Console Port
Jul 20, 2009
I've noticed on some rackmount servers and firewall appliances there are ports labelled console, and look like serial ports. Are these related to connecting to KVM? I am looking for a cheap appliance for some rackmount servers I have (1U half depth would be ideal), to remotely recover the server if it goes down. I figured they'd connect through PS2 connectors, but then I thought that if the console port was related, then going through that might have the option for power cycling or something.

I'm trying to knock a bug out of our new Hardy Heron Xen template. Basically when the old ones boot up /bin/sh is spawned on the console. Now with Hardy init has been replace with /etc/event.d handling.
So I've replace /etc/event.d/ttyS0 and ttyS1 (not sure which one is the console but I think ttyS0)
Code:
# tty0 - shell
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.
start on stopped rc2
start on stopped rc3
start on stopped rc4
start on stopped rc5
stop on runlevel 0
stop on runlevel 1
stop on runlevel 6
exec /bin/bash
respawn

I am upgrading my current colo'd server from a 1U dual core xeon with 2x500GB drives to a 2U core 2 quad with 8x750GB drives (raid5).So far I have ran into two issues. One is the rails are too large for the cabinets (problem #1 which I put in another thread). The only other problem is I am having problems with remote console on the new hardware.
It should be setup correctly since I basically rsync'd everything from the old server to the new one. The device is detected:
root@houkouonchi: 03:19 AM :~# dmesg | grep -i tty
Command line: root=/dev/sda2 gpt pci=nomsi console=tty0 console=ttyS0,9600 notsc
Kernel command line: root=/dev/sda2 gpt pci=nomsi console=tty0 console=ttyS0,9600 notsc
console [tty0] enabled
console [ttyS0] enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:05: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
But when I connect to the digi I am not getting any console output. I have tried a different serial -> Ethernet adapter and tried a different patch cable/port on the digi so I am pretty sure those are fine. The motherboard (nforce 650i chipset) didn't have an onboard serial port so I am using a port hooked up to a bracket which has a ribbon cable which connects to the motherboards COM port. I also tested another serial connector which the case has built in and both give me problems.
Maybe the motherboard is just busted?

What type of cable/settings are needed to access the console port of a ProCurve 2626 J4900A? the recent one I ordered wasnt working with the regular way I access these switches.
I use a null modem (crossover) female-female serial console cable and connect it to my laptop serial port w/9600-8-1-None to access my ProCurve 2900 48G series.
But I tried using a straight/null/rollover(cisco's) and none of them worked. I also tried 9800-8-1-xoff/xon. All of them are giving me weird text when I press [ENTER] numerous times. I can access my 2900 series switches fine, no problem, just these 2626 ones I cant. My laptop can definitely detect the port cause when I disable it, I get a message on my terminal window which says "disconnected". So I am messing up somewhere.
By the way, I actually returned the switch when it came the first time because I thought they gave me a faulty one and I got another one, but it behaves the same way. But the actual switch functionality has no issues as I can assign my servers IPs and be able to access them remotely. I just cant configure the switch itself without the console port.

I have a SuperMicro server with AOC-SIM1U.
I was able to login from IPMI View just fine, and everything works as expected except
"Text Console ". I was able to hit the start button and get the black screen on IPMI View, but that was just about it.
Only a cursor blinking without texts.
Is there something else that I should do in order to get text console working? I've tried all baud rates.

We have a windows 2003 machine that is currently responding properly to all services that it's running (including IIS and FTP), however RDP connections just close right away and the server isn't responding when a local keyboard & monitor is plugged in.
The last thing that I want to do is pull the power out while it's on - any ideas?
I tried a remote shutdown, but the response is:
C:Users>shutdown /r /m HOSTNAME
HOSTNAME: The entered computer name is not valid or remote shutdown is not supported on the target computer. Check the name and then try again or contact your system administrator.(53)

When you can't access your server via SSH or Remote Desktop, what do you use to fix the problem without filing a ticket?
IPMI?
Serial console?
KVM over IP?
Dial up connection?
Backup network connection?
Get up and walk to the server? :-)
If you had a choice between them, what did you pick and why?
Does your dedicated server provider give it to you for free, or do you have to pay extra for it?

Since some days I have the strange issue that all logings from DrWeb is shown directly into the console. For example if I connect to my Server via SSH and then I sned an email to my email accoutn I see the logging of the spool.
root@************:~# 2015 Mar 25 16:44:57 * 127.0.0.1 [13727] /var/spool/drweb/spool/drweb.tmp.tWcneM - archive MAIL
2015 Mar 25 16:44:57 * 127.0.0.1 [13727] >/var/spool/drweb/spool/drweb.tmp.tWcneM/3.part - Ok
2015 Mar 25 16:44:57 * 127.0.0.1 [13727] >/var/spool/drweb/spool/drweb.tmp.tWcneM/4.part - Ok
2015 Mar 25 16:44:57 * 127.0.0.1 [13727] >/var/spool/drweb/spool/drweb.tmp.tWcneM/5.reexport - Ok
2015 Mar 25 16:44:57 * 127.0.0.1 [13727] /var/spool/drweb/spool/drweb.tmp.tWcneM - Ok
this happens in my root shell. if I disable the Email check then this will not happen anymore. another strange issue is that if I restart drweb and I have more than 1 ssh shell open I see the output of the restart on all shells, this issue is only for drweb not for any other service. How to config drweb to log only into logfile not to the console?
I search the web and the only thing I can find was
[URL]
In the FreeBSD operating system, syslog service can intercept information output by Dr.Web Daemon to the console. In this case, the information is logged character-by-character. That occurs when the logging level is set to *.info in the syslog configuration file (syslog.conf).

I have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
How can I keep my connection/port number ...?

I am using proftpd...How do i instruct that the server don't listen on high ports 49152-65534 but only to 21?
The reason is because my client's firewall setup is very strict and i need to give a good reason to open those high ports. Right now, i can ftp to port 21 only but can't do nothing more than that coz the higher ports are blocked.

i now have root access at a site i manage and the previous admin has set up a different SSH port.
I think this because i get " Connection Refused " and that user has access for SSH.
When restarting my SSH services i recive;
Quote:
sshd has failed, please contact the sysadmin.
And from looking that error up it means the port has been changed.
So i have WHMC access and all other root passwords etc, but how can i find out the port?

I know this is a bit of an odd question but I have a VPS which has port 1189 open. Is it normal by default to have this port listening on a OpenVZ VPS under HyperVM? or is this something a little concerning? Never noticed it before, just checking I don't want any illegal applications being hosted on my server by clients.
It's most probably nothing to be concerned about, just wanted to double check.
