    Redhat 7 wuftp

    Heya kids,

    I'm running Redhat 7.0 with wuftp. When I connect via dos prompt, I get a Connect to (ip addy) and it takes about 60-120 seconds before I get a login prompt.

    Any thoughts???

    Mike,

    My son, who is the Linux Guru in the family, swears that RedHat 7.0 is dangerous to use. Claims that it was built with a beta C compiler which introduced some *strange* bugs.

    The problem(s) were supposed to be fixed in RedHat 7.1 (which I use).

    I will try to test the problem here and see if I can replicate it in 7.1.

    Heya Ian,

    I talked to a co-worker and he said it was a problem with wu-ftpd, so I installed pure-ftpd and everything is great. I'm also going to upgrade to 7.1. Thanx a bunch.

    Mike, the problem you were having is indicative of having a bad reverse DNS loookup. To fix this, you must set up your DNS configuration with the correct reverse DNS entries for your network and machine. Please check the book "DNS and Bind" by Cricket Liu et al for instructions. Red Hat's web site offers significant support resources to help you also. The Linux Documentation Project also publishes many HOW-TOs that will assist you with networking issues and possibly even DNS issues. Since getting your DNS straight is key to a lot of intranet and internet web-based services I would think reading the book is your best option and time well spent for you.

    Red Hat 7.0 did ship with a beta version of the GCC compiler, but the compiler is not an issue here. The current version of Red Hat is 7.2 and upgraded versions of GCC are of course available.

    Mike, a postscript: I checked the pure-ftpd documentation and I figure you must be starting pure-ftpd with the -H flag to disable DNS lookups if you are saying everything is great with this product. Changing ftp products does not necessarily correct underlying forward or reverse DNS lookup problems.

    Also, here is a related hint (which again involves DNS..!) Because of the way DNS lookups are done, if you telnet to a server using this string:

    telnet server1.anywhere.com.

    instead of this

    telnet server1.anywhere.com

    The first string is terminated with a dot '.' and the second is not. The first string is more efficient and can result in a quicker connection. Likewise,

    ftp ftp.anywhere.com.

    should result in a quicker connection.

    Let me stress that this assumes you have the named daemon running and that named.conf is correctly configured with forward and reverse DNS zones.

    Actually the current RedHat version is 7.3, but 7.2 is fine. Among other things, I think 7.3 incorporates KDE3 which fixes some problems with KDE 2 which was included in Red Hat 7.2.

    Woops! I just noticed the dates on these posts. I guess 7.2 was the newest at the time of the postings.
