Abstract

Example implementations relate to server access times. A computing device may comprise a processing resource; and a memory resource storing non-transitory machine-readable instructions to cause the processing resource to: determine a media access control (MAC) address of a server; poll a top of rack (TOR) switch connected to the server to capture a packet; determine a source MAC address using the captured packet; determine, based on the source MAC address, an identity of a user computing device; and log, based on a time included in the captured packet, a time the user computing device last accessed the server.

Claims

1. A computing device, comprising:

a processing resource; and

a memory resource storing non-transitory machine-readable instructions to cause the processing resource to;

locate the server having the determined MAC address by parsing a predetermined server configuration file;

determine a media access control (MAC) address of a server;

poll a top of rack (TOR) switch connected to the server to capture a packet;

determine a source MAC address using the captured packet;

determine, based on the source MAC address, an identity of a user computing device; and

log, based on a time included in the captured packet, a time the user computing device last accessed the server.

2. The computing device of claim 1, including instructions to cause the processing resource to determine:

a management internet protocol (IP) address, username, and password of the TOR switch; and

a username and password of the server.

3. The computing device of claim 2, including instructions to cause the processing resource to determine the MAC address of the server by logging in to the server utilizing:

the management IP address, username, and password of the TOR switch; and

the username and password of the server.

4. The computing device of claim 1, including instructions to cause the processing resource to determine the identity of the user computing device by comparing the source MAC address to a predetermined database.

5. The computing device of claim 4, wherein the predetermined database is a lightweight directory access protocol (LDAP).

6. The computing device of claim 1, including instructions to cause the processing resource to poll the TOR switch using sampled flow (sFlow).

7. The computing device of claim 1, wherein the predetermined server configuration file includes:

the management IP address, username, and password of the TOR switch; and

the IP address of the server, username, and password of the server.

8. The computing device of claim 1, wherein:

the server is included in a server rack having a plurality of servers; and

the TOR switch is connected to the plurality of servers.

9. A non-transitory computer readable medium storing instructions executable by a processing resource to cause the processing resource to:

parse a predetermined server configuration file to locate a server;

determine a media access control (MAC) address of the server by logging in to the server utilizing login credentials of;

the server; and

a top of rack (TOR) switch connected to the server;

poll the TOR switch connected to the server to capture a packet, wherein the packet includes a source internet protocol (IP) address and a destination IP address;

determine, based on the source IP address, an identity of a user computing device; and

log, based on a time included in the captured packet, a time the user computing device last accessed the server.

10. The medium of claim 9, wherein the server is allocated to the user computing device.

11. The medium of claim 10, including instructions to re-allocate the server from the user computing device in response to the time the user computing device last accessed the server exceeding a threshold amount of time.

12. The medium of claim 10, including instructions to generate a notification to the user computing device in response to the time the user computing device last accessed the server exceeding a threshold amount of time.

13. The medium of claim 9, including instructions to determine a source MAC address using the source IP address by polling an address resolution protocol (ARP) table of the TOR switch.

14. The medium of claim 9, including instructions to determine a source MAC address using the source IP address by polling an address resolution protocol (ARP) table of a switch connected to the user computing device.

15. A method, comprising:

parsing, by a computing device, a predetermined server configuration file to locate a server among a plurality of servers included in a server rack, wherein the predetermined server configuration file includes;

internet protocol (IP) addresses and login credentials for each server in the server rack; and

an IP address and login credentials of a top of rack (TOR) switch for the server rack;

determining, by the computing device, a media access control (MAC) address of the server by logging in to the server utilizing the login credentials of the server and the TOR switch;

polling, by the computing device, the TOR switch to capture a packet, wherein the packet includes a source IP address;

determining, by the computing device, a source MAC address using the source IP address;

determining, by the computing device, an identity of a user computing device by comparing the source MAC address to a lightweight directory access protocol (LDAP); and

logging, by the computing device based on a time included in the captured packet, a time the user computing device last accessed the server.

16. The method of claim 15, wherein the method includes logging the time the user computing device last accessed the server in a user mapping table, wherein the user mapping table includes at least one of:

IP and MAC addresses of each of the plurality of servers;

IP addresses of users of each of the plurality of servers;

a last accessed time of user computing devices of each of the plurality of servers; and

user identification information corresponding to each of the user computing devices.

17. The method of claim 16, wherein the method includes adding, in response to a particular server of the plurality of servers included in the predetermined server configuration file being deleted from the predetermined server configuration file, the deleted server to a deleted server list.

18. The method of claim 17, wherein the method includes:

parsing the deleted server list for the deleted server; and

removing the deleted server from the user mapping table.

19. The method of claim 15, wherein the method is performed at predetermined intervals.
