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
driftfile /var/lib/ntp/ntp.drift
# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

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

I configured openLdap in RHEL5 on virtual achines,everything is working fine, I created a user called ldapuser,in LDAP server and i created a home directory for ldapuser in my LDAP client, now i can able to login to the both Server and client with ldapuser account....

I am trying to synchronize the time of my VM server with ntpd. I have the following configuration. And in the /etc/ntp.conf, I have the following line:
restrict default ignore
restrict 127.0.0.1.
server time1.server
server time2.server
Whenever I have this line, the erver is not able to synchronize its time... So far as I understood, this line prevents other servers using this machine as a time server. And the second line says to allow localhost to use as time server. But why do I need to use its own time server when I have specified to use time1.server and time2.server ? ( firewall for tcp and udp ports 123 is open)
However, when I replace the first line of the configuration with the following line, it works. restrict default kod nomodify notrap noquery But with this, i am allowing other servers to use this server a ntp (which I wouldn't like to). Why this machine tries to use ntp server of its own (to snyc time) and why it is not working though i have the entry "restrict 127.0.0.1" ??
I have installed the synckolab add-on in thunderbird to synchronize with my citadel server. The calendar and tasks in te server are synchronized to my client, but not the other way round, i.e. the changes in thunderbird are not written to citadel. Contacts get synchronized ok, in both directions.
Setup is:

Due to recent releases of Ubuntu/Kubuntu/Mint/Mint KDE, I'm pretty near ready to take the plunge full time into Linux on my main desktop machine. Just one thing stopping me though at the moment... folder synchronization.
I have the following setup:
1) Desktop machine running Mint KDE or Gnome hard wired to a Netgear DG834GT router.
2) Archived files stored on a dedicated partition mounted as /home/lucas/archive.
3) Laptop running Windows 7 also hard wired to the router.
4) Shared folder on the Windows 7 laptop called "Archive" on a dedicated "Data" partition.
What I would like to do is synchronize the folder specified in 2 above to the shared folder specified in 4 above.
In Windows I use SyncBackPro to synchronize folders. Is there anything similar in Linux?

I briefly was able to share a folder in my Windows machine, and access it through my Ubuntu machine, after connecting both laptops with a cross-over cable. However, I can't even ping the Windows machine from my Ubuntu machine anymore, after trying to configure the IP addresses. I think I screwed it up.
Also, although this is not an Ubuntu issue, I have a weird Windows problem, where I can't access the Internet when both wireless and wired ethernet controllers are active at the same time. It would be a bonus if you could solve this problem too for me. I was surfing online for a solution to this problem for quite some time, but I was unable to comprehensively understand and implement what I browsed through. Also, some of the guides, like for example, that on configuring Samba, seem to be outdated, as the terminal tells me something like the package (that was required to be installed by the guides through sudo apt-get install) has been superceded. Hence I post here for clear, concise and easy-to-understand help from you gurus. It would be great if I could achieve the end result of being able to access the internet on my Ubuntu machine (through the Windows one).

I have an Ubuntu server that is currently running Ubuntu 8.10. I was thinking of making it a VPN server for my iPhone and also for my laptop whenever I'm outside and need to access internet over insecure wireless networks. Now that part should be easy I found several guides on how to configure OpenVPN server, as well as enabling clients on iPhone, and OSX.
However, the things is that my server is currently a OpenVPN client also, I have a paid tunnel set up to bypass my ISP blocking incoming traffic on various ports. Is it possible to keep this setting but still enabling a VPN server? Essentially causing traffic from my external device to go in through my tunnel to the VPN server, and then out through the external VPN provider.
I'm currently successfully using the Terminal Server Client to connect to an SBS 2003 server at a remote location. I've been trying to figure out if it's possible to connect to any of the XP machines on the LAN behind it. I currently have to use RWW in IE on a VirtualBox XP machine to do that, and I'd love to be able to get rid of VirtualBox completely.
The server has 2 NICs, one connected to the internet, and the other connected to the LAN. There is only one public IP. The computer I'd most like to connect to has a static, private IP. Anybody done anything like this or have any thoughts on how to get it to work?

View 1 Replies View RelatedI have about 5 computers on my network that get their internet connection from a Linux NAT server.
192.168.12.02 is a Linux server that has a NAT set up to share the internet connection.
192.168.12.03 is a download server that is almost always downloading
192.168.12.05 - 192.168.12.20 is assigned by DHCP to users.
I want to make it so that the download server runs at full speed but is throttled only when someone from the user IP addresses range tries to use the NAT server.I think I'm looking for some way to set the download server's packets to have a lower priority than the client's packets. Is there a way to set this in the Linux server?
Was trying to understand the behavior of TCP when the server becomes unreachable . For this I am using vsftpd and the default linux ftp client to check the behavior.I was trying the following things. Was Trying to download a file from an FTP server using the FTP client as anonymous user. While the file is getting downloaded, I removed the network cable from the FTP server to understand the behavior of TCP when the server becomes unreachable.
As per the functionality of TCP/IP , when the server becomes unreachable for whatever reason , the client tries retransmitting the data till it can send the data or it timeouts. But in my above experiment using FTP , I can see that the FTP client is not trying to retransmit data at all . This I came to know using by sniffing FTP traffic at the client side. Is this expected or default FTP client available in Linux does not obey TCP/IP functionality properly ?

View 2 Replies View RelatedThe server is named alpha and is running Archlinux. It is exporting a directory named /files. The server is a couple of years old and I have accessed it extensively from clients running Arch, Suse, PCLinuxOS, and maybe some others, all with no problems. The clients (3 of them) are new installations of Linux Mint 10 (Julia). When I mount the nfs all of the nfs files are visible as expected. However, the owner/group is drastically different than on the server.
I might add that I have set up user id's and group id's the same. My user is 1003 on all systems, and the users group is 100 on all systems. When I am on alpha (via ssh), here is a partial file listing.
