Hello,

I passed 4 days without fapping nor watching porn, but I still resist. Now, I want to share with you what I feel.

1-Although, I don't sleep enough these days, I feel like a new source of energy on me.

2-I sometimes think about or imagine some scenes that make me hot, but it seems that the frequency has decreased because I try to focus on some other projects. That happens generally when I relax.

3- From time to time, I try to fool myself and find a pretext to fap or to see porn, I start touching ... but as soon as I remember my commitment I stop and try to div on my task.

Regards.

Hello,

I noticed the some APT group's names are prefixed with TEMP, for instance : TEMP.Zargos, TEMP.Periscope, and TEMP.Reaper. Is it sort of ID ? please could you give more information ?

Kind regards.

It has become a standard naming convention for APTs that you cannot identify but because of the complexity or range of the attack you believe it is an APT.

So if you are writing up a report on an APT level attack and you cannot currently who it is, the people will use the TEMP. to indicate that. If they later discover the APT is know some places will go in and edit the report and change the name others will indicate near the top that the TEMP.* is know as some other name.

Then in those cases where it is a brand near APT they will drop TEMP. and name them with the rest. For example TEMP.reaper was discovered to be an APT which worked under a known APT but has now started working on their own, so places are calling them Reaper now.

Then in other cases you will have various companies use thier own name; which is why some APTs have a long list of names.

Thank you for you reply.

And is there an authority of naming? something like CVE.

None at all. You get the ones created by all the security companies, and ever so often the name used by different governments gets released so those get added to the list.

There is probably someone that is tracking the APT-## numbers but I don't know what that is.

Hello,

I'm 26 years old man and don't want to get married, I don't feel that someday I'll fall in love.

I think some fears are the real reasons behind this situation.

First of all, I work but I'm not very well paid, I don't want found a family and make it live under poor economical condition.

I fear being cheated by the partner that I choose. and I don't want to waste time with stupid problems that I have seen in many couple.

I fear having bad and evil children, that will destroy me with the get older.

In other words, except relationships on bed and some tenderness from wife ,I don't see the benefits of getting married.

I know that this is not normal, could you please help to get things clearer.

Regards.

I see, so the most important thing is to share similar values.

I'm young and married. Here is my 2 cents.

Plenty of people wouldn't ever cheat. Love is real and falling in love is possible for you, if you are open to it.

Children need loving homes not expensive toys. Don't assume you can't afford kids (or that your future spouse can't either).

The chances of you having an evil kid is extremely low. If you are a loving parent your kid is very unlikely to murder you or whatever else you are afriad of. Assuming you provide a loving and nurturing home, your kids will likely be completely normal and average.

Marriage is hard work. Being with someone for life is tough but it can be so worth it.

I say ditch the fears. Let go of expectations. Open yourself up to the possibility of falling in love and just see where life takes you.

Hello everyone

I'm 26 old, a single man, a network engineer and I have a job. I think I'm useful for my company even if the stuff I work with doesn't show gratitude.

I fixed some objectives that need a lot of work : getting some certifications in-order to work for more important companies. I reached some of them, and I'm in the way for the others.

The problem is that I often feel very bored, tired "even in the morning".

I don't have any friends just colleagues.

I think the main reasons for that I have read some books like the prince of michiavelli, the 48 laws power of robert greene and how to think clearly of Rolf Dobelli. Combine this with my experience in the military service (~1 year). Those factors made me convinced by the idea that everyone is selfish, and that every initiative from other people to become my friend, is the first step of a plan to server their own interests.

I try persuade to not get married in the future, I'm not engaged in a relationship yet, because that will impose a responsibility a bigger than me, Also, I don't think enough patience for a woman or even a child. Perhaps I'm arrogant but I know that I lie to my self about marriage and the real reason for this problem is my worries of being betrayed.

The feel the word "love" very heavy for my tongue, I can't say it to anyone expect my youngest brother and my mother.

Regards.

Hello,

Sending configuration information like DNS server, in case of Stateless and Stateful DHCPv6, is clear for me. I have to define those information inside ip dhcp pool XYZ.

Now, I have a problem with SLAAC. I only know that I have to enable unicast-routing and to set M and O flags to 0. But in all the documentation I have checked, I didn't find where to include all the additional information like DNS, default gateway ...

Regards;

2
9 comments

The link provided by /u/madmike78 is correct.
SLAAC = Stateless DHCPv6
Take a look below to understand from where the host receives the addressing information when using Stateful vs Stateless.

Stateful DHCPv6

  • IPv6 address: DHCPv6
  • Prefix length: DHCPv6
  • DNS: DHCPv6
  • Default gateway: NDP (RS,RA)

Stateless DHCPv6 (SLAAC)

  • IPv6 address: Prefix from NDP (RS,RA) , host-id from EUI-64 or random
  • Prefix length: NDP (RS,RA)
  • DNS: DHCPv6
  • Default gateway: NDP (RS,RA)
see more
Original Poster2 points · 7 months ago

Thank you for the reply.

I think there is difference between SLAAC and Stateless DHCPv6. When you set M and O to zero. How can a client know the DNS server ?

Using different combinations of the M and O flags, RA messages have one of three addressing options for the IPv6 device:

  • SLAAC (Router Advertisement only)

  • Stateless DHCPv6 (Router Advertisement and DHCPv6)

  • Stateful DHCPv6 (DHCPv6 only)

In the case of Stateless DHCP, you can do it by :

ipv6 dhcp pool poolname

dns-server ipv6-address

interface type number

ipv6 dhcp server poolname [rapid-commit] [preference value] [allow-hint]

ipv6 nd other-config flag

Regards;

2 points · 7 months ago · edited 7 months ago

Hmm, i might have confused you a bit.

SLAAC

  • IPv6 address: Prefix from NDP (RS,RA) , host-id from EUI-64 or random
  • Prefix length: NDP (RS,RA)
  • Default gateway: NDP (RS,RA)

Stateless DHCPv6

  • DNS: DHCPv6

With pure SLAAC the host has no way to get DNS information so in most cases DHCPv6 is used to provide DNS so "SLAAC + DNS from DHCPv6 = Stateless DHCPv6".

Stateful DHCPv6 uses both M-bit and O-bit.
SLAAC uses only the O-bit.
However if you only enable the M-bit on the router it understand your doing Stateful so it also enables the O-bit.

see more
Original Poster2 points · 7 months ago

Thank you for the explanation. That's what I wanted to hear, SLAAC alone can't do all the job.

Note: According to the course, Stateful DHCPv6 doesn't need O-bit.

The M flag indicates whether or not to use stateful DHCPv6. The O flag is not involved.

Hello

My actual laptop has only 4 Go, with i5-2450M ( with 2 cores) processor.

The OS and Firefox consume about 3 GB of RAM, and as you can imagine there is no place for VMs.

I wanna buy a new laptop to do some practical penetration tests. I guess that I'll need in average 2 or 3 virtual machines running in the same time. 1 for kali, 1 for windows client (xp|7|8|9|10) and one for windows server (20{08|12|16}).

Because, My economical situation :( I want to estimate the minimal physical characteristics, and I need some assistance:

1 - Do you think that 2~3 machines will be enough for the majority of simulations ?

If the answer is YES! , are the following estimations right ?

2- At least 16 GB (4 for the physical machine, between 2 and 4 for each VM)

3- At least 512 GB disk space.

4- I don't really know if an i5 or i7 6th or 7th (with 2 cores/4 thread) generation will support the load.

Regards.

exactly my situation right now, running a think-pad with 4 gigs of stock ram. I recently switched from Ubuntu to Xubuntu (ubuntu on xfce) and removed everything that I do not use.

Currently, 2 tabs in Firefox + Spotify streaming uses about 1.2 gigs of ram and I am able to use a single VM and a second one without GUI.

I am planning to upgrade to 16 gigs of ram soon and would suggest you to do the same. ( but them current ram prices. )

Hello,

I plan to use a new computer for virtualization with virtulbox, or KVM.

I found many processor in the market have with 2c/4t, 4c/4t and 4c/8t.

In average, I will use 2~3 virtual machines at the same time.

In my case, If I give 1 thread, 2 thread or 1 core for each VM, Does it make a great difference in performance ?

In other words, If I use 2c/4t with 1 thread for each VM, or 4c/4t with 1 core for each VM. Will I see a big difference ?

Note: VMs will run Application of general use : MS office, browsers etc...

Hi,

I got confused after reading about an experience in "Fluent Forever", Chapter 2 ~ section : TIMING IS EVERYTHING: THE END OF FORGETTING , by Gabriel Wyner.

In this experience, There was a space of 6 months between the study session and the exam. Only one session of recall was permitted.

The objective was to see which time is the more suitable time to do recall session.

The result can be seen here

Now, I don't understand why the 4th week session was more efficient than the 12th and the 24th week sessions ?

I see a contradiction with the forgetting curve, which shows a correlation between time and memories for a period of time, then the memory curve becomes steady.

What do you think about it ? do you have a logical explanation ?

Thank you;

Hello,

I'm now in the last chapter in CCNA 2, which about CDP and LLDP.

In one activity that aim to compare between CDP and LLDP, the following characteristic was proposed :

Advertisements share information about the type of device that is discovered, the names of the devices, and the number and type of interfaces.

The right answer was CDP "ONLY".

I don't believe that this characteristic differentiate CDP from LLDP. LLDP shares the same kind of information, right ? what do you think ?

Hi

I'm studying ACLs in CCNA routing and witching essentials

In one activity, I was asked if router will deny or allow the following address 10.10.10.50.

The rule was :

access-list 18 permit 10.10.10.0 0.0.0.63

I selected permit, but correction shows my answer as wrong. as you can see here

I'm confused. I think that the router will compare between 10.10.10.[00******]. which matches with 10.10.10.53.

What do you think ?

Hello;

I want to ask if the port titled PoE (Power Over Ethernet) in the picture of Cisco router 1921, is it used for supplying with or for receiving power ?

After reading the router's Data-sheet, I believe that the RJ-45 can only be used to supply PoE, they can't be used to empower the router, is that right ?

https://image.jimcdn.com/app/cms/image/transf/none/path/s31abad0af066c91a/image/i21ece827458fa8fb/version/1427358181/image.jpg

Thank you;

The PoE power port on the 1921 is used to supply additional power to the router so that it may supply PoE via its own network interfaces.

For example, if I want to power a phone or an access point via the 1921 interfaces, I would need to plug an additional power supply into the PoE interface labeled in the diagram you linked. Once that is done and the power supply is powered on, then PoE devices can plug into the router's interfaces and be powered successfully.

Thank you very much for the explanation you provided to me.

So, without this additional PoE supply shown in the picture, the router can't empower other devices through PoE ?
