Resetting ifconfig rx and tx value:
By default the rx and tx value get reset when ever the system get restart, but it is possible to do the same manually too, without the restarting the system.
Few Notes:
1. We get the rx and tx value from the ifconfig command.
2. It help us to find how much data came into the system and how much data went outside of the system
3. "rx" let us know about how much data came into (in coming ) the system
4. "tx" let us know about how much data went out (out going or data out ) from the system.
5. These information can also be found at "/proc/net/dev"[1] file
So, How do reset these information without restarting the system:
NOTE: This is a hacker way, to mask or delete these information, but the only way to save our server is to know how the hacker do this and how can we stop it or how to find that the system got hacked or so.
1. If you are doing from a remote system, then make sure that you are running this command with nohup and as root access.
2. Find the network driver information. [ example: "ethtool -i eth0"[2] or "ethtool -i wlan0"[3] ]
3. nohup sudo modprobe -r ath9k; sudo modprobe ath9k; sudo ifup wlan0 [ as example giving my system's wlan0 driver information ]
4. Note that the how will go out of network for some time in this case. [4]
Few more info:
1. You can find this command at the history file: as [ sudo modprobe -r r8169 ; sudo modprobe r8169 ; ifup eth0 ]
2. But a history can be cleared with -c option.
3. Check for some information at "/var/log/auth.log"[5] file. [ file at ubuntu os ]
4. Check for some information at "/var/log/kern.log"[6] file.
5. Check for some information at "/var/log/syslog"[7] file.

By default the rx and tx value get reset when ever the system get restart, but it is possible to do the same manually too, without the restarting the system.
Few Notes:
1. We get the rx and tx value from the ifconfig command.
2. It help us to find how much data came into the system and how much data went outside of the system
3. "rx" let us know about how much data came into (in coming ) the system
4. "tx" let us know about how much data went out (out going or data out ) from the system.
5. These information can also be found at "/proc/net/dev"[1] file
So, How do reset these information without restarting the system:
NOTE: This is a hacker way, to mask or delete these information, but the only way to save our server is to know how the hacker do this and how can we stop it or how to find that the system got hacked or so.
1. If you are doing from a remote system, then make sure that you are running this command with nohup and as root access.
2. Find the network driver information. [ example: "ethtool -i eth0"[2] or "ethtool -i wlan0"[3] ]
3. nohup sudo modprobe -r ath9k; sudo modprobe ath9k; sudo ifup wlan0 [ as example giving my system's wlan0 driver information ]
4. Note that the how will go out of network for some time in this case. [4]
Few more info:
1. You can find this command at the history file: as [ sudo modprobe -r r8169 ; sudo modprobe r8169 ; ifup eth0 ]
2. But a history can be cleared with -c option.
3. Check for some information at "/var/log/auth.log"[5] file. [ file at ubuntu os ]
4. Check for some information at "/var/log/kern.log"[6] file.
5. Check for some information at "/var/log/syslog"[7] file.
