Blocking requests port 80
hi
i have set up MX and A records for mail.domain.com but this can be reached typing it in a web browser and seeing the website when mail.domain is meant for mail, how do u block the request on port 80
You may need to explain your config in more detail.
Do you have your domain.com and www.domain.com web site running on the same machine?
Do you want webmail? (I ask because mail.domain.com can be set to go directly to your webmail)

Bridged Wireless Blocks TCP Port 9100?
On one of my networked computers, HP "Solutions Center" driver says HP 6310xi networked printer is connected, shows detail status & will print the HP diagnostic report direct to printer. Windows 7 shows printer on network map, & gives detailed status & setup info from printer internal data via IE through printer's IP address page (192.168.1.100); i.e. I can ping it. However, Win 7 printer control panel shows printer as "offline" on printers list & just ques up print requests. Troubleshooting gives error message "turn power on printer". Other networked PCs print OK. Bad computer is on a separate subnet of my home network, with a LinkSys wireless bridge WET610n connection, & printer is on another wireless LinkSys WET610n subnet. My network is totally LinkSys N, with a WRT 610n as main hub. All other network functions work for all other devices on the network, including DirecTV DVR receivers & Wii console!! I have moved the printer to the other subnet, & the problem is now mirrored by the computer on the remote subnet. It is not a firewall problem, but appears that the variables are the 2 wireless bridges that seem to conspire to block TCP port 9100 when in series. A single WET610n between the printer & a computer allows printing, proven by my roaming wireless laptop having access through the WET610n via the central wireless router. Very stange!! CTH
If I understand correctly, you have a Linksys WRT610N as your main wireless-router with two satellite Linksys WET610N configured as Ethernet bridges -- right?
You also have this setup:
Win7 PC -> WET610N -> WRT610N -> WET610N -> Officejet 6310
If I got this right, then the issue is probably the transit delay between the Win7 PC and the Officejet confusing HP's Solution Center.
I think you have two options:
1) Connect the Win7 PC directly to the WRT610N or connect the Officejet 6310 directly to the WRT610
2) Manually install the printer.
Let's try a manual installation:
1. Click >> Start >> Control panel >> Printers.
3. Click the Add a printer
3. Select Local printer
4. Select Create a new port and select Standard TCP/IP Port and click Next button.
5. Under Device type, select TCP/IP Device. Under Hostname or IP address, enter the printer's host name (found on the printer's network configuration report the generated above). Click Next.
If you get a message about Additional Port Information Required, then the printer was not found using the host name. You can go back and retry or using the printer's IP address instead of the host name.
6. Select Hewlett-Packard from the list of manufacturers and select and select your printer model. Click Next.
If your printer model was not listed, then select Have Disk, browse the HP CD that came with your printer and select the first file that starts with hp and ends with inf. Click Open then OK. Select your printer model. Click Next.
7. If you are asked, use the currently installed driver.
8. It will ask for the Printer name -- enter a new name or use the existing one. This will be the name of the printer that you select from other applications.
9. You may be asked to share the printer. Make a choice and click Next.
10. The Print Test Page box appears. Go ahead and print it.
11. Click Finish.
That should be it.

[Solved] SSH not working (ISP blocks my port 22)
OK full story:
I want to be able to connect to my home arch linux box from school. The setup there are winxp machines whit putty on my usb or the pc itself. I know that my school is not blocking any ports as my friend can connect to his linux box at home. (also ssh)
These are things i did and can think of i need to to do get ssh working:
Before everything else i started to configure my Linsys router.
My ISP gives me an Dynamic IP so i need to use the dyndns.org service. I made an account and configured my linsys router DDNS tab to work with the account. I got into the port forward tab an putted in ssh port forwarding (on port 22 TCP for my ip 192.168.1.102 => did ifconfig to be sure). Port forwarding for port 9091 is also on for my transmission webgui i'm saying this here because this works when i'm at school.
1. Installed openssh
# pacman -S openssh
All installed fine.

7. Im sure SSH is running i even did => /etc/rc.d/sshd restart
8. I have never installed any firewall on my arch box (that i know off). I can connect to it using my other linux laptop
ssh -p 22 192.168.1.102 => works
ssh -p 22 xxxxxx.dyndns.org => works (xxx replaced by my dyndns.org domain)
ssh -p 22 9x.xxx.xxx.xx5 => works (xxx is my normal WAN ip offcourse)
Keep in mind that transsmission port forwarding is working fine. I can connect from everywhere to my webgui wich is on port 9091. Anyone can help me get whats wrong?

I don't know if this is case-sensitive, but if it is: it should be "sshd".
If it doesn't work, doesnt hurt to try. -

Is there any way to block USB ports through SCCM console
How to Block the client machine USB ports using SCCM 2012 R2 console
we know that so many 3rd party tools are able to block the USB ports for client machines, how cant we add an additional option for SCCM 2012 for Block USB ports for client PC's, to make our network secure
thanks & Regards,
TejaThat's not possible by default, but you can create your own custom script and add it as a right-click action to a device.

[질문]WAS 이용시 gc cr multi block request 발생
OS 버젼 과 Word size : AIX 5.3 64BIT
DB버젼과 Word size : DB VERSION은 10.2.0.3 64BIT
RAC 환경이며 node1과 node2는 동일한 환경으로 구성되어 있습니다.
업무상 주로 이용하는 인스턴스는 node1 이구요.
파티션으로 구성되어 있는 테이블을 full scan하는 쿼리를 수행하는데
WAS에서 해당 쿼리를 날리면 gc cr multi block request 이벤트가 아주 오래 점유하고 있습니다.
동일 쿼리를 pl/sql 로 접속해서 2-tier로 쿼리하면 그런 이벤트 없이 바로 떨어지구요.
2-tier로 쿼리하면 15초,
WAS에서 쿼리하면 4~5분 정도가 걸리죠.
도대체 왜 그런지 알수가 없는데, 가이드가 될 만한 힌트라도 좋으니 의견 부탁드립니다.

Assigning static request ports
Hi,
Due to our firewall deployment, we have to assign static request ports for serveral servers in the CMC in BI 4.0. This can be done manually, but we would like to script; we plan to use silent install so one wrapper script to do the install and then assign the ports would be great!
Note this is BI 4.0 on windows... so my feeling is this is not possible (windows is not great for scripting), but would be really happy to be proven wrong!
Thanks,
TadhgFirst and foremost, this definitely belongs in Idea Place. Whether it be setting command line arguments via the BIP SDK, or setting default firewall configuration for new services, this behavior would be useful in a number of scenarios, including onboarding new tenants in a multi-tenant environment. In the XIR2 days you could have accomplished this through a simple .reg file that modified the service parameters in the Windows registry. Since the SIA now controls the relevant services they read their command lines from the system database like Graham mentions.
I do have a couple of thoughts on this, though I admit I haven't tested any of this so can't guarantee it would work.
Set your requestport properties in a test environment, and use the BIAR command line option (see section 15.5 on Page 520 of the FP03 admin guide) to backup the relevant server instances. You could use a query like:
select si_id, si_kind, si_current_command_line from ci_systemobjects where si_kind = 'server'
Since the default servers should always have the same SI_ID you could script the LCMCLI to update your server objects with the appropriate command line immediately following the installation.
Again not entirely sure this would work but perhaps something worth trying... -
I want to block incoming ports WRT54G!
Hi!, I want to block some ports for aplications from incoming data , im enabling the router "Wrt54g" firewall and disable Upnp. Ok im going to grc.com "Shieldsup test" are stealch! All apps ( nod32, firefox, messenger msn) can open ports! Why the applications turn on the ports? , Do they appear "stealch" but not closed? From outgoing ports im using comodo firewall on vista. Thanks! and sorry my english!
on the router's web ui , click on the "access restrictions" tab and block the ports you want ...

Hi ,
I am sufferiung from a 40 hour long running job which normally completes in few hrs, that jus creates a table (actually create table as select,joining many tables using parallel query withe 16 sessions).
There is only 2 session that are active at this time, one of them is the parent waiting on PX:DEQ EXECUTE REPLY.
The other sesion is running from 24 hrs, it is actually not waiitng upon any event for a signifcant time.Most of the time it faces GC CR MULTI BLOCK REQUESTS wait event. Is this due to interconnect latency?.I guessed it because the protocol used by the interconnect is UDP which doesnot wait for an acknowledgement. Can you please suggest me how to check for the latency on the interconnect?? Is my doubt on the interconnect is reasonable???????????
I checked the trace files,awr reports,ash reports and every thing but nothing seems to be working fine. All I see is that single sesion using up 98% of the CPU and the TOP wait event in the awr,ash reports being the CPU Time.Pleas help me.Thanks.You are difficult to help as you don't post
- a four digit database version
- information on your OS
- information, including configuration info, of your interconnect
RAC is a chatty protocol, and sends large packages, of even 64k and higher. This means if you don't use an 1 Gb network card, and don't have 'jumbo frames' enabled, performance will suffer.
As a result, at least in 9i, you will see this very wait event show up all the time, at least on AIX.

Strange 'gc cr multi block request' during dictionary queries
Hi,
here goes the case :
I've got 4 node 10.2.0.3 RAC , DDL intensive (CTAS, DROP/TRUNCATE) database
It's like 20TB of data, milions of partitions and objects .
When I'm doing queries agains dictionary tables like select * from
dba_segments where owner = 'A' and segment_name = 'B'
I'm observing 'gc cr multi block request' , as far as I know its kind of
scattered reads but using interconnect to gather data .
Whats bothering me is profile of that 'gc cr multi block requests' , here
goes some lines from 10046 trace:

and that pattern repeats with different block#
Question is why Oracle is requesting the same block , over and over (16
times) , I thinks 16 comes from MBRC which is 16 and I've got 16kb blocksize
Looks like a bug :) isnt it ?
Generally all queries agains dictionary tables are slow (minutes) , I'm not
observing any lost block issues so its probably bad plans issue .
Any comments ?

Blocking outgoing ports on airport extreme
I have a current generation (mid-2014) Airport Extreme as the wireless router for a network at a small guest house/holiday home. Our broadband internet service is provided by satellite and we have therefore a usage limit as well as a restrictive FUP/Traffic management policy.
What I'd like to be able to do is block certain ports/ip addresses from outgoing traffic. That is, I want people not to be able to use the network for really intensive stuff, things like streaming video (e.g. hulu plus, BBC iPlayer, netflix, that kind of thing), background p2p, and torrents, as it'll eat up all our broadband usage and bring our overall speed to a crawl. I see that there Airport Extreme doesn't have that kind of ability built-in to the software like some other routers do, but am I right in surmising that there might be an option of configuring it so that outgoing traffic to certain IPs be port-forwarded to a non-existent device on the network (for example)?
If so, can someone just help me with that process. Or if there's another process that I can use to block certain kinds of traffic.
Many thanks!It is simply not possible.. the AE is the wrong device in this setup.
I would strongly recommend a cheap router with 3rd party firmware.. eg... TP-Link WDR3600 with gargoyle firmware.. just google for the info as I have had it deleted by mods here in the past.
It will allow you to set daily quotas on usage. You can let people do whatever they like.. but they can only use a set amount per day or week or whatever time period you set. This firmware is unique in providing this ability in a domestic router.. for free. -
We are using BM 3.9 (no SP1 yet).
I'm trying to block a Windows Media Player stream. If I put the URL that WMP uses into a deny rule, the BM log shows the html page is forbidden, yet the media still comes through.
So I tried blocking all ports on the host. I put in a Deny rule that blocks All TCP&UDP on both the IP address and the host name. Yet, when I type the URL into WMP, I still get the stream. How do I block this with BM?
Incidentally, after All ports didn't work, I tried specifying ports 0-65535. But I got an error that that was an invalid range. It did let me use 1-65535, though.David,

I have a customer that has an Airport setup for their clients (it is a restaurant) and they have been hit with some DMCA notices, as someone is downloading torrents while on their network.
How do I block all ports but 80 on the Airport?Look for a firewall. I am sure there are some. Not sure of the requirements though.
It looks like whispermonitor may be a good option. -

Global cache average current block request
Hi all experts,
I am getting this error frequently through 12C EM. Please tell me how I can suppress this alert so that I don't get it in future.

Type=Database Instance
Host=<servername>.<domainname>
Metric=Global Cache Average Current Block Request Time (centi-seconds)
Timestamp xxxxxxxxxxxxxxxxxxxxxxxx
Severity=Critical
Message=Metrics "Global Cache Average Current Get Time 62" is at 1.46154
Rule Name=XXProd
Rule Owner=SYSthis metric needs to be disabled in EM at the target level for each instance. you can disable "Global Cache Statistics" metrics in two different ways:
Navigate to the instance, then click the Oracle Database drop-down -> Monitoring -> All Metrics -> (expand) Global Cache Statistics
-> Global Cache Average CR Block Request Time (centi-seconds)
-> Global Cache Average Current Block Request Time (centi-seconds)
-> Global Cache Blocks Corrupt
-> Global Cache Blocks Lost
a. At the top level (Global Cache Statistics), click the [Modify] button , then the (*) Disable radio button to disable the entire group
b. If only disabling the individual metric (Global Cache Average CR Block Request Time (centi-seconds)), click on Modify Thresholds button to delete the values. Note that empty Thresholds will disable alerts for that metric.
Same can be done via navigation to the Cluster database instance -> Oracle Database drop-down -> Monitoring -> Metric and Collection Settings -> Global Cache Statistics
