Mitigating Poodle SSLv3 vulnerability

New vulneranility was announced in archaic SSLv3 protocol. You can defend your server by disabling usage of SSLv3 protocol. But take in mind that according to rumors Windows XP with IE6 still use it to, so basically disabling SSLv3 means cutting off old WinXP users from your services

On the bottom of page you can also find tips to disable SSLv3 in Firefox and Chrome

 

Disabling SSLv3

apache

Add/modify line in /etc/httpd/conf.d/ssl.conf so it looks like this:

SSLProtocol all -SSLv2 -SSLv3

restart apache:

service httpd restart

postfix

Add to file /etc/postfix/main.cf:

smtpd_tls_mandatory_protocols=!SSLv2,!SSLv3

restart postfix

service postfix restart

dovecot  before v2.1

to get dovecot version use:

[root@vps dovecot]# dovecot --version
2.0.9

File /etc/dovecot/conf.d/10-ssl.conf
add/modify line

ssl_cipher_list = ALL:!LOW:!SSLv2:!SSLv3

dovecot v 2.1 and newer

File /etc/dovecot/dovecot.conf add/modify line :

ssl_protocols = !SSLv2 !SSLv3

restart dovecot:

service dovecot restart

 

 Firefox

in URL line, type about:config, search for security.tls.version.min and set value to 1

 

Chrome

Unlike in FF you can't set it permanantly somewhere in configuration, so you have to start Chrome everytime with parameter –ssl-version-min=tls1

Bash tips

How to convert string to array of strings

#1st declare our separator
IFS=";"
#define our string we want to split
NAMES="Linus Benedict Torvalds;James Bond;Franta Novak"
#try this one:
AR_N=($NAMES)
#OR this one (if previous not working):
read -a AR_N <<<"$NAMES"
#remove our previously defined separator
unset IFS

variable AR_N not contains our separated strings, 1st item in array is AR_N[0]


Convert small letters to big ones

echo abcd | tr [:lower:] [:upper:]

Convert hexadecimal number to decimal

echo "ibase=16; `echo 2f194| tr [:lower:] [:upper:]`" | bc

 

VIM editor

vim editor is very popular among linux/unix admins. On of cool feature is syntax highlighting. Did u know what you can disable this highlighting or change color scheme ?

To enable/disable syntax highlighting  type:

:syntax on/off

To change color cheme in vim :

:colo SCHEME

where SCHEME can be eg. delek, desert, morning

To make this options permanent just create/modify file "~/.vimrc" eg

colo desert
syntax on

AIX tips

Adding user to group

please take in mind that in AIX u cant add new group to existing ones by single command/parameter like in RHEL/SUSE, so be carefull using -G parameter

USER=jamesbond; NEWGROUP=wheel; usermod -G `id -nG $USER | tr " " ","`,$NEWGROUP $USER

Extending FS on AIX

1) we are interrested in mountpoint /sapmnt/sap
2) we need to know volume name => volume name is lv4
3) lslv lv4 -> i need to find volume group name => d4dvg
4) lsvg d4dvg => we need to know available free space we can use for extending "FREE PPs:"
5) ok, we can extend for maximum of 1GB: chfs -a size=+1G <mount point>

Sometimes attempt to extend FS failes because number of LPs is approaching to MAX LPs:

EACH LP COPY ON A SEPARATE PV ?: yes                                   
Serialize IO ?:     NO    

if this is the issue we can increase MAX LPs

chlv -x 3000 <log.vol>

and then we can try to extend FS again

Check if all mountpoints are in read-write mode

If you work with servers  that use SAN storages yo uprobably know this scenario – one or more paths got temporarily offline. After all paths are online again you need to be sure that all filesystems are accessible and are still in read-write mode. You can easily check it using commands below:
 

Linux

FILE=readwrite.check; for i in `mount | awk ' $5!~/(proc|sysfs|devpts|tmpfs|debugfs|usbfs|subfs|binfmt_misc|rpc_pipefs|nfsd|vxodmfs|securityfs|fusectl|oracleasmfs)/ {print $3}'`; do echo "======== $i ========"; echo "Objects in folder: $(ls -la $i | wc -l)"; echo "rw check" > $i/$FILE; ls -la $i/$FILE; rm -f $i/$FILE; echo; done;
 

AIX

FILE=readwrite.check; for i in `mount | awk '$3 !~/procfs/ {print $2}'`; do echo "======== $i ========"; echo "Objects in folder: $(ls -la $i | wc -l)"; echo "rw check" > $i/$FILE; ls -la $i/$FILE; rm -f $i/$FILE; echo; done
 

Solaris

FILE=readwrite.check; for i in `mount | awk ' $3!~/(fd|ctfs|sharefs|objfs|mnttab|devices|proc|sharetab)/ {print $1}'`; do echo "======== $i ========"; echo "Objects in folder: $(ls -la $i | wc -l)"; echo "rw check" > $i/$FILE; ls -la $i/$FILE; rm -f $i/$FILE; echo; done
 

MKC Q&A

  1. I don’t like default colors, can I change it?

    Sure, in fact MKC is one of most customizable file managers / commanders
    You can either customize colors 1) individually or 2) using themes

    Simplest way is 2) so:
    in MKC press software or hardware MENU button -> item Config – Configuration will appear. Here choose General Tab on left and 7th item on right should be Theme. Theme config will appear, here choose eg Dialogs Theme -> Dark and Font Theme -> “White-based Lighter”. Press OK, you will return to Configuration. At the bottom press ‘Restart MKC

  2. Where do I find MKC logfile ?

    MKC saves it’s log file to SD card, so basically it can be as bellow:
    /sdcard/Android/data/cz.raven4/MKCommander_HD/logs/log.txt
    /sdcard/Android/data/cz.raven4/MKCommander1/logs/log.txtPlease just take in mind that on different devices, SD card can have different name, so path can start like this instead :
    /external_sd/Android/….

  3. MKC says it is outdated and I have to download latest versions

    I implemented this feature because some people were using very very old versions, complained about bugs / reported bugs that were already fixed in newer versions

  4. Whats difference between MKC HD and MKC ?

    Basic point was simplicity and simple UI for MKC and powerful full featured manager for MKC HD. I’m continuing in making MKC (non HD) more simple to use, optimize it for really begginer-users
    It’s needed to mention that both applications share same code, which detects package name (cz.raven4.MKCommander1 vs …MKCommander_HD) during 1st start and makes some optimizations

  5. Are MKC settings stored securely ? I mean eg my bookmarks, logon credentials to FTP / Samba

    Sure! basic settings like colors and so on are stored in plaintext. BUT any private information like bookmarks, logon credentials ARE encrypted with AES

  6. Why do I have to see Ads (advertisements) ? How to get rid of them?

    Initially MKC was developed as free software completely. Those who appreciated my work could send me some donation via Donation app voluntarily. However, after some time there were thousands of users worldwide but number of donations were almost zero. I already spend 1000+ hours on development so I had to decide. Either stop any MKC development and focus on some activity to earn some money elsewhere or I had to change MKC model
    So now MKC is Ads-supported software and sure you can get rid of Ads simply, just buy Donation app from Play, install it and leave in device

  7. MKC is not translated in my native language. Can I help to translate it?

    Sure! Just email me to mkc@raven4.cz
    I’ll very appreciate your help in translating MKC to many foreign language
