Hello,
I'm a Solaris admin like your self. I don't use DHCP for my servers, I set static IPs. I use the GUI tools below for RHEL, that can be launched from the command line, when I need to do more then just set a static IP.
Use this command if you want to use a X-Window GUI to change the IP address.
Use this command to launch a utility inside your terminal. In other words this should work on a headless server.
I hope this helps you out.
Hi all...
In my Unix system a program exists called "daemon2" which is responsible to enqueue program executions. For example, if I want to make the system to enqueue lpr executions for certain users, I call daemon2 with lpr as the parameter.
Is there an equivalent in Linux?
Thanks

iostat -e gives the soft, hard and transport error information in Solaris.
What is the equivalent command in the other flavors of Unix AIX HP Linux.
Thanks

In IBM Mainframe they have something called ACF2 rule which is essentially used to control the dataset access. It is kind of a list-based access control for mainframe datasets.
Is there anything equivalent to ACF2 available in Unix ?
Thanks

I have experience with making bootable images of AIX systems using mksysb and wondered if there was some type of equivalent software for Linux. Or perhaps some of the folks here have alternatives or unique ideas for how they are backing up their Linux systems enabling them to recover them as... (13 Replies)
I moved to a Linux system from Windows a few months ago. Most of the programs I had been using were already native to Linux (Firefox, the GIMP, Pari, etc.) and most others I found a close enough program (Crimson Editor -> gedit, Visual Studio -> KDevelop, Primo -> Morain's ECPP).

Hi All,
I have an issue with calculating the network number that needs to be put in /etc/netmasks file in my Sol-9 server.
The IP of my server in 10.164.114.135
Default Gateway - 10.164.114.130
Netmask - 255.255.255.240
If I set "10.164.114.130 255.255.255.240" in netmask file, after... (2 Replies)
Hello, I'm writing a multi-threaded socket server in C++ and I needed something like wsaasyncselect to handle messages like fd_accept, fd_read, fd_connect, fd_close.

Hi,
I need to mount a replicated nfs4 export on a number of AIX and Redhat hosts. To get the failover on the clients working smoothly, I need to change certain values on the AIX boxes like nfs_v4_fail_over_timeout, timeo and retrans values. Since I have no clue about Linux, I am not quite sure... (1 Reply)

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.
