Server :: Scp/ssh To Cygwin Server From Server Without Password Prompt?
May 16, 2011
I've seen how to do this from native linux native server to linux native server. Not a problem. My question has to do with ssh/scp exchange of key exchange between a windows cygwin server and a linux server.There seems to be no /home/root/.. to hold the key exchange files. I've tried this between a cygwin server with a /home/administrator/..subdirectory and the /root subdirectory on the linux server. Is this how I should do this?Someone else set this up between these two servers earlier but forgot to document how it was done in his notes.I don't want to break the existing systems by setting up the key generation incorrectly on the functioning pair's of servers.
CentOS 5.4 Cygwin CYGWIN_NT-6.0-WOW64 1.7.5(0.225/5/3) I'm trying to setup password-less login from my CnetOS server to Win 2008 Server via ssh. I have followed the fab walk-through here and many others. When i try to connect I get this msg after a few seconds delay...
Code:
Connection closed by 10.8.0.6 When ran with ssh -vv...
The homes is suppose to let each user see his/her own home directory. But I tested at the windows side, I found that windows doesn't even prompt me about username or password, it just directly give me "not accessible" error. How do I config so my windows side at least prompt me about username/password?
Is it possible to somehow setup an ssh server that doesn't require a username,password or cert to login?I wish to provide shell access to a console program, which will prompt for a username and password.Encryption is essential though, and users must not be able to snoop in on each other
I am not seeing what i am doing wrong here, but here goes:
From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.
As an example, I have two servers, sm-i222 and fileserv. sm-i222 is a Win2k3 system running cygwin. fileserv is a linux box running RHEL 4.7. sm-i222 maps /cygdrive/c to the c: drive and /cygdrive/d maps to the d: drive(actually a single 4TB RAID). from the sm-i222 server /cygdrive/c I call a small script from the crontab. The internal IP for fileserv is 10.0.0.7. See below.
These three lines perform well in that they make a full transfer of the fileserv:/home/ directory on fileserv to the appropriate place on sm-i222 using rsync. I use rsync instead of scp because I have to traverse subdirectories and symbolic links in the /home/... filesystem on fileserv. What I'm looking to do is use rsync to do an incremental transfer/backup of only the files that have changed since the last full backup. I'll manage the times I do this manually or in crontab. A colleague says this is do-able, but not how. Rsync.org says this is do-able but not how. Cygwin says this is do-able... see rsync.org. I believe what I'm looking for is a single rsync line like I have above that only transfers the changed files on fileserv to sm-i222.
I'm running cygwin 1.7.7 on a win2k3R2 Standard edition server. I have a RHEL 4.7 linux host I'm scp'ing files from to the windows system using a simple cygwin scp command from what appears to be OpenSSH_5.5p1 on the cygwin host. When I run the simple scp command on the cygwin host, the counters initially display and increment/decrement, albeit what is at a much slower rate than is actually taking place. After the percent complete reaches a little less than 10%, all the counters from the cygwin console window cease to increment/decrement.
However, when I cd to the directory on the cygwin host where the file is being scp'ed to, the file is continuing to be transferred and a much higher rate than the counters seem to show. Finally, when the file transfer is complete by directly seeing the byte count as equal between the hosts, the scp counters will suddenly jump to 100% complete. This is not the case with my linux to linux scp's. The counters increment/decrement as expected and transfers are about what I'd expect over the same network infrastructure. This appears to be a cygwin ssh/scp implementation issue. I've posited this question to cygwin with no response as yet. The only reference I've been able to find on the 'net refers to buffering causing file transfers to appear to complete later than the transfer really does..........
I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
I have CentOS 5 configured with apache web server. but it is not asking for password authentication while accessing the web page. the config detail is as below code...
have to create a webhost on an running fedora server which runs multiple webpages + a coldfusion serveri have to add an coldfusion virtual host to these.what i would do:*crate a new user & group*enter vhosts.conf and copy an existing host and modify it for the new one.*create an new folder and copy the main files (phpstarter and webroot) *chown the files for the right useri think an apache graceful would be needet
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 ..
I'm running a linux cloud server with the following config 1.2ghz Processor allocation 752MB Ram
The site loads slow and clicking a link almost freezes the page for a second. Also, the page loads could be much faster. We've been running mysqltuner and have pretty much optimized all slow queries. Is there anything we can do to fine tune the server for faster and more responsive?
iam trying to sync file server data into backup server machine by command- rsync -avu path/of/data ipaddress-of-backup-server:/path/where/to/save after running it ask for root password and manually it is successful.but i want to make it automatic.for that i also tried cronjob and also generated authentication key but iam not successful in login automatically..anybody know how to authenticate root to login for storing data in backup server.
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 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 recently installed apache2 mysql php exc. to run a realtime stat site for my servers.the only thing is that the buttons/ images are not showing up.i checked that my GD was up to date and installed perl5 GD. dont know what else to check.my site with problems go to:http://24.20.177.228/stats_public
I am working on linux server with below specifications.Linux EDT 2008 i686 i686 i386 GNU/LinuxWhile checking the status of the server using the command 'opmnctl status' and when server is down the output is not getting redirected to file.I m using the command as,opmnctl status > abc.txt.
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)
We've set up a Red Hat Enterprise Linux 5 server and can log into it remotely just fine (with root and other users), but if I try to log in locally with a keyboard and monitor connected to the machine, I keep being returned to the login prompt. If a login is incorrect, I get an error message, but if it is correct then the screen just blanks and shows the login prompt again.While booting the only error message that comes up has to do with SNMPD, so I don't think it's related.
I read this post on the forum which seemed like a similar problem but it didn't help (I wasn't getting the "Module is unknown" message he was). I also read another post somewhere that said he was having the problem because the server was trying to use AD to authenticate, but I checked that and it's not the case with our server.From what I'm told (I didn't set up the server myself) it used to work fine, but then "something" happened one day that made it do this.
See, I am trying to run multiple website from, different IP. I have only one lan card. I have more IPS. I want to add many ips on same lan card from commnad prompt.
I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so
I'm trying to setup RAID 1 on a CentOS 5 server for a zimbra email server.I get a partion schema error. Can I do this?The server is a HP Proliant ML150 G3 server with two 80GB HDD.
