[CentOS] Dovecot Port 993 and 995 not connecting.
Hello Mates, I am facing a really weird issue with my mail server, somehow I cannot connect using port 993. It works with 143 but not 993 nor 995. Here is a little bit of more information: # telnet localhost 143 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot ready. --- ]# telnet localhost 993 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1...

Re: [CentOS] Bind isn't working. after upgrade.
Ok, Here is the update: I deleted the line: ROOTDIR="/var/named/chroot" on /etc/sysconfig/named restarted named and now, it shows me: WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf) rndc: connection to remote host closed This may indicate that * the remote server is using an older version of the command protocol, * this host is not authorized to connect, * the clocks are not synchronized, or * the key is invalid. named (pid 3442) is running.. but, after this, the Nameservers and DNS are working and solving. Anything to fix those awful messages? -- Carlos Sura.- www.carlossura.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yes, port 53 is listening on configuration and with netstat -atpn | grep -E ":953|:53" it shows named.

[CentOS] Bind isn't working. after upgrade.
Hello Mates, I just reciently updated BIND on my CentOS 6.2 (don't remember which version) but now I am using version: BIND version 9.8.2 The packages I have: bind bind-libs bind-chroot bind-utils bind-devel First of all, doing "service named status" it throws me: WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf) rndc: connection to remote host closed This may indicate that * the remote server is using an older version of the command protocol, * this host is not authorized to connect, * the clocks are not synchronized, or * the key is invalid. After a Google search I found: to remove rdnc.key and it was suppose to be working ok. and I chown named:named the file /etc/named.conf, now if I do "service named status" it throws me: version: 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.1 CPUs found: 4 worker threads: 4 number of zones: 17 debug level: 0 xfers running: 0 xfers deferred: 0 soa queries in progress: 0 query logging is OFF recursive clients: 0/0/1000 tcp clients: 0/100 server is up and running named (pid 1456) is running... The thing is, whenever I want to check the domain name on intoDNS.com service it says: ERROR: One or more of your nameservers did not respond: The ones that did not respond are: and it show boths are bad, I thought may be a delay on propagate, but now I have 2 hours waiting and still nothing. Any help?
