    • RE: Win 10 + older HP laserjet printers

      Interesting enough, I changed the usb port ( new workstation) from the usb 3 port to the usb 3.1 port, and it started working as expected, (using the pcl5 driver I had installed earlier) Why, I do not know. When I examine further I will update.
      Thank you for your comments.

    • RE: Win 10 + older HP laserjet printers

      @black3dynamite Yes i did, i installed the pcl5 drivers from their website , the .inf etc.
      I didn't look at any of the event logs, ( sigh), I had better do that before I make more submissions.

    • Win 10 + older HP laserjet printers

      Having trouble getting an older HP laserjet (4300 series) to work on a recently upgraded win 10 workstation. I have in the recent past, used older drivers ( pcl5) and was worked well. printer connect with centronics to usb cable, and Win 10 does recognize the printer.

      Does anybody know of a simple utility to convert .cgm files into something more common, less proprietary ?

    • RE: How do you find duplicates from Windows SMB shares using Linux

      @pattonb to get an idea of how many dupes use the following

      fdupes -r -m /directory(share to scan)

    • RE: How do you find duplicates from Windows SMB shares using Linux

      @DustinB3403 some folks claim jdupes is faster, I have used both, and did not much of a difference.
      Both work well.

    • spf include option

      is it prudent to use cidr notation for an include record in a SPF record, or is a fqdn acceptable ? or both ?

    • RE: DNS PTR Record with 2 FQDN Entries with SPAM Check

      @JaredBusch correct, they are tools to determine validity of incoming email. If you have a mail server , ( I would think with a static ip), why you wouldn't have a ptr record that matches your mailserver, is asking for issues.

      @JaredBusch SPF has it flaws, however, in this case , ptr check yields 2 fqdn, and no listing in the SPF to confirm validity of sender.

    • RE: DNS PTR Record with 2 FQDN Entries with SPAM Check

      @scottalanmiller ok, thanks, I am sure it isn't a spammer, it is an email, for me, I was expecting. The sender 'city of calgary"
      has their ptr record setup that way.

    • RE: DNS PTR Record with 2 FQDN Entries with SPAM Check

      @scottalanmiller I have read it. the question is/was, how do you deal with this situation when it occurs (rarely), is there a way other than whitelisting the offending ip for the ptr. and the ip is listed in their spf list.

      @JaredBusch the question is more about a ptr record

    • RE: DNS PTR Record with 2 FQDN Entries with SPAM Check

      I thought there was an rfc that stipulates, 1 fqdn with 1 ip per ptr record.

    • RE: DNS PTR Record with 2 FQDN Entries with SPAM Check

      I should clarify, the ptr record single ip) has 2 fqdn, how does zimbra ( or any mailserver), know which fqdn
      to verify, My understanding it attempts to verify the 'greeting' sever by doing a ptr lookup, and if it doesn't match, then
      the attempted connection is rejected, as there is a mismatch with the sending server, and the ptr record.
