Hi all,

This is a question to just enhance knowledge on Linux server administration.In dns we have some error checking commands like
named-checkzone and named-checkconf to check any syntax errors in server
like wise we have following command for different servers

vsftpd check for syntax error

Code:

 vsftpd

BIND DNS Server check for syntax and zone errors:

Code:

named-checkconf  
named-checkzone

SAMBA check config errors

Code:

testparm

APACHE check for syntax error:

Code:

 httpd -t

so my query is.. there will be some commands for the following servers too squid,sendmail,postfix,dovcot etc
please post if you know other commands which will be used for error checking of server config files.

Thanks,
Surendra.

It is really sad that iptables lacks syntax checking option, nice list though...
