Two pieces of ambient music.
I was working today and to be in the right mood I had to listen two tracks in the loop:
• Biosphere - Kobresia (Track 7 from the album called “Substrata” released in 1997). This track has interesting sample in it - Speech in Russian sampled from a documentary recording about Russian telepath Karl Nikolaev, who is sitting in a room trying to guess which item is lying on a table situated in a room two floors above him. This sample is taken from a Moscow radio broadcast translation.
• Aphex Twin - Tha (from “Selected Ambient Works 85-92” released in 1992).
Linux CentOS - 100% disk usage. [SOLVED]
Quick note on how to fix an issue with Linux machine that has 100% disk usage. After doing it more than 20 times for the last 3 years I decided to put something here:
So, in my case I had CentOS with 100% disk usage for root partition:
[root@hostname ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos_hostname-root 17G 17G 20K 100% / devtmpfs 903M 0 903M 0% /dev tmpfs 915M 0 915M 0% /dev/shm tmpfs 915M 89M 826M 10% /run tmpfs 915M 0 915M 0% /sys/fs/cgroup /dev/xvda1 1014M 181M 834M 18% /boot tmpfs 183M 0 183M 0% /run/user/0 [root@hostname ~]#
I was luck and quick search for files that are greater than 1GB revealed an issue - standard log messages occupied too much space:
[root@hostname ~]# find /var/log -size +1G -print0 2>/dev/null | xargs -0 ls -lhS -rw------- 1 root root 8.4G Sep 14 15:08 /var/log/messages-20200914 -rw------- 1 root root 4.8G Sep 6 03:26 /var/log/messages-20200906 [root@hostname ~]#
Quickest solution is to make “logrotate” rules a bit tighter: start compressing historical files, compress more often OR if a file reaches certain size maybe keep less number of them. All I did is modified “/etc/logrotate.conf” by adding the following lines to enable file compression and max file size:
vi /etc/logrotate.conf compress maxsize 50M
Then forcibly run logrotate to see the result:
logrotate -fv /etc/logrotate.conf
Next step is to see if/when something changed by looking at the file sizes (files are sorted by date, “-t” option):
[root@hostname ~]# ls -laht /var/log/messages* -rw------- 1 root root 8.4G Sep 14 15:07 messages -rw------- 1 root root 4.8G Sep 6 03:26 messages-20200906 -rw------- 1 root root 822K Aug 30 03:49 messages-20200830 -rw------- 1 root root 807K Aug 23 03:28 messages-20200823 -rw------- 1 root root 822K Aug 16 03:29 messages-20200816 [root@hostname ~]#
It was easy to notice that something changed after Aug 30th when files size changed drastically. I found what happened by looking at file content and modified “/etc/rsyslog.conf” to fix the root cause, but it’s something too specific that doesn’t apply to everyone, but I hope you learned something.
Good luck!
Cyclades-TS3000 Console Access and Terminal Server
I’ve been using numerous different access servers during my career and after doing it for so long I settled with my preference list of vendors - Lantronix, Opengear, Cisco. Final choice depends on many factors, but today I’d like to make a quick note on yet another Console Access and Terminal Server - Cyclades-TS3000.
It is 48-port “console concentrator” or “access server” or “terminal server” (whatever term you prefer) from the company called “Cyclades Corporation” (cyclades.com) that was founded in 1991 and used to be located in Fremont, CA. Cyclades has grown from a provider of serial communications cards for Linux to the proven worldwide leader in Out-of-Band Infrastructure (OOBI) management solutions. Cyclades had two series of terminal/console servers such as “Cyclades-TS” (released in 2001) and “AlterPath ACS” (released in 2002). Later in 2003 Cyclades Corporation added “AlterPath KVM” to their portfolio to cover pretty much all the needs in terms of out-of-band management of different hardware in DataCenters.
To understand company’s vision we can read “Introducing Cyclades” paragraph in User Guide for any of their products:
Cyclades is a data center fault management company that enables remote management of servers, network equipment and automation devices. Its products help data center managers at enterprise, telecommunication and Internet companies to maximize network and server
availability. This results in decreased maintenance costs, increased efficiency and productivity, along with greater control, freedom and peace of mind. Cyclades’ advantage is providing scalable products leveraging Linux technology for flexibility and ease of customization.
In 2006 Cyclades Corporation was acquired by Avocent which was acquired by Emerson Electric in 2009. In 2016 all of that was rebranded under the name Vertiv. Company names sound familiar. Right?
Let’s go back and take a look at TS3000 model and its specs:
• Model: Cyclades-TS3000
• Hardware: MPC855T PowerPC Dual-CPU with 128MB RAM and 16MB CompactFlash (removable, but you have to open a chassis).
• Latest software: Cyclades-TS3000-Linux V_1.4.0-3 (Dec/16/04)
• Ports: 1xEthernet 10/100 (RJ45), 1xConsole (RJ45), 48xSerials (RJ45).
• Console cable pinout: RJ45-RJ45 “rollover” cable, not changeable/programmable. You can use “Cisco Console Rollover Adapter for RJ45 Ethernet Cable” for regular “straight-through” cables.
• Quality of hardware: I got to tell you that this chassis has exceptional quality build. This is one of the best chassis I’ve ever touched comparing to all other terminal servers I’ve been using. It’s relatively compact, heavy (which in most cases a good sign), it has great ergonomics (all the ports are on just one side of chassis). Nothing looks cheap or flimsy. Even painting after 15 years looks just awesome including properly designed mounting ears. Whoever did the design of the chassis did a perfect job! No wonder why this company was acquired by Avocent (a giant company) and kept this product for very long time. Even now, newer generations of terminal servers from Vertiv look pretty much the same with almost the same basis functionality.
• Current price: $100 on Ebay.
For those who familiar with Avocent products this exact model will look and feel very familiar and easy to grasp, but there some differences. There’re a lot of nuances that I’m not going to cover here, but here is a quick start guide:
• Connect to Console port using regular RJ45 cable (regular Cisco aqua console cable will work) and 9600-8-N-1 parameters.
• Power up the box. You should see something like this:

TSx000 login: root Password: tslinux Welcome to Cyclades TS-Linux version 1.4.0-3 This product runs an embedded version of the Linux kernel. Even if you are an experienced Linux user, please do NOT use the generic system tools for networking configuration. Please consult the latest version of the user's guide, which is available for download from the Technical Support area of the Cyclades website, before configuring this product. Chapter 2 of the User's Guide details the configuration process. Here is a summary of what you need to do in order to get the product working: 1) Modify the files: /etc/hostname, /etc/hosts, /etc/resolv.conf, /etc/network/st_routes and /etc/portslave/pslave.conf. 2) Activate the changes (signal_ras hup). 3) Make sure the configuration is working fine. 4) Save the configuration into flash (saveconf). Also, if you are upgrading from a previous firmware version, read the document "/upgrade_notes" that provides the information you need to setup your TS properly. [root@TSx000 /root]#
• Reset configuration to factory default by executing the following commands:
[root@CAS /root]# echo > /proc/flash/script [root@CAS /root]# reboot
• The box will be rebooted and if everything goes right it should come up with default hostname “TSx000”. Relogin using default credentials: root/tslinux.
• Change default root password to something else by using regular command “passwd”, then save the config using “saveconf” command:
[root@TSx000 /root]# passwd Enter new UNIX password: NEWPASS Retype new UNIX password: NEWPASS [root@TSx000 /root]# saveconf Checking the configuration file list... Compressing configuration files into /tmp/saving_config.tar.gz ... done. Saving configuration files to flash ... done. [root@TSx000 /root]#
• Start configuration wizard by typing “wiz” and setup basic parameters.
[root@TSx000 /root]# wiz *********************************************************** ********* C O N F I G U R A T I O N W I Z A R D ********* *********************************************************** INSTRUCTIONS for using the Wizard: You can: 1) Enter the appropriate information for your system and press ENTER or 2) Press ENTER if you are satisfied with the value within the brackets [ ] and want to go on to the next parameter or 3) Press ESC if you want to exit. NOTE: For some parameters, if there is nothing within the brackets, it will continue ▒ ask for a value. In that case, you must enter a valid value or # if you do not wish to configure the value. Press ENTER to continue...
• After changing, applying and saving configuration TS3000 will be accessible via TELNET, SSH and WEB. BTW, Web GUI looks decent and probably looked just awesome for year 2004, but I was not able to make “Connect to Serial Ports” option to work. Regular configuration setting/knobs work fine.
• By default all serial ports are configured for 9600 baud rate. To change it via CLI:
# To change baudrate for serial port 2 to 115200: config configure line 2 speed 115200 # You can also put a range of ports. If you'd like to change it for all 48 ports do this: config configure line 1-48 speed 115200 # Activate changes: signal_ras hup # Save the file to the flash: saveconf
• Here is how yo can change port speed via GUI: “Configuration” > “Serial Ports” > “Logical Port:” select Port X from drop-down menu > “Submit” > change “Speed (bps)” > “Submit”. Apply/Activate configuration changes by going to “Administration” > “Run Configuration” > Select “Serial Ports, Ethernet, Static Routes” > “Activate Configuration”. If you have open session to a port that you reconfigured, this connection will be closed so you will need to reconnect. Sessions to other unchanged ports will stay untouched.
• To close a session to Serial port: “CAS Sessions” > select one > “Kill Session”. I’ve no idea how to kill all the session at the same time. The easiest way is to use CLI or perform reboot.
• Here is how you can enable multiple simultaneous connections to console ports:
# To allow multiple RW sessions to all the ports with Ctrl+q for menu (which I was not able to simply disable): config configure line 1-48 adminusers 'yes' sniffmode 'i/o' escape '^q' multiplesess 'RW_session' # Activate changes: signal_ras hup # Save the file to the flash: saveconf
• You can also do it using wazard by typing “wiz –snf” or via Web GUI: “Configuration” > “Serial Ports” > All ports > Submit > Sniff Session Mode: Both, Administrative Users: yes, Escape Char from Sniff Mode: ^q, Allows Multiple Sniff Sessions: RW Session, Multiple Sniff Session Notification: no > Submit. Apply/Activate configuration changes by going to “Administration” > “Run Configuration” > Select “Serial Ports, Ethernet, Static Routes” > “Activate Configuration”.
• To connect to a console port you can TELNET to port “7000 + port number”. Based on configuration we just did you should not see any authentication or any menu and should be able to have multiple simultaneous connections to any of console ports.
• To see who is logged in and what port is being used you can use “w” or “w_cas” commands. In this example you can see one remote connection into CLI, one session to console port 1 and 18 sessions to console port 2:

In conclusion I’d like to share my opinion on Cyclades-TS3000:
• It’s very good for personal lab OR for your not really important lab at work especially if you’re on the budget and willing to spend your time to make rollover cables or spend some money on rollover adapters, but make sure it’s behind the firewall (I really don’t want to even try to assess if this ancient device is secure or not).
• For production - NOT recommended since it’s deprecated or simply ancient product with NO support whatsoever. NOT recommended especially if you need to assign public IP to this box or make it accessible from the Internet.
Pros:
• Port density. The “price per port” is low.
• Multiple simultaneous RW connections to a single console port. This is the only major feature that you would be missing if you go with Cisco as AccessServer.
• Web GUI (people like me who prefer CLI won’t care).
Cons:
• You can NOT use regular straight-through ethernet cables and have to make/purchase and run rollover cables OR order rollover adapters that might cost you multiple times more that the price for the chassis itself. Even if the price is $5 per piece overall price for 48 ports is $240.
• NO support.
• Ancient hardware, so your experience most likely will NOT be applicable in your future career which is wasting time. Common things are there (including different options for authentication, logging, PDU integration, etc), but as we all know to make a difference you have to go beyond common things.

MikroTik DHCP server logs to rsyslog [TESTED]
Very quick note on how to configure logging for DHCP server running on MikroTik RouterOS, send and store syslog messages on CentOS 7.x using rsyslog. In our configuration MikroTik device will have 1.1.1.1 IP, CentOS (syslog server) will have 2.2.2.2, we will store syslog messages received from 1.1.1.1 address into /var/log/remotelogs/ folder in a file named “desired_file_name.log”.
MikroTik configuration:
/system logging action set 3 remote=2.2.2.2 /system logging add action=remote topics=dhcp
CentOS 7.x configuration:
[root@centos7 ~]# vi /etc/rsyslog.conf # Provides UDP syslog reception $ModLoad imudp $UDPServerRun 514 # Rules for remote logs if $fromhost-ip=='1.1.1.1' then /var/log/remotelogs/desired_file_name.log & ~
To avoid duplication of syslog messages received from remote host (1.1.1.1) that could appear in default files like “/var/log/messages” you might want to add “stop” (discard action) as it’s mentioned in rsyslog documentation. Here is an example:
[root@centos7 ~]# vi /etc/rsyslog.conf
# Provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514
# Rules for remote logs
if $fromhost-ip=='1.1.1.1' then { action(type="omfile" file="/var/log/remotelogs/desired_file_name.log") stop }
& ~
Then we will need to restart rsyslog service:
[root@centos7 ~]# systemctl restart rsyslog
Then we can generate test log message on MikroTik device:
[admin@MikroTik] > :log info TEST
If our local firewall is not blocking UDP/514 incoming packets you should be able to see that message in target file you specified in configuration:
[root@centos7 ~]# tail -f /var/log/remotelogs/desired_file_name.log | grep TEST 2020-05-25T20:36:20.829911-07:00 host-1-1-1-1.example.com script,info TEST
The last piece is to configure logrotate. I will create a new file in “/etc/logrotate.d/” folder for that:
[root@centos7 ~]# vi /etc/logrotate.d/remotelogs
/var/log/remotelogs/*.log {
# keep 3 versions online
rotate 3
# rotate each day
daily
# compress/nocompress
compress
# add a YYYYMMDD extension instead of a number
dateext
postrotate
/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
endscript
}
You can also forcibly run logrotate to see the result:
[root@centos7 ~]# logrotate -fv /etc/logrotate.d/remotelogs [root@centos7 ~]# ls -lah /var/log/remotelogs/
Good luck!
MikroTik The Dude 6.46.3 or older can not connect to RouterOS 6.46.4 or newer.
I recently had to troubleshoot an issue with “The Dude” v6.46.3 that could not connect to MikroTik v6.46.5. Interestingly enough, target MikroTik devices was showing nothing in its logs (no successful or failed connection attemts). I don’t remember what The Dude was showing, but it was not anything specific that could help to understand what’s wrong like authentication failure.
Captured traffic dump was showing normal TCP session over port 8291 what was active for 30 seconds and then normally terminated by The Dude server. Crazy!
I remember seeing changes regarding Winbox authentication method in some of recent RouterOS release notes. Simple google search showed me this thread - v6.46.4 [stable] is released!:
To get RouterOS data from the devices, Dude now requires RouterOS to be 6.46.4 or newer. The other stats and of course Ping will still work. This is due to security measures being strengthened.
Sure enough, here is what Release notes for 6.46.4 says:
Important note!!!
- The Dude server must be updated to monitor 6.46.4 and v6.47beta30+ RouterOS type devices.
- The Dude client must be manually upgraded after upgrading The Dude server.
- To get RouterOS data from the devices, The Dude now requires RouterOS to be 6.46.4 or v6.47beta30+.
I decided to downgrade MikroTik device to 6.46.3, but it didn’t fully fix the issue. The Dude started showing some specific error:
std failure: not allowed (9), next attempt at 18:35:57
To fix that you have to add “dude” into “full” user group:
/user group set full name=full policy=local,telnet,ssh,ftp,reboot,read,write,policy,test,winbox,password,web,sniff,sensitive,api,romon,dude,tikapp skin=default
Good luck!
