sockets - How can I monitor network connections by maven and childs? -


we have maven project runs several integration tests. of tests involve spawning child processes hsqldb database, of maven plugins might opening socket connections places i'm not aware of. provokes when running tests in jailed environment of continuous integration server, lot's of logs of failed connections appears while in local machine goes smoothly.

how trace connections given maven script , childs opens?

see https://unix.stackexchange.com/questions/30046/logging-outgoing-connections-as-they-happen answers how trace network connections process.

but in case of maven, connections check status of snapshot dependencies.

to fix those, should set maven proxy (like nexus) in network , tell maven resolve dependencies via said proxy. should reduce external connectivity 0.

also mvn -x (enable debug mode) should help. write output log file , grep http:.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
