I run a webserver with centos 5 and like to change hardware. I run a 1u supermicro 6014t server with 4 *500gb raid 6 and like to downgrade to a smaler but more efficient server. The problem is this. I'dd like to transfer all the content and the whole OS to the new system, but how do I do that

I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.

I have a RHEL 5 system running vsftpd. If I do a put to the box, files larger than 1 GB fail around the 1 GB point. Smaller files don't have a problem. If I do a get from the box there is no problem. Both the FTP server and client are plugged into a Netgear switch. I'm trying to create an FTP server and web server so my friends and I can upload our vacation pictures. Ultimately I want my friends to be able to access my server. Right now I'm just trying to make it work between my two machines.

Actually the windows xp pc needs to restart before I can see the files, why is that? One more question, how can I transfer the profile directory from another CentOS box that will act as the storage of the roaming profile of the users? I use this in configuration smb.conf

I have a server with Private IP and without any public IP. I want to transfer files to the private IP. I can log in to the Private IP through SSH. So basically I installed vsftpd in the server with Public Ip and tried to ftp the public ip from the private ip but it is not working.
View 1 Replies View RelatedHere's the system:
1 server running regular Ubuntu, 40km above the surface of the earth on a scientific balloon behind an iridium modem (RUDICS) connected to its serial port
1 server on the ground running Ubuntu server
1 intermediate server used for contacting the iridium system from the ground server
I'm not sure if all the above details are completely necessary but I included them for completeness. I would like to be able to log into the balloon server and transfer files in both directions. The procedure for connecting is to telnet to the intermediate server and then to issue some modem commands to call the balloon. The balloon server is set with getty running on the serial port connected to the modem. The way I have figured out to transfer files is to run kermit on the ground server and connect to the balloon server through the intermediate server, then run kermit on the balloon server, and set it as a file server with the server command.
However, there is some sort of timeout or something, and only a few kB of any file gets transferred before the connection is broken. After that it seems like the ground server is trying to get the file from the intermediate server (which has no useful files on it at all). The file transfer screen stays open and it keeps trying and trying to transfer, until I type ^C. I don't know if there is a way of detecting through a kermit command whether the connection is still open or if there is some sort of switch to make the transfer automatically stop once it has stalled.
I have been reading about No Kermit Server (NKS) protocol, which seems to be designed for a system like this where the connection is across a third server. Is this likely to do a better job of keeping the connection open and the file transfer going? How can it be implemented? Is there any kermit command to determine from the ground server whether the connection is actually still open? Is there any way of telling whether the connection goes all the way to the balloon server or whether it ends at the intermediate server? I actually just learned about kermit today.
On a related note, is it possible to have the balloon server running getty on the serial port but still have the port accessible for reading and writing by, say, a python script (which could use the modem to dial down to the ground when it isn't in use)? It doesn't seem to work but I'm wondering if there is a way. Is there a way to temporarily stop getty, then restart it, or is this potentially hazardous? Keep in mind there will be no way to contact it if something goes wrong since it will be 40km above the earth.
I'm carrying out a project for my university (CIT in Cork, Ireland) and I'm using CentOS running over WMware. I have a server and a client. The server has no GUI (command line UI) while the client has a UI. I need to install a Simple Forum Machine application and I'm told to FTP the files into the server. I figured out that the best option is to load the files in the client via the GUI and then ftp them in the server. How do I transfer the files from a the client t o the server using FTP? I'm totally new to Linux so the more details the better. Also I'm trying to mount a USB key on the server but have had no luck.

I'm looking for a most possible, secure solution to transfer data using rsync over Internet between 2 linux server.

Which one in your opinion should be most secure solution?
I have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?

I have 2 computers on the same network that i need to link together to transfer files 1 is a web server the other is a minecraft server. the problem is that the file transfer will be constant as the minecraft server will constantly updates files on the web server and I dont want it to go to the router then to come back to the web server. I want to add a second network card to each computer and link them together and use this second connection to transfer the files is it possible?

View 3 Replies View RelatedI 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).
We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
The current list of NIS servers looks like this:

View 6 Replies View RelatedI'm working in a little company and 2 weeks ago one of our server had a hard disk failure (yes it was a seagate 11) and after passed two days without sleep trying to recover everything (and we did it!!) we took the decision now to use in some of our server a raid sw, so if one HD fail we can continue with our system without losing nothing. Yes I know normally you have to take all the precautions before so this things never happen, but you know I thing if it never arrives you, you always think than you're lucky and it's never going to happen to you but one day you discover reality.
So now this server is working with a Centos and the default HD partitions one boot partition and the LVM. I'm reading everything I'm finding about raid sw and lvm but I don't find if it's possible to create now with the system working a raid sw without having to reinstall all the system. Is it possible to do it ? If not what are my options to make a system backup before reinstalling everything?
