I know how to ping in Perl. That is easy. What I am wondering is if there is a way for Perl to determine whether the ping was successful or not. Or do I need to save the results out and parse the results seperately looking for the #of tries and successful revieves.
Thanks. (1 Reply)

Running 3650 switch. I have this odd issue where I cannot get 4 new Centos 7 boxes pinging out on public IPs (nor pinging in), only gateway .1 and first public IP .2

dhcp(5) Standards, Environments, and Macros dhcp(5) NAME
dhcp - Dynamic Host Configuration Protocol DESCRIPTION
Dynamic Host Configuration Protocol (DHCP) enables host systems in a TCP/IP network to be configured automatically for the network as they boot. DHCP uses a client/server mechanism: servers store configuration information for clients, and provide that information upon a client's request. The information can include the client's IP address and information about network services available to the client. This manual page provides a brief summary of the Solaris DHCP implementation. Solaris DHCP Client The Solaris DHCP client is implemented as background daemon, dhcpagent(1M). This daemon is started automatically during bootup if there exists at least one dhcp.interface file in /etc. Only interfaces with a corresponding /etc/dhcp.interface file are automatically configured during boot. Network parameters needed for system configuration during bootup are extracted from the information recieved by the daemon through the use of the dhcpinfo(1) command. The daemon's default behavior can be altered by changing the tunables in the /etc/default/dhc- pagent file. The daemon is controlled by the ifconfig(1M) utility. Check the status of the daemon using the netstat(1M) and ifconfig(1M) commands. Solaris DHCP Server The Solaris DHCP server is implemented as a background daemon, in.dhcpd(1M). This daemon can deliver network configuration information to either BOOTP or DHCP clients. The Solaris DHCP service can be managed using the dhcpmgr(1M) GUI or the command line utilities dhcpcon- fig(1M), dhtadm(1M), and pntadm(1M). DHCP Configuration Tables The Solaris DHCP server stores client configuration information in the following two types of tables: dhcptab tables Contain macros and options (also known as symbols), used to construct a package of configuration information to send to each DHCP client. There exists only one dhcptab for the DHCP service. The dhcptab(4) can be viewed and mod- ified using the dhtadm(1M) command or dhcpmgr(1M) graphical utility. See dhcptab(4) for more information about the syntax of dhcptab records. See dhcp_inittab(4) for more information about the DHCP options and symbols. DHCP network tables DHCP network tables, which contain mappings of client IDs to IP addresses and parameters associated with those addresses. Network tables are named with the IP address of the network, and can be created, viewed, and modified using the pntadm command or dhcpmgr graphical utility. See dhcp_network(4) for more information about network tables. SEE ALSO
