30 Ott 15 How to check SSL/TLS protocol for a given server
If you need to check which SSL/TLS protocol version is implemented by your webserver, you can issue the following command:
dino@dam2knb:~$ echo | openssl s_client -connect 10.38.46.137:8443 2>&1 | grep Protocol
Protocol : TLSv1.2
30 Set 15 apache [error] (13)Permission denied: Cannot create SSLMutex
On one of the servers of one of my clients, a Solaris 5.8 sparc host, apache did not want to start.
It wrote the following error message on the error_log file:
cojo1@myserver $ cat error_log
[Wed Sep 30 12:24:11 2015] [error] (13)Permission denied: Cannot create SSLMutex
The problem, in my case, was about the permissions on /tmp.
Since these machines can be accessed by hundred people, someone thought well to change /tmp permissions to 0775. Everybody knows that if whould be 1777 instead.
The lack of both the sticky bit and write permissions to other did not make apache starting for non root users.
Hope this help someone.
Ciao, Dino.
08 Set 11 orientdb.sh: line 52: return: can only `return’ from a function or sourced script
If you are using the powerful orientdb engine on linux/unix you may catch the following error when executing bin/orientdb.sh:
./orientdb.sh: line 52: return: can only `return’ from a function or sourced script
This is because of bash that does not permit the use of “return” from the main script body.
I prepared (and published to the orientdb list) a small patch that you can use if you don’t want to recompile the entire orientdb engine to solve this simple problem.
The problem it’s solved in SVN revision 3804 or greater.
