Telnet smtpserver 25

Telnet smtpserver 25

oya i am doing it, still in trying.... but why with thunderbird i cant send an email? dont have problem send it in web browser

telnet: connect to address 52.98.65.18: Operation timed out so this means port 25 is still blocked?

If it is in trying and not gave an answer right away then your port is blocked

icmp_types = "{ echoreq unreach }" table <bruteforce> persist set skip on lo0 scrub in all fragment reassemble max-mss 1440 block all pass in on wlan0 proto tcp to port 22 \ keep state (max-src-conn 15, max-src-conn-rate 3/1, overload <bruteforce> flush global) pass out proto { tcp udp } to port { 22 25 53 80 123 443 110 143 993 } pass out inet proto icmp icmp-type $icmp_types do i do it correctly ?

And when you say your browser I guess you are using a webmail

Completely different thing

Port blocked or your smtp server/ip is incorrect

And when you say your browser I guess you are using a webmail

yes, oo ic

Port blocked or your smtp server/ip is incorrect

i use smtp.office365.com for hotmail account

Ho

Maybe it refuses clear text port 25

And only takes ssl connections

Generally port 465

Or 993

Just googled, it says port 993

Wait no sorry smtp https://support.microsoft.com/fr-fr/office/param%C3%A8tres-pop-imap-et-smtp-pour-outlook-com-d088b986-291d-42b8-9564-9c414e2aa040

Totally different server it seems

smtp-mail.outlook.com:587

With starttls

Hmmm I see also this possibility smtp.office365.com Port: 587 Encryption method: TLS

Différents services in Microsoft products…

@Corocor0 how’s that?

smtp-mail.outlook.com:587

oke this one is working. Thx stéphane T 👍

Hanging out in the FreeBSD Foundation stand at Open Source 101 Online 2022

btw if we update the /usr/src do we need to rebuild buildworld and kernel? because last time I built my own kernel using custom kernel, but now idk it goes back to GENERIC.

if you do buildworld/buildkernel, you need to update /etc/make.conf's KERNCONF to point to your kernel.

if you do buildworld/buildkernel, you need to update /etc/make.conf's KERNCONF to point to your kernel.

I used make buildkernel KERNCONF=MYKERNEL then install MYKERNEL and it was working. But then yesterday just noticed it went back to GENERIC. Dont know what cause my custom kernel go back to GENERIC kernel.

do updating /usr/src with gitup -c release remove my custom kernel?

did you do freebsd-update?

did you do freebsd-update?

ya i did

that's why 🙂

freebsd-update and buildworld/installworld are incompatinle. You can rebuild your custom kernel and install it

*incompatible -- My typing sux this early :)(

freebsd-update and buildworld/installworld are incompatinle. You can rebuild your custom kernel and install it

so if i run freebsd-update should i rebuild and install also buildworld?

if you run freebsd-update, you just need to build/install your custom kernel.

freebsd-update brings the GENERIC kernel binaries

freebsd-update brings the GENERIC kernel binaries

😉 thanks

My absolute pleasure.

Hi friends sorry for someone who is new to learning this os (free bsd) what do you recommend?

Start by the official handbook over freebsd.org Then you can also read the book "Absolute FreeBSD" by Michael W. Lucas Also for curated tutorials/talks/guides check the channel we have for this group @FreeBSD

Thank you I really appreciate your help.

Also for a quick guide, you can take a look at the section I FreeBSD config page over https://unixworks.codeberg.page/

This operating system is still unknown to many people, especially in Iran Also, there are very few teachings about it in Persian . I am a civil engineering student but I have no interest in it . To be one level higher than other students, I want to start reading English books until one day in the security world I have something to say.

Of course, there are people who are aware but do not like to share their knowledge with others, except for a few perfect people.

Of course, I do not know about your country, but in my country, most students are interested in a field other than their own. Of course, I'm not in that category, and my case is a bit complicated

If you want to build and setup for desktop with freebsd you can read vermaden blog. I always go back to his blog when setup my workstation with freebsd. or you can go to forums.freebsd.org but freebsd handbook is good way to start. or you can try ghostBSD, its freebsd with DE installed.

82801 PCI Bridge (no driver attached) Any suggedtions? Its ich7 pci bridge

I guess it happens after cpu upgrade

Does the freebsd kernel have any big advantages over linux?

Just referring to the kernel, not the whole userspace

anyone know tools like naps2 (in windows/ linux) for freebsd?

Does the freebsd kernel have any big advantages over linux?

Idk if its kernel feature, but you can run linux software on freebsd. Its builtin. So its advantage is that it can run both of them

@Shifulor the syscall emulation is in the kernel linux.ko/linux_common.ko/linux64.ko, and the linux "userland" is in /compat/linux, and sourced from ports in the emulation category.

Ah, makes sense

Good morning, I have installed freebsd with zfs. I noticed that the RAM used is 87%. How can I fix it?

Did you set deduplication on?

Did you set deduplication on?

I do not know. how can i deactivate it?

If you enabled it and you disable it, you still have to move the data for it to change Do you use any GUI? How much ram does your computer have?

I don't use gui and my pc has 16gb of ram

Thats not good

Have you tried the free comman

Or top or any monitoring really

i use top and i noticed that zfs arc uses too much ram

Hi. Recently I moved from Linux to FBSD and wonder how can I stop port scanners in FBSD while I was doing this via psad package and iptables in linux Thanks

look at fail2ban and pf

or see if psad has been ported 🙂

@Kratos8383 you can set a sysctl to limit the ARC.

I limited the use of arc with sysctl but when i run the dmesg | grep warning comes out of this point WARNING: ignoring tunable zfs_arc_min (using 530728064 instead). How can fix it?

@Larry_Rosenman I limited the use of arc with sysctl but when i run the dmesg | grep warning comes out of this point WARNING: ignoring tunable zfs_arc_min (using 530728064 instead). How can fix it?

you want to set the _MAX sysctl

what were you trying to set it to ?

also, how much RAM do you have?

I set both vfs.zfs.arch_max and min to 1024 on sysctl. The warning message I wrote a little while ago came out.

that's WAY too low, hence why it whined.

The pc has 16gb of ram
