the localhost interface. How can I tell what is causing that?
Basically I would like to do a 'ls -l' recursively showing only those directories named web. How would I accomplish that?
I always have to disable my .htaccess to be able to see my stats page located unrder my domain in /stats . What can I do to tell htaccess to ignore routing /stats?

If I start off with a 2 drive stripped ZFS POOL will it automatically become a fault tolerant POOLS like RAID-5 when I add the third drive?
I can't seem to find anything in the ZFS CheatSheets I find online about adding a third drive to a stripe set and changing to RAIDZ1.
Does anyone have any practical experience with such a scenario?
I initially created vmbr1 and did not assign it an IP. Used it as a bridge for container that had the public IP assigned to it. It did not work. I don't understand what else needs to be done.

My fail2ban bantime does not appear to be working. I still get repeated ban notifications from the same IP within 45 minutes of each other. My bantime is set to 24 hours.

I added 200 hundred iptable rules like these:
iptables -A INPUT -s 108.62.150.0/24 -j DROP
iptables -A INPUT -s 109.108.64.0/19 -j DROP
iptables -A INPUT -s 109.110.32.0/19 -j DROP
to block russian and eastern europe ips from my server.
However, my fail2ban is still going off for many of the ips which fall within those ranges.
The begining of my rule set looks like so:
Chain INPUT (policy DROP)
target prot opt source destination
DROP tcp -- 0.0.0.0/0 127.0.0.0/8
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED

DROP all -- 109.111.176.0/20 0.0.0.0/0
Why are they still getting through?
Is it the PUB_IN statements?? Should my block(DROP) rules appear before the PUB_IN rules?
