comment how to get a subset of NTP servers from *.pool.ntp.org?
On pool.ntp.org/en/use.html they say, that the servers change hourly (unless one fails and is replaced). Can you check that by asking only every hour?

comment Clear the arp cache on linux, really
Are you short of arp table entries? Maybe there's a program asking for that IP, thus renewing that entry. Check with wireshark or tcpdump.

You're not showing your log? Maybe others or me detect something suspicious?

The connection is waiting for an ACK. Can you look at the network traffic with wireshark or tcpdump?

comment Large number of ssh login attempts
The providers from China should have an abuse-contact in their whois-entries, you can complain there (only once, not for every attempt). And for the one from verizon, go and complain at the FBI (also only once).

comment Not getting httpd dump on segfault
Have you tried to run the server with strace (redirecting output to a file)? It will slow it down a lot tho, and the segfault may not happen then.

comment unable to login remotely in MYSQL
Try the hints from cyberciti.biz/tips/… - otoh it is more secure to ssh to the host and access mysql from there. For a GUI use phpmyadmin.

comment unable to login remotely in MYSQL
My,fault, it should be netstat -n | grep 3306. I saw you tried port 3307 too?

Run that command from an xterm or a console.

Do you find 3306 in the output of netstat -rn on the server? Are there any firewall rules preventing access to that port?

comment Wake-on-LAN: Unicast is not working. Why?
WOL-packets can be sent as UDP broadcasts too, if that helps.

comment Wake-on-LAN: Unicast is not working. Why?
Sending to a specific IP-address means that it's already in the ARP-table - which can't be if it's still down. Look at this with wireshark or tcpdump.

You can try if one of the users is allowed to run the chsh command with sudo.

Suse should have the chsh command. It does just that what you have in mind. Check the manpage.

comment Why iptables block my port 80 traffic?
You have only 3 rules for port 80. Disable them. 1) Does it work now? Yes: enable another rule, go to 1). No: Disable another rule, go to 1)

comment How to let 'cp' command don't fire an error when source file does not exist?
The simple pipe | is always run while || is only done in case of an error. And true is usually a binary while the colon : is a builtin and doesn't consume a PID.
