from home Pinger showing everything ok, however email or putty unable to connect.
isup.me showing email.nmlindia.org as ok. Found redirection/reverse proxies working. But putty through BSNL ip not working. email.nml.in is working without any problem.
Looks BSNL has some problem.
After login to ldap1 with nkn ip did the following:
checked local accessibility to port 80

ITS DEFINITEY A BSNL BOADBAND ISSUE I HAVE NO IDEA WHO in BSNL WILL UNDERSTAND AND RESOLVE. somewhere they are blocking traffic from BB to our IP

Many people (like Rakesh) still reporting problem in NMLN connectivity. Check radius radius2 APs found no problem. Many users are connected and working without problem.
Later found Disk space problem in logserver (it was full). Since it has a 6 GB hda need to upgrade to higher. for the time being deleted the /tmp contents, freed 1GB then rebooted.
NMLN issue unable to connect
Checked syncdhcp script found no issues. But non of the system is connecting to NMLN auth not reaching radius. At last found DWL-3200 has an issue which resolved after reboot. Conclusion:
- WPA auth needs radius server which should be reachable and working before a client(AP) tried to access it.
- Power shutdown on sunday switched off everything. After the power resumed all APs gone up but the server UPS was down (as result all servers were down). The Radius was unavailable and APs continue rejecting any WPA request without rechecking availability of radius again. On rebooting now it (APs) was able to get radius and started working.
- For any future problem the sequence of “Radius UP before Clients” need to be ensured.
Designing form for TR@NML and problem wifi/acsir
From morning engaged for troubleshooting acsir/NMLN/wifi wireless access problem. Three systems gone down due to power failure and may be surge on sunday. Endian is down tried changing the SMPS from one of the system waiting for writeoff. But unable to understand the problem. Endian hangs in few minutes and not accessible through network. though the card is ok. local console also not working.
clustpc3 is also hanging in few minutes. dlserver going down in 5 to 10 minutes. In DLSERVER found rsyslogd hogging the CPU 100%. killed it and then run dlserver, now looks ok.
unable to do anything to clustpc3 then configured clustpc6 with zeroshell and conncted to NKN with NAT. redirected zeroshell of VM to it for wifi to work. tested and its working ok.
clustpc5 (acsir) was not working due to failure of endian. created a VLAN connection to BSNL and directed to via this. tested and acsir now working ok.
NMLN rejecting my mobile (also Rachit Ghosh’s laptop), checked my MAC is listed in banned list of ldap1 iptables. May be some problem in syncdhcp script need to debug. taken print for homework.
Identifid variables and type for the TR@NML form did not get much time. Need to do tomorrow.
Upgrading HDD and RAM of nmlsitea(oleinfo,MatDB,safewater etc.)
reduced size of host lv
created another lv of 18.7 gb
added lv to guest as another hdd
gone init 1 then with dd copied source to destination hdd inside nmlsitea
with fdisk checked last cyl of the new hdd and changed endcyl of part 2(create new, check last cyl, del new, del part2, create new with part2 begcyl and above found end cyl)
extended phy vol of new hdd with pvextend
shutdown nmlsitea . removed the hdds, added new hdd again as hda and ide interface.
found free PE by using lvdisplay(it is 303)
used
lvextend -l +303 /dev/VolGroup00/LogVol00
to extend the LV
resize2fs /dev/VolGroup00/LogVol00
Process is complete. Here is some outputs.

Retured from Cuttack after spending 30th Dec 2013 to 3rd Jan 2014 (Also Puri on 2nd Jan).
Tested all server RAM, two are bad and retured to party for replacement. Received SmartCards and printed the first lot on last Friday (10/01/2014). Also received the BioTA reader X-990 model instead of U-990. Tested logging and smart card . Our Cards will not be compatible to the new reader.
Railtel did not provide connectivity of 4Mbps to MNP asked to provide reason and date for completion of the order.
