    Selective DNS-Editor problem when adding CNAME type records

    in General Discussion

    Posted

    Update #2: And it does not work really. The zone is generated, but not loaded.
    Oct 23 13:44:26 server named[8798]: dns_master_load: /etc/bind/domains/domain.de.zone:8: domain.de: CNAME and other data
    Oct 23 13:44:26 server named[8798]: zone domain.de/IN: loading from master file /etc/bind/domains/domain.de.zone failed: CNAME and other data

    Maybe it is not possible to set a CNAME record for the TLD ("@") itself. Never needed this before. Will look further into it.

    Update: Now I was able to set the "@" CNAME-Record for my "case A", but not in a way that makes sense...
    Being desperate, I experimented with deleting the "@ MX" Record (!), and after that, there was no "conflict" anymore and the end result looks like this.
    I fortunately was able to do this in this productive case, because, luckily, the MX works also with the implicit default entry in this case, phew :)
    (Some customers have MX-Records not on our server, where this move would not have been possible)

    So some bug, after all 🙂

    "froxlor_master_cronjob.php --tasks" throws some PHP Warnings

    in General Discussion

    Hi!

    Yes, name resolution in general is fine on this machine.

    After looking at some articles like this:
    https://bugs.php.net/bug.php?id=73149
    https://stackoverflow.com/questions/36280957/dns-get-record-a-temporary-server-error-occurred
    https://dustri.org/b/a-short-tale-on-phps-dns_get_record.html

    ...I included a 'var_dump(' ... in the lines that were mentioned in the error message(s). (226 + 228 + 229) of .../froxlor/lib/Froxlor/PhpHelper.php
    and did a:
    # /usr/bin/php -q /var/www/html/froxlor/scripts/froxlor_master_cronjob.php --run-task 4 --force

(...and so on...)

    I'm not entirely sure how to intepret it.

    PS: If I run this multiple times and 'diff' the output file, the result is identical. It fails for like ~25 entries, of the many hundreds in our system.
    Anyway, I can't see a production or productive impact of this at the moment.

    backups

    in General Discussion

    Posted

    Hello there!
    Just my 2 cents of experience here. We follow a two-sided approach here.
    For having a consistent bootable desaster-backup for "*.*" we use this: https://www.veeam.com/linux-backup-free.html
    The base product is free. To quote d00p: There are so many backup solutions out there to choose from.
    On the other hand, for having some consistent database-backup rotation on the machine itself at hand for quick access and restore, I scripted this:
    (Run by crontab which has 'MAILTO=' defined (important in my eyes in general ! ) 

    #!/bin/bash

#############################
export login=debian-sys-maint
export password=`grep password /etc/mysql/debian.cnf |tail -1|cut -d"=" -f2|sed 's/ //g' `
#############################

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

find /localbackup/ -type f -mtime +3 -iname "*gz" -exec rm {} \;

mkdir -p /localbackup
day=`date +%Y%m%d`

echo $day - Starting Backup of all current local databases

mysql -s -r -u $login --password="$password" -e 'show databases' -N | while read dbname; do
    echo Work at - $dbname
    mysqldump -u $login --password="$password" --complete-insert --single-transaction "$dbname" | gzip > /localbackup/$day-"$dbname".sql.gz;
done

echo Done

    -> Depending on the actual distribution you use this may need some adjustments of course. For me it was important to have something with no included fixed credentials :)

    -> Result: All DBs in existing, compressed in one directory, with a (in this case) +3 day rotation.

    Greets,
    Sebastian

    Selective DNS-Editor problem when adding CNAME type records

    in General Discussion

    Posted

    Hi there!

    As the following issue is not affecting all our domains in the DNS editor, I post it here before filing a bug in github.
    We have an two-parted issue with adding CNAME-records to DNS zones using the Froxlor DNS-Editor.
    I have for example two DNS zones here, which behave very differently when adding CNAMES.

    -> Please see attached two pictures as information basis

    Case A:
    Problem 1) When adding an "@" CNAME to this zone this happens: There already exists a resource-record with the same record-name. It can not be used as CNAME.
    Problem 2) When adding an "www" CNAME entry to this zone this happens: The entry gets duplicated -> TWO "www" entries exist, and the zone is not loaded due to error. The "custom" enty is not respected in the usual manner: It should be replaced.

    Case B:
    - Both things simply work like a charm :)

    Neither do I see what I am doing wrong, or in which way there are different that this may happen. I even had a look into 'domain_dns_entry' table, which did not reveal a conclusion for me here.
    Froxlor Version: 0.10.21

    Many thanks in advance,
    Sebastian

    "froxlor_master_cronjob.php --tasks" throws some PHP Warnings

    Hi there,
    I'm looking for a hint on how-to debug the following output from "/usr/bin/php -q /var/www/html/froxlor/scripts/froxlor_master_cronjob.php --tasks": 

    PHP Warning:  dns_get_record(): A temporary server error occurred. in /var/www/html/froxlor/lib/Froxlor/PhpHelper.php on line 226

    It probably has something to do in context with: "gethostbynamel6" function in there. 

    We're not actively/productively using IPV6 (yet). The only thing we have (so far) configured it is in the menu item "IPs and Ports" for some tests in the past. But there should be no BIND-zones with IPV6.
    The occurence of this issue is new. It came up after the major update from 0.9x to 0.10.x

    Best regards,
    Sebastian

    Froxlor Update 0.9.40.1 to 0.10.21 fails (Browser hanging for >10 Minutes, then error)

    in General Discussion

    Posted

    Hello there!

    We are using Froxlor since a couple of years and never had an issue updating.
    At the moment >700 domains are in our main system.
    Now we tried to finally update our installation from 0.9.40.1 to 0.10.21 using the usual .tgz-method, but unfortunately failed.
    Login is displayed (after exchanging files and reloading) -> Login gets accepted -> Update confirmation notice is displayed -> Confirmation clicked -> Browser hangs (for >10 minutes)

    Result: "Internal Server Error" and error.log just displays: "End of script output before headers: admin_updates.php"
    I even had to increase "FcgidIOTimeout" to not having it timeout (I made several attempts, backing up files and db beforehand).

    Any hint will be greatly appreciated. Many thanks in advance!

    Regards,
    Sebastian
