Hi List,
We are running into a problem with large groups on ubuntu 16.04. Hesinfo returns the correct record but getent does not.
rf@odinseye:~$ hesinfo workshop group
workshop:x:2029:fugon,dshill,rpnagarajan,tkremin,dalhindi,cprator,niyer,lixinzhe,rbellone,abzzram,paulae,sefeeney,yyaqiaoo,oanh,yiklim,joshi,skinnerjs,mclewis,jltanaka,dlebron,malbrown,xycheng,jli,shiqizh,kroy,bpdurbin,emilyk,csbenton,sharifdvm,bridget,nikj,mltu,kjennings,alaahmed,rkallen,lifswaro,datawrangler,jennifermoussa,ruta,jaime,markjs,zephyryi,ghanna,jbmiesfeld,shayne,cjjacob,mquesta,limchen,ajmichael,sfyanw,carfranc,agingrich,kluepdan,minyuan,arios,yangx,msettles,adwright,pmhenry,acartwright,kmlewald,devanmurphy,loxiles,yuabai,hforbes,onoses,eokello,ghwada,jfass,jabaily,cincinhuang,yaoluo,stafford,sleepery,ragrahn,karin,rf,mbritton,hergarden,cpinzari,ebattivelli,vwang
rf@odinseye:~$ getent group workshop
rf@odinseye:~$ echo $?

The workshop.group.ns record is in in a single TXT record in DNS like this:
"workshop:x:2029:fugon,dshill,rpnagarajan,tkremin,dalhindi,cprator,niyer,lixinzhe,rbellone,abzzram,paulae,sefeeney,yyaqiaoo,oanh,yiklim,joshi,skinnerjs,mclewis,jltanaka,dlebron,malbrown,xycheng,jli,shiqizh,kroy,bpdurbin,emilyk,csbenton,sharifdvm,bridg" "et,nikj,mltu,kjennings,alaahmed,rkallen,lifswaro,datawrangler,jennifermoussa,ruta,jaime,markjs,zephyryi,ghanna,jbmiesfeld,shayne,cjjacob,mquesta,limchen,ajmichael,sfyanw,carfranc,agingrich,kluepdan,minyuan,arios,yangx,msettles,adwright,pmhenry,acartw" "right,kmlewald,devanmurphy,loxiles,yuabai,hforbes,onoses,eokello,ghwada,jfass,jabaily,cincinhuang,yaoluo,stafford,sleepery,ragrahn,karin,rf,mbritton,hergarden,cpinzari,ebattivelli,vwang"
I was perusing the nss_hesiod directory in the glibc (2.23) source package for ubuntu 16.04 and also the source for the utility hesinfo and it looks like the version in glibc may not be new enough to support responses larger than 1024 bytes. Does that sound accurate?
In hesiod.c for the hesinfo program I see:
/* Construct the query. */
n = res_mkquery(QUERY, name, C_IN, T_TXT, NULL, 0, NULL, qbuf, PACKETSZ);
Whereas in nss_hesiod I see:
/*
* Construct the query and send it.
*/
n = res_mkquery(QUERY, name, class, T_TXT, NULL, 0, NULL, qbuf, MAX_HESRESP);
Am I on the right track here?
Thanks!
Richard
