  1. [ubuntu] Re: Unable to install postfix atal: open database /etc/aliases.db: Permission denied

    I settled on the latter workaround. I edited /var/lib/dpkg/info/postfix.postinst to comment out the line that removed /etc/aliases.db and then `dpkg --configure postfix' ran fine.

    There is still...
  2. [ubuntu] Re: Unable to install postfix atal: open database /etc/aliases.db: Permission denied

    Incidentally, this is happening on Dapper LTS. Also, it could have to do with some sort of package conflict, as I have two identical servers exhibiting this problem (one was cloned from the other...

  4. [ubuntu] Re: Unable to install postfix atal: open database /etc/aliases.db: Permission denied

    I'm having the same problem after a recent postfix upgrade. /etc/aliases.db does not exist and running postalias will not create it. I have tried removing /etc/aliases and rerunning the installer,...

    [ubuntu] Re: Trying to use ftp

    Yes. You can link, probably, from any OS you can get an SSH client running on. On Windows, I use the GUI WinSCP client, as I said. WinSCP has drag-and-drop integration with Windows Explorer...

    As Tim said, quite possible. I'll second most of what he said with the addition that I have occasionally fallen back on some GUI (even webmin) when I've found documentation for some task to be...

    [ubuntu] Re: Trying to use ftp

    I would just ignore FTP and use scp/sftp, unless you need to make the site public for some reason. scp/sftp is more secure and should work over your existing SSHD setup. The command line syntax is...

    [ubuntu] Re: Blocking users from SSH login

    Tim's second suggestion may be easier to implement: Set "AllowGroups" to "ssh" in /etc/ssh/sshd_config to allow only members of the "ssh" group to login.

    Otherwise, I'm not sure if webmin uses...

    Well, the Linode guys are pretty good about upgrades and the only upgrades they are needed for is the kernels anyhow. I can't argue with you about price, however, if you need that much disk and...

    [ubuntu] Re: Copy Large Files

    Why? I would have expected even cp to be smart enough to use reasonably sized chunks and stop reading and wait until its output buffer stopped blocking a write.

  15. [ubuntu] Re: Need help getting around in Ubuntu server edition

    googling "getting started on linux command line" brings up a handful of tutorials.

  17. [ubuntu] Re: Advice on setting partitions for RAID on server

    No, as long as you have similarly sized partitions on each disk to pair up, then you can use each partition for RAID without losing access to any disk space.
