Question My server is having unusually high CPU usage, and I can see Apache is using way too much memory. I have a feeling, I'm being DOS'd by a single IP - maybe you can help me find the attacker? I've used the following line, to find the 10 most "active" IPs: cat access.log | awk '{print $1}' |sort |uniq -c |sort -n |tail The top 5 IPs have about 200 times as many requests to the server, as the "…

Question Is there anything in Python or Linux what basically instructs the system to "install whatever is necessary". Basically I find it annoying to install python packages for each new script/system/server that I work on. Each time I end up doing a sudo pip or an apt-get or dnf anyway. Why not automate that within the script itself. Wherever a 'no package found' error crops up, pass the library name to the install statement.…

Question I am building a C++ executable on Linux. The executable links into some boost libraries. This is the output when I attempt to run the binary: root@yourbox:~/work/dev/c++/projects/testfgci/dist/Debug/GNU-Linux-x86$ ./testfgci ./testfgci: error while loading shared libraries: libboost_system.so.1.45.0: cannot open shared object file: No such file or directory I then run ldd on the binary to check dependencies: root@yourbox:~/work/dev/c++/projects/testfgci/dist/Debug/GNU-Linux-x86$ ldd testfgci linux-gate.so.1 => (0x00380000) libboost_system.so.1.45.0 => not found libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00b50000) libm.…

Question I have another thread asking help on "missing zlib". With the nice help the problem has been resolved (almost). Now I am interested in building Python myself (on Ubuntu 10.10). A few important questions have caught my attention: After building Python (say 2.7.1), do I need to rebuild Python if I have missing modules? Is there a way to find out what modules will be missing prior to building Python?…
