N-T-P: Need to update
Below are the list that I came across and waiting to update in my blog:
Below are the list that I came across and waiting to update in my blog:
- select vs poll vs epoll ----- select can be used as server listening for client
- How does xinetd works
- Connecting to a Linux desktop through VNC.
- Need to discuss on how to handle when linux is stuck(we can use ctrl-alt-f2 to go to the terminal prompt and the see the process which stuck and kill it) and ctrl-alt-f1(in fedora) ctrl-alt-f7(in ubuntu) to switch back to gui prompt.
- on linux firewalls, iptables -L -n will list the firewalls and "service iptables stop" will stop the firewalls and "service iptables start" will start the firewall and "service iptables status" will give the status of the firewall
- UDP server is different from TCP server, it doesn't need to listen & accept
- When the TCP server establishes the connection with the client through accept, a new connection will be created with new fd, does this fd will be having different TCP port??
- Write fds in select is used to avoid blocking writes.
- "module is unknown" error on ubuntu.. solution for this...a) Open /etc/pam.d/login b) Search for pam_limits.so in the file c) replace /lib/security/pam_limits.so to /lib/i386-linux-gnu/security/pam_limits.so....Now the error shouldn't come and you should be able to login :-).... or for the last try doing "sudo pam-auth-update --force"
