Main Server cannot ping the 2nd server in another location but the 2nd server can ping the main server

I have 3 servers : Main server, and 2 file servers in another country.
My main server can only ping the 2nd file server.
But both of our 2 file servers from another country can ping the main server.
In short, I cannot remote to the first file server.
The settings on both file servers are the same. And I don't have issues in accessing the 2nd file server using the Main server.
Can somebody have the patience to help me figure out the issue?

Being able to ping the server does not mean that you remotely access it.
If you are trying to RDP a server then you need to check that RDP is enabled on the server and that traffic to port 3389 is not blocked or filtered. You can use PortQryUI for checking.
For testing, you can temporary disable security software running on the servers and try again. Also, check the filtering done on network equipment in between your servers.

My 2nd gen works fine with WPA2 and AES encryption.
You may need to go back and start over. Reset the router back to factory defaults, log on as the admin, set up security, DHCP, and make sure the IP address pool has enough IP addresses to lease to ALL of the computers/devices that will connect to that the router.

Cannot start the presentation server

OBIEE gurus,
I cannot start the presentation server via EM or via the command line ./opmnctl startproc ias-component=coreapplication_obips1.
I get the error in the comman line:

I have tried refreshing the user GUIDS, loading another rpd file in through EM that I know works fine in another environment, cleaning the permissions in the web catalog but all so dar have not resulted in me being able to start the presentation server.
I would welcome any feedback on this as it is driving me crazy!
Thanks in anticipation.

Hi ,
I tried it but no use. That thread had some errors displayed in it. But i get just a warning.

1602i standalone AP cannot ping RADIUS server

I have a new 1602i standalone AP trying to use RADIUS authentication. For some reason the 1602 cannot ping the RADIUS server, but will get a response from other devices. Both are on the same subnet, the new one at .213 and the RADIUS at .209.
AP6#ping xxx.xx.120.209
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to xxx.xx..120.209, timeout is 2 seconds:
Success rate is 0 percent (0/5)
AP6#ping xxx.xx.120.217
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to xxx.xx..120.217, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms
The RADUIS server is able to ping the new AP successfully.
AP1#ping xxx.xx.120.213
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to xxx.xx.120.213, timeout is 2 seconds:

Any thoughts to why that AP is unable to ping that one particular client? Other APs are successfully contacting it for RADIUS authentication.

Cisco C6500 CSM - Real server cannot ping its VIP.

I've been running into an issue with Cisco CSM for a number of years, but always found a way around it. Im attempting to get to the bottom of this to find out once and for all, if this is infact a limitation of the device, or a config issue/work around is possible.
Here is my situation. My CSM's are configured in bridging mode. Traffic works great, traffic bridges across vlans correctly. Everything works and have many instances of smilar configurations running in production. Every once and a while, a client requests that a "real" server (ie LWCMW-021)
cannot ping its VIP address (10.95.88.68). I am assuming this is related to the NAT Server, but not 100% sure. Clients have requested this functionality for some type of application based purpose, but Im unaware if CSM in bridging mode can provide this or not.
Any suggestions?

Sorry for giving false hope. It is only possible in ACE module. In case of CSM I believe we can only use workaround.
In case of ACE we can bind the Virtual IP to mutliple vlan. In that case we see a ARP entry like this.
10.10.10.111    e0.5f.b9.a1.72.2b vlan345   VSERVER    LOCAL     _         up
10.10.10.111    e0.5f.b9.a1.72.2b vlan346   VSERVER    LOCAL     _         up
As Virtual IP is not bound to a particular vlan in case of CSM it does not work here, but I can say for sure it is expected behavior.
The logic would be that the server tries to resolve the ARP for Virtual IP and it does not get a response.
In my case virtual ip is 10.10.10.111 before applying policy on ACE you can see that it is exhibiting the same behaviour.

Cannot ping RRAS Client from RRAS server.

I have recently created an RRAS pptp connection for an outside network. The RRAS client connects fine and can ping the RRAS server and every device on the RRAS servers local network. The RRAS server cannot ping the remote pptp client nor can any device on
the RRAS servers local network. RRAS is configured to be within the same subnet as the RRAS servers local network. On connection it pulls from a static IP pool.
Any help is truly appreciated

The server is behind a nat device and for testing purposes i have disabled the firewall on both devices. Also I am having an issue where the pptp connection just stops accepting and sending data to the rras server but if you look at the active connections
the client never disconnects. I have attached ipconfig information

Cannot ping from zone or ping zone from another server

Hi all,
I've just setup a zone, configured the OS on it and booted it.
1) From the global zone I can ping the zone
2) From another server(s) I cannot ping the zone although I can ping the global zone
3) From the zone I cannot even ping the global zone let alone anything else
Any ideas whats gone wrong. the zone xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE zone PUBLIC "-//Sun Microsystems Inc//DTD Zones//EN" "file:///usr/share/lib/xml/dtd/zonecfg.dtd.1">

<zone name="ivcp0.lon.oss.colt.net" zonepath="/zones/ivcp0.lon.oss.colt.net" autoboot="true">
<inherited-pkg-dir directory="/lib"/>
<inherited-pkg-dir directory="/platform"/>
<inherited-pkg-dir directory="/sbin"/>
<inherited-pkg-dir directory="/usr"/>
<inherited-pkg-dir directory="/opt/sfw"/>
<filesystem special="/home" directory="/home" type="lofs"/>
<network address="212.74.77.211/25" physical="bge1"/>
</zone>
zoneadm list -vc
ID NAME STATUS PATH
0 global running /
2 ptl1.lon.oss.colt.net running /zones/ptl1.lon.oss.colt.net
3 ptl1.dev.lon.oss.colt.net running /zones/ptl1.dev.lon.oss.colt.net
7 ivcp0.lon.oss.colt.net running /zones/ivcp0.lon.oss.colt.net

Might help to send along the "ifconfig -a" and "netstat -rnv" output from both the global zone and the local zones that are having problems.
Traceroute might also help you isolate the problem

Cannot ping REAL server IP addresses from CSM 6500

I have a dual 6500/CSM routed topology in which the traffic from clients to the server VIP works fine. However, in preparation for some upcoming work, I find that I cannot ping the REAL server IP addresses. This would seem to be an important troubleshooting step. Any ideas why this wouldn't work?

Gilles, followup question. If I understand this, what you outlined above will allow traffic external coming into the 6500/CSM to be forwarded thru to the REAL server IPs. If it wasn't clear, I was trying to ping from the native-mode 6500 that contains the CSM. I've tried regular and extended pings using the CSM-configured server VLAN's IP and alias IP, but get no response back from any of the REAL server IP addresses.
Is what you've indicated required to ping even if I'm on the 6500 which contains the CSM?

IPV6 clients cannot ping each other while getting IP from DHCP server running in windows 2008

I have two windows 7 clients and a windows 2008 server connected to a switch with static IP 172:16:5::1/64.
DHCP server is configured with static IP 172:16:5::20/64
when i statically assign IP to windows 7 clients like 172:16:5::21 & ::22, they can ping each other. if they get ip from DHCP server, they cannot ping each other.
if i configure the gateway (172:16:5::1) in the clients manually, they can ping each other.
is there any way we can make dhcp server to give gateway to the clients along with IP?

From what I have gathered:
IPv6 won't route because the DHCP server is setup in 'stateless' mode and the switches do not support IPv6. (
"But if your routers are not IPv6 supported (yet), you can
reconfigure DHCPv6 to Disable Stateless mode, and that'll issue IPv6 addresses that
will eliminate the Ping problem." -
http://www.networkworld.com/article/2228461/microsoft-subnet/setting-up-dhcpv6-to-dynamically-issue-ipv6-addresses-in-a-network.html)
So you must change to 'disable stateless' mode. Which the only way I can THINK to do this is to uninstall DHCP and reinstall DHCP and select 'disable stateless' during the installation (which I haven't confirmed). (In
case, “Disable DHCPv6 stateless mode for this server” option was selected duringrole installation" -
http://blogs.technet.com/b/teamdhcp/archive/2009/03/03/dhcpv6-understanding-of-address-configuration-in-automatic-mode-and-installation-of-dhcpv6-server.aspx)
zz.. but my understanding of DHCP is fragmented, please take what I find with a grain of salt. I am off to reinstall DHCP :] .. fun.

Can not receive Mac mail -error Outlook cannot find the server. Verify the server information is entered correctly in the Account Settings, and that your DNS settings in the Network pane of System Preferences are correct. Account name: "MacMail"

Can not receive Mac mail -error Outlook cannot find the server. Verify the server information is entered correctly in the Account Settings, and that your DNS settings in the Network pane of System Preferences are correct. Account name: "MacMail"
What are the correct mail account settings and more importantly the correct DNS settings
Thank you for any help you may be able to provide

Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
          •          Server name: imap.mail.me.com
          •          SSL Required: Yes
          •          Port: 993
          •          Username: [email protected] (use your @me.com address from your iCloud account)
          •          Password: Your iCloud password
SMTP (outgoing mail server) information:
          •          Server name: smtp.mail.me.com
          •          SSL Required: Yes
          •          Port: 587
          •          SMTP Authentication Required: Yes
          •          Username: [email protected] (use your @me.com address from your iCloud account)
          •          Password: Your iCloud password
Also, you must upgrade your password to meet the new criteria: 8 characters, including upper and lower case and numbers. If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message. Go to   http://appleid.apple.com         then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.

Safari will not open on my iPad Air...."Safari cannot open the page because it could not connect to the server." There were recent updates on my iPad Air. How can I fix this problem?

How can I correct the issue of Safari not connecting on my iPad Air? It was working great 2 days ago.....now on September 20 it is not working! I have an internet connection but Safari will not open. "Safari cannot open the page because it could not connect to the server."

Hello Beckieor,

Safari cannot open the page because the server cannot be found

Trying to open Outlook Webmail App from Ipad 2 and am receiving the Error Message "Safari cannot open the page because the server cannot be found.
I have tried resetting my ipad 2 to no avail. Internet connection is working and am able to get into other apps/sites. Read older posting that this could be a DNS issues???
Help?

The only other thing I can think of is to try a device reset (be sure and also close off all running apps beforehand):
Device Reset (won't affect settings/data/music/apps/etc)
1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

Safari and firefox 'cannot find the server' for every other page that i navigate to, unless I turn Wifi off and on. How do I fix this?

Safari and firefox 'cannot find the server' for every other page that i navigate to, unless I turn Wifi off and on. Once i reconnect to the network, the page loads, but after loading a few more pages, the same thing happens all over again.
This happens each and every time, on different Wifi networks, in different locations. On the other hand, I don't ever encounter this problem when I tether my laptop to my mobile phone's 3g/2g network using Personal Hotspot. How do I fix this?

Try this DNS server ...
Open System Preferences > Network > Advanced > DNS
Click + and type:
208.67.222.222
Click + again and do the same.
208.67.220.220
Click OK.
Quit and relaunch both your browsers to test.
If that doesn't help, try here > iOS: Troubleshooting Wi-Fi networks and connections

I have an iMac, and have a Verizon DSL account. Recently, my Mac Mail keeps requesting the passwords on my account every few minutes, and will not allow me to send messages using Mac Mail. I cannot edit the outgoing server; how can I send emails?

I have an iMac, and have a Verizon DSL account (3 email addresses). Recently, my Mac Mail keeps requesting the passwords on my accounts every few minutes, and will not allow me to send messages using Mac Mail (the message says that the outgoing server was rejected. I cannot edit the outgoing server, and the keychain will not save my passwords (the ports are valid). How can I change the outgoing server to send emails, and how can I avoid having Mail request my passwords every 2 minutes? Verizon, as usual, will not provide support to iMacs.

Is there an email saved in your drafts or outbox folder? I suspect that Mail is continually trying to send it, and each time Google is rejecting the email message.
You can open the message and then delete it from your Outbox folder. Then try removing all @gmail email addresses from it and seeing whether you can send to the other folks. I suspect that will work.
With email, if an SMTP server *can* verify email addresses, sometimes it will and it will refuse to send messages. If a message has to be relayed across servers, no verification is done, and you'll get a bounce if an email address is bad.
