What files and folders in tmp/ folder
Hi,
My linode got restricted as there was the support has detected an Outbound Denial of Service attack on my linode.
I follow the guide from the linode support team (https://www.linode.com/community/questions/467/ive-noticed-some-suspicious-activity-on-my-linode-what-do-i-do) and checked the tmp folder. My tmp folder has the follwing files and folders
drwxrwxrwt 10 root root 4096 Jun 17 06:09 .
drwxr-xr-x 23 root root 4096 Jun 15 08:58 ..
drwxrwxrwt 2 root root 4096 Jun 17 00:14 .font-unix
drwxrwxrwt 2 root root 4096 Jun 17 00:14 .ICE-unix

drwxrwxrwt 2 root root 4096 Jun 17 00:14 .Test-unix
drwxrwxrwt 2 root root 4096 Jun 17 00:14 .X11-unix
drwxrwxrwt 2 root root 4096 Jun 17 00:14 .XIM-unix
Are those folder looking good or should I delelte some of them, and if so which ones?
I appreciate everyone's help. Thank you.

You write:

ARRRGGGGHHH!! There are no "folders"…there are "directories"! I digress…

Theres that word again!
All the directories matching the pattern *service* belong to systemd -- the Linux system service management daemon. See:
https://www.linode.com/docs/quick-answers/linux-essentials/what-is-systemd/
All the directories matching the pattern *-unix$ belong to the X Window System.
All of these are perfectly normal. If your Linode does not run a desktop environment that requires X11, you can delete all the *-unix$ directories. Your system will go seriously haywire if you delete the *service* directories!

Thank you very much for your fast reply and the correction, I appricate it.
As I'm not so much familiar with the whole server side, as I usually take care of the front end, can I ask you one or two more questions?
Do the running processes look okay?

Just as a practical note… When you have screen output like this, enclose it between lines consisting of 3 backquotes (```). Doing so will present the text between as "code" and make your post a lot more readable. That being said, the only processes you presented in your list that aren't normally there were these:

But this is you doing your ps -aux

Do the connections look okay?
Just as another practical matter, it's not a very good idea to publish your IP address(es) or domain name(s) in an open forum like this (you never know who might be scanning the posts here for such information):
tcp 0 1 178.79.181.108:57286 45.9.148.99:443 SYN_SENT
tcp 0 1 178.79.181.108:46692 104.223.142.164:3307 SYN_SENT
The first of these is an https connection from 45.9.148.99 (registered in the Netherlands). I don't recognize the second one. It's a TCP connection on port 3307 to your Linode from an IP address in the US. According to /etc/services, port 3307 is listed as:
opsession-prxy 3307/udp # OP Session Proxy
opsession-prxy 3307/tcp # OP Session Proxy
I don't know what OP Session Proxy is…maybe someone else can explain. I'd investigate this further…
The rest of the TCP connections and all of the UDP connections are normal (DNS, ICMP, ssh, http, etc).
The connections labeled unix never go outside the boundaries of your system ("unix" is shorthand for "unix-domain sockets"…these were named when TCP/IP was the province of Unix systems only…since about the mid-1980s or so, the proper term for them is "local-domain sockets" to reflect that TCP/IP no longer belongs to Unix exclusively and communication over them is always local). These are all related to normal system/application services.
I get the following when I check the ports
lsof -i tcp:3306 -P -R
Port 3306 is the well-known port for mysql. This is normal.
lsof -i tcp:53 -P -R (n.b., this command was implied from context)
Port 53 is DNS…also normal
lsof -i tcp:57286 -P -R and lsof -i tcp:46692 -P -R
Ports 57286 and 46692 are temporary ports the system has allocated to handle the inbound TCP connections from IP addresses 45.9.148.99 and 104.223.142.164 respectively that I discussed above. Provided the communication is legitimate, these are legitimate as well.
As I said before, I would investigate the use of port 3307 further. It may be innocuous but, not knowing anything about what your system does, I just can't tell. If it's not legitimate, you can close access to the port in your firewall with relative ease.

Thank you again for you help. I really do appreciate the time you spend on look into it and the knowdledge you share.
Just as a practical note… When you have screen output like this, enclose it between lines consisting of 3 backquotes (```). Doing so will present the text between as "code" and make your post a lot more readable.

Thanks for the notes, have just update my posts :)

I will look into it, and hopefully will find some valuable information.
Thank you again for your help :)
