why didn't I find your channel a year ago?! I work at a service desk, as first line agent, had zero training, for a good half year my days were mostly spent panicking and crying in the bathroom... thank you so much for uploading these videos. 😍😘 now this whole work thing started to make sense and I feel less and less like a traines monkey🐒 pressing certain buttons because I was told to do that. 😁 this series should have been our official training.

Are the ones in green only able to be used on the kind of connection, or is it an example?

@thepun3721 4 года назад

example, notice his use of the word common, u can configure to wherever u want if you know what port gets sent where, u also run into two files going into the same port at the same time itll cause a problem

If FTP is not encrypted (unlike SFTP), then is the authentication sent in clear text? Isn't that a major security concern and thus, should not be used in production systems?

@tylerapple4431 4 года назад

For anyone reading, I have a question. I was under the impression that TCP used ports 1-1,023, but at 10:27 it was noted that VoIP uses TCP/5060 and TCP/5061. Does TCP extend past 1,023 and the ports up to 1,023 are just the more common ports? If not, can someone explain this to me? Thank you in advance!

@professormesser 4 года назад

Although ports 0 through 1023 are commonly designated as "well-known" ports, a service can actually use any available port from 0 through 65535.

@raymundoo2879 3 года назад

I think you confuses tcp/ip model. So the entire tcp/up ports from that range and more, txp doesn't have a specific port number

@nilbog2021 5 лет назад

I thought SIP used UDP? Other Network+ materials I've been watching have said it's UDP and I've also read this on the internet. Can you confirm that the test in fact says that SIP most commonly uses TCP?

@professormesser 5 лет назад

Although SIP can technically be supported over both UDP and TCP, it's not very common to find an implementation that uses UDP. Signaling protocols like H.323 and SIP use TCP.

@nilbog2021 5 лет назад

Ok great, thanks for the reply!

@Simonius95 5 лет назад

The question came up cause @ProfessorMesser used the VoIP example in the beginning (previous video) with UDP.

@esoterrestrial9627 4 года назад

Is it normal when starting this journey, to feel like none of this is ever going to make sense?! PM Makes it easy to stay engaged, but I fear none of this will stick, or is this just the pre-IT cert jitters?

@susiemartinez8983 4 года назад

I think it's pre-certification jitters. I'm not sure if you have experience working in the field but this information does become valuable once you start troubleshooting systems and networks. Not all of it is used and some stuff can be easily forgotten for this matter but it makes sense once you start working in the field. I always keep a A+, Net+, and Sec+ book handy for me and my colleagues as I know we are not all robots who remember everything from the top of our head.

@christopherr.690 4 года назад

The key is persistence. If something doesn't make sense take it slow or get info from additional resources, but don't give up. After some time it will all make sense.

@Stevedoug17 5 лет назад

Hi professor. Great video. Question though - with SNMP v3, if the data is encrypted, does this mean that it’s possible (or advisable) to send encrypted data over UDP? I thought UDP was less secure than TCP. Or perhaps it’s not necessarily less “secure” but rather less “reliable”. Just because the connection between A and B isn’t formally established doesn’t mean the data itself can’t be encrypted.

@raysaul 5 лет назад

I think you are confusing the secure and reliable here. Let me put it this way, TCP will have an active connection between server and client and both will acknowledge the data transfer between both of them. If 1 packet is missing the other side of the connection will tell the other part that it is missing that packet. On the contrary, UDP is connection-less one part will send data and will not care if you receive it or not it will continue to send all the data. Obviously you would like to use TCP (connection-oriented) to handle any encrypted data as both side will acknowledge that data transfer will be process and if any packet is lost it will be resend

@Stevedoug17 5 лет назад

@@raysaul Thanks for the reply. Yes, I was confusing the two. TCP/ UDP are layer 4 and encryption is layer 6. Encryption is independent from the transport layer but like you said, TCP would be preferred.

@shivex 5 лет назад

@@UndertakerU2ber Gaming over a network always uses UDP for the reasons you just mentioned. Same goes for a live stream from Twitch or RU-vid, you risk some lost packets but mostly a smooth experience. For example, in a shooter game a packet contains your location in the game, when 3 packets are sent for the 3 steps you took, if the 2nd packet drops it basically fixes itself with the 3rd packet arriving in quick succession, within miliseconds.
