If I had the luxury of time, I would have put it on a spare machine and written some docos myself, and that may happen yet, but not right now. Just an FYI. VHCS was forked a little while ago and you will find it at isp-control.net. ispCP has a few of the 'bugs' fixed and is moving at a faster rate than VHCS is. I used vhcs to host about 200 domains for a couple of years and didn't have any massive problems but like any control panel there was a few short falls. With a little massaging it was a nice system. Much nicer than the commercial ones and less bloat for the customers to 'fiddle' with. If you do decide to install VHCS or it's fork feel free to fire of a question or two if you get stuck on anything. In the end, I opted for vsftpd in a chrooted environment.

It currently is running Mandriva Server 3 which is getting old and I am in the throws of setting up a new server using Centos 5.2. Most of the web based stuff that I serve is based on Joomla but one customer has had a professional web designer create a new site for him which I have uploaded and all is working just fine. I have never allowed FTP, SFTP nor SSH access to the server for security reasons (other than myself) but this customer wants to directly edit his new web site from time to time. I don't run C Panel (can't afford it) nor can I run ISPConfig which has some features missing such as mailing lists which a couple of clubs I host use. I am looking for suggestions as to what members might think would be an easy but secure way for this customer to do what he wants to do - make changes to his web site directly on the server. I run name based virtual domains and I guess I could set all other folders which other customers use with chmod 700 and perhaps set up his folder as 750 and make his username part of the apache group. I would then make his home area his web page folder but I am looking for a better way - if there is one. Would webdav be the ticket although I have never successfully set this up or is it just as easy for him to use an FTP client using SFTP to access his web root and make changes? Webdav (with https for security ) could help you here but with chroot capabilities in openssh you could allow the user in via ssh or sftp and chroot them to their $HOME.

Re: [SLUG] restricting ssh private key to access sftp only
Hi, On Mon, 14 Apr 2008 12:18:06 +1000 Amos Shapira [EMAIL PROTECTED] wrote: Hello, I'm setting up a script which uses sftp to manipulate remote files through ssh. I created a private/public key pair for it without a pass phrase on it, installed the public key on the remote server and now I can use both ssh and sftp to login to it. I'd like to restrict this key to be able to use only sftp and nothing else. According to man sshd, the command option should do that: command=command Specifies that the command is executed whenever this key is used for authentication. ...Note that this option applies to shell, command or subsystem execution. So I added a command=sftp to that key's line but this causes the entire session to abort. When I remove the command part I can use sftp and ssh again. http://troy.jdmz.net/rsync/index.html has an example. from=10.1.1.1,command=/home/remoteuser/cron/validate-rsync ssh-dss B3Nza C1kc3MAAAEBAKYJenaYvMG3nHwWxKwlWLjHb77CT2hXwmC8Ap+fG8wjlaY/9t4uA+2qx9JNorgdrWKhH SKHokFFlWRj+qk3q+lGHS+hsXuvta44W0yD0y0sW62wrEVegz+JVmntxeYc0nDz5tVGfZe6ydlgomzj1 bhfdpYe+BAwop8L+EMqKLS4iSacNjoPlHsmqHMnbibn3tBqJEq2QJjEPaiYj1iP5IaCuYBhuTKQGa+oy H3mXEif5CKdsIKBj46B0tCy0/GC7oWcUN92QdLrUyTeRJZsTWsxKpRbMliD2pBh4oyX/aXEf8+HZBrO5 vQjDBCfTFQA+35Xrd3eTVEjkGkncI0SAeUVAMZSASmQ9Pi38mdm6oiVXD55Kk2rAAABAE/bA402V SNIP -- Regards Mick Pollard ( lunix ) BOFH Excuse of the day: Non-Static Checksum Dereferencing pgpzCi5UD97zO.pgp Description: PGP signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Network Real-Time Hot Filesystem Replication?

What I'm looking for is a way to do real-time hot-replication of a whole filesystem or filesystem tree over 2 nodes (and strictly 2 nodes) without STOMITH[1]. The scenario is I have two identical systems with local (software) RAID1. They will be tethered onto their internet feed via ethernet, and can optionally be tethered to each other via Gig. Have you had a look at http://www.drbd.org/ ? It basically mirrors a blockdevice over ethernet.

A member of our lug just recently got a new mobo and it has a Realtek ethernet port onboard. It doesn't work out of the box with either Ubuntu or Centos. I believe he has found a 3rd party module he had to compile and insert into the kernel.
