I have RHEL 5 joined to windows Domain and lately has been delaying in time like 20 - 30 mins off the domain controller. Any ideas why? It suddenly started this delays. I have to login and restart ntpd in order to sync and so users can login. Here is the output of ntpq -p:

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?)
we are synchronizing server time with ntpdate command in cron.how often should it run?
View 3 Replies View RelatedI'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.
#statsdir /var/log/ntpstats/

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?
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

View 2 Replies View RelatedI have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

/etc/init.d/ntpd - the NTP daemon
/etc/init.d/ntpdate - what is this ? and what is the relation between the 2 services?
I mean... if there is ntpd to do all the clock sync, what is ntpdate's role?

I'm trying to sync the clock of an ubuntu desktop with the network with ntpdate -u <ntp-server> and in a matter or minutes it's growing an offset of a few hundred milliseconds and even more than one second. Is there anyway to guarantee that the time keeps synchronizing with the network more frequently? does it make sense that the offset grows so fast? Am I doing something wrong?

Having some issues setting up sendmail on a (basically) blank RHEL 5.5 server setup. My ultimate goal is to be able to automagically send logs / errors / notifications to ourselves from the server.
Our basic setup is a Win 2003 domain with exchange running on mail.domain.com.au.
I've edited the '/etc/mail/sendmail.mc' and added the :
Code:
line to it.
Also added the domain (domain.com.au) to the '/etc/mail/local-host-names' files
Also edited submit.mc and added
Code:
When I try and send a mail from root or a test user to one of the domain accounts, it seems to go fine, i.e no errors are reported but it never gets delivered.
From the mail logs:
Code:
So it seems to be sent to the queue no problems and when I check the queue :
Code:
Total requests: 0
Not nothing ever gets received. Am I missing something? I have read and read and read but dont seem to be getting any furthur.
So in the end this server doesn't need to do anything except be able to send mail from root to an external mail address.
In oreder to run an application software on RHEL 3 ES server, I created a link forcefully using following command from root id:
# cd /lib64/tls/
# ln -sf libc-2.3.4.so libc.so.6
before that I copied file libc-2.3.4.so from a workstation with OS RHEL 4 WS so that a link can be created.
Now I am unable to run any command except cd & pwd and it gives error messaage as given below:
ls:relocation error:/lib64/tls/libc.so.6:symbol _rtld_global_ro,version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2with link time reference.
Before running this command libc.so.6 was pointing to libc-2.3.so file in path /lib64/libc-2.3.2.so.
I am now unable even to open a new window on the server.Please send me some solution as early as possible because this server is running production data and many users are runnig application on this server.
we are running a Red Hat Enterprise Linux ES release 3 (Taroon Upd 5) Kernel 2.4.21-32.ELsmp since several years. The server hosts an old ERP system who will be replaced at the end of the year.However it is necessary that some collegues are able to write some files to that server regulary. Since we are running Windows 7 on several machines, those users aren't anymore able to write to the samba share. Getting files from the share works fine.
But the problem seems not to be situated at the samba service because also the transfer using SSH (WINSCP) from any Win7 system to the server doesn't work.During testing we recogniced that transfering files smaller then 1kb works fine ... any file greater then 1kb ends up in an connection abort. This works with samba and also using SSH.All the workarounds editing some registry entries in Win7 for improving the interoperability between vista / win7 and samba don't work for us ... and also seem not to be the source of the problem.Is there a general known incompatibility between our RHEL version / kernel and Windows 7 regarding file transfers?
I have a RHEL 5 server with 32 bit architechture that is not recognizing more that 4 GB of RAM and I am trying to locate a version of the kernel-PAE package that will work well with the 2.6.18-53 kernel. I found something on Open VZ called ovzkernel-PAE that is built for the 2.6.18-53 kernel [URL]
and wanted to find out if there were any known issues with this release before I attempted to install it. Is anyone aware of any issues with any rpms on openvz.org or with this particular rpm in general?
I have a RedHat box that I have configured, security, audit rules, latest updates, etc. I want to be able to "image" that configuration so I can kick other boxes with that "image", that way no other configuration/updating needs to be done on the newly kicked boxes. What is the best way to accomplish this? To make things more difficult, it would be near to impossible for me to pull any software off the internet for this.
View 5 Replies View RelatedI am trying to look at installing the PAE module on a RHEL 5 2.6.18-53 system and I cannot seem to find that around. I had hoped to find out if installing the CentOS 5 2.6.18-128 or 2.6.18-164 kernel-PAE modules would have a lot of negative consequences? Perhaps one of you could direct me to a download site that would provide kernel-PAE for a 2.6.18-53 build?
View 4 Replies View RelatedI have seen and tried a lot of web information about issues with VNC and the RHEL 5.x implementation of VNC.
I can't seem to get the behavior I want. Let me explain.
With SLES 10, I can use YaST and with a few clicks end up with a system that when rebooted, accepts VNC viewer connections to :1 and displays the system login screen.
Here I can log in as root or any user. Once logged in, I can choose to use the command line to restart the system if necessary and eventually, I can reconnect with the vncviewer to the system login screen.
RHEL 5.2 has a "share your desktop" setting in preferences which works fine, but requires that I be logged in locally, which prevents remote restarts. There is also a system services dialog that refuses to start vncserver as a service. There are numerous tutorial in the RH knowledge base and the web that explain how to specifically setup individual displays, :1, :2 for specific users and claim that it can work after boot. I have not been able to get these working, but what I really want is a simpler, single display, :1, that will present the RHEL login screen so I can log in as any user I want. I am the only person accessing these servers and they are behind a firewall using secure protocols when remote.
I think Red Hat did not want to make this too easy as VNC users need to consider the security risks. Is there a way to get the SLES 10 VNC approach to work on RHEL 5?
