If
user use bash -c "" will easy to get unexpected result if user just
copy-paste working code from existing shell session into bash -c "" (OR
extend existing bash -c "") and expect it same. But if user use single
quotes(outermost) consistently, then user can get rid a lot of trouble.
Note:
If someone block you after unfriend, it still possible to see post by create new account which only added you, so there are still some possibility it will shows post of friend of you.
There are actually 2 privacy bugs here.
First bug is the search able to store deleted comment in plugins( and probably also apply to other places I don't noticed). The first bug shows the over powerful of search by post leads bug.
The second bug take further step of first bug which tick on filter by "Your Friends". This bug proved that the friend relationship never drop even after
unfriend, which actually also happen if the new account add only you and
unfriend you then the friend suggestion more likely is still your friends.
A look on the relationship between strace and netstat to diagnose network traffic.
I trying to download blog at https://linux-audit.com/ via python, but `requests.get()` keep stuck until timeout specified, but it able to get response data after timeout.
But curl is working, why?
After dig into strace socket/connect syscalls, I eventually realized that syscalls showing two critical familly, INET and INET6 which represents ipv4 and ipv6 respectively. But INET only run after INET6/timeout.
And I also noticed curl calls both syscalls at sequence without blocking, so it seems at least one is success is fine.
Anyway, I subscribed mobile network and it changed to ipv6 now, so I can't reproduce anymore ipv4 not working to call ipv6 address at the time of writing.
p/s: net-tools has been unmaintained for years, and so netstat was deprecated, and you should use `ss` as replacement . --inet/inet6 need replaced by -f inet/inet6 or simply -4/6, but I noticed can't use both -4/-6 same time except not put family options at all. Also need -H do not always shows header which can different width/position and creates unnecessary diff. And you might want `| column -t` piped from ss.
ss useful to include udp/icmp's ping traffic listed with ip which can't be done in netstat. But still the output columns too messy/wide to see in a glance.
