Strange x25 problem -fixed but I dont know why.

[Paula J Frazer-Campbell]

Hi to all

As part of my x25 configuration I use the x29hosts file to push my x25 users through a login file.

X29hosts example:-

# for x29server
pad_spt {
remote_x121 *
local_x121 00001166110000
application /avro/DATA/x25login_0
size_parity 7_even
logging 1
x3 hp_padsrvr1
reverse_charge disable
}

# for x29server
pad_spt {
remote_x121 *
local_x121 00001166110001
application /avro/DATA/x25login_2
size_parity 7_even
logging 0
x3 hp_padsrvr1
reverse_charge disable
}
This above an extract from my current working file.

Mid afternoon Friday I lost all x25 users - investigation showed x29server sessions (users connecting) but users not going through the login script.

I copied all x3, x25 and x29 files in /etc/x25 aside and replaced them with files from a backup - problem solved.

My x29hosts file had changed and the:-
reverse_charge disable

Had changed to :-
reverse_charge DISABLE (upper case)

The only additional item to normal that I was running was make_tape_recovery, which I have run in the past on a live server without problems.

When I lost my x25 users the make_tape_recovery session hung (related?)

Sorry its so long a question, but had to give y'all the info -
So what went wrong?

Any pointers wost welcome.

hi, paula
can u check the tape which u was using during recovery tape, may be the /etc/x25 user file may not be in the recovery tape, that might caused the problem.

Hi Ravi

Good idea but I was creating a tape at the time and yes there may be no x25/x29/x3 files on the tape as the server had not yet written them.

Hi paula,
do have seperate back up of the root file system(which will be having all the users account) if anything case like this we can recover from the root backup

Hi Ravi

My system is up and running as I fixed the problem by replacing the x3/x29/and x25 files from a backup on the day it happened (Friday).

I am now trying to find out why it happened.
