Lost Internet

Product : Linux.
Part involved : Squid.
Summary : Users can not access to internet.
Scenario : Troubleshooting internet service of end users .
Company : National Institute of Cancer Sickness of Peru (INEN).
Reference date : May 2005.

The main functionality of internet connection is based on "rcinetd" service running on Linux, then is possible to get up it swaping the states of that service, such as :

/etc/inetd.conf
rcinetd restart
cd /var/spool/mail
vdir
du -h
tail -f /var/log/mail
tail -f /var/log/httpd/access_log
tail -f /var/squid/logs/access.log
last more
vi /etc/passwd
bi /etc/shadow

And, after that, it persists a lost of internet service then try with ping command from your gateway to outside if there exists any other response, in negative answers check your connection with your ISP.
