Linux fail2ban not starting up after yum update on CentOS 5
This is the current issue:
[root@messaging ~]# service fail2ban status
Fail2ban (pid 30613) is running...
It just hangs there - have to hit Cntl-C to proceed.
How can I tell yum to downgrade fail2ban? I upgraded wth yum update fail2ban
How can I remove fail2ban and re-install?
Also how can I debug why its not starting up. It did fine before the yum update.
Some more info:
[root@messaging ~]# service fail2ban start
Have to hit Cntl-C to continue and shows an OK.
not ps -ax
for most modern linux systems.
2. yum downgrade packagename
this is how you downgrade to any other versions in your repository
You can also manually downgrade by using rpm.
3. It may also be helpful to install strace
yum install -y strace
then, instead of just using service you can try:
strace -e file /etc/init.d/fail2ban start
That will give you better debugging output.
