大型syslog文件

Question

我的syslog文件位于/var/log，今天大约有80 to，所以我清空它，几个小时后它已经增长到30 to，这就是日志文件一直在写的：

Sep 18 19:35:26 media-OptiPlex-3050 gnome-session[1243]: extern "Python": function Cryptography_rand_status() called, but @ffi.def_extern() was not called in the current subinterpreter.  Returning 0.

您的错误是python密码学与openSSL中臭名昭著的bug之间的不匹配。有一个解决办法，下载和强制更新两个版本匹配两者。

wget https://launchpad.net/ubuntu/+archive/primary/+files/python-cryptography_1.7.1-2_amd64.deb
wget https://launchpad.net/ubuntu/+archive/primary/+files/python-openssl_16.2.0-1_all.deb
sudo dpkg -i python-openssl_16.2.0-1_all.deb
sudo dpkg -i python-cryptography_1.7.1-2_amd64.deb

这个错误已经在新版本中解决了。
