SED: delete and print the only exact matched pattern
I am really need help with the regular expression in SED. From input file, I need to extract lines that have the port number (sport or dport) as defined. The input file is something like this
How can I possibly define the pattern if I only want the exact pattern match. If I only wanted port 4501, is it correct the way I defined in the first line of the sed file below?
The example of patterns in file p2pport-delete.sed are here:
Apart from that, I need to have copy of those deleted lines in different file. I am using pattern/p instead. Here is file p2pport-print.sed
However, from the output, I found out that the total lines deleted from p2pport-delete.sed and printed from p2pport-print.sed is different. This assure that my sed file is wrong.
I hope that I could get help from anyone that could help me.
Many thanks

Hi experts,
I have a file with regexes which is used for automatic searches on several files (40+ GB).
To do some postprocessing with the grep result I need the matching line as well as the match itself.
I know that the latter could be achieved with grep's -o option. But I'm not aware of a... (2 Replies)

dnet
DNET(8) BSD System Manager's Manual DNET(8)NAME
dnet -- dumb networking library test program
SYNOPSIS
dnet command args [...]
DESCRIPTION
dnet is a simple test program for the dnet(3) library. It can be used to compose and transmit network datagrams as a Unix-style filter (e.g.
reading from or writing to files and pipes) or modify the local system network configuration (including the ARP cache, firewall ruleset, net-
work interfaces, and routing table).
Payload generation commands
addr address [...]
Convert the address (specified as a hostname, IP address, or MAC address) into its binary representation on standard output.
hex string [...]
Convert the C-style escaped string (shellcode, for instance) into its binary representation on standard output.
rand len
Write len random bytes to standard output.
Packet encapsulation commands
eth [type type] [src mac] [dst mac]
Prepend the data read from standard input with an Ethernet header on standard output. The Ethernet type may be specified as 'arp', 'ip',
or as a hex, octal, or decimal number.
arp [op op] [sha mac] [spa host] [tha mac] [tpa host]
Prepend the data read from standard input with an ARP header on standard output. The ARP op may be specified as 'req', 'rep', 'revreq',
'revrep', or as a hex, octal, or decimal number.
ip [tos num] [id num] [off offset] [ttl num] [proto protocol] [src host] [dst dst]
Prepend the data read from standard input with an IP header on standard output. The fragmentation offset may be specified as a decimal
number (optionally concatenated with '+' to indicate more fragments) or as a hex number. The protocol may be specified by name, or as a
hex, octal, or decimal number.
icmp [type num] [code num]
Prepend the data read from standard input with an ICMP header on standard output.
tcp [sport port] [dport port] [flags flags] [seq num] [ack num] [win num] [urp num]
Prepend the data read from standard input with a TCP header on standard output. A port may be specified by name or hex, octal, or deci-
mal number. The TCP flags may be specified as some combination of the characters in the set 'SAFRPU' or as a hex number.
udp [sport port] [dport port]
Prepend the data read from standard input with a UDP header on standard output. A port may be specified by name or hex, octal, or deci-
mal number.
Packet transmission commands
send [device]
Read a packet from standard input and send it over the network. If no device is specified, the packet is assumed to be an IP datagram
and routed to its destination. Otherwise, the packet is assumed to be an Ethernet frame and is transmitted on the specified interface.
Kernel interface commands
arp show
Display the kernel ARP cache.
arp get host
Display the kernel ARP entry for host.
arp add host mac
Add an ARP entry mapping the mac address for host.
arp delete host
Delete the ARP entry for host.
fw show
Display the kernel firewall ruleset.
fw add|delete action direction device protocol src[:port[-max]] dst[:port[-max]] [type[/code]]
Add a rule to or delete a rule from the active firewall ruleset. The action must be either 'allow' or 'block'. The direction must be
either 'in' or 'out'. The device may specify an interface name, or 'any'. The protocol may be specified by name, or as a decimal num-
ber. For TCP and UDP protocols, a port (or range, if specified with a max value) may be specified in decimal and appended to the source
and/or destination address. For ICMP, a type (and optional code) may be specified in decimal.
intf show
Display the configuration of all network interfaces.
intf get device
Display the configuration for the interface specified by device.
intf set device [alias host] [dst host] [inet host] [link mac] [up|down] [arp|noarp]
Configure the interface specified by device.
route show
Display the kernel routing table.
route get dst
Display the route for the destination dst, specified as a hostname, IP address, or network prefix in CIDR notation.
route add dst gw
Add a route for the destination dst through the gateway gw.
route delete dst
Delete the route for the destination dst.
EXAMPLES
Send a UDP datagram containing random shellcode:
dnet hex "xebx1fx5ex89x76x08x31xc0x88x46x07x89"
"x46x0cxb0x0bx89xf3x8dx4ex08x8dx56x0cxcdx80"
"x31xdbx89xd8x40xcdx80xe8xdcxffxffxff/bin/sh" |
dnet udp sport 555 dport 666 |
dnet ip proto udp src 1.2.3.4 dst 5.6.7.8 | dnet send
Save an ARP request in a file and send it twice:
dnet arp op req sha 0:d:e:a:d:0 spa 10.0.0.3 tpa 10.0.0.4 |
dnet eth type arp src 0:d:e:a:d:0 dst ff:ff:ff:ff:ff:ff > arp.pkt
dnet send fxp0 < arp.pkt
dnet send fxp0 < arp.pkt
Send a fragmented ping packet:
# Create ping packet with IP header, to set ICMP checksum
echo "monkey monkey monkey monkey" | dnet icmp type 8 code 0 |
dnet ip proto icmp src 1.2.3.4 dst 5.6.7.8 > ping.pkt
# Chop off IP header
dd if=ping.pkt of=ping.data bs=20 skip=1
# Fragment IP payload
split -b 24 ping.data p.
# Send fragments
dnet ip id 1 off 0+ proto icmp src 1.2.3.4 dst 5.6.7.8 < p.aa |
dnet send
dnet ip id 1 off 24 proto icmp src 1.2.3.4 dst 5.6.7.8 < p.ab |
dnet send
