Configuring network devices

Solaris

vi /etc/hostname.*
vi /etc/hosts
vi /etc/netmasks

Debian:

vi /etc/network/interfaces

Redhat:

cd /etc/sysconfig/network-scripts
vi ifcfg-*

Bundled SSL certs

rhel4:

up2date openssl
ls -l /usr/share/ssl/cert.pem
ls -l /usr/share/ssl/certs/ca-bundle.crt
ls /usr/share/ssl/certs/

rhel5

yum install openssl
ls -l /etc/pki/tls/cert.pem
ls -l /etc/pki/tls/certs/ca-bundle.crt
ls /etc/pki/tls/certs

Debian:

aptitude install ca-certificates
ls /usr/share/ca-certificates

OSX native

ls /System/Library/OpenSSL/certs

OSX fink

fink install ca-roots
ls /sw/etc/ssl/certs

Package management

Solaris

## list installed pkgs:
pkginfo
## look for a desired GT pkg:
mount /ts_install; ls /ts_install/packages

## download and install a desired GT pkg:
mount /ts_install; cd /ts_install/packages; instpkgs GTscreen
## remove an installed pkg:
mount /ts_install; pkgrm -n -a /ts_install/packages/admin GTscreen

## detailed info on a pkg:
pkginfo -l GTscreen

## list of files in a pkg:
~willday/bin/pkgfiles GTscreen
egrep GTscreen /var/sadm/install/contents
## what pkg contains the file:
~willday/bin/pkgfiles -r /usr/local/bin/screen
egrep /usr/local/bin/screen /var/sadm/install/contents

Debian:

## list installed pkgs:
dpkg -l
COLUMNS=300 dpkg -l
## look for a desired pkg:
dpkg -l "*ssh*"
apt-cache search ssh

## download and install a desired pkg:
aptitude install strace
## remove an installed pkg:
aptitude purge strace

## detailed info on a pkg:
dpkg -p coreutils

## list of files in a pkg:
dpkg -L coreutils
## what pkg contains the file:
dpkg -S /bin/ls

## update the OS
aptitude update
aptitude dist-upgrade

http://www.debian.org/doc/FAQ/ch-pkgtools.en.html

Redhat (rhel generic):

## List installed pkgs:
rpm -qa

## Remove an installed pkg:
rpm -e strace

## Detailed info on a pkg:
rpm -qi coreutils

## List of files in a pkg:
rpm -ql coreutils
## What pkg contains the file:
rpm -qf /bin/ls

## Remove a specific-architecture pkg:
rpm -e e2fsprogs.i386

## Check signature on a pkg
rpm --checksig foo.rpm
## Import and trust a GPG key; NOTE if the key had been previously 
##   imported this *will* create a duplicate in the rpm db, 
##   which is a pain
rpm --import foo.asc
## Remove a trusted signature, even if it's been imported multiple times
rpm -e --allmatches gpg-pubkey-d763e80a-39c90df1

## View all trusted GPG keys
rpm --qa "gpg-pubkey*"
## View a specific trusted GPG key
rpm -qi gpg-pubkey-db42a60e-37ea5438

## Sign an rpm (replaces any existing signatures)
rpm --resign foo.rpm

Redhat (rhel4-specific):

## Update the OS
up2date -u

## Look for a desired pkg:
up2date --showall | egrep ssh

## Download and install a desired pkg:
up2date strace

## Fetch an rpm file.  Look in /var/spool/up2date.
up2date --get strace

Redhat (rhel5-specific):

## Update the OS
yum update

## Look for a desired pkg:
yum list all | egrep ssh

## Download and install a desired pkg:
yum install strace
