Windows file sharing over local network (SMB/CIFS) alternatives??

Windows file sharing over local network (SMB/CIFS) alternatives??

I want to share folders/files over local network and I'm looking for free alternatives to windows build-in functionality.

Windows build-in network sharing performs great but setup can be kinda cumbersome sometimes so I'm looking for a simpler solution.

I found some alternatives but I haven't used any yet.

Here is the list:

  1. D-LAN (https://www.d-lan.net/)
  2. nitroshare (https://nitroshare.net/)
  3. LAN-Share (https://github.com/abdularis/LAN-Share)
  4. filedropme (http://www.filedropme.com/)

Does any of them worth especially in terms of performance and usability? Do you have any better recommendations? What's your opinions?

What is the disadvantage of using a protocol design in which UDP and IPv4 are merged?

This being an address of 48 bits that includes a 32 bit IPv4 address and a 16 bit port number?



Basic VOIP QoS questions

I'm reading about QoS and dscp values and I'm tying to understand how this all works. I understand (I think) the existence of the TOS field and that there are several different combinations of class/drop probability values and Expedited Forwarding which I believe is a separate type of classification from the Assured Forwarded values.

I also understand that you can create class-maps to match packets with certain dscp values and then policy-maps to choose what to do with them (please correct me if I'm wrong).

My main question is how to packets get these values in the first place? I've done some packet captures, specifically made a test IP call (using the RingCentral software phone) and all of the call packets just had a 0 default dscp value. Is this something that would have to be set in the VOIP software somewhere?



How do I home lab voip/CUCM/UCCE/Collaboration etc?

Any recommendations on how to gain hands on experience in this technology?



Is using a hotspot for internet access feasible for an office with 10 employees?

We are forced to rent office space from a political campaign contributor and the internet access there is terrible. It's 5mb that goes back to a state firewall 90 miles away and is very unreliable. We are not allowed to get our own ISP into the building. There's no option to rent from anywhere else for at least a year and a half.

Right now a few key users have AT&T hotspots so that got me thinking maybe I could put a small firewall in place and have it use a hotspot as the WAN and then hook the LAN ports up to wireless access points.

How crazy is that idea?



I have a few quick questions about this DNS related PCAP that I'm looking at. Screenshot in comments.

https://imgur.com/fz3TWdr

x.x.224.16 is a client machine.

x.x.70.4 is a DNS server.

  1. x.x.70.4 is replying to the client with "Server Failure". Can we tell from the screenshot alone that the problem is on x.x.70.4? Or could the problem still lie on an upstream server that x.x.70.4 forwards the request to? (I don't know the OS of the DNS server)

  2. Why is the client sending an ICMP here? It's a Linux machine but I'm not sure what flavor at this time.

  3. [SOLVED: dns.id == 0xc43b] How can I filter on the Standard query/response hex code?

note: I only have the client side of the capture and do not have access to capture on the DNS side.

Any other advice or input would also be appreciated. Thank you.

edit: I'm completely new to troubleshooting DNS and UDP.

Hotel VOIP recommendations

I’m going to do my first VoIP installation in a small independent hotel. I have experience in setting up small business.

I looked into Fanvil since they have a hotel line but read that not a lot of people recommended it. Vtech also has a hotel line and will look into it.

The hotel doesn’t requiere any special features such as connecting the PBX to their PMS, they just want to use a in hotel in room phone (has room service, front desk.... buttons)

Do any of you have any recommendations hotel VoIP system and which phones to use?



Is infosec overrated?

This might not be the best forum to post this question in but since its mainly networking guys in here I'll put it across from more of a networking POV. Infosec guys are overrated, I've worked 2 companies with them in (both really nice guys) but as far as "contributing" or "knowledge" goes, there's nothing a infosec person does that a networking guy couldn't do either. They're glorified buzzword people that write essays and pass them to the higher ups who haven't got a proper grasp on things as well but see all the buzzwords and worries in the essays handed to them and then it either goes to networks or infrastructure for those guys to actually DO IT! Majority of the time this has happened with me i have replied with..."Already done 10 months back" I remember one time I got a 2 page list of questions from infosec about the network and over 70% of it I'd say didn't even make sense. They love a buzzword as I say, "we need to protect from DDoS attacks", so i sometimes reply with, "okay, how do we do that?". To which they have come back with responses like "better encryption", "better firewall rules", to which i raise my eyebrows and think..."you get paid to say things like that?" I sometimes as how and what does that mean then?, with no actual response there. I usually just reply with things like, we control the per client embryonic connections for incoming connections and our content filter and database is regularly updated and configured. To which they nod their heads and walk off. I swear they remind me of those in school or university were they join your group for a project, do 5% of the work and get the A grade at the end haha. It turned into a bit of a rant in the end but I wondered what other peoples thoughts were on the topic to?
