Eslam's questions

I'm trying to change password for a NIS account from a Centos-7.0.1406 client and the server is Centos-6.6

it seems that passwd command don't ask me neither to change password nor ask me for old password, it only returns the following

Changing password for user mashour.

passwd: Authentication token manipulation error

here is also strace snapshot

open("/usr/share/locale/en_US.UTF-8/LC_MESSAGES/Linux-PAM.mo", O_RDONLY) = 5

fstat(5, {st_mode=S_IFREG|0644, st_size=520, ...}) = 0

mmap(NULL, 520, PROT_READ, MAP_PRIVATE, 5, 0) = 0x7fa11e121000 close(5) = 0

+++ exited with 1 +++

However I can change the NIS account password from any Centos-6 client using passwd command.

Any ideas what's going wrong ?

I have a problem with keytool tool.

I have a FishEye/Crucible server which needed to be connected to my Jira server. My Jira server uses SSL. I'm trying to import ssl certificate using the following command:

 keytool -importcert -alias "JiraCert" -file jira.crt -keystore $JAVA_HOME/jre/lib/security/cacerts
Enter keystore password:  
Keystore password is too short - must be at least 6 characters
Enter keystore password:  
Keystore password is too short - must be at least 6 characters
Enter keystore password:  
Keystore password is too short - must be at least 6 characters
Too many failures - try later

but it asks for password which is empty one as I managed to list available certificates in that keystore with no password, just Enter is pressed.

What do you think, what shall I do?

i'm wondering if i can create a Security Group that limits access of internal network , as i know all ports are open for internal network and i wanna limit it

What tool do you use to monitor your servers?

I'm searching for a monitoring system that has the following features:

1. targeted for Amazon EC2
2. scalable
3. custom plug-ins can be added, prefer python
4. installation and configuration can be automated
5. integration capability with other monitoring, log systems
6. output graphs are clear enough to make right decisions

I searched alot and I found lots of tools such as:

• god
• zenoss
• nagios
• munin
• cacti

but I can't make decision which one is the best and has all of these features and more.
