Ejemplos de uso de lsof

lsof

lsof is the Linux/Unix über-tool. I use it most for getting network connection related information from a system, but that's just the beginning for this amazing and little-known application. The tool is aptly called lsof because it "lists open files". And remember, in Unix just about everything (including a network socket) is a file.

** lsof is also the Linux/Unix command with the most switches. It has so many it has to use both pluses and minuses.

usage: [-?abhlnNoOPRstUvV] [+|-c c] [+|-d s] [+D D] [+|-f[cgG]]  [-F [f]] [-g [s]] [-i [i]] [+|-L [l]] [+|-M] [-o [o]]  [-p s] [+|-r [t]] [-S [t]] [-T [t]] [-u s] [+|-w] [-x [fl]] [--] [names] 

As you can see, lsof has a truly staggering number of options. You can use it to get information about devices on your system, what a given user is touching at any given point, or even what files or network connectivity a process is using. lsof replaces my need for both netstat and ps entirely. It has everthing I get from those tools and much, much more.

Show Your Network Connections

Show all connections with -i

lsof -i

COMMAND  PID USER   FD   TYPE DEVICE SIZE NODE NAME dhcpcd 6061 root 4u IPv4 4510 UDP *:bootpc sshd 7703 root 3u IPv6  6499 TCP *:ssh (LISTEN) sshd 7892 root 3u IPv6  6757 TCP 10.10.1.5:ssh->192.168.1.5:49901 (ESTABLISHED) 

Show only TCP (works the same for UDP)

lsof -iTCP

COMMAND  PID USER   FD   TYPE DEVICE SIZE NODE NAME sshd 7703 root 3u IPv6 6499 TCP *:ssh (LISTEN) sshd 7892 root 3u IPv6 6757 TCP 10.10.1.5:ssh->192.168.1.5:49901 (ESTABLISHED) 

-i :port shows all networking related to a given port

lsof -i :22

COMMAND  PID USER   FD   TYPE DEVICE SIZE NODE NAME sshd 7703 root 3u  IPv6 6499 TCP *:ssh (LISTEN) sshd 7892 root 3u  IPv6 6757 TCP 10.10.1.5:ssh->192.168.1.5:49901 (ESTABLISHED) 

To show connections to a specific host, use @host

lsof -i@192.168.1.5

sshd 7892 root 3u IPv6 6757 TCP 10.10.1.5:ssh->192.168.1.5:49901 (ESTABLISHED) 

Show connections based on the host and the port using @host:port

lsof -i@192.168.1.5:22

sshd 7892 root 3u IPv6 6757 TCP 10.10.1.5:ssh->192.168.1.5:49901 (ESTABLISHED) 

Grepping for "LISTEN" shows what ports your system is waiting for connections on

lsof -i| grep LISTEN

iTunes     400 daniel   16u  IPv4 0x4575228  0t0 TCP *:daap (LISTEN) 

Grepping for "ESTABLISHED" shows current active connections

lsof -i| grep ESTABLISHED

firefox-b 169 daniel  49u IPv4 0t0 TCP 1.2.3.3:1863->1.2.3.4:http (ESTABLISHED) 

Working with Users, Processes, and Files

You can also get information on various users, processes, and files on your system using lsof:

Show what a given user has open using -u

lsof -u daniel

-- snipped -- Dock 155 daniel  txt REG   14,2   2798436   823208 /usr/lib/libicucore.A.dylib Dock 155 daniel  txt REG   14,2   1580212   823126 /usr/lib/libobjc.A.dylib Dock 155 daniel  txt REG   14,2   2934184   823498 /usr/lib/libstdc++.6.0.4.dylib Dock 155 daniel  txt REG   14,2    132008   823505 /usr/lib/libgcc_s.1.dylib Dock 155 daniel  txt REG   14,2    212160   823214 /usr/lib/libauto.dylib -- snipped -- 

See what files and network connections a command is using with -c

lsof -c syslog-ng

COMMAND    PID USER   FD   TYPE     DEVICE    SIZE       NODE NAME syslog-ng 7547 root  cwd    DIR    3,3    4096   2 / syslog-ng 7547 root  rtd    DIR    3,3    4096   2 / syslog-ng 7547 root  txt    REG    3,3  113524  1064970 /usr/sbin/syslog-ng syslog-ng 7547 root  mem    REG    0,0   0 [heap]  syslog-ng 7547 root  mem    REG    3,3  105435   850412 /lib/libpthread-2.4.so syslog-ng 7547 root  mem    REG    3,3 1197180   850396 /lib/libc-2.4.so syslog-ng 7547 root  mem    REG    3,3   59868   850413 /lib/libresolv-2.4.so syslog-ng 7547 root  mem    REG    3,3   72784   850404 /lib/libnsl-2.4.so syslog-ng 7547 root  mem    REG    3,3   32040   850414 /lib/librt-2.4.so syslog-ng 7547 root  mem    REG    3,3  126163   850385 /lib/ld-2.4.so -- snipped -- 

Pointing to a file shows what's interacting with that file

lsof /var/log/messages

COMMAND    PID USER   FD   TYPE DEVICE   SIZE   NODE NAME syslog-ng 7547 root    4w   REG    3,3 217309 834024 /var/log/messages 

The -p switch lets you see what a given process ID has open, which is good for learning more about unknown processes

lsof -p 10075

-- snipped -- sshd    10068 root  mem    REG    3,3   34808 850407 /lib/libnss_files-2.4.so sshd    10068 root  mem    REG    3,3   34924 850409 /lib/libnss_nis-2.4.so sshd    10068 root  mem    REG    3,3   26596 850405 /lib/libnss_compat-2.4.so sshd    10068 root  mem    REG    3,3  200152 509940 /usr/lib/libssl.so.0.9.7 sshd    10068 root  mem    REG    3,3   46216 510014 /usr/lib/liblber-2.3 sshd    10068 root  mem    REG    3,3   59868 850413 /lib/libresolv-2.4.so sshd    10068 root  mem    REG    3,3 1197180 850396 /lib/libc-2.4.so sshd    10068 root  mem    REG    3,3   22168 850398 /lib/libcrypt-2.4.so sshd    10068 root  mem    REG    3,3   72784 850404 /lib/libnsl-2.4.so sshd    10068 root  mem    REG    3,3   70632 850417 /lib/libz.so.1.2.3 sshd    10068 root  mem    REG    3,3    9992 850416 /lib/libutil-2.4.so -- snipped -- 

The -t option returns just a PID

lsof -t -c Mail

350 

ps aux | grep Mail

daniel 350 0.0 1.5 405980 31452 ?? S  Mon07PM 2:50.28 /Applications/Mail.app 

Advanced Usage

Using-a allows you to combine search terms, so the query below says, "show me everything running as daniel connected to 1.1.1.1"

lsof -a -u daniel -i @1.1.1.1

bkdr   1893 daniel 3u  IPv6 3456 TCP 10.10.1.10:1234->1.1.1.1:31337 (ESTABLISHED) 

Using the -t and -c options together you can HUP processes

kill -HUP `lsof -t -c sshd`

You can also use the -t with -u to kill everything a user has open

kill -9 `lsof -t -u daniel`

lsof +L1 shows you all open files that have a link count less than 1, often indicative of a cracker trying to hide something

lsof +L1

(hopefully nothing)
