Don't forget to use the chkconfig capability to really see what processes are running at each specific runlevel.
Paul >>> [EMAIL PROTECTED] 06/27/03 11:25AM >>> I will state up front that I am not that familiar with the organization used for Linux run levels. Having said that: in my experience run levels 2 and 3 are both fully functional, and not used for backups as you are suggesting. In some systems I have used run level 2 had everything enabled, and run level 3 was everything except networking (no rsh, rcp, rlogin, telnet, ftp, etc.). You may want to look at what some of the other run levels do. You may find that run level 4, or 5 are not used, and you could implement what you want as one of these. As for telnet: it starts from inetd, which probably starts from the S05network script. It should be configured in /etc/inetd.conf. -----Original Message----- From: James Melin [mailto:[EMAIL PROTECTED] Sent: Friday, June 27, 2003 8:08 AM To: [EMAIL PROTECTED] Subject: Changing runlevels etc I have been reviewing the start/stop functions within the various rcx.d entries and I think I have a handle on this....but I want to run this past the reflecting pool of wisdom known as the Linux-390 list. What I believe I need to do in order to get my boulder sized backups without taking the linux LPAR all the way down/up is this: Change to runlevel 2, and let the system handle getting various things down through normal channels. Runlevel 2 is going to start the following, by default (not sorted by number - sorry) S02dhclient S10at S05network S10mysql S07route S10quota S08proftpd S10raw S08snmpd S11lpd S01SuSEfirewall_init S08syslog S11smbfs S01dummy S10acct S11xntpd S01random S10argus S12cron My question is this: Where does telnet get started, will it stay active through a runlevel 3-2 shift and if not how does one start it. Secondly, since I don't use the SuSE Firewall, is there a point to me having this in rc2.d? I also wont need the SMBFS or mysql started. I'm just loathe to remove things from rc2.d since they are 'stock' and would be replaced in an OS upgrade Why runlevel 2? I want everything to halt so I can run a script that will take the file systems one by one and mount them read only and initiate a dd disk copy to a matching set of spare volumes. I'm not sure that I want the system in single user mode, since our operators really don't have anythign to do with this, and I want to be able to telnet into the box if I have to dial into work to fix things. Once the dasd has been mirrored, I want to take it offline to linux, send the system back to runlevel 3 and continue on. The one problem I'm having is with a component of DB2 connect coming up. I have had to manually issue db2start from the db2inst1 ID after the system is up, so I also need to know if it's possible for a script to do an su to the db2inst1 ID and still issue a command when it's time to bring the system back to runlevel 3 any examples of unix shell scripts that do things like this I could see would be most helpful. All this for lack of a backup client that doesn't suck, since I cant play in the 3494 because nobody here trusts linux/amanda to handle it properly
