Unable to telnet or user disconnected

Hi,
It seems that every time a client/server application runs extensively on the Sun Solaris 7 server, users who are already connected to the server got disconnected or we're unable to telnet or ping the server (connection got timeout). I increased the pty's to 128 but still no luck. Traffic on the switch seems ok.
Any idea someone.?
Pls help
Rales

Are you able to console to the access point? Do you have an ACL preventing telnet or HTTP access to the AP? Is there a chance that HTTP and telnet are disabled on the AP?

Unable to telnet and tftp to controller

hello experts!!!
5508 controller is at the headquarters which can be normally pinged, telnetted, http'd and tftp'ed....
at the remote site, controller can be pinged and http'ed but cannot be telnetted and tftp'ed.
there is a complete tracert from the remote site pc all the way to the controller.
from a switch at a remote site, the controller can be telnetted.
but from a pc on the remote site (which belongs to a remote site vlan), it is unable to telnet and tftp the controller.
all active components can be telnetted from the remote site, such as the core switches and routers at the headquearters, except the controller.
upgraded the controller code to 7.2.xxx in headquarters but still unable to telnet and tftp the controller from remote site.
is there any more settings on the controller for telnet and tftp?
what could be the problem why the controller is not available for telnet and tftp from the remote site?
thank you, experts, in advance for your replies!!!

Unable to telnet SLM224G2

hi.
i am able to ping my SLM224G2 switch but unable to telnet the switch.
pls. help me out.
Jitendra

I am not sure if the SLM224G2 if you can telnet the unit but if it does have that option usually you might have some enabled firewalls in the PC that is why you are unable telnet the unit. I tried to further look at either the user guide or datasheet for the SLM224G (anyway the SLM224G2 should belong to that family) and it doesn’t say that it has a telnet capability. I am honestly not familiar with this switch but I know the SRW series has telnet capabilities. I suggest try contacting CISCO tech support to report about this problem and seek their opinion about it.

Hi Marko,
That means I could not to configure redundant-interface as I have redundant-vip configured already?
Actually the topology is:
VLAN550 is connecting to server farm
VLAN145 is where user sitting
my current config :
circuit VLAN145
ip address 172.19.145.182 255.255.255.0
    ip virtual-router 1 priority 101
    ip redundant-vip 1 172.19.145.184
    ip redundant-interface 1 172.19.145.183
    ip critical-service 1 PING_DEFAULT_GATEWAY
circuit VLAN550
ip address 192.168.50.18 255.255.255.0
    ip virtual-router 2 priority 101
    ip redundant-vip 2 192.168.50.20
    ip redundant-interface 2 192.168.50.19
    ip critical-service 2 PING_DEFAULT_GATEWAY
!*************************** OWNER ***************************
owner HLRLDAP

    add service KPG-HV30-6

So, I should have change my config like this:

    ip virtual-router 1 priority 101

    ip redundant-interface 1 172.19.145.181
    ip critical-service 1 PING_DEFAULT_GATEWAY
circuit VLAN550
ip address 192.168.50.18 255.255.255.0
    ip virtual-router 2 priority 101
    ip redundant-interface 2 192.168.50.20
    ip critical-service 2 PING_DEFAULT_GATEWAY

Unable to add/remove users in Mountain Lion Server (Options are greyed out)

For some reason, im unable to add/remove users in Mountain Lion server. The + and - are greyed out. It seems like something is wrong with the permissons because it looks like it cant write the the Ldav3 file (although that may be speculation). Does anyone have any advice for me? I URGENTLY need to add users.
Maybe theres a way to restore default permssions for the boot drive (if that in fact is the issue). Hopefully there is a way that I can fix this while leaving all users, groups, their permissions and shares intact.

Anything interesting and relevent in the server logs?
Anything interesting in the server alerts?
Since it's far and away the most common cause of problems with OS X Server and with distributed authentication (Open Directory is entirely based on network encryption and digital certificates and on responses from your local DNS server(s)), verify your local DNS configuration is working and requires no changes with the following Terminal.app (Applications > Utilities) harmless, diagnostic command:
sudo changeip -checkhostname
sudo requires an administrative password. You might get a one-time warning about the sudo, and that can safely be ignored. The command will display some details, and indicate whether the local configuration appears valid and no changes are required, or further diagnostics for (most) common errors that can arise.

Unable to load the user interface-please reinstall the application-Audigy 2 zs Platinum

unable to load the user interface-please reinstall the application---this is the message I get when my pc starts------Someone messing around with my computer tried to delete creative media source player 3 when they saw I had both 3 and 5 in folder and i get this error message every time I start my pc. In addition to this I have lost my EAX and THX consoles and my speaker settings are gone so I cannot adjust my 5. system at all. After I delete that error message when I click on the creative icon is sys tray instead of opening up the creative media player I get the error message--unable to load needed componants. Please reinstall the application. this is media player 3[version 3.32.]. I dont know why during the auto?updates through the last couple of years I have media player 3 in sys tray and if I need version 5 it is in file with 3--start-all programs-creative--any way my pc is a Cyberpower AMD FX-53 using win xp pro-32 bit-- and of course its a OEM product so they tell me the only way to get it to work is use the restoration cd they gave me when I bought the pc and it will revert back to its original state as when purchased. I would lose all my games, music, pictures?ect and would have to start from scratch.[ OR of course back everything up on a portable hard dri've]?It seems like there should be an easier way --hell I might as well buy a new soundcard and it would make it easier. If anyone?has an answer for someone who is not a tech head so I can understand please help !!--thank you in advance for any assistance as it is greatly appreciated. Sorry this message is so long winded, just irritating to have spen so much for a pc and not have the original installation disc.-tried moving to another slot and the fixes I saw posted here with no luck---thank you folks again--Tom

All the issues you guys are talking about have been reported in beta stage of these new drivers. I would say none of them has been fixed yet. The only solution for now is to use previous drivers which work fine or use some modified drivers which fixes some issues, but not all. Your choice.

ORA-01654: unable to extend index user.index_x by 16 in tablespace tablespa

Hi all,
I get the error message : ORA-01654: unable to extend index user.index_x by 16 in tablespace tablespace_t after an insert into table table_x(having the index index_x ).
Could you please help me ? Should I add new datafile? Is there any other solution
I have get this message before, I have added new datafile to this tablespace,
ALTER TABLESPACE tablespace_t ADD DATAFILE 'C:\APP\...\ORADATA\MABASE\S_TAB_user02.DBF' SIZE 500M
AUTOEXTEND ON NEXT 100M MAX SIZE 1000M;
TABLESPACE_NAME ALLOUE OCCUPE LIBRE
1 tablespace_t 5720 5421 297

i think that would work.. And also if the error still persists then you have to tune the queries which are cost effective..For that you have to wait until you get the same error after addition of the datafile..Cheers!

Hi,
Thanks for your post.
Have you configured the client to only use user authentication for 802.1X? If so, I would like to inform you that this is expected when you configure the 802.1X to user only authentication.
Here is the process that is followed.
1. As soon as client is connected to the network the Authenticator (switch) periodically sends EAP request packet/frame to the client/supplicant.
2. The client has to respond back with an identify and if its configured only for User authentication then it will send blank identity.
3. The Authenticator cannot validate and the authentication would fail.
4. Windows client is configured for a block time of 20 min. So, once the authentication fails the NIC card will go in block time for 20 min until there is a change in credentials. So, even if the authenticatior(swithch) is periodically sending EAP request
it will just ignore them
5. You will see event 15506 after the event 15514.
Here’s the technet that you we can refer for the reason code : Reason: 0x50001 that we see in the event 15514
http://technet.microsoft.com/en-us/library/cc727747(WS.10).aspx
0x50001 = Dec 327681
Reason code: 327681   Event log message: The 802.1X module was unable to identify a set of credentials to be used. [An example is when the authentication mode is set to “User” but no user is logged on.]   # def name:

Hello Thomas,
It looks like a Solaris issue. Check if the home directory
/home is reserved in the Solaris configuration.
Check if this fix the problem please perform the following steps:
1. modify /etc/auto_master file to change the entry for '/home' to say
'/autohome' instead
2. reboot
3. rmdir /home
4. ln -s /export/home /home (make sure /export/home exists)
Also you could create soladm manually in advance.
Hope this helps,
Dolores

Unable to Telnet...............

Hi,
I have two IP's Configured on my Cisco 2800. 1.1.1.1 - Loopback and 2.2.2.2 on Fast Ethernet. Both IP's are pingable across the WAN. And telnet to loopback IP is working fine. However I am unable to telnet to Fast Ethernet IP. The error message while trying to telnet to Fast Ethernet IP is: "Could not open connection to the host, on port 23: Connect failed". I tried to debug telnet on the router. The Debug output for unsuccessful telnet is as follows:
Telnet194: recv SB NAWS 139 24
However for a successful telnet session, the output is:
