Linksys WRT54GL won't get dhcp address from isp

I'm using Linux.
I just bought this router because it had good reviews on Newegg but for the past 4 hours I have gotten nowhere with it.
When I connect the router to the net and click the refresh button on the browser interface, the router doesn't go out and get a dhcp address. I see the initial click of the mouse that hits the modem but no information comes back. No addresses are updated.
I have tried cloning the mac address but that does no good either.
Any hints appreciated.
Thanks

Try resetting the router for 30 secs in such a way that power light is blinking on the router.Also, try doing the complete network power cycle i.e., unplug the power cables from the modem & from the router.Then, plug in the power cable to the modem first once all the lights are solid on the modem you could plug in the power cable to the router & then try configuring the router & it will definately work!!!

VWLC clients getting DHCP address from management VLAN

Hi,
We have a strange scenario whereby some wireless employees are obtaining addresses from the management VLAN.
Some details:
DHCP managed by MS DHCP 2008 R2 (in remote data centre)
Cisco vWLC AIR-CTVM-K9 running v7.6.110.0
AP's are a mix of 2602 and 3702 (46 and 2 of each respectively)
SSID's are employee, guest, and production devices (all mapped to their own interface with relevant VLAN tag as per normal)
AP's all in FlexConnect mode as per vWLC caveats
Some employees are receiving addresses in the wireless management VLAN. This network only has six DHCP addresses available as it is solely for AP's, WLC and HSRP gateway. Obviously this gets exhausted very quickly leaving us with a scenario where clients are not obtaining DHCP addresses.
I understand that with FlexConnect mode, it will assign IP's from the native VLAN. What I don't understand is why most clients receive addresses in the correct VLAN, but a handful do not, and then cannot get an address from DHCP. Obviously the ideal scenario would be to put the AP's into local mode but unless this has changed in a SW release then I don't believe it's possible...
My question is: How do I get ALL the employees to obtain addresses from their interface and not the management VLAN?
Thanks in advance.

Hi,
I think we need a closer look to your configurarion to eliminate some possibilities:
- What is the WLAN security you choose?
- What is the interface that is configured under the WLAN?
- Does your WLAN have local switching enabled?
- If your security is using RADIUS server, do you have AAA override enabled under the WLAN config?
- If your security is using RADIUS server, do you send any attributes to the users?
- You have eliminate that clients that got management vlan IPs are always on same AP or they can be on any AP.

Mac mini server refuses to get DHCP address from router

Everything was going along fine. But after a power outage the server goes to a 169. address when the router puts out 198. addresses. If I put a static 198. address in it sees the network but won't connect to the internet. I've flashed the router (everything else sees the router fine, 3 computers and a time capsule). I've had the hardware checked at the Apple store - it picked up an address right away. After narrowing everything down the problem has to be in the operating system. I even did a full time machine restore to the day before the storm. No luck. Anyone heard of this problem.

Mauricette has a point.
A server function is not designed to accept a floating or dynamic IP address. If that is the case, how do you create firewall rules that prevent those unnnecessary ports being left opened from being attacked by rogue machines in Romania and China on a hourly basis when you announce to the world that your server is available if the server IP address keep changing due to the DHCP lease change? Yes, they do have bots that do this VERY EFFICIENTLY!
By changing the very nature of your firewall rules by working with DHCP, you are opening ports you do not know to accommodate DHCP dynamic addressing, which was the reason why your Mac Mini Server stopped working in the first place. It's ok for a client, since a client isn't serving any files to any one right.
By using client based firewall rules, you are exposing your server to attacks and when they get through your Mini server, which they can if they are persistent, they get into your home network and then whatever file server services you have opened and unprotected at the time WILL BE copied by these people easily.
I have a client once who did just that. She was attacked, the hacker went through her network like a rampaging bull. They were from China. My Synology RAID server gets this attack all the time, but I have a well establish IDS system and the Synology RAID has logs that tracks attacks.
For a server setup. Use static IP and then build a strong firewall around it and protect it and never compromise.
Recently, I just noticed someone somehow hacked and broke my WPA-PSK AES passkey for one of my Wireless N network router. It was not set up with a strong password though, but thankgod I had a firewall around that so my internal networks were safe. So this teaches you that if someone wants in bad, they will get in.
Hope this helps.

SPA525G Won't get DHCP Address

So I have a couple of brand new SPA525Gs right out of the box and we are having trouble with them on the network.
I've setup a sniffer capture to see what's happening and it looks like the phone sends out a dhcp request but never accepts the offer from the switch.
I then setup a static IP address on the same subnet and it will not respond to the ARP requests either.
If I connect it back to back with my laptop, however I can ping it and get to the web interface fine.
Other older 504 and 525 phones are all working fine on this same subnet and switch port.
The phones came with version 7.5.2a and we upgraded them to 7.5.5 still does the same thing.
Has anyone else seen this? Small business support didn't offer up much help.

Lacie 2Big Network Drive won't Accept a DHCP address from Time Capsule

Good evening all.
I have 2 of these Lacie 2Big network drives. One accepts a DHCP address from my Time capsule and the other does not, giving itself a self assigned IP address instead. It does accept a manually assigned address though. The settings on both the Lacie drives are identical as far as I can tell and they both run the latest 2.0.6 software. I tried hard reset on the Time capsule, and swapping the ethernet cables over on the two Lacie drives but to no avail. The log on the drive that won't accept a DHCP address says it is timing out after 45 seconds and setting a self assigned address. The drive that won't accept DHCP is an older drive with software updated to 2.0.6, but it had the problem with the older software as well. Does anyone have a similar experience and / or solution ?
regards
Shaun

Also tried resetting PRAM, no luck.
What does work is if I use Manual DHCP mode and specify the router's address (192.168.0.1). Then everything works but not on Automatic, which worked for a long time.

Cannot get a DHCP address from my ISP

I just got a WRT54G router, I managed to configured it all. I can ping any computers on the network. What I cannot do is get my DHCP address from my isp, meaning that I can't connect to internet.
I am 100% sure that my ISP address was given by a DHCP server since that's how it was configured on my old router before it got smashed into pieces.
I have the latest firmware upgrade for the router (version 6) and it is correctly plugged in my modem.
What is strange is that couple of hours ago, I managed to get an address for about 15 minutes, then it dropped and I have not been able to pick a new one anymore, no matter what I do.
Anyone can help me?

Alright, but how do I do that?
Disconnect the power cord.
Or if its a telephony modem, hold the reset button until it reboots.

Windows will not get a DHCP address from my OS X Server

Is there a trick I need to do to get my windows machines to get and address from my OS X Server?

i have had the same issue. Windows clients (XP, 2003, 7) just could not receive an address from the dhcp server.
I think i got it solved by removing an invalid line in my dhcp server config file.
This is what i did:
stop dhcp server
open /etc/bootpd.plist (you need admin rights to edit)
remove the following two lines:
<key>dhcp_domain_name</key>
<string></string>
save file
start dhcp server again
alternatively, you can fill the dhcp_domain_name with a valid domain name suffix. Both options seem to have worked just fine for me.
<key>dhcp_domain_name</key>
<string>whatever.mydomain.com</string>
Tips:
I am using Sublime Text for such tasks. It asks for administrator password when trying to save the file, much more convinient than trying to use TextEdit
To get to the /etc directory from your favorite text editor easily: Go to the standard open file dialog. Press Cmd+Shift+G. Type /etc and press enter
also see the official documentation:
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man8/bootpd.8.html
dhcp_domain_name
The default DNS domain name (option code 15). If this property is not
present, the server will supply its own default domain name (if available).

1811W router unable to get DHCP IP from Speedstream 4100

I have a Yahoo-ATT DSL installation with 1 dynamic IP address. It uses an ISP supplied speedstream 4100 DSL modem. The 4100 appears to take care of all the PPOE duties and DHCP connections from PCs or low-end routers (I'm temporarily using a NetGear unit) work fine.
BUT, when I swap the Netgear out for my new 1811W, the cisco unit is unable to obtain a DHCP address from the modem. I can see the request on the modem lights when I do a "no shutdown fastethernet0"...but I never get an IP address.
The speedstream appears to support 100Mbps and I have tried 100, 10 and Auto on the 1811W. I can look at the log on the modem and it does not show any activity by the modem's dhcp service. However, when I swap back to the netgear unit, I can see appropriate entries in the modem log.
The 1811 is new and I strongly suspect its working ...I tested it on a different DSL line that had static IP. I see a number of similar issues in this forum; but have not seen any resolution that seems to fit my situation.
Any help/suggestions would be appreciated...my next step will be log the DHCP packets with a sniffer. I think I know what I"ll see...1811W DHCP broadcast...no response. But, that won't help me resolve the issue.
Thanks,
Chuck McP

Hi, this would a config example once you configure the dsl modem for bridging:
http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a0080126dc0.shtml
look at the 2600 part. you can omit these commands that are for older versions:
vpdn enable
no vpdn logging
vpdn-group 1
request-dialin
protocol pppoe
Hope this helps, please rate post if it does!

2611XM refuses to grab a DHCP address from an upper router.

HI, first time here. Im a homeschooled student and trying to work on getting a CCNA. I ran into an issue which puts me in a stopping point. I have a Cisco 2611XM router in which im trying to pass internet traffic to a few select computers. The problem is the WAN (fa0/1) will not get an address from the d-link router which is handing out dhcp addresses to all my computers in the main network. Ive watched lots of youtube videos but only to validate Ive used the same methods they did. SO here is a quick run down of the topology.
cable modem>dlink router>cisco2611XM>dumbSwitch>Computer#3
> >LinksysSLMG224G 24 port switch>computers 1,2
As you can see my network splits off from the dlink into what needs to be 2 networks.
So why cant I get the WAN interface of the 2611XM to grab a dhcp address?

No Hyperv Virtuals get DHCP address - but Physical Host Can

HyperV Server 2012 Core on a dedicated machine on local domain.
Machine connected directly into local network that has a DC running DHCP.
None of the VM's can get a DHCP Address from the server. Even if i set static addresses still they cannot route anywhere, cannot even ping the HyperV server they are sat on but other local machines can!!!!
The physical host cant ping the
The physical HyperV server has no problem getting a DHCP address or any routing issues, nor do any of the other clients on the local network, including another HyperV server running server VM's
What ive tried so far
Deleted Virtual Switch and removed the NIC from the virtual hosts in HyperV Manager- then re-adding new one.
Put in a different network card
Removed Physical host from Domain, renamed machine to different name and re-joined
Used different IP addresses for the Physical host
Reloaded the HyperV server from scratch and created new VM.
Ive had HyperV previously running on this machine without problem, so now i cant see why i cant get it running again.
Anybody have any suggestions on what i can try next, im all out of ideas.

Hi Fulgent,
I am assuming that , the hyper-v server have two NICs , one for host and the other one was configured as an external switch for VMs .
If the VMs can not access the dhcp and local network , please try to delete the external switch then uninstall the Physical NIC in device manager and click " scan for hardware changes " to reload it.
Try to create external virtual switch for VMs again .
Any further information please feel free to let us know .

AEX fails to get DHCP address, but works on DLink

Sorry for the long post -- I'm hoping the details will help you diagnose the problem faster in the long run.
My DLink router gets a DHCP IP address from the (Comcast) cable modem, but when I switch to the AirPort Extreme (5th gen, refurbished), it doesn't. It shows an autoconfiguration IP address of the 169.254 variety, suggesting that DHCP isn't working for the AEX. (Just fyi, my girlfriend's macbook can connect to the AEX and get 10.0.1.x IP addresses; I can ping the AEX over wifi.)
Airport Utiltiy shows a red number 2 with a single error indicating Internet failure to get IP address or something. The suggested solution is power-cycling the modem; failing that, contact the ISP. Contacting Comcast was amusing but useless...they gave me instructions for setting up AEX with a DSL modem -- twice -- without understanding my objection!
The AEX is configured for DHCP (not Static or PPPoE), and uses all stock settings (I did both a soft reset and used the Airport Utility to restore default settings...not sure if those two are the same).
I've tried power-cycling the router and cable modem numerous times, including leaving them off for 15+ minutes and leaving the AEX connected for 6+ hours. I tried using the DLink to release the DHCP reservation and then quickly switching the cable over to the AEX.
I read somewhere that resetting the "CMTS (cable modem termination system)" might help. I mentioned it to the Comcast tech support, but they didn't respond.
At this point, I'm not sure what else to try. It could be the refurbished unit is broken, but 95% of the time these sorts of things are configuration issues. (I know a fair amount about networking, but I'm new to Apple products so I could be doing something stupid.) I may try connecting the AEX to the LAN side of the DLink to see if it can get a DHCP address from that...but I'm clearly grasping at straws.
<whimpers>...Help?

Update: The AEX does get a DHCP address when connected to the LAN side of the DLink gateway. (But the AEX doesn't get one when connected directly to the cable modem. Yet the DLink gets a DHCP address when connected to the cable modem.) So...??!?!!!

How can I get the address from a map struct?

Hello,
Who knows how to get the address from a map struct, and what's the meaning of the eighth argument (addr) of ufs_getpage() ?
I developed a modular to encrypt certain files. The approach is: I�fll change the vnode's v_op pointer when opening a file which should be decoded. I make the vnode->v_op point to my own ops struct. I made a new ufs_getpage function like below:
static int newufs_getpage(struct vnode* vp, offset_t off, size_t len,
uint_t* protp, page_t* plarr[], size_t plsz,
struct seg* seg, caddr_t addr, enum seg_rw rw,
struct cred* cr)
call old ufs_getpage(vp, off, len, protp, plarr, plsz, seg, addr, rw, cr);
decode the page.
After reading some source code about kernel, I know the plarr is the page which is read from the disk. But I don't know how to get the address of the page. I tried like below, but failed.
caddr_t baseaddr;
page_t *pp;
pp = plarr[0];
�c�c
baseaddr = hat_kpm_page2va(pp, 0);
�c�c
I logged the baseaddr:
cmn_err(CE_NOTE, �gbaseaddr %s�h, baseaddr);
or
char _buff[8];
int _len;
copyinstr(baseaddr, buff, 8, &len);
cmn_err(CE_NOTE, �gbaseaddr %s�h, _buff);
But I found the baseaddr is not what I want. Is there something wrong with my approach? What's the meaning of the eighth argument (addr) of ufs_getpage()
By the way, is there any documents concerning to the functions such as segvn_fault�Appmapin/ppmapout except the source code?

Hiya,
I think the address is the faulting address in segmap.
But why not have a look at the file event management framework in NFSv4:
http://cvs.opensolaris.org/source/xref/on/usr/src/uts/common/fs/fem.c
To support NFSv4 delegation, FEM provides hooks to intercept filesystem operations.
Maybe you could use that to implement what you want? Probably safer than doing what you are doing now. Go see fem_install().
Cheers,
R.

Need powershell commands to get email addresses from public folder created in EAC to CSV

Need powershell commands to get email addresses from public folder created in EAC to CSV
1. Created Public folders via EAC - not mail enabled - just to hold contacts.
2. Assigned owners and showed to add new contacts - then add to favorites and finally to display as address book.
Now I need a powershell command to get those email contacts in those public folders.
I need to view them because when we send emails to those groups (via select all) in the public folders, it is creating an NDR for 3 users saying - "..blah blah -OFFICE FAX or HOME FAX) - yet they are getting the emails.
I suspect that their contact details are corrupt somehow and want to see what contacts are actually listed in the public folders. I already checked to see if the source of the contacts was the public folder or "my contacts" and they are not.'
I have tried multiple get recipient commands and get public folder commands with no results in the CSV

The only way to get that data is either via the Outlook com object or using EWS. None of the commands in the Exchange shell look inside of a folder, the most you can get with those is email addresses for mail-enabled Public folders. Here is a link that can
get you started with how to connect to public folders via EWS, then its just enumerating the folders and looping through the items in the folders for the details of the items.
