Hello Friends I am Deepak Saini and tody I m tell you some about of unnecessary services
Not a big topic but important to discus
Lets start
Unnecessary service on the server
1 Portmap ,Rpc.mountd,Rpc.nfsd
2 Smbd and Nmbd
3 Automounter
4 Named
5 Lpd
1 Portmap ,Rpc.mountd , rpc.nfsd :- These are all the part of the NFS subsystem.Are you running an NFS server ? Do you need to mount remote NFS shares ?Unleess you answered yes to either of these question,you don't need these daemons running.Reclaim the resources that they are taking up eliminate the potential security risk.
2 Automounter :- The automounter can be handy to bring up networks(or local)file systems on demand eliminating the need for root privileges when accessing them. this is especially handy on client desktop machines ,where a user need to use removable media (such cd ,pd,floopy disk )or to access network resources.But on a dedicated server ,the automounter is probably unnecessary.So we are kill the service
3 Smbd and Nmbd :- These are the samba daemons ,Do you need to export SMB shares to Windows boxes (or Other Machines)?If not then these processes can be safely killed.
4 Named :- Are you running a name server ? You don't ned named running of you only need to resolve network names;thats what /etc/resolv.conf and the only need to bind libraries are for .Unless you're running name services for other machine,or ar running a caching DNS server (see setting up caching DNS with authority for local Domains "(#78),Then named isn;t needed.
5 Lpd :- Do you ever print to this machine ? Chances are ,If its serving Internet resources,it shouldn't be accepting print rewuests anyway .Remove the printer daemon if you aren't plainng on usning it .
There are many other serivces which we are not using on the server but they are running by defaults or we not kill those so find and kill those service.
Thanks for reading And srry for my R.I.P english
