[Serusers] Re: Ser fails to start if Mysql.so is loaded.
by Younger Wang 13 Jun '03

13 Jun '03

Both Andrei and Daniel are right. By default, mysql.so is not compiled and installed. If mysql.so is configured to loaded and mysql.so is not found in the library, a " bad config file" error will appear when ser is started. I did not see this error because I installed ser0.8.10 before and the obsolete mysql.so existed in the library.

[Serusers] Compilation error
by mjkane＠cape.com 12 Jun '03

12 Jun '03

Hello, I'm tring to compile ser-0.8.11pre29 using make all. I am running Redhat 8.0. The ser-0.8.11pre29.rpm install with no problem, but I noticed a posting that the generic install doesn't support mysql modules. So in a nutshell it make sense to compile from scratch making it easier to add patches in as the are built(ie...pre31). Below is the error message I'm gettin. Extra objs: gcc -Wl,-O2 -Wl,-E action.o crc.o data_lump.o data_lump_rpl.o dprint.o dset.o error.o fifo_server.o flags .o forward.o hash_func.o ip_addr.o main.o md5.o md5utils.o modparam.o msg_translator.o pass_fd.o proxy.o rec eive.o resolve.o route.o route_struct.o script_cb.o sr_module.o stats.o tcp_main.o tcp_read.o timer.o udp_se rver.o mem/f_malloc.o mem/mem.o mem/memtest.o mem/q_malloc.o mem/shm_mem.o mem/vq_malloc.o parser/hf.o parse r/msg_parser.o parser/parse_content.o parser/parse_cseq.o parser/parse_event.o parser/parse_expires.o parser /parse_fline.o parser/parse_from.o parser/parse_hname2.o parser/parse_hostport.o parser/parse_nameaddr.o par ser/parse_param.o parser/parser_f.o parser/parse_rr.o parser/parse_to.o parser/parse_uri.o parser/parse_via. o parser/digest/digest.o parser/digest/digest_parser.o parser/digest/param_parser.o parser/contact/contact.o parser/contact/parse_contact.o db/db.o lex.yy.o cfg.tab.o -lfl -ldl -lresolv -o ser /usr/bin/ld: cannot find -lfl collect2: ld returned 1 exit status make: *** [ser] Error 1 Thanks Mike

Sorry, here is what I wanted to express in last letter. Ser starts normally with the default ser.cfg. When I uncommented the line load module "/usr/local/lib/ser/modules/mysql.so" to load mysql.so, everything seems normally. But actually, ser stops abnormally. Thanks! Younger Wang

[Serusers] defunct process
by Wong Tsang Han 11 Jun '03

11 Jun '03

Hello All, I have installed ser-0.8.11pre29-1 on RedHat 9.0. When I start ser by script /etc/init.d/ser or directly using /usr/sbin/ser, the process SOMETIMES hangs at the Aliases line show below. When I list the process table, I observed there was a defunct process. Now, this does not happen ALL the time when I starts ser. Sometime, /use/sbin/ser or init script will start fine without a hiccup. I also notice that the defunct process is ALWAYS the second lowest process id among all ser processes. Can this be a case of race condition for the parent process to exit without waiting for the child? I did not encounter this using ser-0.8.10 on RedHat 7.3. However, I do remember encountering this behavior once when running ser-0.8.10 on RedHat 9.0, I have removed 0.8.10 and installed 0.8.11 since then for testing 0.8.11. Could this be a problem of RedHat 9.0? Is anyone experience this or am I the only one?

[Serusers] Proxy just stops processing INVITE messages
by Jamin W. Collins 07 Jun '03

07 Jun '03

Got another oddity at the same site as before. This morning, th proxy server appears to have simply stopped processing INVITE requests. It continued to process and log REGISTER requests. The ngrep process I have running to log traffic shows the inbound INVITE request, but nothing after it, no response, no additional INVITE, nothing. Again, I have ngrep traffic logs for the period if they would help. Although I have not yet increased the debug level on the process. Was hoping something would come of the information I forwarded to serhelp first. However, I'll be increasing the logging level tonight. Other ideas? -- Jamin W.

[Serusers] Re: First tests with nathelper
by Maxim Sobolev 07 Jun '03

07 Jun '03

I've just committed into the cvs the autopinging feature useful to keep NAT bindings alive. If possible, please test and let me know then. Basically, everything you need to do is to recompile/reinstall ser and all modules and add the following into your config: modparam("nathelper", "natping_interval", N) Where N is some non-zero interval in seconds (usually 15-30 should be OK). Thanks! -Maxim On Tue, Apr 29, 2003 at 09:38:44PM +0100, jaime(a)umtstrial.co.uk wrote: > Hello Maxim, > > I have been trying your module on one server with a customised > configuration, very similar to the default one in nathelper.cfg.
