Server :: Configure RedHat As A Time Of Day Server For A Docsis Modem System
May 13, 2011
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.
I am new to redhat and tried to run my reliance net connect highspeed 1x... is there any possible way of directly using by pluging in... One way is using wine then running the exe format of the driver....but it too need net connection for further packages needed by wine...At present I have only usb modem for internet
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
I am planning to configure RedHat cluster on vmware, i dont know how to configure, i googled a lot but couldn't find satisfactory docs for configuring, can any one provide me step-by-step or good docs to go ahead.
I am trying to configure redhat cluster first time but no idea how to do it. I am using rhel 5.2. I have copied cluster rpms from redhat media and tried to install them but facing alot of dependencies problem. Can some one please guide how can i do redhat clustering from start. I am doing this for configuring single node clustering for zimbra suite but it is the requirement to configure redhat cluster first. One more thing i am using two virtual machines installed by using virtual box.
Right now i have a HP DL 180 Server with 130 Gb Hard Disk & 8 Gb ram after Raiding0+1. i want to configure Domain Controller Server for my office for 200 to 300 Users. what should the partition size must be mentioned in my 130 Gb Hard Disk, is that going to be Sufficient for ME ?
i am bit confused about /Usr /Var /Boot partitions, as i need to manage perfectly in 130 GB
if i go with 4 Gb swap and remaining for " / " is that will be fine ? should i need to specify partition sizes separately for / tmp /var / usr ..
logging in a server through putty in the same network when i executed last command its showing system ip logged in time and logged out time the output as followsthis is my system oot pts1 xx.xx.xx day month date time in time out timeand similarly am geeting other than this likeroot :0day month date time still logged in this is from more than 3 days its logged in
On installation of my OEL (Oracle Enterprise Linux), I've made a mistake, and set the date and time wrong. It's pointing to a date far in the future. So I change the date (and time), all looks OK. But when I boot, all is back to the same date (in 2015). I'm running this OS in VMware, I don't know if this issue relates to VM or not.
I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?
i have been trying to complete the following project1) Configure a FTP server where we can upload and download files.........2) server must run at 9 pm & stop at 9 am automatically ............although the first task was easy ,i have no idea how to accomplish the 2nd task(not to mention I'm a new user)
I'm trying to rsync files and directories from a RedHat linux host(v 4.5 & 4.7) to a Windows server 2003R2 Standard Edition with cygwin running. I'm executing the rsync command from the cygwin shell. The transfer involves rsync'ing approximately 1 TB of data from the linux server to the windows server. After about 280+GB of data transfer, the transfer just dies.
There seems to be no particular file or directory that the transfer stops at. I'm able to rsync GB's of data from other linux hosts to this cygwin server with no problem. Files and directories rsync fine.The network infrastructure is essentially the same regardless of the server being rsync'ed in that it is GB Ethernet running through Cisco GB switches. There appear to be no glitches or hiccups across the network path.
I've asked the folks at rsync.samba.org if they know of any problems or issues. Their response has been neutral in that if the version of rsync that cygwin has ported is within standards then there is no rsync reason this problem should happen.I've asked the cygwin support site if they know of any issues and they have yet to reply. So, my question is whether the version of rsync that is ported to cygwin is standard. If so, is there any reason cygwin & rsync keep failing like this?
I've asked the local rsync on linux guru's and they can't see any reason this should fail from a linux perspective. Apparently I am our company cygwin knowledge base by default.

I'm writing a phone app for Android that connects to a bluetooth RFCOMM device in my car. My phone app talks AT commands with it. For development work, I often need to communicate with the device to try different commands and things.
My neighbors are starting to think I'm weird because I sit in my car for hours on end with my laptop screen shining on my face, typing away like a script kiddie.
I'd much rather configure one of my many Linux servers to act as a bluetooth RFCOMM device and allow me to connect to it (indoors, while I sit on my couch).
I imagine I have to start with something like sdptool add SP
But then what?
I'm perfectly happy writing a perl app to handle the I/O, but I just don't know how to make the bluez stack accept connections and subsequently pipe that stream to a perl app.
I have installed the Apache, PHP and MYSQL in the rackspace cloud server environment. Can anyone please guide me How can I configure email server in that with postfix or some other with multiple domain.
