My school just tried to hinder my revision for finals now. They've denied me access just today of SSHing into my home computer. Vim & a filesystem is soo much better than pen and paper.

So I went up to the sysadmin about this. His response: "We're not allowing it any more". That's it - no reason. Now let's just hope that the sysadmin was dumb enough to only block port 22, not my IP address, so I can just pick another port to expose at home. To be honest, I was surprised that he even knew what SSH was. I mean, sure, they're hired as sysadmins, so they should probably know that stuff, but the sysadmins in my school are fucking brain dead.

For one, they used to block Google, and every other HTTPS site on their WiFi network because of an invalid certificate. Now it's even more difficult to access google as you need to know the proxy settings.

They switched over to forcing me to remote desktop to access my files at home, instead of the old, faster, better shared web folder (Windows server 2012 please help).

But the worst of it includes apparently having no password on their SQL server, STORING FUCKING PASSWORDS IN PLAIN TEXT allowing someone to hijack my session, and just leaving a file unprotected with a shit load of people's names, parents, and home addresses. That's some super sketchy illegal shit.

So if you sysadmins happen to be reading this on devRant, INSTEAD OF WASTING YOUR FUCKING TIME BLOCKING MORE WEBSITES THAN THEIR ARE LIVING HUMANS, HOW ABOUT TRY UPPING YOUR SECURITY, PASSWORDS LIKE "", "", and "gryph0n" ARE SHIT - MAKE IT BETTER SO US STUDENTS CAN ACTUALLY BROWSE MORE FREELY - I THINK I WANT TO PASS, NOT HAVE EVERY OTHER THING BLOCKED.

Thankfully I'm leaving this school in 3 weeks after my last exam. Sure, I could stay on with this "highly reputable" school, but I don't want to be fucking lied to about computer studies, I don't want to have to workaround your shitty methods of blocking. As far as I can tell, half of the reputation is from cheating. The students and sysadmins shouldn't have to have an arms race between circumventing restrictions and blocking those circumventions. Just make your shit work for once.

**On second thought, actually keep it like that. Most of the people I see in the school are c***s anyway - they deserve to have half of everything they try to do censored. I won't be around to care soon.**

Often I hear that one should block spam email based on content match rather than IP match. Sometimes even that blocking Chinese ranges in particular is prejudiced and racist. Allow me to debunk that after I've been looking at traffic on port 25 with tcpdump for several weeks now, and got rid of most of my incoming spam too.

There are these spamhausen that communicate with my mail server as much as every minute.
- biz-smtp.com
- mailing-expert.com
- smtp-shop.com

All of them are Chinese. They make up - rough guess - around 90% of the traffic that hits my edge nodes, if not more.

The network ranges I've blocked are apparently as follows:
- 193.106.175.0/24 (Russia)
- 49.64.0.0/11 (China)
- 181.39.88.172 (Ecuador)
- 188.130.160.216 (Russia)
- 106.75.144.0/20 (China)
- 183.227.0.0/16 (China)
- 106.75.32.0/19 (China)
.. apparently I blocked that one twice, heh
- 116.16.0.0/12 (China)
- 123.58.160.0/19 (China)

It's not all China but holy hell, a lot of spam sure comes from there, given how Golden Shield supposedly blocks internet access to the Chinese citizens. A friend of mine who lives in China (how he got past the firewall is beyond me, and he won't tell me either) told me that while incoming information is "regulated", they don't give half a shit about outgoing traffic to foreign countries. Hence all those shitty filter bag suppliers and whatnot. The Chinese government doesn't care.

So what is the alternative like, that would block based on content? Well there are a few solutions out there, namely SpamAssassin, ClamAV and Amavis among others. The problem is that they're all very memory intensive (especially compared to e.g. Postfix and Dovecot themselves) and that they must scan every email, and keep up with evasion techniques (such as putting the content in an image, or using characters from different character sets t̾h̾a̾t̾ ̾l̾o̾o̾k̾ ̾s̾i̾m̾i̾l̾a̾r̾).

But the thing is, all of that traffic comes from a certain few offending IP ranges, and an iptables rule that covers a whole range is very cheap. China (or any country for that matter) has too many IP ranges to block all of them. But the certain few offending IP ranges? I'll take a cheap IP-based filter over expensive content-based filters any day. And I don't want to be shamed for that.

I hate phonecalls so i rarely do them. Today my project lead called me with a question and he just couldnt hear me. This was my fourth phonecall in 2 years time with this phone. And everytime they couldnt hear me. After switching to speaker they do.

Today I found out that my pinky is blocking the mic since its on the left side of the charger port. I guess Ive got a phone for lefthanded people. I hope I remember this in six months.

I am at a hotel and these fuckers are blocking outbound connections to port 22. They are also blocking access to any websites mentioning proxy or vpn, seriously fuck them. I managed to get a VNC connection open to one of my servers and I am now trying to set up a VPN tunnel to my servers so I can fucking do my work. >:-(

Got the genius idea of multiplayer tic tac toe just before spring break. One week later, back in school and I have multiplayer tic tac toe written in Java. The only way that the school can block it is by blocking the port, but then I'll just change it until there are no more lol

give me suggestions on what to make next, this is fun

After doubting Deepin OS for 4 days and slangs to Windows, it turns out, ISP is blocking the port 22, which is why I was not able to communicate to my instance through SSH.

One of the major Cellular company and Fastest 4G in the whole country, 'Idea', is blocking the vital port 22. The same company promoted it's Internet service through chain of adv. calling it's Cellular Internet network, "Idea Internet Network (IIN)". Only to make it sound like IIT, IIMs ( elite indian colleges). Check on YouTube, IIN, if available

I was under fire right now.
One cellular company, Idea, whose Internet service works really good, was blocking port 22.
And other, BSNL, which works terrible at my home, and is not working recently, since last few days( Maybe be data pack was over ), atleast support port 22.

Just got the call from client who has to send sms to all its clients, immediately. So BSNL was not working. And Idea was not supporting port 22.
Still, I gave IDEA Cellular, a try, and luckily it worked today. They started supporting port 22, at the right time.
My ASS is Saved

fucking web hosts blocking all SMTP ports outgoing, forcing me to use PHP mail from their shitty blacklisted IP's.

Since I can't use a web api to send the mail Iended up setting up my home server to forward port 53 back out to the mail server, alot of hassle to get mail working :(

Fuck you Redis

Goes in a docker container, calls bgrewriteaof, get success, checks info - no pending writes, last write success.

Tries to scp to remote, fails - Unexpected AOF

Decides to shut down the local redis to be able to port, in case it's blocking it

Calls redis-cli shudown (expect to just shut redis down rigth)

It fucking deleted all my data, now I see the docs

"Flush the Append Only File if AOF is enabled."

Why the fuck? Fuck you redis, fuck you

I have one Windows and one Apple M1 computer. Our project runs old docker containers and can't upgrade easily. I decided to run the x86 versions of containers on there and use them from my network. Corporate Windows has port blocking so I decided to install linux to a usb drive. I loaded a live install distro and installed it to a second USB drive.
The internal nvme laptop drive somehow had its partition table wiped along the way. I can see files on there in a partition restore tool but alas it isn't becoming bootable again from uefi after doing partition table restore. 😭

Why the fuck do we have to use an antivirus that is so intrusive that it has so far wasted my time every day, because it thinks that blocking up random ports is okay. Its a fucking lottery every time I turn on the laptop. I wonder if its going to block port 3306 or 4200 tomorrow...

Architecture for Java REST API going to build/port from existing NodeJS one.
So Spring Boot + *

Lots of concurrent requests and large MongoDB calls. Current APIs use like 4GB memory for each instance because they don't use stream/pipe the response. Hold all data in memory and then return it all at once to user.

And well we expect more load in the future, so want to do this the right way.

So my understanding since this morning, is there's the blocking? MongoClient, (find* returns List) and now a Reactive MongoClient which is very async and like JS promises. Based on Pub, Sub model.

But the downside of JS promises was callback hell.

So actually 2 questions.
1. For each request, the db call done using the same MongoClient/db connection such that if there are 2 requests one would block the other?
2. Reactive Mongo would be non-blocking by design so would be better to support streamed responses?

Fuck you sophos. Fuck you hard. I moved a server to a new datacenter and it worked like a charm. Thank you windows and hyper-v. BUT! BUUUUUUT my fucking sophos worked like shit. Blocking everything by default? Yeah fuck you. Reconfigured everything. Still blocked and why? Forward “all“ doesnt mean forward all. Had to apply rules from port tcp 1 - 65335 and udp 1-65335. Nice you piece of fuck.
