2161DS's Serial Port Not Responding
May 21, 2007
I got my hands on a used 2161DS (unit only, no cables etc), but somehow it doesnt seem to respond on the hyperterminal to any keyboard input.
As its used it doesnt have any support directly from Dell and Dell is unable even to give us a cost estimate as the service tag number is not in their system. Anyway...
When I power up the 2161DS KVM-Over-IP switch all I get in the Hyperterminal is
---
Verifying subsystem flash versions...
<snip>
DELL 2161DS Console Ready...
Press any key to continue
---
From there on its not working. The keyboard and mouse directly connected to it are working. Also all the menus, but we can set the network address, do firmware updates etc, only from the serial port connection (once the serial port is working).
I checked the hyperterminal settings (9600 baud, 8 bit, 1 stop bit, no parity, no flow control).
Is there anything that I might be missing?
Perhaps I have to use something like a crossed serial cable instead of a straight one ?
Character set issues?
Terminal type issues?
We have spent days in front of the machine and on the phone with Dell without really getting anywhere. Its our first 2161DS so I still want to believe that we must be missing something.

Since 15.05.2015 smtp experiencing problems.
Smtp service (qmail) stops responding on port 25:
# time telnet localhost 25
Trying 127.0.0.1...
quit
quit
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
quit
quit
Connection closed by foreign host.
real 4m10.629s
user 0m0.000s
sys 0m0.002s
After server restart or sometimes apache stop or ixnetd restart its responding for a some random time, and then again it stops to respond. Plesk panel show it as stopped but qmail itself running in memory, and does other its work, it just stops responding at port 25, or responds with a huge delay.
I've tried change it to postfix, reconfigured with mchk, repaired with repair.sh -r, disabled and uninstalled parallels antivirus, antispam, dnsbl, disabled firewall, disabled smtp lock. Checked apache, dns. Enabled submission port which works when 25 port doesnt, but i need working 25 port.
Nothing solves problem, its just stops responding after some random time. There is no errors on maillog.
I think this problem occured after recent plesk microupdate, because i didn't do anything to server configuration in last months.
This article says it might be dnsbl [URL] .... but it disabled(from plesk panel) on my server, maybe there is way to focefully kill any relation to dnsbl?
Plesk info:
OS Red Hat Enterprise Linux Server 5.9 (Tikanga)
Panel version 11.5.30 Update #50, last updated at May 18, 2015 05:21 PM
The system is up-to-date; last checked at May 17, 2015 10:56 PM
update: xinetd restart is definitely brings smtp alive, but it goes off after random period of time (5min ~ couple hours)

We have 2 Cisco PIX 515's in a failover configuration (7.1 series IOS). We have available both a serial failover cable and adequate switch capacity to allow using either the serial or LAN-based approach. We have no current plans to locate the firewalls physically apart.
We have plenty of info on how to configure either, but no recommendation on which is the better choice.

SOA Serial
SOA REFRESH
SOA RETRY
SOA EXPIRE
SOA MINIMUM TTL
This are all items of DNS and by default set that :
SOA Serial= 0
PassSOA REFRESH= 10800. That is OK
PassSOA RETRY = 3600. Looks ok
PassSOA EXPIRE = 604800.Looks ok
PassSOA MINIMUM TTL= 10800 is OK (RFC2308 recommends a value of 1-3 hours)
SOA Serial always is set to 0 and this is a wrong setting.

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?

I have one domain (just one?) that has a serial of 0 (on my server 5.9.57.170 , latest plesk)
Because of that, dns updates don't happen, dns servers don't respond , and my domain issuer is threatening to revoke the domain as it is not working as it should.
> dig auringostaitaan.fi @5.9.57.170 soa +short
robotns3.second-ns.com. torsten.ruger.gmail.com. 0 10800 3600 604800 10800
You can see the test here [URL] .... when you enter the domain auringostaitaan.fi
In trying to fix this i have switched the dns off,changed the mode, enabled RIPE, but i get what it says [URL] ....
Note: See the sample of SOA serial number generated with the selected format. If the resulting number is less, than the current zone number, the modification may cause temporary malfunction of DNS for this domain. Zone updates may be invisible to Internet users for some time.

there are many online tools to check the health of our servers, domains, smtp services, etc.

i'm unable to the response times of my server. The server resolves the correct ip to the ping domain but gets a request timed out.

a pretty weird problem is happening on one server
# ps -auxw | grep exim
mailnull 538 0.0 0.4 5448 2044 ?? Ss 7:16AM 0:00.01 /usr/local/sbin/exim -bd -q30m (exim-4.64-0)
mailnull 1568 0.0 0.4 5448 2048 ?? S 7:22AM 0:00.00 /usr/local/sbin/exim -bd -q30m (exim-4.64-0)
# telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to localhost
Escape character is '^]'.
and nothing else... I don't get the EXIM banner, so many things are not working
mainlog or rejectlog says nothing about that...
mainlog just says everything is ok after I restart it:
exim 4.64 daemon started: pid=1664, -q30m, listening for SMTP on port 25 (IPv6 and IPv4)
I find it strange too that sockstat and netstat doesn't show anything about the smtp server (this is running FreeBSD):
# sockstat -4 | grep 25
# netstat -an | grep 25
# sockstat -4 | grep -i smtp
# netstat -an | grep -i smtp
#
I tried to use the default config and got the same error

I have a very strange problem. Yesterday morning I got a "server down" alert. Restarted httpd and everything run ok ... until today morning, the same problem again.
Symptoms:
1. The webserver did not stop working, it just took too much time to respond.
2. I cannot find anything suspicious in the logs.
3. I started to log the number of apache processes in 4 minutes interval, it did not increase during the failure but remained at a very reasonable number.
4. Now, almost 3 hrs from the last failure, there are 36 apache processes, each eating 14M RAM, server has 4GB ram total, no swapping, almost 3GB are free (cached).
The question is.
How should I prepare for the expected tommorow failure, to be able finaly localise the problem?

I have 3 servers ServerA(Web, mail), ServerB(MySQL+Master replication), ServerC(Mysqlslave+web)
It happens that my website stops responding for few mins and then it comes back again automatically. I checked the server logs but I couldn't find any suspicious.
Also, while the website is not accessible when I try to connect internally from ServerC to ServerA or ServerB using SSH. It takes lots of time (approx more than 60 seconds) to connect. When website starts working SSH is also working fine.
This is very complicated for me. Can anyone let me know what should be the problem or how can I find root cause of this problem?

it has been over 36 hours since I submit a ticket to GixxerPC because I can't login to my client account and I want to cancel my VPS.
I guess they have decided to close their doors to me once I asked for a cancellation because a friend of mine is letting me use his VPS.
I am hoping that this topic will catch the eyes of some GixxerPC staff so they will answer my ticket.

recently I have update our Apache 2.2 instance to 2.4.10, and started using Apache in Windows 2008 R2 64 bit (before we were using it in Win 2003). Our Apache is used mainly as reverse proxy to 3 apps. Well, it seems that, even if I have scheduled a nightly reboot of its service, every day it hangs, becoming unresponsive and forcing us to restart it to make it work again.

ThePlanet not responding to a ticket for nearly a week?
I've used theplanet for years, but haven't used their support much. But after getting a new server, I discovered the configuration wasn't as promised (it was missing 5 IPs).
I left a ticket last Friday afternoon (12/4), but no response so I called support on the weekend. Although he promised they'd expedite it, the only result was a slightly sarcastic post to my ticket implying my expecting an acknowledgement within 24 hours was unreasonable.
I called on Monday, and the salesperson promised a manager would respond by Tue. Nothing by Wed, so I called again, and was promised that someone would contact me shortly but still nothing.
So now it's just a day short of a week after filing my ticket, and nothing but a runaround. Has their service gone downhill that much recently, or is it just me?

I have a problem with slow Apache 2.4.4. It's only related with https which is in general 5 time slower than the same site via http. I see this difference on the monitoring software which is measuring response time to http and https every 5 seconds. In some cases i got even timeouts in the browser on https while in the same time site is opening over http - slowly but opens always.
Apache runs on Win2k8 Enterprise, Version 2.4.4 x64 - VC10. Server is connected with quite poor internet connection as it's located in Africa. Despite of connection quality http is working properly all the time.

I am currently running Google Analytics/Urchin 5 (v5.7.02), on a server, the server has started to act up, (on its last legs etc) and now I am trying to transfer the Urchin Software to a new server, where it would work effectively.
However upon installing the urchin software on the new server and running it (localhost:9999), I am presented with An Action Items Page, and these following choices
Obtain Demo License
Buy License
Activate Pre-Purchased License
I choose ‘Activate Pre-Purchased License’ pop in the Serial number and complete the registration then…
---------------------------------------------------------
Urchin Licensing Center -- Error!
An error has occured during your transaction, please use the back button and correct the problem. The specific error message is:
• Unable to generate a license. Some possible reasons:
Your serial code is currently active <<< How do I disable it and use it on another server?
---------------------------------------------------------
So all I want to do is deactivate the serial and reactivate it on another server.
Does anyone have experience with this or a similar problem or have a solution to this problem. Any help be most appriciated.
Or even a Contact Number so that i can get some one over the phone!

I'm having a very odd problem with one of my Linux (CentOS) cpanel server, all the server's services (http, ssh, mail, dns, etc) stop responding but the server still responds to ping.
I can't find anything wrong at all on the log files either, and the technicians that manually restart the server have told me that there is no indication of a problem on the screen.
I suspected a hardware issue and had the data center techs run a hardware test on the server but everything cleared ok.
This issue started a couple of weeks ago, no major upgrade or install took place when it started happening. From what i can see the halts are completely random, some times it goes for days without it happening and some times it happens just hours after the reboots.
