SOLVED: SSH and Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password) http://froebe.net/blog/2016/09/15/solved-ssh-and-permission-denied-publickeygssapi-keyexgssapi-with-micpassword/ http://froebe.net/blog/2016/09/15/solved-ssh-and-permission-denied-publickeygssapi-keyexgssapi-with-micpassword/#respond Thu, 15 Sep 2016 21:01:48 +0000 http://froebe.net/blog/?p=3353 OpenSSHI ran across the error “Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).” while ssh’ing to another server today:

$ ssh myhost
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Usually this means that the permissions of ~/.ssh, ~/.ssh/authorized_keys or your home directory on the other box isn’t setup right The permissions should look like so:

  1. -rwx——. /home/jason
  2. -rwx——. /home/jason/.ssh
  3. -rw——-. /home/jason/.authorized_keys

You would fix with:

$ chmod 0700 ~
$ chmod 0700 ~/.ssh
$ chmod 0600 ~/.ssh/authorized_keys

In my case, the permissions were correct. I ran the ssh command with extra verbose (-v -v)

Permission denied (publickey,password,keyboard-interactive).

I didn’t see a reason why I wasn’t getting a password prompt but I do see it reading my ssh_config file. A real quick override of the ssh_config showed me that my ssh_config was the culprit:

$ ssh -F /dev/null myhost
jason@myhost's password:

So what is in my ~/.ssh/config file?

ServerAliveInterval 240
BatchMode yes
TCPKeepAlive = yes

Neither ServerAliveInterval or TCPKeepAlive have anything to do with authentication but BatchMode does. From the ssh_config man page:

BatchMode

The argument must be yes or no. If set to yes, passphrase/password querying will be disabled. This option is useful in scripts and other batch jobs where you have no user to supply the password.

So, if my public ssh key is not in the ~/.ssh/authorized_keys, the connection will fail with a permission denied. Let’s verify but removing BatchMode from the ~/.ssh/config file:

ServerAliveInterval 240
TCPKeepAlive = yes
$ ssh -F /dev/null myhost
___$

Success 🙂

OpenVPN & Network Manager: selecting a random VPN target each time you start the Virtual Private Network (UNIX/Linux) SOLVED http://froebe.net/blog/2016/08/26/openvpn-network-manager-selecting-a-random-vpn-target-each-time-you-start-the-virtual-private-network-unixlinux-solved/ http://froebe.net/blog/2016/08/26/openvpn-network-manager-selecting-a-random-vpn-target-each-time-you-start-the-virtual-private-network-unixlinux-solved/#respond Fri, 26 Aug 2016 13:17:22 +0000 http://froebe.net/blog/?p=3346 I sometimes perform some IT work for a nonprofit organization. They use OpenVPN for their network but since they reside in different locations, they have multiple OpenVPN servers set up rather than just one point of entry. The problem I’ve noticed is that at times one or another will be slower. While I don’t have a mechanism to identify which is faster, I can roll the dice and have my vpn start script pick a random server instead of me having to randomly pick one myself.

#!/bin/bash

# If the network card is unavailable, we're not going to bring up the vpn
REQUIRED_CONNECTION_NAME="enp0s8"

# VPN_LIST is just a simple array
declare -a VPN_LIST

# BASH arrays start with index 0
i=0

# read the vpn list into an array
while read TMP_VPN; do
    VPN_LIST[$i]="$TMP_VPN"
    ((i++))
done < vpns.txt 

# if the vpns.txt is NOT empty
if (( i >= 0 )); then
    # Choose a random VPN index from the TMP_VPN array
    if (( i > 0 )); then
        ((i - 1))
        ((RANDOM_VPN = $RANDOM % $i))
    else
        RANDOM_VPN=$i
    fi

    # We set the VPN_CONNECTION_NAME to the VPN we chose
    VPN_CONNECTION_NAME=${VPN_LIST[$RANDOM_VPN]}

    DEFAULT_CONNECTION=$( nmcli con show --active |grep "${REQUIRED_CONNECTION_NAME}" )
    VPN_CONNECTION=$( nmcli con show --active | grep "${VPN_CONNECTION_NAME}" )

    # Make sure that the vpn connection isn't already up
    if [[ "${DEFAULT_CONNECTION}" != "${VPN_CONNECTION}" ]]; then
        echo -n "Connecting to ${VPN_CONNECTION_NAME} ... "

        # The credentials are stored in my Gnome keyring so I run the nmcli command as jason
        su - jason -c "nmcli con up id \"${VPN_CONNECTION_NAME}\""

        RC=$?

        if (( RC == 0 )); then
            echo "SUCCESS"
        else
            echo "FAILED"
        fi
    else
        echo "configuration mismatch"
        RC=1
    fi
fi

exit $RC

The file vpns.txt is simply a text file with the names of the VPNs as they are listed in OpenVPN (see /etc/NetworkManager/system-connections for the list of defined VPNs). One VPN per line.

Krav Maga at Victory Martial Arts of Okemos http://froebe.net/blog/2016/08/24/krav-maga-at-victory-martial-arts-of-okemos/ http://froebe.net/blog/2016/08/24/krav-maga-at-victory-martial-arts-of-okemos/#respond Wed, 24 Aug 2016 18:12:37 +0000 http://froebe.net/blog/?p=3341 Krav Maga according to Wikipedia:

Krav Maga /krɑːv məˈɡɑː/ (Hebrew: קְרַב מַגָּע [ˈkʁav maˈɡa], lit. “contact-combat”) Victory Martial Arts of Okemosis a self-defense system developed for the Israel Defense Forces (IDF) that consists of a wide combination of techniques sourced from aikido, judo, boxing and wrestling, along with realistic fight training. (Unlike MMA) Krav Maga is known for its focus on real-world situations and its extremely efficient and brutal counter-attacks. It was derived from street-fighting skills developed by Hungarian-Israeli martial artist Imi Lichtenfeld, who made use of his training as a boxer and wrestler as a means of defending the Jewish quarter against fascist groups in Bratislava, Czechoslovakia in the mid-to-late 1930s. In the late 1940s, following his migration to Israel, he began to provide lessons on combat training to what was to become the IDF, who went on to develop the system that became known as Krav Maga. It has since been refined for civilian, police and military applications.

Krav Maga has a philosophy emphasizing threat neutralization, simultaneous defensive and offensive maneuvers, and aggression. Krav Maga has been used mainly by the Israel Defense Forces’

special units and reconnaissance brigades and recently by regular infantry brigades, and several closely related variations have been developed and adopted by law enforcement and intelligence organizations, Mossad and Shin Bet. There are several organizations teaching variations of Krav Maga internationally.

Windows 10: Touch Screen not working? Solved! http://froebe.net/blog/2016/07/24/windows-10-touch-screen-stopped-working-solved/ http://froebe.net/blog/2016/07/24/windows-10-touch-screen-stopped-working-solved/#respond Mon, 25 Jul 2016 01:40:00 +0000 http://froebe.net/blog/?p=3292 I have a Toshiba laptop running Microsoft Windows 10. I’ve recently reinstalled the operating system and noticed that the touch screen stopped working. I searched high and low looking for an answer but didn’t find one that would work.

Microsoft recommends the following but it didn’t help me:

  1. Re-start your PC.
  2. Wipe it off. Use a microfiber cloth if possible.
  3. Search Calibrate the screen for pen or touch input from the task bar and select the top result. Hit the Setup button and follow the prompts.
  4. Search Device manager from the task bar and select the top result. Select Monitors and right click on the name of your monitor. If one of the menu items is enable, choose that.
  5. Repeat process number four above, but this time choose Update driver software from the right-click menu.

It was, however, quite close to what I discovered was thedevicemanager problem.   If I went into Device Manager (Windows Key + X and choose Device Manager) and Disabled/Enabled the HID-compliant touch screen device the touch screen would work for a few minutes and then suddenly stop working again.

After scratching my thinning hair on top of my head, it dawned on me that it was probably power management related.  I looked in the Power Management tab for the device but the option was disabled.

Sodevicemanager2 what to look at next?  All of the Human Interface Devices run as USB devices.

Looking at the Universal Serial Bus Controllers I saw that several of the devicemanager3USB Hubs and such did have the Allow the computer to turn off this device to save power option set.
I unchecked the option and disabled/enabled the HID-compliant touch screen device and Voila! the touch screen worked!  It’s been several hours now and the touch screen is still working fine.

HOWTO: Connect to SAP Sybase IQ Multiplex using JDBC and the SQL Anywhere driver: “Connection error: TCPIP requires a server name” http://froebe.net/blog/2016/03/16/howto-connect-to-sap-sybase-iq-multiplex-using-jdbc-and-the-sql-anywhere-driver-connection-error-tcpip-requires-a-server-name/ http://froebe.net/blog/2016/03/16/howto-connect-to-sap-sybase-iq-multiplex-using-jdbc-and-the-sql-anywhere-driver-connection-error-tcpip-requires-a-server-name/#comments Wed, 16 Mar 2016 15:44:54 +0000 http://froebe.net/blog/?p=3267 SAP’s documentation, like other vendors, often sucks. In today’s wonderful documentation sucky-ness the examples from SAP to connect to IQ using a JDBC connection string like so:

“jdbc:sqlanywhere:UID=***;ENG=MyIQ;PWD=***;links=tcpip(Host=MyIQ;PORT=40000)”

This is fine except when you connect to IQ multiplex and you have logical servers set up. You won’t know which IQ node you will be on and since each IQ node has an unique name (eng=), this won’t work. Alright, let’s drop the eng=MyIQ.

“jdbc:sqlanywhere:UID=***;PWD=***;links=tcpip(Host=MyIQ;PORT=40000)”

This will result in an immediate error of “Connection error: TCPIP requires a server name”. Don’t panic, there is a fix. Drop the ENG=MyIQ and links=tcpip(Host=MyIQ;PORT=40000) replacing it with the HOST=MyIQ:40000.

“jdbc:sqlanywhere:UID=***;PWD=***;HOST=MyIQ:40000)”

That works. That is so much more simple than the demented links=tcpip(Host=MyIQ;PORT=40000) nonsense.

Now the fun bit of working code. The following “IQConnect” program accepts four parameters host port username password and spits out the names of the tables on the IQ server:

import java.io.*;
import java.sql.*;

public class IQConnect {
    public static void main(String[] args) {
        if (args.length == 4) {
            String HostName;
            int Port = 0;
            String UserName;
            String Password;

            try {
                Port = Integer.parseInt(args[1]);
            } catch (NumberFormatException e) {
                System.err.println("Port # must be an integer");
                System.exit(1);
            }

            HostName = args[0];
            UserName = args[2];
            Password = args[3];

            String arg;
            Connection con;

            try {
                String ConnectionParams = String.format("jdbc:sqlanywhere:uid=%s;pwd=%s;host=%s:%d", UserName, Password, HostName, Port);
                con = DriverManager.getConnection(ConnectionParams);

                Statement stmt = con.createStatement();
                ResultSet rs = stmt.executeQuery("select table_name from sys.systable;");

                while (rs.next()) {
                    String TableName = rs.getString(1);
                    System.out.println(TableName);
                }

                stmt.close();
                con.close();
            }
            catch (SQLException sqe)
            {
                System.out.println("Unexpected exception : " +
                  sqe.toString() + ", sqlstate = " +
                  sqe.getSQLState());
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
        } else {
            System.out.println("Requires Host Port# User Password");
        }
    }
}

Compile it with:

javac -cp $IQ16/java/sajdbc4.jar:. IQConnect.java

Execute it with

java -cp $IQ16/java/sajdbc4.jar:. IQConnect MyIQ 40000 dba sql

Of course, if you have $IQ16/java as part of your $CLASSPATH you don’t need to include “-cp $IQ16/java/sajdbc4.jar:.” to execute the program.

HOWTO: Korn Shell / BASH: How to determine if a string is numeric or not http://froebe.net/blog/2016/02/18/howto-korn-shell-bash-how-to-determine-if-a-string-is-numeric-or-not/ http://froebe.net/blog/2016/02/18/howto-korn-shell-bash-how-to-determine-if-a-string-is-numeric-or-not/#comments Thu, 18 Feb 2016 21:27:41 +0000 http://froebe.net/blog/?p=3245 Occasionally we run across something that should be simple. Checking whether a string is a number or not for example.

special_CHAR ‘(‘ pattern ‘)’

The special_CHAR is a prefix that changes the number of characters expected:

‘*’ for zero or more matches
‘+’ at least one match
‘@’ for exactly one match
‘?’ for zero or one matches
‘!’ for negation

The following will match one or more digits:

+([[:digit:]])

See POSIX Character Classes regarding the use of [:digit:]

Below is an example function to determine if a string is numeric written in Korn Shell 93 but will also work in BASH.

The criteria we’re using is based on the US standard of numbers:
1
12.345
and so on

Obviously we could expand this out to handle commas or other separators without too much difficulty.

#!/bin/ksh93

function is_numeric {
    typeset TMP_STR="$1"
    typeset -i TMP_IS_NUMERIC

    if [[ "$TMP_STR" == +([[:digit:]])?(.*([[:digit:]])) ]]; then
        echo "'$TMP_STR' is numeric"
        TMP_IS_NUMERIC=1
    else
        echo "'$TMP_STR' is not numeric"
        TMP_IS_NUMERIC=0
    fi

}

for TMP_STRING in "TEST_VAR" "22" "TRUE1" "TRUE3TRUE" "12.345" "7.8.9.0"; do
    is_numeric "$TMP_STRING"
done

OUTPUT:

$ ./test_regex.ksh
'TEST_VAR' is not numeric
'22' is numeric
'TRUE1' is not numeric
'TRUE3TRUE' is not numeric
'12.345' is numeric
'7.8.9.0' is not numeric

See Finnbarr P. Murphy’s blog for more examples of using regular expressions in Korn Shell 93

If you don’t drink, you will wish you do. (Just like with any other cluster system)

In my latest foray into the murky waters of IQ Multiplex (v16), if one of the nodes if offline for a while, the coodinator node will mark the node as excluded so the cluster carries on. Not really a big deal until you try to bring up the problem node:

I. 02/09 10:31:45. Database server stopped at Tue Feb 09 2016 10:31

iq_node_2          included writer           active
iq_node_3          excluded unknown           timed_out

As you can see, the iq_node_3 node is excluded due to the connection to it from the coordinator timed out. What to do? Simple, first we re-include the node (on the coordinator):

alter multiplex server iq_node_3 status included;

Next we need to resync iq_node_3:

Resync IQ secondary node

The problem node should start up just fine now.

Database "/siq/devices/myiq.db" not created

Unfortunately there is no way to specify the IQ temp cache size via the iqinit program:

Usage: iqinit [options] database
        @data expands data from environment variable data or file data

Options (use specified case, as shown):
        -a             accent sensitivity on all UCA string comparisons
        -af            accent sensitivity (French rules) on all
                       UCA string comparisons
        -b             blank padding of strings for comparisons
        -c             case sensitivity on all string comparisons
        -dba uid,pwd set dba username and password
        -dbs size    set initial database size
        -ea alg      encryption algorithm (default none)
        -ek key      specify encryption key
        -ep            prompt for encryption key
        -et            enable encrypted tables
        -i             do not install jConnect support
        -k             SYS.SYSCOLUMNS and SYS.SYSINDEXES views not created
        -l             list available collation sequences
                       (use -l+ to list older collations)
        -le            list available character set encoding labels
                       (use -le+ to list more encoding label aliases)
        -m name      set transaction log mirror name
        -n             no transaction log
        -o file      log output messages to file
        -p size      set page size (must be power of 2 = 2048 and = 32768)
        -pd            legacy system stored procedure behavior
        -q             quiet: do not display messages
        -s             add checksum to database pages
                       (by default checksums are added to database pages,
                       use '-s-' to turn off adding checksums to database pages)
        -t name      transaction log file name (default is database.log)
        -z coll      specify collation sequence for CHAR data type (defaults
                       to server platform's codepage and ordering)
        -ze encoding specify character set encoding for CHAR data type
        -zn coll     specify collation sequence for NCHAR data type
                       (use '-zn UTF8BIN' if the ICU libraries are not
                       available on the server that will load the database. ICU
                       libraries might not be installed on some platforms, such
                       as Windows CE.)
        -iqpath        The path name of the main segment file containing the
                       IQ data.
        -iqsize        The size in MB of either raw partition or OS file with
                       the -iqpath.
        -iqpgsize      The page size in bytes for the Sybase IQ segment of the
                       database.
        -iqblksize     The I/O transfer block size in bytes..
        -iqreservesize Specifies the size in MB of the space to reserve for
                       the Main IQ store.
        -iqmsgpath     The path name of the segment containing the Sybase IQ
                       message trace file.
        -iqtmppath     The path name of of the temporary segment file.
        -iqtmpsize     The size in MB of either the raw partition or OS file
                       for the -iqtmppath.
        -iqtmpreservesize     The size in MB of space to reserve for the
                        temporary IQ store.

Since iqinit calls the iqsrv16 program, we can rename the iqsrv16 to iqsrv16.orig and wrap it with the following iqsrv16 shell script:

#!/bin/ksh

$SYBASE/IQ-16_0/bin64/iqsrv16.orig -iqtc 200 -iqmc 200 $*

Note that I’m allocating 200mb of both main and temporary cache. The IQ instance is now able to start and once the database is created, we can simply replace the iqsrv16 wrapper with the iqsrv16.orig program.
