lsof problem

[linuxmac09]

I'm sorry if I put this in the wrong thread. I am trying to use lsof on my ipad and ipod touch however I get the following error every time I try to run it.

lsof: PID 3206 information error: Cannot allocate memory
lsof: PID 3203 information error: Cannot allocate memory
lsof: PID 3202 information error: Cannot allocate memory
lsof: PID 3201 information error: Cannot allocate memory

lsof: PID 14 information error: Cannot allocate memory
lsof: PID 13 information error: Cannot allocate memory
lsof: PID 12 information error: Cannot allocate memory
lsof: PID 1 information error: Cannot allocate memory

can anyone tell me how to make lsof work? thanks in advance

I'm getting exactly the same problem.

I tried restarting the device to attempt to free as much memory as possible for the lsof command, but no luck. I'm issuing the command via SSH from my laptop over wifi. This is on an old iPhone 3G running iOS 4.0.1

I tired it again on my iPhone 4 running iOS 4.0.1 with 300 MB free memory directly from MobileTerminal (426). Same deal.

Anyone have any idea what lsof is complaining about? I'm using lsof to try to figure out where the "No Service" icon is stored in the file structure so that I can change it -- this 3G will just be an iPod Touch for my brother from now on.

Thanks.

I'm trying to run lsof too and having the exact same problem.

I am using iOS 4.2.1 on an iPhone 4.

I am getting the same error:

lsof: PID 39 information error: Cannot allocate memory
lsof: PID 35 information error: Cannot allocate memory
lsof: PID 31 information error: Cannot allocate memory
lsof: PID 28 information error: Cannot allocate memory
lsof: PID 19 information error: Cannot allocate memory
lsof: PID 17 information error: Cannot allocate memory
lsof: PID 15 information error: Cannot allocate memory
lsof: PID 14 information error: Cannot allocate memory
lsof: PID 13 information error: Cannot allocate memory
lsof: PID 12 information error: Cannot allocate memory
lsof: PID 1 information error: Cannot allocate memory

Anyone know where I can get more assistance in getting this command to work? I have tried compiling it myself without much luck.

[santacruzlocal]

lsof should be located in /usr/sbin Try navigating to that directory and see what the permissions are set to.

Good Luck !!!

You can try this new lsof build for iphone 4 & iOS 4.2.1

http://pupil.io8.org/pub/iphone/misc...of-arm7-iOS4.2

Good Luck !!!

(Removed) Guy knows what he is talking about.

It's built by myself.

You can download iOS SDK from apple, and download
lastest lsof source code, build it by yourself.

There is a small trick, you need copy some include file
from iOS simulator SDK to iPhoneOS SDK.

What is that file? I don't think I should trust it from a user with 1 post.

[Oen386]

ROFL, sorry won't lie thought it was a trick.

Thanks for the response!

I will see if I can get it to work. Do you remember what files exactly?

I've been trying this. Can you elaborate on the 'trick'? I've compiled okay (with warnings), but when linking, I get:

Undefined symbols for architecture armv7:
  "_process_dev_stat", referenced from:
      _ck_file_arg in arg.o
      _enter_dir in arg.o
  "_write$UNIX2003", referenced from:

  "_stat$INODE64", referenced from:

      _dostat in misc.o

      _print_fflags in proc.o
   
 [... etc]

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I got this from elsewhere, so there is extra crap contained, but this is my link command:

clang -arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk -L lib -L /usr/lib -L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/usr/lib -L /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1\ \(9B176\)/Symbols/usr/lib -filelist linklist -dead_strip -miphoneos-version-min=5.1 -framework SystemConfiguration -framework UIKit -framework Foundation -framework CoreGraphics -o mylsofx

Also... When I try your compiled binary on my iPhone4 running 5.1.1, I only get:

Killed: 9

Update: This is related to code signing. I used ldid and the binary works great!


Any pointers on compiling would be appreciated, thanks...

How were you able to ldid that binary? When I downloaded it and put it in /usr/sbin and updated permissions I got util/ldid.cpp(660): _assert(78:signature != NULL)

You used the binary from here right? http://pupil.io8.org/pub/iphone/misc...of-arm7-iOS4.2
I'm also on iOS 5.1.1

[Rireal]

Does anyone have an update on this? The binary above gives me a Killed: 9 error and I have been unable to compile from source successfully. Any help would be much appreciated.
