Remove need for /usr/local/bin
The half hourly job to ping all the active PingER hosts is at ~cottrell/bin/pinger_startup.pl. It in turn calls pinger2.pl to make the measurements.
In CentOS there is no /usr/local/bin so we need to make the following change in pinger_startup, and after testing restore
#my $PERL_PATH="/usr/local/bin/perl";
my $PERL_PATH="/usr/bin/perl";
Failure to restore $PERL_PATH results in email with:
| Can't locate XML/Simple.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at /afs/slac/package/pinger/pinger2/share/pinger/pinger2.pl line 450.

Access to /nfs
INC0346900:
I am unable to access the following /nfs file on pinger-test.pl from either the pinger or cottrell accounts, but am able to access it from the cottrell@pinger.slac.stanford.edu or pinger@pinger.slac.stanford.edu accounts:
[pinger@pinger-test ~]$ ls -l /nfs/slac/g/net/pinger/pinger2/data//ping-2022-01.txt
ls: cannot access /nfs/slac/g/net/pinger/pinger2/data/ping-2022-01.txt: No such file or directory
[cottrell@pinger-test ~]$ ls -l /nfs/slac/g/net/pinger/pinger2/data//ping-2022-01.txt
ls: cannot access /nfs/slac/g/net/pinger/pinger2/data/ping-2022-01.txt: No such file or directory
However I can access it from cottrell@pinger
[cottrell@pinger ~]$ ls -l /nfs/slac/g/net/pinger/pinger2/data/ping-2022-01.txt
-rw-r--r-- 1 pinger sf 66517964 Jan 6 16:37 /nfs/slac/g/net/pinger/pinger2/data//ping-2022-01.txt
or pinger@pinger
[pinger@pinger ~]$ ls -l /nfs/slac/g/net/pinger/pinger2/data/ping-2022-01.txt
-rw-r--r-- 1 pinger sf 66709377 Jan 6 16:47 /nfs/slac/g/net/pinger/pinger2/data/ping-2022-01.txtPinger-test has not been given access to NFS. (This managed by host, not user.)
Looking in more detail /nfs/slac is not accessible from cottrell@pinger-test
[cottrell@pinger-test ~]$ ls -l /nfs/slac
ls: cannot access /nfs/slac: No such file or directory
Pinger-test has not been given access to NFS. (This managed by host, not user.)
trscrontab -e
escrow edit -c netdev cottrell
I note that escrow does not seem to work on pinger-test or cent7a
[cottrell@pinger-test ~]$ escrow edit -c netdev cottrell
escrow: Command not found.
Put the following in ~cottrell/.cshrc
alias escrow "perl /afs/slac.stanford.edu/package/scsutils/scripts/escrow"
alias trscrontab /afs/slac.stanford.edu/package/scsutils/src/trs/cron/trscrontab
For pinger, put the following in ~pinger/.bash_profile
alias escrow="perl /afs/slac.stanford.edu/package/scsutils/scripts/escrow"
alias trscrontab=/afs/slac.stanford.edu/package/scsutils/src/trs/cron/trscrontab
I now get:
[cottrell@pinger-test ~]$ escrow edit -c netdev cottrell
/afs/slac.stanford.edu/package/console/@sys/slacmsg: error while loading shared libraries: libgssapi_krb5.so.2: cannot open shared object file: No such file or directory

I think you can ignore the error from slacmsg. It is just a logging issue.
Since slacmsg is 32bit and depends on a lots of 32bit libraries, I am not sure I should install all of them, especially those 32bit PAM related libraries.
