Question about vconsole utility

HI,

 

I have a questions about vconsole utility. I used this command "vconsole guest_name slot_number" to access a guest via console port (PErle appliance). And now when a closed the connection and reconnect, I'm sill connected to the guest. Does anyone know how to come back to the host (hypvervisor) ?

 

No information about this problem on F5 documentation,

 

Thank you,

 

Best regards

    vconsole is basically telnet in disguise, so just send the telnet escape sequence (^]) and then q for quit...

     

    ** Of course if you're TELNET'ed into the host you're vconsoling from that won't work very well, but that should be unlikely as telnet isn't enabled by default on BigIP anyway.

    Use ps to find the process number & kill it as shown below; [root@mybigip:Active:Standalone] config ps | grep tty 10026 ttyS0 Ss 0:00 -bash 10105 ttyS0 S+ 0:00 /usr/bin/telnet 127.3.0.0 22033 14659 pts/0 S+ 0:00 grep ttyS0

     

    [root@mybigip:Active:Standalone] config kill 10105

    I found I have the same problem. I connect to the console of vcmp host and it opens connection to one of the guests instead. Quitting the telnet session quits the whole session, not just the guest session. I do not see a telnet session in the ps output:

    [root@ABC:Standby:In Sync] config  ps | grep tty
 5315 tty1     Ss+    0:00 /sbin/mingetty /dev/tty1
 5339 tty2     Ss+    0:00 /sbin/mingetty /dev/tty2
 5346 tty3     Ss+    0:00 /sbin/mingetty /dev/tty3
 5356 tty4     Ss+    0:00 /sbin/mingetty /dev/tty4
 5384 tty5     Ss+    0:00 /sbin/mingetty /dev/tty5
 5435 tty6     Ss+    0:00 /sbin/mingetty /dev/tty6
15340 ttyS0    Ss     0:00 -bash
15971 ttyS0    S+     0:00 -bash
15972 ttyS0    S+     0:00 grep tty
15974 ttyS0    R+     0:00 /bin/ps ax

    Any other idea how to disconnect from the guest and get back to the host?

    Thank you for any advice,

    Regards
