I have installed the newest iRedMail server. It comes with autodiscover solutions for Thunderbird and Outlook. However out clients with Macs still can't autoconfigure their OSX Mail or IOS Mail.
Is there any way to set up autodiscover for OSX Mail and IOS Mail in iRedMail server?
I have Proxmox 5.2 server in OVH. I have few LXC containers and everything work just fine except when I add a second IP to the container it doesn't work - inside in the container the interface exists and I can ping it from inside. On the other hand from outside it's unreachable. I checked few of the IP's and everyone of them work perfectly well if alone in the container. The MAC addresses are OVH type.
Ah, and it was working in Proxmox 4.2 before I upgraded it to Proxmox 5... Of course I was trying this with old containers and also with freshly made ones - no difference.
Any idea what's wrong?
On ny Ubuntu 14 box I have weird activity looking like attack on Wordpress page. Apache log shows a lot's of this:
191.96.249.54 - - [25/May/2016:00:46:57 +0200] "POST /xmlrpc.php HTTP/1.0" 500 585 "-" "Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)"
191.96.249.53 - - [25/May/2016:00:46:58 +0200] "POST /xmlrpc.php HTTP/1.0" 500 585 "-" "Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)"
191.96.249.54 - - [25/May/2016:00:46:59 +0200] "POST /xmlrpc.php HTTP/1.0" 500 585 "-" "Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)"
191.96.249.53 - - [25/May/2016:00:47:00 +0200] "POST /xmlrpc.php HTTP/1.0" 500 585 "-" "Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)"
It look exactly like the situation described here: http://blog.carlesmateo.com/2014/08/30/stopping-and-investigating-a-wordpress-xmlrpc-php-attack/
The first thing which cane to my mind was to block those guys with iptables so I put:
iptables -A INPUT -s 191.96.249.54 -j DROP
iptables -A INPUT -s 191.96.249.53 -j DROP
But it kept going.
Because I use UFW I added UFW rules:
ufw deny from 191.96.249.54 to any
ufw deny from 191.96.249.53 to any
But nothing improved. Then I disabled UFW and it stopped!
Mu UFW rules are (ufw status):
Status: active
To Action From
-- ------ ----
80 ALLOW Anywhere
443 ALLOW Anywhere
143 ALLOW Anywhere
993 ALLOW Anywhere
25/tcp ALLOW Anywhere
465/tcp ALLOW Anywhere
Anywhere DENY 191.96.249.54
Anywhere DENY 191.96.249.53
80 (v6) ALLOW Anywhere (v6)
443 (v6) ALLOW Anywhere (v6)
143 (v6) ALLOW Anywhere (v6)
993 (v6) ALLOW Anywhere (v6)
25/tcp (v6) ALLOW Anywhere (v6)
465/tcp (v6) ALLOW Anywhere (v6)
Then I realized that the very first rule is to allow http... So I deleted it and added it again so now it's at the end of the chain. It helped. Apparently I should insert the blocking rule like this:
ufw insert [position] [theRule]
Am I right? Well apparently it worked, but is it good practice or should I do it other way?
I know this question was asked here and there but no answer works for me. After hours of googling I can't figure it out. I have Ubuntu 14 server and I need to make few virtual servers - I want something like VPS in DigitalOcean - Virtual machines with external IP.
So I have an Ubuntu server with couple IPs but only one physical network card.
The host system must be accessible only by the main address 198.201.29.211.
Of course virtual machines should behave like normal physical servers and be also able to connect to host server.
This is my /etc/networking/interfaces file:
# Loopback device:
auto lo
iface lo inet loopback
iface lo inet6 loopback
# device: eth0
auto eth0
iface eth0 inet static
address 198.201.29.211
netmask 255.255.255.192
gateway 198.201.29.193
# default route to access subnet
up route add -net 198.201.29.192 netmask 255.255.255.192 gw 198.201.29.193 eth0
auto eth0:0
iface eth0:0 inet static
address 198.201.29.247
netmask 255.255.255.192
auto eth0:1
iface eth0:0 inet static
address 198.201.29.248
netmask 255.255.255.192
auto eth0:2
iface eth0:0 inet static
address 198.201.29.249
netmask 255.255.255.192
Every IP (except the main one: 198.201.29.211 on eth0) should be exclusively attached to appropriate virtual machine (inside on eth0).
My company have Fujifilm ASK 2000 photo printer. I can't find any drivers for Linux.
Maybe anybody know is it possible to use it with Linux? Maybe the printer uses some standard printer language like PCL or PostScript?
Linux Distribution is Ubuntu 14.04.
