I appeal to your knowledge in search of the best ideas to answer the following two questions:
As a provider of VPS servers (servers to which I do not have access), what would be the best method to limit the number of emails of each customer? (KVM virtualization via Proxmox, public IP...
Although I use the official templates for CentOS / Debian and Ubuntu and in the cloud-init section of proxmox I manually configured the IPv4 and IPv6 addresses, only IPv4 is taken into account.
Any idea what I'm missing?
I own a hosting company and I often face the situation where my clients using weak passwords end up being broken and at the same time my VPSs become the source of scans on other hosting companies.
I managed to block through Suricata the situation in which a client scans a certain IP...
Does anyone have any idea if the maximum number of external connections to a certain port can be controlled from the proxmox Firewall or from Suricata, but without saying which port it is?
Automatically track external connections for each port in order to discover the scans coming from my...
I would like to receive some suggestions regarding best way of merging few physical servers located in different physical datacenters (under 4ms from one to another).
The idea will be to have one single private subnet which will make our life easier in case of a VM migration.
Last night we upgraded our proxmox using 6to7 script on a OVH Game server with Ryzen 3800X.
After ugrade without any kind of error we rebooted the node and then we were unable to access internet.
Fixed internet access by adding MAC address on /etc/network/interfaces with IPMI and when we...
I would like to know if exists such a solution to implement at host level any kind of software to detect users who are using our IPs for port scanning and brute forcing servers over the internet.
Unfortunately we're very close to lose our leased /24 subnet and we need such a solution...
Thank you. Opted to refund all NAT LXC containers which were unable to pay extra for dedicated IP address because it was too difficult to identify abuser and I was very close to lose my whole rented /24 subnet.
Best regards, Florin.
I try to split /64 subnet IPv6 from OVH into /112 subnets for my LXC containers.
My server has 2001:41d0:700:4354::/64 and I've set up this configuration:
iface vmbr0 inet6 static
I encounter an unpredictibile situation on my small business.
After selling over 100 NAT IPv4 VMs with 50 public ports each and /64 IPv6, I've started to receive abuse reports on NAT IPv4 which says that one of my customer scans random hosts for weak passwords and things like this...
For the first time I try to use IPv6 with Proxmox (I don't have experience with IPv6 at all).
My problem is related to fact I can ping ipv6.google.com from main node but I can't ping from LXC container. When I try to ping from container nothing happens, ping command freezes.
I run some LXC containers and I saw that load avg. on LXC container it's exactly same as node's itself.
Can anybody tell me how to fix this issue?
proxmox-ve: 6.4-1 (running kernel: 5.4.151-1-pve)
pve-manager: 6.4-13 (running version: 6.4-13/9f411e79)...
I come with an update.
On IPMI it reported an "ECC uncorrectable" and I started to manually check DIMM by DIMM but until now, everything is fine with 4/8 DIMMs.
I would like to ask, what else should I check if all DIMMs will be treated by Memtest86 as working normally?
Just those lines before freeze
