I have a opensuse Linux server with two nics.
eth0 = internal network with 172.16.1.24
eth1 = external network with ip 172.19.3.2
Internal networks: 172.16.0.0/16, 172.17.0.0/16 and 192.168.0.0/16.
External network: 172.19.3.0/16
The default gateway is 172.19.3.1 on eth1.
IP Forwarding is disable. Only a Proxy Server on this server ist running, so only local access to the external network is required. But all hosts in the several local subnets must reach the server.
My problem is, that the internally networks 172.17.0.0/16 and 192.168.0.0/16 on eth0 I can't reach.
can someone explain the meaning of the following shell commands:
1. who / wc -l
2. who / sort > user_names
3. cat students > new_students
4. current_day='date / cut -cl-3'

wanboot_keygen
wanboot_keygen(1M) System Administration Commands wanboot_keygen(1M)NAME
wanboot_keygen - create and display client and server keys for WAN booting
SYNOPSIS
/usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=3des
/usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=aes
/usr/lib/inet/wanboot/keygen -m
/usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=sha1
/usr/lib/inet/wanboot/keygen -d -m
/usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=keytype
DESCRIPTION
The keygen utility has three purposes:
o Using the -c flag, to generate and store per-client 3DES/AES encryption keys, avoiding any DES weak keys.
o Using the -m flag, to generate and store a "master" HMAC SHA-1 key for WAN install, and to derive from the master key per-client HMAC
SHA-1 hashing keys, in a manner described in RFC 3118, Appendix A.
o Using the -d flag along with either the -c or -m flag to indicate the key repository, to display a key of type specified by keytype,
which must be one of 3des, aes, or sha1.
The net and cid arguments are used to identify a specific client. Both arguments are optional. If the cid option is not provided, the key
being created or displayed will have a per-network scope. If the net option is not provided, then the key will have a global scope. Default
net and code values are used to derive an HMAC SHA-1 key if the values are not provided by the user.
OPTIONS
The following options are supported:
-c
Generate and store per-client 3DES/AES encryption keys, avoiding any DES weak keys. Also generates and stores per-client HMAC SHA-1
keys. Used in conjunction with -o.
-d
Display a key of type specified by keytype, which must be one of 3des, aes, or sha1. Use -d with -m or with -c and -o.
-m
Generate and store a "master" HMAC SHA-1 key for WAN install.
-o
Specifies the WANboot client and/or keytype.
EXAMPLES
Example 1: Generate a Master HMAC SHA-1 Key
# keygen -m
Example 2: Generate and Then Display a Client-Specific Master HMAC SHA-1 Key
# keygen -c -o net=172.16.174.0,cid=010003BA0E6A36,type=sha1
# keygen -d -c -o net=172.16.174.0,cid=010003BA0E6A36,type=sha1
Example 3: Generate and Display a 3DES Key with a Per-Network Scope
# keygen -c -o net=172.16.174.0,type=3des
# keygen -d -o net=172.16.174.0,type=3des
EXIT STATUS
0
Successful operation.
>0
An error occurred.
