comment Sound is gone after booting system in text mode
@Benedictus It's been a long time since I used sound on a text only system. I did install a command line mixer. It should depend on or load the relevant devices.

comment IS there any way to send mail without relay server
@KALAISELVAN You can send mail without an MX record. Large organizations often use dedicated servers for outbound mail that are not listed as an MX. You can only receive mail without an MX record if the A record resolves to the IP address of your mail server. However, I would recommend using an MX pointing to a mail server's A record.

comment What is stopping our UDP packets (how does it know the route is down)?
@JohnU If you are accepting and dropping the packets, then I would be concerned you get the same behavior when you aren't dropping packets. Depending on your filter Wireshark may not be catching the ICMP packets.

comment Why and how is swap improving performance, and can I disable it?
@prakharsingh95 Things paged out to disk tend not to be frequently accessed. If they are using memory that would otherwise be used for frequently accessed, they may increase the I/O load (use of disk). This is trading off space used for swap for performance resulting from fewer waits for disk I/O.

comment How many inodes do I need to access to read a file?
@graphtheory92 The root directory is just another inode. However it is a very important inode. When you mount a disk partition, its root partions inode is referenced in place of the inode of the mount point on the disk you are mounting to.
