Hi David,

Hope you are well!

Do you mind sharing the steps/procedures that was taken to upgrade xymon-client from 4.3.28 to 4.3.30

I'm relatively very new to xymon and can't find the steps.

I have recently upgraded from 4.3.28 to 4.3.30

Everything seems to have installed ok, without any issues.

The problem I think I have is the http(s) test for the actual xymon server, on version 4.3.28 the test worked ok and I got a green result Since upgrading the test now shows red, it actually sayshttps://vmsg-xymon1.corp.renfrewshire.gov.uk/ - Bad Request

HTTP/1.1 400 Bad Request Date: Tue, 11 May 2021 09:59:47 GMT Server: Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips mod_wsgi/3.4 Python/2.7.5 mod_perl/2.0.11 Perl/v5.16.3 Content-Length: 362 Connection: close Content-Type: text/html; charset=iso-8859-1

Seconds: 0.002957000

On my other xymon server which is still the older version, same test is ok.

The other thing I noticed is that on the xymonnet test on each server, on version 4.3.28 it shows SSL library but on 4.3.30 it does not.

Any ideas or suggestions are most welcome

David

Hi there,

I?m a bit rusty on this?

My Xymon has the SSL libraries displayed in the xymonnet test:

xymonnet version 4.3.30 SSL library : OpenSSL 1.1.1d 10 Sep 2019 LDAP library: OpenLDAP 20448

I believe you can compile Xymon without SSL support.

You should be able to check the xymonnet binary with the ldd command (using the path where you installed xymonnet of course):

ldd server/bin/xymonnet | grep ssl

    libssl.so.1.1 => /lib64/libssl.so.1.1

If you haven?t got SSL compiled in the https tests will not work.

Hi Rajesh,

Here are my notes on my install. I continued without using HTTPS. Good luck!

XYMON Server Install:

It is strongly encouraged that the server be installed only on one or two machines. The client data will reside on these machines. This method will prevent the wasting of disk space.

```
  Create the xymon userid
```

groupadd xymon

useradd ?g xymon ?m xymon

```
  Yum updates needed
```

yum install gcc make

yum install pcre-devel openssl-devel openldap-devel rrdtool-devel rrdtool

yum install yum install libtirpc-devel libtirpc

*Note: RRDTOOL-DEVEL is only available in the RHEL Server Optional (v. 6 IBM System z) channel*

*RHEL7 - subscription-manager repos --enable=rhel-7-for-system-z-optional-rpms*

*RHEL8 - subscription-manager repos --enable codeready-builder-for-rhel-8-s390x-rpms or downloadable from Redhat:*

https://access.redhat.com/downloads/content/rrdtool/1.7.0-16.el8/s390x/fd431...

https://access.redhat.com/downloads/content/rrdtool-devel/1.7.0-16.el8/s390x...

   Note: Error: /usr/bin/ld: cannot find -ltirpc,  collect2: error:

ld returned 1 exit status*

  [root at web02 tmp]#  wget

https://downloads.sourceforge.net/libtirpc/libtirpc-1.2.5.tar.bz2

[root at web02 tmp]# yum install bzip2

[root at web02 tmp]# bzip2 -kd libtirpc-1.2.5.tar.bz2

[root at web02 tmp]# tar xf libtirpc-1.2.5.tar

[root at web02 libtirpc-1.2.5]# ./configure --prefix=/usr \

--sysconfdir=/etc \

--disable-static \

--disable-gssapi && make

[root at web02 libtirpc-1.2.5]# make install

[root at web02 libtirpc-1.2.5]# mv -v /usr/lib/libtirpc.so.* /lib

[root at web02 libtirpc-1.2.5]# ln -sfv ../../lib/libtirpc.so.3.0.0 /usr/lib/libtirpc.so

    Or remove it from the Makefile, Another option is to remove

"-ltirpc" from the Makefile that has been generated after ./configure is run.

    Install all dependencies. This is stored in the M drive under the

XYMON software folder:

rpm -i dejavu-fonts-common-2.35-6.el8.noarch.rpm

rpm -i dejavu-sans-mono-fonts-2.35-6.el8.noarch.rpm

rpm -i rrdtool-1.7.0-16.el8.s390x.rpm

rpm -i rrdtool-devel-1.7.0-16.el8.s390x.rpm

  Install fping at the root home directory

? wget http://fping.org/dist/fping-3.2.tar.gz

? tar zxf fping-3.2.tar.gz

? cd fping-3.2

? ./configure

? make && make install

? cd ..

? rm ?rf fping-3.2.tar.gz

```
  install xymon software
```

? wget ftp://odcdocs.in.dc.gov/archive/Utilities/xymon-4.3.28.tar.gz

? tar zxf xymon-4.3.28.tar.gz

? cd xymon-4.3.28.tar.gz

? ./configure.server

    Answer yes to fping

    yes to SSL

    yes to LDAP

    Choose the default for the rest of the options and specify the IP

address of the server

? make && make install

? Configure Apache with the Xymon definitions:

ln -s /home/xymon/server/etc/xymon-apache.conf /etc/httpd/conf.d/

o Required Modififications:

Modify xymon-apache.conf to be only /xymon and not /xymon/

o Update xymon-apache.conf with the following:

Alias /xymon "/home/xymon/server/www"

Options Indexes FollowSymLinks Includes MultiViews

Order allow,deny

Allow from all

</Directory>

ScriptAlias /xymon-cgi/ "/home/xymon/cgi-bin/"

AllowOverride None

Options ExecCGI FollowSymLinks Includes

Order allow,deny

Allow from all

</Directory>

ScriptAlias /xymon-seccgi/ "/home/xymon/cgi-secure/"

AllowOverride None

Options ExecCGI FollowSymLinks Includes

Order allow,deny

Allow from all

o If there are errors like this in start up:

Directory index forbidden by Options directive: /var/www/html/

Search for :

grep -iR 'Indexes' /etc/httpd/*

If you use + for one option, you have to use + or - also for the others. Remove all + or ? as needed. See the following article for an example: http://www.linuxquestions.org/questions/linux-newbie-8/apache-directory-inde...

```
  Automatic start of xymon server
```

? Copy rpm/xymon-init.d to /etc/init.d/xymon

? Edit /etc/init.d/xymon and change "/usr/lib/xymon" in the DAEMON line to the directory where you installed Xymon - e.g. "/home/xymon/server/bin/xymon.sh".

? chkconfig --add xymon

? chkconfig xymon on

```
  Give permissions
```

chmod a+x /etc/init.d/xymon

chmod +x ?R /home/xymon

chmod 755 /var/log/messages

chmod -R 0775 /home/xymon/server/www/rep

chmod -R 0775 /home/xymon/server/www/snap

chown apache:apache /home/xymon/server/www/snap

chown apache:apache /home/xymon/server/www/rep
