Apache Reverse Proxy from HTTPS with HSTS from specific port to specific port on HTTP
cn flag

If host some app on some port ie 3000 through docker but that app doesn't support HTTPS while my whole domain has SSL and HSTS enabled which doesn't allow me to even enter to that app (because HSTS redirects everything to HTTPS). I heard it is possible to access HTTP sites through HTTPS through Proxy Reserve but I've completely no idea how to set it up, I tried many times in many ways and everything fai ...

Debian unattended (preseed) installation, access to audio card(s)
tr flag

I'm using the preseeding feature in order to shape a custom Debian 10 x64 system. Everything is happening well, except that during the late_command step, I'm running a shell script to configure and deploy miscellaneous things and I would like to be able to access the physical audio interfaces.

Usually, I'm doing that using pacmd list-sinks and then I can easily access the different audio cards names. Bu ...

DNS Resolver and Request Port Filtering
gd flag

During DNS amplification attacks on a DNS server, I observed that some DNS requests have for couple IP/port something like 104.49.96.196:80. I understand this is spoofed IP, but is it ok to consider filtering the port of the DNS request? I believe we should not expect a port > 1023. Is it a safe assumption? In that case, I believe this is an easy win to spot and not reply to DNS amplification atta ...

Wireguard slow but only for windows upload
nl flag

We have the problem that the connection from multiple client networks via Wireguard Tunnel to a Samba share on a server is slow, but weirdly it only affects Windows 10 and only uploads.

A Linux Host can upload with up to 120MB/s while Windows can only upload with 10-50MB/s (it varies for the different networks we have). It's not limited to smb, I get the exact same test results with Iperf (udp an ...

How much free space does Windows really need to be performant?
in flag

We have a virtualized file server here whose data resides on a SAN - performance through the SAN is plentiful.
But now the 2TB disk on the virtualized Windows 2012R2 file server is almost full since several weeks (30GB Free) and we discuss internally how much free space Windows really needs to be performant.
For ages there has been a recommendation that NTFS needs about 10% free space - can this be measur ...

GRPC (HTTP2) with GCP instance

I am testing out both GRPC, which uses HTTP2, and the nanos unikernel. I have written a small test server in Golang that has an internal GRPC server that has requests made by a client connection in the same application. I set up TLS for the GRPC server and client and it works fine locally. It also runs properly locally as a container image using ops (which is a management tool for running nanos containe ...

Does isc-dhcp-server-ldap work with DHCPv6?
cn flag

I'm trying to add IPv6 to my network, which uses DHCPv4 with its data stored in an LDAP server. I'm using the Ubuntu module isc-dhcp-server-ldap v4.4.1 to configure the DHCPv4 server and I'm very pleased with it.

I would like to configure my DHCPv6 server the same way. I realise that DHCPv6 options differ from DHCPv4 options and that there is no direct translation from DHCPv4 to DHCPv6.

I would b ...

mdadm partitions gone after reboot

I had a RAID 6 setup in Cockpit UI with multiple partitions.

How to block dots "." in an iptables rule?
vn flag

I have this rule in my iptables to block domains ending with .watch:

sudo iptables -A OUTPUT -j DROP -m string --string ".watch" --algo kmp

But the problem is that the . cannot be matched. So the line above does not match anything. But if I remove the dot from .watch to watch it works okay.

How can I block the dots "." in iptables rules?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
