Some times you may need to find/modify network related information in Linux/Unix systems. You can find most of the network related information from following table :

Network IP configuration :

AIX : lsattr -E -l inet0
HP-UX : /etc/rc.config.d/netconf
LINUX(RedHat): /etc/sysconfig/network-scripts/
Solaris : /etc/hostname.*

/etc/inet/*

/etc/defaultrouter


Hosts IP addresses :

AIX : /etc/hosts
HP-UX : /etc/hosts
LINUX(RedHat): /etc/hosts
Solaris : /etc/inet/hosts

Name service switch :

AIX : /etc/netsvc.conf
HP-UX : /etc/nsswitch.conf
LINUX(RedHat): /etc/nsswitch.conf
Solaris : /etc/nsswitch.conf

Network parameters :

AIX : no -a
HP-UX : ndd -h
LINUX(RedHat): sysctl -a | grep net
Solaris : ndd /dev/[tcp|ip] ?

Routing daemon :

AIX : gated
HP-UX : gated
LINUX(RedHat): routed
Solaris : in.routed

NIC Configurations :

AIX : ifconfig -a
HP-UX : lanscan -v
LINUX(RedHat): ifconfig -a
Solaris : ifconfig -a

Secondary IP Address :

AIX : ifconfig en0 alias IP
HP-UX : ifconfig lan0:1 IP
LINUX(RedHat): modprobe ip_alias

ifconfig eth0:1 IP
Solaris : ifconfig hme0:1 IP up

Login prompt :

AIX : HERALD @

/etc/security/login.cfg 
HP-UX : telnetd -b /etc/issue
LINUX(RedHat): /etc/issue
Solaris : BANNER @

/etc/default/telnetd

Increase the # of pseudo-terminals :

AIX : odmget -q "attribute=num and uniquetype=pty/pty/pty" PdAt | sed
"s/0-64/0-512/" |

odmchange -q "attribute=num and uniquetype=pty/pty/pty" -o PdAt

chdev -l pty0 -anum=256 -P

reboot

HP-UX : rebuild your kernel with these new values NPTY=# 

NSTRPY=#

reboot

insf -d ptys -n #

insf -d ptym -n #

insf -d pts -s # -e -v

 

LINUX(RedHat): cd /dev

./MAKEDEV -v pty

Solaris : {/etc/system}


set pt_cnt = #   {SYSV}

set npty = #      {BSD}

{/etc/iu.ap}

ptsl 0 # ldterm ttcompat

halt

boot -r


Maximum # of ptys :

AIX : 512
HP-UX : {MAXUSERS}
LINUX(RedHat): 256
Solaris : 176 {BSD}

3000 {SYSV}

Remote Shell :

AIX : remsh

rsh
HP-UX : remsh
LINUX(RedHat): rsh
Solaris : rsh

YP/NIS service binder :

AIX : /usr/lib/netsvc/yp/ypbind
HP-UX : /usr/lib/netsvc/yp/ypbind
LINUX(RedHat): /sbin/ypbind
Solaris : /usr/lib/netsvc/yp/ypbind
