Multi-line output in ss makes it difficult to search for things with grep. This new option will make it easier to find sockets matching certain criteria with simple grep commands. Example without option: $ ss -emoitn State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 127.0.0.1:13265 127.0.0.1:36743 uid:1974 ino:48271 sk:1 <-> skmem:(r0,rb2227595,t0,tb2626560,f0,w0,o0,bl0,d0) ts sack reno wscale:7,7 rto:211 rtt:10.245/16.616 ato:40 mss:65483 cwnd:10 bytes_acked:41865496 bytes_received:21580440 segs_out:242496 segs_in:351446 data_segs_out:242495 data_segs_in:242495 send 511.3Mbps lastsnd:2383 lastrcv:2383 lastack:2342 pacing_rate 1022.6Mbps rcv_rtt:92427.6 rcv_space:43725 minrtt:0.007 Example with new option: $ ss -emoitnO State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 127.0.0.1:13265 127.0.0.1:36743 uid:1974 ino:48271 sk:1 <-> skmem:(r0,rb2227595,t0,tb2626560,f0,w0,o0,bl0,d0) ts sack reno wscale:7,7 rto:211 rtt:10.067/16.429 ato:40 mss:65483 pmtu:65535 rcvmss:536 advmss:65483 cwnd:10 bytes_sent:41868244 bytes_acked:41868244 bytes_received:21581866 segs_out:242512 segs_in:351469 data_segs_out:242511 data_segs_in:242511 send 520.4Mbps lastsnd:14355 lastrcv:14355 lastack:14314 pacing_rate 1040.7Mbps delivery_rate 74837.7Mbps delivered:242512 app_limited busy:1861946ms rcv_rtt:92427.6 rcv_space:43725 rcv_ssthresh:43690 minrtt:0.007 Signed-off-by: Josh Hunt <johunt@akamai.com> Signed-off-by: David Ahern <dsahern@gmail.com> |

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
