[CentOS] xinetd custom service - perl - remote address
Hi all,
I can't believe that I can't find the answer to this one. I have a perl script
which is called by xinetd.
I want that perl script to be able to detect the remote IP address of the
caller.
I presumed that it would be an environment variable but I could be wrong. I've
found reference to the ENV and PASSENV arguments for xinetd.conf but no
examples, and no indication of what auguments to use.
In my script I have the following code:
foreach (keys %ENV) { print "$_=$ENV{$_}\n";}
but the only line I get back is:
XINETD_LANG=en_US

[CentOS] Replacement for KMail V1
Last week my trusty Fedora 9 file and print server failed on me. Not bad for 12 years trusty service. I have now replaced it with a C7 server and found that lots have changed in those 12 years. Thankfully many things haven't, named-chroot, dhcpd, etc pretty much copied across and Samba wasn't a major rewrite. However I feel like my right arm has been chopped off. My work life revolves around my emails which were in KMail version 1.x. My first thought was to move to the current KMail which is version 4.x. The problem is that it's cr*p. It appears to be the same as V1, but just more up to date - perfect. Unfortunately it is so slow that it is completely unusable, even on a brand new server. As a GUI it is unusable, and functionally fails with connections time out etc. Some research has found that KMail was stuffed as far back as V2 when they moved to using an embedded MYSQL engine to drive it. What I would really like is advice on how to make KMail V4 usable. As I doubt that is possible can anyone please recommend a decent email client with good keyboard short-cuts and filtering processes. I am currently limping along using Thunderbird but I find the lack of useful keystroke functions (such as next unread message, next folder with an unread message) annoying. Having to move my hand from keyboard to mouse is more exercise than I'm used to. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Thunderbird won't start after move to new box
I've tried moving my Thunderbird profile from one C7 box, a standard PC to another C7 box, a DELL server. I did this by rsync'ing ~/.thunderbird. However, on the new box, Thunderbird only starts if I run it -safe-mode. If I don't run it in safe mode I see the window flash up and instantly close. No errors or notifications appear in the terminal window., Anyone got suggestions on what could be wrong, or how I can diagnose it? Google just seems to bring up hits for problems on Windows boxes. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] Centos 7 + PHP7.2 - variables_order not working
I've just moved my site onto a new box and I'm having a real problem
with $_REQUEST. The variables_order and request_order values are not
being respected.
I need the cookies to take the lowest priority, so I put it first in the
sequence. However, as the code below shows this is not happening.
Changing variables_order and request_order does not make any difference.
Anyone got any ideas why? I've not seen this before.
PHP.ini settings
variables_order = "CGPS"
request_order = "CGPS"
The position of the 'C' seems to make no difference at all, but if I
remove it then I get the expected response.

[CentOS] System not logging
One of my boxes has stopped logging some of the things it's supposed to. I use rsyslog which used to send named and dhcpd entries to separate log files. Both named and dhcpd are working. I have shut down the DHCPD server and run it in debug mode and the output is produced as expected. I have shut down rsyslog and run that in debug mode and it looks like everything is running, but it's not receiving messages to log. I tried journalctl | grep -Ei 'dhcpd'|tail and I see the log entries for the service starting up, but no entries for DHCP transactoins happening. My rsyslog also receives network messages from my firewall and they are logging as expected. This suggests to me that the problem is that the log entries are either not being generated, or are not being allowed to get to rsyslog. Anyone go any ideas? I've tried the usual first step, and briefly disabled selinux but that made no difference Gary ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] GVIM annoyances
I've just upgraded from my old F9 box to C7, which of course means lots
of changes. However, the ones are are annoying me most are with VIM.
No matter what I do I can't get gvim to open in a reasonable size. I
have a dual headed setup (laptop + external) and every time gvim opens
it takes up both screens.
I've tried a few suggestions including the one below without success.
In fact this one causes X to crash when I start gvim.
The second problem I have is the selection of the font. My old box had
"sans Regular 12" which was a lovely font to work with. However, when I
choose the same font on the new box it's hideous. I don't know best how
to request this, but basically how can I have my nice old font back?

[CentOS] fail2ban problems - not banning
Hi everyone,
I've got fail2ban and firewalld set up on a C7 box, in theory protecting
dovecot, exim and ssh but I'm not convinced it's doing anything.

Re: [CentOS] clamav / EXIM on Centos 7 - workaround
The story so far: Even though I've got clamav-server-systemd installed I can't find any units etc to enable me to control clamd via systemctl. When I ran clamd in a terminal it complained that it couldn't find /etc/clamd.conf which made sense as it didn't exist. I copied /etc/clam.d/exim.conf from a F21 system to /etc/clamd.conf on this server. I then created /var/log/clamd.exim and /var/run/clamd.exim and re-ran clamd. It then ran, and worked fine with EXIM. I've obviously missed something as I'm certain that the RPM maintainers who provided all of the clam RPM's don't expect anyone to do this every time. In order to get this working I'm going to copy the unit file /etc/systemd/system/multi-user.target.wants/clamav-milter.service to create clamd.service and will then have a working system. However, I would love to know what I *should* have done to get this working. BTW, I've just received two lovely emails from a scantily clad young lady who wants to get to know me better.

[CentOS] /run and /var/run as tmpfs - how many RPM's broken?
This is pretty much a retorical question, although I would like to know the extent of the problem and how quickly it's gonna be sorted. My problem has already been described in a previous post, i.e. clamd fails after a reboot. The cause apparently is that /run and therefore /var/run has at some point been moved onto tmpfs which means that it doesn't survive a reboot. The effect of this is that any folders (such as /var/run/clamd.* that gets created when RPMs are installed don't survive, and the first time the server is rebooted things get broken. Googling the problem has shown at least a couple of other packages now experiencing the same problem. including from memory pcp and MongoDB.

I am trying to get LDAP working on my mail server for both user authentication and addressbook purposes. I have tried the tutorials on both http://www.server-world.info/en/note?os=CentOS_7&p=openldap&f=1 and http://albanianwizard.org/ubuntu-10-0-4-lucid-lynx-ldap-configuration-the-working-how-to.albanianwizard (The second one is for Ubuntu, but claimed to be a complete and working demo) However, when I try to last part of each of these tutorials I get the following. ldapadd -x -D cn=admin,dc=ringways,dc=com -W -f /tmp/dit.ldif Enter LDAP Password: ldap_bind: Invalid credentials (49) Note: in the server-world one I tried using "dc=ringways,dc=com" as well as leaving it as "dc=server,dc=world" but it didn't seem to make any difference.

[CentOS] Dovecot on C7.2 - secure internet access
I have a mail server running on Centos 7.2 which has been working for my LAN
for a long time.
I'm at the point where I have to make it accessible to the internet. At the
moment, access can be insecure but as it's on my LAN it isn't an issue.
However, for internet access I wish to force SSL/TLS. Having read the
documents I think it's as simple as changing 10-ssl.conf from
ssl = yes
to
ssl = required
remote 10.0.0.0/8 {
ssl = yes
}
Am I right in thinking that this would make the global value now force SSL/TLS
to be required, but for my LAN (10.0.0.0/8) override this with the old value
of 'yes'
Is there a better way to do this?
Have I missed anything?
I believe that this means implies
disable_plaintext_auth = no
for all except my LAN. Is that right?

[CentOS] old hardware / minimal netinstall -> CPU fan control
I have just installed CentOS 6 i386 onto an old rack server (it's gonna be a Bacula storeage server and is a 1U 1/2 depth chassis) I did a minimum netinstall and so far so good. However, I have one problem. The CPU fan is going at full speed constantly. Not a real problem apart from (a) it will affect the fan's lifespan and (b) it's noisy. I've done some Googling and found some help. I've installed lm_sensors and run sensors-detect. After reboot I get the following: [root@harpo ~]# sensors acpitz-virtual-0 Adapter: Virtual device temp1: +40.0°C (crit = +75.0°C) [root@harpo ~]# which implies that it can read the CPU temp, but the fan is still going at full speed.

One of the solutions that I've found is to add dns_server entries into the config file. As this did not entail updating the software this is the option I've chosen. This has fixed the original 'spf' error message, but now gives me a different error message. I now get one or more Use of uninitialized value $rr_type in string eq at /usr/share/perl5/vendor_perl/Mail/SpamAssassin/Plugin/AskDNS.pm line 592.

Local DNS resolution was working fine, with the correct entries in resolve.conf, and nslookup, dig, and all other services working fine. The research I had done into this error messsage stated that because of problems with Net::DNS SA had cheated and looked at the internals of the module to obtain the DNS list. These internals then broke which meant that SA could no longer detect the DNS servers. By adding dns_server x.x.x.x to the local.cf I got round this problem and the error messages have gone.

[CentOS] Centos 6 Airprint using CUPS/Avahi
I've set up another airprint server, but this time I've had to use Centos 6 because of the age of the kit I'm using - an old 1U rack server. I've configured CUPS and also Avahi. I've run airprint-generate.py and copied the .service files to /etc/avahi/services/ Everything looks fine until I try to print from my IPhone. I usually test by trying to print an email. As soon as I go to search / select a printer I get the following start to appear in /var/log/cups/error_log E [29/Aug/2017:15:24:07 +0100] Request from "10.1.103.237" using invalid Host: field "harpo.local:631" The printer list appears and I can select a printer and click on print. However nothing prints off, and I just keep getting the above error message. I've tried setting [server] host-name=harpo domain-name=ringways.co.uk in /etc/avahi/avahi-daemon.conf but that just prevents Avahi from starting.

Leon,
There's nothing wrong with being pedantic, and thanks for the command. It was
very useful. However, for the box that has the problem, it's not worth the

Mark, Many Non-Centos originated packages create directories in /var/run as part of the install, and expect them to still exist after a reboot. They then fail when starting the service because they're trying to create a PID / Lock file in a directory that no longer exists. This problem has been around ever since /var/run was moved to tmpfs. Unfortunately, sometimes we have to use packages other than the official Centos ones, usually as in this case because we need newer versions.

Before Packages were introduced, everyone compiled from source. That was a pain, and a long process, especially when you had dependancies that you also had to compile. Packages eased this process but kept the dependancy issue. Package managers got round (mostly) both the dependancy problem and updating too. The problem with package maintainers not keeping up to date shows that this still isn't perfect. However, if you go back to compiling from source then you lose all of these benefits. > > Why is it so hard for people to understand that var/run IS NOT > PERSISTENT and was never meant to be?

Thankfully I do not earn my keep by watering lawns.

Re: [CentOS] HP laptops with CentOS 7?
I've got a HP Envy laptop and I'm fairly happy with it. The internal WiFi doesn't work with Centos but a £5 WiFi dongle sorted that. Oddly, it still stops working once the battery drops below 50% ish. Mine is dual boot with Win8 which is pants. The biggest problem is that whenever I do much with the config, e.g. when I re-installed centos, the boot loader doesn't sort properly and I have to fiddle with it.

Re: [CentOS] Broadcom BCM4352 on Centos 7
After getting nowhere with the mokutil command I decided to use the other option and turn off secure boot in the BIOS settings. I had been loathed to do this because every time I do anything in the BIOS it stuffs the boot order and reverts to booting straight into Win8. Guess what, as soon as I turned off secure boot it did exactly that. Turnng secure boot back on made no difference. Thankfully, the mailing list archives for this list still contain the instructions on how to fix it. For those interested, it involved pressing F9 at boot time to select the boot menu and selecting the Centos option. This then went through GRUB as normal and booted. I then used 'eftbootmgr -o' to define the correct boot sequence. The upshot is that I now have a laptop that boots correctly, and that successfully uses the built in Broadcom WiFi adaptor.

[CentOS] OT - pushing database updates to web browser
This is O/T apart from the fact that the server is Centos running Apache / Postgresql. I want to develop a real time (ish) dashboard type web page showring extracts of the contents of a table. I would like any changes that occur to be pushed to the web clients rather than have the clients poll the database. Based on the fact that I have not managed to come up with a successful Google search phrase I think this may not be possible, but just in case I thought I'd ask here. If it's not possible, can anyone suggest the most efficient / responsive polling techniques? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Looks a very interesting article, and exactly what I'm looking for. Thanks Leon for your reply too.

[CentOS] Centos 7 LAPP setup Postgresql version and setup
Hi all, I've got a nice shiny new server which I'm going to build as a LAPP platform. I've just had a quick look for suitable instructions on the best way to configure it and I have a few questions. There are many hits, some better than others. (It is replacing a Fedora 9 server so I'm expecting to have lots of *fun*) 1) 9.2 vs 9.5 Some of the instruction pages I've found install using the standard repositories and install version 9.2 (?) while some others add a postgresql repo and install 9.5 What are people's opinions? In the long term, and I going to have more admin hassle with one over the other? Will porting schemas including stored functions in pl/psql from 8.3 be easier / better with one version over the other? 2) network vs sockets I read somewhere that connecting Apache / PHP to Postgresql is faster if you use sockets rather than usling the loopback i/f. Is this correct? If it is correct, what is the correct connect string if I use the 9.2 or 9.5 RPM's as described above? There seems to be lots of Google content about sockets not working.

[CentOS] Centos 7 LAPP setup PHP 5 vs 7
Another questions regarding my new server setup. As with the Postgresql setup, different pages describing setting up a Centos LAPP server have differing opinions about PHP versions. The default distro's appear to still be installing PHP5 while some sites instruct on how to install PHP7. I am porting my old server which must be 10 years old, running Fedora 9 and PHP5 onto the new server, so presumably sticking with PHP5 would be the easier option. However, I am looking to give my new server as long a life as possible, so should I instead be looking at PHP7? I have literally thousonds of lines of PHP code on my existing box. How much head ache am I going to have porting into either of the two new platforms? How much difference would PHP5 vs PHP7 be?

[CentOS] Windows PC PostScript printer driver -> CUPS data import fails
Hi all, For some years now I have been using a simple system I found online which allows me to easily import data from Windows Programs. Hopefully others out there are using the system and already have found the answer to my problem. I have installed on my Centos server a virtual CUPS printer which receives a PS file, and then runs 'ps2pdf' and 'pdftotext -layout' to end up with a text file. On the Windows PC's it's simply a case of installing a printer pointing to this server, and using the HP Colour Laster 2800 PS drivers. Now to my problem. We have finally moved onto Windows 10, and now when I try to install the printer that model printer is no longer available. When I try similar HP Colour Laser PS drivers the ps2pdf command fails.

I will try these two options if I need to. However, I have found in Windows 10 there is a printer driver Microsoft "Print to PDF" which creates a PDF file without the initial PS stage. This is better because it now keeps some of the non-display characters that the original method lost. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] yum hangs and results in problems
My live mail server was due an update so I ran
yum update
All seemed file so I told it to proceed. HOwever it then hung for over 30
minutes.
I stopped the update and tried again. It complained about problems with the
update, so I tried
yum --skip-broken -y update
which then hung at a different place. After some Googling I tried
yum-complete-transaction
and
package-cleanup --cleandupes
both of which failed. I then using my "Microsoft" head I thought I'd try
rebooting to see if that fixes it. This of course was a big mistake as my
server now crashes on bootup.
I have managed to get it back up and running by selecting a version of the
kernel that is 3 versions old.
I have now tried
yum history
yum history remove 115 (which failed)
package-cleanup --cleandupes (which failed)
yum-complete-transaction (which failed)
yum-complete-transaction --cleanup-only (which worked)

[CentOS] New mail server slow connecting to web server
Having successfully killed my (Centos 7) mail server I have had to build a new one. Thankfully I had a server build that I was about to start configuring as my new web server. I appear to have set everything up okay, Exim, SpamAssassin, ClamAv, Dovecot, Postgresql, httpd etc. Everything appears fine apart from when I try to connect to my web server. Whatever tried to connect suffers from a delay, and either times out or works eventually. I started off with problems connecting Exim to Postgresql on the web server. I then found that I couldn't connect using psql, or using Perl DBD-Pg. I then found I couldn't SSH or SCP, dispite them both being on the same subnet. The more I use the new system, better it appears to be, but the delay is still there. name resolution isn't the problem as I can nslookup both ways without problems, and specifying IP addresses makes no difference. For testing I have disabled the firewall and selinux and that made no difference. If I try to connect the other way there is no delay, but I cannot access the Postgresql server on my new mail server from the web server. Anyone got any ideas? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] installing perl-CPAN without perl-local-lib
I'm still working on getting my brand new Centos 7 mail server working and I'm having problems with Perl. Most of the modules are available as RPM's which was straight forward. However, MIME::Parser, Net::SCP and Net::SSH aren't. In order to get these working I installed the perl-CPAN rpm and then installed the modules above. Doing this, installed perl-local-lib.noarch as a dependancy. The problem now is that when I used CPAN to the above modules they installed without errors, but were only available to the root user.

Hi Warren, I had considered power consumption but only with regard that it is a small footprint system, both physically and in terms of processing power etc. I had not considered the lack of energy efficiency. The server has a MSI MS-9628 board with a Pentium M processor, and the one modern 4TB HDD. There is one tiny fan in the PSU and another tiny processor fan on the CPU. From this I (possibly wrongly) assumed power consumption would be low. It used to have 2 x 1.5TB drivers with software RAID until that died. I am still in the process of installing lubuntu so I don't know how effective it will be. I had considered putting Centos6 32-bit back on, but has been said elsewhere that's very near EOL.

However, when I tried lubuntu the Bacula versions were not compatible. Now Putting Centos 6 32-bit back on and crossing my fingers.

[CentOS] Scroll bar arrows missing and behaviour change
I have done some Googling on this but everything I've found appears to be at least 2 years old and mostly refers to Gnome TBH, I'm surprised nobody else has mentioned it - maybe it's only happened to me. At some point over the last few months the behaviour of the scroll bars changed and I'm finding it very annoying. Firstly, the arrows have vanished. Secondly, when clicking on the scroll bar background either above or below the drag bar instead of doing a page up or page down which is what it used to do (and what I want it to continue doing) it now moves the scroll bar to that absolute position, i.e. if I click on 75% down the scroll bar it jumps to 75% of the document. As this is happening in all apps I'm assuming it's something within KDE that had changed. I'm running an up-to-date Centos 7 x64 running the KDE desktop. Anyone got suggestions on how I can get back the the old style (windows clone) behaviour and appearance? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] Still getting Dropbox warning at login after uninstalling Dropbox
Lke many people I have received the message from Dropbox about their changes including the non-support for the old Linux RPM. As I no longer use Dropbox I thought I would just remove the nautilus-dropbox RPM. However, I am still receiving the warning every time I log in. Can anyone tell me what I need to do to stop this please. Gary ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Firefox showing bogus sites after 'yum update'
I have just done a yum update for the first time in a while, and as part of that I believe Firefox got upgraded. After the reboot I restarted Firefox which had been closed down with the option to retain all open tabs/windows. However, when I restarted Firefox it had three new tabs, one being the ususal Firefox upgrade page. The other two were Phishing sites, one pretending to be Amazon the other I cannot remember. Has anyone else experienced this? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Help finishing off Centos 7 RAID install
I've just finished installing a new Bacula storeage server. Prior to doing the install I did some research and ended up deciding to do the following config. 6x4TB drives /boot/efi efi_fs sda1 /boot/efi_copy efi_fs sdb1 /boot xfs RAID1 sda2 sdb2 VG RAID6 all drives containing SWAP / /home /var/bacula Questions: 1) The big problem with this is that it is dependant on sda for booting. I did find an aritcle on how to set up boot loading on multiple HDD's, including cloning /boot/efi but I now can't find it. Does anyone know of a similar article? 2) is putting SWAP in a RAID a good idea? Will it help, will it cause problems? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
