node js – Run NodeJS server through SSH without hanging from disconnect

I have a NodeJS server on a virtual machine. I connect to the machine through SSH and leave the server running with:

npm start &

If I disconnect with Ctl-D, the server keeps running. If my internet drops and the connection fails, the server also stops. Why does this happen, and how can I leave the server running without it dropping because of the internet disconnection?

Weird entry in SQL Server database, is this a result of SQL Injection?

I would like to ask about weird entries in SQL Server database.

So I stumbled upon a case where several database entries were updated. And the update is rather unusual.

So for example if I have an entry named:

Watermelon

The updated version is:

Watermelon<IMG SRC="/WF_SQL_XSRF.html">

The WF_SQL_XSRF.html file is not in the server, nor it was from internal people.
I did google and only a single Korean forum mentioned this and said “Watch your security.” But I didn’t find a single relevant documentation about this WF_SQL_XSRF thing. I know that the word XSRF is not a good sign already, but I just want to know what tool this might come from and is it common to have one.

I also find several other unattended website that has this line:

Thank you, I’ll update the question if needed.

security – Disabling OpenSSH server keys on OpenBSD: why the corresponding sshd_config entries are ignored and why ssh-keygen -A generates forbidden keys?

I am trying to achieve the followings on my OpenBSD 6.9 servers:

  1. Forbidding the use of all keys but the ssh-ed25519 one on both SERVER and CLIENT sides.
  2. Restricting ssh-keygen -A to generate keys only by the authorised ssh-ed25519 algorithm and nothing else.

In order to achieve these, I have added the following lines to my sshd_config:

HostKey /etc/ssh/ssh_host_ed25519_key
CASignatureAlgorithms ssh-ed25519
HostbasedAcceptedKeyTypes ssh-ed25519
HostKeyAlgorithms ssh-ed25519
PubkeyAcceptedKeyTypes ssh-ed25519

I have also added the following lines to my ssh_config:

CASignatureAlgorithms ssh-ed25519
HostbasedAcceptedKeyTypes ssh-ed25519
HostKeyAlgorithms ssh-ed25519
PubkeyAcceptedKeyTypes ssh-ed25519

I have deleted all keys but the authorised one.

Restarted sshd:

# rcctl restart sshd                                                                            
sshd(ok)
sshd(ok)

After verifying whether my settings are utilised by running the following commands:

# ssh -Q HostbasedAcceptedAlgorithms
# ssh -Q HostKeyAlgorithms
# ssh -Q PubkeyAcceptedAlgorithms

For my surprise, this is what they all return with:

ssh-ed25519
ssh-ed25519-cert-v01@openssh.com
sk-ssh-ed25519@openssh.com
sk-ssh-ed25519-cert-v01@openssh.com
ssh-rsa
rsa-sha2-256
rsa-sha2-512
ssh-dss
ecdsa-sha2-nistp256
ecdsa-sha2-nistp384
ecdsa-sha2-nistp521
sk-ecdsa-sha2-nistp256@openssh.com
webauthn-sk-ecdsa-sha2-nistp256@openssh.com
ssh-rsa-cert-v01@openssh.com
rsa-sha2-256-cert-v01@openssh.com
rsa-sha2-512-cert-v01@openssh.com
ssh-dss-cert-v01@openssh.com
ecdsa-sha2-nistp256-cert-v01@openssh.com
ecdsa-sha2-nistp384-cert-v01@openssh.com
ecdsa-sha2-nistp521-cert-v01@openssh.com
sk-ecdsa-sha2-nistp256-cert-v01@openssh.com

In other words, the key restrictions are ignored.

Just to be on the safe side, I have even restarted the server, but there is no difference.

A potential workaround is to remove all key files but the authorised one. However, the init script /etc/rc has a line, ssh-keygen -A, which regenerates all missing ssh keys after every system reboot, before the sshd daemon would start, including those of forbidden algorithms!

So removing the keys does not solve the problem.

As an additional workaround, I could remove the ssh-keygen -A line from the init script or replace it with my custom key generation algorithm, but that will lead back to where it has all started: having to deal with this problem over and over again, e.g. after every system update, whenever the OpenBSD team releases a new version of /etc/rc. Automating the removal of that line and testing such a sloppy workaround on large number of servers is difficult and it can lead to a massive network failure if something goes wrong.

Therefore, I continued my investigation and I dug into the source code of ssh-keygen. I have found out that it is not possible to restrict the behaviour of the -A switch from outside e.g. via config files. It does not even perform a preliminary test whether the keys are authorised or not, it just generates the keys, according to a list of algorithms from a hardcoded array. The only way of avoiding this is by editing, recompiling and using a custom fork of ssh-keygen and I will have to deal with it after every OpenSSH updates…

I have found a partial solution for other operating systems but not for OpenBSD.

Could somebody please point me to a proper solution? Why my sshd_config and ssh_config key restrictions are ignored and how to get ssh-keygen -A stop generating keys with forbidden algorithms?

Before anyone would ask: all other settings are utilised in both config files by OpenSSH, so these config files are indeed the actual ones being loaded.

Many thanks for all useful answers.

How to limit memory consumption of mysql server to prevent OOM kills?

My MySQL instance is getting killed by the Linux oom_killer due to huge consumption of memory by mysql when inserting into longblob columns. This occurs when restoring a mysqldump which contains a very large longblob column.

I’ve run through things like this blog which suggests setting various read/write buffers to different sizes in order to limit memory consumption. But despite the mentioned script outputting a “TOTAL (MAX)” memory of 350MB after tweaks, mysql will still happily gobble up gigabytes of memory before eventually getting killed.

Here’s a reproduction via Docker:

docker run -p 3306:3306 -e MYSQL_ROOT_PASSWORD=foobar -d --name mysql-longblob mysql:5.7

mysql -h 127.0.0.1 -P 3306 -u root --password -e "CREATE DATABASE blobs; USE blobs; CREATE TABLE longblob_test (bigcol LONGBLOB NOT NULL) ENGINE = InnoDB;"

mysql -h 127.0.0.1 -P 3306 -u root --password -e 
 "SET GLOBAL max_allowed_packet=536870912;" # 512MB

mysql -h 127.0.0.1 -P 3306 -u root --password -D blobs -e "source ./500MB.sql"

In this case, docker stats reported consumption of ~1.8GB memory before it got OOM killed for exceeding its limit. At idle, mysql was reporting ~200MB memory.

Where 500MB.sql is a file inserting a 500MB blob of text in the shape:

INSERT INTO longblob_test VALUES ('500MB_WORTH_OF_TEXT_HERE')

So a couple of questions:

1) Why does mysql need to eat 1.6GB of memory to ingest a 500MB column?

2) How do I set a hard upper limit on mysql to prevent it ever exceeding “x” amount of memory?

P.S: You might be tempted to tell me that this is very silly, and you shouldn’t be storing 500MB+ blobs in a database. I absolutely 100% agree! But it’s an unfortunate situation, and rearchitecting the data storage is not possible in this situation.
