What is the right way to keep updated the time on a server? Using ntpd daemon or ntpdate by crontab? I've two server in two different locations.. I've used
Quote: # ntpdate ntp1.ien.it
on both server, and the two times were staggered by ten minutes. How is it possible?
we are synchronizing server time with ntpdate command in cron.how often should it run?

I wonder is the * means that its syncing with itself? if yes how to make it to sync with my remote server dc1 (2nd line?)
I'm trying to synchronize a client with an ntpdate server. The ntp.conf file from the server has the following lines: # /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for

# Enable this if you want statistics to be logged.

I can't update my ubuntu clock with my server. If i run the command ntpdate domain.local, it gives me this erro (no server suitable for synchronization found) if i run the command nslookup domain.local it works well and found my server

2. before upgrade what are the things i need to do??
3. is there any possibles the working function not working in new upgrade packages??
I have a set of machines on a disconnected network. Periodically, one of the machines connects to the internet and synchronizes its time with a time server that is not known until the connection is established. (The machine queries a central command server for the address of the time server it should synchronize to.)
I then use a custom tool to do some calculations to call adjtimex() and adjust the clock so that it runs fairly accurately.
I know ntpd is supposed to be able to handle disconnected networks but I thought you had to preconfigure the servers in the configuration file.
My intent is to run ntpd on this machine (without configured "server"s) so that it can serve time to the internal network. (Periodic synchronization using ntpdate from the internal machine to the bridge machine.)
The problem: ntpd wants to fuss with the values I set using adjtimex(). I want it to quit thinking it needs to adjust the clock and just serve time to the internal network. (Maybe I have a GPS time source hooked directly to the machine!)
I have been able to find enough information that I need to enable 'time-udp' in /etc/xinetd.d/ But there isn't an entry for time-udp. How do I enable time-udp (Time of Day server) on a Red Hat system? It's RHEL 5.6 64bit.

View 3 Replies View RelatedI have somewhere between 8 and 12 servers, spread amongst different webhosts, all running CentOS 5.3. Everything on the servers has been compiled from source:
> EngineX, PHP, MySQL, Munin, etc
I compile from source because I usually run ./configure to modify the source before installing. What would be the easiest way to keep the server software updated? I am considering creating custom packages from a server which I would keep up to date manually. Then use Capistrano or Puppet to install those packages on all of my servers.
my /var/log/secure file is not getting updated with ssh logins from yesterday.Even the login from my own ip is not updated.

View 1 Replies View RelatedI have been having trouble figuring this out. I have a machine running CentOS 5 and I want to setup an SMTP server behind a router on a home broadband connection. I've read many guides but nothing too specific as to what I need to do. I want to use either sendmail or postfix, but I don't know if I should purchase an SMTP relay. If anyone could point me in the right direction it would be great. I also have bought a domain name that I want to use, but I just cant put all these pieces together as of right now.
View 5 Replies View RelatedI have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.

The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.

View 3 Replies View RelatedI have configured master and slave Bind servers. Everything works fine. But whenever I add a new zone entry at master server it is not getting updated at slave server in logs I see this error:
client 192.168.1.1#43428: view external: received notify for zone 'yourdomainname.com': not authoritative
At master server I do not see any error or warning message. This error clearly indicates that named.conf file does not have zone entry in it or domain name is wrong. While checking the named.conf file I see that the zone entry has not been updated at slave server. If I update it manually and reload named on slave then zone files (db files) are getting created without any issue and any modification at master server for the zone records are also getting updated. My concern is why zone record is not getting appended at slave server in named.conf file.
Is there anything I am missing in the configuration. I am pasting the steps which I have followed to configure my master and slave server:
Configure Bind as master and slave server
Install Bind on your server
yum install bind
OR
sudu apt-get install bind9
Generate RNDC Key using the command
rndc-confgen -a -k rndc-key
it will stored in /etc/rndc-key file
Master Server IP 192.168.0.1
Slave Server IP 192.168.1.1

View 4 Replies View Relatedwe're about to migrate a set of workstations (ubuntu 10.04 LTS) to a new kerberos/LDAP setup. Basically, this requires the installation of some required deb packages and to copy some new .conf files over the original ones.We made a deb package having these "features":requires the needed other packages as dependenciesbacks up original conf filescopies the new conf files to the right places (i.e. /etc/krb5.conf,/etc/ldap.conf)The problem is: apt-get complains because the deb is "touching" files owned by other packages (kerberos, ldap, etc.). Therefore, the only way to skip this check is either to force apt-get to proceed or using the "replaces" directive in the deb control file, specifying the clashing packages. omething like this:

I have installed CentOS 5.3 with Xen on a PowerEdge 2650 machine with 6GB of RAM. As usual, PAE was already enabled so I did not have any problem with utilising all of the memory. However after upgrading to the latest release of the kernel (2.6.18-128.7.1.el5xen), memory available decreased to 4GBs. Then I switched back to the old kernel and 6GB was there. Then finally have switched back to the new kernel and 6GB is again there. So now PAE seems to be enabled but what concerns me is the inconsistent behaviour. (Also I am not sure the reason was the upgraded kernel.)

I am running Slackware64-current(multi-lib) and I have stumbled across something that I don't fully understand.I have read that the kernel-headers should not be updated as glibc is compiled against them and therefore requires that set of kernel headers. Recently the kernel version has been bumped a couple of times but glibc has stayed the same.Should glibc be re-compiled each time there is a kernel update?
Perhaps someone can explain, in very simple terms, the relationship between the kernel, the kernel headers, the kernel modules and glibc.
Do you have to reinstall Nvidea and Broadcom drivers every time the kernel is updated? The new kernel would not even load to where I could get to my desktop. Help?? I could not even sign in with older kernels. Had to use a Puppy CD to edit my Grub menu.lst so I could sign in on the older kernel.
